    Resumen IntroducciÓn: El papiloma invertido es una neoplasia benigna de los senos paranasales localmente agresiva con alto potencial de recurrencia y de malignización. La extensión intracraneal es infrecuente y más aún, la penetración dural, asociándose a menudo a la recurrencia de la enfermedad o a su degeneración en carcinoma de células escamosas. Caso clínico: Presentamos el caso de una paciente de 32 años que consultó por lesión exofítica en fosa nasal derecha y exoftalmos, asociada a cefalea, anosmia y disgeusia. Se estudió con TC cerebro, macizo facial y RM de encéfalo que evidencian lesión en fosa nasal derecha con ocupación de senos aéreos, osteólisis de pared medial orbitaria y base de cráneo anterior e invasión intracraneal frontal derecha, con efecto de masa y compresión del parénquima encefálico adyacente. Intervención: Se realizó una nasofibroscopía en primer tiempo con diagnóstico anatomopatológico de papiloma invertido y posteriormente resección de la lesión mediante doble abordaje más reconstrucción de la fosa craneal anterior. Se obtuvo diagnóstico definitivo de papiloma invertido de tipo Schneideriano con áreas de transformación atípica in situ. La paciente evolucionó de forma favorable y sin complicaciones, con permeabilidad de vía aérea superior, sin signos de recidiva lesional luego de 4 años de seguimiento. Conclusión: La invasión intracraneal de esta patología es sumamente infrecuente. Cuando existe, es indicador de agresividad y potencial recidiva, por lo que la exéresis completa de la misma define el pronóstico de la enfermedad. PMID:29430328

    Subacute subdural hematomas are a poorly individualized nosological entity, often equated clinically to chronic subdural hematomas. Yet, their neurological deterioration which is usually rapid seems to distinguish them from chronic subdural hematomas. We wanted to show this dangerousness by establishing the clinically evolving profile of the three types of subdural hematomas. This was a prospective and retrospective study of 63 subdural hematoma (18 acute, 13 subacute, and 32 chronic) patients admitted between 2012 and 2014 in the neurosurgery unit of Lomé University Hospital. Hematomas were classified according to the elapsed time after head injury and blood density on CT. The main parameter studied was the evolution of the Glasgow Coma Score (GCS) in the 3 months following the trauma, enabling to establish an evolving profile of each type of hematoma. The average age of patients was 58.1 years for chronic subdural hematomas and 47.6 years for subacute subdural hematomas. Disease duration before admission was 13.1 days for chronic against 36.6 h for subacute hematoma. The clinical profile shows acute worsening within hours during the second week for patients with subacute hematoma, while it is progressive for patients with chronic hematoma. We noted two deaths, all victims of a subacute hematoma (one operated, one patient waiting for surgery). Iso-density hematoma on CT, especially in a young person, must be considered as a predictive factor of rapid neurological aggravation suggesting an urgent care or increased monitoring by paramedics.

    Patient: Male, 41 Final Diagnosis: Healty Symptoms: Headache Medication: — Clinical Procedure: Chronic subdural hematoma Specialty: Neurosurgery Objective: Diagnostic/therapeutic accidents Background: Chronic subdural hematoma generally occurs in the elderly. After chronic subdural hematoma evacuation surgery, the development of epidural hematoma is a very rare entity. Case Report: We report the case of a 41-year-old man with an epidural hematoma complication after chronic subdural hematoma evacuation. Under general anesthesia, the patient underwent a large craniotomy with closed system drainage performed to treat the chronic subdural hematoma. After chronic subdural hematoma evacuation, there was epidural leakage on the following day. Conclusions: Although trauma is the most common risk factor in young CSDH patients, some other predisposing factors may exist. Intracranial hypotension can cause EDH. Craniotomy and drainage surgery can usually resolve the problem. Because of rapid dynamic intracranial changes, epidural leakages can occur. A large craniotomy flap and silicone drainage in the operation area are key safety points for neurosurgeons and hydration is essential. PMID:26147957

    Purpose To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS) score, and intracerebral hematoma (ICH) score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality. Materials and Methods This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA) and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC) were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant. Results The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018), 0.715 (P = 0.0008) (by ABC/2) to 0.738 (P = 0.0002) (by CAVA), 0.877 (P<0.0001) (by ABC/2) to 0.882 (P<0.0001) (by CAVA), and 0.912 (P<0.0001), respectively. Conclusion Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score. PMID:25029592

  11. Management of Recurrent Subdural Hematomas.

    Desai, Virendra R; Scranton, Robert A; Britz, Gavin W

    2017-04-01

    Subdural hematomas commonly recur after surgical evacuation, at a rate of 2% to 37%. Risk factors for recurrence can be patient related, radiologic, or surgical. Patient-related risk factors include alcoholism, seizure disorders, coagulopathy, and history of ventriculoperitoneal shunt. Radiologic factors include poor brain reexpansion postoperatively, significant subdural air, greater midline shift, heterogeneous hematomas (layered or multi-loculated), and higher-density hematomas. Surgical factors include lack of or poor postoperative drainage. Most recurrent hematomas are managed successfully with burr hole craniostomies with postoperative closed-system drainage. Refractory hematomas may be managed with a variety of techniques, including craniotomy or subdural-peritoneal shunt placement. Copyright © 2016 Elsevier Inc. All rights reserved.

    Chronic subdural hematoma (CSDH), a common condition in elderly patients, presents a therapeutic challenge with recurrence rates of 33%. We aimed to identify specific prognostic factors for recurrence using quantitative analysis of hematoma volume and density. We retrospectively reviewed radiographic and clinical data of 227 CSDHs in 195 consecutive patients who underwent evacuation of the hematoma through a single burr hole, 2 burr holes, or a mini-craniotomy. To examine the relationship between hematoma recurrence and various clinical, radiologic, and surgical factors, we used quantitative image-based analysis to measure the hematoma and trapped air volumes and the hematoma densities. Recurrence of CSDH occurred in 35 patients (17.9%). Multivariate logistic regression analysis revealed that the percentage of hematoma drained and postoperative CSDH density were independent risk factors for recurrence. All 3 evacuation methods were equally effective in draining the hematoma (71.7% vs. 73.7% vs. 71.9%) without observable differences in postoperative air volume captured in the subdural space. Quantitative image analysis provided evidence that percentage of hematoma drained and postoperative CSDH density are independent prognostic factors for subdural hematoma recurrence.

    The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. Copyright © 2014 Elsevier Inc. All rights reserved.

    Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas. Ultrasound can be an effective modality to diagnose subdural hematoma when no epidural blood is visualized. We have reviewed the literature and present a full literature review and a case presentation of an 82-year-old male who developed a thoracolumbar spinal subdural hematoma after spinal epidural anesthesia. Anticoagulant therapy is an important predisposing risk factor for spinal epidural hematomas and likely also predispose to spinal subdural hematomas. It is important to consider spinal subdural hematomas in addition to spinal epidural hematomas in patients who develop weakness after spinal epidural anesthesia, especially in patients who have received anticoagulation.

    Coexistence of cranial and spinal subdural hematomas is rare and only a few cases have been reported in the literature. Herein, we report a case of cranial and spinal subdural hematomas after previous head trauma. As the pathogenesis of simultaneous intracranial and spinal subdural hematoma yet remains unclear, we developed an alternative theory to those proposed in the literature for their coexistence, the migration of blood through the subdural space.

  17. Hematoma Expansion Following Acute Intracerebral Hemorrhage

    2013-01-01

    Intracerebral hemorrhage, the most devastating form of stroke, has no specific therapy proven to improve outcome by randomized controlled trial. Location and baseline hematoma volume are strong predictors of mortality, but are non-modifiable by the time of diagnosis. Expansion of the initial hematoma is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for hematoma expansion have been identified, including baseline ICH volume, early presentation after symptom onset, anticoagulation, and the CT angiography spot sign. Although the biological mechanisms of hematoma expansion remain unclear, accumulating evidence supports a model of ongoing secondary bleeding from ruptured adjacent vessels surrounding the initial bleeding site. Several large clinical trials testing therapies aimed at preventing hematoma expansion are in progress, including aggressive blood pressure reduction, treatment with recombinant factor VIIa guided by CT angiography findings, and surgical intervention for superficial hematomas without intraventricular extension. Hematoma expansion is so far the only marker of outcome that is amenable to treatment and thus a potentially important therapeutic target. PMID:23466430

    Interdural hematomas are primarily observed in infants, and adult interdural hematomas are rare. We describe a 54-year-old woman with a round, well-defined mass. The mass was an interdural hematoma that was misdiagnosed as an epidural hematoma. Unlike an epidural hematoma, interdural hematomas are located between the two layers of the dura mater, and the dural tail sign can be observed. PMID:28664008

  20. Catheter placement for lysis of spontaneous intracerebral hematomas: does a catheter position in the core of the hematoma allow more effective and faster hematoma lysis?

    For the fibrinolytic therapy of intracerebral hematomas (ICH) using recombinant tissue plasminogen activator (rtPA), a catheter position in the core of the hematoma along the largest clot diameter was assumed to be optimal for an effective clot lysis. However, it never had been proven that core position indeed enhances clot lysis if compared with less optimal catheter positions. In this study, the impact of the catheter position on the effectiveness and on the time course of clot lysis was evaluated. We analyzed the catheter position using a relative error calculating the distance perpendicular to the catheter's center in relation to hematoma's diameter and evaluated the relative hematoma volume reduction (RVR). The correlation of the RVR with the catheter position was evaluated. Additionally, we tried to identify patterns of clot lysis with different catheter positions. The patient's outcome at discharge was evaluated using the Glasgow outcome score. A total of 105 patients were included in the study. The mean hematoma volume was 56 ml. The overall RVR was 62.7 %. In 69 patients, a catheter position in the core of the clot was achieved. We found no significant correlation between catheter position and hematoma RVR (linear regression, p = 0.14). Core catheter position leads to more symmetrical hematoma RVR. Faster clot lysis happens in the vicinity of the catheter openings. We found no significant difference in the patient's outcome dependent on the catheter position (linear regression, p = 0.90). The catheter position in the core of the hematoma along its largest diameter does not significantly influence the effectiveness of clot lysis after rtPA application.

    Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. To investigate whether splitting the inner hematoma membrane influences the recurrence rate in patients undergoing burr-hole craniotomy for CSDH. Fifty-two awake patients undergoing surgery for 57 CSDHs were prospectively randomized to either partial opening of the inner hematoma membrane (group A) or not (group B) after enlarged burr-hole craniotomy and hematoma evacuation. Drainage was left in situ for several days postoperatively. Groups were comparable with regard to demographic, clinical, and imaging variables. Outcome was assessed after 3-6 weeks for the combined outcome variable of reoperation or residual hematoma of one third or more of the original hematoma thickness. Fourteen patients underwent reoperation for clinical deterioration or residual hematoma during follow-up (n = 6 in group A, 21%; n = 8 in group B, 28 %) (P = 0.537). Residual hematoma of ≥ one third not requiring surgery was present in 7 patients in group A (25%) and 10 patients in group B (36%) (P = 0.383). The overall cumulative failure rate (reoperation or hematoma thickness ≥ one third) was 13/28 (46%) in group A and 18/28 in group B (P = 0.178; relative risk, 0.722 [95% confidence interval, 0.445-1.172]; absolute risk reduction -16% [95% confidence interval, -38% to 8%]). Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

    We report a case of an infected subdural hematoma that occurred 1 year after burr-hole irrigation for chronic subdural hematoma. A 78-year-old woman who had developed left hemiparesis was admitted to our hospital. A computed tomography(CT)scan revealed the presence of a chronic subdural hematoma in the right hemisphere. Her clinical symptoms improved immediately after emergency burr-hole irrigation, which allowed her discharge from the hospital. One year after the initial surgery, she developed an infection of the urinary tract infection, which led to severe pyelonephritis and septic shock. Treatment of the urological symptoms eliminated the systemic inflammation. One month after the urinary infection, the patient was readmitted to the hospital in a comatose state. A CT scan showed regrowth of a residual subdural hematoma surrounded by a thick capsule, causing a midline shift in the brain. An emergency operation for removal of the subdural hematoma by burr-hole irrigation was performed, and pus was drained from the subdural mass. Microbiological cultures of the abscess revealed the presence of Proteus mirabilis. After surgery, the patient was administered an antibiotic treatment for three weeks and she was discharged with no neurological deficits. Cultures of blood from the septic shock as well as from the abscess both revealed the presence of Proteus mirabilis. Therefore, a diagnosis of infected subdural hematoma, which was caused by hematogenous infection, was made. We conclude that attention should be paid to the risk of infection of the hematoma capsule in subdural hematomas.

    A multicentered retrospective case series. To determine the incidence and circumstances surrounding the development of a symptomatic postoperative epidural hematoma in the cervical spine. Patients who underwent cervical spine surgery between January 1, 2005, and December 31, 2011, at 23 institutions were reviewed, and all patients who developed an epidural hematoma were identified. A total of 16 582 cervical spine surgeries were identified, and 15 patients developed a postoperative epidural hematoma, for a total incidence of 0.090%. Substantial variation between institutions was noted, with 11 sites reporting no epidural hematomas, and 1 site reporting an incidence of 0.76%. All patients initially presented with a neurologic deficit. Nine patients had complete resolution of the neurologic deficit after hematoma evacuation; however 2 of the 3 patients (66%) who had a delay in the diagnosis of the epidural hematoma had residual neurologic deficits compared to only 4 of the 12 patients (33%) who had no delay in the diagnosis or treatment ( P = .53). Additionally, the patients who experienced a postoperative epidural hematoma did not experience any significant improvement in health-related quality-of-life metrics as a result of the index procedure at final follow-up evaluation. This is the largest series to date to analyze the incidence of an epidural hematoma following cervical spine surgery, and this study suggest that an epidural hematoma occurs in approximately 1 out of 1000 cervical spine surgeries. Prompt diagnosis and treatment may improve the chance of making a complete neurologic recovery, but patients who develop this complication do not show improvements in the health-related quality-of-life measurements.

    An 88-year-old woman presented with acute subdural hematoma (ASDH) which showed rapid resolution on computed tomography (CT) and magnetic resonance (MR) imaging. She was transferred to our hospital after falling out of bed. On admission, she was comatose with Japan Coma Scale score of 200 and Glasgow Coma Scale score of E1V1M2. Brain CT showed a thick left frontotemporal ASDH. Conservative treatment consisted of 200 ml of glycerol administered intravenously twice a day, and maintenance in the approximately 20 degree head-up position to reduce intracranial pressure. Three days later, her consciousness recovered to Japan Coma Scale score of 30 and Glasgow Coma Scale score of E2V4M5. CT showed obvious reduction of the hematoma without brain or scalp swelling. Spinal MR imaging detected no redistribution of hematoma to the spine. The present case illustrates that rapid spontaneous reduction of ASDH may occur by redistribution of hematoma, mainly to the supratentorial subdural space because of brain atrophy.

    To describe 5 pediatric patients with traumatic orbital subperiosteal hematoma and review the relevant literature. Retrospective chart analysis of 5 children with posttraumatic subperiosteal hematoma and a systematic review of the English language literature. Five new pediatric cases of orbital subperiosteal hematoma are presented with varying clinical and radiologic manifestations and treatments. Literature review (including the current 5 cases) yielded 23 cases in total. Eighteen (78%) of the patients were boys, and 5 (22%) were girls. The children ranged in age from 5 to 17 years, with the mean and median ages being 12 years. The leading cause was blunt trauma related to falls or direct impact. Two patients (9%) had an inherited coagulopathy, predisposing them to orbital hemorrhage. The hematomas developed in the superior orbit in all cases except one. In 3 patients (13%), orbital hematomas were bilateral. In 9 patients (39%), the hematomas extended in subgaleal or frontal subdural spaces. In 7 patients (30%), subperiosteal hematoma was associated with compressive optic neuropathy. Four patients (17%) had a nondisplaced orbital roof fracture. Seventeen patients were treated with surgical evacuation of hematoma (52%) or with needle aspiration (22%), and 5 patients (22%) were observed for spontaneous resolution. Three patients (13%) experienced a recurrence of hemorrhage. In children, traumatic subperiosteal hematomas of the orbit typically occur after blunt trauma in the superior orbit. The risk of compressive optic neuropathy may be higher in patients with bilateral hematoma and massive subgaleal hematoma. Most patients are treated with evacuation of the hematoma.

    We endeavored to analyze patients of subacute and chronic subdural hematomas studied in a 4-year period at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, India. The study was a retrospective analysis of 1181 patients of subdural hematomas. Demographic characteristics, clinico-radiologic features, operative modalities, and outcome were studied. Acute subdural hematomas were excluded from the study. The mean age was 60.4 ± 12.4 and males outnumbered females. Chronic subdural collections were more common than subacute subdural hematomas and left side predominated. Two burr holes with closed-system drainage was used in most patients. Incidence of postoperative seizures is very low. Overall recurrence rates were low; however, multilocular hematomas had the highest incidence of recurrence. Morbidity and mortality were 7.53% and 2.96%, respectively. Preoperative neurologic grade correlated with outcome. Subdural hematomas are common in elderly males. Preoperative neurologic grade dictates the outcome. Multilocular hematomas have a higher chance of recurrence. Craniotomy should be reserved for recurrent hematomas, and there may be a scope of craniotomy for multilocular chronic subdural hematomas at the outset. Antiepileptic prophylaxis is not routinely recommended. Copyright © 2012 Elsevier Inc. All rights reserved.

    Introduction: This study reports a rare patient of a rapid spontaneously resolving acute subdural hematoma. In addition, an analysis of potential clues for the phenomenon is presented with a review of the literature. Patient Presentation: A 1-year-and-2-month-old boy fell from a height of approximately 2 m. The patient was in a superficial coma with a Glasgow Coma Scale of 8 when he was transferred to the authors’ hospital. Computed tomography revealed the presence of an acute subdural hematoma with a midline shift beyond 1 cm. His guardians refused invasive interventions and chose conservative treatment. Repeat imaging after 15 hours showed the evident resolution of the hematoma and midline reversion. Progressive magnetic resonance imaging demonstrated the complete resolution of the hematoma, without redistribution to a remote site. Conclusions: Even though this phenomenon has a low incidence, the probability of a rapid spontaneously resolving acute subdural hematoma should be considered when patients present with the following characteristics: children or elderly individuals suffering from mild to moderate head trauma; stable or rapidly recovered consciousness; and simple acute subdural hematoma with a moderate thickness and a particularly low-density band in computed tomography scans.

    The hepatic hematoma or rupture appear in 1 of every 100,000 pregnancies. The most common causes of hepatic hematoma in pregnancy are severe preeclampsia and HELLP syndrome; some predisposing factors are seizures, vomiting, labor, preexistent hepatic disease and trauma. A 33 year old primigravid with a normal 33 week twin pregnancy presented abdominal pain and hypovolemic shock due to spontaneous subcapsular hepatic hematoma; laparoscopy was performed to evaluate the possibility of rupture, which was not found, later emergency cesarean section was carried out followed by hepatic hematoma drainage and abdominal packaging by laparoscopy. After surgery the flow through drainage was too high additionally hemodynamic instability and consumption coagulopathy. Abdominal panangiography was performed without identifying bleeding areas. Intesive care was given to the patient evolving satisfactorily, was discharged 19 days after the event. Seven months later she had laparoscopic cholecystectomy due to acute litiasic colecistitis. We found 5 cases in literatura about hepatic hematoma during pregnancy no related to hypertensive disorders of pregnancy; these were related to hepatoma, amebian hepatic abscess, falciform cell anemia, cocaine consumption and molar pregnancy. Hepatics hematomas have high morbidity and mortality so is significant early diagnosis and multidisciplinary approach.

    In clinical forensic medicine, the estimation of the age of injuries such as externally visible subcutaneous hematomas is important for the reconstruction of violent events, particularly to include or exclude potential suspects. Since the estimation of the time of origin based on external inspection is unreliable, the aim of this study was to use contrast in MRI to develop an easy-to-use model for hematoma age estimation. In a longitudinal study, artificially created subcutaneous hematomas were repetitively imaged using MRI over a period of two weeks. The hemorrhages were created by injecting autologous blood into the subcutaneous tissue of the thigh in 20 healthy volunteers. For MRI, standard commercially available sequences, namely proton-density-weighted, T2 -weighted and inversion recovery sequences, were used. The hematomas' MRI data were analyzed regarding their contrast behavior using the most suitable sequences to derive a model allowing an objective estimation of the age of soft tissue hematomas. The Michelson contrast between hematoma and muscle in the proton-density-weighted sequence showed an exponentially decreasing behavior with a dynamic range of 0.6 and a maximum standard deviation of 0.1. The contrast of the inversion recovery sequences showed increasing characteristics and was hypointense for TI = 200ms and hyperintense for TI =1000ms. These sequences were used to create a contrast model. The cross-validation of the model finally yielded limits of agreement for hematoma age determination (corresponding to ±1.96 SD) of ±38.7h during the first three days and ±54 h for the entire investigation period. The developed model provides lookup tables which allow for the estimation of a hematoma's age given a single contrast measurement applicable by a radiologist or a forensic physician. This is a first step towards an accurate and objective dating method for subcutaneous hematomas, which will be particularly useful in child abuse. Copyright © 2014 John

    Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists.

    A 79-year-old lean man with a height of 157cm and weight of 42kg (body mass index, 17.2kg/m(2)) receiving rivaroxaban developed an intracranial subdural hematoma and was treated conservatively. Because he had a reduced creatinine clearance of 44mL/min, his dosage of rivaroxaban was reduced from 15 to 10mg daily according to official Japanese prescribing information. However, he developed bilateral intracranial subdural hematomas 2weeks later. Plasma rivaroxaban concentration on anti-factor Xa chromogenic assay was elevated at 301ng/mL, suggesting excessive accumulation. He underwent burr hole drainage and resumed anticoagulation with warfarin. Subsequently, he developed a lumbosacral hematoma. He was treated conservatively and discharged without neurological sequelae. The main cause of the increased concentration of rivaroxaban was believed to be his older age and low body weight. The etiology of the spinal hematoma was suspected to be the migration of intracranial hematoma to the spinal subdural space. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Inflammation and the coagulation system may influence the genesis of chronic subdural hematoma (CSDH). The appearance of CSDH on computed tomography (CT) varies with the stage of the hematoma. This study investigated the pathogenesis and the recurrence of CSDH by comparing cytokine levels with the CT features of CSDH in 26 patients with 34 CSDHs who underwent single burr-hole surgery at our hospital between October 2004 and November 2006. The hematoma components removed during the procedure were examined, and the hematoma serum levels of cytokines measured such as thrombomodulin (TM), interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), and interleukin-10 (IL-10). Using CT, mixed density hematomas were distinguished from other homogeneous hematomas, and found that the TM level was significantly higher in mixed density hematomas than in homogeneous hematomas (p = 0.043). Mixed density hematomas were classified into three subtypes (laminar, separated, and trabecular hematomas). The TM level was significantly higher in laminar and separated hematomas than in other hematomas (p = 0.01). The levels of IL-6, TNFα, and IL-10 were extremely high, but showed no significant differences in relation to the CT features. Mixed density hematomas had high recurrence rate, as reported previously, and TM level was high in mixed density hematomas such as laminar and separated mixed density hematomas. The present findings suggest that the types of CSDH associated with high TM levels tend to have higher recurrence rate.

    Chronic subdural hematoma is characterized by blood in the subdural space that evokes an inflammatory reaction. Numerous factors potentially associated with recurrence of chronic subdural hematoma have been reported, but these factors have not been sufficiently investigated. In this study, we evaluated the independent risk factors of recurrence. We analyzed data for 420 patients with chronic subdural hematoma treated by the standard surgical procedure for hematoma evacuation at our institution. Ninety-two (21.9 %) patients experienced at least one recurrence of chronic subdural hematoma during the study period. We did not identify any significant differences between chronic subdural hematoma recurrence and current antiplatelet therapy. The recurrence rate was 7 % for the homogeneous type, 21 % for the laminar type, 38 % for the separated type, and 0 % for the trabecular type. The rate of recurrence was significantly lower in the homogeneous and trabecular type than in the laminar and separated type. We performed a multivariate logistic regression analysis and found that postoperative midline shifting (OR, 3.6; 95 % CI, 1.618-7.885; p = 0.001), diabetes mellitus (OR, 2.2; 95 % CI, 1.196-3.856; p = 0.010), history of seizure (OR, 2.6; 95 % CI, 1.210-5.430; p = 0.014), width of hematoma (OR, 2.1; 95 % CI, 1.287-3.538; p = 0.003), and anticoagulant therapy (OR, 2.7; 95 % CI, 1.424-6.960; p = 0.005) were independent risk factors for the recurrence of chronic subdural hematoma. We have shown that postoperative midline shifting (≥5 mm), diabetes mellitus, preoperative seizure, preoperative width of hematoma (≥20 mm), and anticoagulant therapy were independent predictors of the recurrence of chronic subdural hematoma. According to internal architecture of hematoma, the rate of recurrence was significantly lower in the homogeneous and the trabecular type than the laminar and separated type.

    Traumatic spinal subdural hematoma is rare and its mechanism remains unclear. This intervention describes a patient with mental retardation who was suffering from back pain and progressive weakness of the lower limbs following a traffic accident. Magnetic resonance imaging of the spine revealed a lumbar subdural lesion. Hematoma was identified in the spinal subdural space during an operation. The muscle power of both lower limbs recovered to normal after surgery. The isolated traumatic spinal subdural hematoma was not associated with intracranial subdural hemorrhage. A spinal subdural hematoma should be considered in the differential diagnosis of spinal cord compression, especially for patients who have sustained spinal trauma. Emergency surgical decompression is usually the optimal treatment for a spinal subdural hematoma with acute deterioration and severe neurological deficits. Copyright © 2011.

    Objective: To determine the association of ultraearly hematoma growth (uHG) with the CT angiography (CTA) spot sign, hematoma expansion, and clinical outcomes in patients with acute intracerebral hemorrhage (ICH). Methods: We analyzed data from 231 patients enrolled in the multicenter Predicting Haematoma Growth and Outcome in Intracerebral Haemorrhage Using Contrast Bolus CT study. uHG was defined as baseline ICH volume/onset-to-CT time (mL/h). The spot sign was used as marker of active hemorrhage. Outcome parameters included significant hematoma expansion (>33% or >6 mL, primary outcome), rate of hematoma expansion, early neurologic deterioration, 90-day mortality, and poor outcome. Results: uHG was higher in spot sign patients (p < 0.001) and in patients scanned earlier (p < 0.001). Both uHG >4.7 mL/h (p = 0.002) and the CTA spot sign (p = 0.030) showed effects on rate of hematoma expansion but not its interaction (2-way analysis of variance, p = 0.477). uHG >4.7 mL/h improved the sensitivity of the spot sign in the prediction of significant hematoma expansion (73.9% vs 46.4%), early neurologic deterioration (67.6% vs 35.3%), 90-day mortality (81.6% vs 44.9%), and poor outcome (72.8% vs 29.8%), respectively. uHG was independently related to significant hematoma expansion (odds ratio 1.06, 95% confidence interval 1.03–1.10) and clinical outcomes. Conclusions: uHG is a useful predictor of hematoma expansion and poor clinical outcomes in patients with acute ICH. The combination of high uHG and the spot sign is associated with a higher rate of hematoma expansion, highlighting the need for very fast treatment in ICH patients. PMID:27343067

    We evaluated the incidence and predisposing factors of groin hematomas after electrophysiological (EP) procedures. Prospective, observational study, enrolling consecutive patients after EP procedures (Atrial fibrillation: n = 151; Supraventricular tachycardia/Diagnostic EP: n = 82; Ventricular tachycardia: n = 18). Patients underwent manual compression for 10 min and 3 h post procedural bed rest. AF ablations were performed with INR 2-3, ACT > 300, and no protamine sulfate. Adhesive pressure dressings (APDs) were used if sheath size ≥ 10F; procedural time > 120 min; and BMI > 30. Patient-reported hematomas were recorded by a telephone follow-up after 2 weeks. Hematoma developed immediately in 26 patients (10%) and after 14 days significant hematoma was reported in 68 patients (27%). Regression analysis on sex, age, BMI 25, ACT 300, use of APD, sheath size and number, and complicated venous access was not associated with hematoma, either immediately after the procedure or after 14 days. Any hematoma presenting immediately after procedures was associated with patient-reported hematomas after 14 days, odds ratio 18.7 (CI 95%: 5.00-69.8; P < 0.001). Any hematoma immediately after EP procedures was the sole predictor of patient-reported hematoma after 2 weeks. Initiatives to prevent groin hematoma should focus on the procedure itself as well as post-procedural care.

    Objective Although twist-drill craniostomy (TDC) has a number of procedural advantages and an equivalent outcome compared to burr hole craniostomy (BHC) for the treatment of chronic subdural hematomas (CSDHs), the latter technique remains the preferred method. We analyzed symptomatic CSDHs in whom TDC at the pre-coronal suture entry point (PCSEP) was the primary method for hematoma drainage and BHC on the parietal was the secondary option. Methods CSDHs in 86 consecutive patients were included. TDC at the PCSEP, which is 1 cm anterior to coronal suture at the level of the superior temporal line, was the primary operational technique when the hematoma thickness was suitable, and BHC was performed via the parietal when TDC was unreasonable or failed. The clinical feasibility and outcomes of these approaches were analyzed. Results Of the 86 patients, 68 (79.1%) were treated by TDC, and 18 (20.9%) by BHC. All patients showed improvements in their symptoms after hematoma drainage. Neither morbidity nor mortality was associated with either technique, and there were no differences in drainage days between the groups. Ten patients had bilateral hematomas and were treated using TDC. Two patients were not sufficiently treated by TDC and, as a result, BHC was applied. Only six hematomas (7% of 86 hematomas) exhibited insufficient thickness on the computed tomography to perform TDC. Conclusion When the hematoma was thick enough, a majority of the CSDHs were drained using TDC at the PCSEP as the first procedure, which was especially useful for bilateral hematomas and in elderly patients.

    The Microwave Hematoma Detector is a non-invasive device designed to detect and localize blood pooling and clots near the outer surface of the body. While being geared towards finding sub-dural and epi-dural hematomas, the device can be used to detect blood pooling anywhere near the surface of the body. Modified versions of the device can also detect pneumothorax, organ hemorrhage, atherosclerotic plaque in the carotid arteries, evaluate perfusion (blood flow) at or near the body surface, body tissue damage at or near the surface (especially for burn assessment) and be used in a number of NDE applications. The device is based on low power pulsed microwave technology combined with a specialized antenna, signal processing/recognition algorithms and a disposable cap worn by the patient which will facilitate accurate mapping of the brain and proper function of the instrument. The invention may be used for rapid, non-invasive detection of sub-dural or epi-dural hematoma in human or animal patients, detection of hemorrhage within approximately 5 cm of the outer surface anywhere on a patient's body.

    Hematoma surrounding an implant is one of the many factors that have been suggested as possible causes for scar capsule contracture. In this study, experiments were designed to determine the influence of hematoma on the incidence and severity of capsule contracture in rabbits. Two implants were placed in each animal, 1 with a surrounding hematoma and 1 control. Capsules were evaluated subjectively and compared objectively with measurements of deformability, surface area, and capsule thickness. No differences were found with any of the objective criteria, which suggests that hematoma may not be a noteworthy cause of implant capsule contracture.

    The purpose of the study was to evaluate if IV contrast extravasation on CT in anticoagulant-related rectus sheath and iliopsoas hematoma predict hematoma expansion and patient outcomes. All patients presented with anticoagulation-related spontaneous IP hematoma or RS hematoma and who underwent contrast-enhanced CT exploration, with injection of a contrast material, from January 2012 to January 2015 in our institution were included in this study. Considering the retrospective nature of our study, our institutional review board judged our study to be exempted from ethical approval and no patient consent was required. Computed tomography (CT) images were retrospectively analyzed blindly of the evolution and treatment of hematomas. The type of muscle involved; the presence of contrast extravasation after contrast injection; the volume of the hematoma, as well as, clinical and biological results (hemoglobin value g/dL); and for each patient, the type of anticoagulation used, patient's treatment and outcomes were noted. The analyses were conducted using R 3.1.0. All statistical tests were 2-sided, and probability values <0.05 were regarded as significant. Sixty-eight patients were reviewed. Among 68 patients, 44 (65%) patients presented spontaneous IP hematoma and 24/68 (35%) a RS hematoma. There were 37 men (54%) and 31 (46%) women, ranging from 39 to 93 years with a median age of 75 years. Hemodynamic instability was statistically associated with IP hematomas and large volume of hematoma (p < 0.001). Only 15 patients had follow-up CT, 10 without and with IV contrast, 2 with IV contrast only, and 3 without contrast. Follow-up CT was performed from J0 to J8. Detection of contrast extravasation did not appear related to hemodynamically instability (p = 0.35), to a neurological deficit (p = 1), or to the increase in the volume of the hematoma on follow-up CT (p = 0.81). The different types of anticoagulant were not related to muscular type more than the other

    Apixaban is an oral anticoagulant that directly inhibits Factor Xa and is indicated for the prophylaxis and treatment of deep venous thrombosis and stroke prevention in non-valvular atrial fibrillation. Rectus sheath hematoma is a rare, life-threatening complication of anticoagulant treatment. We describe a case of an elderly patient on apixaban for the treatment of deep venous thrombosis who developed severe abdominal pain during hospitalization. Computed tomography of the abdomen revealed left rectus sheath hematoma. Apixaban was discontinued and the patient was monitored for extension of the hematoma. After 2 days she was discharged home. Outpatient computed tomography 1 month later showed complete resolution of the rectus sheath hematoma. We recommend that clinicians become aware of the potential for rare and serious bleeding complications of anticoagulants and identify the need for early recognition and prompt management.

    The correlation between hematoma volume and outcome in ruptured arteriovenous malformations (AVM) with accompanying posterior fossa hematoma was retrospectively evaluated. Microsurgery operations were performed on 127 patients with intracranial AVM between January 1998 and January 2009 at our clinic. Fifteen (11.8%) patients were identified as suffering from posterior fossa AVM, and twelve of these patients presented with a cerebellar hematoma. All patients were clinically evaluated according to the following criteria: modified Rankin Scale (mRS) prior to surgery, Spetzler-Martin grade (SMG) of the AVMs, hematoma volume prior to surgery, and mRS following surgery. Postoperative mRS scores were significantly lower than preoperative scores (p=0.0001). Postoperative outcomes were concordant with the SMG of the AVMs (r=0.67, p=0.033), hematoma volume (r=0.537, p=0.072) and preoperative mRS scores (r=0.764, p=0.004). These analyses show that the postoperative mRS score is strongly correlated with a preoperative mRS score, hematoma volume and SMG. Posterior fossa AVMs present an increased risk for hemorrhage and for increased morbidity and mortality. Cases with hematoma should be operated on an urgent basis. We conclude that hematoma volume is a factor that impacts postoperative results and prognosis. SMG and preoperative mRS scores were also correlated with outcome.

    A 70-year-old man, who had previously undergone surgical resection of left parasagittal meningioma involving the middle third of the superior sagittal sinus (SSS) two times, presented with recurrence of the tumor. We performed removal of the tumor combined with SSS resection as Simpson grade II. After tumor removal, since a left dominant bilateral chronic subdural hematoma (CSDH) appeared, it was treated by burr hole surgery. However, because the CSDH rapidly and repeatedly recurred and eventually changed to acute subdural hematoma, elimination of the hematoma with craniotomy was accomplished. The patient unfortunately died of worsening of general condition despite aggressive treatment. Histopathology of brain autopsy showed invasion of anaplastic meningioma cells spreading to the whole outer membrane of the subdural hematoma. Subdural hematoma is less commonly associated with meningioma. Our case indicates the possibility that subdural hematoma associated with meningioma is formed by a different mechanism from those reported previously. PMID:29896565

    Objective: To summarize our experience with the surgical treatment of traumatic multiple intracranial hematomas (TMIHs) and discuss the surgical indications. Methods: We analyzed the clinical data of 118 patients with TMIHs who were treated at the West China Hospital in Sichuan University, Chengdu, China between October 2008 and October 2011, including age, gender, cause of injury, diagnosis, treatment, and outcomes. Results: Among the 118 patients, there were 12 patients with different types of hematomas at the same site, 69 with one hematoma type in different compartments, and 37 with different types of hematomas in different compartments. In total, 106 patients had obliteration of basal cisterns, and 34 had a simultaneous midline shift ≥5 mm. Eighty-nine patients underwent single-site surgery, 19 had 2-site surgeries, and 10 patients did not undergo surgery. Based on the Glasgow Outcome Scale 6 months post-injury, 41 patients had favorable outcomes, and 77 had unfavorable outcomes. Basal cisterns obliteration was a strong indicator for surgical treatment. Single- or 2-site surgery was not related to outcome (p=0.234). Conclusion: Obliteration of the basal cisterns is a strong indication for surgical treatment of TMIHs. After evacuation of the major hematomas, the remaining hematomas can be treated conservatively. Most patients only require single-site surgical treatment. PMID:25274591

    Ear disease, such as otitis externa, resulting in aggressive head shaking or ear scratching, is the most common cause of the development of aural hematomas in dogs and cats. An underlying immunologic cause has also been proposed to explain cartilage and blood vessel fragility. Numerous options exist for management of aural hematomas, from medical management alone with corticosteroids, to simple hematoma centesis, to surgical intervention. Because this condition is usually secondary to another disease process, regardless of mode of treatment, likelihood of recurrence is low if the underlying condition is managed properly.

    Summary Characterization of hematomas is essential in scan reading, manual delineation, and designing automatic segmentation algorithms. Our purpose is to characterize the distribution of intraventricular (IVH) and intracerebral hematomas (ICH) in NCCT scans, study their relationship to gray matter (GM), and to introduce a new tool for quantitative hematoma delineation. We used 289 serial retrospective scans of 51 patients. Hematomas were manually delineated in a two-stage process. Hematoma contours generated in the first stage were quantified and enhanced in the second stage. Delineation was based on new quantitative rules and hematoma profiling, and assisted by a dedicated tool superimposing quantitative information on scans with 3D hematoma display. The tool provides: density maps (40-85HU), contrast maps (8/15HU), mean horizontal/vertical contrasts for hematoma contours, and hematoma contours below a specified mean contrast (8HU). White matter (WM) and GM were segmented automatically. IVH/ICH on serial NCCT is characterized by 59.0HU mean, 60.0HU median, 11.6HU standard deviation, 23.9HU mean contrast, –0.99HU/day slope, and –0.24 skewness (changing over time from negative to positive). Its 0.1st-99.9th percentile range corresponds to 25-88HU range. WM and GM are highly correlated (R 2=0.88; p<10–10) whereas the GM-GS correlation is weak (R 2=0.14; p<10–10). The intersection point of mean GM-hematoma density distributions is at 55.6±5.8HU with the corresponding GM/hematoma percentiles of 88th/40th. Objective characterization of IVH/ICH and stating the rules quantitatively will aid raters to delineate hematomas more robustly and facilitate designing algorithms for automatic hematoma segmentation. Our two-stage process is general and potentially applicable to delineate other pathologies on various modalities more robustly and quantitatively. PMID:24976197

    91 patients with acute head injuries, hydrocephalus, cerebral infarction, subarachnoid hemorrhage, encephalitis, intracerebral hemorrhage, or carbon monoxide intoxication have been so monitored by using the Numoto pressure switch by a method herein described. The main advantage has been the knowledge of the level of intracranial pressure at any given time and the early detection of a rising pressure when this phenomenon occurred. There were no complications except for 3 cases of infection. Two of these cases were minor purulent collections only at the site of exit of the tube in the scalp. One patient with a compound wound, cerebral laceration, and intracerebral hematoma developed a wound infection and brain abscess which required drainage.

    In clinical forensic medicine, hematomas and other externally visible injuries build the basis for the reconstruction of events. However, dating of subcutaneous hematomas based on their external aspect is difficult. Magnetic resonance imaging (MRI) has proven its use in dating intracranial hemorrhage. Thus, the aim was to investigate if MRI can also be used for dating subcutaneous hematomas and to analyze an eventual influence of the hematoma shape. In 20 healthy volunteers (11 females, 9 males, aged 26.9 ± 3.8 years), 4 ml of autologous blood were injected subcutaneously in the thigh. The hematoma was scanned immediately after the injection, after 3 and 24 h and 3, 7, and 14 days using three sequences with different contrast. Data was analyzed by measuring signal intensities of the hematoma, the muscle, and the subcutaneous tissue over time, and the Michelson contrast coefficients between the tissues were calculated. In the analysis, hematoma shape was considered. Signal intensity of blood in the proton density-weighted sequence reached its maximum 3 h after the injection with a subsequent decrease, whereas the signal intensities of muscle and fatty tissue remained constant. The time course of the Michelson coefficient of blood versus muscle decreased exponentially with a change from hyperintensity to hypointensity at 116.9 h, depending on hematoma shape. In the other sequences, either variability was large or contrast coefficients stayed constant over time. The observed change of contrast of blood versus muscle permits a quick estimate of a hematoma's age. The consideration of the hematoma shape is expected to further enhance dating using MRI.

    Chronic subdural hematoma (CSDH) is a common disease in the elderly, and the recurrence rate of CSDH is reported to range from 2.3 to 33%. We performed a retrospective review of a number of CSDH cases and the potential factors associated with CSDH recurrence. The patient population comprised 112 men and 65 women with a mean age of 74.7 years. We analyzed the following factors: age, sex, antiplatelet and anticoagulant use, hematoma laterality, hematoma thickness, degree of midline shift and internal architecture of the hematoma in the preoperative CT films, use of irrigation, direction of the drainage tube, width of the subdural space, and degree of midline shift and the presence of a massive subdural air collection in the postoperative CT films. Univariate analysis revealed that there was a trend for different rates of recurrence among the different types of hematomas. The presence of a postoperative massive subdural air collection tended to be associated with the recurrence of hematoma. Multivariate analysis revealed that separated hematomas were significantly associated with CSDH recurrence, whereas the presence of postoperative massive subdural air collection tended to be associated with hematoma recurrence. Neither univariate nor multivariate analysis could demonstrate an association between the direction of the drainage tube and the recurrence of CSDH.

    A 73-year-old man was admitted to our clinic with sudden left quadrant abdominal pain and hematochezia. There was no history of trauma. He denied other symptoms or taking off-the-counter medication. His medical history was relevant for ischemic and aortic-mitral valve disease with prosthetic valves for which he was medicated with aspirin and warfarin. On physical examination the patient presented normal vital signs with tenderness on palpation of the left side of the abdomen. Laboratory tests revealed moderate anemia (10.8 g/dl) and thrombocytopenia (135.000x10^9 U/L) with therapeutic international normalized ratio (2.53). Colonoscopy revealed an extensive area of erythematous and bluish mucosa with an apparent torsion of the proximal descending colon around a volumous hematoma measuring 6.5x3 cm (Figure 1 A-C). Urgent abdominal CT confirmed the presence of a large intramural hematoma of the descending colon (Figure 2 A-B). A conservative approach was adopted with temporary suspension of anticoagulation. Given the high thrombotic risk, abdominal ultrasound was performed after 72 hours showing considerable reduction in the size of the hematoma. Anti-coagulation was then resumed without complications. One month later, colonoscopy was repeated showing complete healing of the mucosa. The increasing use of anti-aggregating and anti-coagulant therapy, especially in elderly patients, explains the increasing incidence of bleeding events seen in this population. However, gastrointestinal hematomas are estimated to occur in only 1 for every 250.000 anti-coagulated patients. Diagnosis is based on characteristic radiologic findings. While most parietal hematomas can be approached conservatively, surgery is indicated in the presence of complications or persistence of the hematoma.

    The objectives of our study were to describe the pathology of ear hematomas in swine and to add to the comprehension of the pathogenesis of this condition. The pathogenesis of aural hematomas has been studied mainly in dogs; however, disagreements exist about the precise anatomic location of the hemorrhage. Sixteen pigs with ear hematoma at various stages of development were included in this study. The pigs were submitted for routine autopsy for various and unrelated reasons over a period of several years. Based on gross examination, the 16 cases of aural hematomas were subjectively classified as acute (n = 6), subacute (n = 3), and chronic (n = 7). The age of the animals at the time of autopsy ranged from 2 weeks to adulthood, with all acute cases being <7 weeks of age. Morphologic examination of all acute cases revealed that the hematoma developed predominantly in a subperichondral location on both sides of the cartilaginous plate simultaneously. Within these same cases, there were also some areas in which blood-filled clefts had formed within the cartilage itself. Besides fibroplasia, neoformation of cartilage was found to represent a significant part of the repair process. All chronic cases were characterized on cross-section of the ear by the presence of at least 2 distinct, wavy, focally folded, and roughly parallel plates of cartilage separated from each other by fibrous tissue. © 2016 The Author(s).

    This study aims to describe the unique characteristics of absorption fever in patients with a hematoma after percutaneous renal biopsy (PRB) and distinguish it from secondary infection of hematoma.We retrospectively studied 2639 percutaneous renal biopsies of native kidneys. We compared the clinical characteristics between 2 groups: complication group (gross hematuria and/or perirenal hematoma) and no complication group. The axillary temperature of patients with a hematoma who presented with fever was measured at 06:00, 10:00, 14:00, and 18:00. The onset and duration of fever and the highest body temperature were recorded. Thereafter, we described the time distribution of absorption fever and obtained the curve of fever pattern.Of 2639 patients, PRB complications were observed in 154 (5.8%) patients. Perirenal hematoma was the most common complication, which occurred in 118 (4.5%) of biopsies, including 74 small hematoma cases (thickness ≤3 cm) and 44 large hematoma cases (thickness >3 cm). Major complications were observed in only 6 (0.2%) cases resulting from a large hematoma. Of 118 patients with a perirenal hematoma, absorption fever was observed in 48 cases. Furthermore, large hematomas had a 5.23-fold higher risk for absorption fever than the small ones.Blood pressure, renal insufficiency, and prothrombin time could be risk factors for complications. Fever is common in patients with hematoma because of renal biopsy and is usually noninfectious. Evaluation of patients with post-biopsy fever is necessary to identify any obvious infection sources. If no focus is identified, empiric antibiotic therapy should not be initiated nor should prophylactic antibiotics be extended for prolonged durations. Absorption fevers will resolve in time without specific therapeutic interventions.

    To determine the clinical implications of acute pelvicaliceal hematoma formation during percutaneous catheter nephrostomy (PCN) insertion. Collecting system hematoma burden was retrospectively assessed for 694 PCN insertions in 502 patients. Pelvicaliceal hematoma formation occurred in 146 kidneys (21%) in 136 patients. Clinically significant blood loss occurred in 3 patients with hematomas within one week compared to 4 patients without hematomas (p=0.39). Twenty-four patients with hematomas underwent catheter exchange within one week, compared to 55 patients without hematomas (p=0.49). Pelvicaliceal hematoma formation after PCN insertion is not uncommon and is associated with very rare clinical sequelae. Copyright © 2017 Elsevier Inc. All rights reserved.

    To study the prognoses of patients with subdural hematoma (SDH) who were not operated on at the time of the first diagnosis and the causes of enlarged hematomas in some patients during the follow-up period. The records, service files, and radiologic examination results of the patients with diagnoses of SDH were reviewed. The SDH patients were recorded under 5 different categories: acute SDH (ASDH), subacute SDH (SSDH), chronic SDH (CSDH), acute component with chronic SDH (A-CSDH), and subacute component with chronic SDH (S-CSDH). The symptoms, clinical findings, and progression in the patients were correlated with radiologic examinations. A total of 291 patients received diagnoses of SDHs: 80 patients with acute, 29 patients with subacute, and 163 patients with chronic hematoma. Thirty-five patients had diagnoses of SDH with a combination of different components. It was determined that in the follow-up period, patients with A-CSDH showed the greatest increase in hematoma size over time and required surgical intervention the most often. SDHs reveal different prognoses in different age groups. Multicomponent SDHs are within the group that shows the greatest increase in size in the follow-up period. SDHs and CSDHs cause recurrent hemorrhages by sustaining the tension on the bridging veins. The greater the hematoma volume, the greater the growth potential of the hematoma tends to be. CSDHs that do not manifest changes in volume for a long time can be monitored without surgical intervention as long as the clinical picture remains stable. Copyright © 2018 Elsevier Inc.

    Duodenal hematomas from blunt abdominal trauma are uncommon in children and treatment strategies vary. We reviewed our experience with this injury at a large-volume children's hospital. A retrospective case series was assembled from January 2003-July 2014. Data collected included demographics, clinical and radiographic characteristics, and hospital course. Patients with grade I injuries based on the American Association for the Surgery of Trauma Duodenum Injury Scale were compared with those with grade II injuries. Nineteen patients met inclusion criteria at a median age of 8.91 y (range, 1.7-17.2 y). Mechanisms of injury included direct abdominal blow or handle bar injury (n = 9), nonaccidental trauma (n = 5), falls (n = 3), and motor vehicle accident (n = 2). Ten patients had grade I hematomas and nine had grade II. Hematomas were most frequently seen in the second portion of the duodenum (n = 9). Five patients underwent a laparotomy for concerns for hollow viscus injury. No patients required operative drainage of the hematoma; however, one patient underwent percutaneous drainage. Twelve patients received parenteral nutrition (PN) for a median duration of 9 d (range, 5-14 d). Median duration of PN for grade I was 6.5 d (range, 5-8 d) versus 12 d for grade II (range, 9-14 d; P = 0.016). Complications included one readmission for concern of bowel obstruction requiring bowel rest. This study suggests that duodenal hematomas can be successfully managed nonoperatively. Grade II hematomas are associated with longer duration of PN therapy and consequently longer hospital stays. These data can assist in care management planning and parental counseling for patients with traumatic duodenal hematomas. Copyright © 2015 Elsevier Inc. All rights reserved.

    A low-cost, time-efficient technique that could localize hypertensive hematomas in the basal ganglia would be beneficial for minimally invasive hematoma evacuation surgery. We used an iPhone to achieve this goal and evaluated its accuracy and feasibility. We located basal ganglia hematomas in 26 patients and depicted the boundaries of the hematomas on the skin. To verify the accuracy of the drawn boundaries, computed tomography (CT) markers surrounding the depicted boundaries were attached to 10 patients. The deviation between the CT markers and the actual hematoma boundaries was then measured. In the other 16 patients, minimally invasive endoscopic hematoma evacuation surgery was performed according to the depicted hematoma boundary. The deflection angle of the actual trajectory and deviation in the hematoma center were measured according to the preoperative and postoperative CT data. There were 40 CT markers placed on 10 patients. The mean deviation of these markers was 3.1 mm ± 2.4. In the 16 patients who received surgery, the deflection angle of the actual trajectory was 4.3° ± 2.1. The deviation in the hematoma center was 5.2 mm ± 2.6. This new method can locate basal ganglia hematomas with a sufficient level of accuracy and is helpful for minimally invasive endoscopic hematoma evacuation surgery. Copyright © 2016 Elsevier Inc.

    Paravaginal hematomas can be life-threatening. In patients with intact vaginal walls and perineum, they may pose a diagnostic and therapeutic challenge. Supralevator hematomas are much less common than infralevator hematomas. We present a case of puerperal hemorrhagic shock after a normal vaginal delivery in a low-risk parous woman resulting from an occult supralevator hematoma. Because the woman was hemodynamically unstable initially, she underwent a vaginal surgical drainage. A week later, the supravaginal hematoma reformed. At this time the patient was hemodynamically stable, and ultrasound-guided drainage was performed, which resulted in complete resolution of the hematoma within 10 days. In a clinically stable puerperal patient, ultrasound-guided drainage of a supralevator hematoma resulted in rapid and complete resolution of symptoms.

    Intrauterine hematomas are a common pregnancy complication. The literature lacks studies about outcomes based on hematoma localization. Thus, we aimed to compare pregnancies complicated by an intraplacental hematoma to cases with a retroplacental hematoma and to a control group. In a retrospective case-control study, 32 women with an intraplacental hematoma, 199 women with a retroplacental hematoma, and a control group consisting of 113 age-matched women with no signs of placental abnormalities were included. Main outcome measures were pregnancy complications. Second-trimester miscarriage was most common in the intraplacental hematoma group (9.4%), followed by women with a retroplacental hematoma (4.2%), and controls (0%; p = 0.007). The intraplacental hematoma group revealed the highest rates for placental insufficiency, intrauterine growth retardation, premature preterm rupture of membranes, preterm labor, preterm delivery <37 weeks, and early preterm delivery <34 weeks (p < 0.05), followed by the retroplacental hematoma group. When tested in multivariate models, intraplacental hematomas were independent predictors for placental insufficiency (ß = 4.19, p < 0.001) and intrauterine growth restriction (ß = 1.44, p = 0.035). Intrauterine fetal deaths occurred only in women with a retroplacental hematoma (p = 0.042). Intra- and retroplacental hematomas have different risk profiles for the affected pregnancy and act as independent risk factors.

    Acute epidural hematoma is a critical emergency all around the world, and its aggressive diagnosis and treatment are of vital importance. Emergent surgical evacuation of the hematoma is known as standard management; however, conservative procedures are also used for small ones. Spontaneous rapid resolution of these hematomas has also been reported in eight pediatric cases. Various theories have been proposed to explain the underlying pathophysiology of this resolution. Herein, we are reporting a new pediatric case with spontaneously resolving acute epidural hematoma 12 hours after admission to the emergency room. PMID:24489555

    Intra- and extra-muscular hematomas result from repetitive injury as well as sharp and blunt limb trauma. The clinical consequences can be serious, including debilitating pain and functional deficit. There are currently no short-term treatment options for large hematomas, only lengthy conservative treatment. The goal of this work was to evaluate the feasibility of a high intensity focused ultrasound (HIFU)-based technique, termed histotripsy, for rapid (within a clinically relevant timeframe of 15–20 min) liquefaction of large volume (up to 20 mL) extra-vascular hematomas for subsequent fine-needle aspiration. Experiments were performed using in vitro extravascular hematoma phantoms—fresh bovine blood poured into 50 mL molds and allowed to clot. The resulting phantoms were treated by boiling histotripsy (BH), cavitation histotripsy (CH) or a combination in a degassed water tank under ultrasound guidance. Two different transducers operating at 1 MHz and 1.5 MHz with f-number = 1 were used. The liquefied lysate was aspirated and analyzed by histology and sized in a Coulter Counter. The peak instantaneous power to achieve BH was lower than (at 1.5 MHz) or equal to (at 1 MHz) that which was required to initiate CH. Under the same exposure duration, BH-induced cavities were one and a half to two times larger than the CH-induced cavities, but the CH-induced cavities were more regularly shaped, facilitating easier aspiration. The lysates contained a small amount of debris larger than 70 μm, and 99% of particulates were smaller than 10 μm. A combination treatment of BH (for initial debulking) and CH (for liquefaction of small residual fragments) yielded 20 mL of lysate within 17.5 minutes of treatment and was found to be most optimal for liquefaction of large extravascular hematomas.

    2015-01-01

    "Headbanging" is the slang term used to denote violent shaking of one's head in time with the music. This abrupt flexion-extension movement of the head to rock music extremely rarely causes a subdural hematoma. A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity. She had no history of recent head trauma but performed headbanging at a punk rock concert at 3 days before admission. Since, she had a previous acute subdural hematoma on the same side after an accidental fall from a baby buggy when she was 11 months old, the present was recurrent subdural hematoma probably due to headbanging. Headbanging has the hazardous potential to cause a subdural hematoma.

    Management guidelines for single intracranial hematomas have been established, but the optimal management of multiple hematomas has little known. We present bilateral traumatic supratentorial hematomas that each has enough volume to be evacuated and discuss how to operate effectively it in a single anesthesia. In total, 203 patients underwent evacuation and/or decompressive craniectomies for acute intracranial hematomas over 5 years. Among them, only eight cases (3.9%) underwent operations for bilateral intracranial hematomas in a single session. Injury mechanism, initial Glasgow Coma Scale score, types of intracranial lesions, surgical methods, and Glasgow outcome scale were evaluated. The most common injury mechanism was a fall (four cases). The types of intracranial lesions were epidural hematoma (EDH)/intracerebral hematoma (ICH) in five, EDH/EDH in one, EDH/subdural hematoma (SDH) in one, and ICH/SDH in one. All cases except one had an EDH. The EDH was addressed first in all cases. Then, the evacuation of the ICH was performed through a small craniotomy or burr hole. All patients except one survived. Bilateral intracranial hematomas that should be removed in a single-session operation are rare. Epidural hematomas almost always occur in these cases and should be removed first to prevent the hematoma from growing during the surgery. Then, the other hematoma, contralateral to the EDH, can be evacuated with a small craniotomy.

    Objective Management guidelines for single intracranial hematomas have been established, but the optimal management of multiple hematomas has little known. We present bilateral traumatic supratentorial hematomas that each has enough volume to be evacuated and discuss how to operate effectively it in a single anesthesia. Methods In total, 203 patients underwent evacuation and/or decompressive craniectomies for acute intracranial hematomas over 5 years. Among them, only eight cases (3.9%) underwent operations for bilateral intracranial hematomas in a single session. Injury mechanism, initial Glasgow Coma Scale score, types of intracranial lesions, surgical methods, and Glasgow outcome scale were evaluated. Results The most common injury mechanism was a fall (four cases). The types of intracranial lesions were epidural hematoma (EDH)/intracerebral hematoma (ICH) in five, EDH/EDH in one, EDH/subdural hematoma (SDH) in one, and ICH/SDH in one. All cases except one had an EDH. The EDH was addressed first in all cases. Then, the evacuation of the ICH was performed through a small craniotomy or burr hole. All patients except one survived. Conclusion Bilateral intracranial hematomas that should be removed in a single-session operation are rare. Epidural hematomas almost always occur in these cases and should be removed first to prevent the hematoma from growing during the surgery. Then, the other hematoma, contralateral to the EDH, can be evacuated with a small craniotomy. PMID:25237431

    Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

    From 1991 until 2013, 304 patients with intracranial hematomas from aneurysmal rupture were managed surgically in our department, constituting 17 % of all patients with aneurysmal rupture. Of them, 242 patents presented with isolated intracerebral hematomas (in 69 cases associated with significant intraventricular hemorrhage), 50 patients presented with combined intracerebral and subdural hematomas (in 11 cases associated with significant intraventricular hemorrhage), and 12 presented with an isolated subdural hematoma. The surgical procedure consisted of simultaneous clipping of the aneurysm and evacuation of the hematoma in all cases. After surgery, 16 patients (5 %) submitted to an additional decompressive hemicraniectomy, and 66 patients (21 %) submitted to a ventriculo-peritoneal shunt. Clinical outcomes were assessed at discharge and at 6 months, using the modified Rankin Scale (mRS); a favorable outcome (mRS 0-2) was observed in 10 % of the cases at discharge, increasing to 31 % at 6 months; 6-month mortality was 40 %. Applying uni- and multivariate analysis, the following risk factors were associated with a significantly worse outcome: age >60; preoperative Hunt-Hess grades IV-V; pupillary mydriasis (only on univariate); midline shift >10 mm; hematoma volume >30 cc; and the presence of hemocephalus (i.e., packed intraventricular hemorrhage). Based on these results, an aggressive surgical treatment should be adopted for most cases with aneurysmal hematomas, excluding patients with bilateral mydriasis persisting after rescue therapy.

    Abstract Rationale: Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. Patient concerns: A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. Diagnoses: CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Interventions: Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. Outcomes: His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Lessons: Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury. PMID:29879068

    Objective The objectives of the present study were to characterize the natural course of initially non-operated traumatic acute subdural hematoma (ASDH) and to identify the risk factors of hematoma progression. Methods Retrospective analysis was performed using sequential computed tomography (CT) images maintained in a prospective observational database containing 177 ASDH cases treated from 2005 to 2011. Patients were allocated to four groups as followings; 136 (76.8%) patients to the spontaneous resolution group, 12 (6.8%) who underwent operation between 4 hours and 7 days to the rapid worsening group (RWG), 24 (13.6%) who experienced an increase of hematoma and that underwent operation between 7 and 28 days to the subacute worsening group (SWG), and 5 (2.8%) who developed delayed aggravation requiring surgery from one month after onset to the delayed worsening group (DWG). Groups were compared with respect to various factors. Results No significant intergroup difference was found with respect to age, mechanism of injury, or initial Glasgow Coma Scale. The presence of combined cerebral contusion or subarachnoid hemorrhage was found to be a significant prognostic factor. Regarding CT findings, mixed density was common in the RWG and the SWG. Midline shifting, hematoma thickness, and numbers of CT slices containing hematoma were significant prognostic factors of the RWG and the SWG. Brain atrophy was more severe in the SWG and the DWG. Conclusion A large proportion of initially non-operated ASDHs worsen in the acute or subacute phase. Patients with risk factors should be monitored carefully for progression by repeat CT imaging.

    A puerperal vulvovaginal hematoma may continue to grow after a surgical procedure and may require blood transfusion. Thus, we selected arterial embolization for hemostasis as the first-line management in two cases of large vulvovaginal hematoma. Case 1 was a 32-year-old pregnant woman. After delivery, a 10-cm vulvar hematoma developed. An enhanced computed tomography (CT) scan revealed active bleeding. Arterial embolization was performed and complete hemostasis was obtained. Case 2 was a 34-year-old woman with a recurring hematoma after delivery. An enhanced CT scan revealed extravasation in the hematoma. Gelatin sponges were applied and complete hemostasis was obtained. In both cases, arterial embolization was successful without requiring blood transfusions. We successfully managed two cases of puerperal vulvovaginal hematoma by arterial embolization based on the evaluation of an enhanced CT scan. In conclusion, we suggest arterial embolization to be a viable option for first-line treatment in the management of vulvovaginal hematomas. Copyright © 2017. Published by Elsevier B.V.

    The aim of the study is to evaluate the efficacy of craniotomy and membranectomy as initial treatment of organized chronic subdural hematoma (OCSH). We retrospectively reviewed a series of 34 consecutive patients suffering from OCSH, diagnosed by magnetic resonance imaging (MRI) or contrast computer tomography (CCT) in order to establish the degree of organization and determine the intrahematomal architecture. The indication to perform a primary enlarged craniotomy as initial treatment for non-liquefied chronic subdural hematoma (CSDH) with multilayer loculations was based on the hematoma MRI appearance—mostly hyperintense in both T1- and T2-weighted images with a hypointense web- or net-like structure within the hematoma cavity. The reason why some hematomas evolve towards a complex and organized architecture remains unclear; the most common aspect to come to light was the “long standing” of the CSDHs which, in our series, had an average interval of 10 weeks between head injury and initial scan. Recurrence was found to have occurred in 2 patients (6% of cases) in the form of acute subdural hematoma. One patient died as the result of an intraventricular and subarachnoid haemorrhage, while 2 patients (6%) suffered an haemorrhagic stroke ipsilateral to the OCSH. Eighty-nine percent of cases had a good recovery, while 11% remained unchanged or worsened. In select cases, based on the MRI appearance, primary enlarged craniotomy seems to be the treatment of choice for achieving a complete recovery and a reduced recurrence rate in OCSH. PMID:24305027

    Intra- and extra-muscular hematomas result from repetitive injury as well as sharp and blunt limb trauma. The clinical consequences can be serious, including debilitating pain and functional deficit. There are currently no short-term treatment options for large hematomas, only lengthy conservative treatment. The goal of this work was to evaluate the feasibility of a high intensity focused ultrasound (HIFU)-based technique, termed histotripsy, for rapid (within a clinically relevant timeframe of 15-20 min) liquefaction of large volume (up to 20 mL) extra-vascular hematomas for subsequent fine-needle aspiration. Experiments were performed using in vitro extravascular hematoma phantoms-fresh bovine blood poured into 50 mL molds and allowed to clot. The resulting phantoms were treated by boiling histotripsy (BH), cavitation histotripsy (CH) or a combination in a degassed water tank under ultrasound guidance. Two different transducers operating at 1 MHz and 1.5 MHz with f-number = 1 were used. The liquefied lysate was aspirated and analyzed by histology and sized in a Coulter Counter. The peak instantaneous power to achieve BH was lower than (at 1.5 MHz) or equal to (at 1 MHz) that which was required to initiate CH. Under the same exposure duration, BH-induced cavities were one and a half to two times larger than the CH-induced cavities, but the CH-induced cavities were more regularly shaped, facilitating easier aspiration. The lysates contained a small amount of debris larger than 70 μm, and 99% of particulates were smaller than 10 μm. A combination treatment of BH (for initial debulking) and CH (for liquefaction of small residual fragments) yielded 20 mL of lysate within 17.5 minutes of treatment and was found to be most optimal for liquefaction of large extravascular hematomas.

    Chronic subdural hematoma (CSDH) is a common neurosurgical problem. Most studies of pathogenesis and treatment involve humans. Advances in understanding of human diseases may be made using animal models. We reviewed all animal models of CSDH and report here their results, conclusions and limitations in order to set a baseline upon which further advanced experimental work related to this disease can be made. PubMed, Medline, Embase and ISI Web of Knowledge were searched with no time limits using the keyword 'chronic subdural hematoma' and MeSH term 'hematoma, subdural, chronic'. The authors reviewed all papers written related to this disease and selected all publications involving animals. There were no other restrictions. The findings and conclusions of the papers are summarized here. No formal analysis was done because of the variation in species used, methods for induction of CSDH, times of assessment and reporting of results. Attempts to create CSDH have been made in mice, rats, cats, dogs and monkeys. Methods include injection or surgical implantation of clotted blood or various other blood products and mixtures into the potential subdural space or the subcutaneous space. No intracranial model produced a progressively expanding CSDH. Transient hematoma expansion with liquification could be produced by subcutaneous injections in some models. Spontaneous subdural blood collections were found after creation of hydrocephalus in mice by systemic injection of the neurotoxin, 6-aminonicotinamide. The histology of the hematoma membranes in several models resembles the appearance in humans. None of the models has been replicated since its first description. We did not find a report of a reproducible, well-described animal model of human CSDH.

    Arachnoid cysts are well known to induce chronic subdural hematoma (CSDH) after head injury. However, histological observations of the arachnoid cyst and hematoma membrane have only been rarely described. An 8-year-old boy and a 3-year-old boy presented with CSDH associated with arachnoid cyst. Surgical removal of the hematoma and biopsy of the hematoma membrane and cyst wall were performed. Clinical courses were good and without recurrence more than 1.5 years after surgery. Histological examination suggested that the cysts did not contribute to hematoma development. Pediatric hematoma membranes, similar to adult hematoma membranes, are key in the growth of CSDH. Therefore, simple hematoma evacuation is adequate as a first operation for CSDH associated with arachnoid cyst.

Forty cases of various intracranial hematomas were measured by the computer tomography with quantitative software and personal computer with Photoshop CS3 software, respectively. the data from the 2 methods were analyzed and compared. There was no difference between the data from the computer tomography and the personal computer (P>0.05). The personal computer with Photoshop CS3 software can measure the volume of various intracranial hematomas precisely, rapidly and simply. It should be recommended in the clinical medicolegal identification.

    Postoperative hematoma is a rare and dangerous complication of cervical spine surgery. The aim of this study was to investigate the incidence and related factors of postoperative hematoma, and to report on 15 cases at our institution over a 6-year period. Fifteen cases of postoperative hematoma were retrospectively identified. We investigated their neurological outcomes, characteristics, and surgical data, and identified risk factors associated with postoperative (PO) hematoma. Patients with hematoma were compared to those with no hematoma, in order to identify risk factors. Retropharyngeal hematomas developed in seven cases and epidural hematomas in eight. The total incidence of postoperative hematoma was 1.2%: 0.5% retropharyngeal hematomas and 0.6% spinal epidural hematomas. At time of onset, the severity of paralysis was assessed as grade B in one case, grade C in six cases, and grade D in eight cases. Risk factors for PO hematoma were: (1) presence of ossification of the posterior longitudinal ligament (OPLL) (P<0.001); (2) longer operative duration (P=0.048); (3) greater number of surgical levels (P=0.02); and (4) higher body mass index (BMI; P=0.035). There was no significant difference in modified Japan Orthopedic Association scores between the hematoma group and non-hematoma group (P>0.05). Precise preoperative preparation and systematic evaluation are central to successful management of PO hematoma after anterior cervical surgery. Risk factors for PO hematoma include multilevel decompression, OPLL, higher BMI, and longer operation time. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

  5. Chronic expanding hematoma in the retroperitoneal space: a case report

    PubMed Central

    2013-01-01

    Background Chronic expanding hematoma is a rare condition that develops after surgery, trauma, or injury. It can also develop at any location in the body in the absence of trauma. Clinical findings and various diagnostic imaging modalities can aid in the differential diagnosis of this condition. In general, hematomas are naturally reabsorbed and rarely cause serious problems. However, hematomas that develop slowly without a history of trauma, surgery, or bleeding disorders could be difficult to differentiate from soft tissue neoplasms. In the present case, we describe a patient, without any history or physical evidence of trauma, who exhibited a large chronic expanding hematoma in the retroperitoneal space that resulted in hydronephrosis because of the pressure exerted on the left ureter. Case presentation A 69-year-old man presented to our hospital with a swollen lesion in the left flank. A mass, 19 cm in diameter, was detected in the retroperitoneal space by computed tomography. We suspected the presence of a chronic expanding hematoma, soft tissue tumor, or left renal artery aneurysm. Surgical treatment was performed. However, postoperative histopathological examination indicated that the mass was a nonmalignant chronic expanding hematoma. No recurrence was observed during a 2-year follow-up period. Conclusion In patients without a history of trauma who present slowly growing masses, the differential diagnosis should include chronic expanding hematoma in addition to cysts and soft tissue tumors. Moreover, the use of magnetic resonance imaging and computed tomography is essential to differentiate between chronic expanding hematoma and soft tissue tumors. PMID:24237992

    Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24 h after symptom onset, but predominantly occurs in the early hours. Thus capturing markers of on-going bleeding on imaging techniques could predict hematoma expansion. The spot sign observed on computed tomography angiography is believed to represent on-going bleeding and is to date the most well investigated and reliable radiological predictor of hematoma expansion as well as functional outcome and mortality. On non-contrast CT, the presence of foci of hypoattenuation within the hematoma along with the hematoma-size is reported to be predictive of hematoma expansion and outcome. Because patients tend to arrive earlier to the hospital, a larger fraction of acute ICH-patients must be expected to undergo hematoma expansion. This renders observation and radiological follow-up investigations increasingly relevant. Transcranial duplex sonography has in recent years proven to be able to estimate hematoma volume with good precision and could be a valuable tool in bedside serial observation of acute ICH-patients. Future studies will elucidate, if better prediction and observation of post-admission hematoma expansion can help select patients, who will benefit from hemostatic treatment. PMID:25324825

    Introduction Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. Case presentation We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. Conclusion Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

    Retrospective review of prospective database. To investigate risk factors involved in the development of anterior cervical hematomas and determine any impact on patient outcomes. Postoperative (PO) hematomas after anterior cervical spine surgery require urgent recognition and treatment to avoid catastrophic patient morbidity or death. Current studies of PO hematomas are limited. Cervical spine surgical procedures performed on adults by the senior author at a single academic institution from 1995 to 2012 were evaluated. Demographic data, surgical history, operative data, complications, and neck disability index (NDI) scores were recorded prospectively. Cases complicated by PO hematoma were reviewed, and time until hematoma development and surgical evacuation were determined. Patients who developed a hematoma (HT group) were compared with those that did not (no-HT group) to identify risk factors. NDI outcomes were compared at early (<11 mo) and late (>11 mo) time points. There were 2375 anterior cervical spine surgical procedures performed with 17 occurrences (0.7%) of PO hematoma. In 11 patients (65%) the hematoma occurred within 24 hours PO, whereas 6 patients (35%) presented at an average of 6 days postoperatively. All underwent hematoma evacuation, with 2 patients (12%) requiring emergent cricothyroidotomy. Risk factors for hematoma were found to be (1) the presence of diffuse idiopathic skeletal hyperostosis (relative risk = 13.2, 95% confidence interval = 3.2-54.4), (2) presence of ossification of the posterior longitudinal ligament (relative risk = 6.8, 95% confidence interval = 2.3-20.6), (3) therapeutic heparin use (relative risk 148.8, 95% confidence interval = 91.3-242.5), (4) longer operative time, and (5) greater number of surgical levels. The occurrence of a PO hematoma was not found to have a significant impact on either early (HT: 30, no-HT: 28; P = 0.86) or late average NDI scores (HT: 28, no-HT 31; P = 0.76). With fast recognition and treatment, no

    Acute auricular hematoma is common after blunt trauma to the side of the head. A network of vessels provides a rich blood supply to the ear, and the ear cartilage receives its nutrients from the overlying perichondrium. Prompt management of hematoma includes drainage and prevention of reaccumulation. If left untreated, an auricular hematoma can result in complications such as perichondritis, infection, and necrosis. Cauliflower ear may result from long-standing loss of blood supply to the ear cartilage and formation of neocartilage from disrupted perichondrium. Management of cauliflower ear involves excision of deformed cartilage and reshaping of the auricle. © Thieme Medical Publishers.

    The purpose of this study was to compare hematoma formation after breast core needle biopsy performed on patients undergoing and those not undergoing concurrent antithrombotic therapy. A prospective assessment of core needle biopsies (stereotactic, ultrasound guided, or MRI guided) performed on patients enrolled between September 2011 and July 2012 formed the basis of this study. Postprocedure mediolateral and craniocaudal mammograms were evaluated for the presence and size of hematomas. Patients were clinically evaluated for complications 24-48 hours after the procedure through telephone call or face-to-face consultation. Needle size, type of biopsy, and presence of hematoma and documented complications were correlated with use of antithrombotic agents (including aspirin, warfarin, clopidogrel, and daily nonsteroidal antiinflammatory medications). No clinically significant hematomas or bleeding complications were found. Eighty-nine of 617 (14.4%) non-clinically significant hematomas were detected on postprocedure mammograms. The probability of development of a non-clinically significant hematoma was 21.6% for patients taking antithrombotics and 13.0% for those not taking antithrombotics. Concurrent antithrombotic therapy and larger needle gauge were significant factors contributing to the probability of hematoma formation. The volume of the hematoma was not related to needle gauge or presence of antithrombotic therapy. No clinically significant hematomas were found. Because there are potential life-threatening risks to stopping antithrombotic therapy before breast biopsy, withholding antithrombotic therapy for core needle breast biopsy is not recommended because the incidence of non-clinically significant hematoma is low.

    Hematomas may develop in the postoperative setting after free tissue transfer. When hematomas occur, they can exert pressure on surrounding tissues. Their effect on the vascular pedicle of a free flap is unknown. We describe our incidence of hematoma in free flaps and outcomes when the flap is compromised. Retrospective chart review of 1,883 free flaps performed between July 1998 and June 2014 at a tertiary referral center. Patients with free flap compromise due to hematoma were identified. Etiology, demographic data, and outcomes were evaluated. Eighty-eight (4.7%) patients developed hematomas. Twenty (22.7%) of those had flap compromise. Twelve compromises (60%) showed evidence of pedicle thrombosis. The salvage rate was 75% versus 54% in 79 flaps with compromise from other causes (P = .12). Mean time to detection of the hematoma was 35.3 hours in salvaged flaps compared to 91.6 hours in unsalvageable flaps (P = .057). Time to operating room (OR) from detection was 2.8 hours in salvageable flaps compared to 12.4 hours in nonsalvageable flaps (P = .053). The salvage rate for flaps that returned to the OR in <5 hours was 93.3% compared to 20% (P = .0049) for those that did not. Vascular thrombosis reduced salvage rate to 58.3% from 100% (P = .002) when there was no thrombosis. In our series hematomas developed rarely. When they did, 23% went on to develop flap compromise. Prompt recognition and re-exploration allowed for a high salvage rate. Vessel thrombosis predicted inability to salvage the flap. 4 © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    A recent report on computed tomography (CT) findings of contrast extravasation in subarachnoid hemorrhage (SAH) with Sylvian hematoma suggests that the occurrence of the hematoma is secondary to bleeding in the subpial space. Our patient was in his sixties and was admitted to the hospital because of loss of consciousness (Glasgow Coma Scale E4V1M4). SAH was diagnosed in plain head CT, and growing hematomas were observed in the Sylvian and interhemispheric fissures following a subarachnoid hemorrhage. CT angiography (CTA) using a dual-phase scan protocol revealed contrast extravasation in both the fissures in the latter phase, and hematoma in the interhemispheric fissure contained multiple bleeding points. This case indicates that the occurrence of subpial hematoma such as Sylvian hematoma can be a secondary event following subpial bleeding from damaged small vessels elsewhere in the cranium. Instead of four-dimensional (4D) CT, the dual-phase CTA technique may help detect minor extravasations with usual helical CT scanner. PMID:25963159

    Traumatic acute subdural hematomas over the convexity of the cerebral hemispheres are often encountered, but acute interhemispheric subdural hematomas are rare. Fourty-eight cases of acute subdural hematomas was admitted to our hospital between 1977 and 1986, and three cases of them (6%) were located in the interhemispheric subdural space. In this paper, these three cases are reported with 20 documented cases. Case 1: an 81-year-old female was admitted to our hospital because of headache, nausea and vomiting. She hit her occiput a week ago. CT scan demonstrated contusion in the right frontal lobe and a high density in the interhemispheric space of the right frontal region. Her complaints disappeared gradually by conservative therapy and she returned to her social life. Case 2: a 50-year-old male fell downstairs and hit his vertex. As he lost consciousness, he was admitted to our hospital. He was stuporous and had left-hemiparesis. Skull X-ray film showed fracture line extending from the right temporal bone to the left parietal bone across the midline. CT scan revealed intracerebral hematoma in both frontal lobe and right parietal lobe and subarachnoid hemorrhage in the basal cistern and Sylvian fissure of the right side. And interhemispheric subdural hematoma in the right parietal region was visualized. Angiography demonstrated a lateral displacement of the right callosomarginal artery and an avascular area between the falx and the callosomarginal artery. After admission his consciousness recovered and convulsion was controlled by drug. Left-hemiparesis was improved by conservative therapy and he was discharged on foot.(ABSTRACT TRUNCATED AT 250 WORDS)

    For intramural hematoma and penetrating atherosclerotic ulcer, long-term behavior and treatment are controversial. This study evaluates the long-term behavior of intramural hematoma and penetrating atherosclerotic ulcer, including radiologic follow-up and survival analysis. Between 1995 and 2014, 108 patients (mean age, 70.8 ± 10 years; 56% female) presented with intramural hematoma or penetrating atherosclerotic ulcer to Yale-New Haven Hospital (New Haven, Conn). We reviewed the medical records, radiology, and online mortality databases. Ten of 55 patients (18%) with intramural hematoma and 17 of 53 patients (32%) with penetrating atherosclerotic ulcer had rupture state symptoms on admission, both greater than type A (8%) or type B dissection (4%) (P < .001). No branch vascular occlusion occurred. For patients with intramural hematoma with follow-up imaging, 8 of 14 (57%) worsened (mean follow-up, 9.4 months) and 6 (43%) underwent late surgery. For patients with penetrating atherosclerotic ulcer with follow-up imaging, 6 of 20 (30%) worsened and underwent late surgery, and 11 (55%) showed no change (mean follow-up, 34.3 months). Overall survivals were 77%, 70%, 58%, and 33% at 1, 3, 5, and 10 years, respectively. No operative deaths occurred for patients with nonrupture state. Patients with penetrating atherosclerotic ulcer with initial surgical treatment had better long-term survival than patients treated medically (P = .037). In the intramural hematoma group, no such difference was observed (P = .10). At presentation, the incidence of early rupture of intramural hematoma and penetrating atherosclerotic ulcer was higher than for typical dissection. For branch vessels, intramural hematoma never occludes branch arteries. On imaging follow-up, patients with intramural hematoma and penetrating atherosclerotic ulcer rarely improved, with late surgery commonly needed. Better survival was observed for the initial surgical management of patients with penetrating

    Abstract To identify risk factors for post-thyroidectomy hematoma requiring airway intervention or surgery (“wound hematoma”) and determine post-thyroidectomy time to intervention. Post-thyroidectomy hematoma is rare but potentially lethal. Information on wound hematoma in a nationwide clinical setting is scarce. Using the Japanese Diagnosis Procedure Combination database, we extracted data from records of patients undergoing thyroidectomy from July 2010 to March 2014. Patients with clinical stage IV cancer or those with bilateral neck dissection were excluded because they could have undergone planned tracheotomy on the day of thyroidectomy. We assessed the association between background characteristics and wound hematoma ≤2 days post-thyroidectomy, using multivariable logistic regression analysis. Among 51,968 patients from 880 hospitals, wound hematoma occurred in 920 (1.8%) ≤2 days post-thyroidectomy and in 203 (0.4%) ≥3 days post-thyroidectomy (in-hospital mortality = 0.05%). Factors significantly associated with wound hematoma ≤2 days post-thyroidectomy were male sex (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.30–1.77); higher age (OR 1.01, 95% CI 1.00–1.02); overweight or obese (OR 1.22, 95% CI 1.04–1.44); type of surgery (partial thyroidectomy for benign tumor compared with: total thyroidectomy, benign tumor [OR 1.95, 95% CI 1.45–2.63]; partial thyroidectomy, malignant tumor [OR 1.21, 95% CI 1.00–1.46]; total thyroidectomy, malignant tumor [OR 2.49, 95% CI 1.82–3.49]; and thyroidectomy for Graves disease [OR 3.88, 95% CI 2.59–5.82]); neck dissection (OR, 1.53, 95% CI 1.05–2.23); antithrombotic agents (OR 1.58, 95% CI 1.15–2.17); and blood transfusion (OR 5.33, 95% CI 2.39–11.91). Closer monitoring of airway and neck is recommended for patients with risk factors, and further cautious monitoring beyond 3 days post-thyroidectomy. PMID:26886632

    Among the intracranial hematomas, chronic subdural hematomas (CSDH) are the most benign with a mortality rate of 0.5-4.0%. The elderly and alcoholics are commonly affected by CSDH. Even though high percentage of CSDH patients improves after the evacuation, there are some unexpected potential complications altering the postoperative course with neurological deterioration. Poor outcome in postoperative period is due to complications like failure of brain to re-expand, recurrence of hematoma and tension pneumocephalus. We present a case report with multiple intraparenchymal hemorrhages in various locations like brainstem, cerebral and cerebellar peduncles, right cerebellar hemisphere, right thalamus, right capsulo-ganglionic region, right corona radiata and cerebral hemispheres after CSDH evacuation. Awareness of this potential problem and the immediate use of imaging if the patient does not awake from anesthesia or if he develops new onset focal neurological deficits, are the most important concerns to the early diagnosis of this rare complication.

    To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far. Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4. All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years. This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

    Pocket hematoma is a recognized complication after placement of cardiac implantable electronic devices and is associated with increased device infection, length of hospitalization, and morbidity especially with uninterrupted antiplatelet agents and anticoagulants. We assessed the use of a post-surgical vest to decrease the incidence of pocket hematoma in patients undergoing device implantation with uninterrupted antiplatelet and anticoagulants. In this observational study, a vest was used by 20 consecutive patients who were compared to 20 age-, gender-, procedure-matched patients who received standard care. All patients were continued on antiplatelet and anticoagulants in the perioperative period. The pocket was assessed at post procedure day 0, 2, and 7, respectively. There were no significant differences in the baseline characteristics between both groups. Baseline mean international normalized ratio (INR) was significantly higher in the vest group when compared with the control group (2.7 ± 0.4 vs. 2.2 ± 0.3 = <0.001). The incidence of pocket hematoma was significantly lower in the vest group than the control group (0 vs 30%, p = 0.02) at the end of 7 days. Control group had a total of six hematomas with one patient requiring evacuation and blood transfusion. The vest group had three hematomas on day 2 that resolved by day 7. The risk of moderate or large pocket hematoma is significantly reduced with the use of this vest in high-risk patients undergoing implantable devices on uninterrupted antiplatelet and anticoagulants.

    To demonstrate that the diagnosis of an intracranial subdural hematoma should be considered for patients presenting with acute or delayed symptoms of intracranial pathology following resection of a spinal tumor. We present a case of a 57-year-old woman found to have a chronic subdural hematoma 1 month following resection of a thoracic extramedullary ependymoma. Evacuation of the hematoma through a burr hole relieved the presenting symptoms and signs. Resolution of the hematoma was confirmed with a computed tomography (CT) scan. Headache and other symptoms not referable to spinal pathology should be regarded as a warning sign of an intracranial subdural hematoma, and a CT scan of the head should be obtained. The mechanism of the development of the hematoma may be related to the leakage of cerebrospinal fluid with subsequent intracranial hypotension leading to an expanding subdural space and hemorrhage.

    Anticoagulant-induced spontaneous breast hematoma is a very rare clinical entity with only a few cases reported in the literature so far. We describe a case of a spontaneous breast hematoma in a female patient under combined oral anticoagulant and antiplatelet therapy. Physicians should be aware of this possibility in patients under anticoagulant treatment presenting with sudden onset of breast pain and a palpable mass. Repeat imaging is mandatory until complete clinical and imaging resolution of the hematoma. If an abnormality persists, further investigation is needed to exclude an underlying malignancy.

    This retrospective study of medical records, surgical protocols, patient observation cards, and imaging files of 100 patients treated for subdural hematoma analyzed the type of hematoma, patient age and sex, operative technique, neurological status, cause of injury, duration of hospital stay, mortality rate, and the number of and reasons for reoperations to determine the effects on treatment outcomes. The time between the head injury and onset of neurological symptoms was analyzed versus the type of hematoma determined from computed tomography (CT) scans. Acute hematomas accounted for 38% of the cases, with subacute hematomas representing 20%, and chronic ones accounting for 42%. In trauma patients, the mean time interval between the injury and onset of neurological symptoms was 0.38 days for acute hematomas, 13.8 days for subacute hematomas, and 23.75 days for chronic hematomas. Repeat surgery was carried out in 26% of the cases. Improvement was obtained in 44% of cases, deterioration in 20%, and no change in neurological status in 36%. Timing of the operations was between 15:00 and 23:00 in 45%, between 23:00 and 7:00 in 33%, and between 7:00 and 15:00 in 22%. The classification of hematomas based on CT presentation corresponds to the classification based on the time elapsed between injury and onset of symptoms, and appears to be appropriate and useful in everyday practice. No preceding injury was identified in 31.6% of acute hematomas, 50% of subacute hematomas, and 61.9% of chronic hematomas. Analysis of reoperations indicates that trepanation may be superior to craniotomy as primary surgery for subacute and chronic hematomas. Subdural hematoma surgeries take place at all times of the day, with most carried out outside the usual working hours.

    Infected subdural hematoma(ISH)is a rare disease caused by hematogenous infection of a preexisting subdural hematoma. We report a rare case of ISH accompanied by cerebral infarction. A 76-year-old man who had suffered a closed head injury 3 months before presented fever, headache and left hemiparesis during the medical treatment of acute cholangitis and obstructive jaundice with pancreatic cancer at the department of surgical gastroenterology. At the consultation, computed tomography(CT)scan indicated right chronic subdural hematoma. We performed a burr hole opening surgery on the same day. Abscess and hematoma was aspirated from the subdural space, and methicillin-resistant Staphylococcus aureus(MRSA)was detected in this specimen. Thus the diagnosis of the infected subdural hematoma was confirmed. However, despite the antibiotics therapy, follow-up CT showed a low-density area close to the residual abscess, which suggested cerebral infarction. Cerebral angiography showed a vasospasm at the cortical segment of the right middle cerebral artery near the residual abscess. Eventually we carried out a small craniotomy to evacuate the abscess. Our case showed that prompt surgical treatment is required in case of ISH and the whole hematoma and abscess should be removed as soon as possible with an image diagnosis and an additional surgical operation.

    Cardiac implantable electronic device (CIED) hematomas are associated with many adverse outcomes. We examined the incidence and risk factors associated with hematoma formation post-CIED implantation, and explored the preventative effect of prophylactic pressure bandaging (PPB) in a large tertiary center. 1,091 devices were implanted during October 2011-December 2014. Clinically significant hematomas (CSH) were those that necessitated prolonged admission, including those due to reoperation, and clinically suspicious hematomas were swellings noted by medical/nursing staff. We screened for variables affecting hematoma incidence prior to conducting multivariate logistic regression analyses, one for all hematomas and one for CSH. 61 hematomas were identified (5.6% of patients), with 12 of those clinically significant (1.1% of patients). Factors significantly increasing the odds of developing any hematoma were stage 2 (odds ratio [OR] = 2.93, 95% confidence interval [CI] [1.08-7.94], P = 0.034) and 3 chronic kidney disease (CKD) (OR = 3.39 [1.20-9.56], P = 0.021), unfractionated heparin/therapeutic enoxaparin (OR = 3.15 [1.22-8.14], P = 0.018), and dual antiplatelets-aspirin + clopidogrel (OR = 2.95 [1.14-7.65], P = 0.026) + other combinations. Body Mass index (BMI) 25.0-29.9 (OR 0.52 [0.28-0.98], P = 0.044) and >30 were associated with decreased hematoma risk (OR 0.43 [0.20-0.91], P = 0.028). Factors significant for CSH formation were unfractionated heparin/therapeutic enoxaparin (OR = 9.55 [1.83-49.84], P = 0.007) and aspirin + clopidogrel (OR = 7.19 [1.01-50.91], P = 0.048). PPB nonsignificantly increased the odds of total hematoma development (OR = 1.53 [0.87-2.69], P = 0.135), and reduced CSH (OR = 0.67 [0.18-2.47], P = 0.547). Heparin and dual antiplatelet use remain strong predictors of overall hematoma formation. CKD is a comparatively moderate predictor. BMI > 25 may decrease the risk of hematoma formation. PPB had nonsignificant effects on hematoma development

    Rectus sheath hematoma in the vast number of cases is due to an inferior epigastric artery tear occasionally due to trauma (not considered serious) or alterations in coagulation or use of anticoagulant therapy. It is an unlikely and difficult to diagnose pathology. We present the case of a 61-year-old female patient. The patient presented in emergency service with sudden abdominal pain caused by coughing as a result of an upper respiratory tract infection. The culmination was a spontaneous rectus sheath hematoma. Rectus sheath hematoma is a diagnosis to consider in a previously asymptomatic patient who presents with clinical features of acute pain and appearance of increase of volume in the abdominal wall involving the rectus muscles.

    This report describes 2 cases of spontaneous aortic dissecting hematoma in young Border Collie and Border Collie crossbred dogs. Histology was performed in one of the cases involving an unusual splitting of the elastin present within the wall of the aorta, consistent with elastin dysplasia as described in Marfan syndrome in humans. The first case involved a young purebred Border Collie that died suddenly and the second case involved a Border Collie crossbred dog that died after a 1-month history of seizures. Gross lesions included pericardial tamponade with dissection of the ascending aorta in the former case and thoracic cavity hemorrhage, mediastinal hematoma, and aortic dissection in the latter. Histologic lesions in the case of the Border Collie crossbred dog included a dissecting hematoma of the ascending aorta with elastin dysplasia and right axillary arterial intimal proliferation.

    Introduction The purpose of this study is to provide a controlled trial looking at the risk of paraspinal hematoma formation following extensive paraspinal muscle electromyography. Methods 54 subjects ages 55-80 underwent MRI of the lumbar spine before or shortly after electromyography using the paraspinal mapping technique. A neuroradiologist, blinded to the temporal relationship between the EMG and MRI, reviewed the MRIs to look for hematomas in or around the paraspinal muscles. Results Two MRIs demonstrated definite paraspinal hematomas, while 10 were found to have possible hematomas. All hematomas were < 15 mm, and none were close to any neural structures. There was no relationship between MRI evidence of hematoma and either the timing of the EMG or the use of aspirin or other non-steroidal anti-inflammatory drugs. Discussion Paraspinal electromyography can be considered safe in the general population and those taking non-steroidal anti-inflammatory drugs. PMID:22644875

    The purpose of this study was to assess the sensitivity of ultrasound in evaluating peritransplant hematomas that require surgical evacuation in recipients of kidney transplants. Thirty-four patients who underwent 37 hematoma evacuations underwent ultrasound examinations in the 24 hours before surgical evacuation. The operative reports were evaluated for presence and size of collection, presence of active bleeding at operation, and composition of the hematoma. The clinical findings leading to the ultrasound examination were recorded. Ultrasound examinations were evaluated in consensus by two board-certified and fellowship-trained abdominal radiologists for the presence, size, and echogenicity of the collection; subjective perfusion visualized with color and power Doppler ultrasound; velocities of the renal arteries; and arcuate artery resistive indexes. Ten of the 37 imaged hematomas (27%) had either no or small (< 50 mL) fluid collections on ultrasound examination. With sonographic volumetry, the reported intraoperative volumes were underestimated by 46%. The mean arcuate artery resistive index was 0.82 in the superior pole, 0.81 in the mid pole, and 0.78 in the inferior pole of the kidney. A decrease in hemoglobin level was the most sensitive clinical finding for determining the presence of perigraft hematomas. Our results suggest that gray-scale sonography alone appears to have limited sensitivity in detecting clinically significant peritransplant hematomas and that its use may result in overall underestimates of hematomas.

    Supradiaphragmatic hematoma is a type of hematoma that occurs after transsphenoidal (TS) resection of pituitary adenoma and requires special management. Two patients had symptomatic supradiaphragmatic hematomas after total TS resection of pituitary adenomas in the absence of vascular anomalies. Both patients also had hydrocephalus at the time of diagnosis of the hematoma. The initial endoscopic endonasal inspection showed no subdiaphragmatic bleeding. The hematoma was evacuated via a frontolateral approach after insertion of an external ventricular drain (EVD). The supradiaphragmatic hematoma could be clinically and radiologically distinguished. It presented early with visual deterioration without headache. The patients developed hydrocephalus, which was associated with deterioration of level of consciousness. Radiologically, the hematoma filled the suprasellar space and was associated with the extension of bleeding in the basal cisterns. Recovery was good in both patients. There were no permanent neurologic deficits. The EVD was removed in both patients. One patient required a ventriculoperitoneal shunt because of delayed hydrocephalus. Supradiaphragmatic hematoma can be clinically and radiologically distinguished from other types of hematoma occurring after TS resection of pituitary adenoma. Transcranial surgery should be performed to manage supradiaphragmatic hematoma, when symptomatic. Insertion of an EVD at the time of evacuation is mandatory to relax the brain and to alleviate the hydrocephalus. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hematoma of the graft is a life threatening complication of liver transplantation (LT) and there has been no overt conclusion in the literature about optimal management except in scarcely reported cases. It may be either intrahepatic or subcapsular, then again it may develop spontaneously or following parenchimal injuries or transhepatic percutaneous invasive manoeuvers. In this report we describe a rare case of large spontaneous graft intra- and perihepatic hematoma. A 62 year-old man underwent a whole graft orthotopic liver transplantation (OLT) for decompensated chronic liver disease due to alcoholic cirrhosis. The surgical procedure was uneventful. During the early postoperative course, routine Doppler ultrasound examination and CT-scan revealed an extrahepatic paracaval hematoma, 7 days after transplantation, which was stable and conservatively managed until the 18-th postoperative day, when rapidly expanding intraparenchimal hematoma involving the right hemiliver, several other perihepatic hematomas, significant right pleural effusion and hemorrhagic ascites were described. The patient was successfully treated conservatively (nonsurgically) with slow recovery of the liver allograft and discharged one month later in good general status. Celsius.

A 70-year-old woman comes to our attention with acute abdominal pain and a low hemoglobin level. An unenhanced CT was performed demonstrating a large rectus sheath hematoma. A conservative management was initially established. Despite this therapy, the abdominal pain increased together with a further decrease of hemoglobin values. A CT angiography was then performed, demonstrating an active bleeding within the hematoma and addressing the patient to a rapid percutaneous arterial embolization.

    We present a very rare case of a patient with an infected subdural hematoma due to Propionibacterium acnes. A 63-year-old male complained of dizziness and was admitted to our hospital. He had a history of left chronic subdural hematoma due to a traffic accident, which had been conservatively treated. Physical, neurological and laboratory examinations revealed no definite abnormality. Plain CT scan demonstrated a hypodense crescentic fluid collection over the surface of the left cerebral hemisphere. The patient was diagnosed with chronic subdural hematoma and underwent burr hole surgery three times and selective embolization of the middle meningeal artery, but the lesion easily recurred. Repeated culture examinations of white sedimentation detected P. acnes. Therefore, he underwent craniotomy surgery followed by intravenous administration of antibiotics. The infected subdural hematoma was covered with a thick, yellowish outer membrane, and the large volume of pus and hematoma was removed. However, the lesion recurred again and a low-density area developed in the left frontal lobe. Craniotomy surgery was performed a second time, and two Penrose drainages were put in both the epidural and subdural spaces. Subsequently, the lesions completely resolved and he was discharged without any neurological deficits. Infected subdural hematoma may be refractory to burr hole surgery or craniotomy alone, in which case aggressive treatment with craniotomy and continuous drainage should be indicated before the brain parenchyma suffers irreversible damage.

    Intracranial hemorrhage (ICH) is one of the most serious and lethal complications of anticoagulants with a reported incidence of 5-18.5 %. Computed tomographic (CT) findings, should be carefully studied because early diagnosis and treatment of oral anticoagulant use-associated hematomas are vitally important. In the present study, CT findings of intraparenchymal hematomas associated with anticoagulant and antihypertensive use are presented. This study included 45 patients (25 men, 20 women) under anticoagulant (21 patients) or antihypertensive (24 patients) treatment who had brain CT examinations due to complaints and findings suggesting cerebrovascular disease during July 2010-October 2013 period. CT examinations were performed to determine hematoma volumes and presence of swirl sign, hematocrit effect, mid-line shift effect, and intraventricular extension. The patients were 40-89 years of age. In four cases, a total of 51 intraparenchymal hematomas (42 cerebral, 7 cerebellar and 2 brain stem) were detected in multiple foci. Hematoma volumes varied from 0.09 to 284.00 ml. Swirl sign was observed in 87.5 and 63.0 % of OAC-associated ICHs and non-OAC-associated ICHs, respectively. In addition, hematocrit effect was observed in 41.6 % of OAC-associated and in 3.7 % of non-OAC-associated ICHs. Volume increases were observed in all 19 hematomas where swirl sign was detected, and follow-up CT scanning was conducted. Mortality of OAC-associated ICHs was correlated with initial volumes of hematoma, mid-line shift amount, and intraventricular extension. Detection of hematocrit effect by CT scanning of intracranial hematomas should be cautionary in oral anticoagulant use, while detection of swirl sign should be suggestive of active hemorrhage.

    Hematoma or abscess of the liver ligaments is extremely rare, and hematoma of the falciform ligament has been sporadically reported. We report the case of a 70-year-old female who presented with a three-day history of right upper quadrant abdominal pain, fever and nausea. With a preoperative diagnosis of probable perforated acalculous cholecystitis, the patient underwent emergency surgery. Hematoma of the falciform ligament was found. Wide excision of the falciform ligament including the hematoma with abscess was performed. Although pathology of the falciform ligament is rare, it should be included in the differential diagnosis of acute abdomen, especially in the case of antiaggregant drug usage.

    Summary Brain tumors, hematological diseases and vascular malformations like fistulas or arteriovenous malformations are the most well known causes of non-traumatic subdural hematoma (SDH) 1. Although spontaneous subdural hematoma from ruptured intracranial aneurysm has been reported 2, SDH with non radiographic evidence of subarachnoid hemorrhage is very rare 3,4. Moreover, a patient with acute and bilateral spontaneous subdural hematoma secondary to ruptured left posterior communicating artery aneurysm has not been reported to date. The clinical findings and etiologic mechanisms are discussed. PMID:20569549

    Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury.

    Acute subdural hematoma is a serious complication following traumatic brain injury. Large volume hematomas or those with underlying brain injury can cause mass effect, midline shift, and eventually herniation of the brain. Acute subdural hematomas in the young are associated with high-energy trauma and often have underlying contusions, while acute subdural hematomas in the elderly are associated with minor trauma and an absence of underlying contusions, even though the elderly are more likely to be on anticoagulants or anti-platelet therapy. In the young patients with high impact injuries the hematomas tend to be small and the underlying brain injury and swelling is responsible for the increased intracranial pressure and midline shift. In the elderly, the injuries are low impact (e.g fall from standing), the underlying brain is intact, and the volume of the hematoma itself produces symptoms. In addition the use of anticoagulants and antiplatelet agents in the elderly population has been thought to be a poor prognostic indicator and is considered to be responsible for larger hematomas and poor outcome. When managed conservatively, acute subdural hematomas can sometimes progress to chronic subdural hematoma formation, further enlargement, seizures, and progressive midline shift. Another potential difference in the young and the elderly is brain atrophy, which increases the potential space to accommodate a larger hematoma. It is not known if these two groups differ in other ways that might have implications for treatment or prognosis. In this paper, we investigate the clinical course of 80 patients admitted to our institution with acute subdural hematomas, to identify differences in patients above or below the age of 65 years. The natural progression/resolution of acute subdural hematomas was mapped by measuring volume expansion/regression over time. In this retrospective chart review, we investigated clinical baseline metrics and subsequent volumetric expansion

    Delayed epidural hematoma (DEH) following evacuation of traumatic acute subdural hematoma (ASDH) or acute epidural hematoma (EDH) is a rare but devastating complication, especially when it occurs sequentially in a single patient. A 19-year-old man who developed contralateral DEH following craniotomy for evacuation of a traumatic right-side ASDH and then developed a left-side DEH of the posterior cranial fossa after craniotomy for evacuation of the contralateral DEH. He was immediately returned to the operating room for additional surgeries and his neurological outcome was satisfactory. Although DEH occurring after evacuation of ASDH or acute EDH is a rare event, timely recognition is critical to prognosis.

    A variety of subdural pathologies that may mimic hematomas are reported in the literature. We aimed to identify the atypical clinical and radiologic presentations of subdural masses that may mimic subdural hematomas. A systematic review of MEDLINE and Embase was conducted independently by 2 reviewers to identify articles describing subdural hematoma mimickers. We also present a patient from our institution with a subdural pathology mimicking a subdural hematoma. We analyzed patient clinical presentations, underlying pathologies, radiologic findings, and clinical outcomes. We included 43 articles totaling 48 patients. The mean ± SD patient age was 55.7 ± 16.8 years. Of the 45 cases describing patient history, 13 patients (27%) had a history of trauma. The underlying pathologies of the 48 subdural collections were 10 metastasis (21%), 14 lymphoma (29%), 7 sarcoma (15%), 4 infectious (8%), 4 autoimmune (8%), and 9 miscellaneous (19%). Findings on computed tomography (CT) scan were 18 hyperdense (41%), 11 hypodense (25%), 9 isodense (20%), 3 isodense/hyperdense (7%), and 3 hypodense/isodense (7%). Thirty-four patients (71%) were treated surgically; among these patients, 65% had symptom resolution. Neither the pathology (P = 0.337) nor the management strategy (P = 0.671) was correlated with improved functional outcomes. Identification of atypical history and radiologic features should prompt further diagnostic tests, including magnetic resonance imaging (MRI), to elucidate the proper diagnosis, given that certain pathologies may be managed nonsurgically. A subdural collection that is hyperdense on CT scan and hyperintense on T2-weighted MRI, along with a history of progressive headache with no trauma, may raise the suspicion of an atypical subdural pathology.

    The optimal management of chronic subdural hematomas remains a challenge. Twist drill craniotomy or burr hole trephination are considered optimal initial treatments, but the reoperation rate for hematoma recurrence and other complications is still high. Therefore, evaluation of possible risk factors for initial treatment failure is crucial. In this context, we performed a study to define a possible subpopulation that may benefit from a more invasive initial treatment regime. We retrospectively reviewed the medical charts of 193 patients with 250 chronic subdural hematomas who had undergone burr hole trephination as first-line therapy in our institution between January 2005 and October 2012. To identify risk factors for reoperation, a multivariable logistic regression analysis was performed with reoperation as the dependent variable. Surgical complications, including acute rebleeding, infection and chronic hematoma recurrence, were analyzed separately using a logistic regression model. The mean age of the cohort was 71.4 years. The male/female ratio was 137:56. Reoperation was necessary in 56 cases (29%) for recurrent hematomas and surgical complications. Predictors for reoperation for surgical complications were midline shift (odds ratio [OR] (per mm) 1.16, 95% confidence interval [CI]: 1.05-1.29, p=0.006), arterial hypertension (OR 5.44, 95% CI: 1.45-20.41, p=0.012) and bilateral hematomas (OR 4.22, 95% CI: 1.22-14.58, p=0.023). There was a trend toward a higher risk of surgically-relevant hematoma recurrence in patients with prior treatment with vitamin K antagonists (OR 1.76, 95% CI: 0.75-4.13, p=0.191). Burr hole trephination is the therapy of choice in most chronic subdural hematomas, but the rate of recurrent hematomas is high. Every hematoma should be treated individually especially in relation to midline-shift and pre-existing conditions. Further prospective studies evaluating types of treatment and hematoma density are needed. Copyright © 2015 Elsevier B

    Impact trauma may cause a hematoma, which is the leakage of venous blood into surrounding tissues. Large hematomas can be dangerous as they may inhibit local blood ow. Hematomas are often diagnosed visually, which may be problematic if the hematoma leaks deeper than the visible penetration depth. Furthermore, vascular wound healing is often monitored at home without the aid of a clinician. We therefore investigated the use of near infrared (NIR) re ectance photoplethysmographic imaging (PPGI) to assess vascular damage resulting from a hematoma, and monitor the healing process. In this case study, the participant experienced internal vascular damage in the form of a hematoma. Using a PPGI system with dual-mode temporally coded illumination for ambient-agnostic data acquisition and mounted optical elements, the tissue was illuminated with a spatially uniform irradiance pattern of 850 nm wavelength light for increased tissue penetration and high oxy-to-deoxyhemoglobin absorption ratio. Initial and follow-up PPGI data collection was performed to assess vascular damage and healing. The tissue PPGI sequences were spectrally analyzed, producing spectral maps of the tissue area. Experimental results show that spatial differences in spectral information can be observed around the damaged area. In particular, the damaged site exhibited lower pulsatility than the surrounding healthy tissue. This pulsatility was largely restored in the follow-up data, suggesting that the tissue had undergone vascular healing. These results indicate that hematomas can be assessed and monitored in a non-contact visual manner, and suggests that PPGI can be used for tissue health assessment, with potential extensions to peripheral vascular disease.

    Fracture of the penis is a direct blunt trauma of the erect or semi-erect penis. It can be treated by conservative or surgical means. Retrospective analyses of conservative penile fracture treatment reveal frequent immediate and later complications. We presented a 41-year-old patient with pulsative hematoma caused by an unusual fracture of the penis. Fracture had appeared 40 days before the admittance during a sexual intercourse. The patient was treated surgically. Pulsative hematoma (pulsative diverticulum) is a very rare, early complication of a conservatively treated penile fracture. Surgical treatment has an advantage over surgical one, which was confirmed by our case report.

    Renal subcapsular hematoma is not an uncommon complication after extracorporeal short wave lithotripsy, trauma, renal angiographic procedures and spontaneously in patients of malignancy and in patients on anticoagulation. We present a patient who developed renal subcapsular hematoma after ureterorenoscopy, which has not been mentioned in literature ever. Clinical spectrum varies from spontaneous resolution through acute renal failure to Page kidney. Page kidney is the external compression of a kidney usually caused by a subcapsular hematoma associated with high blood pressure and occasional renal failure. It is named after Dr. Irvin Page who first demonstrated in 1939 that wrapping cellophane tightly around animal kidneys could cause hypertension. Various management options are mentioned in literature and depend upon the severity of hematoma. Percutaneous drainage is a successful option for the management of subcapsular hematoma in hemodynamic stable patients. PMID:20981200

    Spontaneous intracerebral hemorrhages (ICHs) cause significant morbidity and mortality. Traditional open surgical management strategies offer limited benefit except for the most superficial hemorrhages in select patients. Recent reports suggest that endoscopic approaches may improve outcomes, particularly for deep subcortical hemorrhages. However, the management of these patients remains controversial. We reviewed our experience using endoscopic port surgery to identify characteristics that may predict acceptable outcomes. We completed a retrospective chart and imaging review of patients who underwent endoscopic port surgery for evacuation of spontaneous ICH at a single center. Data were gathered regarding patient demographics, hemorrhage locations, operative findings, and clinical outcomes. From 2007 to 2011, 18 patients underwent evacuation of spontaneous intracerebral hematomas using an endoscopic port. The mean age in years was 62 years (range, 43-84 years). Six of 18 patients (33%) died before discharge, and 2 others (11%) died after at least 1 month of survival. Of 12 initial survivors, all were discharged to a rehabilitation or nursing facility. Complete hematoma evacuation was achieved in 7 of 18 patients, with the remaining 11 having a partial evacuation. The patients who died (n = 6) before discharge were statistically more likely to have a left-sided hemorrhage, partial evacuation, or older age than the survivors; death at least 1  month after evacuation was additionally associated with greater preoperative hematoma volumes. Our series demonstrates that endoscopic port surgery for acute intracerebral hematoma evacuation has the ability to achieve significant decompression of large and deep-seated hematomas. Patient age, extent of evacuation, laterality, and preoperative hematoma volume appear to influence patient outcome. Most overall outcomes remain poor. Future studies are necessary to determine if surgical evacuation is in fact superior to best

    Early diagnosis of intracranial hematomas is necessary to improve outcome in patients with traumatic brain injury (TBI). CT and MRI can diagnose intracranial hematomas, but cannot be used until the patient arrives at a major healthcare facility, resulting in delayed diagnosis. Near infrared spectroscopy may suggest the presence of unilateral intracranial hematomas, but provides minimal information on hematoma type and location due to limitations associated with strong light scattering. We have used optoacoustics (which combines high endogenous optical contrast with the resolution of ultrasound) to diagnose hematomas and monitor cerebral oxygenation. We performed animal and clinical studies on detection and characterization of hematomas and on monitoring cerebral hypoxia by probing the superior sagittal sinus (SSS). Recently, we built a medical grade, multi-wavelength, OPO-based optoacoustic system tunable in the near infrared spectral range. We developed new patient interfaces for noninvasive, transcranial measurements in the transmission mode in the presence of dense hair and used it in patients with TBI. The optoacoustic system was capable of detecting and characterizing intra- and extracranial hematomas. SSS blood oxygenation was measured as well with the new interface. The obtained results indicate that the optoacoustic system in the transmission mode provides detection and characterization of hematomas in TBI patients, as well as cerebral venous blood oxygenation monitoring. The transmission mode approach can be used for optoacoustic brain imaging, tomography, and mapping in humans.

    Intralesional injection therapy with OK-432 was developed as a therapy for operatively difficult lymphangioma (cystic hygroma) and is currently becoming a first-choice treatment for this disease. The aim of this article was to evaluate the outcome and complications of the treatment of patients with auricular hematoma by OK-432 therapy. Case series with planned data collection. Yamagata University School of Medicine. We tried this therapy in 21 patients with auricular hematoma between January 2001 and February 2009. We injected OK-432 solution into the lesion with a 27-gauge needle to prevent the leak of the agent out of the hematoma. We performed this treatment on an outpatient basis without hospitalization. Disappearance or marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the auricle did not occur in any patients. As for side effects, local pain at the injection site and fever (37 degrees C-38 degrees C) were observed in a few of the patients who had this therapy, but such problems resolved within a few days. These results may allow us to speculate that intralesional injection therapy with OK-432 is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of auricular hematoma.

    An 81-year-old man presented with gait disturbance. Two months previously, he suffered from hepatocellular carcinoma and transarterial chemoembolization was performed. A head computed tomography(CT)scan revealed bilateral chronic subdural hematomas. The patient's gait disturbance was improved after achievement of bilateral burr hole drainage. A head CT two months after treatment revealed no recurrence of the hematomas. However, head CT images obtained four months after treatment revealed an abnormal mass in the right parietal region attached to the internal surface of the skull. The mass was located in the same region from where the chronic subdural hematomas were previously removed via burr hole drainage, and was suspected to have originated from the dura mater. We performed craniotomy and total removal of the mass. The dura mater was intact, and macroscopically, the mass originated from the organized membrane of the chronic subdural hematoma. A pathological examination revealed metastasis of hepatocellular carcinoma to the membrane of the chronic subdural hematomas. Head magnetic resonance imaging(MRI)performed 39 days after craniotomy presented a new lesion in the left parietal region attached to the internal surface of the skull. The patient subsequently died 46 days post-operation. When examining chronic subdural hematomas in cancer patients, histological examination of the dura mater, hematoma, and membrane of the hematoma are important. The possibility of metastasis to the capsule of the hematoma should be considered.

    A 16-year-old boy collided with a passenger car while riding a motorcycle. He was thrown to a distance and experienced a head injury on impact. When brought to our medical facility, he was alert, had no neurological abnormalities, and did not complain of headache. A head computed tomography(CT)scan indicated a left cranial fracture and an acute epidural hematoma(15mm thick)directly under the fracture. Follow-up head CT performed 3 hours after the injury indicated no change in the size of the hematoma. The head CT performed on the following day indicated that most of the hematoma had disappeared. As the patient had neither headache nor neurological symptoms, he was placed under observation. However, a head CT performed 7 days after the injury indicated the formation of an epidural hematoma approximately the same size as the initial hematoma and located at the same site. We performed craniotomy to evacuate the hematoma, identify the source of the bleeding, and restore hemostasis. Although cases in which an acute epidural hematoma rapidly and spontaneously resolves have been reported, these are extremely rare. Recurrence of an epidural hematoma despite normal blood coagulation function after its initial rapid resolution has not been reported yet. We report on this rare case of acute epidural hematoma with reference to relevant literatures.

    Spontaneous cerebellar intracerebral hemorrhage (ICH) has been reported to be mainly associated with vascular changes secondary to hypertension. However, a subgroup of cerebellar ICH seems related to vascular amyloid deposition (cerebral amyloid angiopathy). We sought to determine whether location of hematoma in the cerebellum (deep and superficial regions) was suggestive of a particular hemorrhage-prone small-vessel disease pathology (cerebral amyloid angiopathy or hypertensive vasculopathy). Consecutive patients with cerebellar ICH from a single tertiary care medical center were recruited. Based on data from pathological reports, patients were divided according to the location of the primary cerebellar hematoma (deep versus superficial). Location of cerebral microbleeds (CMBs; strictly lobar, strictly deep, and mixed CMB) was evaluated on magnetic resonance imaging. One-hundred and eight patients (84%) had a deep cerebellar hematoma, and 20 (16%) a superficial cerebellar hematoma. Hypertension was more prevalent in deep than in patients with superficial cerebellar ICH (89% versus 65%, respectively; P <0.05). Among patients who underwent magnetic resonance imaging, those with superficial cerebellar ICH had higher prevalence of strictly lobar CMB (43%) and lower prevalence of strictly deep or mixed CMB (0%) compared with those with deep superficial cerebellar ICH (6%, 17%, and 38%, respectively). In a multivariable model, presence of strictly lobar CMB was associated with superficial cerebellar ICH (odds ratio, 3.8; 95% confidence interval, 1.5-8.5; P =0.004). Our study showed that superficial cerebellar ICH is related to the presence of strictly lobar CMB-a pathologically proven marker of cerebral amyloid angiopathy. Cerebellar hematoma location may thus help to identify those patients likely to have cerebral amyloid angiopathy pathology. © 2017 American Heart Association, Inc.

    Encapsulated acute subdural hematoma (ASDH) has been uncommonly reported. To our knowledge, a few cases of lentiform ASDH have been reported. The mechanism of encapsulated ASDH has been studied but not completely clarified. Encapsulated lentiform ASDH on a computed tomography (CT) scan mimics acute epidural hematoma (AEDH). Misinterpretation of biconvex-shaped ASDH on CT scan as AEDH often occurs and is usually identified by neurosurgical intervention. We report a case of an 85-year-old man presenting with a 2-day history of mental deterioration and right-sided weakness. CT scan revealed a biconvex-shaped hyperdense mass mixed with various densities of blood along the left temporoparietal cerebral convexity, which was misinterpreted as AEDH preoperatively. Emergency craniectomy was performed, but no AEDH was found beneath the skull. In the subdural space, encapsulated ASDH was located. En block resection of encapsulated ASDH was done. Emergency craniectomy confirmed that the preoperatively diagnosed AEDH was an encapsulated ASDH postoperatively. Radiologic studies of AEDH-like SDH allow us to establish an easy differential diagnosis between AEDH and ASDH by distinct features. More histological studies will provide us information on the mechanism underlying encapsulated ASDH. PMID:27169052

    Extradural hematomas (EDH) are considered life threatening in that the risk for brain herniation is significant. The current accepted understanding within the literature is to treat EDH via surgical evacuation of the hematoma. In this case-series we report 62 cases of EDH managed conservatively without surgical intervention. Inclusion criteria were: Glasgow comma scale score 13-15, extradural hematoma confirmed by CT being less than 40 mm, less than 6 mm of midline shift, and no other surgical lesions present. Patients were initially observed in a surgical intensive care unit prior to discharge and had closely scheduled follow-up. Of the 62 cases none required emergent intervention and the majority had interval resolution of the epidural hematoma over time. Resolution was apparent by 21 days and definitive by 3 to 6 months. Patients with EDH who have a high Glasgow comma scale score 13-15, volume <40 mm, and less than 6 mm of midline shift should be considered for conservative management. Our study indicates that these patients will have interval resolution of hematoma over time without worsening of symptoms.

    This article aims to bring attention to the morbidity and fatality of hemorrhage, how expanding hematoma and air compromise neck/face N/F injuries and present challenges. Large neck vessel ballistic injuries may lead to hemorrhage and expanding hematoma, resulting in airway compromise, due to injuries to the internal and/or external carotid arteries, internal jugular veins "internal carotid artery, external carotid artery, internal jugular vein," and the external carotid artery deep branches. This also leads to injuries to the cervical fascial layers (barriers of deep spaces) that facilitate pooling blood and hematoma into compartmental and large potential space which effects the pharynx, larynx, esophagus, and trachea.The expanding hematomas distort neck anatomical landmarks so "no neck zones" classifications are applicable. As the spectrum of injuries continues to evolve, the clinical characterization needs a new categorization based on compartmental hematoma and potential space anatomical location like retropharyngeal, parapharyngeal, sublingual, submandibular spaces, retrobulbar, and cheek compartment space hematomas.Presence of symptoms and location of the hematoma generally dictate what type of procedure is needed and how urgently it needs to be appropriately performed.Two unusual patients of pseudoaneurysms facial artery injuries with extravasation of blood producing a pulsating hematoma are referred to. Another patient considers large internal carotid artery injuries pseudoaneurysms revealed in angiography.The immediate management of life-saving patients requires aggressive airway maintenance at the scene, conscious victim will often obtain a posture that clears his airway and the semiconscious or unconscious put him in prone position. Air compromise may need emergency intubation, large bore cannula cricothyroidotomy, cricothyrotomy and at medical facilities tracheostomy.

From January 2007 to July 2009, 28 patients underwent percutaneous evacuation. 27 of the 28 patients (96.4%) became asymptomatic or improved clinically. Six weeks later, the scan showed the hematoma had completely disappeared in 18 of the cases. We did not have any postoperative infection. Treatment of chronic subdural hematoma using a percutaneous operative technique is a minimally invasive method with sufficient outcome and a therapeutic alternative to the craniotomy.

    Early hematoma growth is a devastating neurological complication after intracerebral hemorrhage. We aim to report and evaluate the usefulness of computed tomography (CT) black hole sign in predicting hematoma growth in patients with intracerebral hemorrhage. Patients with intracerebral hemorrhage were screened for the presence of CT black hole sign on admission head CT performed within 6 hours after onset of symptoms. The black hole sign was defined as hypoattenuatting area encapsulated within the hyperattenuating hematoma with a clearly defined border. The sensitivity, specificity, and positive and negative predictive values of CT black hole sign in predicting hematoma expansion were calculated. Logistic regression analyses were used to assess the presence of the black hole sign and early hematoma growth. A total of 206 patients were enrolled. Black hole sign was found in 30 (14.6%) of 206 patients on the baseline CT scan. The black hole sign was more common in patients with hematoma growth (31.9%) than those without hematoma growth (5.8%; P<0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of back hole sign in predicting early hematoma growth were 31.9%, 94.1%, 73.3%, and 73.2%, respectively. The time-to-admission CT scan, baseline hematoma volume, and the presence of black hole sign on admission CT independently predict hematoma growth in multivariate model. The CT black hole sign could be used as a simple and easy-to-use predictor for early hematoma growth in patients with intracerebral hemorrhage. © 2016 American Heart Association, Inc.

    Hematoma expansion is independently associated with poor outcome in intracerebral hemorrhage (ICH). Blend sign is a simple predictor for hematoma expansion on non-contrast computed tomography. However, its accuracy for predicting hematoma expansion is inconsistent in previous studies. This meta-analysis is aimed to systematically assess the performance of blend sign in predicting hematoma expansion in ICH. A systematic literature search was conducted. Original studies about predictive accuracy of blend sign for hematoma expansion in ICH were included. Pooled sensitivity, specificity, positive and negative likelihood ratios were calculated. Summary receiver operating characteristics curve was constructed. Publication bias was assessed by Deeks' funnel plot asymmetry test. A total of 5 studies with 2248 patients were included in this meta-analysis. The pooled sensitivity, specificity, positive and negative likelihood ratios of blend sign for predicting hematoma expansion were 0.28, 0.92, 3.4 and 0.78, respectively. The area under the curve (AUC) was 0.85. No significant publication bias was found. This meta-analysis demonstrates that blend sign is a useful predictor with high specificity for hematoma expansion in ICH. Further studies with larger sample size are still necessary to verify the accuracy of blend sign for predicting hematoma expansion. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of this study was to investigate if (1) the volume of subdural hematomas (SDH), midline shift, and CT density of subdural hematomas are altered by postmortem changes and (2) if these changes are dependent on the postmortem interval (PMI). Ante mortem computed tomography (AMCT) of the head was compared to corresponding postmortem CT (PMCT) in 19 adults with SDH. SDH volume, midline shift, and hematoma density were measured on both AMCT and PMCT and their differences assessed using Wilcoxon-Signed Rank Test. Spearman's Rho Test was used to assess significant correlations between the PMI and the alterations of SDH volume, midline shift, and hematoma density. Mean time between last AMCT and PMCT was 109 h, mean PMI was 35 h. On PMCT mean midline displacement was decreased by 57% (p < 0.001); mean SDH volume was decreased by 38% (p < 0.001); and mean hematoma density was increased by 18% (p < 0.001) in comparison to AMCT. There was no correlation between the PMI and the normalization of the midline shift (p = 0.706), the reduction of SDH volume (p = 0.366), or the increase of hematoma density (p = 0.140). This study reveals that normal postmortem changes significantly affect the extent and imaging characteristics of subdural hematoma and may therefore affect the interpretation of these findings on PMCT. Radiologists and forensic pathologists who use PMCT must be aware of these phenomena in order to correctly interpret PMCT findings in cases of subdural hemorrhages.

    Minor head trauma accounts for a significant proportion of pediatric emergency department (ED) visits. In children younger than 24 months, scalp hematomas are thought to be associated with the presence of intracranial injury (ICI). We investigated which scalp hematoma characteristics were associated with increased odds of ICI in children less than 17 years who presented to the ED following minor head injury and whether an underlying linear skull fracture may explain this relationship. This was a secondary analysis of 3,866 patients enrolled in the Canadian Assessment of Tomography of Childhood Head Injury (CATCH) study. Information about scalp hematoma presence (yes/no), location (frontal, temporal/parietal, occipital), and size (small and localized, large and boggy) was collected by emergency physicians using a structured data collection form. ICI was defined as the presence of an acute brain lesion on computed tomography. Logistic regression analyses were adjusted for age, sex, dangerous injury mechanism, irritability on examination, suspected open or depressed skull fracture, and clinical signs of basal skull fracture. ICI was present in 159 (4.1%) patients. The presence of a scalp hematoma (n = 1,189) in any location was associated with significantly greater odds of ICI (odds ratio [OR] = 4.4, 95% confidence interval [CI] = 3.06 to 6.02), particularly for those located in temporal/parietal (OR = 6.0, 95% CI = 3.9 to 9.3) and occipital regions (OR = 5.6, 95% CI = 3.5 to 8.9). Both small and localized and large and boggy hematomas were significantly associated with ICI, although larger hematomas conferred larger odds (OR = 9.9, 95% CI = 6.3 to 15.5). Although the presence of a scalp hematoma was associated with greater odds of ICI in all age groups, odds were greatest in children aged 0 to 6 months (OR = 13.5, 95% CI = 1.5 to 119.3). Linear skull fractures were present in 156 (4.0%) patients. Of the 111 patients with scalp hematoma and ICI, 57 (51%) patients had

    Abstract Background: The high recurrent rate of chronic subdural hematoma (CSDH) has consistently confused the neurosurgeons, and the role of atorvastatin in the management of CSDH has remained unclear over past decade, and atorvastatin seems to be a safe and cost-effective treatment to CSDH. Therefore, it is necessary to conduct a systematic review to discuss the effect of atorvastatin in CSDH. Method: We searched the PubMed, EMBASE, Cochrane Library, and the China Biology Medicine disc, up to March 2017, for published studies on the effects of atorvastatin in the management of CSDH, and reviewers performed a brief qualitative descriptive analysis of atorvastatin's efficacy in the management of CSDH. Results: Three eligible studies were included in this systematic review. Results indicated that atorvastatin accelerated hematoma absorption, decreased recurrence risk, and surgical requirement. Conclusion: Limited evidence suggests that oral atorvastatin may be beneficial in the management of CSDH. Further high-quality studies focused on dosage, duration, hematoma size are needed to further elucidate the role of atorvastatin in the management of CSDH. PMID:28658127

    Background and purpose Although unclear-onset ischemic stroke, including wake-up ischemic stroke, is drawing attention as a potential target for reperfusion therapy, acute unclear-onset intracerebral hemorrhage has been understudied. Clinical characteristics, hematoma features, and outcomes of patients who developed intracerebral hemorrhage during sleep or those with intracerebral hemorrhage who were unconscious when witnessed were determined. Methods Consecutive intracerebral hemorrhage patients admitted within 24 hours after onset or last-known normal time were classified into clear-onset intracerebral hemorrhage and unclear-onset intracerebral hemorrhage groups. Outcomes included initial hematoma volume, initial National Institutes of Health Stroke Scale score, hematoma growth on 24-hour follow-up computed tomography, and vital and functional prognoses at 30 days. Results Of 377 studied patients (122 women, 69 ± 11 years old), 147 (39.0%) had unclear-onset intracerebral hemorrhage. Patients with unclear-onset intracerebral hemorrhage had larger hematoma volumes (p = 0.044) and higher National Institutes of Health Stroke Scale scores (p < 0.001) than those with clear-onset intracerebral hemorrhage after multivariable adjustment for risk factors and comorbidities. Hematoma growth was similarly common between the two groups (p = 0.176). There were fewer patients with modified Rankin Scale (mRS) scores of 0-2 (p = 0.033) and more patients with mRS scores of 5-6 (p = 0.009) and with fatal outcomes (p = 0.049) in unclear-onset intracerebral hemorrhage group compared with clear-onset intracerebral hemorrhage as crude values, but not after adjustment. Conclusions Patients with unclear-onset intracerebral hemorrhage presented with larger hematomas and higher National Institutes of Health Stroke Scale scores at emergent visits than those with clear-onset intracerebral hemorrhage, independent of underlying characteristics.

    Rectus sheath hematoma is a clinical entity characterized by the presence of blood within rectus abdominis muscle sheath. The aim of this study was to analyze clinical characteristics, diagnostic approach, treatment strategy, and outcomes of patients with rectus sheath hematoma. Patients diagnosed and treated for spontaneous rectus sheath hematoma between March 2010 and March 2014 were included in the study. A total of 10 patients were diagnosed as spontaneous rectus sheath hematoma. The mean age was 66.5 ± 16.9 years, and the mean hospital stay was 4.4 ± 1.8 days. There was no mortality. Six patients were using anticoagulant or antiplatelet agents. Eight patients recovered after conservative treatment. Two patients underwent surgery. Spontaneous rectus sheath hematoma is associated with anticoagulant therapy. Cases with abdominal pain and a non-pulsatile abdominal mass particularly in elderly women should be kept in mind. Treatment is mostly based on supportive care to preserve hemodynamic stability.

    Little is known about the etiology or pathogenesis of angiosarcoma (AS). We describe a series of 5 cases of AS arising in chronic expanding hematomas. Inclusion criteria were the presence of a hematoma of at least 1-year duration and a thick fibrous wall surrounding the hematoma. Patients were 4 men and 1 woman; ages ranged from 43 to 71 years. Locations were the thigh (3), chest wall (1), and pelvic soft tissue involving the ischial bone (1). Hematoma duration ranged from 2 to 25 years. All cases had large cystic hematomas >10 cm; 2 had prior radiation. Thick fibrous walls surrounded the hematomas, with foci of hemosiderin and foamy histiocytes. Wall thickness ranged from 0.2 to 1.0 cm and varied within lesions. All AS were epithelioid, and in 3 cases the tumor invaded through the cyst wall. Immunoreactive nuclear c-myc was noted in 3/3 cases available for testing. Follow-up disclosed 4 patients developed metastatic disease, 3 of whom died of disease, 4, 8, and 15 months after diagnosis; the fourth patient is alive without disease after chemotherapy at 59 months. One patient without metastases is alive without disease 18 months after diagnosis; this tumor was confined to the cyst without penetration through the wall. We identified 4 similar cases in the literature, 3 as individual case reports (all epithelioid AS), and 1 as part of a series of AS. To our knowledge, this is the first series of AS arising in chronic expanding hematomas. Recognition of this unusual complication should alert clinicians to provide periodic clinical follow-up to these patients and to biopsy any case with sudden or uncontrolled enlargement. We recommend that excised chronic hematomas be well sampled histologically to search for AS and, if identified, to determine its extent and invasiveness.

    We report a case of subcorneal hematomas caused by excessive video game play in a 19-year-old man. The hematomas occurred in a setting of thrombocytopenia secondary to induction chemotherapy for acute myeloid leukemia. It was concluded that thrombocytopenia subsequent to prior friction from heavy use of a video game controller allowed for traumatic subcorneal hemorrhage of the hands. Using our case as a springboard, we summarize other reports with video game associated pathologies in the medical literature. Overall, cognizance of the popularity of video games and related pathologies can be an asset for dermatologists who evaluate pediatric patients.

    A 32-year-old man developed an extremely rare subdural hematoma after syringosubarachnoid shunting for syringomyelia. He presented with a 4-year history of neck pain and spastic paraparesis resulting from T-7 and T-8 vertebral body fracture suffered in a traffic accident at age 22 years. Magnetic resonance imaging revealed syringomyelia between the craniocervical junction and the T-10 level. The symptoms were slowly progressive, and a syringosubarachnoid shunting was performed. His spasticity improved after surgery, but he developed orthostatic headache 7 days after surgery. Magnetic resonance imaging of the brain demonstrated a thin subdural hematoma over the right cerebral convexity. The subdural hematoma resolved spontaneously within a week with conservative treatment. Vigorous cerebrospinal fluid outflow observed during surgery presumably lowered the pressure in the syrinx cavity, leading to significant but transient intracranial hypotension and consequently the formation of subdural hematoma.

    Postoperative hematomas are one of the most frequent complications following aesthetic surgery. Identifying risk factors for hematoma has been limited by underpowered studies from single institution experiences. To examine the incidence and identify independent risk factors for postoperative hematomas following cosmetic surgery utilizing a prospective, multicenter database. A prospectively enrolled cohort of patients who underwent aesthetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of major hematomas requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis was used to identify potential risk factors for hematomas including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, procedure by body region, and combined procedures. Of 129,007 patients, 1180 (0.91%) had a major hematoma. Mean age (42.0 ± 13.0 years vs 40.9 ± 13.9 years, P < 0.01) and BMI (24.5 ± 5.0 kg/m2 vs 24.3 ± 4.6 kg/m2, P < 0.01) were higher in patients with hematomas. Males suffered more hematomas than females (1.4% vs 0.9%, P < 0.01). Hematoma rates were higher in patients undergoing combined procedures compared to single procedures (1.1% vs 0.8%, P < 0.01), and breast procedures compared to body/extremity or face procedures (1.0% vs 0.8% vs 0.7%, P < 0.01). On multivariate analysis, independent predictors of hematoma included age (Relative Risk [RR] 1.01), male gender (RR 1.98), the procedure being performed in a hospital setting rather than an office-based setting (RR 1.68), combined procedures (RR 1.35), and breast procedures rather than the body/extremity and face procedures (RR 1.81). Major hematoma is the most common complication following aesthetic surgery. Male patients and those undergoing breast or combined procedures have a significantly higher risk of developing hematomas. 2. © 2017 The American Society

    Acute airway obstruction (AAO) after anterior cervical fusion (ACF) can be caused by postoperative retropharyngeal hematoma, which requires urgent recognition and treatment. However, the causes, evaluation, and appropriate treatment of this complication are not clearly defined. The purpose of this retrospective review of a prospective database was to investigate etiologic factors related to the development of AAO due to postoperative hematoma after ACF and formulate appropriate prevention and treatment guidelines. Cervical spinal cases treated at our academic institutions from 1998 to 2013 were evaluated. Demographic data, including factors related to hemorrhagic tendency, and operative data were analyzed. Patients who developed a hematoma were compared with those who did not to identify risk factors. Cases complicated by hematoma were reviewed, and times until development of hematoma and surgical evacuation were determined. Degrees of airway compromise and patient behavior were classified and evaluated. Treatment was selected according to the patient's status. Among 785 ACF procedures performed, there were nine cases (1.15%) of AAO. None of these nine patients had preoperative risk factors. In six patients (67%), the hematoma occurred within 24 h, whereas three patients (33%) presented with hematoma at a median of 72 h postoperatively. Four of the nine patients with AAO underwent evacuation of the hematoma. Two patients with inspiratory stridor, anterior neck swelling, and facial edema progressed to respiratory distress and their hematomas were removed by surgery, during which, sustained superficial venous bleeding was confirmed. Intubation was attempted several times in one patient with cyanosis, but is unsuccessful; cricothyroidotomy was performed in this patient and pumping in the small muscular arterial branches was confirmed in the operating room. All of the patients recovered without any complications. With rapid recognition and appropriate treatment

    The exact predictive factors for postoperative recurrence of chronic subdural hematoma (CSDH) are still unknown. Based on the preoperative magnetic resonance imaging (MRI), low recurrence rate of T1-hyperintensity hematoma was previously reported. We investigated the other types of radiological findings which are related to the recurrence rate of CSDH in large number of patients analyzed by multivariate logistic regression model. Preoperative MRI and postoperative computed tomography (CT) were performed and the influence of the preoperative use of antiplatelet or anticoagulant drugs was also studied. The overall recurrence rate was 9.3% (47 of 505 hematomas). The MRI T1-iso/hypointensity group showed a significantly higher recurrence rate (18.2%, 29 of 159) compared to the other groups (5.2%, 18 of 346; p < 0.001). Multivariate logistic regression analysis showed T1 classification was the solo significant prognostic predictor among various factors such as bilateral hematoma, antiplatelet or anticoagulant drug usage, residual hematoma on postoperative CT, and MRI classification (p < 0.001): adjusted odds ratio for the recurrence in T1-iso/hypointensity group relative to the T1-hyperintensity group was 5.58 [95% confidence interval (CI), 2.09–14.86] (p = 0.001). Postoperative residual hematoma and antiplatelet or anticoagulant drug usage did not increase the recurrence risk. The preoperative MRI findings, especially T1WI findings, have predictive value for postoperative recurrence of CSDH and the T1-iso/hypointensity group can be assumed to be a high recurrence risk group.

    It is difficult to evaluate the significant findings of epidural hematoma in magnetic resonance images (MRIs) obtained immediately after thoracic posterior screw fixation (PSF). Prospectively, immediate postoperative MRI was performed in 10 patients who underwent thoracic PSF from April to December 2013. Additionally, we retrospectively analyzed the MRIs from 3 patients before hematoma evacuation out of 260 patients who underwent thoracic PSF from January 2000 to March 2013. The MRI findings of 9 out of the 10 patients, consecutively collected after thoracic PSF, showed neurologic recovery with a well-preserved cerebrospinal fluid (CSF) space and no prominent hemorrhage. Even though there were metal artifacts at the level of the pedicle screws, the preserved CSF space was observed. In contrast, the MRI of 1 patient with poor neurologic outcome demonstrated a typical hematoma and slight spinal cord compression and reduced CSF space. In the retrospective analysis of the 3 patients who showed definite motor weakness in the lower extremities after their first thoracic fusion surgery and underwent hematoma evacuation, the magnetic resonance images before hematoma evacuation also revealed hematoma compressing the spinal cord and diminished CSF space. This study shows that epidural hematomas can be detected on MRI performed immediately after thoracic fixation surgery, despite metal artifacts and findings such as hematoma causing spinal cord compression. Loss of CSF space should be considered to be associated with neurologic deficit. Copyright © 2017 Elsevier Inc. All rights reserved.

    Chronic subdural hematoma is a commonly encountered disease in neurosurgic practice, whereas its increasing prevalence is compatible with the ageing population. Recommendations concerning postoperative thrombosis prophylaxis after burr-hole drainage of chronic subdural hematoma are lacking. The aim of this study was to analyze the correlation between recurrence of chronic subdural hematoma and postoperative application of thrombosis prophylaxis. Retrospective, consecutive sample of patients undergoing burr-hole drainage for chronic subdural hematoma over 3 years. Single, academic medical center. All patients undergoing surgical evacuation of a chronic subdural hematoma with burr-hole drainage. Exclusion: patients under the age of 18 years, who presented with an acute subdural hematoma and those who underwent a craniotomy. We compared patients receiving thrombosis prophylaxis treatment after burr-hole drainage of chronic subdural hematoma with those who were not treated. Primary outcome measure was reoperation of chronic subdural hematoma due to recurrence. Secondary outcome measures were thromboembolic and cardiovascular events, hematologic findings, morbidity, and mortality. In addition, a subanalysis comparing recurrence rate dependent on the application time of thrombosis prophylaxis (< 48 vs > 48 hr) was undertaken. Overall recurrence rate of chronic subdural hematoma was 12.7%. Out of the 234 analyzed patients, 135 (57.3%) received postoperative thrombosis prophylaxis (low-molecular-weight heparin) applied subcutaneously. Recurrence of chronic subdural hematoma occurred in the thrombosis prophylaxis group and control group in 12 patients (8.9%) and 17 patients (17.2%), respectively, showing no significant difference (odds ratio, 0.47 [95% CI, 0.21 - 1.04]). A subanalysis comparing recurrence rate of chronic subdural hematoma dependent on the application time of thrombosis prophylaxis (< 48 vs > 48 hr) showed no significant difference either (odds ratio, 2

    Lingual hematoma is a severe situation, which is rare and endangers the airway. It can develop due to trauma, vascular abnormalities, and coagulopathy. Due to its sudden development, it can be clinically confused with angioedema. In patients who applied to the doctor with complaints of a swollen tongue, lingual hematoma can be confused with angioedema, in particular, at the beginning if the symptoms occurred after drug use. It should especially be considered that dystonia in the jaw can present as drug-induced hyperkinetic movement disorder. Early recognition of this rare clinical condition and taking precautions for providing airway patency are essential. In this case report, we will discuss mimicking angioedema and caused by a bite due to dystonia and separation of the tongue from the base of the mouth developing concurrently with lingual hematoma.

    Six autopsy cases of subcortical hematoma caused by CAA were examined to elucidate the primary site of hemorrhage. Immunohistochemistry for amyloid beta-protein (A beta) revealed extensive CAA in the intrasulcal meningeal vessels rather than in the cerebral cortical vessels. All of the examined cases had multiple hematomas in the subarachnoid space, mainly in the cerebral sulci, as well as intracerebral hematomas. Each intracerebral hematoma was connected to the subarachnoid hematomas at the depth of cerebral sulci or through the lateral side of the cortex. There was no debris of the cerebral cortical tissue in the subarachnoid hematomas. In case 2, another solitary subarachnoid hematoma, which was not connected to any intracerebral hematoma, was seen. In all of these subarachnoid hematomas, many ruptured A beta-immunopositive arteries were observed. These ruptured arteries did not accompany any debris of the brain tissue, some of them were large in diameter (250-300 microm), and several of them were far from the cerebral cortex. Therefore, it was considered that they were not cortical arteries but meningeal arteries. Within the cerebral cortex, there were only a few ruptured arteries associated with small hemorrhages. There were no ruptured vessels within the intracerebral hematomas. There was a strong suggestion that all of the subarachnoid hematomas, including the solitary one in case 2, originated from the rupture of the meningeal arteries. The present study indicates that in some cases of subcortical hematoma caused by CAA, the primary hemorrhage occurs in the subarachnoid space, in particular the cerebral sulci, because of rupture of multiple meningeal arteries. Infarction occurs subsequently in the cortex around the hematoma, the hematoma penetrates into the brain parenchyma, and finally, a subcortical hematoma is formed.

    Congenital abnormalities of the aortic arch include interrupted aortic arch (IAA), coarctation of the aorta (CoA), and double aortic arch (DAA). Aortic arch repair is difficult and postoperative complications are common. However, postoperative tracheobronchial stenosis with respiratory insufficiency is an uncommon complication and is usually caused by increased aortic anastomotic tension. We report here a case of tracheal compression by a mediastinal hematoma following IAA surgery. The patient underwent a repeat operation to remove the hematoma and was successfully weaned off the ventilator.In cases of tracheobronchial stenosis after aortic arch surgery, airway compression by increased aortic anastomotic tension is usually the first diagnosis considered by clinicians. Other causes, such as mediastinal hematomas, are often ignored. However, the severity of symptoms with mediastinal hematomas makes this an important entity.

    IMPORTANCE Hematoma expansion is a potentially modifiable predictor of poor outcome following an acute intracerebral hemorrhage (ICH). The ability to identify patients with ICH who are likeliest to experience hematoma expansion and therefore likeliest to benefit from expansion-targeted treatments remains an unmet need. Hypodensities within an ICH detected by noncontrast computed tomography (NCCT) have been suggested as a predictor of hematoma expansion. OBJECTIVE To determine whether hypodense regions, irrespective of their specific patterns, are associated with hematoma expansion in patients with ICH. DESIGN, SETTING, AND PARTICIPANTS We analyzed a large cohort of 784 patients with ICH (the development cohort; 55.6% female), examined NCCT findings for any hypodensity, and replicated our findings on a different cohort of patients (the replication cohort; 52.7% female). Baseline and follow-up NCCT data from consecutive patients with ICH presenting to a tertiary care hospital between 1994 and 2015 were retrospectively analyzed. Data analyses were performed between December 2015 and January 2016. MAIN OUTCOMES AND MEASURES Hypodensities were analyzed by 2 independent blinded raters. The association between hypodensities and hematoma expansion (>6 cm3 or 33% of baseline volume) was determined by multivariable logistic regression after controlling for other variables associated with hematoma expansion in univariate analyses with P ≤ .10. RESULTS A total of 1029 patients were included in the analysis. In the development and replication cohorts, 222 of 784 patients (28.3%) and 99 of 245 patients (40.4%; 321 of 1029 patients [31.2%]), respectively, had NCCT scans that demonstrated hypodensities at baseline (κ = 0.87 for interrater reliability). In univariate analyses, hypodensities were associated with hematoma expansion (86 of 163 patients with hematoma expansion had hypodensities [52.8%], whereas 136 of 621 patients without hematoma expansion had hypodensities [21

    Rectus sheath hematoma is a rare clinical diagnosis, particularly in pregnancy. Due to unspecific symptoms, misdiagnosis is likely and could potentially endanger a patient as well as her fetus. A 26-year-old white woman presented with mild right-sided abdominal pain, which increased during palpation and movement, at 26 + 3 weeks' gestational age. Ultrasound imaging initially showed a round and well-demarcated structure, which appeared to be in contact with her uterine wall, leading to a suspected diagnosis of an infarcted leiomyoma. However, she reported increasing levels of pain and laboratory tests showed a significant drop in her initially normal hemoglobin level. A magnetic resonance imaging scan finally revealed a large type III rectus sheath hematoma on the right side. Because of progressive blood loss into her rectus sheath under conservative therapy, with a significant further decrease in her hemoglobin levels, surgical treatment via right-sided paramedian laparotomy was initiated. During the operation the arterial bleed could be ligated. She eventually achieved complete convalescence and delivered a healthy newborn spontaneously after 40 weeks of gestation. This case report highlights the clinical and diagnostic features of rectus sheath hematoma and shows the anatomical aspects of the rectus sheath, simplifying early and correct diagnosis.

    Research regarding the potency and potential of the fracture hematoma has begun to receive increasing attention. However, currently there is a paucity of relevant literature on the capability and composition of the fracture hematoma. This review briefly summarizes the regenerative fracture healing process and the close interplay between the skeletal and immune systems. The role of immune cells in wound healing is also discussed to clarify their involvement in immunological processes during regeneration. We attempt to describe the current state of knowledge regarding the fracture hematoma as the initial stage of the regenerative process of fracture healing. The review discusses how a better understanding of immune reactions in the hematoma may have implications for bone tissue engineering strategies. We conclude the review by emphasizing how additional investigations of the initial phase of healing will allow us to better differentiate between deleterious and beneficial aspects of inflammation, thereby facilitating improved fracture treatment strategies.

    Intracerebral hemorrhage (ICH) is a particularly devastating form of stroke with high mortality and morbidity. Hematomas are the primary cause of neurologic deficits associated with ICH. The products of hematoma are recognized as neurotoxins and the main contributors to edema formation and tissue damage after ICH. Finding a means to efficiently promote absorption of hematoma is a novel clinical challenge for ICH. Peroxisome proliferator-activated receptor gamma (PPARγ) and nuclear factor erythroid 2-related factor 2 (Nrf2), had been shown that, can take potential roles in the endogenous hematoma clearance. However, monascin, a novel natural Nrf2 activator with PPARγ agonist, has not been reported to play a role in ICH. This study was designed to evaluate the effect of monascin on neurological deficits, hematoma clearance and edema extinction in a model of ICH in rats. 164 adult male Sprague-Dawley (SD) rats were randomly divided into sham; vehicle; monascin groups with low dosages (1mg/kg/day), middle dosages (5mg/kg/day) and high dosages (10mg/kg/day) respectively. Animals were euthanized at 1, 3 and 7days following neurological evaluation after surgery. We examined the effect of monascin on the brain water contents, blood brain barrier (BBB) permeability and hemoglobin levels, meanwhile reassessed the volume of hematoma and edema around the hematoma by Magnetic Resonance Imaging (MRI) in each group. The high dosage of monascin significantly improved neurological deficits, reduced the volume of hematoma in 1-7days after ICH, decreased BBB permeability and edema formation in 1-3days following ICH. Our study demonstrated that the high dosage of monascin played a neuroprotective role in ICH through reducing BBB permeability, edema and hematoma volume. Copyright © 2017 Elsevier Inc.

    Warfarin is a commonly used anticoagulant agent that can have life-threatening complications, such as severe bleeding, which then require cessation of the treatment. Due to the widespread use of this therapy in recent years, incidences of its hemorrhagic complications have also increased significantly. In hemodynamically stable patients, it is possible to adopt conservative treatment strategies, such as ultrasound (US) therapy as an alternative. US is a physical therapy modality widely used in musculoskeletal disorders, but there is little evidence about its effectiveness for hemorrhagic complications because of the limited number of studies on this subject at present. A 77-year-old male who had been under oral anticoagulant therapy for 6½ years presented at the clinic with complaints of severe pain and numbness in the anterolateral thigh. US evaluation revealed iliopsoas hematoma. US treatment, administered as a physical therapy modality, resulted in faster resorption of the hematoma than expected. The patient fully recovered from clinically observed pain, meralgia paresthetica, and reduced patellar reflex.

    Chronic subdural hematoma is common in elderly individuals and surgical procedures are simple. The recurrence rate of chronic subdural hematoma, however, varies from 9.2 to 26.5% after surgery. The authors studied factors of the recurrence using univariate and multivariate analyses in patients with chronic subdural hematoma We retrospectively reviewed 239 consecutive cases of chronic subdural hematoma who received burr-hole surgery with irrigation and closed-system drainage. We analyzed the relationships between recurrence of chronic subdural hematoma and factors such as sex, age, laterality, bleeding tendency, other complicated diseases, density on CT, volume of the hematoma, residual air in the hematoma cavity, use of artificial cerebrospinal fluid. Twenty-one patients (8.8%) experienced a recurrence of chronic subdural hematoma. Multiple logistic regression found that the recurrence rate was higher in patients with a large volume of the residual air, and was lower in patients using artificial cerebrospinal fluid. No statistical differences were found in bleeding tendency. Techniques to reduce the air in the hematoma cavity are important for good outcome in surgery of chronic subdural hematoma. Also, the use of artificial cerebrospinal fluid reduces recurrence of chronic subdural hematoma. The surgical procedures can be the same for patients with bleeding tendencies.

    Vocal fold hematoma is traditionally managed with a period of voice rest, in the order of weeks, to allow natural resolution. This study is designed to examine the efficacy and safety of a number of hemoglobin-avid (vascular) lasers when used in the setting of acute vocal fold hematoma. Venous blood drawn from 4 white rabbits was used to create an array of subepithelial hematomas in the buccal cavities of each animal. Laser energy from I of 3 different lasers (532-nm pulsed potassium titanyl phosphate [KTP], 532-nm diode KTP, and 940-nm diode laser) was applied to each of the test hematomas at varying energy levels. Hematoma sites were photographed at days 0, 1, 5, 7, 9, and 12. Two animals were sacrificed on day 7 and the remainder on day 12. Histological evaluation of collateral tissue damage and residual hematoma was performed on biopsy specimens. Macroscopic and microscopic ulceration at laser-treated sites was mostly resolved by day 7. Inflammatory cell infiltrate was present in laser-treated and hematoma-only sites. Laser-treated samples showed alterations in vascularity. Hemoglobin-avid lasers may be beneficial in accelerating subepithelial hematoma resolution with a favorable tissue damage profile.

    Clopidogrel combined with aspirin is routinely prescribed after coronary artery stenting, in patients with acute coronary syndromes, and recently to prevent stroke in patients with acute minor ischemic stroke and TIA. Subdural hematomas are an important complication of antithrombotic treatment, but the risk associated with clopidogrel plus aspirin has not been previously defined. To quantify the risk of subdural hematoma associated with dual antiplatelet therapy with clopidogrel plus aspirin. Randomized clinical trials comparing clopidogrel plus aspirin with aspirin alone were identified by searching the Cochrane Central Register of Controlled Trials from 1990 to 2014, and restricted to those with more than 7 days of treatment. Two reviewers independently extracted data about subdural hematomas. Of 24 randomized trials testing clopidogrel added to aspirin, results for subdural hematoma were available for 11 trials, of which eight did not identify any subdural hematomas. The three trials reporting subdural hematomas were double-blind and included patients with recent lacunar stroke, acute coronary syndromes or atrial fibrillation with a total of 23,136 patients (mean age 66 years) and reported 39 subdural hematomas during a mean follow-up 2.1 years per patient. Clopidogrel plus aspirin was associated with a significantly increased risk of subdural hematoma compared with aspirin alone (risk ratio 2.0, 95% CI 1.0, 3.8; P = 0.04; fixed effects model; I2 for heterogeneity of 0%, P = 0.51). The average absolute incidence of subdural hematoma averaged 1.1 (95% CI 0.7,1.6) per 1000 patient - years among those assigned clopidogrel plus aspirin in 11 randomized trials. The absolute rate of subdural hematoma during dual antiplatelet therapy is low, averaging 1.1 per 1000 patient-years. Chronic treatment with clopidogrel plus aspirin significantly increases the risk of subdural hematoma compared with aspirin alone. © 2014 World Stroke Organization.

  20. Auricular hematoma and cauliflower deformation of the ear: from art to medicine.

    Auricular hematoma and cauliflower deformation of the ear are unique in several respects. Knowledge about it began, in antiquity, through artists, particularly Greek and Roman, and then Japanese in the 18th century with their representation of cauliflower deformation of the ear on sculptures and paintings of pugilists and wrestlers. It is only in the 19th century that physicians began to make substantive progress in understanding this abnormality. It was first thought to be associated with mental disease, but by the beginning of the 20th century, its etiology was recognized as being caused by trauma and was then named auricular hematoma. The second step in the understanding of this affliction was the observation that auricular hematoma progresses toward cauliflower deformation of the ear, which was named cauliflower ear. Recognition of this evolution led to the development of therapies. During the second half of the 20th century, different treatments were developed. They included various hematoma drainage techniques with special bandages to prevent hematoma recurrence and ensuing progression to cauliflower ear. In summary, cauliflower deformation of the ear is an old artistic affliction that has only recently received medical attention.

    Muscle hematomas are rare complications in dengue hemorrhagic fever (DHF). We report a case of 58-year-old-female admitted with dengue fever who developed spontaneous rectus sheath hematoma complicating DHF. She presented with progressive thrombocytopenia with platelet count reaching 13000/μL at its lowest point. There was evidence of plasma leakage and persistent cough during the course of illness. During the recovery phase, she reported severe abdominal pain and developed hematoma in the right rectus sheath, which was confirmed by abdominal computed-tomography scan and serial magnetic resonance imaging. This complication during convalescent period of DHF needs to be recognized so it can be managed appropriately.

    The diagnosis and management of acute subdural hematoma is important in neurosurgery practice. Rapid spontaneous resolution of acute subdural hematoma within a few hours is seen rarely on the CT scan. We present a case that enlarged the existent subdural hygroma showing rapid resolution of acute subdural hematoma with resolution in 9 hours after the trauma. Additionally, the follow-up CT scans in the 1st month showed the decrease of enlargement of subdural hygroma. The resolution of acute subdural hematoma and effect of acute subdural hematoma on subdural hygroma must be considered during management. The relation of acute subdural hematoma and subdural hygroma is important for the resolution and management of acute subdural hematoma.

    Traumatic spinal subarachnoid hematoma, associated or not with a concurrent subdural hematoma, has rarely been described. The evolution of such hematomas is heterogeneous. This study aims at defining the most accurate management, which is currently not standardized. A 20-year-old man, victim of a high-kinetic road accident 5 days before and with several nonneurologic nonsurgical vertebral fractures, experienced a sudden dorsolumbar pain radiating to his lower limbs. A rapidly progressive asymmetric paraparesis with loss of reflexes was noticed, associated with bilateral global hypoesthesia of the lower limbs and with acute urinary retention, whereas the anal tonicity was preserved (American Spinal Injury Association C). Magnetic resonance imaging scan revealed a conus medullaris compression at the level of the L1-L2 vertebrae by an intradural expansive mass. Immediate surgical decompression revealed a strictly subarachnoid hematoma. Venous bleeding was seen at the level of the conus medullaris and controlled. Pathologic examination of the clot excluded an underlying tumor or vascular abnormality. The complete coagulation profile was normal. Six weeks after surgery, the neurologic examination revealed only a slight tactile hypoesthesia of the left thigh. With only 4 reported cases, purely subarachnoid spinal hematomas remain widely rarer than epidural hematomas. The reported case possesses a certain number of peculiarities: young age, pure subarachnoid location, lumbar location, occurrence after a car accident, subacute onset, and excellent neurologic recovery. In our opinion, a symptomatic subarachnoid spinal hematoma should be surgically evacuated at the early phase so neurologic recovery can be expected. Copyright © 2018 Elsevier Inc.

    Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient's left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

    Postoperative cervical hematoma after major head and neck surgery is a feared complication. However, risk factors for developing this complication and attributable costs are not well-established. The Nationwide Inpatient Sample database was utilized compare patients with and without postoperative cervical hematoma. Logistic regression was used to analyze risk factors for hematoma formation and 30-day mortality. Total inpatient length of stay (LOS) and costs were fit to generalized linear models. Of 32 071 patients, 1098 (3.4%) experienced a postoperative cervical hematoma. Male sex (odds ratio [OR] 1.38; P < .0001), black race (OR 1.35; P = .010), 4 or more comorbidities (OR 1.66; P < .0001), or presence of a preoperative coagulopathy (OR 6.76; P < .0001) were associated. Postoperative cervical hematoma was associated with 540% increased odds of death (P < .0001). The LOS and total excess costs were 5.14 days (P < .0001) and $17 887.40 (P < .0001), respectively. Although uncommon, postoperative cervical hematoma is a life-threatening complication of head and neck surgery with significant implications for outcomes and resource utilization. © 2018 Wiley Periodicals, Inc.

    Minimally invasive endoscopic hematoma evacuation is a promising treatment option for intracerebral hemorrhage. However, the technique still needs improvement. We report our clinical experience of using this technique to evacuate deep-seated basal ganglia hematomas. The frontal approach was used in most patients. The preoperative and postoperative hematoma volumes, Glasgow Coma Scale, hematoma evacuation rate, 30-day mortality, and long-term outcome defined by the modified Rankin Scale were analyzed retrospectively. The surgical duration per milliliter of clot (DPM) was calculated. The learning curve for this technique was determined based on the relation between the DPM and evacuation rate per the number of cases experienced. A total of 24 patients were enrolled. The evacuation rate was 87% ± 10%. The average Glasgow Coma Scale score recovered from 8 to 13 after surgery. Twenty-one patients had follow-up data. The follow-up time was 13 ± 6 months. The 30-day mortality after surgery was zero. Forty-eight percent of patients (10/21) achieved a favorable outcome. The DPM (P = 0.92) and evacuation rate (P = 0.64) did not change substantially with the number of cases experienced. Endoscopic port surgery for hematoma evacuation via the frontal approach is a safe surgical option for deep-seated basal ganglia hematomas. This technique is minimally invasive and may be helpful to provide better long-term outcomes for selected patients. For neurosurgeons, the learning curve for this technique is steep, which implies that the skills needed for our technique can be easily acquired. Copyright © 2017 Elsevier Inc. All rights reserved.

    2015-01-01

    5 dogs (a Newfoundland, Golden Retriever, Shiba Inu, Staffordshire Terrier, and Vizsla) were referred for evaluation and treatment of unilateral aural hematomas within a week after their formation. Aural hematomas involved the left (3) or right (2) ears. With patients under anesthesia, the aural hematomas were approached surgically from the convex, or lateral, pinnal surface. Two small incisions were used to position a vacuum drain into the incised hematoma cavity. The drain exited at the base of the pinna and adjacent cervical skin. The free end of the drain was attached to a vacuum reservoir for 18 to 21 days. Drains and skin sutures were removed at this time along with the protective Elizabethan collar. All hematomas resolved and surgical sites healed during the minimum 6-month follow-up period. Cosmetic results were considered excellent in 4 of 5 patients. Slight wrinkling of the pinna in 1 patient resulted from asymmetric enlargement of the cartilaginous walls of the hematoma, where vacuum application resulted in a slight folding of the redundant lateral cartilage wall. The described treatment was efficient, economical, and minimally invasive and required no bandaging or wound care. Placement of the drain tubing on the convex (lateral) aspect sheltered the system from displacement by patients with an Elizabethan collar in place. Overall cosmetic results were excellent; asymmetric enlargement of the cartilaginous walls of the hematoma with slight folding of the pinna was seen in 1 patient.

    Rectus sheath hematoma is an uncommon but potentially serious bleeding complication that can occur spontaneously or as a result of anticoagulation administration. Case number one: A 62 year old chronically ill Caucasian female develops a rectus sheath hematoma seven days after hospital discharge. The previous hospitalization included low molecular weight heparin administration for deep vein thrombosis prophylaxis. The patient ultimately chooses comfort care and expires due to sepsis and respiratory failure. Case number two: A 79 year old Caucasian male develops a rectus sheath hematoma during hospital admission where LMWH is used for deep vein thrombosis prophylaxis. He is managed conservatively; however, his hematocrit drops from 46 to 25.8%. Case number three: A 44 year old chronically ill Caucasian female is treated with therapeutic low molecular weight heparin for recent deep vein thrombosis during a hospital admission. She develops a large rectus sheath hematoma requiring embolization as well as blood transfusion. We believe this reflects an underreported significant cause of morbidity and mortality with low molecular weight heparin administration. We review the pathophysiology of rectus sheath hematoma as well as its presentation, diagnosis, and treatment. We identify at-risk populations and proposed contributing factors. We also discuss factors leading to underreporting as well as preventive strategies implemented at our institution.

    Patient: Male, 30 Final Diagnosis: Acute epidural hematoma Symptoms: — Medication: — Clinical Procedure: Observation Specialty: Neurosurgery Objective: Unusual clinical course Background: Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited underlying primary brain damage from the traumatic event. The decision to perform a surgery in a patient with a traumatic extraaxial hematoma is dependent on several factors (neurological status, size of hematoma, age of patients, CT findings) but also may depend on the judgement of the treating neurosurgeon. Case Report: A 30-year old man arrived at our Emergency Department after a traumatic brain injury. General examination revealed severe headache, no motor or sensory disturbances, and no clinical signs of intracranial hypertension. A CT scan documented a significant left fronto-parietal epidural hematoma, which was considered suitable for surgical evacuation. The patient refused surgery. Following CT scan revealed a minimal increase in the size of the hematoma and of midline shift. The neurologic examination maintained stable and the patient continued to refuse the surgical treatment. Next follow up CT scans demonstrated a progressive resorption of hematoma. Conclusions: We report an unusual case of a remarkable epidural hematoma managed conservatively with a favorable clinical outcome. This case report is intended to rather add to the growing knowledge regarding the best management for this serious and acute pathology. PMID:26567227

    In the young population, spontaneous rupture of Achilles tendon is very rare. The big hematoma is also rare finding of the Achilles tendon partial rupture. It is usually seen with complete rupture. We presented imaging findings of 4 years follow up of the spontaneous partial rupture of Achilles tendon presenting with giant expanding hematoma and mimicking complete rupture radiologically. We discussed the alterations of tendon signal intensity and result of conservative therapy after partial rupture with big hematoma in the long term. A 29 year-old man, applied with pain and swelling in the retrocalcaneal region of left ankle. He did not have chronic metabolic disease. He was not active in physical activities. X-ray radiograms were normal. At magnetic resonance images (MRI), there was an intratendinous big hematoma, subcutanous fat planes were edematous around tendon. The diagnosis was partial rupture and giant hematoma. Hematoma was drained. The conservative treatment was applied and his complaints disappeared. After treatment, approximately 4 years later, control MRI showed thickened and hypointense tendon in all images. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    To compare post-biopsy hematoma rates between ultrasound guided-fine needle aspiration and ultrasound guided-core needle biopsy, and to investigate risk factors for post-biopsy hematoma. A total of 5304 thyroid nodules which underwent ultrasound guided biopsy were included in this retrospective study. We compared clinical and US features between patients with and without post-biopsy hematoma. Associations between these features and post-biopsy hematoma were analyzed. Post-biopsy hematoma rate was 0.8% (43/5121) for ultrasound guided-fine needle aspiration and 4.9% (9/183) for ultrasound guided-core needle biopsy (P < 0.001). For ultrasound guided-fine needle aspiration, gender, age, size, presence of vascularity, and suspicious US features were not associated with post-biopsy hematoma according to experience level. Post-biopsy hematoma occurred significantly more with ultrasound guided-core needle biopsy (9/179, 5.0%) than with ultrasound guided-fine needle aspiration (9/1138, 0.8%) (P < 0.001) in experienced performers and ultrasound guided-core needle biopsy was the only significant risk factor for post-biopsy hematoma (adjusted Odds Ratio, 6.458, P < 0.001). Post-biopsy hematoma occurred significantly more in ultrasound guided-core needle biopsy than in ultrasound guided-fine needle aspiration and ultrasound guided-core needle biopsy was the only independent factor of post-biopsy hematoma in thyroid nodules.

    This study investigates the potential clinical utility in the emergency department (ED) of an index of brain electrical activity to identify intracranial hematomas. The relationship between this index and depth, size, and type of hematoma was explored. Ten minutes of brain electrical activity was recorded from a limited montage in 38 adult patients with traumatic hematomas (CT scan positive) and 38 mild head injured controls (CT scan negative) in the ED. The volume of blood and distance from recording electrodes were measured by blinded independent experts. Brain electrical activity data were submitted to a classification algorithm independently developed traumatic brain injury (TBI) index to identify the probability of a CT+traumatic event. There was no significant relationship between the TBI-Index and type of hematoma, or distance of the bleed from recording sites. A significant correlation was found between TBI-Index and blood volume. The sensitivity to hematomas was 100%, positive predictive value was 74.5%, and positive likelihood ratio was 2.92. The TBI-Index, derived from brain electrical activity, demonstrates high accuracy for identification of traumatic hematomas. Further, this was not influenced by distance of the bleed from the recording electrodes, blood volume, or type of hematoma. Distance and volume limitations noted with other methods, (such as that based on near-infrared spectroscopy) were not found, thus suggesting the TBI-Index to be a potentially important adjunct to acute assessment of head injury. Because of the life-threatening risk of undetected hematomas (false negatives), specificity was permitted to be lower, 66%, in exchange for extremely high sensitivity.

We report the case of an 83 y.o. woman with right facio-brachio-crural hemiparesis, left deviation of the head and aphasia who developed, after thrombolytic therapy, a spontaneous sternocleidomastoid muscle hematoma that regressed few days later. To our knowledge, this is the first case reported in the literature of asymptomatic and spontaneous skeletal muscle hematoma following thrombolysis for the treatment of acute ischemic stroke. The occurrence of lateral cervical tuberculosis lymphadenitis ipsilateral to sternocleidomastoid muscle hematoma may suggest a causal relationship between local chronic inflammation of active mycobacterial infection and thrombolysis-related extravasation. This case should suggest caution in thrombolytic treatment in patients with chronic immune dysregulation and vascular inflammation such as extra-pulmonary tuberculosis. Copyright © 2014 Elsevier B.V.

    Background Postoperative spinal epidural hematoma (POSEH) is different from spontaneous or post-spinal procedure hematoma because of the application of suction drains. However, it appeared that suction drains were not effective for prevention of POSEH in previous studies. The purpose of this study was to test our hypothesis that POSEH can be caused by hypercoagulability. Methods This was an experimental study. One hundred fifty milliliters of blood was donated from each of the 12 consecutive patients who underwent spine surgery and infused into 3 saline bags of 50 mL each. One of the 3 bags in each set contained 5,000 units of thrombin. All of them were connected to 120 ± 30 mmHg vacuum suctions: drainage was started 8 minutes after connection to the vacuum system for 12 normal blood bags (BV8) and 12 thrombin-containing blood bags (TBV8) and 15 minutes after connection for the remaining 12 normal blood bags (BV15). The amount of initial and remaining hematoma at 20 minutes, 120 minutes, and 24 hours after vacuum application were measured by their weight (g). The primary endpoint was the difference between BV8 and TBV8. The secondary end point was the difference between BV8 and BV15. Results The remaining hematoma in TBV8 was significantly greater than that in BV8 at all measurement points: 46.3 ± 12.4 vs. 17.0 ± 1.3 (p = 0.000) at 20 minutes; 33.0 ± 8.2 vs. 16.3 ± 1.2 (p = 0.000) at 120 minutes; and 26.1 ± 4.0 vs. 15.8 ± 1.6 (p = 0.000) at 24 hours after vacuum application. The remaining hematoma of BV15 was significantly greater than that of BV8 at all measurement points: 30.0 ± 12.0 vs. 17.0 ± 1.3 (p = 0.002) at 20 minutes; 24.2 ± 7.6 vs. 16.3 ± 1.2 at 120 minutes (p = 0.002); and 22.2 ± 6.6 vs. 15.8 ± 1.6 (p = 0.004) at 24 hours after vacuum application. Conclusions With a suction drain in place, the amount of remaining hematoma could be affected by coagulability. Thrombin-containing local hemostatics and the length of time elapsed before the

    The evolution of intracerebral hematoma and perihematoma edema in the ultra-early period on computed tomographic (CT) scans in patients with intracerebral hemorrhage (ICH) is not well understood. We aimed to investigate hematoma and perihematoma changes in "neutral brain" models of ICH. One human and five goat cadaveric heads were used as "neutral brains" to provide physical properties of brain without any biological activity or new bleeding. ICH was induced by slow injection of 4 ml of fresh human blood into the right basal ganglia of the goat brains. Similarly, 20 ml of fresh blood was injected deep into the white matter of the human cadaver head in each hemisphere. Serial CT scans of the heads were obtained immediately after hematoma induction and then 1, 3, and 5 hours afterward. Analyze software (AnalyzeDirect, Overland Park, KS, USA) was used to measure hematoma and perihematoma hypodensity volumes in the baseline and follow-up CT scans. The initial hematoma volumes of 11.6 ml and 10.5 ml in the right and left hemispheres of the cadaver brains gradually decreased to 6.6 ml and 5.4 ml at 5 hours, showing 43% and 48% retraction of hematoma, respectively. The volume of the perihematoma hypodensity in the right and left hemisphere increased from 2.6 ml and 2.2 ml in the 1-hour follow-up CT scans to 4.9 ml and 4.4 ml in the 5-hour CT scan, respectively. Hematoma retraction was also observed in all five goat brains ICH models with the mean ICH volume decreasing from 1.49 ml at baseline scan to 1.01 ml at the 5-hour follow-up CT scan (29.6% hematoma retraction). Perihematoma hypodensity was visualized in 70% of ICH in goat brains, with an increasing mean hypodensity volume of 0.4 ml in the baseline CT scan to 0.8 ml in the 5-hour follow-up CT scan. Our study demonstrated that substantial hematoma retraction and perihematoma hypodensity occurs in ICH in the absence of any new bleeding or biological activity of surrounding brain. Such observations suggest that active

    To identify factors determining the clinical characteristics and prognosis of acute subdural hematoma (ASDH) arising from boxing injuries by comparing with ASDH due to any nonboxing cause. Two groups were selected for this study: 10 patients with ASDH because of boxing injuries and 26 patients with nonboxer ASDH. All of the patients underwent neurologic examination by neurosurgeons. Primary resuscitation and stabilization as well as operative therapy were performed to all patients according to the European Brain Injury Consortium Guidelines. Two groups were compared in terms of age, the Glasgow Coma Scale at admission, neurologic findings, craniogram and brain computed tomography scan findings, operative findings, and prognosis. As potential prognostic indicators for boxers, the time interval until surgery, the Glasgow Outcome Scale, hematoma thickness, midline shift, and the site of bleeding were analyzed. The characteristics of patients because of boxing injuries are that patients were younger, had lucid interval, and had no cerebral contusion or contralateral brain injury. There was no significant difference in initial Glasgow Coma Scale, hematoma thickness, midline shift, and their prognosis. The most peculiar clinical presentation of boxers' ASDH was that all bleedings were limited from "bridging veins" or "cortical veins." The prognosis of boxers was most closely correlated with the site of bleeding (r2 = 0.81; p = 0.0001) and the midline shift (r2 = 0.67; p = 0.007). Our study shows that ASDH because of boxing is characterized by bleeding from bridging or cortical veins, and that the site of bleeding is a significant determinant of their prognosis.

    The authors provide a structured review of reported cases of floor-of-mouth hematoma during or after dental implantation and frequent causes and management and present a related case. An online search of the medical literature was conducted from 1990 through 2016. The following search terms were used: floor of mouth hematoma, sublingual hematoma, dental implant hematoma, implant in mandible, and complication of dental implant. Abstracts were screened for relevance to the aims of the review. Relevant reports in the English language were included and referenced. The articles were reviewed for patient demographics, implant location, coagulopathy, pre- or postoperative imaging, airway management, treatment of the hematoma, and management of the offending implant. The literature search identified 25 reported cases. Hemorrhage was caused by perforation of the lingual cortex in 84% of cases (n = 21). Airway obstruction resulted in emergency intubation or tracheostomy in 68% of patients (n = 17). Most cases (n = 18; 72%) required surgical management in the hospital setting. Management of the offending implant was reported inconsistently. Of 17 reported cases, 5 implants had to be removed, 9 remained in situ, and in 3 cases implant placement was abandoned. Only 1 case involved preoperative 3-dimensional (3D) imaging before implant insertion. The authors report on an additional case with a serious floor-of-mouth hematoma that required immediate surgical evacuation and hemostasis. Serious complications, such as floor-of-mouth hematoma after dental implant insertion, can occur, which could be life-threatening. Preoperative 3D imaging helps to visualize the individual mandibular shape, which could decrease the incidence of serious complications. If injury to vessels of the floor of the mouth cannot be confidently excluded, then further assessment and treatment are recommended before the patient is discharged.

    Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery. The association of epidural hematomas in sickling hemoglobinopathies is reviewed. In all cases, we noticed one episode of sickle cell crisis just before the occurrence of spontaneous EDH. Perhaps this crisis puts an extra demand over the hematopoietic skull tissue disrupting inner and outer skull margins leading to spontaneous EDH and subgaleal hematoma. PMID:28413532

    Contemporary chronic total occlusion (CTO) percutaneous coronary interventional (PCI) techniques are increasingly dependent upon dissection and reentry techniques (DARTs) especially for long occluded lesions. DARTs can result in compressive hematomas during CTO interventions and traditional treatment with balloon angioplasty and/or coronary stenting are often suboptimal and may extend the hematoma distally. We describe the novel use of a cutting balloon to "express" these compressive hematomas and restore antegrade coronary blood flow. © 2017 Wiley Periodicals, Inc.

    Traumatic brain injury is a major cause of morbidity and mortality worldwide, often necessitating neurosurgical intervention to evacuate intracranial bleeding. Since the early 2000s, Cambodia has been undergoing a rapid increase in motorcycle transit and in road traffic accidents, but the prevalence of helmet usage remains low. Epidural hematomas are severe traumatic brain injuries that can necessitate neurosurgical intervention. This is a retrospective cohort study of patients with epidural hematoma secondary to motorcycle accidents who presented to a major national tertiary care center in Phnom Penh, Cambodia, between November 2013 and March 2016. All patients were diagnosed with computed tomography of the head. In this cohort, 21.6% of patients in motorcycle accidents presented with epidural hematoma and 89.1% of patients were men, 47.6% were intoxicated, and were 87.8% were not wearing helmets at the moment of impact. Not wearing a helmet was associated with a 6.90-fold increase in odds of presenting with a moderate-to-severe Glasgow coma scale score and a 3.76-fold increase in odds of requiring craniotomy or craniectomy for evacuation of hematoma. Male sex was also associated with increased odds of higher clinical severity at presentation and indication for craniotomy or craniectomy, and alcohol intoxication at the time of accident was not associated with either. Helmet usage is protective in reducing the severity of presentation and need for neurosurgical intervention for patients with epidural hematoma secondary to motorcycle accidents.

    Spinal acupuncture is a relatively safe and common analgesic treatment, but it may be complicated by serious adverse effects, such as direct spinal cord and nerve root injury, subdural empyema, and epidural abscesses. In this report we compare our case of an extremely uncommon spinal epidural hematoma, which appeared after treatment by acupuncture, with other similar documented cases. This is the case of a 64-year-old man who presented a left hemiparesis associated with paraesthesia. This appeared several hours after acupuncture treatment for left lumbosciatic pain. The cervicothoracic spine magnetic resonance imaging (MRI) scan showed a cervicothoracic spinal epidural hematoma from C2 to T12. The rapid improvement of the patient's neurologic symptoms justified the adoption of a conservative treatment strategy. This gave excellent long-term results. Although a post-acupuncture spinal epidural hematoma (paSEH) is very rare, there are only 6 documented cases, it is a possible complication from acupuncture on the back. The use of very thin needles can produce bleeding, probably venous, in the epidural space. In general, this evolves more slowly than other kinds of epidural hematomas. The symptoms are also less severe, warranting less frequent surgical intervention, and in general there is a good outcome. The possibility of hematoma makes acupuncture contraindicated in patients who have coagulation disorders. The onset of severe spinal pain after spinal or paraspinal acupuncture treatment should lead to the suspicion of a paSEH, and a spinal MRI should be carried out. Copyright © 2017 Elsevier Inc.

    We aimed to determine the association between scalp hematoma characteristics and traumatic brain injuries in young children with blunt head trauma who have no other symptoms or signs suggestive of traumatic brain injuries (defined as "isolated scalp hematomas"). This was a secondary analysis of children younger than 24 months with minor blunt head trauma from a prospective cohort study in 25 Pediatric Emergency Care Applied Research Network emergency departments. Treating clinicians completed a structured data form. For children with isolated scalp hematomas, we determined the prevalence of and association between scalp hematoma characteristics and (1) clinically important traumatic brain injury (death, neurosurgery for traumatic brain injury, intubation >24 hours for traumatic brain injury, or positive computed tomography (CT) scan in association with hospitalization ≥2 nights for traumatic brain injury); and (2) traumatic brain injury on CT. Of 10,659 patients younger than 24 months were enrolled, 2,998 of 10,463 (28.7%) with complete data had isolated scalp hematomas. Clinically important traumatic brain injuries occurred in 12 patients (0.4%; 95% confidence interval [CI] 0.2% to 0.7%); none underwent neurosurgery (95% CI 0% to 0.1%). Of 570 patients (19.0%) for whom CTs were obtained, 50 (8.8%; 95% CI 6.6% to 11.4%) had traumatic brain injuries on CT. Younger age, non-frontal scalp hematoma location, increased scalp hematoma size, and severe injury mechanism were independently associated with traumatic brain injury on CT. In patients younger than 24 months with isolated scalp hematomas, a minority received CTs. Despite the occasional presence of traumatic brain injuries on CT, the prevalence of clinically important traumatic brain injuries was very low, with no patient requiring neurosurgery. Clinicians should use patient age, scalp hematoma location and size, and injury mechanism to help determine which otherwise asymptomatic children should undergo

    To present, to our knowledge, the first case of a single bilateral extradural hematoma due to superior sagittal sinus detachment that was treated conservatively with an excellent outcome. Bilateral extradural hematomas are a rare condition, accounting for only 2%-5% of all extradural hematomas. They can be either 2 distinct hematomas on either side or 1 single bilateral hematoma mostly due to sagittal sinus injury, with the latter being the most rare owing to the firm attachment of the sinus to its subperiosteal loggia. These hematomas usually require immediate surgical evacuation, as patients present with decreased level of consciousness, and have good postoperative outcomes. We present a bilateral extradural hematoma due to superior sagittal sinus injury, which was treated conservatively. The patient had an excellent recovery, with no residual neurological deficits and a Glasgow outcome scale of 5 on discharge. Bilateral extradural hematomas due to superior sagittal sinus injury almost always require surgical intervention. We present a patient who was treated conservatively with an excellent outcome and we also perform a review of the current literature. Copyright © 2016 Elsevier Inc. All rights reserved.

    Extraparenchymal spinal cord hematoma has been described in veterinary medicine in association with neoplasia, intervertebral disk disease, and snake envenomation. There are rare reports of spontaneous extraparenchymal spinal cord hematoma formation with no known cause in human medicine. Multiple cases of spontaneous extraparenchymal spinal cord hematoma have not been described previously in veterinary medicine. To describe the signalment, clinical findings, magnetic resonance imaging (MRI) features, and surgical outcomes in histopathologically confirmed extraparenchymal spinal cord hematomas in dogs with no identified underlying etiology. Six dogs had MRI of the spinal cord, decompressive spinal surgery, and histopathologic confirmation of extraparenchymal spinal cord hematoma not associated with an underlying cause. Multi-institutional retrospective study. Six patients had spontaneous extraparenchymal spinal cord hematoma formation. MRI showed normal signal within the spinal cord parenchyma in all patients. All hematomas had T2-weighted hyperintensity and the majority (5/6) had no contrast enhancement. All dogs underwent surgical decompression and most patients (5/6) returned to normal or near normal neurologic function postoperatively. Follow-up of the patients (ranging between 921 and 1,446 days) showed no progression of neurologic clinical signs or any conditions associated with increased bleeding tendency. Before surgery and histopathology confirming extraparenchymal hematoma, the primary differential in most cases was neoplasia, based on the MRI findings. This retrospective study reminds clinicians of the importance of the combination of advanced imaging combined with histopathologic diagnosis. The prognosis for spontaneous spinal cord extraparenchymal hematoma with surgical decompression appears to be favorable in most cases.

    We prospectively investigated temporal and spatial evolution of intramural hematomas in patients with acute spontaneous internal carotid artery dissection using repeated magnetic resonance imaging over six-months. The aim of the present study was to assess dynamic changes of intramural hematoma in patients with acute spontaneous internal carotid artery dissection at multiple follow-up time-points with T1w, PD/T2w, and magnetic resonance angiography. We performed serial multiparametric magnetic resonance imaging in 10 patients with spontaneous internal carotid artery dissection on admission, at days 1, 3, 7-14 and at months 1·5, 3, and 6. We calculated the volume and extension of the hyperintense intramural hematoma using T1w and PD/T2w fat suppressed sequences and assessed the degree of stenosis due to the hematoma using magnetic resonance angiography. Mean interval from symptom onset to first magnetic resonance imaging was two-days (SD 2·7). Two patients presented with ischemic stroke, three with transient ischemic attacks, and five with pain and local symptoms only. Nine patients had a transient increase of the intramural hematoma volume, mainly up to day 10 after symptom onset. Fifty percent had a transient increase in the degree of the internal carotid artery stenosis on MRA, one resulting in a temporary occlusion. Lesions older than one-week were predominantly characterized by a shift from iso- to hyperintese signal on T2w images. At three-month follow-up, intramural hematoma was no longer detectable in 80% of patients and had completely resolved in all patients after six-months. Spatial and temporal dynamics of intramural hematomas after spontaneous internal carotid artery dissection showed an early volume increase with concomitant progression of the internal carotid artery stenosis in 5 of 10 patients. Although spontaneous internal carotid artery dissection overall carries a good prognosis with spontaneous hematoma resorption in all our patients, early

Seventy-six-year-old male and 75-year-old female patients with cataract and pseudoexfoliative glaucoma (XFG) uncontrolled with maximum medical therapy both underwent GATT combined with phacoemulsification. Shortly after the surgery, intracapsular hematoma behind the intraocular lens (IOL) were noted in both patients. Hematoma cleared in both of them via IOL extraction-anterior vitrectomy and YAG-laser capsulotomy, respectively. Hematoma cleared in both patients without any surgical complications. Vision loss due to unclearing intracapsular hematoma might be an early complication of combined GATT and phacoemulsification surgery.

    Early hematoma growth is not uncommon in patients with intracerebral hemorrhage and is an independent predictor of poor functional outcome. The purpose of our study was to report and validate the use of our newly identified computed tomographic (CT) blend sign in predicting early hematoma growth. Patients with intracerebral hemorrhage who underwent baseline CT scan within 6 hours after onset of symptoms were included. The follow-up CT scan was performed within 24 hours after the baseline CT scan. Significant hematoma growth was defined as an increase in hematoma volume of >33% or an absolute increase of hematoma volume of >12.5 mL. The blend sign on admission nonenhanced CT was defined as blending of hypoattenuating area and hyperattenuating region with a well-defined margin. Univariate and multivariable logistic regression analyses were performed to assess the relationship between the presence of the blend sign on nonenhanced admission CT and early hematoma growth. A total of 172 patients were included in our study. Blend sign was observed in 29 of 172 (16.9%) patients with intracerebral hemorrhage on baseline nonenhanced CT scan. Of the 61 patients with hematoma growth, 24 (39.3%) had blend sign on admission CT scan. Interobserver agreement for identifying blend sign was excellent between the 2 readers (κ=0.957). The multivariate logistic regression analysis demonstrated that the time to baseline CT scan, initial hematoma volume, and presence of blend sign on baseline CT scan to be independent predictors of early hematoma growth. The sensitivity, specificity, positive and negative predictive values of blend sign for predicting hematoma growth were 39.3%, 95.5%, 82.7%, and 74.1%, respectively. The CT blend sign could be easily identified on regular nonenhanced CT and is highly specific for predicting hematoma growth. © 2015 American Heart Association, Inc.

    Liao, Chun-Chih; Xiao, Furen; Wong, Jau-Min; Chiang, I.-Jen

    Computed tomography (CT) of the brain is preferred study on neurological emergencies. Physicians use CT to diagnose various types of intracranial hematomas, including epidural, subdural and intracerebral hematomas according to their locations and shapes. We propose a novel method that can automatically diagnose intracranial hematomas by combining machine vision and knowledge discovery techniques. The skull on the CT slice is located and the depth of each intracranial pixel is labeled. After normalization of the pixel intensities by their depth, the hyperdense area of intracranial hematoma is segmented with multi-resolution thresholding and region-growing. We then apply C4.5 algorithm to construct a decision tree using the features of the segmented hematoma and the diagnoses made by physicians. The algorithm was evaluated on 48 pathological images treated in a single institute. The two discovered rules closely resemble those used by human experts, and are able to make correct diagnoses in all cases.

    To carry out a retrospective study of the clinical features of patients with intrauterine hematoma in the second and third trimesters, and discuss the risk factors for poor pregnancy outcomes. A total of 398 patients who underwent routine examination in our hospital from January 2011 to December 2015 were classified into normal pregnancy (NP) group (N = 265) and adverse pregnancy (AP) group (N = 133), according to their pregnancy outcomes. Maternal clinical demographics, gestational age, location of hematoma, volume of hematoma, and accompanying contraction and vaginal bleeding were recorded. The average age of pregnant women in the NP and AP groups was 28.25 ± 4.06 and 29.5 ± 5.06 years, respectively (p = 0.007). Gestational age at first detection of hematoma was 15.11 ± 5.13 weeks in the NP group compared with 21.22 ± 8.25 weeks in the AP group (p < 0.001). In the AP group, the incidence of retroplacental hematoma (54.1%) and palpable contractions (62.8%) was significantly higher than in the NP group (25.7% and 12.1%, respectively; p < 0.01). However, similar maternal parity or history of delivery, volume of hematoma and incidence of vaginal bleeding were found. Intrauterine hematoma in the second and third trimesters is a sign of pathological pregnancy, resulting in adverse outcomes. Maternal age, gestational age at first diagnosis, location of hematoma and accompanying contraction are risk factors for poor pregnancy outcomes.

    Objective Aneurysm clipping and simultaneous hematoma evacuation through open craniotomy is traditionally recommended for ruptured cerebral aneurysms accompanied by intracerebral or intrasylvian hemorrhages. We report our experience of adapting a less invasive treatment strategy in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms, where the associated ruptured cerebral aneurysms were managed by endovascular coil embolization, followed by stereotactic aspiration of hematomas (SRH) using urokinase. Materials and Methods We retrospectively analyzed 112 patients with ruptured cerebral aneurysms. There were accompanying intracerebral or intrasylvian hemorrhages in 36 patients (32.1%). The most common site for these ruptured aneurysms was the middle cerebral artery (MCA) (n = 15; 41.6%). Endovascular coil embolization followed by SRH using urokinase was performed in 9 patients (25%). Results In these 9 patients, the most common site of aneurysms was the MCA (n = 3; 33.4%); the hematoma volume ranged from 19.24 to 61.68 mL. Four patients who were World Federation of Neurological Surgeons (WFNS) grade-IV on admission, achieved favorable outcomes (Glasgow Outcome Score [GOS] 4 or 5) at 6-months postoperatively. In the five patients who were WFNS grade-V on admission, one achieved a favorable outcome, whereas 4 achieved GOS scores of 2 or 3, 6-months postoperatively. There was no mortality. Conclusion If immediate hematoma evacuation is not mandated by clinical or radiological signs of brain herniation, a less invasive strategy, such as endovascular coil embolization followed by SRH using urokinase, may be a good alternative in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms.

    In (helicopter) emergency medical services, (H)EMS, the prehospital detection of intracranial hematomas should improve patient care and the triage to specialized neurosurgical hospitals.

    In (helicopter) emergency medical services, (H)EMS, the prehospital detection of intracranial hematomas should improve patient care and the triage to specialized neurosurgical hospitals. Recently, noninvasive detection of intracranial hematomas became possible by applying transcranial near infrared spectroscopy (NIRS). Herein, second-generation devices are currently available, for example, the Infrascanner 2000 (Infrascan), that appear suited also for prehospital (H)EMS applications.

    Spinal epidural hematoma (SEH) is an uncommon disorder, and chronic SEHs are rarer than acute SEHs. However, there is few reported involving the bone change of the vertebral body in chronic SEHs. We present a case report of lumbar epidural hematoma that required differentiation from extramedullary spinal tumors by a long process because the CT scan revealed scalloping of the vertebral body and review the relevant literature. A 78-year-old man had experienced a gradual onset of low back pain and excruciating pain in both legs. Lumbar MRI on T1-weighted images revealed a space-occupying lesion with a hyperintense signal relative to the spinal cord with no enhancement on gadolinium adminisration. Meanwhile, T2-weighted images revealed a heterogeneous intensity change, accompanying a central area of hyperintense signals with a hypointense peripheral border at the L4 vertebra. Moreover, the CT scan demonstrated scalloping of the posterior wall of the L4 vertebral body which is generally suspected as the CT finding of spainal tumor. During the epidural space exploration, we found a dark red-colored mass surrounded by a capsular layer, which was fibrous and adhered to the flavum and dura mater. Microscopic histological examination of the resected mass revealed a mixture of the relatively new hematoma and the hematoma that was moving into the connective tissue. Accordingly, the hematoma was diagnosed as chronic SEH. The particular MRI findings of chronic SEHs are helpful for making accurate preoperative diagnoses of this pathology.

    Chronic intradiploic hematoma was first described by Chorbski and Davis in 1934. To date, only twelve cases have been reported in the literature. Chronic intradiploic hematomas have also been described as non-neoplastic cysts of the diploe, traumatic cysts, and giant cell repetitive granulomas. The term chronic intradiploic hematoma was coined by Sato et al. in 1994. Case 1: a 16-year-old male presented with a non-tender scalp swelling on the right fronto-orbital region. Computed tomography (CT) scans showed an intraosseous isodense lesion with surrounding sclerosis. Magnetic resonance imaging (MRI) results revealed an intradiploic mass with homogeneous cystic and abnormal signal intensities. Case 2: a 64-year-old male presented with a 6-month history of headaches and visual disturbances. CT scans showed an isodense lesion with surrounding sclerosis in the posterolateral left orbit. MRI results revealed a hypointense lesion on both the T1weighted and T2-weighted images of the posterolateral left orbit. Although rarely seen, the presence of a benign chronic hematoma should be considered as part of the differential diagnosis for each intradiploic mass lesion. When taking the medical history, all patients with such mass lesions should be asked about previous minor or major head traumas. Due to the possibility of progressive growth, surgical excision of an intradiploic hematoma is recommended after radiological diagnosis of the condition.

    We evaluated the timing and predictors of surgical intervention for intracranial arteriovenous malformations (AVM) with hematoma. A ruptured intracranial AVM with hematoma is an emergency condition, and the optimal timing for surgical intervention is not well understood. In addition, the outcome predictors of surgical intervention have rarely been reported. We identified and analyzed 78 patients treated with microsurgical resection for pathologically proven AVM at Louisiana State University Health in Shreveport from February 1992 to December 2004. All 78 patients were diagnosed with ruptured AVM before surgery. The independent variables, including patient demographics, timing of surgery, location of the AVM and comorbidities were analyzed to assess outcome. The results of this series revealed that surgical intervention after 48hours resulted in poor outcomes for patients with hematoma, following a ruptured AVM. Several other prognostic factors, including younger age (11-40years), Spetzler-Martin Grade I and II, and AVM in a supratentorial location, had significant positive effects on outcomes. However, hypertension, smoking, and a prior embolization showed significant negative effects on outcomes after surgery. The multiple logistic regression analyses also revealed that the timing of surgical intervention had a significant effect on outcomes in patients with hematoma following ruptured AVM. Early intervention is the key to success in these patients. Published by Elsevier Ltd.

    Hematoma expansion is related to poor outcome in spontaneous intracerebral hemorrhage (ICH). Recently, a non-enhanced computed tomography (CT) based finding, termed the 'satellite sign', was reported to be a novel predictor for poor outcome in spontaneous ICH. However, it is still unclear whether the presence of the satellite sign is related to hematoma expansion. Initial computed tomography angiography (CTA) was conducted within 6h after ictus. Satellite sign on non-enhanced CT and spot sign on CTA were detected by two independent reviewers. The sensitivity and specificity of both satellite sign and spot sign were calculated. Receiver-operator analysis was conducted to evaluate their predictive accuracy for hematoma expansion. This study included 153 patients. Satellite sign was detected in 58 (37.91%) patients and spot sign was detected in 38 (24.84%) patients. Among 37 patients with hematoma expansion, 22 (59.46%) had satellite sign and 23 (62.16%) had spot sign. The sensitivity and specificity of satellite sign for prediction of hematoma expansion were 59.46% and 68.97%, respectively. The sensitivity and specificity of spot sign were 62.16% and 87.07%, respectively. The area under the curve (AUC) of satellite sign was 0.642 and the AUC of spot sign was 0.746. (P=0.157) CONCLUSION: Our results suggest that the satellite sign is an independent predictor for hematoma expansion in spontaneous ICH. Although spot sign has the higher predictive accuracy, satellite sign is still an acceptable predictor for hematoma expansion when CTA is unavailable. Copyright © 2017 Elsevier B.V.

    Chronic subdural hematoma (CSDH) is an inflammatory angiogenic disease. It is believed that vascular endothelial growth factor (VEGF) plays an important role in pathological CSDH angiogenesis. In this study, magnetic resonance imaging (MRI) results were used to assign 115 primary CSDH patients to four MRI types. The four MRI types are described as follows: type 1 (T1-weighted low, T2-weighted low), type 2 (T1-weighted high, T2-weighted low), type 3 (T1-weighted mixed, T2-weighted mixed), and type 4 (T1-weighted low/high, T2-weighted high). The four MRI types were then correlated with CSDH stage and patient hematoma fluid and serum VEGH concentrations that were measured using an enzyme-linked immunosorbent assay (ELISA). Neurological status was assessed by Markwalder scoring at admission and six-month follow-up. The mean VEGF concentration was significantly higher in CDSH hematoma fluid samples than in patient sera (p<0.01). In unilateral CSDH hematoma fluid samples, VEGF concentration was highest in type 1 (21,613.5±1473.3pg/ml), next highest in type 2 (18,071.8±1737.1pg/ml), lower in type 3, and lowest in type 4 patients (13,153.7±3854.4pg/ml, 7265.7±726.2pg/ml, respectively). High VEGF concentrations strongly correlated with MRI type (unilateral CSDH group r=0.838, bilateral CSDH group r=0.851, p<0.01). Moreover, higher hematoma fluid VEGF concentrations correlated with markedly higher recurrence in type 1 (3/19, 15.8%) vs. type 4 unilateral CSDH patients (1/27, 3.7%). The present study reports a significant correlation between CSDH hematoma fluid VEGF concentration and MRI results. Therefore, MRI results could be used to predict hematoma fluid VEGF concentrations in CSDH patients. Copyright © 2017 Elsevier B.V. All rights reserved.

  19. Vaccum drainage system application in the management of operation-related non-regional epidural hematoma

    PubMed Central

    2013-01-01

    Background Epidural intracranial hematoma is one of the most common complications of surgeries for intracranial tumors. The non-regional epidural hematoma is related to severe fluctuation of the intracranial pressure during the operation. The traditional management of hematoma evacuation through craniotomy is time-consuming and may aggravate intracranial pressure imbalance, which causes further complications. We designed a method using vaccum epidural drainage system, and tried to evaluate advantage and the disadvantage of this new technique. Methods Seven patients of intracranial tumors were selected. All of the patients received tumor resection and intra-operative non-regional epidural hematoma was confirmed through intra-operative ultrasound or CT scan. The vaccum drainage system was applied. Another ten patients who received craniotomy for intra-operative non-regional epidural hematoma evacuation were selected as comparison. Regular tests, like serial CT scan, were performed afterward to evaluate the effectiveness and to help deciding when to remove the drainage system. Results The vaccum drainage method was effective in epidual hemotoma clearance and prevented recurrent epidural hemorrhage. The drainage systems were removed within 4 days. All of the patients recovered well. No complications related to the drainage system were observed. Conclusions Compared to the traditional craniotomy, the new method of epidural hemoatoma management using vaccum epidural drainage system proved to be as effective in hematoma clearance, and was less-invasive and easier to perform, with less complication, shorter hospitalization, less economic burden, and better prognosis.

    To discuss the pathologic mechanism of subacute subdural hematoma (sASDH). Three typical cases of sASDH were reported, and related literature in Chinese published in the past 15 years was reviewed. Intervals from onset of acute subdural hematoma to surgery or symptom deterioration resulting in sASDH were 12.5-15.5 days (mean 14.1 days). Delayed liquefaction of hematoma clots occurred in all 3 reported cases. One patient achieved good curative effect after administration of dexamethasone, and another patient relapsed owing to poor drainage after evacuation of hematoma. The conversion of acute subdural hematoma to sASDH is an inflammatory reaction process with very regular in time, and it is speculated that the pathologic mechanism may be a delayed hypersensitivity reaction. Antigen released during the liquefaction process of blood clot, with subdural neomembrane cells as antigen-presenting cells, is presented to the T lymphocytes released from the capillaries in the neomembrane and forms sensitized T lymphocytes. When the subsequent antigen is released from the blood clots with a delayed liquefaction and is exposed to sensitized T lymphocytes, the delayed hypersensitivity process occurs.

    The computed tomography angiography (CTA) spot sign is a validated predictor of hematoma expansion and poor outcome in supratentorial intracerebral hemorrhage (ICH), but patients with brainstem ICH have typically been excluded from the analyses. We investigated the frequency of spot sign and its relationship with hematoma expansion and outcome in patients with primary pontine hemorrhage (PPH). We performed a retrospective analysis of PPH cases obtained from a prospectively collected cohort of consecutive ICH patients who underwent CTA. CTA first-pass readings for spot sign presence were analyzed by two trained readers. Baseline and follow-up hematoma volumes on non-contrast CT scans were assessed by semi-automated computer-assisted volumetric analysis. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive and negative likelihood ratio, and accuracy of spot sign for prediction of in-hospital mortality were calculated. 49 subjects met the inclusion criteria of whom 11 (22.4 %) showed a spot sign. In-hospital mortality was higher in spot sign-positive versus spot sign-negative subjects (90.9 vs 47.4 %, p = 0.020). Spot sign showed excellent specificity (95 %) and PPV (91 %) in predicting in-hospital mortality. Absolute hematoma growth, defined as parenchymal and intraventricular hematoma expansion of any amount, was significantly higher in spot sign-positive versus spot sign-negative subjects (13.72 ± 20.93 vs 3.76 ± 8.55 mL, p = 0.045). As with supratentorial ICH, the CTA spot sign is a common finding and is associated with higher risk of hematoma expansion and mortality in PPH. This marker may assist clinicians in prognostic stratification.

    Mediastinal hematoma extending along the pulmonary artery is a rare complication of Stanford type A classic (double-barreled) aortic dissection. Rupture from the posterior aspect of the aortic root penetrates the shared adventitia of the aorta and pulmonary artery. From this location, hematoma can spread along the adventitial planes of the pulmonary arteries out into the lungs. We report a case of ruptured intramural hematoma of the aorta (IMH) extending along the pulmonary artery. To our knowledge, this finding in patients with IMH has not been reported in the literature.

    Most symptomatic chronic subdural hematomas are treated by subdural drainage. However, a subperiostal (i.e., extracranial) passive closed-drainage system in combination with double burr hole trepanation is used at our institution. Therefore, we wanted to analyze our results and compare them with the alternate treatment strategies reported in the current literature. In a retrospective single-center study, we analyzed the data of all patients undergoing double burr hole trepanation with a subperiostal passive closed-drainage system. Data analysis included general patient data, complications, postoperative seizure rate, and outcome. One hundred forty-seven patients underwent surgery for 183 symptomatic chronic subdural hematomas. The perioperative mortality rate was 3.4%. Hematoma persistence or recurrence occurred in 13.1% of the cases. The postoperative seizure rate was 6.6%, and the infection rate was 1.6%, including 3 cases of superficial wound infection and 1 case with deep infection. The reintervention rate was 9.3%, including trepanation in 8.2% of the patients and craniotomy in 1.1%. The overall complication rate was 10.9%. Double burr hole trepanation combined with a subperiostal passive closed-drainage system is a technically easy, highly effective, safe, and cost-efficient treatment strategy for symptomatic chronic subdural hematomas. The absence of a drain in direct contact with the hematoma capsule may moderate the risk of postoperative seizure and limit the secondary spread of infection to intracranial compartments.

     Liquid posterior fossa epidural hematoma (LPFEH) following head trauma is uncommon, and very few such cases have been described in the literature. Eight patients with this entity and their treatments are presented here.  We performed a single-institution retrospective analysis of all patients with diagnosed LPFEH over a 3-year period. Collected data included clinical history, laboratory results, treatment, and review of all imaging studies performed.  Eight pediatric cases were identified with imaging findings consistent with LPFEH; no adult case was identified. Enlargement of ventricles appeared on computed tomography (CT) in six cases, and secondary epilepsy onset occurred in three cases with severe dilated ventricles. Routine hematologic and coagulation tests failed to disclose anemia or abnormal coagulation in each case. Five patients underwent burr-hole drainage of the hematoma and recovered completely. Conservative therapy was adopted in three patients for small hematomas, and hematoma enlargement was not observed in the follow-up CT scans.  LPFEH is a rare subtype of traumatic epidural hematoma specifically recognized in the pediatric population. Minimally invasive burr-hole drainage is a feasible procedure for the patient with evident space-occupying effect. Coagulation dysfunction or low hemoglobin as a possible contributing factor and its role in formation of LPFEH was excluded. Georg Thieme Verlag KG Stuttgart · New York.

    A case report and review of literature. We report on a patient with traumatic spinal subdural hematoma after vigorous back massage while on vacation. Traumatic spinal subdural hematoma is extremely rare, and to our knowledge, this is the first case reported after violent back massage. We emphasize a high index of suspicion for early recognition and treatment for a good neurological recovery. A 41-year-old male was brought to our hospital with severe back pain, motor and sensory impairments of the bilateral lower extremities, and urinary dysfunction after vigorous back massage. Magnetic resonance images revealed an acute spinal subdural hematoma in the thoracolumbar region. After careful monitoring of his neurological status, the patient was successfully managed with conservative treatment. After 2 weeks of hospitalization, complete motor power recovery was achieved with only minor sensory deficit. At a follow-up of more than 12 months, the patient has no residual neurological deficits. Spinal subdural hematoma secondary to physical trauma is quite rare. This case brings new information that traumatic spinal subdural hematoma can be caused by violent massage. N/A.

    Spontaneous retroperitoneal hematoma (SRH) is a severe and potentially fatal complication of anticoagulation therapy. We describe a case of fatal spontaneous massive retroperitoneal hematoma in a female patient receiving bridging therapy with enoxaparin for atrial fibrillation. Physicians should be cautious when prescribing enoxaparin in elderly patients, in patients with impaired renal function, and in patients receiving concomitant oral anticoagulants. Emergency physicians should always consider SRH in the differential diagnosis in patients under enoxaparin therapy presenting with abdominal pain. Computed tomographic scan is the imaging modality of choice for evaluating SRH. Early diagnosis and aggressive treatment are of paramount importance as SRH is associated with high mortality and morbidity rates.

    Acute epidural hematoma (AEDH) occurring as a result of traumatic head injury constitutes one of the most critical emergencies in neurosurgery. However, there are only several reports that show the rapid disappearance of AEDH without surgical intervention. We suggest redistribution of hematoma through the overlying skull fractures as the mechanism of rapid disappearance of AEDH. A 13-year-old female fell from a height of about 2 m and presented with mild headache. A computed tomography (CT) scan performed 4 hours after the injury revealed an AEDH with an overlying fracture in the right temporal region and acute small hemorrhagic contusion in the left frontal region. A repeat CT scan 16 hours after injury revealed that the AEDH had almost completely disappeared and showed an increase in the epicranial hematoma. The patient was discharged 10 days after injury with no neurological deficits. This case is characterized by the rapid disappearance of an AEDH associated with an overlying skull fracture. We believe that the rapid disappearance of the AEDH is due to the redistribution of the hematoma, rather than its resolution or absorption, and fracture plays a key role in this process.

    Secondary brain injury is the main cause of mortality from traumatic brain injury (TBI). One hallmark of TBI is intracranial hemorrhage, which occurs in 40-50% of severe TBI cases. Early identification of intracranial hematomas in TBI patients allows early surgical evacuation and can reduce the case fatality rate of TBI. As pre-hospital care is the weakest part of Chinese emergency care, there is an urgent need for a capability to detect brain hematomas early. In China, in addition to preventing injuries and diseases in military staff and in enhancing the military armed forces during war, military medicine participates in actions such as emergency public health crises, natural disasters, emerging conflicts, and anti-terrorist campaigns during peacetime. The purpose of this observational study is to evaluate in the Chinese military general hospital the performance of a near-infrared (NIR)-based portable device, developed for US Military, in the detection of traumatic intracranial hematomas. The endpoint of the study was a description of the test characteristics (sensitivity, specificity, and positive and negative predictive values [NPV]) of the portable NIR-based device in identification of hematomas within its detection limits (volume >3.5 mL and depth <2.5 cm) compared with computed tomography (CT) scans as the gold standard. The Infrascanner Model 2000 NIR device (InfraScan, Inc., Philadelphia, PA, USA) was used for hematoma detection in patients sustaining TBI. Data were collected in the People's Liberation Army General Hospital in Beijing using the NIR device at the time of CT scans, which were performed to evaluate suspected TBI. One hundred and twenty seven patients were screened, and 102 patients were included in the per protocol population. Of the 102 patients, 24 were determined by CT scan to have intracranial hemorrhage. The CT scans were read by an independent neuroradiologist who was blinded to the NIR measurements. The NIR device demonstrated

    Gait abnormalities have been seen in patients with Parkinson disease or Parkinson-like (P-L) disorders and cervical spinal stenosis. Acute presentation of P-L symptoms has been reported in 24 cases caused by chronic subdural hematomas with 11 cases due to bilateral chronic subdural hematomas. When a patient also presents with cervical spinal stenosis, the correct therapeutic decision between P-L disorders and myelopathy is challenging. An 80-year-old male presented with a 2-week history of weakness in his left leg. A few days before presentation, his gait had deteriorated quite dramatically. Neurologic examination showed mild leg weakness, hyperreflexia, and a gait that was slow and wide based, at times festinating but with relatively spared arm movement. He also had masked facial features with increased tone in his extremities. Magnetic resonance imaging of the cervical spine showed cervical stenosis at C5-6, and computed tomography of the head showed large bilateral subdural hematomas. The subdural hematomas were drained. Immediate improvement in his symptoms was observed with complete resolution by his third month of follow-up. The patient never had a history of Parkinson disease. This paper reports for the first time a patient who presented with acute P-L symptoms and cervical myelopathy with findings of both bilateral chronic subdural hematomas and cervical spinal stenosis. The decision to drain the subdural hematoma in our case resulted in full recovery of the patient's gait and other extrapyramidal symptoms. This paper reviews the literature on reversible P-L symptoms caused by bilateral chronic subdural hematomas. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objective Chronic subdural hematoma (cSDH) is common condition in neurosurgical field. It is difficult to select the treatment modality between the surgical method and the conservative method when patients have no or mild symptoms. The purpose of this study is to provide a suggestion that the patients could be cured with conservative treatment modality. Methods We enrolled 16 patients who had received conservative treatment for cSDH without special medications which could affect hematoma resolution such as mannitol, steroids, tranexamic acid and angiotensin converting enzyme inhibitors. The patients were classified according to the Markwalder's Grading Scale. Results Among these 16 patients, 13 (81.3%) patients showed spontaneously resolved cSDH and 3 (18.7%) patients received surgery due to symptom aggravation and growing hematoma. They were categorized into two groups based on whether they were cured with conservative treatment or not. The first group was the spontaneous resolution group. The second group was the progression-surgery group. The mean hematoma volume in the spontaneous resolution group was 43.1 mL. The mean degree of midline shift in the spontaneous resolution group was 5.3 mm. The mean hematoma volume in the progression-surgery group was 62.0 mL. The mean degree of midline shift in the second group was 6 mm. Conclusion We suggest that the treatment modality should be determined according to the patient's symptoms and clinical condition and close observation could be performed in patients who do not have any symptoms or in patients who have mild to moderate headache without neurological deterioration.

    Patient: Female, 68 Final Diagnosis: Mediastinal hematoma Symptoms: Agitation • severe hemodynamic instability • severe respiratory distress Medication: — Clinical Procedure: Cardiopulmonary resuscitation • reintubation • thoracic drain Specialty: Surgery Objective: Diagnostic/therapeutic accidents Background: We report a case of surgical central venous port system implantation using Seldinger’s technique with a life-threatening mediastinal hematoma due to the perforation of the superior vena cava. Case Report: A 68-year-old woman was admitted to our institution for port implantation. Open access to the cephalic vein and 2 punctures of the right subclavian vein were unsuccessful. Finally, the port catheter could be placed into the superior vena cava using Seldinger’s technique. As blood aspiration via the port catheter was not possible, fluoroscopy was performed, revealing mediastinal contrast extravasation without contrasting the venous system. A new port system could be placed in the correct position without difficulties. After extubation, the patient presented with severe respiratory distress and required consecutive cardiopulmonary resuscitation and reintubation. The CT scan showed a significant hematoma in the lower neck and posterior mediastinum with tracheal compression. We assumed a perforation of the superior vena cava with the tip of the guidewire using Seldinger’s technique. Long-term intensive treatment with prolonged ventilation and tracheotomy was necessary. The port system had to be subsequently explanted due to infection. Conclusions: Mediastinal hematoma is a rare but life-threatening complication associated with central venous catheterization using Seldinger’s technique. Perforation occurs most often during central venous catheterization in critical care. Mediastinal hematoma is an example of a mechanical complication occurring after central venous catheterization, which has been described only a few times in the literature to

    The use of fragmentation due to shock- waves as a treatment of urinary stone was one of the most important therapeutics findings in the history of urology. It's the first election treatment for most of the calculus at renal and urethral location due to the fact that it is a low invasive treatment and it has a few number of complications, but this method also has a few negative side effects, it can caused a more or less important traumatic lesion at the organs which crosses the shock-waves, including the kidney where it can caused a small contusion or renal hematoma with different resolution and treatment. We reviewed 4815 extracorporeal shock-wave lithotripsy that we performed in our department in which we found six cases with subcapsular and perirenal hematoma which we followed up and treated. After the urological complications (pain, obstruction and infection) the renal and perirenal hematic collections are the most frequent adverse effects of shock-waves used in lithotripsy, these are related to the power of energy used and patient age. Between the years 1992-2007 we performed 4.815 extracorporeal shock-wave lithotripsy finding seven cases of severe hematoma, less then 1%. Treatment of these complications is usually not aggressive though sometimes it is necessary to perform surgical drainage and even nephrectomy.

    Organizing hematomas of the paranasal sinuses are diagnostic dilemmas clinically and radiographically, mimicking benign or malignant neoplastic processes and causing patients and clinicians undue worry regarding these diagnoses. Diagnostic criteria for correctly identifying these lesions are not well known. A retrospective case series of 7 patients with sinonasal organizing hematoma was studied. Radiographic imaging, clinical characteristics, and pathology were reviewed for new insights. Three patients presented with a primary complaint of epistaxis, 4 had masses visible on nasal endoscopy, and 2 had vascular malformations or small hemangiomas adjacent to the mass found on final pathology. Biopsy of these masses were consistently nondiagnostic prior to complete resection. The most diagnostic findings were "shells" of T2 hypointensity on magnetic resonance imaging (MRI) surrounding the lobules of each of the masses. These correspond to rims of fibrosis at the periphery of the lobules on pathology. Areas of fresh hemorrhage are located at the center of these lobules. Sinonasal organizing hematomas are rare lesions of the paranasal sinuses whose clinical characteristics lead to misdiagnoses of benign or malignant neoplasms. Endoscopy, preoperative biopsy, and computed tomography (CT) imaging do not lend helpful information in differentiating these lesions from more worrisome neoplastic processes. However, MRI can lead to positive diagnosis by recognizing the distinct outer rims of T2 hypointensity typically seen in these lesions. © 2013 ARS-AAOA, LLC.

    Symptomatic chronic subdural hematoma (scSDH) is one of the most frequent diseases in neurosurgical practice, and its incidence is increasing. However, treatment modalities are still controversial. The aim of this retrospective single-center study is to compare for the first time two surgical methods in the treatment of subdural hematoma that have been proven to be efficient in previous studies in a direct comparison. We analyzed the data of 143 scSDHs in 113 patients undergoing surgery for subdural hematoma with placement of subperiosteal or subdural drainage after double burr-hole trepanation for hematoma evacuation. Overall, there were no statistically significant differences regarding general patient characteristics, preoperative and postoperative symptoms, postoperative hematoma remnant, rates of recurrences, mortality, complications, and outcome at discharge and at 3-month follow up between the groups. There was a close to significant tendency of lower mortality after placement of subperiosteal drainage system and a tendency towards lower rate of recurrent hematoma after placement of subdural drainage system. Our study shows for the first time a direct comparison of two mainly used surgical techniques in the treatment of scSDH. Both methods proved to be highly effective, and general patient data, complications, outcome and mortality of both groups are equal or superior compared with previously published series. Because there is a clear tendency to less mortality and fewer serious complications, treatment with double burr-hole trepanation, irrigation, and placement of subperiosteal drainage is our treatment of choice in patients with predictable high risk of complications.

    Endocapsular hematoma has previously been described as a cataract surgery complication more commonly observed in eyes receiving a combined cataract and glaucoma surgery. However, it can also be a rare form of ocular bleed following thrombolysis with streptokinase. A 65-year-old diabetic male presented to us with complain of sudden painless diminution of vision in his left eye, which he developed while he was being thrombolysed with streptokinase administered intravenously for an episode of acute myocardial infarct. On examination, left eye was pseudophakic with collection of blood in the capsular bag (Endocapsular hematoma). Endocapsular hematoma can be a rare form of ocular bleeding complicated by thrombolysis. Reporting this case becomes more relevant in the present era with increasing number of patients suffering from ischemic heart disease and likely to undergo thrombolysis.

    Hematoma expansion is related to unfavorable prognosis in intracerebral hemorrhage (ICH). The black hole sign is a novel marker on non-contrast computed tomography for predicting hematoma expansion. However, its predictive values are different in previous studies. Thus, this meta-analysis was conducted to evaluate the predictive significance of the black hole sign for hematoma expansion in ICH. A systematic literature search was performed. Original researches on the association between the black hole sign and hematoma expansion in ICH were included. Sensitivity and specificity were pooled to assess the predictive accuracy. Summary receiver operating characteristics curve (SROC) was developed. Deeks' funnel plot asymmetry test was used to assess the publication bias. Five studies with a total of 1495 patients were included in this study. The pooled sensitivity and specificity of the black hole sign for predicting hematoma expansion were 0.30 and 0.91, respectively. The area under the curve was 0.78 in SROC curve. There was no significant publication bias. This meta-analysis shows that the black hole sign is a helpful imaging marker for predicting hematoma expansion in ICH. Although the black hole sign has a relatively low sensitivity, its specificity is relatively high. Copyright © 2018 Elsevier Inc. All rights reserved.

    The aim of this study was to assess the possibility of revealing intracerebral hematomas (ICH), using MRI, within the first hours after onset and to determine their MRI semiotics features. Thirty animals with experimental ICH were studied. A method of two-stage introduction of autologous blood was used to develop ICH as human spontaneous intracranial hematomas. Within 3-5h after blood introduction to the rat brain. The control MRI was performed in the 3rd and 7th days after blood injections. ICH were definitely identified in the first MRI scans. The MRI semiotics features of acute ICH and their transformations were assessed. The high sensitivity of MRI to ICH as well as the uniform manifestations in all animals were shown. In conclusion, the method has high specificity for acute ICH detection.

    To compare the outcome after surgery for chronic subdural hematoma when the drain is placed in subdural space or subgaleal space. Quasi experimental study. Combined Military Hospital, Lahore, from July 2015 to June 2016. Patients with chronic subdural hematoma of both genders and age, ranging between 55 to 85 years, were included. Patients on antiplatelet/anticoagulant therapy and acute on chronic subdural hematoma were excluded. Patients were divided in two equal groups each depending on whether drain was placed in subgaleal space (Group 1), and subdual space (Group 2), (n=31 patients each). Patients were positioned flat in bed after surgery. Clinical and radiological parameters and clinical outcome were compared between the two groups. Statistical test with significance of p <0.05 was utilized using Statistical Package of Social Sciences (SPSS version 17). Median age of the 62 patients was 72 ±12.5 years. Headache was the most common symptom reported in both groups, (n=47,75.8%) patients. Median thickness of hematoma was 15 ±6.5 mm. Patients with subdural drain placement had more complications such as pneumocephalus 11 (35.4%) vs. 6 (19.3%), and intracerebral hemorrhage 4 (12.9%) vs. 2 (6.4%). Clinical outcome was good in both groups 27 (87%) in Group 1 and 28 (90%) in Group 2. Patients of both groups had good outcome after surgery. Complications like pneumocephalus and intracerebral hemorrhage were more common in subdural location of drain, though not reaching statistically significance level to favor one technique over another.

    Late intrahepatic hematoma is a rare complication of the transjugular intrahepatic portosystemic shunt (TIPS) procedure. We describe a patient with Budd-Chiari syndrome (BCS), who presented with a large inrahepatic hematoma 13 days after TIPS. Review of the literature reveals only two previous cases, both occurring in patients with BCS and presenting after a similar time interval. This potentially serious complication appears to be specific for TIPS in BCS.

  2. The roles of cellular and molecular components of a hematoma at early stage of bone healing.

    Bone healing is a complex repair process that commences with the formation of a blood clot at the injured bone, termed hematoma. It has evidenced that a lack of a stable hematoma causes delayed bone healing or non-union. The hematoma at the injured bone constitutes the early healing microenvironment. It appears to dictate healing pathways that ends in a regenerative bone. However, the hematoma is often clinically removed from the damaged site. Conversely, blood-derived products have been used in bone tissue engineering for treating critical sized defects, including fibrin gels and platelet-rich plasma. A second generation of platelet concentrate that is based on leukocyte and fibrin content has also been developed and introduced in market. Conflicting effect of these products in bone repair are reported. We propose that the bone healing response becomes dysregulated if the blood response and subsequent formation and properties of a hematoma are altered. This review focuses on the central structural, cellular, and molecular components of a fracture hematoma, with a major emphasis on their roles in regulating bone healing mechanism, and their interactions with mesenchymal stem cells. New angles towards a better understanding of these factors and relevant mechanisms involved at the beginning of bone healing may help to clarify limited or adverse effects of blood-derived products on bone repair. We emphasize that the recreation of an early hematoma niche with critical compositions might emerge as a viable therapeutic strategy for enhanced skeletal tissue engineering.

    We sought to use computed tomography (CT) data to support the correct differential diagnosis of patients with spontaneous intramural hematomas of the gastrointestinal tract, to aid in the clinical management of those using oral anticoagulants. Patient data were retrospectively analyzed and patients were divided into two groups. The first group contained 10 patients (5 females, 5 males, median age 65 years [range 35-79 years]) who had been diagnosed with spontaneous intramural hematomas of the gastrointestinal tract. The second group contained nine patients (5 females, 4 males, median age 41 years [range 24-56 years]) who exhibited intestinal wall thickening on CT, and who had been diagnosed with ulcerative colitis, Crohn's disease, ameboma, and lymphoma. The enhancement patterns in the CT images of the two groups were compared by an experienced and inexperienced radiologist. The differences in values were subjected to ROC analysis. Inter-observer variability was excellent (0.84) when post-contrast CT images were evaluated, as were the subtraction values (0.89). The subtracted values differed significantly between the two groups (p=0.0001). A cutoff of +31.5 HU was optimal in determining whether a hematoma was or was not present. Contrast enhancement of an intestinal wall hematoma is less than that of other intestinal wall pathologies associated with increased wall thickness. If the post-contrast enhancement of a thickened intestinal wall is less than +31.5 HU, a wall hematoma is possible. © Acta Gastro-Enterologica Belgica.

    Remote epidural hematoma (REDH) is an uncommon complication of decompressive craniectomy. Remote epidural hematomas of the parietal occiput region have been reported only rarely. We report a unique case of delayed-onset bilateral extensive straddle postsagittal sinus and bilateral lateral sinus parietal occiput REDH after decompressive craniectomy, of which volume was approximately 130 mL, with left deviating midline structures. The patient was immediately taken back to the operating room for evacuation of the REDH via bilateral parietal and occiput craniectomy. Postoperatively, serial computed tomographic scans performed 3 days later showed that the REDH had been completely evacuated. Two months later, the patient regained full consciousness and obtained a near-complete recovery except for right facial paralysis.

    Ruptured middle cerebral artery (MCA) aneurysms usually lead to subarachnoid hemorrhage (SAH), and several cases have shown concomitant intrasylvian or intracerebral hematomas. The objective of this study was to compare the clinical and radiographic characteristics with their different outcomes. The charts of 30 consecutive patients with ruptured MCA aneurysm-related intracranial hematoma were retrospectively reviewed. These patients were dichotomized into an intrasylvian hematoma (ISH) group and an intracerebral hematoma (ICH) group by the presence of intrahematomal contrast-enhancing vessel; for patients under open surgery, hematoma type was further confirmed by intraoperative observation. The characteristics were compared between these 2 groups (ie, age, gender, history of hypertension, history of smoking, systolic pressure at admission, hematoma volume, size and side of aneurysms, the angle between the pointing direction of the aneurysm and the MCA trunk [denoted as α], middle line shifting, treatment modality, and outcome). All the angles are measured in the anterior-posterior projection. In our series, only hematoma volume, the angle α, and the middle line shift showed statistical significance regarding prognosis between 2 hematoma groups. An angle α between 109.0°and 216.0° is associated with ISH, whereas aneurysm with an angle beyond this range indicates ICH. In our series, patients in the ICH group had a larger hematoma volume compared with the ISH patients (33.3 ± 17.6 vs. 11.5 ± 10.5; P = 0.002). There exists no statistical difference regarding prognosis between these 2 groups, even although there is a trend toward worse recovery for patients in the ISH group (Glasgow Outcome Scale score, 3.0 ± 1.3 vs. 3.8 ± 1.9; P = 0.07). In our series, the prognosis of patients with ICH was worse than that of patients with ISH. Early discrimination of these 2 types of hematoma helps to predict future outcome; an angle (between the pointing direction of

    Patients with sickle cell disease (SCD) may experience many complications of the central nervous system (CNS) including stroke, silent cerebral infarcts, and neuropsychological deficits. Cranial epidural hematoma is a rare but potentially serious complication. Case series of cranial epidural hematomas in children with SCD from three different institutions is considered, along with a literature review of cranial epidural hematomas in this population. Seven children with SCD with cranial epidural hematomas were identified from three different institutions. All patients were male and the age at presentation ranged from 10 to 18 years. Two patients presented with headache (28.6%), while the rest had no neurologic symptoms at presentation. Four patients required urgent neurosurgical intervention (57.1%) and one patient died (14.3%). A literature review identified 18 additional cases of cranial epidural hematomas in children with SCD. Of these, treatment ranged from supportive care to neurosurgical intervention. Twelve patients completely recovered (66.7%), one patient had long-term cognitive impairment (5.6%), and four patients died (22.2%). Combined with our data, cranial epidural hematomas have a mortality rate of 20.0%. Although rare, cranial epidural hematoma can be fatal and should be considered in patients with acute neurological symptoms. © 2016 Wiley Periodicals, Inc.

    Hematoma growth is a strong independent predictor of poor outcome after intracerebral hemorrhage. However, there is no gold standard to accurately predict hematoma growth. Several noncontrast computed tomographic markers associated with hematoma growth have been reported recently. Blend sign, which is a new marker, has been reported in several studies and seems a particularly promising marker but lacks a standardized evaluation so far. A systematic review of published literature on blend sign and hematoma growth and clinical outcomes was conducted. Systematic review of best practices was followed, and study quality was assessed. The 6 studies involved 1573 participants in this review. The prevalence of blend sign ranged from 8.70% to 38.46%. The sensitivity of blend sign to predict hematoma growth varied from 13.0% to 42.86%; the specificity varied from 88.51% to 95.5%. Blend sign showed lower sensitivity but superior specificity for prediction of hematoma growth. Four studies indicated that the presence of blend sign was an independent predictor of hematoma growth. Four studies showed that the prevalence of blend sign was significantly higher in patients with hematoma growth compared with those without hematoma growth (odds ratio, 9.33; 95% confidence interval, 5.20-16.74). There was an association between blend sign and hematoma growth, but this finding is tentative in light of the fact that the number of included studies was relatively small.

    Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included (International Classification of Diseases 10th Revision codes I61.0-I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with P<0.1 were included in a binary logistic regression model. The binary logistic regression model was adjusted for age, initial Glasgow Coma Score (GCS), the presence of intraventricular hemorrhage (IVH), and pre-ICH disability prior to ictus. In 8,421 patients with spontaneous ICH, pre-treatment with oral anticoagulants or antiplatelet agents was documented in 16.3% and 25.1%, respectively. Overall in-hospital mortality was 23.2%. In-hospital mortality was decreased in operatively treated patients compared to conservatively treated patients (11.6% versus 24.0%; P<0.001). Patients with antiplatelet pre-treatment had a significantly higher risk of death during the hospital stay after hematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24-4.97; P=0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79-1.09; P=0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.

    To evaluate the efficacy of dural tenting suture and epidural drainage in craniotomy. In 145 cases of intracranial lesions, dural tenting suture and epidural drainage were performed to prevent epidural hematoma. Postoperative computed tomography (CT) showed no epidural hematoma required surgery in both groups. Both dural tenting suture and epidural drainage are effective in preventing epidural hematoma. Hemostasis is the key step. Dural tenting suture without epidural drainage relieves psychological stress. It decreases the risk of intracranial infection and avoids some unusual complications.

  12. Predictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients

    2017-01-01

    Hematoma expansion (HE) occurs in approximately one-third of patients with intracerebral hemorrhage and leads to high rates of mortality and morbidity. Currently, contrast extravasation within hematoma, termed the spot sign on computed tomography angiography (CTA), has been identified as a strong independent predictor of early hematoma expansion. Past studies indicate that the spot sign is a dynamic entity and is indicative of active hemorrhage. Furthermore, to enhance the spot sign's accuracy of predicting HE, spot parameters observed on CTA or dynamic CTA were used for its quantification. In addition, spot signs detected on multiphase CTA and dynamic CTA are shown to have higher sensitivity and specificity when compared with simple standardized spot sign detection in recent studies. Based on the spot sign, novel methods such as leakage sign and rate of contrast extravasation were explored to redefine HE prediction in combination with clinical characteristics and spot sign on CTA to assist clinical judgment. The spot sign is an accepted independent predictor of active hemorrhage and is used in both secondary intracerebral hemorrhage and the process of surgical assessment for hemorrhagic risk in patients with ischemic stroke. Spot sign predicts patients at high risk for hematoma expansion. PMID:28852647

    We report the exceptional case of an encapsulated solid non-organized chronic subdural hematoma (SDH) in a 67-year-old woman that was admitted with acute hemiplegia followed by rapid deterioration in consciousness 5 months after a minor head trauma. Computed tomography (CT) showed an extracerebral biconvex shaped hyperdense mass that led to the misdiagnosis of an acute epidural hematoma. Urgent craniotomy revealed an encapsulated mass filled with solid fresh clot in the subdural space. Complete evacuation of this SDH, including both its inner and outer membranes, was achieved, and the patient recovered successfully. Histological analysis confirmed that the content of the hematoma corresponded to a newly formed clot that was enclosed between an inner membrane, composed of two collagen layers, and an outer membrane with a three layered structure. Chronic SDH may seldom present as an encapsulated solid non-organized lesion that consists of a fibrous capsule enclosing a fresh clot and lacking the thick fibrous septations that typically connect the inner and outer membranes of organized chronic SDH. This entity mimics the clinical course and radiological appearance of acute epidural hematomas and should be considered in the differential diagnosis of extracerebral hyperdense biconvex shaped lesions.

    BACKGROUND Early hematoma growth is associated with poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). The swirl sign (SS) and the black hole sign (BHS) are imaging markers in ICH patients. The aim of this study was to compare the predictive value of these 2 signs for early hematoma growth. MATERIAL AND METHODS ICH patients were screened for the appearance of the 2 signs within 6 h after onset of symptoms. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 2 signs in predicting early hematoma growth were assessed. The accuracy of the 2 signs in predicting early hematoma growth was analyzed by receiver-operator analysis. RESULTS A total of 200 patients were enrolled in this study. BHS was found in 30 (15%) patients, and SS was found in 70 (35%) patients. Of the 71 patients with early hematoma growth, BHS was found on initial computed tomography scans in 24 (33.8%) and SS in 33 (46.5%). The sensitivity, specificity, PPV, and NPV of BHS for predicting early hematoma growth were 33.8%, 95.3%, 80.0%, and 72.0%, respectively. The sensitivity, specificity, PPV, and NPV of SS were 46.5%, 71.3%, 47.0%, and 71.0%, respectively. The area under the curve was 0.646 for BHS and 0.589 for SS (P=0.08). Multivariate logistic regression showed that presence of BHS is an independent predictor of early hematoma growth. CONCLUSIONS The Black hole sign seems to be good predictor for hematoma growth. The presence of swirl sign on admission CT does not independently predict hematoma growth in patients with ICH.

    Study Design Case report and literature review. Objective Spinal subdural hematomas are rare events that often progress with severe neurologic deficits. Although there have been several case reports in the literature of spontaneous spinal subdural hematomas in the setting of anticoagulation, antiplatelet therapy, or coagulation disorders, the exact pathophysiology of such phenomena remains obscure. Methods We present the first report of a subdural hematoma after a percutaneous vertebroplasty and provide a comprehensive review on the anatomy of venous drainage of the vertebral bodies with emphasis on the possible effects of venous congestion caused by cement obstruction. Results Because the subdural hematoma occurred in the absence of major cement extravasation to the spinal canal and two levels above the site of the vertebroplasty, we discuss the possible role of venous congestion as the main etiologic factor leading to rupture of the fragile, valveless radiculomedullary veins into the subdural space. Conclusions The reported case supports a possible new pathophysiological scheme for the development of spinal subdural hematoma in which venous congestion plays a pivotal etiologic role. The reported findings suggests that future anatomical and histologic studies investigating the response of the radiculomedullary veins to congestive venous hypertension may shed new light into the pathophysiology of spinal subdural hematomas.

    Abdominal wall pathology is a frequently overlooked cause of acute abdomen. Increasing use of antiplatelet and anticoagulant therapies has led to an increase in the incidence of spontaneous rectus sheath hematoma (RSH). A high index of suspicion is needed for diagnosis as it can closely mimic other causes of acute abdomen. Herein, we report a case of RSH presenting with abdominal pain in which there was a significant delay in diagnosis. We wish to highlight the need to increase awareness among primary and emergency physicians about considering RSH in the initial differential diagnoses of abdominal pain. PMID:20411082

    2017-01-01

    Chronic expanding hematoma is characterized by continuous growth of a blood collection. We analyzed the clinical features of 7 patients with chronic expanding hematomas in the extremities, with an average age of 65.6 years. All lesions occurred in the lower extremities, with 4 seen in the thigh and 3 in the knee region. Six patients had subcutaneous hematomas, while 1 was deep-seated in the thigh. The magnetic resonance features of the lesion were compatible with those of a standard hematoma. A low signal intensity on T1- and T2-weighted imaging at the pseudocapsule was also characteristic. Cystic features were seen in 5 of 7 patients. All lesions were resected together with their pseudocapsule. In the subcutaneous lesions, it was necessary to resect adherent fascia, with or without involved skin. In the deep-seated thigh lesion, the common peroneal nerve was completely adherent to the pseudocapsule, a phenomenon from absence of the common peroneal nerve which appeared after resection. Chronic expanding hematomas of the extremities are predominantly located in the subcutaneous tissue of the lower extremity. The surrounding pseudocapsule is adherent to the adjacent tissues, and clinicians must be aware of this, especially when resecting a deep-seated lesion. PMID:28642872

    2017-01-01

    Abstract Rationale: We report on restoration of the ascending reticular activating system (ARAS), compressed by an intracerebral hematoma and perihematomal edema following a stroke. The restoration of the ARAS was demonstrated by diffusion tensor tractography (DTT). Patient concerns: In a 60-year-old male, a brain MRI taken at 2 weeks after the surgery showed a hematoma and perihematomal edema in the left posterolateral pons and cerebellum, which were markedly resolved on a brain MRI after 5 weeks. Diagnoses: Intraventricular hemorrhage. Interventions: Navigation-guided stereotactic drainage of a hematoma in the left cerebellum, comprehensive rehabilitative therapy, including hypersomnia medication (modafinil), physical therapy, and occupational therapy. Outcomes: His hypersomnia improved significantly with rehabilitation, with no daytime hypersomnia beginning 3 weeks after the surgery. On 2-week DTT, neither the neural tract of the left lower dorsal or ventral ARAS were reconstructed, but these neural tracts were wellreconstructed on 5-week DTT. Lessons: In conclusion, restoration of nonreconstructed neural tracts of the lower ARAS with the resolution of the hematoma and perihematomal edema was demonstrated in a stroke patient, using DTT.

    The clinical and endoscopic features of amyloid light-chain (AL) amyloidosis are diverse and mimic various other diseases. Endoscopically, few reports on submucosal hematomas of the gastrointestinal (GI) tract are available in the literature. Here, we report two cases of AL amyloidosis presenting as submucosal hematomas in the absence of clinical disease elsewhere in the body. The 2 cases were referred to our hospital because of hematochezia. The endoscopic findings in both cases were similar in submucosal hematoma formation. However, the clinical courses differed. In the first case, there was no evidence of systemic amyloidosis and the disease was conservatively managed. In the second case, the disease progressed to systemic amyloidosis and the patient died within a short time. We conclude that the endoscopic detection of a submucosal hematoma in the setting of GI bleeding should raise suspicion of AL amyloidosis. Referral to a hematologist should be done immediately for treatment while the involvement is limited to the GI tract. PMID:23125904

    Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

    Patients with acute or chronic subdural hematomas may present with rapidly deteriorating neurological function and are at risk for irreversible brainstem injury. In such cases, rapid surgical intervention is required to evacuate the hematoma and reverse critically elevated intracranial pressure. A variety of surgical drainage methods are in existence, none of which are clearly superior to the others. This report presents the case of a 74-year-old woman who suffered an acute-on-chronic subdural hematoma which was evacuated in the emergency department utilizing the subdural evacuating port system (SEPS). The SEPS provides for a minimally invasive technique to drain subdural hematomas and is advantageous in that it can be performed at the bedside. The SEPS is relatively simple to use and may be especially useful to emergency department staff in outlying areas where there is a shortage of neurosurgical coverage.

    Initial management strategies of chronic subdural hematoma (cSDH) are controversial and range from bedside twist-drill or burr-hole drainage to craniotomy with membranectomy (CWM). We aim to 1) perform a meta-analysis of the available data on the outcomes of CWM for treatment of cSDH in published English-language literature and 2) evaluate collective outcomes of CWM with respect to morbidity, mortality, and recurrence rates. A search of English-language literature performed in PubMed, Ovid, and Cochrane databases using key words ("subdural hematoma" or "chronic subdural hematoma") and ("membrane" or "membranectomy") from inception to December 2016 was conducted. Studies reporting outcomes of CWM in cSDH were included. Mortality, morbidity, follow-up duration, and recurrence rate data were extracted and analyzed. Pooled estimates and confidence intervals (CIs) were calculated for all outcomes using a random-effects model. Of 301 articles found, 17 articles containing 5369 patients met our eligibility criteria. Mean follow-up duration ranged from 1-30.8 months. Collective mean mortality and morbidity rates were 3.7% and 6.9%, respectively (95% CI 2-5.4% and 2.1-11.6%; P < 0.001 and P = 0.004). The collective mean recurrence rate was 7.6% (95% CI: 5%-10.2%; P < 0.001). Clinical data on outcomes of CWM in cSDH are limited to single institutional analyses, with considerable variation in recurrence rates and follow-up time. The rates we reported are comparable with the 5% mortality and 3%-12% morbidity rates and lower than the 10%-21% recurrence rate in the literature for burr holes or craniotomy without membranectomy. This meta-analysis provides an in-depth analysis of available data and reviews reported outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    Recurrent chronic subdural hematoma (CSDH) is not rare. Some studies have demonstrated the role of dexamethasone in the medical management of chronic subdural hematoma. However, no systematic study in the treatment of recurrent CSDH has been published. The aim of our study is to evaluate the efficacy and safety of dexamethasone in patients with recurrent CSDH. We retrospectively reviewed medical records of consecutive patients from July 2010 to September 2014. A total of 27 patients with symptomatic recurrent CSDH were included in the analysis. Follow-up for each patient consisted of computed tomography or magnetic resonance imaging every 28 days from admission to the resolution of hematoma. Data were collected on hematoma volume, complications, and outcome. Among the 27 patients, 3 patients with recurrent CSDH were only treated by burr hole surgery. Of the other 24 patients who primarily underwent dexamethasone treatment, 17 (70.8%) patients were treated successfully with medical treatment, whereas 7 patients required reoperation. Complications were noted in 3 (12.5%) patients (1 hyperglycemia, 1 urinary tract infection, and 1 pneumonia). There was 1 mortality (4.2%) for massive brain infarction. Twenty-one of the 24 patients (87.5%) recovered to their previous functional levels. There was no statistical significance in Fisher text between surgery and dexamethasone regarding success, complication, and functional recovery rate. Patients with recurrent CSDH can be treated successfully and safely with the nonsurgical medical treatment of dexamethasone. By use of this method, reoperation may be avoided.

    Chronic subdural hematoma (CSDH) is a common neurosurgical condition with an increasing incidence. Standard treatment of CSDHs is surgical evacuation. The objective of this study is to present a modification of standard burr-hole hematoma evacuation using a flexible endoscope and to assess the advantages and risks. Prospectively, 34 consecutive patients diagnosed with CSDH were included in the study. Epidemiological, clinical and radiographical data were collected and reviewed. All patients underwent a burr-hole evacuation of CSDH. A flexible endoscope was inserted and subdural space inspected during surgery. The surgeon was looking specifically for the presence of septations, draining catheter position and acute bleeding. Thirty-four patients underwent 37 endoscope-assisted surgeries. Presenting symptoms were hemiparesis (79%), decreased level of consciousness (18%), gait disturbances (15%), headache (12%), aphasia (6%), cognitive disturbances (6%) and epileptic seizure (3%). Average operative time was 43 min, and the average increase in operative time due to the use of the endoscope was 6 min. Recurrence rate was 8.8%, and clinical outcome was favorable (defined as mRS ≤ 2) in 97% of the cases. To our knowledge, the present cohort of 34 patients is the largest group of patients with CSDH treated using an endoscope. This technique allows decent visualization of the hematoma cavity while retaining the advantages of a minimally invasive approach under a local anesthesia. The main advantages are correct positioning of the catheter under visual control, identification of septations and early detection of cortex or vessel injury during surgery.

  7. Rivaroxaban-induced chest wall spontaneous expanding hematoma.

    2017-03-22

    Rivaroxaban is an oral direct Factor Xa inhibitor approved in the European Union and the United Sates for the single-drug treatment of several thromboembolic diseases in adults. Ιt has been evaluated in large phase III clinical trials and has been found to have similar efficacy and safety with standard therapy. Herein, is described a very rare case of a rivaroxaban-induced spontaneous expanding chest wall hematoma, that required surgical intervention, in a breast cancer patient. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 7) between the patient's development of hematoma and treatment with rivaroxaban. Physicians should be cautious when prescribing rivaroxaban in groups of patients associated with increased bleeding risk such as patients with impaired renal or hepatic function, hypertension, coronary heart disease, heart failure, patients with certain types of cancers and patients receiving concomitant medications which may alter the pharmacokinetic or pharmacodymamic parameters of rivaroxaban. Anticoagulant treatment should be tailored to each individual patient weighing the bleeding risk against the risk of recurrent thrombosis.

    Rectus sheath hematoma (RSH) is an uncommon cause of acute abdominal pain. It may mimic a wide variety of intraabdominal disorders thus frequently leading to delay in treatment, increased morbidity or even in an unnecessary surgery. This is a retrospective study of 10 patients with RSH who were treated in our department over a five-year period. There were 6 (60%) men and 4 (40%) women ranging in age from 38 to 86 years, with a mean age of 57.1 years. The most common clinical presentation was a palpable abdominal mass associated with abdominal pain. Computed tomography (CT) established the diagnosis in 100% of the cases. 4 patients had type I hematoma, 3 had type II hematoma and 3 had type III hematoma. Anticoagulation therapy was the most common predisposing factor. Conservative treatment was effective in 90% of the cases and in all cases of spontaneous RSHs in patients under anticoagulation therapy. One patient, who developed a very severe RSH following an abdominal injection of low-molecular-weight heparin (LMWH), underwent surgery. All patients with type III hematoma required blood transfusion. RSH should be considered in the differential diagnosis of the elderly patients under anticoagulation therapy presenting with acute abdominal pain and a palpable mass. CT is the diagnostic modality of choice. Conservative treatment is feasible in most cases. Early diagnosis is mandatory in order to avoid morbidity or unnecessary surgery. In order to prevent a traumatic RSH, trocar insertion under direct vision during laparoscopic surgery and careful attention in the abdominal administration of LMWH are essential.

  9. [Cerebral intraperenchymatous hematomas: surgical treatment not to start with].

    PubMed

    Roda, J M

    The surgical treatment of intraparenchymal hematomas is very controversial. To date, there has been no through analysis of the subject and neurological specialists need a broad study to indicate which patients should have surgical treatment and which is the surgical option which gives the best results with the least damage. In this paper, the author considers which patients should not have any operation, which should always be operated on and in which there is a relative indication for operation. The different techniques available, their advantages and disadvantages are briefly reviewed. In view of the results obtained to date, it is likely that in future the usual treatment for intraparenchymatous hematomas will be medical (not surgical) and aimed at the protection of surrounding tissue. When surgery is required, it should be as minimally invasive as possible.

    Calcified chronic subdural hematoma (CCSDH) is a rare disease for which no standard approach to treatment has been established. Reports covering both burr hole trepanation and craniotomy for CCSDH are rare. Furthermore, infection of CCSDH after the burr hole trepanation has not been reported in the literature. A 61-year-old man presented with left frontotemporoparietal CCSDH demonstrated on computed tomography (CT) scan. The patient underwent 2 separate burr hole trepanations with intraoperative irrigation and postoperative drainage. These procedures led to infection of the CCSDH. The patient eventually underwent an open craniotomy to provide complete removal of the hematoma. Owing to the complex contents of a CCSDH, burr hole trepanation cannot adequately drain the hematoma or relieve the mass effect. Craniotomy is a much more reliable approach for achieving complete resection of a CCSDH. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objective We wanted to demonstrate the temporal changes of the magnetic resonance imaging (MRI) findings in experimentally-induced intramuscular hematomas in rats and to correlate these data with the concurrent pathologic observations. Materials and Methods Intramuscular hematoma was induced in 30 rats. The MR images were obtained at 1, 4, 7 and 10 days and at 2, 3, 4, 6 and 8 weeks after muscle injury. The characteristic serial MRI findings were evaluated and the relative signal intensities were calculated. Pathologic specimens were obtained at each time point. Results On the T1-weighted imaging (T1WI), the intramuscular hematomas exhibited isointensity compared to that of muscle or the development of a high signal intensity (SI) rim on day one after injury. The high SI persisted until eight weeks after injury. On the T2-weighted imaging (T2WI), the hematomas showed high SI or centrally low SI on day one after injury, and mainly high SI after four days. A dark signal rim was apparent after seven days, which was indicative of hemosiderin on the pathology. The gradient echo (GRE) imaging yielded dark signal intensities at all stages. Conclusion Unlike brain hematomas, experimentally-induced intramuscular hematomas show increased SI on both the T1WI and T2WI from the acute stage onward, and this is pathologically correlated with a rich blood supply and rapid healing response to injury in the muscle. On the T2WI and GRE imaging, high SI with a peripheral dark signal rim is apparent from seven days to the chronic stage. PMID:21228942

    Objective: To report a successful conservative management in a case of spontaneous rectus sheath hematoma (SRSH) after Endovascular Aneurysmal Repair (EVAR) of infrarenal Abdominal Aortic Aneurysm (AAA). Case Presentation: An 84-year-old woman with a 6 cm in diameter infrarenal AAA underwent EVAR at our hospital. During the procedure, intravenous heparin was administered to keep the activated clotting time around 300 seconds. One hour after the procedure, the patient complained of pain on her right side abdomen. Physical examination revealed a tender mass in the right lower abdominal wall. Laboratory studies showed a fall in hemoglobin from 12.7 g/dl to 9.3 g/dl. Ultrasound (US) examination demonstrated an 8 × 5 cm hematoma within the right rectus muscle. Follow-up US examination revealed that the hematoma had enlarged and a computed tomography (CT) examination of the lower abdomen was performed. CT scan showed a smooth-shaped mass within the layers of the anterolateral abdominal wall leading to enlargement of the right rectus abdominis muscle without signs of active bleeding. A conservative management was considered. Result: The clinical course was uneventful with a stable hemodynamic state. The patient was discharged 12 days later and was doing well at the 2 week follow-up. Conclusion: Spontaneous rectus sheath hematoma is an unusual complication of a patient on anticoagulant therapy during EVAR. A prompt radiological investigation may prevent unnecessary surgical procedures in this unusual complication. PMID:23555371

    Objective A subdural drain using urokinase after a burr hole hematoma evacuation was performed for subacute subdural hematoma (SASDH), and its effectiveness and safety in elderly patients were evaluated. Methods Between January 2013 and May 2015, subdural drains using urokinase after burr hole hematoma evacuation were performed in 19 elderly patients. The inclusion criteria were as follows: 1) a subdural hematoma occurring between 4 and 20 days after injury; 2) worsening neurological symptoms, from mild to moderate or severe, due to injury during the subacute stage; 3) a mix of solid clots (high-density lighter shadow) and fluid hematoma (low-density darker shadow) on the computed tomography (CT) scan; 4) a score of ≥9 on the Glasgow Coma Scale (GCS) assessed immediately before surgery; and 5) an age of ≥65 years. When the majority of the hematoma was evacuated on the CT, we removed the catheter. Results Under local anesthesia, a catheter was inserted into the hematoma through a burr hole. The mean age of the patients was 73.7 years (range, 65-87 years). The mean preoperative GCS score was 11.2 (range, 10-13), and the mean Glasgow Outcome Scale score for all patients was 5 at discharge. No recurrences of hematomas or surgical complications were observed. Conclusion A subdural drain using urokinase after burr hole hematoma evacuation under local anesthesia is thought to be an effective and safe method of blood clot removal with low morbidity. This surgical method is less invasive for treating elderly patients with SASDH. PMID:27857916

    The present study is a continuation of an earlier article published on the incidence, clinical manifestations, treatment and risk factors associated with postlithotripsy renal hematomas (1). To assess the possible influence of the size and radiodensity of kidney stones on the incidence and clinical behavior of renal postlithotripsy hematomas. Observational prospective study of 324 renal units in the same number of patients undergoing extracorporeal renal lithotripsy. The variables "calculus size" and "radiographic calculus density" were evaluaArch. ted statistically by means of the IPSS 0.15 program on the basis of 42 postlithotripsy hematomas diagnosed and grouped according to their clinical behavior. Higher incidence of hematomas was observed in hiperdense calculi (25%) versus medium density calculi (7,4%), this difference was significant in the asymptomatic hematoma group. Calculus size was unrelated to the incidence of renal hematoma, but there was a significant association between renal hematoma and radiographic calculus density, probably due to the relation of radiographic density to chemical composition and, ultimately, to hardness and ultrastructure. Ultrastructure is yet another factor, among others, to be taken into account as a potential conditioning factor for this complication.

    2018-05-02

    A 28-year-old healthy man was admitted to our hospital because of right-sided headache, vomiting, and lower back pain after the administration of vardenafil. Computed tomography and magnetic resonance imaging of the brain showed a small, right-sided, subdural hematoma. A lumbar magnetic resonance imaging showed a longitudinally extended subdural hematoma. He had no history of trauma. We speculated that vardenafil might have had an association with the bleeding. Several reports have suggested a relationship between phosphodiesterase-5 inhibitors and intracerebral or subarachnoid hemorrhage. Our case suggested that there may also be risks of bleeding into the subdural space. Although headache and nausea are common side effects of vardenafil, hemorrhagic diseases should also be considered when symptoms are severe or prolonged. Copyright © 2018 National Stroke Association.

    To detect predictors of the clinical course and outcome of cerebellar hematoma in conscious patients that may help in decision making. This study entails retrospective and prospective review and collection of the demographic, clinical, and radiologic data of 92 patients with cerebellar hematoma presented conscious and initially treated conservatively. Primary outcome was deterioration lower than a Glasgow Coma Scale score of 14 and secondary outcome was Glasgow Outcome Scale score at discharge and 3 months later. Relevant data to primary outcome were used to create a prediction model and derive a risk score. The model was validated using a bootstrap technique and performance measures of the score were presented. Surgical interventions and secondary outcomes were correlated to the score to explore its use in future decision making. Demographic and clinical data showed no relevance to outcome. The relevant initial computed tomography criteria were used to build up the prediction model. A score was derived after the model proved to be valid using internal validation with bootstrapping technique. The score (0-6) had a cutoff value of ≥2, with sensitivity of 93.3% and specificity of 88.0%. It was found to have a significant negative association with the onset of neurologic deterioration, end point Glasgow Coma Scale scores and the Glasgow Outcome Scale scores at discharge. The score was positively correlated to the aggressiveness of surgical interventions and the length of hospital stay. Early definitive management is critical in conscious patients with cerebellar hematomas and can improve outcome. Our proposed score is a simple tool with high discrimination power that may help in timely decision making in those patients. Copyright © 2017 Elsevier Inc. All rights reserved.

Retrospective analysis of the characteristics and outcomes of the spontaneous rectus sheath hematomas diagnosed over the last 12years was conducted. 24 patients were included (66% women; mean age: 74years; range: 54-87). All cases presented predisposing factors mainly anticoagulant therapy in 21 (87.5%) patients, hypertension in 19 (79.1%) and abdominal surgery in 12 (50%) cases. Eighteen (75%) referred triggering factors like coughing being the most common one, present in 17 (70.8%) patients. The main clinical findings were abdominal pain in 21 (87.5%) cases and the existence of an abdominal mass in 20 (83.3%). The diagnosis was confirmed by abdominal ultrasonography and/or computerized tomography in 23 (95.8%) patients. Nineteen cases (79.1%) responded to conservative management while 5 (20.8%) required interventional treatment, which consisted in an arteriography with selective embolization of the epigastric arteries in all cases. Four (80%) of the patients needing interventional treatment were receiving low molecular weight heparin. Nine (37.5%) patients developed hypovolemic shock and 1 (4%) died. Spontaneous rectus sheath hematomas should be considered in the differential diagnosis of abdominal pain, particularly in elderly women under anticoagulant therapy with onset of symptoms after a bout of cough. Most cases respond to conservative management, although those related to low molecular weight heparin might require interventional treatment; arteriography with selective embolization of the epigastric arteries is the first therapeutic option.

    Whiplash Associated Disorders (WAD) has been reported as an adult phenomenon. Whiplash injury has classically been described as a cervical soft tissue hyperextension- flexion injury after a trauma such as a rear end impact car crash, contact sport injuries, blows to the head from a falling object or a punch and shaken baby syndrome and is mostly seen in adults . It is important as it may cause severe disability due to spinal cord injury, decrease work productivity and even retropharyngeal hematoma resulting airway obstruction and mortality due to bleeding amongst deep cervical fascias. We describe a case of retropharyngeal hematoma after whiplash injury in a childhood.

    An 88-year-old female presented with a left thigh pain and dysuria. She visited our hospital 2 week after she noticed her symptoms. She stated that she might have a low-energy fall, but she could not identify the exact onset. Her radiograph of the pelvis (Figure 1) showed displaced left pubic ramus fracture. Her computed tomographic scanning of the pelvis (Figure 2) showed massive intrapelvic hematoma (axial size, 11 cm by 5 cm) around the fracture site, although she did not use any anticoagulants. Because her bone mineral density was 0.357 g/cm{sup 2}, and T score was -4.8 SD, she startedmore » a bisphosphonate therapy. She received a bed-rest physical therapy for 6 weeks, and the hematoma regressed spontaneously. She started full weight bearing after 6 weeks, and walked by a walker after 8 weeks. Although it is extremely rare to develop massive chronic intra-pelvic hematoma after a lowenergy pubic ramus fracture without any use of anticoagulants, it may occur in elderly and severely osteoporotic patient.« less

    A healthy 26-year-old man visited the Emergency Department due to right lower quadrant pain of 2 days' duration that developed after wakeboarding. There was no history of direct trauma to the abdomen. Physical examination revealed tenderness and rebound tenderness on the right lower quadrant area. There was no palpable abdominal mass. Computed tomography (CT) of the abdomen was undertaken to discern the causes of acute abdomen, including acute appendicitis. CT revealed a small-size rectus sheath hematoma beneath the lower end of the right rectus muscle. The patient was admitted for supportive care including pain control and was discharged with improvement after 5 days. Rectus sheath hematoma can be caused by not only a direct blow but also non-contact strenuous exercise, for example, wakeboarding in this case. Although the majority of rectus sheath hematomas are self-limiting, some can cause peritoneal irritation signs, mimicking acute abdomen, and eventually lead to unnecessary laparotomy without clinical suspicion and ancillary tests including CT scan and ultrasonography.

  1. Developing a model of chronic subdural hematoma.

    PubMed

    2011-01-01

    Chronic subdural hematoma (CSDH) is a common neurosurgical condition that has a high incidence in the increasing elderly population of many countries. Pathologically, it is defined as a persistent liquefied hematoma in the subdural space more than 3 weeks old that is generally encased by a membraneous capsule. CSDHs likely originate after minor head trauma, with a key factor in its development being the potential for a subdural cavity to permit its expansion within, which is usually due to craniocerebral disproportion. The pathogenesis of CSDH has been attributed to osmotic or oncotic pressure differences, although measurements of these factors in the CSDH fluid do not support this theory. Current belief is that CSDH arises from recurrent bleeding in the subdural space, caused by a cycle of local angiogenesis, inflammation, coagulation and ongoing fibrinolysis. However, because of a lack of detailed knowledge about the precise mechanisms, treatment is often limited to surgical interventions that are invasive and often prone to recurrence. Thus, it is possible that an easily reproducible and representative animal model of CSDH would facilitate research in the pathogenesis of CSDH and aid with development of treatment options.

    Spontaneous nongastrointestinal bleeding in patients treated with nonsteroidal anti-inflammatory drugs is an extremely rare occurrence. Herein, the case of a 60-year-old woman with severe bilateral hip osteoarthritis treated with diclofenac sodium, who presented with manifestations of a spontaneous hematoma of the right thigh, is described. There was no history of trauma or family history of bleeding disorder. Thorough investigation excluded a hemorrhagic disorder. The patient was treated conservatively with success and was advised to discontinue diclofenac.

    A 72-year-old patient was admitted to the medical intensive care unit due to a right-sided, hospital-acquired pneumonia and septic shock with respiratory failure and deterioration of chronic renal failure. During hospitalization the patient required hemodynamic support with norepinephrine and dobutamine, mechanical ventilation and hemodialysis. The patient suffered a non-ST segment elevation myocardial infarction (NSTEMI) and received dual antiplatelet therapy. After 14 days an acute intrapulmonary infiltrate of unknown origin developed, accompanied by fever and a significant increase of the C‑reactive protein (CRP) level. Chest radiography and a computed tomography (CT) scan showed a well-defined, round, high-attenuation lesion in the lungs and a suspected infected pulmonary hematoma, which was confirmed by percutaneous aspiration biopsy. There was no evidence of trauma and it is believed that the hematoma occurred spontaneously, probably because of the dual antiplatelet therapy. Double antibiotic treatment was started but no surgery was performed after consultation with a thoracic surgeon. The antiplatelet drugs were temporarily withdrawn until the size of the hematoma showed no further increase and then antiplatelet therapy was continued. After stabilization the patient was discharged from hospital and 6 months later a follow-up chest X‑ray showed almost complete resolution of the hematoma.

    Burr-hole drainage of chronic subdural hematomas are routine operative procedures done by neurosurgical residents. Common postoperative complications include acute epidural and/or subdural bleeding, tension pneumocephalus, intracranial hematomas and ischemic cerebral infarction. We report an interesting post-operative complication of a 'subarachnoid cyst' after burr-hole evacuation of a chronic subdural hematoma. The authors hypothesize that the 'cyst' is likely secondary to the splitting of the adjacent neomembrane within its arachnoid-brain interface by iatrogenic irrigation of the subdural space. Over time, this 'cyst' develops into an area of gliosis which eventually causes long-term scar epilepsy in the patient. As far as we are aware, this is the first complication of such a 'subarachnoid cyst' post burr-hole drainage reported in the literature.

    The objective is to know the prevalence of renal hematoma after lithotripsy in our unit, as well as the incidence of symptomatic and/or progressive hematomas, their clinical behavior and management, and also the factors potentially influencing those features. A prospective study in which we analyzed various parameters from the database on 314 patients undergoing SWL on 324 renal units. SPSS 15.01 was employed for statistical analysis under supervision of biostatistics experts. The diagnosis of hematoma was obtained with clinical data (history and physical examination), blood analysis, and ultrasound, this latter with the complement of CT scan in isolated cases. All patients underwent follow-up by means of phone contacts over a period between 7-19 months after lithotripsy. The prevalence of hematoma was 13% but only 6.2% were symptomatic. Accumulated incidence of hematoma with progressive evolution was 2.16%, and blood transfusion requirement due to hematoma was 0.92% of all lithotripsies, which represents 7.14% or them. Factors statistically associated with the incidence of hematoma were: number of shock waves (over 2300), total energy (above 150J), number of KV (above 17.5), preoperative microhematuria, perioperative hypertension, cystine lithiasis, hydrocalyx, caliceal localizations (mainly lower calyces), the association of coronary artery disease with hypertension, or hepatic diseases, chronic hepatopathy, elevation of transaminases, usual intake of anti platelet aggregation drugs and nonsteroidal anti-inflammatory drugs (mainly with prior low-weight heparin treatment for hematoma progression), and a combination of the previous with preoperative hypertension (for symptomatic hematoma), as well as the presence of multiple stones treated in the some session, with different degrees of association for the various subgroups of hematomas. We observed differences in clinical behavior depending on the type of hematoma (subcapsular and perirenal) and 12% of the patients

    Patients with glutaric aciduria type 1 (GA1), a rare inherited metabolic disorder, have an increased risk for subdural hematomas (SDHs). GA1 is therefore generally included in the differential diagnosis of children presenting with SDHs. This retrospective cohort study reviews all 25 registered, in the Dutch Diagnosis Registration for Metabolic Disorders, GA1 patients in the Netherlands. This was done between May 2014 and November 2014 to determine the lifetime incidence of SDHs in this population. Seventeen patients were diagnosed either due to clinical symptoms or because of family members with GA1. One out of these 17 had a SDH. This patient showed widened Sylvian fissures on MRI, characteristic for GA1. Eight patients were diagnosed by newborn screening. Three of them had neuroimaging results, and none of them had SDHs. This study shows an overall lower incidence (4.0 %) of SDHs in patients with GA1 than reported in the literature (20-30 %). This finding, in combination with the fact that SDHs in GA1 appear to occur only in the presence of characteristic brain abnormalities on imaging, we recommend that GA1 should not routinely be a part of the differential diagnosis of children with unexplained SDHs in the absence of imaging characteristics suggestive of GA1. • Glutaric aciduria type 1 is a rare metabolic disorder predisposing children to subdural hematoma development due to brain abnormalities. • Because of these subdural hematomas, glutaric aciduria type 1 testing is part of abusive head trauma work-up. What is new: • The overall subdural hematoma incidence in glutaric aciduria type 1 patients is much lower than previously reported and only occurs in case of predisposing brain abnormalities.

  8. Chronic Subdural Hematoma in the Aged, Trauma or Degeneration?

    PubMed

    2016-01-01

    Chronic subdural hematomas (CSHs) are generally regarded to be a traumatic lesion. It was regarded as a stroke in 17th century, an inflammatory disease in 19th century. From 20th century, it became a traumatic lesion. CSH frequently occur after a trauma, however, it cannot occur when there is no enough subdural space even after a severe head injury. CSH may occur without trauma, when there is sufficient subdural space. The author tried to investigate trends in the causation of CSH. By a review of literature, the author suggested a different view on the causation of CSH. CSH usually originated from either a subdural hygroma or an acute subdural hematoma. Development of CSH starts from the separation of the dural border cell (DBC) layer, which induces proliferation of DBCs with production of neomembrane. Capillaries will follow along the neomembrane. Hemorrhage would occur into the subdural fluid either by tearing of bridge veins or repeated microhemorrhage from the neomembrane. That is the mechanism of hematoma enlargement. Trauma or bleeding tendency may precipitate development of CSH, however, it cannot lead CSH, if there is no sufficient subdural space. The key determinant for development of CSH is a sufficient subdural space, in other words, brain atrophy. The most common and universal cause of brain atrophy is the aging. Modifying Virchow's description, CSH is sometimes traumatic, but most often caused by degeneration of the brain. Now, it is reasonable that degeneration of brain might play pivotal role in development of CSH in the aged persons.

    Perioperative management of patients on anticoagulant therapy prior to interventional pain procedures creates a challenge when balancing the risk of bleeding against thromboembolic events. We report a case of epidural hematoma formation in the cervical spine following interlaminar epidural steroid injection in an elderly woman with chronic neck and arm pain, who was on clopidogrel therapy. This is the first reported case of hematoma formation immediately following an epidural steroid injection possibly associated with clopidogrel, even though established guidelines on the timing of the discontinuation of clopidogrel prior to the procedure were exceeded. Severe pain appears to be the first symptom of hematoma formation, and therefore immediate diagnostic workup and evacuation of hematoma are essential in preventing neurological damage. It may be advisable to carry out a test specific for clopidogrel such as the P2Y12 to ensure that there is no residual action on platelet aggregation function, particularly in patients who may be slow metabolizers of clopidogrel. Caution is advised prior to administering analgesics with antiplatelet effects such as ketorolac.

    The BRUISE CONTROL trial (Bridge or Continue Coumadin for Device Surgery Randomized Controlled Trial) demonstrated that a strategy of continued warfarin during cardiac implantable electronic device surgery was safe and reduced the incidence of clinically significant pocket hematoma (CSH). CSH was defined as a post-procedure hematoma requiring further surgery and/or resulting in prolongation of hospitalization of at least 24 h, and/or requiring interruption of anticoagulation. Previous studies have inconsistently associated hematoma with the subsequent development of device infection; reasons include the retrospective nature of many studies, lack of endpoint adjudication, and differing subjective definitions of hematoma. The BRUISE CONTROL INFECTION (Bridge or Continue Coumadin for Device Surgery Randomized Controlled Trial Extended Follow-Up for Infection) prospectively examined the association between CSH and subsequent device infection. The study included 659 patients with a primary outcome of device-related infection requiring hospitalization, defined as 1 or more of the following: pocket infection; endocarditis; and bloodstream infection. Outcomes were verified by a blinded adjudication committee. Multivariable analysis was performed to identify predictors of infection. The overall 1-year device-related infection rate was 2.4% (16 of 659). Infection occurred in 11% of patients (7 of 66) with previous CSH and in 1.5% (9 of 593) without CSH. CSH was the only independent predictor and was associated with a >7-fold increased risk of infection (hazard ratio: 7.7; 95% confidence interval: 2.9 to 20.5; p < 0.0001). Empiric antibiotics upon development of hematoma did not reduce long-term infection risk. CSH is associated with a significantly increased risk of infection requiring hospitalization within 1 year following cardiac implantable electronic device surgery. Strategies aimed at reducing hematomas may decrease the long-term risk of infection. (Bridge or Continue

    A rare case of acute epidural hematoma of the posterior fossa caused by forehead impact is reported. This 36-year-old man fell from a truck and hit his face. He was conscious and was brought to our center 30 minutes after the injury. On admission, a contused wound of the right forehead was noticed. He was restless and had severe pain in the neck and upper extremities. Skull X-ray showed a linear fracture of the frontal bone and computed tomography (CT) scan was normal. He continued to be restless and sudden respiratory arrest and pupillary dilation occurred 10 hours after the admission. A CT scan revealed a lenticular high density area in the left posterior fossa which extended to the supratentorial region. The 4th ventricle was compressed and displaced to the right and also the quadrigeminal and ambient cisterns were not visualized at all. Immediate surgery disclosed a 30 g epidural hematoma of the left posterior fossa and the supratentorium and the clot was completely evacuated. The source of bleeding could not be identified. Opening of the dura revealed contusion in the occipital lobe. He died on the 17th postoperative day. The possible mechanism in the production of the posterior fossa hematoma in this case is discussed.

  13. The hematoma block: a simple, effective technique for closed reduction of ankle fracture dislocations.

    2011-01-01

    Management of a dislocated ankle fracture can be challenging because of instability of the ankle mortise, a compromised soft tissue envelope, and the potential neurovascular compromise. Every effort should be made to quickly and efficiently relocate the disrupted ankle joint. Within the emergency department setting, narcotics and benzodiazepines can be used to sedate the patient before attempting closed reduction. The combination of narcotics and benzodiazepines provides relief of pain and muscle guarding; however, it conveys a risk of seizure as well as respiratory arrest. An alternative to conscious sedation is the hematoma block, or an intra-articular local anesthetic injection in the ankle joint and the associated fracture hematoma. The hematoma block offers a comparable amount of analgesia to conscious sedation without the additional cardiovascular risk, hospital cost, and procedure time.

    BACKGROUND Hematoma expansion is associated with poor outcome in intracerebral hemorrhage (ICH) patients. The spot sign and the blend sign are reliable tools for predicting hematoma expansion in ICH patients. The aim of this study was to compare the accuracy of the two signs in the prediction of hematoma expansion. MATERIAL AND METHODS Patients with spontaneous ICH were screened for the presence of the computed tomography angiography (CTA) spot sign and the non-contrast CT (NCCT) blend sign within 6 hours after onset of symptoms. The sensitivity, specificity, and positive and negative predictive values of the spot sign and the blend sign in predicting hematoma expansion were calculated. The accuracy of the spot sign and the blend sign in predicting hematoma expansion was analyzed by receiver-operator analysis. RESULTS A total of 115 patients were enrolled in this study. The spot sign was observed in 25 (21.74%) patients, whereas the blend sign was observed in 22 (19.13%) patients. Of the 28 patients with hematoma expansion, the CTA spot sign was found on admission CT scans in 16 (57.14%) and the NCCT blend sign in 12 (42.86%), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of the spot sign for predicting hematoma expansion were 57.14%, 89.66%, 64.00%, and 86.67%, respectively. In contrast, the sensitivity, specificity, positive predictive value, and negative predictive value of the blend sign were 42.86%, 88.51%, 54.55%, and 82.80%, respectively. The area under the curve (AUC) of the spot sign was 0.734, which was higher than that of the blend sign (0.657). CONCLUSIONS Both the spot sign and the blend sign seemed to be good predictors for hematoma expansion, and the spot sign appeared to have better predictive accuracy.

    Solid or nodular enhancement is typical of soft tissue sarcomas although high grade soft tissue sarcomas and those with internal hemorrhage often appear heterogeneous with areas of nonenhancement and solid or nodular enhancement. These MRI findings often prompt an orthopedic oncology referral, a biopsy or surgery. However, not all masses with these imaging findings are malignant. We report the multimodality imaging findings of two surgically proven chronic expanding hematomas (CEH) with imaging features that mimicked sarcomas. A third case of nonenhancing CEH of the lower extremity is also presented as a comparison. It is important that in the correct clinical scenario with typical imaging findings, the differential diagnosis of a chronic expanding hematoma be included in the workup of these patients. An image-guided biopsy of nodular tissue within such masses that proves to be negative for malignancy should not necessarily be considered discordant. A correct diagnosis may prevent a morbid unnecessary surgery and may indicate the need for a conservative noninvasive follow-up with imaging.

    Acute subdural hematoma (ASDH) is mostly caused by head trauma, but intrinsic causes also exist such as aneurysm rupture. We describe here a case involving a man in his 70s who was found lying on the bedroom floor by his family. CT performed at the hospital showed ASDH and a forensic autopsy was requested. Postmortem cerebral angiography showed dilatation of the bifurcation of the middle cerebral artery, which coincided with the dilated part of the Sylvian fissure. Extravasation of contrast medium into the subdural hematoma from this site was suggestive of a ruptured aneurysm. Autopsy revealed a fleshy hematoma (total weight 110 g) in the right subdural space and findings of brain herniation. As indicated on angiography, a ruptured saccular aneurysm was confirmed at the bifurcation of the middle cerebral artery. Obvious injuries to the head or face could not be detected on either external or internal examination, and intrinsic ASDH due to a ruptured middle cerebral artery aneurysm was determined as the cause of death. One of the key points of forensic diagnosis is the strict differentiation between intrinsic and extrinsic onset for conditions leading to death. Although most subdural hematomas (SDH) are caused by extrinsic factors, forensic pathologists should consider the possibility of intrinsic SDH. In addition, postmortem angiography can be useful for identifying vascular lesions in such cases.

    We reported a case of spontaneous retroperitoneal hematoma (SRH) simulating a ruptured infrarenal aortic aneurysm. A 72-year-old man with a history of infrarenal aortic aneurysm and end-stage renal disease on hemodialysis presented with malaise and nonspecific central abdominal pain and left loin discomfort. An emergency computed tomography scan showed a large retroperitoneal hematoma and clinical suspicion of ruptured infrarenal aortic aneurysm. However, the hematoma was discontinuous with the aneurysm sac and raised the clinical suspicion on dual pathology. The SRH was treated conservatively with transfusion of blood products, and the aneurysm was treated with nonemergency endovascular repair electively. This case demonstrates the importance of recognizing different clinical and radiological characteristics and be aware of dual pathology. PMID:28031651

A total of 366 consecutive patients with ASDH treated between January 2006 and September 2012 were identified in our hospital database. Patients with ASDH clot thickness >10mm in the frontoparietotemporal region and showing a midline shift >10mm on the initial computed tomography (CT) scan were divided into two groups according to subsequent spontaneous resolution. Univariate and multivariate logistic regression analyses were used to identify factors predictive of rapid spontaneous ASDH resolution. Fifty-six ASDH patients met study criteria and 18 demonstrated rapid spontaneous resolution (32%). Majority of these patients were not operated because of poor prognosis/condition and in accordance to family wishes. Univariate analysis revealed significant differences in use of antiplatelet agents before head injury and in the incidence of a low-density band between the hematoma and inner wall of the skull bone on the initial CT. Use of antiplatelet agents before head injury (OR 19.6, 95% CI 1.5-260.1, p=0.02) and the low-density band on CT images (OR 40.3, 95% CI 3.1-520.2, p=0.005) were identified as independent predictive factors by multivariate analysis. Our analysis suggested that use of antiplatelet agents before head injury and a low-density band between the hematoma and inner skull bone on CT images (indicative of cerebrospinal fluid infusion into the subdural space) increase the probability of rapid spontaneous resolution.

    A 69-year-old man developed motor aphasia and right hemiparesis with severe headache, during the treatment of cellulitis and sepsis due to cat bites. Brain CT showed a low density, crescent-shaped lesion in the left subdural space, which was hypointense on brain diffusion-weighted imaging (DWI). One week later, when his neurological symptoms had worsened, the signal of the subdural lesion had changed to hyperintense on DWI. The lesion was capsule-shaped when enhanced by Gadolinium. The signal changes on DWI of the lesion indicated the existing hematoma had changed to an empyema, or so-called infected subdural hematoma, due to a hematogenous bacterial infection. Pasteurella multocida, a resident microbe in the oral cavity of cats, could be the responsible pathogen in this case. The patient recovered completely after treatment with intravenous high dose antibiotics. This is an important case report describing the transformation from a chronic subdural hematoma into a subdural empyema by DWI.

    Context We present a rare and interesting case of hemorrhagic lumbar facet cysts accompanying a spinal subdural hematoma at the same level suggesting a possible mechanism by which spinal subdural hematomas can arise. Findings A 71-year-old man presented with persistent sciatic pain and intermittent claudication. Magnetic resonance imaging demonstrated a multilocular mass lesion that showed high signal intensity in both T1- and T2-weighted images, and was located both inside and outside of the spinal canal. Computed tomographic myelography showed a cap-shaped block of the dural tube at L5 and computed tomography with L5–S facet arthrography demonstrated cystic masses. The patient was diagnosed with lumbar radiculopathy caused by hemorrhagic facet cysts, and then progressed to surgical treatment. Surgery revealed that the cysts contained blood clots, and intraoperative findings that the inside of the dural tube appeared blackish and that the dural tube was tensely ballooned after removal of the cysts led us to explorative durotomy. The durotomy demonstrated concentrated old blood pooling both in the dorsal and ventral subdural space, and these spaces were subsequently drained. After surgery, his sciatic pain and intermittent claudication resolved. There was no evidence of cyst mass recurrence at 2 years of follow-up. Conclusion We propose a newly described mechanism for the formation of spinal subdural hematomas. We recommend surgeons be alert to epidural lesions causing repeated acute compression of the dural tube, which can cause spinal subdural hematoma, and consider the possible coexistence of these lesions in diagnosis and strategic surgical decisions.

    Interventricular septal hematoma is a rare complication of retrograde chronic total occlusion (CTO) percutaneous coronary interventions (PCI) with a typically benign course. Here we report two cases of interventricular septal hematoma and coronary-cameral fistula development after right coronary artery (RCA) CTO-PCI using a retrograde approach. Both were complicated by development of ST-segment elevation and chest pain. One case was managed actively and the other conservatively, both with a favorable outcome. PMID:27668097

  4. Vascular Endothelial Growth Factor Concentration in Chronic Subdural Hematoma Fluid Is Related to Computed Tomography Appearance and Exudation Rate

    Abstract Chronic subdural hematoma (CSH) is characterized by a net increase of volume over time. Major underlying mechanisms appear to be hemorrhagic episodes and a continuous exudation, which may be studied using labeled proteins to yield an exudation rate in a given patient. We tested the hypothesis that the concentration of vascular endothelial growth factor (VEGF) in hematoma fluid correlates with the rate of exudation. Concentration of VEGF was determined in 51 consecutive patients with CSH by the sandwich immune enzyme-linked immunosorbent assay technique. Mean values were correlated with exudation rates taken from the literature according to the appearance of CSH on computed tomography (CT) images. The CT appearance of each CSH was classified as hypodense, isodense, hyperdense, or mixed density. Mean VEGF concentration was highest in mixed-density hematomas (22,403±4173 pg/mL; mean±standard error of the mean; n=27), followed by isodense (9715±1287 pg/mL; n=9) and hypodense (5955±610 pg/mL; n=18) hematomas. Only 1 patient with hyperdense hematoma fulfilled the inclusion criteria, and the concentration of VEGF found in this patient was 24,200 pg/mL. There was a statistically significant correlation between VEGF concentrations and exudation rates in the four classes of CT appearance (r=0.98). The current report is the first to suggest a pathophysiological link between the VEGF concentration and the exudation rate underlying the steady increase of hematoma volume and CT appearance.With this finding, the current report adds another piece of evidence in favor of the pathophysiological role of VEGF in the development of CSH, including mechanisms contributing to hematoma growth and CT appearance.

    Abstract Chronic subdural hematoma (CSDH) is an inflammatory and angiogenic disease. Vascular endothelial growth factor (VEGF) has an important effect on the pathological progression of CSDH. The matrix metalloproteinases (MMPs) and VEGF also play a significant role in pathological angiogenesis. Our research was to investigate the level of MMPs and VEGF in serum and hematoma fluid. Magnetic Resonance Imaging (MRI) shows the characteristics of different stages of CSDH. We also analyzed the relationship between the level of VEGF in subdural hematoma fluid and the appearances of the patients' MRI. We performed a study comparing serum and hematoma fluid in 37 consecutive patients with primary CSDHs using enzyme-linked immunosorbent assay (ELISA). MMP-2 and MMP-9 activity was assayed by the gelatin zymography method. The patients were divided into five groups according to the appearance of the hematomas on MRI: group 1 (T1-weighted low, T2-weighted low, n=4), group 2 (T1-weighted high, T2-weighted low, n=11), group 3 (T1-weighted mixed, T2-weighted mixed, n=9), group 4 (T1-weighted high, T2-weighted high, n=5), and group 5 (T1-weighted low, T2-weighted high, n=8). Neurological status was assessed by Markwalder score on admission and at follow-up. The mean age, sex, and Markwalder score were not significantly different among groups. The mean concentration of VEGF, MMP-2, and MMP-9 were significantly higher in hematoma fluid than in serum (p<0.01). The level of pro-MMP-2 was higher in hematoma fluid (p<0.01). Measurement of MMP-9 showed both pro and active forms in both groups, but levels were higher in hematoma fluid (p<0.01 and p<0.01, respectively). Mean VEGF concentration was highest in group 1 (21,979.3±1387.3 pg/mL), followed by group 2 (20,060.1±1677.2 pg/mL), group 3 (13,746.5±3529.7 pg/mL), group 4 (7523.2±764.9 pg/mL), and lowest in group 5 (6801.9±618.7 pg/mL). There was a significant correlation between VEGF concentrations and MRI type (r=0

    The present study aimed to clarify the relationship between frailty and prognosis of patients with chronic subdural hematoma. This retrospective study involved 211 patients aged ≥65 years with chronic subdural hematoma, who underwent surgery at Higashihiroshima Medical Center, Hiroshima, Japan, between July 2011 and May 2017. The study outcome was the patient's modified Rankin Scale score at 3 months after surgery. A logistic regression analysis was carried out to analyze factors that influenced the outcome. Chronic subdural hematoma patients with frailty had a poorer prognosis than those without (median modified Rankin Scale: 4 and 2, P < 0.001; proportions of patients discharged to home: 35% and 91%, P < 0.001, respectively). After adjusting for patients' background, the patients' modified Rankin Scale scores at 3 months after surgery were found to be associated with age, controlling nutritional status score and recurrence, but not with frailty. However, receiver operating characteristic curves of the model with the Clinical Frailty Scale were more accurately correlated with prognosis than those of the model without this scale (area under the curve 0.98, 95% confidence interval 0.96-0.99; and 0.87, 95% confidence interval 0.82-0.91, respectively.) CONCLUSIONS: Chronic subdural hematoma patients with frailty had poorer prognosis than those without. The evaluation of the presence of frailty on admission can be an important factor in the prediction of the prognosis of chronic subdural hematoma patients.

    Spontaneous retroperitoneal hematoma (SRH) is a potentially fatal clinical entity requiring immediate recognition and intervention. The clinical records of 18-year-old and older patients admitted to the University Hospital Marqués de Valdecilla from 2003 to 2013 were reviewed. "Spontaneous" was defined as unrelated to trauma, invasive procedures or bleeding due to aortic aneurysm rupture. Thirty-four patients with SRH (44% were on anticoagulant drugs). One-third of cases had chronic renal insufficiency. Abdominal pain was the most common symptom both in anticoagulated and non-anticoagulated patients (80% in anticoagulated and 89% in non-anticoagulated patients). About one half of the patients developed shock. A CT scan was the most commonly performed diagnostic test, followed by abdominal ultrasound. Most cases were managed conservatively (80%). More than half of the patients (66%) restarted anticoagulation therapy after the acute event with a mean delay of 19 days (range 2-90 days). None of them suffered a new bleeding episode. Restarting the anticoagulation treatment after hematoma resolution seems to be a safe practice. There is an increasing frequency of SRH in non-anticoagulated patients.

    Burr-hole drainage of chronic subdural hematomas are routine operative procedures done by neurosurgical residents. Common postoperative complications include acute epidural and/or subdural bleeding, tension pneumocephalus, intracranial hematomas and ischemic cerebral infarction. We report an interesting post-operative complication of a ‘subarachnoid cyst’ after burr-hole evacuation of a chronic subdural hematoma. The authors hypothesize that the ‘cyst’ is likely secondary to the splitting of the adjacent neomembrane within its arachnoid-brain interface by iatrogenic irrigation of the subdural space. Over time, this ‘cyst’ develops into an area of gliosis which eventually causes long-term scar epilepsy in the patient. As far as we are aware, this is the first complication of such a ‘subarachnoid cyst’ post burr-hole drainage reported in the literature. PMID:27366276

    Near-Infrared Spectroscopy (NIRS) is an emerging medical countermeasure for rapid, field detection of hematomas caused by traumatic brain injury (TBI). Bench and animal tests to determine NIRS sensitivity and specificity are needed. However, current animal models involving non-invasively induced, localized neural damage are limited. We investigated an in vivo murine hematoma model in which cerebral hemorrhage was induced noninvasively by high-intensity focused ultrasound (HIFU) with calibrated positioning and parameters. To characterize the morphology of induced hematomas, we used skull-intact histological evaluation. A multi-wavelength fiber-optic NIRS system with three source-detector separation distances was used to detect hematoma A 1.1 MHz transducer produced consistent small-to-medium hematoma localized to a single hemisphere, along with bruising of the scalp, with a low mortality rate. A 220 kHz transducer produced larger, more diffuse hematomas, with higher variability in size and a correspondingly higher mortality rate. No skin bruising or blood accumulation between the skin and skull was observed following injury application with the 220 kHz transducer. Histological analysis showed higher sensitivity for larger hematomas (>4x4 mm2). NIRS optical density change after HIFU was able to detect all hematomas, with sensitivity dependent on wavelength and separation distance. While improvements in methods for validating cerebral blood distribution are needed, the HIFU hematoma model provided useful insights that will inform development of biologically relevant, performance test methods for cerebral NIRS systems.

    Sinonasal organized hematoma is a rare, benign disease that can be locally aggressive and may be mistaken for malignancy. Because of its rarity, the clinical characteristics are not well known. The aim of this study is to investigate the distinguishing features of organized hematoma with an emphasis on incidence change. In this retrospective study, we reviewed the records of 23 patients with organized hematoma confirmed histopathologically among 5,378 patients who underwent endoscopic sinus surgery performed by a single surgeon from January 1995 to December 2014 at a tertiary care center. Clinical symptoms, endoscopic photography, computed tomography, and operative findings were reviewed. We also reviewed the relevant literature. Age, sex, site, origin subsite and histopathology were investigated. A statistical review was performed using R 3.1.2 to examine incidence change. The most common complaint was frequent epistaxis and nasal obstruction (52.1%). Of the 23 patients, eight were women and 15 were men with an age range of 18 to 75 years. (mean 38.9 years). Nine of these hematomas occurred on the right side and 14 on the left side. The predominant occurrence site was the antrum (65%), followed by the septum (17.3%), inferior turbinate (8%), and ethmoid sinus (8%). The incidence steadily increased over 20 years. Investigation of the clinical characteristics and incidence change of organized hematoma can provide useful information. Through analysis of the 23 cases in our study, the age distribution was found to be bimodal and the incidence of organizing hematoma was observed to steadily increase. Clinicians should be aware of these characteristics to avoid misdiagnoses of malignant tumors.

    Patient: Male, 64 Final Diagnosis: Chronic subdural hematoma Symptoms: Aphasia • headache • paresis Medication: — Clinical Procedure: Burr hole evacuation • Tranexamic acid Specialty: Neurosurgery Objective: Unusual clinical course Background: Chronic subdural hematoma (CSDH) is a common neurosurgical condition that is treated using a cranial burr hole evacuation procedure, but recurrence is common. The use of anticoagulant therapy can increase the risk of developing a recurrent subdural hematoma. We present a challenging case of a patient on long-term anticoagulant therapy following previous aortic and aortic valve surgery who had CSDH with multiple recurrences and was ultimately treated with tranexamic acid as an adjunct to surgery. Case Report: A male patient in his mid-sixties presented with a headache and bilateral CSDH. Apart from a mechanical heart valve, he was otherwise healthy. A standard burr hole evacuation was performed, but the left hematoma and symptoms recurred after three months, and he presented with additional symptoms of aphasia and right-hand weakness. He had an additional three procedures followed by recurrences over a period of six weeks. Following his fifth and final surgical procedure, he was given postoperative intravenous tranexamic acid 10 mg/kg four times during the first 24 hours with dalteparin sodium 9,500 international units (IU) twice daily. His symptoms resolved, and after nine months he had no residual hematoma, and no thromboembolic complications occurred. Conclusions: This case has demonstrated that tranexamic acid can be used as an adjunctive treatment to surgery when dealing with recurring CSDH, even in patients who require concomitant anticoagulant therapy. Although clinical trials are underway to evaluate tranexamic acid as a medical treatment for CSDH, this case report may support further studies that include patients with risk factors for thromboembolic disease.

    Intracerebral hemorrhage (ICH) volume, particularly if ≥30 mL, is a major determinant of poor outcome. We used a multinational ICH data registry to study the characteristics, course, and outcomes of supratentorial hematomas with volumes <30 mL. Basic characteristics, clinical and radiological course, and 30-day outcomes of these patients were recorded. Outcomes were categorized as early neurological deterioration (END), hematoma expansion, Glasgow Outcome Scale (GOS), and in-hospital death. Poor outcome was defined as composite of in-hospital death and severe disability (GOS ≤ 3). Comparison was conducted based on hemorrhage location. Logistic regression using dichotomized outcome scales was applied to determine predictors of poor outcome. Among 375 cases of supratentorial ICH with volumes <30 mL, expansion and END rates were 19.2% and 7.5%, respectively. Hemorrhage growth was independently associated with END (odds ratio: 28.7, 95% confidence interval [CI]: 8.51-96.5; P < .0001). Expansion rates did not differ according to ICH location. Overall, 13.9% (exact binomial 95% CI: 10.5-17.8) died in the hospital and 29.1% (CI: 24.5-34.0) had severe disability at 30 days; there was a cumulative poor outcome rate of 42.9% (CI: 37.9-48.1). Age, admission Glasgow Coma Scale, intraventricular extension, and END were independently associated with poor outcome. There was no difference in poor outcome rates between lobar and deep locations (40.2% versus 43.8%, P = .56). Patients with supratentorial ICH <30 mL have high rates of poor outcome at 30 days, regardless of location. Nearly 1 in 5 hematomas <30 mL expands, leading to END or death.

    The purpose of this study was to evaluate risk factors for renal hematoma after extracorporeal shock wave lithotripsy (SWL) for kidney stones in a matched case-control analysis of a subgroup of patients recruited from a prospective randomized cohort. Between 06/2010 and 03/2013, 418 patients underwent SWL with the MODULITH ® -SLX-F2-lithotripter for kidney stones. In 39/418 patients (9 %), ultrasound at post-treatment day 1 revealed renal hematomas. For 37 of these patients, a matched group without hematoma could be selected according to the following matching criteria: age, gender, number and energy of shock waves, stone burden and localization. Risk factors for renal hematoma after SWL were compared between the two groups. The rates of diabetes, stopped anticoagulant/antiplatelet medications and arterial hypertension were not different between the two groups (p > 0.2). The skin-kidney distance was virtually the same in both groups (p = 0.5). In the hematoma group, significantly more patients had a high (>30: n = 16) as well as a low (<21.5: n = 4) BMI when compared to the control group (n = 4; n = 0; p < 0.001). Importantly, all patients with BMI <21.5 developed renal hematomas after SWL. Patients with a high (>30) or low (<21.5) BMI had a higher risk for renal damage after SWL. Therefore, alternative endoscopic treatment options should be considered in these patients.

    Most people understand spinal manipulation therapy to be a safe procedure, and in many cases treatment is provided without a diagnosis if there is musculoskeletal pain. Cervical epidural hematoma occurs in extremely rare cases after cervical manipulation therapy. This study reports a case of epidural hematoma that occurred in the anterior spinal cord after cervical massage. A 38-year-old male patient was admitted to the emergency department for sudden weakness in the lower extremity after receiving a cervical spine massage. No fracture was found using cervical radiographs, and there were no particular findings on performing brain computed tomography or diffusion magnetic resonance imaging. However, using cervical magnetic resonance imaging, an acute epidural hematoma was observed in the anterior spinal cord from the C6 and C7 vertebrae to the T1 vertebra, compressing the spinal cord. There were no fractures or ligament injury. No surgical treatment was required as the patient showed spontaneous improvements in muscle strength and was discharged after just 1 week, following observation of the improvement in his symptoms. Although cervical epidural hematoma after cervical manipulation therapy is extremely rare, if suspected, a thorough examination must be performed in order to reduce the chances of serious neurologic sequelae.

    The potential complications of the subdural electrode implantation providing identification of the seizure focus and direct stimulation of the cerebral cortex for defining the eloquent cortical areas are epidural and subdural hematoma, cortical contusions, infection, brain edema, raised intracranial pressure, CSF leakage, and venous infarction have been previously reported in the literature. To present the first case of subelectrode hematoma without subdural component that was detected during invasive EEG monitoring after subdural electrode implantation. A 19-year-old female with drug resistant seizures was decided to undergo invasive monitoring with subdural electrodes. While good quality recordings had been initially obtained from all electrodes placed on the right parietal convexity, no cerebral cortical activity could be obtained from one electrode 2 days after the first operation. Explorative surgery revealed a circumscribed subelectrode hematoma without a subdural component. Awareness of the potential complications of subdural electrode implantation and close follow-up of the clinical findings of the patient are of highest value for early detection and successful management.

    Aquaporin 1 (AQP1) is a molecular water channel expressed in many anatomical locations, particularly in epithelial barriers specialized in water transport. The aim of this study was to investigate AQP1 expression in chronic subdural hematoma (CSDH) membranes. In this preliminary study, 11 patients with CSDH underwent burr hole craniectomy and drainage. Membrane specimens were stained with a monoclonal antibody targeting AQP1 for immunohistochemical analysis. The endothelial cells of the sinusoid capillaries of the outer membranes exhibited an elevated immunoreactivity to AQP1 antibody compared to the staining intensity of specimens from the inner membrane and normal dura. These findings suggest that the outer membrane might be the source of the increased fluid accumulation responsible for chronic hematoma enlargement.

    Spontaneous muscle hematomas are a common and serious complication of anticoagulant treatment. The incidence of this event has increased along with the rise in the number of patients receiving anticoagulants. Radiological management is both diagnostic and interventional. Computed tomography angiography (CTA) is the main tool for the detection of hemorrhage to obtain a positive, topographic diagnosis and determine the severity. Detection of an active leak of contrast material during the arterial or venous phase is an indication for the use of arterial embolization. In addition, the interventional radiological procedure can be planned with CTA. Arterial embolization of the pedicles that are the source of the bleeding is an effective technique. The rate of technical and clinical success is 90% and 86%, respectively. Copyright © 2015 Éditions françaises de radiologie. Published by Elsevier Masson SAS. All rights reserved.

    To examine whether surgical decompression of hematomas by capsulotomy can help to improve long-term renal function following extracorporeal shock wave lithotripsy (SWL). This study retrospectively identified 7 patients who underwent capsulotomy for post SWL renal hematomas between 2008 and 2012. The control group comprised 8 conservatively treated patients. The median follow-up time was 22 months. The two groups were comparable in age, gender, body mass index, risk factors for developing hematomas (renal failure, urinary flow impairment, indwelling ureteral stent and diabetes mellitus) and the selected SWL modalities. Hematoma size was also similar. However, significantly more patients in the surgical group had purely intracapsular hematomas (85.7% vs. 37.5%) without a potentially pressure-relieving capsular rupture. There were no significant differences in the post-interventional drop in hemoglobin, rise in retention parameters or drop in glomerular filtration rate (GFR). No capsulotomy-related complications were observed, but surgery required a significantly longer hospital stay than conservative management (median, 9 days vs. 5 days). The two groups also showed comparable recovery of renal function at long-term follow-up (median change in GFR from baseline, 97.1% and 97.8%, respectively). Since renal function did not differ between the two treatment groups, the conservative management remains the standard treatment for post-SWL renal hematoma.

    Spontaneous hematoma refractory to conservative management is a potentially serious condition that requires prompt diagnosis and intervention. The purpose of this study was to evaluate the performance of computed tomography (CT) in the treatment planning and to report the effectiveness of transcatheter embolization with N-butyl-2-cyanoacrylate (NBCA). Forty-one interventions in 38 patients within a 12-year period were evaluated. CT and angiograms were reviewed for the location of the hematoma, the presence of extravasation, and the correlation of CT and angiography findings. Arterial extravasation was present on 34/39 CT scans. Angiograms confirmed the CT scans in 29 cases. Angiograms revealed extravasation in four cases which CT showed venous bleeding (n = 2) or no bleeding (n = 2). Five patients with arterial and 1 patient with venous extravasation on CT images had no extravasation on angiograms. Embolization was performed to all arteries with extravasation on angiograms. Empiric embolization of the corresponding artery on the CT was performed when there was no extravasation on angiograms. Embolization procedures were performed with 15 % NBCA diluted with iodized oil. Technical success was achieved in 40/41 (97.6 %) interventions. Clinical success was achieved in 35 patients with a single, in 1 patient with 2, and in 1 patient with 3 interventions. No complications related to embolization procedure occurred. None of the patients died due to a progression of the hematoma. NBCA is an effective and safe embolic agent to treat hematoma refractory to conservative management. Contrast-enhanced CT may provide faster and more effective intervention. Retrospective.

    Spontaneous spinal epidural hematoma (SSEH) has been reported as a rare cause of spinal cord compression, especially in children. Clinical features are usually nonspecific, although cervicothoracic location of hematoma could be presented with progressive paraplegia. Guillian-Barré syndrome (GBS) is clinically defined as an acute peripheral neuropathy causing progressive limb weakness. Because SSEH and GBS have very similar signs and symptoms, SSEH could be misdiagnosed as GBS. Nevertheless, they can be presented together. We describe a rare case of SSEH coexisting with GBS.

    Rapidly resolving acute subdural hematomas (RRASDHs) have been described in case reports and case series but are still poorly understood. We hypothesized that a cohort analysis would confirm previously reported predictors of RRASDH including coagulopathy, additional intracranial hemorrhage, and low-density band on imaging. We also hypothesized that rapid resolution would be associated with improved trauma outcomes. We reviewed all nonoperative acute subdural hematomas (ASDHs) treated at our center from 2011 to 2015. Inclusion criteria were ASDH on computed tomography (CT), admission Glasgow coma score >7, and repeat CT to evaluate ASDH change. RRASDH was defined as reduced hematoma thickness by 50% within 72 h. Clinical data, CT findings, and trauma end points were analyzed for the RRASDH and nonresolving groups. There were 154 ASDH patients included, with 29 cases of RRASDH. The RRASDH group had a lower rate of comorbidities than the nonresolving group (58.6% versus 78.4%, P = 0.03) and a lower rate of prehospital anticoagulation (7.7% versus 37.1%, P = 0.004). Previously reported predictors of RRASDH did not differ between the groups, nor did any clinical outcome measures. When compared with patients who experienced rapid growth (>50% increased width in 72 h), the RRASDH group had lower mortality (3.4% versus 23.5%, P = 0.04). To our knowledge, this is the largest review of RRASDHs. We identified two previously unrecognized factors that may predict resolution; however, previously reported predictors were not associated with resolution. We also found no relationship between RRASDHs and improved standard trauma outcomes, calling into question the clinical significance of RRASDH. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Intraoperative Ultrasonography during Drainage for Chronic Subdural Hematomas: A Technique to Release Isolated Deep-seated Hematomas—Technical Note

    2015-01-01

    After the drainage of chronic subdural hematomas (CSDHs), residual isolated deep-seated hematomas (IDHs) may recur. We introduce intraoperative ultrasonography to detect and remove such IDHs. Intra-operative ultrasonography is performed with fine transducers introduced via burr holes. Images obtained before dural opening show the CSDHs, hyper- and/or hypoechoic content, and mono- or multilayers. Images are also acquired after irrigation of the hematoma under the dura. Floating hyperechoic spots (cavitations) on the brain cortex created by irrigation confirm the release of all hematoma layers; areas without spots represent IDHs. Their overlying thin membranes are fenestrated with a dural hook for irrigation. Ultrasonographs were evaluated in 43 CSDHs (37 patients); 9 (21%) required IDH fenestration. On computed tomography scans, 17 were homogeneous-, 6 were laminar-, 16 were separated-, and 4 were trabecular type lesions. Of these, 2 (11.8%), 3 (50%), 4 (25%), and 0, respectively, manifested IDHs requiring fenestration. There were no technique-related complications. Patients subjected to IDH fenestration had lower recurrence rates (11.1% vs. 50%, p = 0.095) and required significantly less time for brain re-expansion (mean 3.78 ± 1.62 vs. 18 ± 5.54 weeks, p = 0.0009) than did 6 patients whose IDHs remained after 48 conventional irrigation and drainage procedures. Intraoperative ultrasonography in patients with CSDHs facilitates the safe release of hidden IDHs. It can be expected to reduce the risk of postoperative hematoma recurrence and to shorten the brain re-expansion time. PMID:26345671

    Although vocal cord paralysis (VCP) following thyroidectomy is primarily associated with surgical trauma, it is not the sole etiology. Vocal cord paralysis following thyroidectomy can be caused by a vocal cord hematoma with an incidence of 1.4% due to direct injury during orotracheal intubation. In this article, we present a case of VCP caused by vocal cord hematoma. A 32-year-old male patient who has been receiving propylthiouracil treatment for toxic multinodular goiter since 10 years was admitted to our hospital to be operated because of persisting complaints. The patient was hospitalized for sutureless thyroidectomy after he became euthyroid. Preoperative fiberoptic laryngoscopy performed by the ear, nose, and throat department revealed bilaterally motile vocal folds and a completely open airway. Patient underwent sutureless total thyroidectomy with a vessel sealing device (Ligasure TM LF1212, Covidien, CO), and a minivac drainage system was placed in the thyroid lodge. On the morning of the first postoperative day, 50 mL of serosanguinous fluid was drained. The patient's voice was normal, and there was no ecchymosis. Postoperative fiberoptic laryngoscopy revealed a hematoma near the right vocal fold and paralysis of the right vocal fold; however, the airway was open. It should be kept in mind that VCP is not solely due to surgery but can also result from intubation, as observed in this case.

    Abdominal rectus sheath hematoma (ARSH) is a rare clinical condition that can be confused with other causes of acute abdomen. We report an 83-year-old woman receiving antiplatelet medication who presented with ARSH following a cough episode. The patient was hospitalized with a diagnosis of acute chronic obstructive pulmonary disease exacerbations. During hospital stay, sudden onset abdominal pain was developed following a severe cough episode. Computed tomography of the abdomen revealed ARSH. Rectus sheath hematoma is a rare and often misdiagnosed clinical condition. It is important to be considered for the diagnosis. ARSH should be considered in case of development of acute abdominal pain following cough in receiving anticoagulant or antiplatelet therapy. © 2014 John Wiley & Sons Ltd.

    To analyze the effects of kinesio taping (KT) -applied with three different strains that induced or not the formation of skin creases (called convolutions)- on color intensity of post-surgical superficial hematomas. Single-blind paired study. Rehabilitation clinic. A convenience sample of 13 inpatients with post-surgical superficial hematomas. The tape was applied for 24 consecutive hours. Three tails of KT were randomly applied with different degrees of strain: none (SN); light (SL); and full longitudinal stretch (SF). We expected to obtain correct formation of convolutions with SL, some convolutions with SN, and no convolutions with SF. The change in color intensity of hematomas, measured by means of polar coordinates CIE L*a*b* using a validated and standardized digital images system. Applying KT to hematomas did not significantly change the color intensity in the central area under the tape (p > 0.05). There was a significant treatment effect (p < 0.05) under the edges of the tape, independently of the formation of convolutions (p > 0.05). The changes observed along the edges of the tape could be related to the formation of a pressure gradient between the KT and the adjacent area, but were not dependent on the formation of skin convolutions.

    A 19-year-old female with sickle cell anemia (SCD) was referred to our hospital after two days of hospitalization at another hospital for a headache crisis. This headache crisis was due to a raised intracranial pressure; these symptoms were noted and included in her comprehensive list of symptoms. There was an acute drop in the hemoglobin and hematocrit levels. The cranial CT scan demonstrated a left fronto-parietal acute epidural hematoma (AEH) and a calvarial bone expansion, which was suggestive of medullary hematopoiesis. The patient underwent emergent craniotomy and evacuation of the hematoma. There were no abnormal findings intra-operatively apart from the AEH, except skull thickening and active petechial bleeding from the dural arteries. Repeated CT scan showed a complete evacuation of the hematoma. The possible underlying pathophysiological mechanisms were discussed. In addition to the factors mentioned in the relevant literature, any active petechial bleeding from the dural arteries on the separated surface of the dura from the skull could have contributed to the expanding of the AEH in our patient. Neurosurgeons and other health care providers should be aware of spontaneous AEH in patients with SCD. Copyright © 2013 Sociedad Española de Neurocirugía. Published by Elsevier España.

    We report a case showing delayed hemothorax superimposed on extrapleural hematoma after blunt chest injury. The patient was a 56-year-old man with a medical history of alcoholic hepatopathy who presented with a chief complaint of dyspnea on exertion. One month prior to presentation, he had sustained a fall that had resulted in left simple rib fracture. A chest radiograph taken at the time of injury showed notable reduction in the permeability of the left lung field along with high pulmonary collapse as well as rightward deviation of the shadow of the inferior mediastinum. Chest CT images showed a region of low absorption in the thoracic cavity with septi. Thoracic drainage was performed (1,300 mL total) and hemothorax was diagnosed. Thoracoscopic examination was then performed. When the inside of the thorax was observed, what had been presumed to be the septi of a multilocular fluid collection was found to be actually the parietal pleura, and a hematoma was confirmed inside the extrapleural cavity. The hematoma inside the extrapleural cavity was managed with lavage and drainage, and drainage tubes were placed inside both the thoracic cavity and extrapleural cavity at the end of the procedure. The patient's postoperative course was uneventful, and he was discharged on postoperative day 4.

    To investigate whether, after the publication of grade I evidence that it reduces recurrence rates, the practice of drain insertion after burr-hole drainage of chronic subdural hematoma has changed. Further, we aimed to document various practice modalities concerning the insertion of a drain adopted by neurosurgeons internationally. We administered a survey to neurosurgeons worldwide with questions relating to the surgical treatment of chronic subdural hematoma, with an emphasis on their practices concerning the use of a drain. The preferred surgical technique was burr-hole drainage (89%). Most surgeons prefer to place a drain (80%), whereas in 56% of the cases the reason for not placing a drain was brain expansion after evacuation. Subdural drains are placed by 50% and subperiosteal drains by 27% of the responders, whereas 23% place primarily a subdural drain if possible and otherwise a subperiosteal drain. Three quarters of the responders leave the drain for 48 hours and give prophylactic antibiotic treatment, mostly a single-shot dose intraoperatively (70%). Routine postoperative computed tomography is done by 59% mostly within 24-48 hours after surgery (94%). Adjunct treatment to surgery rarely is used (4%). The publication of grade I evidence in favor of drain use influenced positively this practice worldwide. Some surgeons are still reluctant to insert a drain, especially when the subdural space is narrow after drainage of the hematoma. The insertion of a subperiosteal drain could be a good alternative solution. However, its outcome and efficacy must be evaluated in larger studies. Copyright © 2017 Elsevier Inc.

    To determine the prevalence of subdural hematoma (SDH) in patients presenting with primary nontraumatic lobar intracerebral hemorrhage (ICH) and characteristics associated with the presence of SDH. Retrospective analysis of data collected in a prospective cohort study. Hospital. Consecutive sample of 200 patients with primary lobar ICH and 75 patients with deep hemispheric ICH. Presence of SDH and mortality. Subdural hematoma was present in 40 of 200 patients (20%) with primary lobar ICH. By contrast, SDH was not present in any of 75 consecutive patients with deep hemispheric ICH (P < .001 for comparison with lobar ICH). Intracerebral hemorrhage volume higher than 60 cm3 was the only independent predictor of SDH (odds ratio [OR], 2.69; 95% confidence interval [CI], 1.14-6.34; P = .02). Subdural hematoma thickness more than 5 mm was an independent predictor of increased 30-day mortality (OR, 7.60; 95% CI, 1.86-30.99; P = .005) after controlling for other factors including ICH volume. Further analysis showed that the effect of SDH on mortality depended on ICH volume, with larger odds for mortality in those with low ICH volume (OR, 12.85; 95% CI, 2.42-68.23; P = .003 for those with ICH volume <30 cm3). Cerebral amyloid angiopathy was present in 8 of 9 patients with pathological specimens. Nontraumatic SDH frequently accompanies primary lobar ICH and is associated with higher 30-day mortality, particularly when the ICH volume is relatively low. Rupture of an amyloid-laden leptomeningeal vessel, with extravasation into the brain parenchyma and subdural space, may be the pathogenic mechanism.

    To identify the current management modalities practiced by neurosurgeons in India for chronic subdural hematoma. A questionnaire was prepared for the survey and sent via e-mail to neurosurgeons. It covered the following aspects of managing chronic subdural hematoma: 1) demographic and institutional details; 2) choice of surgical procedure; 3) surgical adjutants such as placing a subdural drain; 4) pre- and postoperative care; and 5) recurrences and management. Responses obtained were entered in a SPSS data sheet and analyzed. Response rate of the survey was 9.3%. The majority of neurosurgeons (75%) preferred to do burr whole drainage for primary chronic subdural hematoma and also for recurrences. Only one third of routinely placed a subdural drain. Considerable practice variations exist for medical and perioperative management. Bedside twist drill drainage, which is effective and less costly than operative room procedures, has not gained popularity in practice. The present survey points towards the importance of making management guidelines for this common neurosurgical entity. Copyright © 2016 Elsevier Inc. All rights reserved.

    The computed tomography angiography (CTA) spot sign is a validated biomarker for poor outcome and hematoma expansion in intracerebral hemorrhage. The spot sign has proven to be a dynamic entity, with multimodal imaging proving to be of additional value. We investigated whether the addition of a 90-second delayed CTA acquisition would capture additional intracerebral hemorrhage patients with the spot sign and increase the sensitivity of the spot sign. We prospectively enrolled consecutive intracerebral hemorrhage patients undergoing first pass and 90-second delayed CTA for 18 months at a single academic center. Univariate and multivariate logistic regression were performed to assess clinical and neuroimaging covariates for relationship with hematoma expansion and mortality. Sensitivity of the spot sign for hematoma expansion on first pass CTA was 55%, which increased to 64% if the spot sign was present on either CTA acquisition. In multivariate analysis the spot sign presence was associated with significant hematoma expansion: odds ratio, 17.7 (95% confidence interval, 3.7-84.2; P=0.0004), 8.3 (95% confidence interval, 2.0-33.4; P=0.004), and 12.0 (95% confidence interval, 2.9-50.5; P=0.0008) if present on first pass, delayed, or either CTA acquisition, respectively. Spot sign presence on either acquisitions was also significant for mortality. We demonstrate improved sensitivity for predicting hematoma expansion and poor outcome by adding a 90-second delayed CTA, which may enhance selection of patients who may benefit from hemostatic therapy. © 2014 American Heart Association, Inc.

    To investigate parameters associated with hematoma enlargement in non-vitamin K antagonist oral anticoagulant (NOAC)-related intracerebral hemorrhage (ICH). This retrospective cohort study includes individual patient data for 190 patients with NOAC-associated ICH over a 5-year period (2011-2015) at 19 departments of neurology across Germany. Primary outcome was the association of prothrombin complex concentrate (PCC) administration with hematoma enlargement. Subanalyses were calculated for blood pressure management and its association with the primary outcome. Secondary outcomes include associations with in-hospital mortality and functional outcome at 3 months assessed using the modified Rankin Scale. The study population for analysis of primary and secondary outcomes consisted of 146 NOAC-ICH patients with available follow-up imaging. Hematoma enlargement occurred in 49/146 (33.6%) patients with NOAC-related ICH. Parameters associated with hematoma enlargement were blood pressure ≥ 160mmHg within 4 hours and-in the case of factor Xa inhibitor ICH-anti-Xa levels on admission. PCC administration prior to follow-up imaging was not significantly associated with a reduced rate of hematoma enlargement either in overall NOAC-related ICH or in patients with factor Xa inhibitor intake (NOAC: risk ratio [RR] = 1.150, 95% confidence interval [CI] = 0.632-2.090; factor Xa inhibitor: RR = 1.057, 95% CI = 0.565-1.977), regardless of PCC dosage given or time interval until imaging or treatment. Systolic blood pressure levels < 160mmHg within 4 hours after admission were significantly associated with a reduction in the proportion of patients with hematoma enlargement (RR = 0.598, 95% CI = 0.365-0.978). PCC administration had no effect on mortality and functional outcome either at discharge or at 3 months. In contrast to blood pressure control, PCC administration was not associated with a reduced rate of hematoma enlargement in NOAC-related ICH

    In legal medicine, reliable localization and analysis of hematomas in subcutaneous fatty tissue is required for forensic reconstruction. Due to the absence of ionizing radiation, magnetic resonance imaging (MRI) is particularly suited to examining living persons with forensically relevant injuries. However, there is limited experience regarding MRI signal properties of hemorrhage in soft tissue. The aim of this study was to evaluate MR sequences with respect to their ability to show high contrast between hematomas and subcutaneous fatty tissue as well as to reliably determine the volume of artificial hematomas. Porcine tissue models were prepared by injecting blood into the subcutaneous fatty tissue to create artificial hematomas. MR images were acquired at 3T and four blinded observers conducted manual segmentation of the hematomas. To assess segmentability, the agreement of measured volume with the known volume of injected blood was statistically analyzed. A physically motivated normalization taking into account partial volume effect was applied to the data to ensure comparable results among differently sized hematomas. The inversion recovery sequence exhibited the best segmentability rate, whereas the T1T2w turbo spin echo sequence showed the most accurate results regarding volume estimation. Both sequences led to reproducible volume estimations. This study demonstrates that MRI is a promising forensic tool to assess and visualize even very small amounts of blood in soft tissue. The presented results enable the improvement of protocols for detection and volume determination of hemorrhage in forensically relevant cases and also provide fundamental knowledge for future in-vivo examinations.

Based on a literature review of 50 cases of spontaneous cervical epidural hematomas, we concluded that the relatively high frequency of hemiparesis (12 of 50 cases, 24%) is the result of the fact that epidural hematomas are predominantly distributed dorsolaterally in the region of the mid and lower cervical spine, leading to unilateral cervical cord compression. Clinicians should keep in mind that acute hemiparesis can be caused by spontaneous cervical epidural hematomas for which intravenous thrombolysis is contraindicated.

    Objective To determine the prevalence of subdural hematoma (SDH) in patients presenting with primary non-traumatic lobar intracerebral hemorrhage (ICH) and characteristics associated with the presence of SDH. Design Retrospective analysis of data collected in a prospective cohort study. Setting Hospital. Patients Consecutive sample of 200 patients with primary lobar ICH and 75 patients with deep hemispheric ICH. Main Outcome Measures Presence of SDH and mortality. Results Subdural hematoma was present in 40 of 200 patients (20%) with primary lobar ICH. By contrast, SDH was not present in any of 75 consecutive patients with deep hemispheric ICH (P<.001 for comparison with lobar ICH). Intracerebral hemorrhage volume higher than 60 cm3 was the only independent predictor of SDH (odds ratio [OR], 2.69; 95% confidence interval [CI], 1.14–6.34; P=.02). Subdural hematoma thickness more than 5 mm was an independent predictor of increased 30-day mortality (OR, 7.60; 95% CI, 1.86–30.99; P=.005) after controlling for other factors including ICH volume. Further analysis showed that the effect of SDH on mortality depended on ICH volume, with larger odds for mortality in those with low ICH volume (OR, 12.85; 95% CI, 2.42–68.23; P=.003 for those with ICH volume <30 cm3). Cerebral amyloid angiopathy was present in 8 of 9 patients with pathological specimens. Conclusions Nontraumatic SDH frequently accompanies primary lobar ICH and is associated with higher 30-day mortality, particularly when the ICH volume is relatively low. Rupture of an amyloid-laden leptomeningeal vessel, with extravasation into the brain parenchyma and subdural space, may be the pathogenic mechanism. PMID:19139303

    We report on a 72-year-old male patient who developed a nontraumatic spinal subdural hematoma (SSDH) during rivaroxaban therapy, a relatively new orally administered direct factor Xa inhibitor. The patient sustained a sudden onset of interscapular pain, followed by gait impairment and paraplegia. Magnetic resonance imaging (MRI) of the spine demonstrated SSDH from T6 to T8. Laboratory tests revealed a high rivaroxaban level, associated with a major hemorrhagic risk. Surgery was, therefore, performed the following morning, after normalization of coagulation parameters. Determining the time of safe surgery remains challenging when hemorrhagic complications happen with direct factor Xa inhibitor, especially when neurological prognosis is engaged. Spinal subdural hematoma has not previously been reported following rivaroxaban therapy.

    The presence of active contrast extravasation at CTA predicts hematoma expansion and in-hospital mortality in patients with nontraumatic intracerebral hemorrhage. This study aims to determine the frequency and predictive value of the contrast extravasation in patients with aSDH. We retrospectively reviewed 157 consecutive patients who presented to our emergency department over a 9-year period with aSDH and underwent CTA at admission and a follow-up NCCT within 48 hours. Two experienced readers, blinded to clinical data, reviewed the CTAs to assess for the presence of contrast extravasation. Medical records were reviewed for baseline clinical characteristics and in-hospital mortality. aSDH maximum width in the axial plane was measured on both baseline and follow-up NCCTs, with hematoma expansion defined as >20% increase from baseline. Active contrast extravasation was identified in 30 of 199 discrete aSDHs (15.1%), with excellent interobserver agreement (κ = 0.80; 95% CI, 0.7-0.9). The presence of contrast extravasation indicated a significantly increased risk of hematoma expansion (odds ratio, 4.5; 95% CI, 2.0-10.1; P = .0001) and in-hospital mortality (odds ratio, 7.6; 95% CI, 2.6-22.3; P = 0.0004). In a multivariate analysis controlled for standard risk factors, the presence of contrast extravasation was an independent predictor of aSDH expansion (P = .001) and in-hospital mortality (P = .0003). Contrast extravasation stratifies patients with aSDH into those at high risk and those at low risk of hematoma expansion and in-hospital mortality. This distinction could affect patient treatment, clinical trial selection, and possible surgical intervention.

    Erythrolysis occurs in the clot after intracerebral hemorrhage (ICH) and the release of hemoglobin causes brain injury but it is unclear when such lysis occurs. The present study examined early erythrolysis in rats. ICH rats had an intra-caudate injection of 100 µl autologous blood and sham rats had a needle insertion. All rats had T2 and T2* MRI scanning and brains were used for histology and CD163 (a hemoglobin scavenger receptor) and DARPP-32 (a neuronal marker) immunohistochemistry. There was marked heterogeneity within the hematoma on T2* MRI, with a hyper- or isointense core and a hypointense periphery. Hematoxylin and eosin staining in the same animals showed significant erythrolysis in the core with the formation of erythrocyte ghosts. The degree of erythrolysis correlated with the severity of perihematomal neuronal loss. Perihematomal CD163 was increased by day 1 after ICH and may be involved in clearing hemoglobin caused by early hemolysis. Furthermore, ICH resulted in more severe erythrolysis, neuronal loss and perihematomal CD163 upregulation in spontaneously hypertensive rats compared to Wistar Kyoto rats. In conclusions, T2*MRI detectable early erythrolysis occurred in the clot after ICH, and activated CD163. Hypertension is associated with enhanced erythrolysis in the hematoma. PMID:27783383

    The majority of acute post-traumatic subdural hematomas (ASDH) require urgent surgical evacuation. Spontaneous resolution of ASDH has been reported in some cases. We report here on a case of a patient with a large amount of ASDH that was rapidly reduced. A 61-yr-old man was found unconscious following a high speed motor vehicle accident. On initial examination, his Glasgow Coma Score scale was 4/15. His pupils were fully dilated and non-reactive to bright light. Brain computed tomography (CT) showed a massive right-sided ASDH. The decision was made to treat him conservatively because of his poor clinical condition. Another brain CT approximately 14 hr after the initial scan demonstrated a remarkable reduction of the previous ASDH and there was the new appearance of high density in the subdural space adjacent to the falx and the tentorium. Thirty days after his admission, brain CT revealed chronic SDH and the patient underwent surgery. The patient is currently able to obey simple commands. In conclusion, spontaneous rapid resolution/reduction of ASDH may occur in some patients. The mechanisms are most likely the result of dilution by cerebrospinal fluid and the redistribution of hematoma especially in patients with brain atrophy.

    The authors report the case of a 13-year-old patient with neurofibromatosis (NF-I), who suffered blunt trauma to the left tibia in 1993. The diagnosis of subperiosteal hematoma was made. Treatment consisted of temporary rest. There was a recurrence in 1996, and the subperiosteal hematoma was drained. In 1997, a shortening osteotomy of the left tibia was performed. However, massive gigantism with elephantiasis of the left leg remained, causing a serious functional and cosmetic problem. In 1999, the leg was amputated above the knee. The literature is reviewed and 7 case reports are compared. The pathogenesis of subperiosteal hematoma is discussed.

    Chronic subdural hematoma (CSDH) and symptomatic subdural hygroma are common diseases that require neurosurgical management. Burr hole trephination is the most popular surgical treatment for CSDH and subdural hygroma because of a low recurrence rate and low morbidity compared with craniotomy with membranectomy, and twist-drill craniotomy. Many reports suggest that placing a catheter in the subdural space for drainage can further reduce the rate of recurrence; however, complications associated with this type of drainage include acute subdural hematoma, cortical injury, and infection. Remote hemorrhage due to overdrainage of cerebrospinal fluid (CSF) is another possible complication of burr hole trephination with catheter drainage that has rarely been reported. Here, we present 2 cases of remote hemorrhages following burr hole trephination with catheter drainage for the treatment of CSDH and symptomatic subdural hygroma. One patient developed intracerebral hemorrhage and subarachnoid hemorrhage in the contralateral hemisphere, while another patient developed remote hemorrhage 3 days after the procedure due to the sudden drainage of a large amount of subdural fluid over a 24-hour period. These findings suggest that catheter drainage should be carefully monitored to avoid overdrainage of CSF after burr hole trephination.

    We have been developing the CAD scheme for head and abdominal injuries for emergency medical care. In this work, we have developed an automated method to detect typical head injuries, rupture or strokes of brain. Extradural and subdural hematoma region were detected by comparing technique after the brain areas were registered using warping. We employ 5 normal and 15 stroke cases to estimate the performance after creating the brain model with 50 normal cases. Some of the hematoma regions were detected correctly in all of the stroke cases with no false positive findings on normal cases.

    The clinic use of alpha Lipoic Acid (ALA) is linked to its capability to exert antioxidant effects and, more interestingly, to counteract the pathologic changes of complex networks of cytokines, chemokines and growth factors, restoring their physiological state. The aim of this randomized controlled clinical trial was to test the contribution of oral supplementation of ALA to the standard treatment with Progesterone vaginal suppositories, in healing subchorionic hematomas in patients with threatened miscarriage. Controls were administered only Progesterone suppositories. Nineteen pregnant women in the first trimester of gestation, with threatened miscarriage and ultrasound evidence of subchorionic hematoma, were included in the trial and randomly divided in two groups: controls, treated with 400 mg Progesterone (200 mg 2 times per day), given by vaginal suppositories, and case study treated with the same Progesterone dosage, plus ALA, given orally at the dose of 600 mg (300 mg 2 times per day, DAV®, Lo.Li. Pharma srl, Italy). Sixteen patients completed the trial. Treatment was performed until complete resolution of the clinical picture. In both groups, the subjects improved significantly but, in general, a better and faster evolution in the major signs of threatened miscarriage was observed in the subjects treated with ALA and Progesterone. In these patients, the speed of resorption of subchorionic hematoma was significantly (p ≤ 0.05) superior compared to controls. The ALA and Progesterone group showed a faster decrease or disappearance of all symptoms than that observed in the control group, however the difference was not significant. These preliminary results suggest that ALA supplementation significantly contributes to speed up the process of restoration of physiological conditions in threatened miscarriage and ameliorates the medical conditions of both the mothers and the foetus, probably modulating the networks of cytokines, growth factors and other

  11. Investigating the Relationship between Cerebrospinal Fluid and Magnetic Induction Phase Shift in Rabbit Intracerebral hematoma expansion Monitoring by MRI.

    In a prior study of intracerebral hemorrhage monitoring using magnetic induction phase shift (MIPS), we found that MIPS signal changes occurred prior to those seen with intracranial pressure. However, the characteristic MIPS alert is not yet fully explained. Combining the brain physiology and MIPS theory, we propose that cerebrospinal fluid (CSF) may be the primary factor that leads to hematoma expansion being alerted by MIPS earlier than with intracranial pressure monitoring. This paper investigates the relationship between CSF and MIPS in monitoring of rabbit intracerebral hemorrhage models, which is based on the MIPS measurements data, the quantified data on CSF from medical images and the amount of injected blood in the rabbit intracerebral hemorrhage model. In the investigated results, a R value of 0.792 with a significance of 0.019 is observed between the MIPS and CSF, which is closer than MIPS and injected blood. Before the reversal point of MIPS, CSF is the leading factor in MIPS signal changing in an early hematoma expansion stage. Under CSF compensation, CSF reduction compensates for hematoma expansion in the brain to keep intracranial pressure stable. MIPS decrease results from the reducing CSF volume. This enables MIPS to detect hematoma expansion earlier than intracranial pressure.

    Detection of dural hematoma based on multi-channel near-infrared differential absorbance has the advantages of rapid and non-invasive detection. The location and number of detectors around the light source are critical for reducing the pathological characteristics of the prediction model on dural hematoma degree. Therefore, rational selection of detector numbers and their distances from the light source is very important. In this paper, a detector position screening method based on Variable Importance in the Projection (VIP) analysis is proposed. A preliminary modeling based on Partial Least Squares method (PLS) for the prediction of dural position μ a was established using light absorbance information from 30 detectors located 2.0-5.0 cm from the light source with a 0.1 cm interval. The mean relative error (MRE) of the dural position μ a prediction model was 4.08%. After VIP analysis, the number of detectors was reduced from 30 to 4 and the MRE of the dural position μ a prediction was reduced from 4.08% to 2.06% after the reduction in detector numbers. The prediction model after VIP detector screening still showed good prediction of the epidural position μ a . This study provided a new approach and important reference on the selection of detector location in near-infrared dural hematoma detection.

    Traumatic spinal subdural hematoma involving the retroclival region and upper cervical spine is a rare pathology. To our knowledge, there have only been 2 prior cases in an adult trauma patient. We describe a patient with preexisting Chiari 1 malformation, who recently sustained a unilateral type 1 occipital condyle fracture with associated disruption of the tectorial membrane and transverse ligament, which returned with a retroclival subdural hematoma extending down to C7, causing spinal cord compression and symptomatic obstructive hydrocephalus. A 30-year-old female sustained a motor vehicle collision. Computed tomography C spine revealed a type I occipital condyle fracture. Magnetic resonance imaging C spine demonstrated disruption of the tectorial membrane and avulsion of the transverse ligament at its attachment to the left C1 tubercle; moreover, there was a Chiari 1 malformation. The patient was neurologically intact. A halo was recommended, but the patient opted for an aspen collar with close management. She was discharged but returned 3 days later with apneic episodes, along with bradycardia and hypertension. She was promptly intubated. Computed tomography head showed interval ventricular enlargement. Magnetic resonance imaging C spine revealed a new ventral hematoma spanning the retroclival region to C7, most pronounced at C2-C3. On examination, she opened her eyes to pain, her pupils were equal and reactive, and she withdrew in all extremities. An external ventricular drain was emergently placed. She underwent a suboccipital craniectomy, C1-3 laminectomies, and occiput-C4 instrumented fusion. The dura was significantly tense, and no epidural hematoma was observed during lateral exploration. Postoperatively, she woke up well, exhibiting a nonfocal neurologic examination. A diagnostic angiogram was negative. She was extubated uneventfully, and the external ventricular drain was weaned off in 4 days. Traumatic spinal subdural hematoma involving both the

    Heyde syndrome is known as a triad of calcific aortic stenosis, anemia due to gastrointestinal bleeding from angiodysplasia, and acquired type 2A von Willebrand disease. This acquired hemorrhagic disorder is characterized by the loss of the large von Willebrand factor multimers due to the shear stress across the diseased aortic valve. The most frequently observed type of bleeding in these patients is mucosal or skin bleeding, such as epistaxis, followed by gastrointestinal bleeding. On the other hand, intracranial hemorrhage complicating Heyde syndrome is extremely rare. A 77-year-old woman presented to our hospital with severe aortic stenosis and severe anemia due to gastrointestinal bleeding and was diagnosed with Heyde syndrome. Although aortic valve replacement was performed without recurrent gastrointestinal bleeding, postoperative life-threatening acute subdural hematoma occurred with a marked midline shift. Despite prompt surgical evacuation of the hematoma, she did not recover consciousness and she died 1 month after the operation. Postoperative subdural hematoma is rare, but it should be kept in mind as a devastating hemorrhagic complication, especially in patients with Heyde syndrome.

    Acute subdural hematoma (ASDH) is associated with high morbidity and mortality. Whether the volume effect of the hematoma and increase of intracranial pressure (ICP) or the local effect of blood are responsible for this severe pathophysiology is unclear. Therefore, we compared subdural infusion of autologous blood and paraffin oil in a rat model of ASDH. In a histological study, we investigated the effects on acute ICP, cerebral perfusion pressure (CPP), cerebral blood flow (CBF), tissue oxygen changes, and brain damage at 2, 24, and 96 h post-infusion. Inflammatory reaction was analyzed by immuno-staining for microglia (ionized calcium binding adaptor molecule 1 [Iba1]) and activated astrocytes (glial fibrillary acidic protein [GFAP]). Besides acute ICP and CBF changes, we investigated the development of behavior (neuroscore and beamwalk test) for up to 4 days after injury in a behavioral study. Despite comparably increased ICP, there was a more pronounced lesion growth in the blood infusion group during the first 96 h. Further, there was an increased peri-lesional immunoreactive area of Iba1 and GFAP 96 h post-infusion, primarily in the blood infusion group, whereas hippocampal damage was comparable in both infusion groups. In the behavioral evaluation, paraffin-infused animals showed a better recovery, compared with the blood infusion group. In conclusion, comparable acute time-course of ICP, CPP, and CBF clearly indicates that the differences in lesion size, inflammatory reaction, and behavioral deficits after blood- and paraffin oil-induced ASDH are partially due to blood constituents. Therefore, current data suggest that subdural hematomas should be completely removed as quickly as possible; decompression alone may not be sufficient to prevent secondary brain damage.

    The patient with epidural hematoma and cerebral herniation has a good prognosis with immediate drainage, but a poor prognosis with delay to decompression. Such patients who present to nonneurosurgical hospitals are commonly transferred without drainage to the nearest neurosurgical center. This practice has never been demonstrated to be the safest approach to treating these patients. A significant minority of emergency physicians (EPs) have advised and taught bedside burr hole drainage or skull trephination before transfer for herniating patients. The objective of this study was to assess the effect of nonneurosurgeon drainage on neurologic outcome in patients with cerebral herniation from epidural hematoma. A structured literature review was performed using EMBASE, the Cochrane Library, and the Emergency Medicine Abstracts database. No evidence meeting methodologic criteria was found describing outcomes in patients transferred without decompressive procedures. For patients receiving local drainage before transfer, 100% had favorable outcomes. Although the total number of patients is small and the population highly selected, the natural history of cerebral herniation from epidural hematoma and the best available evidence suggests that herniating patients have improved outcomes with drainage procedures before transport. © 2010 by the Society for Academic Emergency Medicine.

    Rectus sheath hematoma (RSH) presenting as acute surgical abdomen is a rare clinical entity. Failing to establish an early diagnosis will probably result in increased morbidity or unnecessary surgical intervention. We describe herein a case of an 85-year-old woman receiving anticoagulants who presented with typical clinical manifestations of acute surgical abdomen and a slightly palpable abdominal mass. Ultrasonography was inconclusive whereas computed tomography scans demonstrated a large right rectus sheath hematoma associated with hemoperitoneum. The patient was treated conservatively with success. It is therefore concluded that RSH must be considered in any elderly patient on anticoagulant therapy who presents with manifestations of acute surgical abdomen.

    The initial inflammatory phase of bone fracture healing represents a critical step for the outcome of the healing process. However, both the mechanisms initiating this inflammatory phase and the function of immune cells present at the fracture site are poorly understood. In order to study the early events within a fracture hematoma, we established an in vitro fracture hematoma model: we cultured hematomas forming during an osteotomy (artificial bone fracture) of the femur during total hip arthroplasty (THA) in vitro under bioenergetically controlled conditions. This model allowed us to monitor immune cell populations, cell survival and cytokine expression during the early phase following a fracture. Moreover, this model enabled us to change the bioenergetical conditions in order to mimic the in vivo situation, which is assumed to be characterized by hypoxia and restricted amounts of nutrients. Using this model, we found that immune cells adapt to hypoxia via the expression of angiogenic factors, chemoattractants and pro-inflammatory molecules. In addition, combined restriction of oxygen and nutrient supply enhanced the selective survival of lymphocytes in comparison with that of myeloid derived cells (i.e., neutrophils). Of note, non-restricted bioenergetical conditions did not show any similar effects regarding cytokine expression and/or different survival rates of immune cell subsets. In conclusion, we found that the bioenergetical conditions are among the crucial factors inducing the initial inflammatory phase of fracture healing and are thus a critical step for influencing survival and function of immune cells in the early fracture hematoma.

    The clinical signs of heart masses tend to be nonspecific, generally depending more on their repercussions on heart function caused by their location rather than on their type. Imaging techniques make it possible to limit the differential diagnosis of heart masses based on their location, morphology, and characteristics of echogenicity, density, or intensity, depending on the technique used to study them. We present the case of a woman with squeezing mid chest pain irradiating to her shoulder and positive cardiac markers in whom a left atrial mass was identified at echocardiography. This finding was confirmed at chest CT. The signs at chest CT were compatible with a mural hematoma and this diagnosis was confirmed after intraoperative biopsy. Copyright © 2011 SERAM.

    Spontaneous spinal epidural hematoma (SSEH) is a rare clinical entity, most often with acute symptomatic spinal cord compression and potentially permanent neurologic deficits. SSEH usually has surgical solutions and a good outcome after hematoma evacuation. A 61-year-old professional weight-lifting coach presented to the emergency department with sudden back pain, rapidly progressive paraparesis, and neurogenic bladder, after an intense training, 5 h previously. Magnetic resonance imaging revealed a ventral thoracic epidural hematoma with significant compression at Th3-Th6. Surgical procedure was performed within the first 12 h: decompressive laminectomy from Th3 to Th7 vertebral levels and near total epidural hematoma removal. The patient improved rapidly from Th5 AIS-C to Th7 AIS-D paraplegia with independent ambulation, after the intervention. The rehabilitation program led to further improvement of the neurologic deficits and a favorable outcome, to AIS-E. Weightlifting has been reported as SSEH precipitating factor in young athletes. Our case is unique however, because the athlete was older. The underlying pathophysiological mechanism is represented by intravenous pressure changes and bleeding of the epidural venous plexus during a prolonged Valsalva maneuver, induced by strenuous, repeated efforts. Spondylosis, hypertension, and low doses of aspirin were incriminated as risk factors for SSEH. Prompt diagnosis, emergent decompressive intervention, early rehabilitation, and secondary prophylaxis were essential for a good outcome.

There were 47 cases of PGH with an incidence of 1 in 762 deliveries. Patients with PGH were younger, more likely to be nulliparous and had a greater weight gain during pregnancy than the control group. Patients with PGH had a longer first and second stage of labor than the control group. Mediolateral episiotomy and operative delivery were more frequently performed in patients with PGH than the control group. Neonates born to mothers with PGH were heavier than the control group (3525 ± 428 versus 3325 ± 579; p = 0.031). In the logistic regression model, nulliparity (OR: 8.68, 95% CI = 2.96-25.3), instrumental delivery (OR: 7.96, 95% CI = 1.37-49.0) and mediolateral episiotomy (OR: 6.67, 95% CI = 2.61-17.1) were factors which had an independent impact on risk of PGH. Nulliparity, instrumental delivery and mediolateral episiotomy are the main risk factors for hematomas.

    Chronic subdural hematoma (cSDH) is an increasingly common neurological disease process. Despite the wide prevalence of cSDH, there remains a lack of consensus regarding numerous aspects of its clinical management. We provide an overview of the epidemiology and pathophysiology of cSDH and discuss several controversial management issues, including the timing of post-operative resumption of anticoagulant medications, the effectiveness of anti-epileptic prophylaxis, protocols for mobilization following evacuation of cSDH, as well as the comparative effectiveness of the various techniques of surgical evacuation. A PubMed search was carried out through October 19, 2010 using the following keywords: "subdural hematoma", "craniotomy", "burr-hole", "management", "anticoagulation", "seizure prophylaxis", "antiplatelet", "mobilization", and "surgical evacuation", alone and in combination. Relevant articles were identified and back-referenced to yield additional papers. A meta-analysis was then performed comparing the efficacy and complications associated with the various methods of cSDH evacuation. There is general agreement that significant coagulopathy should be reversed expeditiously in patients presenting with cSDH. Although protocols for gradual resumption of anti-coagulation for prophylaxis of venous thrombosis may be derived from guidelines for other neurosurgical procedures, further prospective study is necessary to determine the optimal time to restart full-dose anti-coagulation in the setting of recently drained cSDH. There is also conflicting evidence to support seizure prophylaxis in patients with cSDH, although the existing literature supports prophylaxis in patients who are at a higher risk for seizures. The published data regarding surgical technique for cSDH supports primary twist drill craniostomy (TDC) drainage at the bedside for patients who are high-risk surgical candidates with non-septated cSDH and craniotomy as a first-line evacuation technique for c

    Rapid, on-the-spot diagnostic and monitoring systems are vital for the survival of patients with intracranial hematoma, as their conditions drastically deteriorate with time. To address the limited accessibility, high costs and static structure of currently used MRI and CT scanners, a portable non-invasive multi-slice microwave imaging system is presented for accurate 3D localization of hematoma inside human head. This diagnostic system provides fast data acquisition and imaging compared to the existing systems by means of a compact array of low-profile, unidirectional antennas with wideband operation. The 3D printed low-cost and portable system can be installed in an ambulance for rapid on-site diagnosis by paramedics. In this paper, the multi-slice head imaging system's operating principle is numerically analysed and experimentally validated on realistic head phantoms. Quantitative analyses demonstrate that the multi-slice head imaging system is able to generate better quality reconstructed images providing 70% higher average signal to clutter ratio, 25% enhanced maximum signal to clutter ratio and with around 60% hematoma target localization compared to the previous head imaging systems. Nevertheless, numerical and experimental results demonstrate that previous reported 2D imaging systems are vulnerable to localization error, which is overcome in the presented multi-slice 3D imaging system. The non-ionizing system, which uses safe levels of very low microwave power, is also tested on human subjects. Results of realistic phantom and subjects demonstrate the feasibility of the system in future preclinical trials.

    The etiology of chronic subdural hematoma (CSDH) in patients is diverse. The primary objective of this article was to discuss one of the causes, spontaneous intracranial hypotension with spinal cerebrospinal fluid (CSF) leak, which is usually neglected by the neurosurgeon. All the consecutive 15 patients who underwent operation for CSDHs between June 2012 and June 2014 at Sir Run Run Shaw Hospital of Zhejiang University were included in this retrospective cohort study. The clinical and imaging data of these patients with CSDHs due to spinal CSF leak were retrospectively studied. Fifteen patients, with a mean age of 53.8 ± 8.3 years, underwent operations for CSDH. Hematomas were unilateral in 4 patients and bilateral in 11 patients. Among these patients, eight patients had recurrence of hematomas after operation due to neglect of spinal CSF leak. All patients had fully recovery. Spinal CSF leak is a cause of cSDH, which is overlooked by the doctor.

    PubMed Central

    2013-01-01

    A 77-year-old man who had undergone mitral valve replacement 5 years previously presented with an intrapericardial mass. Computed tomography and magnetic resonance imaging showed that the mass lesion contained hematoma components. Positron-emission tomography (PET) with 2-[18 F] fluoro-2-deoxy-d-glucose (FDG) revealed uptake in the peripheral rim of the mass. These findings suggested the presence of hematoma associated with a malignant lesion. Surgical resection was performed, and the histological diagnosis was chronic expanding intrapericardial hematoma without neoplastic changes. Chronic expanding intrapericardial hematoma is a rare disease but should be considered when an expanding mass is found in a patient after cardiac surgery. The FDG-PET findings of chronic expanding hematomas, including FDG uptake in the peripheral rim of the mass as a result of inflammation, should be recognized as a potential interpretive pitfall that mimics a malignant tumor.

    Objective There are few studies comparing small and large craniotomies for the initial treatment of chronic subdural hematoma (CSDH) which had non-liquefied hematoma, multilayer intrahematomal loculations, or organization/calcification on computed tomography and magnetic resonance imaging. These procedures were compared to determine which would produce superior postoperative results. Methods Between 2001 and 2009, 317 consecutive patients were surgically treated for CSDH at our institution. Of these, 16 patients underwent a small craniotomy with partial membranectomy and 42 patients underwent a large craniotomy with extended membranectomy as the initial treatment. A retrospective review was performed to compare the postoperative outcomes of these two techniques, focusing on improvement of neurological status, complications, reoperation rate, and days of post-operative hospitalization. Results The mean ages were 69.4±12.1 and 55.6±9.3 years in the small and large craniotomy groups, respectively. The recurrence of hematomas requiring reoperation occurred in 50% and 10% of the small and large craniotomy patients, respectively (p<0.001). There were no significant differences in postoperative neurological status, complications, or days of hospital stay between these two groups. Conclusion Among the cases of CSDH initially requiring craniotomy, the large craniotomy with extended membranectomy technique reduced the reoperation rate, compared to that of the small craniotomy with partial membranectomy technique.

    Spontaneous spinal epidural hematoma during pregnancy is a quite rare event requiring emergent decompressive surgery in the majority of cases to prevent permanent neurological damage. Therefore, there is little data in the literature regarding anesthetic management of cervical localization during pregnancy. The potential for difficult airway management with the patient under general anesthesia is one of the major concerns that needs to be addressed to prevent further cord compression. Anesthetic management should also include measures to maintain the mean arterial pressure to improve spinal cord perfusion. Furthermore, spine surgery in pregnant patients needs special consideration in terms of positioning and in the postoperative period. We present a case of a 35-year-old white woman at 21 weeks of gestation with a spontaneous cervical epidural hematoma. Fiberoptic bronchoscope-guided nasal intubation was a safe option to ensure a higher rate of successful endotracheal intubation while minimizing the risk of aggravating the injury. Her care posed other multiples challenges that required a multidisciplinary team approach. The case of our patient serves as a reminder of this rare condition and its implications regarding anesthesia.

    Craniotomy has been accepted as the treatment of choice for the management of acute epidural hematomas (AEDH). However, in practice, it seems possible to evacuate AEDH via a single burr hole instead of the traditional craniotomy in certain circumstances. Among 160 patients with AEDH meeting criteria for evacuation admitted to the emergency and accident division of our center between 2006 and 2009, we found 8 cases of hematoma appearing isodense to brain parenchyma on computed tomography (CT), who had concomitant coagulopathy. These patients were managed by burr-hole drainage for treatment of the liquefied AEDH. A closed drainage system was then kept in the epidural space for 3 days. In all 8 patients, AEDH was evacuated successfully via burr-hole placement over the site of hematoma. The level of consciousness and other symptoms improved within the first day, and no patient required an additional routine craniotomy. For patients with slowly-developing AEDH in the context of impaired coagulation, burr-hole evacuation and drainage might be a less invasive method of treatment compared to conventional craniotomy.

    Alpha Lipoic Acid (ALA) is a safe natural molecule that exerts a selective immunomodulating activity with antioxidant and anti-inflammatory properties. This randomized controlled clinical trial (RCT) tested the effect of the vaginal administration with ALA or Progesterone, in subchorionic hematoma resorption in women with threatened miscarriage. 400 mg of vaginal Progesterone or 10 mg of vaginal ALA were administered to sixty-two pregnant women, in the first trimester of gestation with threatened miscarriage and subchorionic hematoma. Controls were patients who chose not to receive any treatment. In the ALA group the subchorionic hematoma was reabsorbed more quickly in comparison with the progression detected in Progesterone group (p ≤ 0.05). The other parameters checked (pelvic pain and vaginal bleeding) did not show any significant difference and a smaller number of miscarriages was recorded in the ALA group, compared to Progesterone group. Our data provides the first evidence of the efficacy of ALA, administered by vaginal route, in the healing process of patients with threatened miscarriage, thus supporting the normal course of pregnancy.

    2011-01-01

    Background Previously proposed classifications for carotid plaque and cerebral parenchymal hemorrhages are used to estimate the age of hematoma according to its signal intensities on T1w and T2w MR images. Using these classifications, we systematically investigated the value of cardiovascular magnetic resonance (CMR) in determining the age of vessel wall hematoma (VWH) in patients with spontaneous cervical artery dissection (sCAD). Methods 35 consecutive patients (mean age 43.6 ± 9.8 years) with sCAD received a cervical multi-sequence 3T CMR with fat-saturated black-blood T1w-, T2w- and TOF images. Age of sCAD was defined as time between onset of symptoms (stroke, TIA or Horner's syndrome) and the CMR scan. VWH were categorized into hyperacute, acute, early subacute, late subacute and chronic based on their signal intensities on T1w- and T2w images. Results The mean age of sCAD was 2.0, 5.8, 15.7 and 58.7 days in patients with acute, early subacute, late subacute and chronic VWH as classified by CMR (p < 0.001 for trend). Agreement was moderate between VWH types in our study and the previously proposed time scheme of signal evolution for cerebral hemorrhage, Cohen's kappa 0.43 (p < 0.001). There was a strong agreement of CMR VWH classification compared to the time scheme which was proposed for carotid intraplaque hematomas with Cohen's kappa of 0.74 (p < 0.001). Conclusions Signal intensities of VWH in sCAD vary over time and multi-sequence CMR can help to determine the age of an arterial dissection. Furthermore, findings of this study suggest that the time course of carotid hematomas differs from that of cerebral hematomas. PMID:22122756

    The aim of this retrospective study is to evaluate the efficacy and incidence of complications of craniotomy and membranectomy in elderly patients for the treatment of organized chronic subdural hematoma (OCSH). We retrospectively reviewed a series of 28 consecutive patients suffering from OCSH, diagnosed by magnetic resonance imaging (MRI) or computer tomography (CT) to establish the degree of organization and determine the intrahematomal architecture including inner membrane ossification. The indication to perform a primary enlarged craniotomy as initial treatment for nonliquefied OCSH with multilayer loculations was based on the hematoma MRI appearance - mostly hyperintense in both T1- and T2-weighted images with a hypointense web- or net-like structure within the hematoma cavity or inner membrane calcification CT appearance - hyperdense. These cases have been treated by a large craniotomy with extended membranectomy as the initial treatment. However, the technique of a burr hole with closed system drainage for 24-72 h was chosen for cases of nonseptated and mostly liquefied Chronic Subdural Hematoma (CSDH). Between 1998 and 2015, 148 consecutive patients were surgically treated for CSDH at our institution. Of these, 28 patients which have OSDH underwent a large craniotomy with extended membranectomy as the initial treatment. The average age of the patients was 69 (69.4 ± 12.1). Tension pneumocephalus (TP) has occurred in 22.8% of these patients ( n = 28). Recurring subdural hemorrhage (RSH) in the operation area has occurred in 11.9% of these patients in the first 24 h. TP with RSH was seen in 4 of 8 TP patients (50%). Large epidural air was seen in one case. Postoperative seizures requiring medical therapy occurred in 25% of our patients. The average stay in the department of neurosurgery was 11 days, ranging from 7 to 28 days. Four patients died within 28 days after surgery; mortality rate was 14.28%.

    2017-01-01

    Abstract Rectus sheath hematoma (RSH) is an increasingly common clinical condition in our hospitals due to the increasing use of anticoagulant therapies for various purposes among our patients. Treatment of spontaneous RSH is generally conservative. For continued bleeding, interventional radiologic identification and subsequent embolization is an effective option. Surgery usually involves significant morbidity and is considered a technique of last resort. In this case report, we describe the case of middle aged female who developed abdominal compartment syndrome (ACS) from a large RSH that had extended into the retroperitoneum. The patient underwent abdominal decompression with removal of the hematoma and subsequently fared very well. Patients with large RSHs extending into the retroperitoneum should undergo constant monitoring of their abdominal pressures for early detection and treatment of potentially deadly condition of ACS.

    Calcified chronic subdural hematoma (CCSDH), or "armored brain," is a rare disease entity. The optimal surgical procedure for CCSDH has not been established because it is hard to obtain brain re-expansion after surgery. In particular, a large CCSDH is difficult to completely extirpate, and the residual rigid inner and outer membranes facilitates dead space retention and hematoma recurrence. We introduce the use a multiple suturing technique to tent the residual outer and inner membranes onto the dura matter so as to obliterate dead space after surgical treatment for CCSDH. Neuroimaging and surgical reports with illustrative images from two cases are shown. Two patients were admitted to our intensive care unit more than 10 years apart from their ventriculoperitoneal (V-P) shunt placements. The first patient presented with clinical signs of increased intracranial pressure. The second patient had a large CCSDH as a concomitant finding with ruptured aneurysmal subarachnoid hemorrhage. Computerized cranial tomography demonstrated large hematoma cavities with thick calcified inner membranes. After neurosurgical intervention by craniotomy and optimal resection of calcified membranes and muddy blood clot, we tented the residual calcified inner and outer membranes onto the dura matter by multiple sutures to reduce dead space accumulation. Postoperatively, the two patients had improved clinical symptoms along with much reduced hematoma cavity in imaging examinations. We reported an alternative technique using multiple tenting procedures to improve dead space obliteration after surgical treatment for patients with a large CCSDH presenting as a late complication after V-P shunting.

    Objective Chronic subdural hematoma (CSDH) is relatively common in neurosurgical field. However not all patients develop CSDH after minor head trauma. In this study, we evaluate the risk factors of post-traumatic CSDH. Methods Two-hundred and seventy-seven patients were enrolled and analyzed in this study from January 2012 to December 2013. Of those, 20 participants had minor head trauma developed CSDH afterward. We also included 257 patients with minor head trauma who did not develop CSDH during the same follow-up period as the control group. We investigated the risk factors related to the development of CSDH after minor head trauma. Results Old age (p=0.014), preexisting diabetes mellitus (p=0.010), hypertension (p=0.026), history of cerebral infarction (p=0.035), antiplatelet agents (p=0.000), acute subdural hematoma in the convexity (p=0.000), encephalomalacia (p=0.029), and long distance between skull and brain parenchyma (p=0.000) were significantly correlated with the development of CSDH after trauma. Multivariate analysis revealed that only the maximum distance between the skull and the cerebral parenchyma was the independent risk factor for the occurrence of CSDH (hazard ratio 2.55, p=0.000). Conclusion We should consider the possibility of developing CSDH in the post-traumatic patients with the identified risk factors. PMID:27169043

    Chronic subdural hematoma (CSDH) is the most frequent type of intracranial hemorrhage which especially affects the elderly. Various surgical techniques have been reported for CSDH treatment; optimal treatment methods are still controversial. In this study, the effects of long drainage durations on results and recurrences were investigated in patients on whom closed system drainage with burr hole craniotomy was applied due to CSDH. 90 patients with 105 CSDH were operated between 2008 and 2016. Patients were divided into two groups based on the duration of drainage. Group A (n = 40) was determined as 2-4 days of closed-system drainage, while Group B (n = 50) was recorded as 5-7 days of closed-system drainage. Recurrence was defined as accumulation of blood in the operation area and recurrence of symptoms within the monitoring period of six months. Recurrence was observed in 7 (15.6) of the Group A patients and 2 (3.3%) of the Group B patients. There was a statistically significant difference between groups in terms of recurrence rate (p = 0.04). Postoperative thickness of hematoma was measured in the first month follow-up computerized tomography. There was a statistically significant difference between groups in terms of postoperative thickness of residual hematoma (p = 0.05). 2-4 days of closed system drainage following burr hole craniotomy is an effective and reliable choice of treatment in CSDH. Nevertheless, increasing the duration of drainage to 5-7 days provided better results without increasing the risk of complication.

    The presence of intracerebral hematoma from aneurysm rupture is an indication for craniotomy for clot evacuation and aneurysm clipping. Some centers have begun securing aneurysms with coil embolization followed by clot evacuation in the operating room. This approach requires transporting a patient from the angiography suite to the operating room, which can take valuable time and resources. To report our experience with 3 cases in which a novel technique for minimally invasive evacuation of intracerebral hematomas after endovascular treatment of ruptured intracranial aneurysms was used. The Penumbra Apollo system can be used in the angiography suite in conjunction with neuroendovascular techniques to simultaneously address a symptomatic hematoma associated with a ruptured aneurysm. Standard preoperative computed tomography angiography was performed on arrival to the emergency department. The patients underwent diagnostic cerebral angiography followed by balloon-assisted coil embolization and then remained in the neurointerventional suite for intracerebral hematoma evacuation with the Apollo system. All patients tolerated coil embolization and hematoma evacuation well. The combined procedures lasted <3 hours in both cases. Two patients were eventually discharged to acute rehabilitation facilities less than a month after their initial insult, and 1 has been cleared to return to work. The other patient was transferred to hospice care. The Apollo aspiration system appears to be a safe and effective minimally invasive option for intracerebral hematoma evacuation, particularly when coupled with endovascular embolization of ruptured intracranial aneurysms. Future work will address which patient population is most likely to benefit from this promising technique.

    Background The computed tomography angiography (CTA) spot sign represents active contrast extravasation within acute primary intracerebral hemorrhage (ICH) and is an independent predictor of hematoma expansion (HE) and poor clinical outcomes. The spot sign could be detected on first-pass CTA (fpCTA) or delayed CTA (dCTA). Purpose To investigate the additional benefits of dCTA spot sign in primary ICH and hematoma size for predicting spot sign. Material and Methods This is a retrospective study of 100 patients who underwent non-contrast CT (NCCT) and CTA within 24 h of onset of primary ICH. The presence of spot sign on fpCTA or dCTA, and hematoma size on NCCT were recorded. The spot sign on fpCTA or dCTA for predicting significant HE, in-hospital mortality, and poor clinical outcomes (mRS ≥ 4) are calculated. The hematoma size for prediction of CTA spot sign was also analyzed. Results Only the spot sign on dCTA could predict high risk of significant HE and poor clinical outcomes as on fpCTA ( P < 0.05). With dCTA, there is increased sensitivity and negative predictive value (NPV) for predicting significant HE, in-hospital mortality, and poor clinical outcomes. The XY value (product of the two maximum perpendicular axial dimensions) is the best predictor (area under the curve [AUC] = 0.82) for predicting spot sign on fpCTA or dCTA in the absence of intraventricular and subarachnoid hemorrhage. Conclusion This study clarifies that dCTA imaging could improve predictive performance of CTA in primary ICH. Furthermore, the XY value is the best predictor for CTA spot sign.

    For chronic subdural hematoma, placement of a Blake drain with a two-burr-hole craniotomy is often preferred. However, the placement of such drains carries the risk of penetrating the brain surface or damaging superficial venous structures. To describe the use of a Nelaton catheter for the placement of a subdural drain in two-burr-hole trephination for chronic subdural hematoma. A Nelaton catheter was used to guide placement of a Blake drain into the subdural hematoma cavity and provide irrigation of the hematoma cavity. With the two-burr-hole method, the Nelaton catheter could be removed easily via the frontal burr hole after the Blake drain was in place. We used the Nelaton catheters in many surgical procedures and found it a safe and easy technique. This method allows the surgeon to safely direct the catheter into the correct position in the subdural space. This tool has two advantages. First, the use of a small and flexible Nelaton catheter is a safe method for irrigation of a chronic subdural hematoma cavity. Second, in comparison with insertion of subdural drainage alone through a burr hole, the placement of the Nelaton catheter in subdural space is easier and the risk of damaging relevant structures such as cortical tissue or bridging veins is lower. Thus this technique may help to avoid complications when placing a subdural drain. Georg Thieme Verlag KG Stuttgart · New York.

Objective The objective of this article is to employ a ratio of CSF volume to brain volume for longitudinal assessment of space-volume relationships in patients with extra-axial hematoma and to determine variability of the ratio among patients with different types and stages of hematoma. Patients and methods In our retrospective study, we reviewed 113 patients with surgical extra-axial hematomas. We included 28 patients (age 61.7 +/- 17.7 years; 19 males, nine females) with an acute epidural hematoma (EDH) ( n = 5) and subacute/chronic subdural hematoma (SDH) ( n = 23). We excluded 85 patients, in order, due to acute SDH ( n = 76), concurrent intraparenchymal pathology ( n = 6), and bilateral pathology ( n = 3). Noncontrast CT images of the head were obtained using a CT scanner (2004 GE LightSpeed VCT CT system, tube voltage 140 kVp, tube current 310 mA, 5 mm section thickness) preoperatively, postoperatively (3.8 ± 5.8 hours from surgery), and at follow-up clinic visit (48.2 ± 27.7 days after surgery). Each CT scan was loaded into an OsiriX (Pixmeo, Switzerland) workstation to segment pixels based on radiodensity properties measured in Hounsfield units (HU). Based on HU values from -30 to 100, brain, CSF spaces, vascular structures, hematoma, and/or postsurgical fluid were segregated from bony structures, and subsequently hematoma and/or postsurgical fluid were manually selected and removed from the images. The remaining images represented overall brain volume-containing only CSF spaces, vascular structures, and brain parenchyma. Thereafter, the ratio between the total number of voxels representing CSF volume (based on values between 0 and 15 HU) to the total number of voxels

    Background and Purpose In primary intracerebral hemorrhage (ICH), the presence of contrast extravasation following CT angiography (CTA), termed the ‘spot sign’, predicts hematoma expansion and mortality. Since the biological underpinnings of the spot sign are not fully understood, we investigated whether the rate of contrast extravasation - which may reflect the rate of bleeding - predicts expansion and mortality beyond the simple presence of the spot sign. Methods Consecutive ICH patients with first-pass CTA followed by a 90-second delayed post-contrast CT (delayed CTA) were included. CTAs were reviewed for spot sign presence by two blinded readers. Spot sign volumes on first-pass and delayed CTA and ICH volumes were measured using semi-automated software. Extravasation rates were calculated and tested for association with hematoma expansion and mortality using uni- and multivariable logistic regression. Results 162 patients were included, 48 (30%) of whom had ≥1 spot sign. Median spot sign volume was 0.04mL on first-pass CTA and 0.4mL on delayed CTA. Median extravasation rate was 0.23mL/min overall, and 0.30mL/min among expanders versus 0.07mL/min in non-expanders. Extravasation rates were also significantly higher in patients who died in hospital: 0.27mL/min versus 0.04mL/min. In multivariable analysis, the extravasation rate was independently associated with in-hospital mortality (OR1.09 [95%CI 1.04–1.18], p=0.004), 90-day mortality (OR1.15 [95%CI 1.08–1.27], p=0.0004), and hematoma expansion (OR1.03 [95%CI 1.01–1.08], p=0.047). Conclusions Contrast extravasation rate, or spot sign growth, further refines the ability to predict hematoma expansion and mortality. Our results support the hypothesis that the spot sign directly measures active bleeding in acute ICH. PMID:26243220

    The levels of several coagulation factors, able to influence hemostatic balance, display circadian variations. We hypothesized that the onset and extent of hematoma expansion (HE) following intracerebral hemorrhage (ICH) also display diurnal patterns. We reviewed clinical, laboratory, and radiological data from 111 consecutive patients with spontaneous ICH who had baseline head computed tomography (CT) scans within 3 h of ICH onset and follow-up CT during the following 72 h. We defined any HE (AHE) as any increase in hematoma volume from baseline to follow-up CT and significant HE (SHE) as an absolute increase in hematoma volume >6 mL or relative increase >33%. We categorized the patients into 2 groups based on the timing of the initial CT scans--day group (from 0800 to 2000 h) and night group (from 2000 to 0800 h)--and performed logistic regression analyses. We also analyzed the differences in the rates of HE between the groups during six 4-h periods spanning 24 h, using χ(2) tests. We found that the rates of AHE and SHE were higher in the day versus night group (75% vs. 48%; p = 0.009 for AHE and 47.6% vs. 25.9%; p = 0.047 for SHE). On multivariable logistic regression, day group assignment was independently associated with AHE (adjusted odds ratio = 3.53; p = 0.008) but not with SHE. Both AHE and SHE peaked in the early afternoon (1200-1600 h) and reached a nadir during the 2000 to 2400 h time period, and they were significantly different between the time periods (0000-0400, 0400-0800, 0800-1200, 1200-1600, 1600-2000, and 2000-2400 h); p = 0.002 and 0.029, respectively. These exploratory findings support the presence of a daily pattern in the occurrence of HE, with a higher risk during the day hours. Our results could have implications for future therapeutic efforts targeting HE in ICH and for the triage of ICH patients. They require further validation. © 2015 The Author(s).

    Objective: The aim of this retrospective study is to evaluate the efficacy and incidence of complications of craniotomy and membranectomy in elderly patients for the treatment of organized chronic subdural hematoma (OCSH). Materials and Methods: We retrospectively reviewed a series of 28 consecutive patients suffering from OCSH, diagnosed by magnetic resonance imaging (MRI) or computer tomography (CT) to establish the degree of organization and determine the intrahematomal architecture including inner membrane ossification. The indication to perform a primary enlarged craniotomy as initial treatment for nonliquefied OCSH with multilayer loculations was based on the hematoma MRI appearance – mostly hyperintense in both T1- and T2-weighted images with a hypointense web- or net-like structure within the hematoma cavity or inner membrane calcification CT appearance - hyperdense. These cases have been treated by a large craniotomy with extended membranectomy as the initial treatment. However, the technique of a burr hole with closed system drainage for 24–72 h was chosen for cases of nonseptated and mostly liquefied Chronic Subdural Hematoma (CSDH). Results: Between 1998 and 2015, 148 consecutive patients were surgically treated for CSDH at our institution. Of these, 28 patients which have OSDH underwent a large craniotomy with extended membranectomy as the initial treatment. The average age of the patients was 69 (69.4 ± 12.1). Tension pneumocephalus (TP) has occurred in 22.8% of these patients (n = 28). Recurring subdural hemorrhage (RSH) in the operation area has occurred in 11.9% of these patients in the first 24 h. TP with RSH was seen in 4 of 8 TP patients (50%). Large epidural air was seen in one case. Postoperative seizures requiring medical therapy occurred in 25% of our patients. The average stay in the department of neurosurgery was 11 days, ranging from 7 to 28 days. Four patients died within 28 days after surgery; mortality rate was 14.28%. Conclusion

    The pseudo-random modulation/near IR sensor (PRM/NIR Sensor) is a low cost portable system designed for time-resolved tissue diagnosis, especially hematoma detection in the emergency care facility. The sensor consists of a personal computer and a hardware unit enclosed in a box of size 37 X 37 X 31 cm3 and of weight less than 10 kg. Two pseudo-random modulated diode lasers emitting at 670 nm and 810 nm are used in the sensor as light sources. The sensor can be operated either in a single wavelength mode or a true differential mode. Optical fiber bundles are used for convenient light delivery and color filters are used to reject room light. Based on a proprietary resolution- enhancement correlation technique, the system achieves a time resolution better than 40 ps with a PRM modulation speed of 200 MHz and a sampling rate of 1-10 Gs/s. Using the prototype sensor, phantom experiments have been conducted to study the feasibility of the sensor. Brain's optical properties are simulated with solutions of intralipid and ink. Hematomas are simulated with bags of paint and hemoglobin immersed in the solution of varies sizes, depths, and orientations. Effects of human skull and hair are studied experimentally. In animal experiment, the sensor was used to monitor the cerebral oxygenation change due to hypercapnia, hypoxia, and hyperventilation. Good correlations were found between NIR measurement parameters and physiological changes induced to the animals.

    Chronic subdural hematoma (CSDH) has a variety of clinical presentations, with numerous neurological symptoms and signs. Hemiparesis is one of the leading signs that potentially indicates CSDH. Purpose of this study was to determine the threshold (cut-off) value of midsagittal line (MSL) shift after which hemiparesis is likely to appear. The study evaluated 83 patients with 53 unilateral and 30 bilateral CSDHs in period of three years. Evaluated computed tomography (CT) findings in patients with CSDH were diameter of the hematoma and midsagittal line shift, measured on non-contrast CT scan in relation with occurrence of hemiparesis. Threshold values of MSL shift for both types of CSDHs were obtained as maximal (equal) sensitivity and specificity (intersection of the curves). MSL is a good predictor for hemiparesis occurrence (total sample, AUROC 0.75, p=0.0001). Unilateral and bilateral CSDHs had different threshold values of the MSL for hemiparesis development. Results suggested that in unilateral CSDH the threshold values of MSL could be at 10 mm (AUROC=0.65; p=0.07). For bilateral CSDH the threshold level of MSL shift was 4.5 mm (AUROC=0.77; p=0.01). Our study pointed on the phenomenon that midsagittal line shift can predict hemiparesis occurrence. Hemiparesis in patients with bilateral CSDH was more related to midsagittal line shift compared with unilateral CSDH. When value of midsagittal line shift exceed the threshold level, hemiparesis occurs with certain probability.

    Objective This report describes the characteristics and impact of subdural hematoma (SDH) after labor epidural analgesia. Case Reports Eleven obstetric patients had subdural hematomas (SDH) associated with the use of labor epidural analgesia over 7 years at a tertiary care hospital. Ten of 11 patients had signs consistent with post-dural puncture headache (PDPH) prior to the diagnosis of SDH. Five patients (45%) had a recognized unintentional dural puncture, 1 (9%) had a combined spinal-epidural with a 24-gauge needle, and 5 (45%) had no recognized dural puncture. For 10 of the 11 cases, SDH was diagnosed an average of 4.1 (range 1–7) days after performance of labor epidural analgesia; one case was diagnosed at 25 days. Ten of 11 (91%) cases had a second hospital stay for an average of 2.8 (range 2–4) days for observation, without further requirement for neurosurgical intervention. One case (9%) had decompressive hemicraniectomy after becoming unresponsive. The observed rate of labor epidural analgesia-associated SDH was 0.026% (11 in 42,969, about 1:3900), and the rate of SDH was 1.1% (5 in 437, about 1:87) if a recognized dural puncture occurred during epidural catheter placement. Conclusions SDH after labor epidural anesthesia is rare, but potentially more common than historically estimated. Cases of PDPH after labor epidural anesthesia should be monitored closely for severe neurologic signs and symptoms that could herald SDH. PMID:27512937

    This study aims to compare the curative effect of different treatment methods of hypertensive putamen hemorrhage, in order to determine an ideal method of treatment; and to explore the curative effect of the application of soft channel technology-minimally invasive liquefaction and drainage of intracerebral hematoma in the treatment of hypertensive putamen hemorrhage. Patients with hypertensive cerebral hemorrhage, who were treated in our hospital from January 2015 to January 2016, were included into this study. Patients were divided into three groups: minimally invasive drainage group, internal medical treatment group and craniotomy group. In the minimally invasive drainage group, puncture aspiration and drainage were performed according to different hematoma conditions detected in brain CT, the frontal approach was selected for putamen and intracerebral hemorrhage, and drainage was reserved until the hematoma disappeared in CT detection. Drug therapy was dominated in the internal medical treatment group, while surgery under general anesthesia was performed to remove the hematoma in the craniotomy group. Post-treatment neurological function defect scores in minimally invasive drainage group and internal medical group were 16.14 ± 11.27 and 31.43 ± 10.42, respectively; and the difference was remarkably significant (P< 0.01). Post-treatment neurological function defect scores in the minimally invasive drainage group and craniotomy group were 16.14 ± 11.27 and 24.20 ± 12.23, respectively; and the difference was statistically significant (P< 0.05). There was a remarkable significant difference in ADL1-2 level during followed-up in survival patients between the minimally invasive drainage group and internal medical treatment group (P< 0.01), and there was a significant difference in followed-up mortality between these two groups (P< 0.01). Clinical observation and following-up results revealed that minimally invasive drainage treatment was superior to internal

    The optimal management of spontaneous intracerebral hemorrhage (ICH), especially if deep-seated, remains a matter of discussion. Lysis of the blood clot applying recombinant tissue-type plasminogen activator (rtPA) by an intrahematomal catheter is a minimally invasive treatment option, currently being under investigation in a randomized trial. The center position of the catheter in the hematoma is believed to be crucial for an optimal clot lysis. To achieve this objective, frame-based stereotaxy and frameless stereotaxy with guidance of an articulated arm were used. Recently, a preregistered stylet for direct navigation, alleviating the need of guidance, became available. In this study, we evaluated the relative error (RE) describing the deviation of the catheter from the ideal center position in the clot and compared the accuracy of catheter placement using frameless stereotaxy or the novel preregistered stylet. The intrahematomal catheter position was evaluated in three dimensions in 89 patients with spontaneous supratentorial ICH. Frameless stereotaxy with guidance of an articulated arm was performed in 50 patients. The preregistered stylet was used in 39 patients. The catheter position was evaluated using a RE calculating the distance perpendicular to the center of the catheter in relation to the hematoma's diameter. The mean hematoma volume was 51.4 ml. Forty-four out of 89 hematomas were deep-seated. Intraventricular blood was found in 59 patients. The RE of the catheter position was lower in the stylet group in comparison to the frameless stereotaxy group (mean 0.57 vs. 0.90; p = 0.0018). There was no difference between deep-seated and lobar hematomas with regard to the accuracy of catheter placement (p = 0.62). The RE is a robust measure for describing intrahematomal catheter position. The preregistered stylet facilitates a satisfactory catheter placement and is a viable alternative to frameless stereotaxy and guidance with the articulated arm.

    We report an interesting case in which overt aortic dissection mimicked two episodes of aortic intramural hematoma (IMH) (Stanford A, DeBakey I). This took place over the course of four days and had a major influence on the surgical treatment strategy. The first episode of IMH regressed completely within 15 hours after it was clinically diagnosed and verified using imaging techniques. The recurrence of IMH was detected three days thereafter, resulting in an urgent surgical intervention. Overt aortic dissection with evidence of an intimal tear was diagnosed intraoperatively.

    Acute intracerebral hemorrhage (ICH) is associated with increased susceptibility to bacterial infection. The physiopathology of this phenomenon is not very clear. We conducted a prospective observational study investigating the correlation and independent predictors of infections in patients with ICH. Patients admitted between April 1997 and June 2013 with ICH diagnosis were evaluated for inclusion and exclusion criteria. Two hundred twenty-two patients were included in this study. Ninety four patients (42.6%) presented with an infection during hospitalization being more common than pneumonia (30%) and urinary tract infections (14%). Intraventricular hemorrhage (IVH) (95% confidence interval [CI], 62.7% versus 39.3%; P < .001) and higher ICH score (95% CI, 2.31% versus 1.67%; P = .0014) were more common in patients who had infections. We found the following risk factors for having an infection in patients with ICH: IVH (odds ratio [OR] 2.3; 95% IC, 1.3-4.1), each point of ICH score (OR 1.3; 95% CI, 1.1-1.6), and having a hematoma volume larger than 30 cc (OR 2.0; 95% CI, 1.1-3.5). The localization of the hematoma was not found to be relevant. ICH score, size of the hematoma, and presence of IVH are independent risk factors for having an infection after ICH.

    We present a case of intramural duodenal hematoma as a complication of endoscopic therapy for a bleeding duodenal ulcer in an adult patient with no evidence of other pathologies. A 18-year-old man was admitted in emergency room with gastrointestinal bleeding manifested by melena. Previous medical history revealed that he had endoscopic sclerotherapy for bleeding duodenal ulcer 5 months before. Endoscopy revealed a Forrest 2a ulcer in the duodenal bulb and sclerotherapy was performed by injecting 10 ml of 0.2% epinephrine and 20 ml of Na- Cl 0.9% solution. Upper occlusion's signs appeared 36 hours after the procedure. The hematoma, that was identified by endoscopy and confirmed by MRI and CT scan of the abdomen, caused transient duodenal obstruction. Combined conservative management with nasogastric tube and total parenteral nutrition resulted in reduction of obstructive symptoms within 4 weeks.

    In primary intracerebral hemorrhage, the presence of contrast extravasation after computed tomographic angiography (CTA), termed the spot sign, predicts hematoma expansion and mortality. Because the biological underpinnings of the spot sign are not fully understood, we investigated whether the rate of contrast extravasation, which may reflect the rate of bleeding, predicts expansion and mortality beyond the simple presence of the spot sign. Consecutive intracerebral hemorrhage patients with first-pass CTA followed by a 90-second delayed postcontrast CT (delayed CTA) were included. CTAs were reviewed for spot sign presence by 2 blinded readers. Spot sign volumes on first-pass and delayed CTA and intracerebral hemorrhage volumes were measured using semiautomated software. Extravasation rates were calculated and tested for association with hematoma expansion and mortality using uni- and multivariable logistic regressions. One hundred and sixty-two patients were included, 48 (30%) of whom had ≥1 spot sign. Median spot sign volume was 0.04 mL on first-pass CTA and 0.4 mL on delayed CTA. Median extravasation rate was 0.23 mL/min overall and 0.30 mL/min among expanders versus 0.07 mL/min in nonexpanders. Extravasation rates were also significantly higher in patients who died in hospital: 0.27 mL/min versus 0.04 mL/min. In multivariable analysis, the extravasation rate was independently associated with in-hospital mortality (odds ratio, 1.09 [95% confidence interval, 1.04-1.18], P=0.004), 90-day mortality (odds ratio, 1.15 [95% confidence interval, 1.08-1.27]; P=0.0004), and hematoma expansion (odds ratio, 1.03 [95% confidence interval, 1.01-1.08]; P=0.047). Contrast extravasation rate, or spot sign growth, further refines the ability to predict hematoma expansion and mortality. Our results support the hypothesis that the spot sign directly measures active bleeding in acute intracerebral hemorrhage. © 2015 American Heart Association, Inc.

    Varicocele is quite common in the general population, affecting up to 15% of men. It is not considered disqualifying for the pilot's training program of the Israeli Air Force as long as there are no related symptoms or associated pathologies. During combat flight, increased venous pressure due to acceleration forces and anti-G straining maneuvers, used to counteract high gravitational G forces, can theoretically aggravate the venous blood pooling in varicocele, leading to rupture. We describe a case of a young fighter-jet pilot presenting with a painful inguinal hematoma extending to the scrotum a day after participating in centrifuge training. Sonographic examination demonstrated dilated spermatic veins and intratesticular varicocele along with subcutaneous thickening of the scrotal wall consistent with hematoma. The effects of high G loads on blood flow in spermatic veins, and especially in varicocele, still need to be determined. Varicocele rupture has been described in relation to increased intra-abdominal pressure and could theoretically occur during anti-G straining maneuvers. Such an acute adverse event during combat flight can be detrimental to flight safety and the pilot's well-being.

    Acute subdural hematomas are mostly due to blunt traumatization of the head. In rare instances, subdural bleeding occurs without evidence of a previous trauma following spontaneous hemorrhage, e.g. from a ruptured aneurysm or an intracerebral hematoma perforating the brain surface and the arachnoid. The paper presents the morphological, microbiological and toxicological findings in a 38-year-old drug addict who was found by his partner in a dazed state. When brought to a hospital, he underwent trepanation to empty a right-sided subdural hematoma, but he died already 4h after admission. Autopsy revealed previously undiagnosed infective endocarditis of the aortic valve as well as multiple infarctions of brain, spleen and kidneys obviously caused by septic emboli. The subdural hematoma originated from a subcortical brain hemorrhage which had perforated into the subdural space. Microbiological investigation of the polypous vegetations adhering to the aortic valve revealed colonization by Streptococcus mitis and Klebsiella oxytoca. According to the toxicological analysis, no psychotropic substances had contributed to the lethal outcome. The case reported underlines that all deaths of drug addicts should be subjected to complete forensic autopsy, as apart from intoxications also natural and traumatic causes of death have to be taken into consideration.

Combined conservative management with nasogastric tube and total parenteral nutrition resulted in reduction of obstructive symptoms within 4 weeks. PMID:25827667

    IMPORTANCE Hematoma expansion is an important determinant of outcome in spontaneous intracerebral hemorrhage (ICH) due to small vessel disease (SVD), but the association between the severity of the underlying SVD and the extent of bleeding at the acute phase is unknown to date. OBJECTIVE To investigate the association between key magnetic resonance imaging (MRI) markers of SVD (as per the Standards for Reporting Vascular Changes on Neuroimaging [STRIVE] guidelines) and hematoma volume and expansion in patients with lobar or deep ICH. DESIGN, SETTING, AND PARTICIPANTS Analysis of data collected from 418 consecutive patients admitted with primary lobar or deep ICH to a single tertiary care medical center between January 1, 2000, and October 1, 2012. Data were analyzed on March 4, 2016. Participants were consecutive patients with computed tomographic images allowing ICH volume calculation and MRI allowing imaging markers of SVD assessment. MAIN OUTCOMES AND MEASURES The ICH volumes at baseline and within 48 hours after symptom onset were measured in 418 patients with spontaneous ICH without anticoagulant therapy, and hematoma expansion was calculated. Cerebral microbleeds, cortical superficial siderosis, and white matter hyperintensity volume were assessed on MRI. The associations between these SVD markers and ICH volume, as well as hematoma expansion, were investigated using multivariable models. RESULTS This study analyzed 254 patients with lobar ICH (mean [SD] age, 75 [11] years and 140 [55.1%] female) and 164 patients with deep ICH (mean [SD] age 67 [14] years and 71 [43.3%] female). The presence of cortical superficial siderosis was an independent variable associated with larger ICH volume in the lobar ICH group (odds ratio per quintile increase in final ICH volume, 1.49; 95% CI, 1.14–1.94; P = .004). In multivariable models, the absence of cerebral microbleeds was associated with larger ICH volume for both the lobar and deep ICH groups (odds ratios per

    To explore the effect of chronic subdural hematoma external drainage surgery using self-made "H shaped" flush type single-tube double-lumen drainage tube. There were 56 cases chosen from the First Affiliated Hospital of Bengbu Medical College between Jan 2013 and Aug 2015. These patients with unilateral chronic subdural hematoma requiring surgery to place drilling external drainage catheter were randomly divided into group A (21 cases, using self-made single-tube double lumen "H shaped" drainage tube) and group B (35 cases, traditional silicone drainage tube), then the residual liquid volume after drainage on the first day, the days that the tube stay in body and the residual fluid volume after removing the tube were compared between the two groups. The residual liquid volume after drainage on the first day in group A was (23±15)ml, in group B was (31±15)ml. The days that the tube stay in body in group A was (2.7±1.0)d, in group B was (3.3±1.1)d, the two groups had statistical differences (P<0.05). The residual fluid volume after removing the tube in group A was (13±7) ml, in group B was (16±8)ml, but the data in these two groups had no significantly statistical differences (P>0.05). The effect of self-made "H shaped" flush type single-tube double-lumen drainage tube in the drainage of chronic subdural hematoma drainage is good, with short tube stay in the body; therefore, it is a safe and effective way to treat chronic subdural hematoma, and is worthy of clinical application.

    The intracranial extradural hematoma (EDH) occupies space and creates a mass effect on the brain but the tenacious-adhesions of dura to the inner table of skull counters this effect. The intracranial pressure also pushes the hematoma back while it is held by dural tensile-force. The exploitation of a diastatic fracture, overlying an EDH, by the intracranial pressures to decompress a hematoma out of extradural space into subgaleal/subperiosteal space without surgical intervention. In a period of 15 years, a group of 11 patients among 729 EDHs were managed conservatively. The retrospective study of 11 EDH patients was conducted in the Department of Neurosurgery from January 2000 to December 2014 in 15 years. The statistical law of variance was used as applicable. Analysis of spontaneous disappearance of intracranial EDH among 11 patients revealed that only 1.5% (11/729) EDHs resolved conservatively. The most cases (63.6%) were children and the youngest being 9 months old. All the patients had a diastatic fracture overlying-EDH and were fully conscious. The cause of head injury in most was the fall from height. The hospital stay ranged from 2 to 4 days. All the patients had a good recovery at the time of discharging. The trial of the conservative or spontaneous disappearance of an EDH through a diastatic fracture into the subgaleal space is similar to burr-hole drainage without surgical intervention but depends upon the neurological status, the intracranial pressure of the patient, and the availability of all the modern neurosurgical gadgets.

    Biochemical constitution of the hematoma is depending of its evolution. In order to obtain a reliable diagnostic of the NMR images in case of vascular accidents, a systematic study of the time-evolution of hematomas has been performed, using Mössbauer spectrometry and complementary technics (ESR and visible absorption spectrophotometry). The change, in the course of time, of HbO2 in deoxyhemoglobin Hb and other denaturation products (MHb, hemi- and hemochromes,…) are well-recognized on the different spectra. T 1 and T 2 NMR relaxation times are measured in the same time and their shortening is related to the appearance of the paramagnetic denaturation blood compounds.

    Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. There is lack of uniformity in the treatment of CSDH amongst surgeons in terms of various treatment strategies. Clinical presentation may vary from no symptoms to unconsciousness. CSDH is usually diagnosed by contrast-enhanced computed tomography scan. Magnetic resonance imaging (MRI) scan is more sensitive in the diagnosis of bilateral isodense CSDH, multiple loculations, intrahematoma membranes, fresh bleeding, hemolysis, and the size of capsule. Contrast-enhanced CT or MRI could detect associated primary or metastatic dural diseases. Although definite history of trauma could be obtained in a majority of cases, some cases may be secondary to coagulation defect, intracranial hypotension, use of anticoagulants and antiplatelet drugs, etc., Recurrent bleeding, increased exudates from outer membrane, and cerebrospinal fluid entrapment have been implicated in the enlargement of CSDH. Burr-hole evacuation is the treatment of choice for an uncomplicated CSDH. Most of the recent trials favor the use of drain to reduce recurrence rate. Craniotomy and twist drill craniostomy also play a role in the management. Dural biopsy should be taken, especially in recurrence and thick outer membrane. Nonsurgical management is reserved for asymptomatic or high operative risk patients. The steroids and angiotensin converting enzyme inhibitors may also play a role in the management. Single management strategy is not appropriate for all the cases of CSDH. Better understanding of the nature of the pathology, rational selection of an ideal treatment strategy for an individual patient, and identification of the merits and limitations of different surgical techniques could help in improving the prognosis.

    Intracranial-pressure (ICP) monitoring is useful for patients with increased ICP following hemorrhagic stroke. In this study, the changes in pressure gradients between the two cerebral hemispheres were investigated after hemorrhagic stroke of one side, and after a craniotomy. Twenty-four patients with acute cerebral hemorrhages and intracerebral hematomas who exhibited mass effect and midline shift to the contralateral side on computed tomography were selected for this study. After admission, both sides of the cranium were drilled, and optical fiber sensors were implanted to monitor the brain parenchyma pressure (BPP) in both cerebral hemispheres. All patients underwent surgical hematoma evacuations. The preoperative and postoperative BPP data from both cerebral hemispheres were collected at various time points and compared pairwise. There were statistically significant differences (P < 0.01) in the preoperative BPP values between the two hemispheres at three different time points. Differences in the BPP values between the two hemispheres at the time of surgery, and 24 and 48 h after surgery, were not statistically significant (P > 0.05). The posteroperative BPPs of both hemispheres were statistically significantly lower than preoperative recordings. BPP sensors should be applied to the injured cerebral hemisphere, because this becomes the source of increased ICP. Hematoma evacuation surgery effectively decreases ICP and eliminates pressure gradients between the two cerebral hemispheres, consequently enabling brain shift correction.

    Rectus sheath hematomas (RSHs) are uncommon. They are usually unilateral and rarely bilateral. In this paper, we report the first case of spontaneous bilateral RSHs in a uremic patient after the administration of the first dose of low-molecular weight heparin during hemodialysis. The most interesting aspect of this case is that the main symptom of RSH in our patient was urinary bladder irritation. We highlight the importance of the prompt diagnosis and management of this medical emergency.

    Mycoplasma species cannot be identified by routine bacteriological culture methods and are resistant to common antimicrobial agents. Mycoplasma hominis usually colonizes the lower urogenital tract and causes pyelonephritis, pelvic inflammatory disease, chorioamnionitis, rupture of fetal membranes, preterm labor, postpartum fever, postabortal fever, and neonatal infection. This organism is highly prevalent in cervicovaginal cultures of sexually active women. M. hominis, M. genitalis, Ureaplasma urealyticum, and U. parvum may invade and infect placental and fetal tissues, leading to adverse pregnancy outcomes. M. hominis occasionally causes nongenitourinary infection of the blood, wounds, central nervous system, joints, or respiratory tract. We present a case of a 27-year-old woman who developed abdominal wound hematoma and abscess after cesarean section. The wound was drained, but her high fever persisted, in spite of antibiotic treatment using flomoxef sodium and imipenem·cilastatin sodium. Because the exudate exhibited M. hominis growth in an anaerobic environment, we administered the quinolone ciprofloxacin. This therapy resolved her fever, and her white blood cell count and C-reactive protein level diminished to the normal ranges. To our knowledge, there are four published articles regarding the isolation of M. hominis from postcesarean incisions. Based on the current study and the literature, infection by this pathogen may cause hematoma formation with or without abscess after cesarean section or in immunosuppressed postoperative patients. In such cases, physicians may need to suspect Mycoplasma infection and initiate appropriate antibacterial treatment as soon as possible in order to avoid persistent fever. PMID:21339933

    In patients undergoing cardiac device implantation, anticoagulant and antiplatelet therapy are associated with an increased risk of pocket hematoma. In case of vitamin K antagonist therapy, a strategy of continued warfarin with no heparin bridge showed a reduction of pocket hematoma. Evidence regarding antiplatelet therapy management is limited. This is a single-center observational study which reflects our systematic approach to the problem. In 2012, we proposed an improved management protocol for anticoagulant and antiplatelet therapy (no-bridge protocol) based on individual thromboembolic risk stratification, noninterruption of oral anticoagulation, no bridge with heparin and elastic adherence compression bandage. The primary end point was the incidence of clinically significant pocket hematoma in the first 30 days after implantation. A total of 1,035 patients were enrolled, of whom 522 received the standard management and 513 the new protocol. The primary end point occurred in 34 patients of the standard management group and 8 patients of the no-bridge protocol group (6.5% vs 1.6%, p <0.001). Patients in the standard management group had a higher incidence of pocket infections (2.3% vs 0.6%, p = 0.02), lead dislodgements (4.8% vs 2.1%, p = 0.02), and thromboembolic events (1.3% vs 0.0%, p <0.01). On a multivariate analysis, heparin and coronary artery disease were independent predictors of pocket hematoma (relative risk [RR] 3.48, 95% confidence interval [CI] 1.55 to 7.83 and RR 2.43, 95% CI 1.25 to 4.76, respectively), whereas the no-bridge protocol was associated with a reduction of pocket hematoma (RR 0.33, 95% CI 0.14 to 0.76). New anticoagulant and antiplatelet therapy management protocol was associated with a reduced incidence of clinically significant pocket hematomas, thromboembolic events, pocket infections, and lead dislodgements.

    Introduction Symptomatic chronic subdural hematomas (CSDH) remain one of the most frequent diagnoses in current neurosurgical practice. Burr-hole craniostomy with irrigation and placement of close-system drainage is the current recommended surgery for symptomatic CSDH. The aim of this study is to perform a direct comparison between two surgical techniques in the treatment of symptomatic CSDH, which have been proven in previous studies to be efficient. Our main objective was to compare the efficacy of placement of a subperiosteal drain (SPD) and a subdural drain (SDD) following single burr-hole craniostomy and irrigation, and to demonstrate any significant differences in terms of overall surgical complications, functional outcome at three months and mortality rate. Materials and Methods The study was carried out in two local neurosurgical centres. The SPD group was performed in Hospital Umum Sarawak (HUS) and the SDD group was performed in Hospital Sultanah Aminah Johor Bahru (HSAJB), from 1 January 2012 till 30 January 2014 with a total of 30 patients in both treatment groups. Results Overall, there were no statistically significant difference in terms of patient general characteristics, pre-operative and post-operative symptoms, Markwalder grades, post-operative hematoma volume and recurrence, mortality and functional outcome at discharge and at three month follow-up between both groups. Albeit not achieving statistical significance, we observed a lower rate of surgical complication especially for post-operative intracranial hematoma with placement of the SPD system. Conclusions Our study concludes that both treatment methods proved to be highly effective in the treatment of CSDH. However, with a lower overall surgical complication rate, treatment with single burr-hole craniostomy, irrigation and placement of the SPD system can be considered a treatment of choice for the management of symptomatic CSDH.

    The purpose of this study was to systematically determine the correlations between the post-thrombolytic changes of hemostasis parameters and the occurrence of early intracerebral hemorrhage (ICH). In 72 consecutive patients with cerebral infarcts treated with rt-PA, plasma levels of fibrinogen, plasminogen, alpha2-antiplasmin, factor XIII, fibrin(ogen) degradation products (FDPs) and d-Dimers were measured at baseline, 2 and 24h after thrombolysis. Correlations were studied between the hemostasis events and early (less than 24h) hemorrhagic infarcts (HIs) or parenchymatous hematomas (PH). Of 72 patients, 6 patients (8.3%) had early PHs, 11 (15.3%) had early HIs, and 55 (76.4%) had no bleeding. Early HIs were not linked to any hemostasis parameter at any time. Univariate comparison of patients having early PHs with non-bleeding patients showed hemostasis abnormalities at 2h: high FDP (p=0.01), high Log FDP (p=0.01), low fibrinogen (p=0.01), and low Log fibrinogen (p=0.01). Logistic regression adjusted for age, NIHSS and diabetes confirmed these 2hour predictors: Log FDP (OR: 7.50; CI: 1.26 to 44.61, p=0.03), and Log fibrinogen (OR: 19.32; CI: 1.81 to 205.98, p=0.01). The decrease in fibrinogen less than 2g/L multiplies the odds of early PH by a factor 12.82. An early fibrinogen degradation coagulopathy involving an increase of FDP and a massive consumption of circulating fibrinogen is predictive of early parenchymal hematomas, indicating the occurrence of a particularly intense lysis of circulating fibrinogen. These results, if confirmed by future studies, suggest that early assays of fibrinogen and FDP may be useful in predicting the risk of post-thrombolytic intracerebral hematoma.

    A clinical-neuropsychological study of 25 patients with hematomas, cavernomas and arteriovenous malformations of different brain stem regions has been performed. Patients with hydrocephalic-hypertensive and dislocation syndromes as well as a history of neurological diseases were excluded from the study. All patients had hemorrhages in different brain stem regions, most of which had occurred several weeks ago. Hematomas were located in different regions of the pons (14 patients) and midbrain (7 patients) and spread to both regions in 4 patients. All patients underwent MRI study of the brain and complex neuropsychological investigation using the A.R. Luria's method. Neuropsychological symptoms before the surgery were found in 20 patients. Cognitive disturbances similar by the lesion of frontal lobes, in particular the promoter zone, that manifested themselves in disturbances of dynamic praxis, writing, verbal memory, were observed most often. Cognitive disturbances similar by the lesion of occipital hemisphere regions, i.e. disturbances of visual gnosis and spatial defects, were found less often. The most severe symptoms were observed in the lesion of the midbrain and upper regions of the pons.

  14. Challenging the Pathophysiologic Connection between Subdural Hematoma, Retinal Hemorrhage and Shaken Baby Syndrome

    Gabaeff, Steven C.

    2011-01-01

    Child abuse experts use diagnostic findings of subdural hematoma and retinal hemorrhages as near-pathognomonic findings to diagnose shaken baby syndrome. This article reviews the origin of this link and casts serious doubt on the specificity of the pathophysiologic connection. The forces required to cause brain injury were derived from an experiment of high velocity impacts on monkeys, that generated forces far above those which might occur with a shaking mechanism. These forces, if present, would invariably cause neck trauma, which is conspicuously absent in most babies allegedly injured by shaking. Subdural hematoma may also be the result of common birth trauma, complicated by prenatal vitamin D deficiency, which also contributes to the appearance of long bone fractures commonly associated with child abuse. Retinal hemorrhage is a non-specific finding that occurs with many causes of increased intracranial pressure, including infection and hypoxic brain injury. The evidence challenging these connections should prompt emergency physicians and others who care for children to consider a broad differential diagnosis before settling on occult shaking as the de-facto cause. While childhood non-accidental trauma is certainly a serious problem, the wide exposure of this information may have the potential to exonerate some innocent care-givers who have been convicted, or may be accused, of child abuse.

    Vertebroplasy is considered an alternative and effective treatment of painful oncologic spine disease. Major complications are very rare, but with high morbidity and occur in less than 1% of patients who undergo vertebroplasty. Spinal subdural hematoma (SDH) is an extremely rare complication, usual developing within 12 h to 24 h after the procedure. We report the case of a tardive SDH in an oncologic patient who underwent VP for Myxoid Liposarcoma metastasis. Trying to explain the pathogenesis, we support the hypothesis that both venous congestion of the vertebral venous plexus of the vertebral body and venous congestion due to a traumatic injury can provoke SDH. To our best knowledge, only 4 cases of spinal subdural hematoma following a transpedicular vertebroplasty have been previously described in International literature and only one of them occurred two weeks after that surgical procedures. Percutaneous verteboplasty is a well-known treatment of pain oncologic spine disease, used to provide pain relief and improvement of quality life and is considered a simple surgical procedure, involving a low risk of complications, but related to high morbidity, such as SDH. Therefore it has to be performed by experienced and skilled surgeons, that should also recognize possible risk factors, making SDH more risky.

    Animal models of intracerebral hemorrhage were established by injection of autologous blood into the caudate nucleus in rats. Cell apoptosis was measured by flow cytometry and immunohistochemical staining of the p75 neurotrophin receptor. p75 neurotrophin receptor protein was detected by immunohistochemistry. p75 neurotrophin receptor mRNA was examined by quantitative real-time polymerase chain reactions. At 24 hours after modeling, cellular apoptosis occured around hematoma with upregulation of p75 neurotrophin receptor protein and mRNA was observed, which directly correlated to apoptosis. This observation indicated that p75 neurotrophin receptor upregulation was associated with cell apoptosis around hematomas after intracerebral hemorrhage.

    The occurrence of a subretinal hematoma in age-related macular degeneration (AMD) is a serious complication that can impact the visual prognosis with a poor functional recovery. The management of this complication remains controversial. Several therapeutic methods have been described. We report the results of four patients treated with a protocol combining: vitrectomy, subretinal injection of r-TPA 0.025mg/0.3ml, intravitreal injection of 0.05ml of bevacizumab and retinal tamponade with 20% SF6 gas. Our series consists of four patients with a submacular hematoma complicating AMD, included in succession between October 2013 and October 2014 and treated with the same treatment protocol and by the same surgeon. All patients underwent surgery within eight days after the onset of the macular hematoma. Patients with a consultation period longer than eight days did not undergo this treatment. Face down postoperative positioning was then carried out for seven days by the patients. We observed a shift in the macular hematoma in the four patients, which allowed the identification of secondary neovascularization responsible for the bleeding. The visual acuity improved in three patients from hand motion (HM) preoperatively to 2/10 at one month postoperatively. One patient maintained visual acuity 1/20 during the entire follow-up despite almost complete resorption of the subretinal hematoma. These visual acuities were stable at 6 months postoperatively. Macular subretinal hematoma can cause severe visual loss by several mechanisms. The blood accumulates between the neurosensory retina and the retinal pigment epithelium, which causes a toxic effect on the surrounding tissues, thus resulting in a loss of photoreceptors and cellular destruction in the pigment epithelium and choriocapillaris, evolving into a fibroglial scar. The therapeutic evaluation of this protocol in our series of four patients gives a favorable result. We observed an improvement in visual acuity in 3/4 of

    Although abdominal pain is a common presentation in emergency departments, rectus sheath hematoma (RSH) is among the rarest diagnosis. Here we present 2 cases of RSH likely caused by coughing due to upper respiratory tract infection. The two described cases were diagnosed by bedside ultrasonography and confirmed as RSH by computed tomography. Review of patient history and use of ultrasonography are important to avoid misdiagnosisof RSH.

    Motivated by the need of poor and rural Mexico, where the population has limited access to advanced medical technology and services, we have developed a new paradigm for medical diagnostic based on the technology of "Volumetric Electromagnetic Phase Shift Spectroscopy" (VEPS), as an inexpensive partial substitute to medical imaging. VEPS, can detect changes in tissue properties inside the body through non-contact, multi-frequency electromagnetic measurements from the exterior of the body, and thereby provide rapid and inexpensive diagnostics in a way that is amenable for use in economically disadvantaged parts of the world. We describe the technology and report results from a limited pilot study with 46 healthy volunteers and eight patients with CT radiology confirmed brain edema and brain hematoma. Data analysis with a non-parametric statistical Mann-Whitney U test, shows that in the frequency range of from 26 MHz to 39 MHz, VEPS can distinguish non-invasively and without contact, with a statistical significance of p<0.05, between healthy subjects and those with a medical conditions in the brain. In the frequency range of between 153 MHz to 166 MHz it can distinguish with a statistical significance of p<0.05 between subjects with brain edema and those with a hematoma in the brain. A classifier build from measurements in these two frequency ranges can provide instantaneous diagnostic of the medical condition of the brain of a patient, from a single set of measurements. While this is a small-scale pilot study, it illustrates the potential of VEPS to change the paradigm of medical diagnostic of brain injury through a VEPS classifier-based technology. Obviously substantially larger-scale studies are needed to verify and expand on the findings in this small pilot study.

    Intramural hematoma (IMH) of the thoracic aorta is a complication with unknown etiology and a poorly predictable prognosis. There is also considerable controversy about the management and prognosis of IMH as well as the treatment. We present two cases of endovascular treatment of IMH with stent-graft placement. On the basis of references, we discuss risks of progression of the given pathology and possible complications. Despite the lack of uniform opinion about the management of this disorder, we present our observations of and experiences with endovascular treatment of IMH of the thoracic aorta.

To determine if the method of assisted reproduction utilized or the use of anticoagulants, such as heparin and aspirin (ASA), influenced frequency of SCH. Prospective, cohort study. Fertility clinic and general obstetrics clinic. Five hundred and thirty-three women who were pregnant in the first-trimester. Not applicable. Frequencies of subchorionic hematomas in women based on diagnosis, use of anticoagulants, and fertility treatment. SCH were identified in 129/321 (40.2%) in the study group compared to 23/212 (10.9%) in the control group. Fertility diagnosis and the use of heparin did not appear to affect the frequency of SCH in the first trimester; however, SCH occurred at an almost four-fold increase in patients taking ASA compared to those not taking ASA, regardless of fertility diagnosis or method of fertility treatment. The use of ASA may be associated with an increased risk of developing a SCH during the first trimester. The increased frequencies of SCH in pregnancies of patients attending a fertility clinic compared to women from a general obstetrical practice was highly correlated with the use of ASA.

    Background. Previous studies showed significant interaction between the local and systemic inflammatory response after severe trauma in small animal models. The purpose of this study was to establish a new combined trauma model in pigs to investigate fracture-associated local inflammation and gain information about the early inflammatory stages after polytrauma. Material and Methods. Combined trauma consisted of tibial fracture, lung contusion, liver laceration, and controlled hemorrhage. Animals were mechanically ventilated and under ICU-monitoring for 48 h. Blood and fracture hematoma samples were collected during the time course of the study. Local and systemic levels of serum cytokines and diverse alarmins were measured by ELISA kit. Results. A statistical significant difference in the systemic serum values of IL-6 and HMGB1 was observed when compared to the sham. Moreover, there was a statistical significant difference in the serum values of the fracture hematoma of IL-6, IL-8, IL-10, and HMGB1 when compared to the systemic inflammatory response. However a decrease of local proinflammatory concentrations was observed while anti-inflammatory mediators increased. Conclusion. Our data showed a time-dependent activation of the local and systemic inflammatory response. Indeed it is the first study focusing on the local and systemic inflammatory response to multiple-trauma in a large animal model. PMID:25694748

    Right heart catheterization (RHC) is routinely performed to assess hemodynamics. Generally, anticoagulants are held prior to the procedure. At our center, anticoagulants are continued and ultrasound guidance is always used for internal jugular vein access. A micropuncture access kit is used to place a 5 or 6 Fr sheath using the modified Seldinger technique. Manual compression is applied for 10-15 min and the patient is observed for at least 2 hours after the procedure. In a retrospective analysis, we investigated the risk of bleeding complications associated with RHC via the internal jugular vein in patients with and without full anticoagulation. Our catheterization laboratory database was searched for adult patients who underwent RHC by a single operator between January 2012 and December 2015. A total of 571 patients were included in the analysis. Baseline characteristics, labs, relevant invasive hemodynamics, co-morbid conditions, and incidence of access-site hematoma are presented. Multivariable binary logistic regression was performed using IBM SPSS v. 23.0 software. Statistically significant associations with access-site hematoma were observed with body mass index (P=.02; 95% confidence interval [CI], 1.0-1.1), right atrial pressure (P=.03; 95% CI, 0.7-0.9), and dialysis dependence (P<.01; 95% CI, 0.1-0.6). There was no association of access-site hematoma with the use of anticoagulants (P>.99). The incidence of internal jugular vein access-site hematoma is small when using careful access techniques for RHC even with the continued use of novel oral anticoagulants and warfarin. Patient characteristics and co-morbid conditions are related to bleeding complications.

    The present report describes an acute subdural hematoma (ASDH) associated with subarachnoid hemorrhage (SAH), due to ruptured cortical aneurysm. To our knowledge, extremely rare cases of this sort have been reported so far. A 23-year-old male patient without previous trauma presented with severe headache and rapidly decreasing level of consciousness to decerebrate status. Computed tomography (CT) scan has demonstrated an ASDH together with SAH. Hematoma has immediately been evacuated without any evaluation by angiography. After evacuation of the thick subdural clot, a 10-mm aneurysm was revealed on a precentral artery of frontal cortex, which was ligated. However, after 35 days the patient discharged with left side hemiparesis and dysphasia, and just after several months of admission he got symptom free. Ruptured cortical aneurysm should be considered as one of the causes of spontaneous ASDH. Vascular anomaly investigations are suggested for these cases, thus CT angiography or digital subtraction angiography has to be considered if clinical condition allows. PMID:28503501

    Drepanocytic anemia is an uncommon hereditary disease in Chile. The heterozygous state of drepanocytic anemia or "sickle trait" has a frequency of 8% among Afro-Americans. A small number of patients carrying hemoglobin S are homozygous, with clinical manifestations of hemolytic anemia and thrombotic disease. Sickle trait is usually asymptomatic. We report a 59-year-old male who presented an acute abdominal pain and dyspnea while staying at high altitude. Six days later, an angio CAT scan showed the presence of a subcapsular splenic hematoma that was managed conservatively. Sickle cell induction with sodium metabisulphite was positive. Hemoglobin electrophoresis confirmed the sickle trait.

    Extravasation of iodinated contrast into subdural space following contrast-enhanced radiographic studies results in hyperdense subdural effusions, which can be mistaken as acute subdural hematomas on follow-up noncontrast head CTs. Our aim was to identify the factors associated with contrast-enhancing subdural effusion, characterize diffusion and washout kinetics of iodine in enhancing subdural effusion, and assess the utility of dual-energy CT in differentiating enhancing subdural effusion from subdural hematoma. We retrospectively analyzed follow-up head dual-energy CT studies in 423 patients with polytrauma who had undergone contrast-enhanced whole-body CT. Twenty-four patients with enhancing subdural effusion composed the study group, and 24 randomly selected patients with subdural hematoma were enrolled in the comparison group. Postprocessing with syngo.via was performed to determine the diffusion and washout kinetics of iodine. The sensitivity and specificity of dual-energy CT for the diagnosis of enhancing subdural effusion were determined with 120-kV, virtual monochromatic energy (190-keV) and virtual noncontrast images. Patients with enhancing subdural effusion were significantly older (mean, 69 years; 95% CI, 60-78 years; P < .001) and had a higher incidence of intracranial hemorrhage ( P = .001). Peak iodine concentration in enhancing subdural effusions was reached within the first 8 hours of contrast administration with a mean of 0.98 mg/mL (95% CI, 0.81-1.13 mg/mL), and complete washout was achieved at 38 hours. For the presence of a hyperdense subdural collection on 120-kV images with a loss of hyperattenuation on 190-keV and virtual noncontrast images, when considered as a true-positive for enhancing subdural effusion, the sensitivity was 100% (95% CI, 85.75%-100%) and the specificity was 91.67% (95% CI, 73%-99%). Dual-energy CT has a high sensitivity and specificity in differentiating enhancing subdural effusion from subdural hematoma. Hence, dual

    Spontaneous spinal subdural hematoma (sSDH) is a rare condition outright. Moreover, cases that occur spontaneously in the absence of an identifiable etiology are considerably less common and remain poorly understood. Here, we present the case of a 43-year-old man with spontaneous sSDH presenting with acute onset low back pain and paraplegia. Urgent magnetic resonance imaging identified a dorsal SDH from T8 to T11 with compression of the spinal cord. Emergent T8–T10 laminectomies with intradural exploration and hematoma evacuation were performed. However, despite prompt identification and appropriate action, the patient's recovery was modest and significant disability remained at discharge. This unique and unusual case demonstrates that spontaneous sSDH requires prompt surgical treatment to minimize associated morbidity and supports the association between the presence of severe neurological deficits upon initial presentation with less favorable outcomes. We performed a comprehensive systematic review of spontaneous sSDH of unknown etiology, which demonstrates that emergent surgical intervention is indicated for patients presenting with severe neurological deficits and the presence of these deficits is predictive of poor neurological outcome. Furthermore, conservative management should be considered in patients presenting with mild neurological deficits as spontaneous resolution followed by favorable neurological outcomes is often observed in these patients.

    Postoperative cervical hematoma (PCH) after thyroid and parathyroid surgery is a well-known complication. This study used data from the Nationwide Inpatient Sample to identify risk factors, estimate mortality, length of stay (LOS), and total costs attributable to PCH in patients undergoing procedures for thyroid and parathyroid diseases. Patients aged >18 y who underwent thyroid or parathyroid surgery between 2001 and 2011 were identified and stratified by the occurrence of PCH. Univariate analyses of patient demographics, clinical and hospital characteristics were performed. Multivariable logistic regression was used to determine risk factors for hematoma formation. LOS and costs were fit to linear regression models to determine the effect of PCH after adjusting for patient and hospital characteristics. Of patients who underwent thyroid or parathyroid surgery, 619 patients (0.8%) had a PCH. Predisposing factors included nonelective admission (emergent: OR = 2.01, P < 0.0001; urgent: OR = 1.47, P = 0.003), diagnosis of Graves' disease (OR = 1.90, P < 0.0001), or other benign pathology (OR = 1.43, P = 0.011) and having ≥2 comorbidities (2-3 comorbidities, OR = 1.24; P = 0.036 and ≥ 4 comorbidities, OR = 2.28; P < 0.0001). After adjusting for those characteristics, the total excess LOS and costs attributable to PCH were 2.1 d (P < 0.0001) and $7316 (P < 0.0001), respectively. In addition, after risk adjustment, odds of mortality more than tripled (P < 0.0001) in the setting of PCH. Because risk for PCH is largely driven by preoperative patient risk factors, five clinicians have an opportunity to stratify patients accordingly and thereby minimize the resource utilization and health care spending among those with lowest risk.

    Background: Chronic subdural hematoma (CSDH) is a commonly encountered condition in neurosurgical practice. In Nigeria, a developing country, patients with CSDH are less likely to be diagnosed and treated by surgical drainage early. Aware of the reported variations in neurosurgeons’ practices regarding CSDH in many parts of the world, we sought to determine the current practices of Nigerian neurosurgeons in managing CSDH. Methods: An Internet-based survey was carried out in which all Nigerian neurosurgeons listed in the Nigerian Academy of Neurological Surgeons directory during the July–December 2012 time period were asked to participate. Questions asked in the survey were: (1) Type of treatment used in patients with CSDH, (2) Use of drains postoperatively, (3) Postoperative patient positioning, (4) Postoperative mobilization, (5) Postoperative complications, and (6) Postoperative computed tomography (CT) scan monitoring. Results: Survey information was sent to the 25 practicing neurosurgeons in Nigeria who met the criteria listed above for being included in this study. Each of the 14 neurosurgeons who responded reported that CSDH is often misdiagnosed initially, usually as a stroke having occurred. Once a diagnosis of CSDH was made, the most common method of treatment reported was placement of one or two burr-holes for drainage of the hematoma. Reported, but used in only a few cases, were twist drill craniostomy, craniectomy, and craniotomy. Each neurosurgeon who responded reported irrigation of the subdural space with sterile saline, and in some cases an antibiotic had been added to the irrigation solution. Six of the 14 neurosurgeons left drains in the subdural space for 24-72 hours. Seven neurosurgeons reported positioning patients with their heads elevated 30° during the immediate postoperative period.

    An objective of the study was to compare sensitivity of low- and extra high-field frequency magnetic resonance (MR) tomography of acutest intracerebral hematomas (ICH) and to assess differences between symptoms in obtained images. A study was conducted using experimental ICH in rats (n=6). Hematomas were formed by two injections of autologic blood into the brain. MR-devices "Bio Spec 70/30" with magnetic field strength of 7 T and "Ellipse-150" with magnetic field strength of 0,15 T were used in the study. MR-tomography was carried out 3-5 h after the injections. Both MR-devices revealed the presence of pathological lesion in all animals. Extra highfield frequency MR-tomography showed the specific signs of ICH caused by the paramagnetic effect of deoxyhemoglobin in T2 and T2*-weighted images (WI) and low frequency MR-tomography - in T2*-WI only. The comparable sensitivity of low- and extra high-field frequency MR-devices in acutest ICH was established.

    Objective To evaluate the predictive value of the symptoms of an intrauterine hematoma (IUH) for adverse pregnancy outcomes. Methods A literature review was performed with the search terms, including intrauterine/subchorionic/retroplacental/subplacental hematoma/hemorrhage/bleeding/collection/fluid, covering the period from January, 1981 to January, 2014. We just focused on the pregnancy outcomes associated with different symptoms of an IUH. Results It is generally agreed that a retroplacental, posterior or subchorionic in the fundus of uterus, and/or persistent IUH is associated with adverse outcomes in the ongoing pregnancy. However, the prognosis value of both volume and gestational age at diagnosis of IUH still remains controversial. Some researchers argue that a large IUH is associated with an increased risk of adverse events during pregnancy while others refuted. It is believed by some that the earlier an IUH was detected, the higher the risk for adverse outcomes would be, while no or weak association were reported by other studies. The prognostic value of the simultaneous presence of vaginal bleeding on pregnancy outcome is also controversial. Conclusions Both the position relative to the placenta or uterus and duration of IUH have strong predictive value on the prognosis in the ongoing pregnancy. However, the prognostic values of the IUH volume, gestational age at diagnosis and the simultaneous presence of vaginal bleeding remain controversial up to now. Moreover, most of previous reports are small, uncontrolled studies with incomplete information. Prospective, large sample, cohorts studies which take all detailed symptoms of an IUH into consideration are needed when we evaluate its clinical significance in the prognosis of pregnancy.

    This study aimed at identifying the determinants and prognostic significance of a sedimentation level (fluid-blood level) in the hematoma among patients with acute intracerebral hemorrhage (ICH) who participated in the main Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2). Post-hoc analysis of the INTERACT2 dataset, a randomized controlled trial of patients with acute ICH with elevated systolic blood pressure (SBP), randomly assigned to intensive (target SBP <140 mm Hg) or guideline-based (<180 mm Hg) BP management. Patients with a sedimentation level at baseline assessment on CT, and modified Rankin Scale score at 90-day, were included in these analyses. Factors associated with a sedimentation level and its significance in relation to 90-day clinical outcomes were assessed in univariable and multivariable logistic regression models. Of 2,065 participants, 19 (1%) had sedimentation level on baseline CT, which was independently associated with warfarin use (p = 0.006) and lobar ICH (p = 0.025). Sedimentation level was also associated with death or major disability at 90-day in both crude (84 vs. 53%; p = 0.014) and multivariable analyses adjusted for age, gender, Chinese region, warfarin use, baseline National Institutes of Health Stroke Scale score, onset to CT time, volume and location of ICH, intraventricular extension, and randomized intensive BP lowering (OR 3.94, 95% CI 1.01-15.37; p = 0.049). The presence of hematoma sedimentation level on baseline CT is associated with warfarin use and lobar location of ICH, and predicts a worse outcome. Although uncommon, sedimentation level is an easily detectable prognostic factor in acute ICH. © 2015 S. Karger AG, Basel.

    Hemorrhagic conversion of spinal schwannomas represents a rare occurrence; also rare is the development of a spinal intradural hematoma after spinal manipulation therapy. We report a unique presentation of paraplegia in a patient who underwent spinal manipulation therapy and was found to have a hemorrhagic thoracic schwannoma at time of surgery in the setting of anti-platelet therapy use. In patients with spinal schwannomas, tumor hemorrhage is a rare occasion, which can be considered in the setting of additive effects of spinal manipulation therapy and antiplatelet therapy.

    Trephination or trepanation is an intentional surgical procedure performed from the Stone Age. It looks like escaping a black evil from the head. This technique is still used for treatment of chronic subdural hematoma (SDH). Now, we know the origin, pathogenesis and natural history of this lesion. The author try to explore the history of trephination and modern discovery of chronic SDH. The author performed a detailed electronic search of PubMed. By the key word of chronic SDH, 2,593 articles were found without language restriction in May 2015. The author reviewed the fact and way, discovering the present knowledge on the chronic SDH. The first authentic report of chronic SDH was that of Wepfer in 1657. Chronic SDH was regarded as a stroke in 17th century. It was changed as an inflammatory disease in 19th century by Virchow, and became a traumatic lesion in 20th century. However, trauma is not necessary in many cases of chronic SDHs. The more important prerequisite is sufficient potential subdural space, degeneration of the brain. Modifying Virchow's description, chronic SDH is sometimes traumatic, but most often caused by severe degeneration of the brain. From Wepfer's first description, nearly 350 years passed to explore the origin, pathogenesis, and fate of chronic SDH. The nature of the black evil in the head of the Stone Age is uncovering by many authors riding the giant's shoulder. Chronic SDH should be categorized as a degenerative lesion instead of a traumatic lesion. PMID:27169062

    A controlled local inflammatory response is essential for adequate fracture healing. However, the current literature suggests that local and systemic hyper-inflammatory conditions after major trauma induce increased influx of neutrophils into the fracture hematoma (FH) and impair bone regeneration. Inhibiting neutrophil chemotaxis towards the FH without compromising the hosts' defense may therefore be a target of future therapies that prevent impairment of fracture healing after major trauma. We investigated whether chemotaxis of neutrophils towards the FH could be studied in vitro. Moreover, we determined whether chemotaxis of neutrophils towards the FH was mediated by the CXCR1, CXCR2, FPR, and C5aR receptors. Human FHs were isolated during an open reduction internal fixation (ORIF) procedure within 3 days after trauma and spun down to obtain the fracture hematoma serum. Neutrophil migration towards the FH was studied using Ibidi™ Chemotaxis 3D μ-Slides and image analysis of individual neutrophil tracks was performed. Our study showed that the human FH induces significant neutrophil chemotaxis, which was not affected by blocking CXCR1 and CXCR2. In contrast, neutrophil chemotaxis towards the FH was significantly inhibited by chemotaxis inhibitory protein of Staphylococcus aureus (CHIPS), which blocks FPR and C5aR. Blocking only C5aR with CHIPSΔ1F also significantly inhibited neutrophil chemotaxis towards the FH. Our finding that neutrophil chemotaxis towards the human FH can be blocked in vitro using CHIPS may aid the development of therapies that prevent impairment of fracture healing after major trauma.

    The present study examined the computed tomography (CT) findings after surgery and overnight drainage for chronic subdural hematoma (CSDH) to clear the significance of inner superficial subarachnoid CSF space and outer subdural hematoma cavity between the brain surface and the inner skull. A total of 73 sides in 60 patients were evaluated. Head CT was performed on the day after surgery and overnight drainage (1st CT), within 3 weeks of surgery (2nd CT), and more than 3 weeks after surgery (3rd CT). Subdural and subarachnoid spaces were identified to focus on density of fluid, shape of air collection, and location of silicone drainage tube, etc. Cases with subdural space larger than the subarachnoid CSF space were classified as Group SD between the brain and the skull. Cases with subarachnoid CSF space larger than the subdural space were classified as Group SA. Cases with extremely thin (<3 mm) spaces between the brain and the skull were classified as Group NS. Group SA, SD, and NS accounted for 31.9, 55.6 and 12.5% of cases on the 1st CT. No statistical differences were found between Groups SA, SD, and NS in any clinical factors, including recurrence. Group SA were found significantly more on 1st CT than on 2nd and 3rd CT. Subarachnoid CSF space sometimes expands between the brain and skull on CT after surgical overnight drainage. Expansion of the arachnoid space may be a passive phenomenon induced by overnight drainage and delayed re-expansion of the brain parenchyma.

    Treatments for major internal bleeding after injury include permissive hypotension to decrease the rate of blood loss, intravenous infusion of plasma or clotting factors to improve clot formation, and rapid surgical hemostasis or arterial embolization to control bleeding vessels. Yet, little is known regarding major internal arterial hemostasis, or how these commonly used treatments might influence hemostasis. (i) To use a swine model of femoral artery bleeding to understand the perivascular hemostatic response to contained arterial hemorrhage. (ii) To directly confirm the association between hemodynamics and bleeding velocity. (iii) To observe the feasibility of delivering an activated clotting factor directly to internal sites of bleeding using a simplified angiographic approach. Ultrasound was used to measure bleeding velocity and in vivo clot formation by elastography in a swine model of contained femoral artery bleeding with fluid resuscitation. A swine model of internal pelvic and axillary artery hemorrhage was also used to demonstrate the feasibility of local delivery of an activated clotting factor. In this model, clots formed slowly within the peri-wound hematoma, but eventually contained the bleeding. Central hemodynamics correlated positively with bleeding velocity. Infusion of recombinant human activated factor VII into the injured artery near the site of major internal hemorrhage in the pelvis and axillae was feasible. We rediscovered that clot formation within the peri-wound hematoma is an integral component of hemostasis and a feasible target for the treatment of major internal bleeding using activated clotting factors delivered using a simplified angiographic approach. © 2015 International Society on Thrombosis and Haemostasis.

    Little is known about the natural history of non-surgically managed subdural hematoma (SDH). The purpose of this study is to determine rates of adverse events after non-surgical management of SDH and whether these outcomes differ depending on traumatic versus nontraumatic etiology. A retrospective cohort study was conducted using administrative claims data on all emergency department visits and acute care hospitalizations at nonfederal facilities in California from 2005 to 2011, Florida from 2005 to 2012, and New York from 2006 to 2011. We included patients who were discharged home after hospitalization with a first-recorded diagnosis of SDH and no record of surgical hematoma evacuation. Patients were followed for readmission with SDH, readmission for surgical SDH evacuation, and fatal readmission with SDH. Survival statistics and the log-rank test were used to compare rates of these adverse events after traumatic versus nontraumatic SDH. Multivariable Cox regression analysis was used to compare hazards for traumatic versus nontraumatic etiology while adjusting for age, sex, race, insurance status, presence of dementia, alcohol use, acquired abnormalities in coagulation, acquired abnormalities in platelet function, hypertension, atrial fibrillation, venous thromboembolism, ischemic stroke, coronary heart disease, and valvular disease. We identified 27,502 conservatively treated patients with SDH, of which 70.9% were traumatic and 29.1% nontraumatic. Compared to patients with traumatic SDH, patients with nontraumatic SDH had significantly higher rates of subsequent hospitalization with SDH (cumulative 90-day rates: 15.3 % [95% CI 14.5-16.1%] vs. 10.3% [95% CI 9.9-10.8%]), surgical SDH evacuation (7.8% [95% CI 7.3-8.5%] vs. 5.5% [95% CI 5.2-5.8%]), and SDH-related in-hospital death (1.0% [95% CI 0.8-1.2%] vs. 0.4% [95 % CI 0.3-0.5%]). In multivariable Cox regression analysis, nontraumatic etiology was associated with a higher hazard of readmission with SDH (HR 1

    Introduction. In acute stroke by occlusion of the proximal medial cerebral artery (MCA) or the distal internal carotid artery, intravenous thrombolysis is an established treatment. Another option is mechanical recanalization. It remains unclear if the combination of both methods poses an additional bleeding risk. The aim of this retrospective analysis is to determine the proportion of hemorrhagic infarctions and parenchymal hematomas. Methods. Inclusion criteria were an occlusion of the carotid T or proximal MCA treated with full dose thrombolysis and mechanical recanalization. 31 patients were selected. Devices used were Trevo, Penumbra Aspiration system, Penumbra 3D Retriever, and Revive. The initial control by computed tomography was carried out with a mean delay to intervention of 10.9 hours (SD: 8.5 hours). Results. A slight hemorrhagic infarction (HI1) was observed in 2/31 patients, and a more severe HI2 occurred in two cases. A smaller parenchymal hematoma (PH1) was not seen and a space-occupying PH2 was seen in 2/31 cases. There was no significant difference in the probability of intracranial bleeding after successful (thrombolysis in cerebral infarctions 2b and 3) or unsuccessful recanalization. Conclusion. The proportion of intracranial bleeding using mechanical recanalization following intravenous thrombolysis appears comparable with reports using thrombolysis alone. PMID:26640710

    Chronic expanding hematoma (CEH) is a rare disease that is usually present as a large solitary pulmonary nodule. CEHs are slow growing, but processes underlying their development remain unknown. The present study herein reports the case of a 76-year-old male patient with CEH and discusses a number of CEH cases published in the literature. The majority of these previously described patients were Asians. The CEH in the present case was not a successfully resected one, but the patient's clinical course provided information concerning the natural history of the disease. During the clinical course, the patient underwent several chest computed tomography scans. For the present case report, the doubling time and volume change of the mass was calculated, which revealed that the lesion had an inconstant growth rate and that its onset was between 8.2-11.0 years before the patient succumbed to this disease. Accumulation of knowledge about this rare disease will help to elucidate it further.

Application of the classification proposed permits to formulate diagnosis and to choose the tactic of treatment correctly. The intraoperative tactics algorithm was elaborated. It promotes the correct analysis of intraoperative findings and reduction of the diagnostic mistakes frequency as well. In the presence of vast defect, making impossible to suture over the parietal peritoneum, extraperitonization using cerebral dura mater was done. Operative intervention was concluded by drainage with subsequent laserotherapy.

    Spontaneous splenic rupture (SSR) is a rare but potentially lethal complication of infectious mononucleosis (IM). Because the inflamed spleen is usually enlarged, congested, and friable, emergency splenectomy is recommended. We describe the conservative management of a SSR in a 16-year-old boy with IM. A pigtail catheter was inserted under ultrasonographic guidance and left in place for 36 h. This allowed the successful evacuation of the hematoma without compromising the splenic parenchyma.

    Neurological manifestations in dengue fever occur in <1 % of the patients and known to be due to multisystem dysfunction secondary to vascular leakage. Occurrence of wide spread cerebral haemorrhages with subdural hematoma during the leakage phase without profound thrombocytopenia and occurrence of cranial diabetes insipidus are extremely rare and had not been reported in published literature earlier, thus we report the first case. A 24 year old previously healthy lady was admitted on third day of fever with thrombocytopenia. Critical phase started on fifth day with evidence of pleural effusion and moderate ascites. Thirty one hours into critical phase she developed headache, altered level of consciousness, limb rigidity and respiratory depression without definite seizures. Non-contrast CT brain done at tertiary care level revealed diffuse intracranial haemorrhages and sub arachnoid haemorrhages in right frontal, parietal, occipital lobes and brainstem, cerebral oedema with an acute subdural hematoma in right temporo- parietal region. Her platelet count was 40,000 at this time with signs of vascular leakage. She was intubated and ventilated with supportive care. Later on she developed features of cranial diabetes insipidus and it responded to intranasal desmopressin therapy. In spite of above measures signs of brainstem herniation developed and she succumbed to the illness on day 8. Dengue was confirmed serologically. Exact pathophysiological mechanism of diffuse cerebral haemorrhages without profound thrombocytopenia is not well understood. Increased awareness and high degree of clinical suspicion is needed among clinicians for timely diagnosis of this extremely rare complication of dengue fever. We postulate that immunological mechanisms may play a role in pathogenesis. However further comprehensive research and studies are needed to understand the pathophysiological mechanisms leading to this complication.

    Fibrin membranes and compartmentalization within the subdural space are a frequent cause of failure in the treatment of chronic subdural hematomas (CSH). This specific subtype of CSH classically requires craniotomy, which carries significant morbidity and mortality rates, particularly in elderly patients. In this work, we describe a minimally invasive endoscopic alternative. Under local scalp anesthesia, a rigid endoscope is inserted through a parietal burr hole in the subdural space to collapse fibrin septa and cut the internal membrane. It also allows cauterization of active bleedings and the placement of a drain under direct visualization. The endoscopic treatment of septated CSH represents a minimally invasive alternative to craniotomy especially for the internal membranectomy.

    Background: A chronic subdural hematoma is an old clot of blood on the surface of the brain between dura and arachnoid membranes. These liquefied clots most often occur in patients aged 60 and older with brain atrophy. When the brain shrinks inside the skull over time, minor head trauma can cause tearing of blood vessels over the brain surface, resulting in a slow accumulation of blood over several days to weeks. Aim of the Study: To evaluate the role of membrane in hematoma evaluation and to correlate its histopathology with clinic-radiological aspects of the condition and overall prognosis of patients. Material and Methods: The study incorporated all cases of chronic SDH admitted to the Neurosurgery department of JLN Hospital and Research Centre, Bhilai, between November 2011 and November 2013. All such cases were analyzed clinically, radiologically like site, size, thickness in computed tomography, the attenuation value, midline shift and histopathological features were recorded. Criteria for Inclusion: All cases of chronic subdural haematoma irrespective of age and sex were incorporated into the study. Criteria for Exclusion: All cases of acute subdural haematoma and cases of chronic sub dural hematoma which were managed conservatively irrespective of age and sex were excluded from the study Results: In our series of cases, the most common histopathological type of membrane was the inflammatory membrane (Type II) seen in 42.30% of cases followed by hemorrhagic inflammatory membrane (Type III) seen in 34.62% of cases while scar inflammatory type of membrane (Type IV) was seen in 23.08% of cases. No case with noninflammatory type (Type I) was encountered. PMID:26889276

    Blunt force injuries in martial arts occur frequently but isolated hematoma of muscles in the extremities is rare. Even minor trauma of the lower extremities due to throwing techniques in judo and other forms of Asian martial arts can lead to major pathologies. A 9-year-old girl presented with an unclear swelling and soreness of the calf muscle. The patient could not remember an obvious traumatic event. She was admitted 4 days later because of increased swelling, pain and erythema. The parents reported a minor trauma at judo training 1 week ago. Further investigation was performed with MRI and confirmed a massive hematoma much greater than previously shown by sonography. Histologic and microbiologic evaluation demonstrated florid inflammation and proof of Staphylococcus aureus was found intra-operatively. The diagnosis of blunt force injuries due to martial arts is difficult in childhood because often children do not remember a traumatic event. Therefore, it is important to obtain a thorough history from caregivers. Because sonography depends highly on the experience of the investigator MRI is considered to be a better diagnostic modality to diagnose and guide treatment in this age group.

    The etiology of chronic subdural hematoma (CSDH) in nongeriatric patients (≤ 60 years old) often remains unclear. The primary objective of this study was to identify spinal CSF leaks in young patients, after formulating the hypothesis that spinal CSF leaks are causally related to CSDH. All consecutive patients 60 years of age or younger who underwent operations for CSDH between September 2009 and April 2011 at Bern University Hospital were included in this prospective cohort study. The patient workup included an extended search for a spinal CSF leak using a systematic algorithm: MRI of the spinal axis with or without intrathecal contrast application, myelography/fluoroscopy, and postmyelography CT. Spinal pathologies were classified according to direct proof of CSF outflow from the intrathecal to the extrathecal space, presence of extrathecal fluid accumulation, presence of spinal meningeal cysts, or no pathological findings. The primary outcome was proof of a CSF leak. Twenty-seven patients, with a mean age of 49.6 ± 9.2 years, underwent operations for CSDH. Hematomas were unilateral in 20 patients and bilateral in 7 patients. In 7 (25.9%) of 27 patients, spinal CSF leakage was proven, in 9 patients (33.3%) spinal meningeal cysts in the cervicothoracic region were found, and 3 patients (11.1%) had spinal cysts in the sacral region. The remaining 8 patients (29.6%) showed no pathological findings. The direct proof of spinal CSF leakage in 25.9% of patients suggests that spinal CSF leaks may be a frequent cause of nongeriatric CSDH.

    Whether surgery improves the outcome more than medical management alone continues to be a subject of intense debate and controversy. However, there is optimism that the management of spontaneous supratentorial intracerebral haemorrhage will change in future based new insight and better understanding of the acute pathophysiology of hematomas and its dynamics. Craniotomy as a surgical approach has been the most studied intervention for spontaneous supratentorial intracerebral haemorrhage but with no significant benefit when compared to best medical management. A literature search was conducted using electronic data bases including the Cochrane Central Register of Controlled Trials (CENTRAL) on the Cochrane library, MEDLINE and EMBASE. In addition, critical appraisal of most current evidences was carried out. About 1387 articles identified through database search over 10-year period of which one systematic review and two randomised controlled trials most relevant to this review were critically appraised. The role of surgery in the management of spontaneous intracerebral haemorrhage still remains a matter of debate. There is insufficient evidence to justify a general policy of early surgery for patients with spontaneous intracerebral haemorrhage compared to initial medical management but STICH did demonstrate that patients with superficial hematoma might benefit from craniotomy.

    Manually segmented traumatic pelvic hematoma volumes are strongly predictive of active bleeding at conventional angiography, but the method is time intensive, limiting its clinical applicability. We compared volumetric analysis using semi-automated region growing segmentation to manual segmentation and diameter-based size estimates in patients with pelvic hematomas after blunt pelvic trauma. A 14-patient cohort was selected in an anonymous randomized fashion from a dataset of patients with pelvic binders at MDCT, collected retrospectively as part of a HIPAA-compliant IRB-approved study from January 2008 to December 2013. To evaluate intermethod differences, one reader (R1) performed three volume measurements using the manual technique and three volume measurements using the semi-automated technique. To evaluate interobserver differences for semi-automated segmentation, a second reader (R2) performed three semi-automated measurements. One-way analysis of variance was used to compare differences in mean volumes. Time effort was also compared. Correlation between the two methods as well as two shorthand appraisals (greatest diameter, and the ABC/2 method for estimating ellipsoid volumes) was assessed with Spearman's rho (r). Intraobserver variability was lower for semi-automated compared to manual segmentation, with standard deviations ranging between ±5-32 mL and ±17-84 mL, respectively (p = 0.0003). There was no significant difference in mean volumes between the two readers' semi-automated measurements (p = 0.83); however, means were lower for the semi-automated compared with the manual technique (manual: mean and SD 309.6 ± 139 mL; R1 semi-auto: 229.6 ± 88.2 mL, p = 0.004; R2 semi-auto: 243.79 ± 99.7 mL, p = 0.021). Despite differences in means, the correlation between the two methods was very strong and highly significant (r = 0.91, p < 0.001). Correlations with diameter-based methods were only moderate and nonsignificant. Mean semi

    Marfan syndrome is a connective tissue disorder affecting many structures, including the skeleton, lungs, eyes, heart and blood vessels. It is an autosomal dominant inherited disorder due to a mutation of a gene encoding fibrillin-1, which affects connective tissue. Few case reports have associated Marfan syndrome with vascular malformations of the brain and spinal cord. In this regard, association with intracranial aneurysm has been vaguely proposed. We report here a patient with Marfan syndrome who was admitted because of a sudden loss of consciousness. The patient underwent computed tomography (CT) examination, which disclosed a right intracerebellar hematoma. Cerebral angiogram did not demonstrate aneurysm or arteriovenous malformation (AVM), or evidence of any other vascular lesions or neoplasms in the posterior fossa. Conservative treatment was undertaken. The clinical course was uneventful and after 6 weeks the patient was discharged free of symptoms. Although patients with Marfan syndrome are at high risk of vascular abnormalities, a clear association with cerebral aneurysm has not yet been established. Our experience and the contrasting reports available in the medical literature strongly warrant further studies in order to better clarify this controversial association.

    We aimed to characterize the occurrence of postoperative hematoma (POH) after neurosurgery overall and according to procedure type and describe the prevalence of possible confounders. Patient data between 2010 and 2012 at the Department of Neurosurgery in Helsinki University Hospital were retrospectively analyzed. A data search was performed according to the type of surgery including craniotomies; shunt procedures, spine surgery, and spinal cord stimulator implantation. We analyzed basic preoperative characteristics, as well as data about the initial intervention, perioperative period, revision operation and neurologic recovery (after craniotomy only). The overall incidence of POH requiring reoperation was 0.6% (n = 56/8783) to 0.6% (n = 26/4726) after craniotomy, 0% (n = 0/928) after shunting procedure, 1.1% (n = 30/2870) after spine surgery, and 0% (n = 0/259) after implantation of a spinal cord stimulator. Craniotomy types with higher POH incidence were decompressive craniectomy (7.9%, n = 7/89), cranioplasty (3.6%, n = 4/112), bypass surgery (1.7%, n = 1/60), and epidural hematoma evacuation (1.6%, n = 1/64). After spinal surgery, POH was observed in 1.1% of cervical and 2.1% of thoracolumbar operations, whereas 46.7% were multilevel procedures. 64.3% of patients with POH and 84.6% of patients undergoing craniotomy had postoperative hypertension (systolic blood pressure >160 mm Hg or lower if indicated). Poor outcome (Glasgow Outcome Scale score 1-3), whereas death at 6 months after craniotomy was detected in 40.9% and 21.7%. respectively, of patients with POH who underwent craniotomy. POH after neurosurgery was rare in this series but was associated with poor outcome. Identification of risk factors of bleeding, and avoiding them, if possible, might decrease the incidence of POH.

    Purpose Although several strategies against recurrent chronic subdural hematoma (CSDH) have been proposed, no consensus has been established. Recently, middle meningeal artery (MMA) embolization has been proposed as radical treatment for recurrent CSDH. We wanted to estimate the usefulness of MMA embolization for recurrent CSDH. Methods From February 2012 to June 2013, 110 patients with CSDH underwent single burr-hole surgery with irrigation and drainage. Among these patients, 13 showed recurrent hematoma formation and were retreated surgically. Furthermore, repeated recurrence of CSDH was observed in six patients. Five of these six patients underwent middle meningeal artery (MMA) embolization with polyvinyl alcohol particles. All five patients with interventional treatment were observed for four to 60 weeks. Results No more recurrence of CSDH was observed in any of the patients. During the follow-up period, no patients suffered from any side effects or complications from the interventional treatment. Conclusion MMA embolization with careful attention paid to the procedure might be a treatment of choice for recurrent CSDH. PMID:26015518

    Calcified chronic subdural hematomas are an occurrence rarely seen in neurosurgical clinical practice. And when they occur bilaterally, the radiologic image they present is fascinating, as is the clinical presentation, but their management may be challenging. They have been reported to present with a multitude of neurologic deficits but never with diabetes insipidus, which is described here. Due to the rarity of this pathology, the management protocol is not well defined, though there have been quite a few papers on this condition. This review article gathers information published over the years on this rare entity to suggest a treatment protocol. Copyright © 2016 Elsevier Inc. All rights reserved.

    Context Acute hemiparesis is a common initial presentation of ischemic stroke. Although hemiparesis due to spontaneous spinal epidural hematoma (SSEH) is an uncommon symptom, a few cases have been reported and misdiagnosed as cerebral infarction. Design Case reports of SSEH with acute hemiparesis. Findings In these two cases, acute stroke was suspected initially and administration of intravenous alteplase therapy was considered. In one case, the presentation was neck pain and in the other case, it was Lhermitte's sign; brain magnetic resonance imaging (MRI) and magnetic resonance angiography were negative for signs of ischemic infarction, hemorrhage, or arterial dissection. Cervical MRI was performed and demonstrated SSEH. Conclusion Clinicians who perform intravenous thrombolytic treatment with alteplase need to be aware of this possible contraindication.

    This prospective study was designed to analyze the dependence of different factors on the recurrence rate of chronic subdural hematoma (cSDH) after surgical treatment. Seventy-three consecutive patients, who were surgically treated at our department due to cSDH between 2009 and 2012, were included. The following parameters were analyzed: patient age and gender, occurrence of trauma, time between trauma and admission, neurological symptoms, presence of minor diseases, intake of anticoagulation medication. We classified the results of diagnostic imaging and determined the space-consuming effect via the cerebral midline shift. In addition, we scrutinized intraoperative findings and the dependence of the position of subdural drainage on the recurrence rate of cSDH. In our patient group, cSDH recurrence was significantly associated with aphasia (p=0.008). Moreover an increased cSDH recurrence rate was observed in the patient group that had a separated manifestation of the cSDH in the preoperative diagnostic imaging (p=0.048) and received no drainage implant (p=0.016). Homogeneous isodense cSDH was associated with no apparent recurrence (p=0.037). Within the scope of this study, we detected aphasia and separated cSDH as predictors of cSDH recurrence. Homogeneous isodense cSDH seems to be a good prognostic sign regarding the risk of recurrence development. Furthermore, our data clearly emphasize the importance of surgically applied drainage implants to prevent a recurrence of cSDH.

    Relatively frequent pituitary hormone deficiencies are observed after traumatic brain injury (TBI) and subarachnoid hemorrhage (SAH) and according to the published studies the neuroendocrine consequenses of traumatic brain injury are underdiagnosed. In a cohort of 59 patients (49 males, mean age 68.3 years, 36-88 years) after evacuation of subdural hematoma (SDH) were evaluated hypothalamo-pituitary functions one week after surgery, after three months and after one year. Hypogonadism was present in 26 % of patients in an acute phase, but in the majority had a transient character. Less than half of patients was GH deficient (GHD) according to the GHRH+arginine test. We did not find any serious case of hypocortisolism, hypothyroidism, diabetes insipidus centralis nor syndrome of inappropriate secretion of ADH (SIADH). Transient partial hypocortisolism was present in two cases, but resolved. We did not find relation between extension of SDH or clinical severity and development of hypopituitarism. In conclusion, in some patients with SDH growth hormone deficiency or hypogonadism was present. No serious hypocortisolism, hypothyroidism, diabetes insipidus nor SIADH was observed. The possibility of neuroendocrine dysfunction should be considered in patients with SDH, although the deficits are less frequent than in patients after TBI or SAH.

    Rectus sheath hematoma (RSH) is a rare clinical entity. It can be mistaken for other intra-abdominal disorders, which can result in diagnostic and therapeutic difficulties. This study was undertaken to analyze the clinical presentation, diagnostic modalities, and management of patients affected with RSH. Between January 2008 and June 2011, eight patients (5 men and 3 women with a mean age of 53 years) with RSH were evaluated according to demographic characteristics, clinical and radiological findings, and methods of treatment. Six patients developed RSH after anticoagulant therapy; one after local trauma, and one after laparoscopic intervention. Six patients were treated nonsurgically; one patient underwent embolization of the inferior epigastric artery and one underwent ligation of the bleeding vessel. The average hospital stay was 6 days. There were no mortality or thromboembolic complications. RSH is a rare nonneoplastic entity that is usually associated with abdominal trauma and/or anticoagulant therapy. The gold standard for diagnosis is computed tomography, and ultrasonography can be used in follow-up. The treatment of choice is nonsurgical therapy because RSH is a self-limited condition. Surgical intervention should be reserved for cases with hemodynamic instability. Copyright © 2013. Published by Elsevier B.V.

    Rapid spontaneous resolution of posttraumatic intracranial ASDH has been reported in the literature since 1986. We report a case to demonstrate that redistribution of hematoma to the spinal subdural space is a mechanism for the rapid spontaneous resolution of posttraumatic intracranial ASDH. A 73-year-old woman with a slipped-and-fell injury had a worst GCS score of 8/15. Computerized tomography of the brain demonstrated a large intracranial ASDH with mass effect. Conservative management was decided because of her poor premorbid general condition. Rapid clinical improvement was observed within 5 hours after the CT. Progress CT of the brain at 45 hours postinjury showed that the size of the intracranial ASDH was markedly diminished. The CT findings apparently demonstrated a caudal distribution of the intracranial ASDH over the tentorium and then into the posterior fossa. To investigate this further, an MRI of the spine was performed, which showed that there was spinal SDH in the cervical and thoracic spine. This is the first report demonstrating that redistribution of posttraumatic intracranial ASDH to the spinal subdural space is one of the mechanisms behind the rapid spontaneous resolution of posttraumatic intracranial ASDH in the acute phase.

    Antiplatelet therapy in patients with chronic subdural hematoma (cSDH) presents significant neurosurgical challenges. Given the lack of guidelines regarding perioperative management with antiplatelet therapy, it is difficult to balance the patient's increased cardiovascular risk and prevalence of cSDH. To better understand the risk and recurrence rates related to resuming low-dose acetylsalicylic acid (ASA) by evaluating our patients' resumption of low-dose ASA at various times after burr-hole drainage of the hematoma. In our retrospective study, 140 consecutive patients taking low-dose ASA undergoing surgical evacuation of cSDH were included. Data included baseline characteristics and rates of recurrence, morbidity, and mortality. A multivariate logistic regression model analyzed the association between ASA resumption time and recurrence rates. No statistically significant association was observed between early postoperative resumption of low-dose ASA and recurrence of cSDH (odds ratio, 1.01; 95% confidence interval, 1.001-1.022; P = .06). Corresponding odds ratios and risk differences for restarting ASA treatment on postoperative days 1, 7, 14, 21, 28, 35, or 42 were estimated at 1.53 and 5.9%, 1.42 and 5.1%, 1.33 and 4.1%, 1.23 and 3.2%, 1.15 and 2.2%, 1.07 and 1.1%, and 1.01 and 0.2%, respectively (P > .05). Cardiovascular event rates, surgical morbidity, and mortality did not significantly differ between patients with or without ASA therapy. Given the few published studies regarding ASA use in cranial neurosurgery, our findings elucidate one issue, showing comparable recurrence rates with early or late resumption of low-dose ASA after burr-hole evacuation of cSDH.

    Acute subdural hematoma (ASDH) is the most important cause of severe head injuries occurring during judo practice in Japan. Repeated head injuries have been reported as a cause of fatal ASDH, although the mechanism remains unknown. A 16-year-old boy visited an emergency department with vomiting 3 days after a strong blow to the occipital region during judo practice. Although computed tomography was performed at that time, a small interhemispheric ASDH was overlooked. The patient sustained another head injury 19 days after the first, which led to convulsions and disturbance of consciousness. The ASDH was increased in size on computed tomography. We performed a surgical evacuation, which revealed tearing of a bridging vein, after which the patient showed a good recovery. It is important to be aware of the possibility of a small ASDH in concussed judo players after an initial impact, which may lead to subsequent fatal ASDH after another impact incident.

    Passive drainage systems are commonly used after subdural hematoma evacuation but there is a dearth of published data regarding the suction forces created. We set out to quantify the suction forces generated by a passive drainage system. We created a model of passive drainage after subdural hematoma evacuation. We measured the maximum suction force generated with a bile bag drain for both empty drain tubing and fluid-filled drain tube causing a siphoning effect. We took measurements at varying heights of the bile bag to analyze if bile bag height changed suction forces generated. An empty bile bag with no fluid in the drainage tube connected to a rigid, fluid-filled model creates minimal suction force of 0.9 mmHg (95% CI 0.64-1.16 mmHg). When fluid fills the drain tubing, a siphoning effect is created and can generate suction forces ranging from 18.7 to 30.6 mmHg depending on the relative position of the bile bag and filled amount of the bile bag. The suction forces generated are statistically different if the bile bag is 50 cm below, level with or 50 cm above the experimental model. Passive bile bag drainage does not generate significant suction on a fluid-filled rigid model if the drain tubing is empty. If fluid fills the drain tubing then siphoning occurs and can increase the suction force of a passive bile bag drainage system to levels comparable to partially filled Jackson-Pratt bulb drainage.

    Background: Chronic subdural hematoma (CSDH) is one of the most common clinical entities in daily neurosurgical practice which carries a most favorable prognosis. However, because of the advanced age and medical problems of patients, surgical therapy is frequently associated with various complications. This study evaluated the clinical features, radiological findings, and neurological outcome in a large series of patients with CSDH. Methods: A classification and regression tree (CART) technique was employed in the analysis of data from 986 patients who were operated at Asclepeion General Hospital of Athens from January 1986 to December 2011. Burr holes evacuation with closed system drainage has been the operative technique of first choice at our institution for 29 consecutive years. A total of 27 prognostic factors were examined to predict the outcome at 3-month postoperatively. Results: Our results indicated that neurological status on admission was the best predictor of outcome. With regard to the other data, age, brain atrophy, thickness and density of hematoma, subdural accumulation of air, and antiplatelet and anticoagulant therapy were found to correlate significantly with prognosis. The overall cross-validated predictive accuracy of CART model was 85.34%, with a cross-validated relative error of 0.326. Conclusions: Methodologically, CART technique is quite different from the more commonly used methods, with the primary benefit of illustrating the important prognostic variables as related to outcome. Since, the ideal therapy for the treatment of CSDH is still under debate, this technique may prove useful in developing new therapeutic strategies and approaches for patients with CSDH.

    Small anterior communicating artery aneurysms with recurrent bleeding and adjacent hematoma may have a high risk of post-operative rebleeding. This clinical study summarizes our preliminary experience with this subset of aneurysms, which were treated with endovascular coiling and subsequent Onyx 34 embolization. We retrospectively reviewed the data of 9 patients suffering from small anterior communicating artery aneurysms treated with the combination of coils and Onyx. The clinical characteristics, angiographic outcomes, and follow-up results are reviewed. Endovascular coiling and Onyx embolization were successfully accomplished in all 9 cases. The Raymond scale ratings of the treatments are all class I with the parent arteries kept patent. One patient died of severe brain edema on the 5th post-operative day. The modified Rankin scale (mRS) score for the other 8 patients at follow-ups (6m to 26m, 15.8m on average) was 0 in 5 cases, 1 in 2 cases, and 3 in 1 case. Seven of 8 patients (87.5%) underwent angiographic follow-up that demonstrated persistent durable occlusion with no recanalization. Endovascular coiling and subsequent Onyx 34 embolization may be effective in treating anterior communicating artery aneurysms with adjacent hematoma. Further studies with larger sample size and adequate follow-up are required to verify its safety and efficacy as well as to evaluate the long-term outcome. Copyright © 2014 Elsevier B.V.

    Warfarin is the most common and cheap oral anticoagulant currently used in clinical practice. A high inter-individual variation is seen in the response to warfarin. Recently, pharmacogenetics has gained importance in managing patients on warfarin, both in predicting the optimum required dose as well as in decreasing the risk of bleeding. This case report is a description of a 49-year-old patient who had a lethal subdural hematoma with low-dose warfarin. He was subsequently found to have CYP2C9 gene polymorphism (*1/*3). This case report stresses the importance of pre-prescription assessment of genetic analysis for those initiated on warfarin. PMID:25298588

    Management of nonemergent, nonacute subdural hematomas (SDHs) ranges from observation to burr-hole evacuation or craniotomy, but recurrence rates are high. We evaluated the safety and efficacy of tranexamic acid (TXA) for the treatment of residual SDHs after bedside twist-drill evacuation. We performed a retrospective analysis of a prospectively maintained database from November 2013 to November 2014 for all patients who underwent placement of a bedside subdural evacuating port system (SEPS) followed by treatment with oral TXA (650 mg daily). All demographics, evidence of venous thromboembolism, and volumes of pertinent computed tomography were obtained. Twenty subdural hematomas in 14 patients met the inclusion criteria for this study. Most SDHs were mixed density. Mean SDH volume on presentation was 145.96 ± 40.22 cm(3) with a mean midline shift of 9.44 ± 4.84 mm. Mean volumes decreased to 80.00 ± 31.96 cm(3) and midline shift improved to 4.44 ± 3.29 mm after SEPS placement (P < 0.0001 and P = 0.0046). All patients were placed on TXA after their procedure. Mean follow-up with computed tomography was 92.1 ± 27.5 days, and mean SDH volume at last follow-up was 7.41 ± 15.54 cm(3) with a mean midline shift of 0.19 ± 0.69 mm (P < 0.0001 and P = 0.0002). Percent volume reduction was significantly higher after TXA than after SEPS (91.31% vs. 40.74%; P < 0.0001). No increase or delayed recurrence of the SDH was noted during TXA treatment. All but 1 clinical presenting symptom improved at follow-up. No venous thromboembolisms were noted among the patients. In our pilot study, chronic SDH volumes were reduced by 40.74% after SEPS drainage. The residual volume was reduced by an additional 91.31% during oral TXA treatment. No patients developed delayed recurrence or expansion of their SDHs. Further prospective studies are needed to evaluate the role of TXA for adjunctive treatment of chronic SDHs.

    Hematoma of the ligamentum flavum (LF) is a rare cause of neural compression and sciatica. Currently, the etiology and epidemiological characteristics of ligamentum flavum hematoma (LFH) are unknown and epidemiological investigations using rewieving of reported cases have not been performed. We report the case of a 63-year-old man with a LFH compressing the spinal canal at the left L2–L3 level, rewieved relevant literature. In Medline research, wefound a total of 50 reported cases with LFHs, and the interesting point of these cases were analyzed. Many of cases were old males. Interestingly, 39 of the 50 cases were reported from Asian countries. The ages of 42 patients could be verified. The youngest age was 45 years, oldest age was 81 years, and mean age was 66.07 years. Thirty-three out of these 42 patients (78.53%) were older than 60 years. An important aspect of the present review is to bring attention for occurrence in older Asian males. With an increasing number of elderly people in the general population, there is a need to investigate risk factors such as sexual gender, age, and geographic location for LFH. PMID:27041879

    Subacute subdural hematoma (SASDH) is an entity which is yet to capture the popular imagination among the neurosurgeons. Its management is often equated clinically to that of the chronic subdural hematoma (CSDH). However, their neurological deterioration is usually rapid, which seems to align them with acute subdural hematoma (ASDH). We proceed for their epidemiological evaluation. The advantages of a novel "double barrel technique (DbT)" over the conventional burrhole drainage are also presented. This retrospective study was conducted on all the patients having clinical and radiological evidence of SASDH, admitted to a tertiary care referral institute, during the period August 2013 to December 2015. Postoperatively, patients were followed-up for 3-24 months. 46.87% of the patients belonged to the 35-54 year age group with a male predominance (3.6:1); 68.7% had a history of alcohol abuse, whereas aspirin users were 25%. 87.5% cases were unilateral, 18.75% were hemispheric, and 46.87% were present on the left side. Altered consciousness (100%) followed by headache (37.5%) were the most common presenting clinical features. SASDH is an uncommon neurosurgical entity (0.89% of traumatic brain injury cases in our study) and mimics both CSDH as well as ASDH. The true incidence of SASDH may have been underestimated due to its clinical imitation with CSDH. This study in a South Asian nation also provides the epidemiological data of this rare neurosurgical entity. Outcome of surgery is good; our retrospective study confirms that "DbT" is an adequate and safe treatment. However, a better designed, randomized control trial will be needed to reinforce our findings.

    A 34-year-old man presented with a case of subdural empyema and cerebral abscess that developed 12 years after initial neurosurgical intervention for a traffic accident in 1998. Under a diagnosis of acute subdural hematoma and cerebral contusion, several neurosurgical procedures were performed at another hospital, including hematoma removal by craniotomy, external decompression, duraplasty, and cranioplasty. The patient experienced an epileptic seizure, and was referred to our hospital in March 2010. Magnetic resonance imaging revealed a cerebral abscess extending to the subdural space just under the previous surgical field. Surgical intervention was refused and antimicrobial treatment was initiated, but proved ineffective. Surgical removal of artificial dura and cranium with subdural empyema, and resection of a cerebral abscess were performed on May 12, 2010. No organism was recovered from the surgical samples. Meropenem and vancomycin were selected as perioperative antimicrobial agents. No recurrence of infection has been observed. Postneurosurgical subdural empyema and cerebral abscess are recently emerging problems. Infections of neurosurgical sites containing implanted materials occur in 6% of cases, usually within several months of the surgery. Subdural empyema and cerebral abscess developing 12 years after neurosurgical interventions are extremely rare. The long-term clinical course suggests less pathogenic organisms as a cause of infection, and further investigations to develop appropriate antimicrobial selection and adequate duration of antimicrobial administration for these cases are needed.

    Sub-acute/chronic epidural hematoma (EDH) may present with nagging symptoms of headache, nausea, vomiting, lethargy, etc. We attempted to offer a minimally invasive, single burr hole, endoscope-assisted evacuation of EDHs instead of a conventional craniotomy. Seven patients with sub-acute/chronic EDH (six supratentorial and one infratentorial) presented to us 3 to 7 days after low-velocity road traffic accidents with complaints of headache and lethargy. The EDH volumes measured between 20 to 50 ml, and the patients were operated on using a single burr hole made through a small incision. We used 0-, 30- and 70-degree, angulated, rigid, high-definition endoscopes to identify and evacuate the organized clots in the extradural space. Flexible catheters were used for suction and irrigation. After achieving hemostasis, the dura was hitched back to the burr hole site. The wound was closed over a negative suction drain. All patients had prompt recovery from symptoms. Postoperative CT scans showed complete or near complete evacuation of the hematomas. The hospital stay and analgesic requirements were minimal. There was no infective complication or conversion to conventional open surgery. The average time for surgery was 77.8 min, and average blood loss was 328.5 ml. Endoscope-assisted evacuation of sub-acute/chronic EDH is a novel concept, which offers quick relief from symptoms in a minimally invasive fashion and a cosmetically acceptable way. None of the standard principles of surgery are hampered. It avoids extensive dissection of the temporalis or sub-occipital muscles. However, achieving hemostasis can be difficult. Further study and better equipment will validate the procedure.

    A considerable body of evidence supporting the use of external drainage after evacuation of primary chronic subdural hematoma (CSDH) exists in the literature. However, no systematic study of the value of postoperative drainage in the treatment of recurrent CSDH has been published. The aim of the study was to investigate external drains and subdural-to-peritoneal conduit in the treatment of recurrent CSDH. A retrospective review of cases of CSDH treated in our institution between October 2002 and October 2006 was conducted. During the study period, 408 patients had burr hole evacuation. Sixty-four patients (15.9%) had treatment for recurrence. One patient had craniotomy, and the remaining 63 had another burr hole evacuation: 36 without placement of a drain (BHO), 14 with external drainage (SED), and 13 with placement of subdural-peritoneal catheter (SPC). Fifteen patients (24%) developed a secondary recurrence requiring a third drainage procedure. Postoperative drainage (SED or SPC) was associated with a significantly lower secondary recurrence rate when compared to BHO: 3/27 (11%) versus 12/36 (33%) (χ(2), P=.040). There was no significant difference in recurrence rates between SED and SPC. Postoperative complications included acute subdural hematoma (2), subdural empyema (2), brain edema (2), pneumonia (3), and in-hospital death (2). None of the complications was associated with the use of a specific technique. The results indicate that, as in the treatment of primary CSDHs, the use of drain (SED or SPC) with burr hole evacuation is safe and is associated with lower recurrence rate. Further investigation is needed to clarify the indications of currently available surgical techniques in the treatment of recurrent CSDH. Copyright © 2010 Elsevier Inc. All rights reserved.

    We report the clinical observation of a 58-year old patient who presented with upper abdominal pain and a small ecchymosis located in the umbilical area. Personal history of the patient revealed ischemic heart disease and chronic atrial fibrillation. He was under treatment with oral anticoagulants (coumarins). The clinical data and especially the imaging investigations led to a diagnosis of gastric wall hematoma, possibly occurring post-traumatically in a patient under anticoagulant treatment. A conservative therapeutic approach was adopted and ultrasound surveillance. After 6 months the gastric parietal collection manifested complete resorption, spontaneously. In relation to the case presentation, we also discuss some issues on the frequency, diagnosis and therapeutic attitude in this rare complication of anticoagulant therapy.

    Although chronic subdural hematoma (CSDH) is one of the most common entities encountered in neurosurgical practice, optimal surgical treatment for CSDH remains controversial. This study retrospectively compared results for CSDH between burr hole drainage alone and burr hole drainage with irrigation. Ninety-two patients with CSDH underwent surgery at our institution from January 1998 through December 2009. Fifty-eight patients received burr hole drainage alone (Group A), while 34 patients were treated using burr hole drainage with irrigation (Group B). Outcomes, recurrence rates, and death rates for the two groups were analyzed. Age, sex ratio, consciousness level on admission, radiodensity of hematoma on computed tomography before surgery, and duration of hospitalization were nearly the same in both groups. No significant differences were seen in good outcomes or death rates between groups, but poor outcomes were significantly more frequent in Group A (p=0.009). The recurrence rate was higher in Group A compared to Group B (10.3% vs. 2.9%). The authors used logistic regression analysis to identify factors associated with the outcome of CSDH, and found that duration of hospital stay, anti-coagulant therapy, presence of dementia and burr hole drainage alone were significantly associated with poor outcome of CSDH. These results indicate that burr hole drainage with irrigation has a significantly stronger association with good outcomes compared to drainage alone, and could be a reliable and effective operative method for the treatment of CSDH with a lower recurrence rate.

    Patients with traumatic subdural hygroma (SDG) are at an increased risk of developing chronic subdural hematoma (CSDH). However, the mechanism by which this occurs is still not fully understood. The purpose of this paper is to investigate the clinical characteristics and pathogenesis of CSDH, as well as the relationship between CSDH and SDG. We review the pertinent literature and retrospectively examine a series of cases in which CSDH had been preceded by SDG to understand the natural history and developmental mechanisms of these lesions. We discuss the cases of 24 patients in whom CSDH developed from traumatic SDG between 2001 and 2005. Headache was the most common symptom, and the mean Glasgow Coma Scale score was 14.1. Increases in SDG volume were observed in CT scans of 17 patients, and increased density and volume was observed in five patients. The mean interval between the two diseases was 57.6 days, and 13 patients developed new symptoms after the development of CSDH. The most common symptoms at that time were headache and hemiparesis. All patients underwent an operation, which resulted in good recovery in all but one case. The cycle of persistent SDG, rebleeding, coagulation and fibrinolysis contributes to the development of CSDH from SDG. It is important to understand the natural history of CSDH and carefully follow up patients with head injury, especially if it is associated with SDG, and the potential for the development of CSDH should be considered.

    Rectus sheath hematoma (RSH) is an uncommon but significant cause of acute abdominal pain in patients presenting to the Emergency Department. RSHs are often misdiagnosed as other more common causes of abdominal pain. This case describes a 23-year-old male presenting with acute abdominal pain, scrotal swelling, and associated scrotal pressure. The case highlights the uniqueness of this particular presentation and the clinical features, risk factors, diagnosis, and treatment of RSH. Published by Elsevier Inc.

    Recent studies have shown that blood glutamate grabbing is an effective strategy to reduce the excitotoxic effect of extracellular glutamate released during ischemic brain injury. The purpose of the study was to investigate the effect of two of the most efficient blood glutamate grabbers (oxaloacetate and recombinant glutamate oxaloacetate transaminase 1: rGOT1) in a rat model of intracerebral hemorrhage (ICH). Intracerebral hemorrhage was produced by injecting collagenase into the basal ganglia. Three treatment groups were developed: a control group treated with saline, a group treated with oxaloacetate, and a final group treated with human rGOT1. Treatments were given 1 hour after hemorrhage. Hematoma volume (analyzed by magnetic resonance imaging (MRI)), neurologic deficit, and blood glutamate and GOT levels were quantified over a period of 14 days after surgery. The results observed showed that the treatments used induced a significant reduction of blood glutamate levels; however, they did not reduce the hematoma, nor did they improve the neurologic deficit. In the present experimental study, we have shown that this novel therapeutic strategy is not effective in case of ICH pathology. More importantly, these findings suggest that blood glutamate grabbers are a safe treatment modality that can be given in cases of suspected ischemic stroke without previous neuroimaging.

    Objective Chronic subdural hematoma has an increasing incidence and results in high morbidity and mortality. We review here the ten-year experience of a single institution and the literature regarding the treatment and major associations of chronic subdural hematoma (cSDH). Methods We retrospectively reviewed all cSDHs surgically treated from 2000 to 2010 at our institution to evaluate duration from admission to treatment, type of treatment, length of stay in critical care, length of stay in the hospital and recurrence. The literature was reviewed with regards to incidence, associations and treatment of cSDH. Results From 2000–2008, 44 patients were treated with burr holes. From 2008 to 2010, 29 patients were treated with twist drill evacuation (SEPS). 4 patients from each group were readmitted for reoperation (9% vs. 14%; p=.53). The average time to intervention for SEPS (11.2±15.3 hrs) was faster than for burr holes (40.3±69.1 hrs) (p=.02). The total hospital LOS was shorter for SEPS (9.3±6.8 days) versus burr holes (13.4±10.2 days) (p=.04); both were significantly longer than for a brain tumor patient undergoing craniotomy (7.0±0.5 days, n=94, P<.01). Conclusion Despite decreasing lengths of stay over time as treatment for cSDH evolved from burr holes to SEPS, the length of stay for a cSDH is still greater than that of a patient undergoing craniotomy for brain tumor. We noted 11% recurrence in our series of patients, which included individuals who recurred as late as 3 years after initial diagnosis. PMID:23485050

    Vertex epidural hematomas (VEDHs) are an uncommon situation and difficulties may be encountered in their diagnosis and management. This is more complicated when the surgical management has to be performed by general surgeons, not specialized in neurosurgery, in a remote location. It was in this context that we were brought to care in charge a 2-year-old boy who required a neurosurgical emergency rescue for a severe VEDH in Djibouti. Through the description of this case, we want to emphasize the value of developing a network of teleconsultation for the benefit of remote and isolated locations and learning basic techniques of emergency neurosurgery.

    To investigate the effects of emergency burr hole drainage for acute subdural hematoma (ASDH) with bilateral non-reactive pupils. A retrospective study was conducted by reviewing medical records from 1998 to 2007. Patients meeting the following criteria were included: 1) head injury with unconsciousness (Glasgow Coma Scale score 8); 2) bilateral non-reactive pupils on arrival; 3) ASDH with disappearance of basal cistern on computed tomography (CT); and 4) performance of emergency single burr hole drainage. Subjects were divided into survival and non-survival groups. Pupil size on the small side was significantly smaller in the survival group than in the non-survival group. All pupils on the small side in the survival group were 4 mm. Emergency burr hole drainage should still be considered in patients with ASDH showing bilateral non-reactive pupils and one pupil 4 mm.

    Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolizationmore » angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.« less

    The purpose of this study was to investigate whether the intensity of trauma influences the pathogenesis of traumatic chronic subdural hematoma (CSDH). Thirty-one patients treated surgically for traumatic CSDH were divided into high-impact and lowimpact groups according to the intensity of trauma. They were respectively evaluated with respect to clinical and radiological findings at presentation, and the subdural concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8), vascular endothelial growth factor (VEGF), basic fibroblast growth factor, and beta-trace protein (ΒTP) [a highly specific protein in the cerebrospinal fluid (CSF)] related to the pathogenesis of CSDH. If ΒTP (subdural fluid/serum) was > 2, an admixture of CSF to the subdural fluid was indicated. The ΒTP (subdural fluid/serum) was > 2 in all patients with a traumatic CSDH. The mean concentration of subdural ΒTP in the high-impact group was higher than in the low-impact group (6.1 mg/L versus 3.9 mg/L), and the difference was statistically significant (p=0.02). In addition, mean concentrations of IL-6, IL-8 and VEGF were higher in the high-impact group, as compared to the low-impact group, though the differences did not reach statistical significance. Trauma may be related to CSF leakage into the subdural space in CSDH, and the intensity of trauma may influence the amount of CSF leakage. Although there is no direct correlation between the amount of CSF leakage and other subdural molecules, the intensity of trauma may be associated with larger concentrations of molecules in traumatic CSDH.

    Spinal cord injury (SCI) is one of the common complications of spinal surgery. There is no definite treatment and time of decompression for spinal cord induced by epidural hematoma during vertebroplasty. A total of 6 patients with SCI during vertebroplasty were included in our research. All of them occurred sensory disturbance and motor dysfunction due to a lower or same level operative vertebral body lesion in vertebroplasty. Neurological manifestations during vertebroplasty, postoperative magnetic resonance imaging and computed tomography. Once SCI occurred in vertebroplasty, four patients were underwent spinal cord decompression immediately, and two patients were done after 14 and 22 hours, respectively. Before decompression operation, one patient was Frankel A, three were Frankel B, and two were Frankel C. One day after evacuation of the SEH, three patients recovered to normal neurological function (Frankel E), one to Frankel C, and one to Frankel D, but the other one did not recover. At the last follow-up, five patients had recovered to Frankel E and one patient to Frankel D. According to our experience, when SCI occurs during vertebroplasty, neurological deficits are always secondary to acute SEH. Timely decompression, particularly transfer surgery, can shorten recovery time.

    Abstract Intramural duodenal hematoma (IDH) is a rare complication in endoscopic management of ulcer hemorrhage. Usually noted in cases of blunt abdominal trauma, non-traumatic IDHs have been reported in individuals on anticoagulation, with blood disorders, pancreatic diseases and in endoscopic procedures such as biopsy, sclerotherapy and argon plasma coagulation. Patients may be asymptomatic or present with acute blood loss anemia, abdominal pain or vomiting. We report a case of an 83-year-old man with melena and syncope who underwent endoscopy for bleeding ulcer control and subsequently developed acute pancreatitis due to an acute IDH. Computed tomography (CT) scan confirms the diagnosis. Most cases are conservatively managed however when unsuccessful, laparoscopic surgical drainage or ultrasound or CT guided drainage can be performed. PMID:29383264

    A 40-year-old man presented with a severe headache, lower back pain, and lower abdominal pain 1 month after a head injury caused by falling. Computed tomography (CT) of the head demonstrated bilateral chronic subdural hematoma (CSDH) with a significant amount in the left frontoparietal region. At the same time, magnetic resonance imaging (MRI) of the lumbar spine also revealed CSDH from L2 to S1 level. A simple drainage for the intracranial CSDH on the left side was performed. Postoperatively, the headache was improved; however, the lower back and abdominal pain persisted. Aspiration of the liquefied spinal subdural hematoma was performed by a lumbar puncture under fluoroscopic guidance. The clinical symptoms were dramatically improved postoperatively. Concomitant intracranial and spinal CSDH is considerably rare so only 23 cases including the present case have been reported in the literature so far. The etiology and therapeutic strategy were discussed with a review of the literature. Therapeutic strategy is not established for these two concomitant lesions. Conservative follow-up was chosen for 14 cases, resulting in a favorable clinical outcome. Although surgical evacuation of lumbosacral CSDH was performed in seven cases, an alteration of cerebrospinal fluid (CSF) pressure following spinal surgery should be reminded because of the intracranial lesion. Since CSDH is well liquefied in both intracranial and spinal lesion, a less invasive approach is recommended not only for an intracranial lesion but also for spinal lesion. Fluoroscopic-guided lumbar puncture for lumbosacral CSDH following burr hole surgery for intracranial CSDH could be a recommended strategy. PMID:29479039

    Introduction To address the mechanisms by which apoE polymorphism affects functional outcome after intracerebral hemorrhage in humans, we tested the hypothesis that the presence of the APOE4 allele results in amplified inflammatory responses and increased cerebral edema. Methods We prospectively enrolled and collected data on 21 adult patients consecutively admitted to Duke University Hospital with supratentorial intracerebral hematoma including hemorrhage volume, midline shift, modified Rankin Score, Glasgow Outcome Score, and APOE genotype. Hemorrhage size (cm3) and midline shift (mm), at the level of the thalamus, were measured by computed tomography within 36 hours of admission. Rankin and Glasgow Scores were determined at discharge. Student’s t-test was used to analyze hemorrhage size, midline shift, and Glasgow Outcome Score and logistical regression was used to measure allele affect on modified Rankin Score. When analyzing modified Rankin Score, patients were grouped by favorable outcome (0–2) or unfavorable (3–6). Results Out of 21 patients, 11 possessed at least one APOE4 allele (APOE4+). There was no difference in hemorrhage volume (25.8 v. 38.3 mm for APOE4− v. APOE4+, respectively) between the groups, but there was a significant difference in midline shift (p=0.04, 0.7 v. 4mm). Functional outcomes were worse for the patients possessing at least one APOE4 allele (p=0.04) Conclusion The presence of APOE4 is associated with poor functional outcomes in humans after intracerebral hemorrhage. Our data suggest that the mechanism for this may be increased cerebral edema and not larger hematoma volume. PMID:19251191

    The pathophysiology of acute-on-chronic subdural hematoma (ACSDH) is complex and incompletely understood. Evidence to date indicates that the overall process is initiated by rotational force with movement of the brain inside the skull, which exerts tensile strain and rupture of bridging veins, leading in turn to acute hemorrhage in the subdural potential space. This is followed by the proliferation of mesenchymal elements with angiogenesis and inflammation, which in turn becomes a substrate for repeated hemorrhage and expansion of the lesion. Given the prevalence of traumatic subdural processes in the forensic setting and the importance of proper assessment of timing, etiology, risk factors, and clinicopathological correlation, we studied 47 patients presenting to the University of Maryland Shock Trauma Center, all of whom underwent craniotomy with resection of the outer membrane due to symptomatic ACSDH. The surgically resected tissue was examined for histopathologic features in all cases. Our findings highlight that ACSDH is a condition precipitated by trauma that affects middle-aged and older adults, is relatively indolent, is unilateral or asymmetric, and has a low in-hospital mortality rate. Pathological analysis demonstrates a substantial outer membrane in all cases with varying degrees of inflammation and organization that cannot be precisely dated as a function of clinical presentation. The extrapolation of adult ACSDH to mixed acute and chronic subdural hemorrhage in the pediatric setting is problematic due to substantial differences in clinical presentation, severity of underlying brain injury, gross and microscopic findings, and outcome.

    The use of temporary epicardial pacing wires during cardiac surgery is a routine procedure and has been associated with low morbidity. We describe a rare case of right paracardiac mass due to organized pericardial hematoma with right atrial compression around the epicardial pacing wires left in-situ, presenting three months following aortic valve replacement surgery. The case highlights the fact that such delayed complications can rarely occur around retained epicardial pacing wires following open heart surgery especially in patients on oral anticoagulants. The clinician should be alert to such an occurrence and during follow-up echocardiography always pay attention not only to the valve and ventricular function, but also to the pericardial and extra-pericardial space.

    OBJECTIVE The goal of this study was to identify factors that contribute to the formation of acute spinal epidural hematoma (SEH) by correlating etiology, age, site, clinical status, and treatment with immediate results and long-term outcomes. METHODS The authors reviewed their series of 15 patients who had been treated for SEH between 1996 and 2012. In addition, the authors reviewed the relevant international literature from 1869 (when SEH was first described) to 2012, collecting a total of 1010 cases. Statistical analysis was performed in 959 (95%) cases that were considered valid for assessing the incidence of age, sex, site, and clinical status at admission, correlating each of these parameters with the treatment results. Statistical analysis was also performed in 720 (71.3%) cases to study the incidence of etiological factors that favor SEH formation: coagulopathy, trauma, spinal puncture, pregnancy, and multifactorial disorders. The clinical status at admission and long-term outcome were studied for each group. Clinical status was assessed using the Neuro-Grade (NG) scale. RESULTS The mean patient age was 47.97 years (range 0-91 years), and a significant proportion of patients were male (60%, p < 0.001). A bimodal distribution has been reported for age at onset with peaks in the 2nd and 6th decades of life. The cause of the SEH was not reported in 42% of cases. The etiology concerned mainly iatrogenic factors (18%), such as coagulopathy or spinal puncture, rather than noniatrogenic factors (29%), such as genetic or metabolic coagulopathy, trauma, and pregnancy. The etiology was multifactorial in 11.1% of cases. The most common sites for SEH were C-6 (n = 293, 31%) and T-12 (n = 208, 22%), with maximum extension of 6 vertebral bodies in 720 cases (75%). At admission, 806 (84%) cases had moderate neurological impairment (NG 2 or 3), and only lumbar hematoma was associated with a good initial clinical neurological status (NG 0 or 1). Surgery was performed in 767

    A 42-year-old female Indian elephant (Elephas maximus indicus) developed a sudden onset of excessive salivation and dysphagia. Esophageal obstruction was suspected; possibly related to palm frond ingestion. Esophageal endoscopy revealed a mat of plant material in the distal esophagus. An initial attempt at relieving the obstruction was unsuccessful, but subsequent use of custom-made instruments along with insufflation and hydropulsion enabled partial removal of the material. Postimmobilization care included aggressive intravenous and rectal fluids, anti-inflammatory and antibiotic administration, and fasting. Despite treatment, the dysphagia persisted and the elephant was euthanized due to lack of improvement and grave prognosis. Postmortem examination revealed remaining plant material in the esophagus, complicated by an esophageal dissection, mural hematoma, and secondary bacterial infection. Iatrogenic trauma may have contributed to the extent of esophageal injury. Although treatment was ultimately unsuccessful, the supportive care employed could potentially aid recovery in cases of less severe esophageal trauma.

    The patient is a 79-year-old male, suffering from advanced metastatic prostate cancer, who developed a progressively worsening ideomotor slowing and was therefore referred to the emergency department of our institution. A plain axial computed tomography (CT) scan revealed a vast hemispheric subdural fluid collection, apparently a subdural hematoma. On closer inspection, and most of all, in hindsight, a tenuously isohyperdense signal irregularity at the frontal aspect of the fluid collection appears. Because of the declined general medical conditions and the paucity of the neurologic impairment, a high-dose, corticosteroid-based conservative strategy was performed. The total body CT scan for the routine oncologic follow-up of the prostate cancer scan fell at 20 days from the first CT of the emergency department. A second contrast-enhanced axial CT scan demonstrated the presence of 2 subdural metastases, presumably the initial pathogenesis of the subdural fluid collection. Copyright © 2017 Elsevier Inc.

    The incidence of chronic Subdural hematoma (cSDH) is increasing and its rate of recurrence varies from 5 to 33%. A postoperative brain midline-shift (MLS) on computed tomography (CT) equal or larger than 5mm is a risk factor for recurrence. Transcranial color-coded duplex sonography (TCCDS) is a noninvasive bedside reproducible technique useful to detect MLS. The aim of our study was to compare in patients affected by cSDH, the values of MLS obtained pre- and post-operatively by TCCDS and brain CT. 32 patients affected by cSDH entered the study between July 2016 and January 2017. MLS values obtained by TCCDS and brain CT were compared using Bland-Altman plot and linear regression analysis. Using the same techniques we also explored if the agreement between the two imaging modes was comparable in pre- and post-operative data pairs. 64 data pairs of MLS values obtained by TCCDS and CT were analysed. Bland-Altman diagrams did not show any systematic bias of the data and linear regression indicated a significant correlation between the two measures both before and after hematoma evacuation. In patients affected by cSDH, MLS values obtained before and after surgery by TCCDS are comparable to those obtained by CT; TCCDS might be considered an alternative to CT scan in the management of patients after cSDH evacuation. We suggest that close clinical bedside examination and TCCDS might be appropriate for the post-operative management of cSDH, reserving CT scan only to patients with overt clinical deterioration and/or increasing MLS.

    Spinal epidural hematomas are uncommon in children. The diagnosis can be elusive as most cases present without a history of trauma, while symptoms can be atypical. We encountered a 35-month-old male presenting with nonspecific symptoms and no history of trauma. He later developed unilateral miosis and ptosis; MRI discovered a subacute cervicothoracic epidural which was promptly evacuated. The patient made an excellent recovery. We emphasize the frequent absence of identifiable trauma and the importance of thorough imaging when this entity is suspected. Miosis and ptosis, likely representing a partial Horner syndrome, is an extremely rare presentation, this being one of the only reported cases.

    Twist-drill craniostomy (TDC) with closed-system drainage is a less invasive surgical technique for the treatment of chronic subdural hematoma (CSDH), but results in a higher disease recurrence rate. Therefore, we aimed to modify the TDC procedure in order to reduce the recurrence rate and further decrease complications. We retrospectively reviewed 230 cases of standard CSDH in 202 patients treated in our hospital between January 2006 and December 2013. We employed a new TDC device called micro-steel-needle-tube-bit for puncture and drainage. We chose an entry point 0.5cm anterior to the coronal suture at the superior temporal line and maintained post-operative drainage with urokinase instillation into the hematoma cavity. Clinical performance was assessed and compared by the Markwalder Grading Scale (MGS) score during the pre-operative period and at discharge. Recurrence of CSDH and complications were also recorded. Mean operation time was only 8.9 (6-13) min. Mean catheter indwelling duration and hospital stay were 1.18 (271/230, 1-3) and 2.27 (458/202, 2-9) days, respectively. The average frequency of urokinase instillation was 1.14 (262/230, 1-3) times. Intracerebral and sub-arachnoid hemorrhages were found in one patient, but were not in the puncture pathway. No perioperative deaths occurred. Recurrence was observed in only one patient at 28 days post-operation. Among 202 patients, 193 (95.54%) showed improved clinical symptoms and neurological function, and significantly lower MGS scores at discharge than pre-operation (0.13±0.45 vs. 1.37±0.55, P<0.01). In conclusion, electric TDC with micro-steel-needle-tube-bit at the pre-coronal suture entry point might be a safer, simpler, and faster mini-invasive surgical procedure for CSDH treatment. Post-operative drainage with instillation of urokinase could dramatically shorten drainage time and decrease recurrence rate. Copyright © 2015 Elsevier B.V. All rights reserved.

    Spinal subdural hematomas (SDHs) are rare and some are concomitant with intracranial SDH. Their pathogenesis and etiology remain to be elucidated although their migration from the intracranial space has been suggested. The authors postulated that if migration plays a major role, patients with intracranial SDH may harbor asymptomatic lumbar SDH. The authors performed a prospective study on the incidence of spinal SDH in patients with intracranial SDH to determine whether migration is a key factor in their concomitance. The authors evaluated lumbar MR images obtained in 168 patients (125 males, 43 females, mean age 75.6 years) with intracranial chronic SDH to identify cases of concomitant lumbar SDH. In all cases, the lumbar MRI studies were performed within the 1st week after surgical irrigation of the intracranial SDH. Of the 168 patients, 2 (1.2%) harbored a concomitant lumbar SDH; both had a history of trauma to both the head and the hip and/or lumbar area. One was an 83-year-old man with prostate cancer and myelodysplastic syndrome who suffered trauma to his head and lumbar area in a fall from his bed. The other was a 70-year-old man who had hit his head and lumbar area in a fall. Neither patient manifested neurological deficits and their hematomas disappeared under observation. None of the patients with concomitant lumbar SDH had sustained head trauma only, indicating that trauma to the hip or lumbar region is significantly related to the concomitance of SDH (p < 0.05). As the incidence of concomitant lumbar and intracranial chronic SDH is rare and both patients in this study had sustained a direct impact to the head and hips, the authors suggest that the major mechanism underlying their concomitant SDH was double trauma. Another possible explanation is hemorrhagic diathesis and low CSF syndrome.

    A 53-year-old-man underwent US-guided percutaneous thermal ablation with a cooled-tip needle of three liver metastases from gastric cancer. Six days later, the patient was re-admitted for melena, scleral jaundice, and anemia. Abdominal US disclosed echogenic material in the gallbladder lumen (hemobilia) and a focal lesion with mixed echotexture in segment III (hepatic hematoma). On day 5 portal cavernomatosis was diagnosed at US and confirmed by color Doppler and a helical CT exam. The case described emphasizes that radio-frequency interstitial hyperthermia may cause not only traumatic injury of the liver parenchyma but also thermally mediated damage of vascular structures.

    Preeclampsia, HELLP syndrome (hemolysis, elevated liver enzymes, and low-platelet count), and acute fatty liver of pregnancy are the main causes of thrombotic microangiopathy and evere liver dysfunction during pregnancy and represent different manifestations of the same pathological continuum. The case of a 35-week pregnant woman who was admitted to an intensive care unit immediately after a Cesarean section due to fetal death and the presence of nausea, vomiting, and jaundice is reported. Postpartum preeclampsia and acute fatty liver of pregnancy were diagnosed. The patient developed an acute subdural hematoma and an intracerebral hemorrhage, which were subjected to neurosurgical treatment. The patient died from refractory hemolytic anemia and spontaneous bleeding of multiple organs. Preeclampsia HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure management and treatment success.

    Benign external hydrocephalus (BEH) is considered a self-limiting condition in infants. Subdural hematoma (SDH) in infants without a history of trauma indicates nonaccidental injury (NAI). The authors studied whether SDH can complicate BEH without apparent trauma. Out of 45 children younger than 3 years with nontraumatic SDH, 9 (7 boys) with mean age 6 months had BEH as risk factor. Symptoms included increasing head size (8), fussiness, and irritability (3). Three had up-gaze restriction, 1 axial hypotonia, and 6 normal examination. Neuroimaging showed prominent extra-axial spaces; SDH was bilateral (6), subacute (5). Other etiological workup for SDH was negative except NAI in 1. Two required evacuation of SDH and subdural-peritoneal shunt; others managed conservatively. Development was normal in 8 on follow-up. On follow-up imaging of 8, SDH completely resolved in 3, markedly reduced in 3, and remained stable in 2. BEH is a risk factor for SDH in infants, thus not always benign.

    A 57-year-old man complained of severe lower back pain and radicular pain in both legs for 1 week after falling from a ladder. Magnetic resonance imaging (MRI) of the spine showed a subdural hematoma (SDH), which was surgically removed. The patient had no back pain or the radicular leg pain at 2 weeks post-surgery. However, he complained of diffuse headaches upon follow-up. Brain computed tomography (CT) and MRI revealed an intracranial SDH, which was immediately removed by surgery. During his 1-year follow-up, he reported that the pain had resolved without recurrence. Simultaneous spinal and intracranial SDH are rare and no standard treatment exists for this condition. This case suggests that it is possible that an intracranial SDH can migrate into the cerebrospinal fluid (CSF) space through an arachnoid tear. CSF circulation allows the intracranial SDH to enter subarachnoid spaces encasing the spinal cord. In order to prevent irreversible damage, surgical intervention should be considered for case of spinal SDH with progressive neurological deficits.

    Spontaneous retroperitoneal hematoma after warfarin therapy is an extremely rare event. Here, we report a 25-year-old man who was brought in to the emergency service with confusion. On arrival, the patient had hypotension, tachycardia, tachypnea, low-grade fever, and Glasgow Coma Scale score of 12. Abdominal examination revealed distention and mild tenderness in the right upper quadrant of the abdomen. The patient had a history of aortic valve replacement surgery and was on warfarin treatment at an international normalized ratio of 2.4. Our patient progressed to cardiorespiratory arrest. The resuscitation was initiated promptly. Despite all resuscitation measures, including transfusion and administration of high doses of catecholamine, the patient died of hypovolemic shock 3 hours after admission. At autopsy, the external surface of the abdominal great vessels (descending aorta and mesenteric vessels) showed scattered petechial hemorrhages without any visible site of perforation. After comprehensive exploration of the abdomen, no evidence of traumatic event was identified and the cause of internal blood loss was noted as warfarin adverse effect.

    We report the first case report of symptomatic bilateral subdural hematomas (SDH) associated with riding a centrifugal motion simulator ride. A previously healthy 55-year-old male developed new onset daily headaches 1 week after going on the ride that were due to symptomatic bilateral SDH requiring operative intervention with a full recovery. There was no history of other trauma or other systemic or intracranial abnormality to account for the development of the SDH. We review the headaches and other clinical features associated with chronic SDH. Twelve cases of roller coaster headaches due to SDH associated with riding roller coasters have been reported. The pathophysiology is reviewed, which we believe is the same mechanism that may be responsible in this case. Although it is possible that this neurovascular injury is truly rare, it is also possible that this injury is underreported as patients and physicians may not make the association or physicians have not reported additional cases. The risk of this injury likely increases with age, as the size of the subdural space increases, and may support the maxim that "roller coasters and simulators are for kids." © 2015 American Headache Society.

    To observe the expressions of neurotrophin receptor homolog 2 (NRH2), nerve growth factor precursor (proNGF), sortilin and neurotrophin receptor p75 (p75NTR) in cerebral tissues around hematomas in the different periods after intracerebral hemorrhage, and explore their relationships to cell apoptosis. The specimens of cerebral tissues around hematomas were collected from the patients undergoing hematoma removal operation after intracerebral hemorrhage. These specimens were divided into four groups, namely ≤ 6 hours, 6-24 hours(including 24 hours), 24-72 hours (including 72 hours) and over 72 hours according to the time from intracerebral hemorrhage to specimen collection. At the same time, 10 brain tissues distant to hemorrhage that dropped in the operative process were collected as a control group. Apoptosis index (AI) was examined in brain cells by terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling (TUNEL). The expressions of NRH2, proNGF, sortilin and p75NTR mRNAs and proteins in brain tissues were detected through real-time quantitative PCR and Western blotting, respectively. Also, the expressions of Bcl-2 and Bax in brain tissues were analyzed using Western blotting. In vitro cultured astrocytes of rat cortex were transfected by NRH2 siRNA or scramble siRNA. The expressions of proNGF, sortilin and p75NTR proteins were detected using Western blotting. AI was higher in all groups of hemorrhage for 6 hours or longer than that in control and ≤ 6 hours groups, and AI in the group of 24-72 hours after intracerebral hemorrhage was the highest. However, there was no significant difference in AI between ≤ 6 hours group and control group. With the extension of intracerebral hemorrhage time, the expression levels of proNGF and p75NTR mRNAs and proteins were gradually elevated, reached the peak in 24-72 hours, and maintained a higher level after 72 hours, whereas there were no significant differences in the above indicators

    DEL red blood cells (RBCs) type as D- by routine serologic methods and are transfused routinely, without being identified as expressing a very weak D antigen, to D- recipients. DEL RBCs are detected only by adsorption and elution of anti-D or by molecular methods. Most DEL phenotypes have been reported in population studies conducted in East Asia, although DEL phenotypes have been detected also among Caucasian individuals. Approximately 98 percent of DEL phenotypes in East Asians are associated with the RHD*DEL1 or RHD*01EL.01 allele. The prevalence of DEL phenotypes has been reported among D- Han Chinese (30%), Japanese (28%), and Korean (17%) populations. The prevalence of DEL phenotypes is significantly lower among D- Caucasian populations (0.1%). Among the 3-5 percent of African individuals who are D-, there are no reports of the DEL phenotype. Case reports from East Asia indicate that transfusion of DEL RBCs to D- recipients has been associated with D alloimmunization. East Asian immigrants constitute 2.1 percent of the 318.9 million persons residing in the United States, and an estimated 2.8 percent are blood donors. Using these statistics, we estimate that 68-683 units of DEL RBCs from donors of East Asian ancestry are transfused as D- annually in the United States. Given the reports from East Asia of D alloimmunization attributed to transfusion of DEL RBCs, one would expect an occasional report of D alloimmunization in the United States following transfusion of DEL RBCs to a D- recipient. If such cases do occur, the most likely reason that they are not detected is the absence of active post-transfusion monitoring for formation of anti-D.

    The Brain Trauma Foundation has published guidelines on the surgical management of traumatic subdural hematoma (SDH). However, no data exist on the proportion of patients with SDH that can be selected for conservative management and what is the outcome of these patients. The goals of this study were as follows: 1) to establish what proportion of patients are initially treated conservatively; 2) to determine what proportion of patients will deteriorate and require surgical evacuation; and 3) to identify risk factors associated with deterioration and delayed surgery. All cases of acute traumatic SDH (869 when inclusion criteria were met) presenting over a 4-year period were reviewed. For all conservatively treated SDH, the proportion of delayed surgical intervention and the Glasgow Outcome Scale score were taken as outcome measures. Multiple factors were compared between patients who required delayed surgery and patients without surgery. Of the 869 patients with acute traumatic SDH, 646 (74.3%) were initially treated conservatively. A good outcome was achieved in 76.7% of the patients. Only 6.5% eventually required delayed surgery, and the median delay for surgery was 9.5 days. Factors associated with deterioration were as follows: 1) thicker SDH (p<0.001); 2) greater midline shift (p<0.001); 3) location at the convexity (p=0.001); 4) alcohol abuse (p=0.0260); and 5) history of falls (p=0.018). There was no significant difference in regard to age, sex, Glasgow Coma Scale score, Injury Severity Score, abnormal coagulation, use of blood thinners, and presence of cerebral atrophy or white matter disease. The majority of patients with SDH are treated conservatively. Of those, only 6.5% later required surgery, for raised intracranial pressure or SDH progression. Patients at risk can be identified and followed more carefully.

    To compare the efficacy and safety of multiple treatment modalities for the management of chronic subdural hematoma (CSDH) patients. Current management strategies of CSDHs remain widely controversial. Treatment options vary from medical therapy and bedside procedures to major operative techniques. We searched MEDLINE (PubMed and Ovid), EMBASE, CINAHL, Google scholar, and the Cochrane library from January 1970 through February 2013 for randomized and observational studies reporting one or more outcome following the management of symptomatic patients with CSDH. Independent reviewers evaluated the quality of studies and abstracted the data on the safety and efficacy of percutaneous bedside twist-drill drainage, single or multiple operating room burr holes, craniotomy, corticosteroids as a main or adjuvant therapy, use of drains, irrigation of the hematoma cavity, bed rest, and treatment of recurrences following CSDH management. Mortality, morbidity, cure, and recurrence rates were examined for each management option. Randomized, prospective, retrospective, and overall observational studies were analyzed separately. Pooled estimates, confidence intervals (CIs), and relative risks (RRs) were calculated for all outcomes using a random-effects model. A total of 34,829 patients from 250 studies met our eligibility criteria. Sixteen trials were randomized, and the remaining 234 were observational. We included our unpublished single center series of 834 patients. When comparing percutaneous bedside drainage to operating room burr hole evacuation, there was no significant difference in mortality (RR, 0.69; 95% CI, 0.46-1.05; P = 0.09), morbidity (RR, 0.45; 95% CI, 0.2-1.01; P = 0.05), cure (RR, 1.05; 95% CI, 0.98-1.11; P = 0.15), and recurrence rates (RR, 1; 95% CI, 0.66-1.52; P = 0.99). Higher morbidity was associated with the adjuvant use of corticosteroids (RR, 1.97; 95% CI, 1.54-2.45; P = 0.005), with no significant improvement in recurrence and cure rates. The use of

    Ventriculo-peritoneal shunt (VPS) continues to remain the main diverted method to drain the cerebrospinal fluid (CSF) from the ventricles to the peritoneal cavity. It has some complications that must be managed promptly to avoid any eventual fatal evolution. The association of delayed intracerebral and subdural hematomas after VPS insertion is a very rare complication and has, to our knowledge, never previously been reported in the literature. We report a very uncommon association of this entity occurring 11months after a shunt placement in a 13-year-old boy and discuss the likely pathogenesis, as well as the clinical and the radiological data.

    Real time noninvasive head injury detection is needed in critical care facilities and triage site with limited resources. One tool missing right now is a small and fast noninvasive sensor which can help urgent care workers to (1) diagnose the location and severity of the injury, (2) to perform on site pre-hospital treatment if necessary, and (3) to make a decision on what kind of further medical action is needed. On the other hand, continuous monitoring of cerebral blood oxygenation is also needed in intensive care unit and in operation rooms. Pseudo-random modulation/near infrared sensor (PRM/NIR sensor) is developed to address these issues. It relies on advanced techniques in diode laser cw modulation and time resolved spectroscopy to perform fast and noninvasive brain tissue diagnostics. Phantom experiments have been conducted to study the feasibility of the sensor. Brain's optical properties are simulated with solutions of intralipid and ink. Hematomas are simulated with bags of paint and hemoglobin immersed in the solution of varies sizes, depths, and orientations. Effects of human skull and hair are studied experimentally. In animal experiment, the sensor was used to monitor the cerebral oxygenation change due to hypercapnia, hypoxia, and hyperventilation. Good correlations were found between NIR measurement parameters and physiological changes induced to the animals.

    Chronic subdural hematomas are encapsulated blood collections within the dural border cells with characteristic outer "neomembranes". Affected patients are more often male and typically above the age of 70. Imaging shows crescentic layering of fluid in the subdural space on a non-contrast computed tomography (CT) scan, best appreciated on sagittal or coronal reformats. Initial medical management involves reversing anticoagulant/antiplatelet therapies, and often initiation of anti-epileptic drugs (AEDs). Operative interventions, such as twist-drill craniostomy (TDC), burr-hole craniostomy (BHC), and craniotomy are indicated if imaging implies compression (maximum fluid collection thickness >1 cm) or the patient is symptomatic. The effectiveness of various surgical techniques remains poorly characterized, with sparse level 1 evidence, variable outcome measures, and various surgical techniques. Postoperatively, subdural drains can decrease recurrence and sequential compression devices can decrease embolic complications, while measures such as early mobilization and re-initiation of anticoagulation need further study. Non-operative management, including steroid therapy, etizolam, tranexamic acid, and angiotensin converting enzyme inhibitors (ACEI) also remain poorly studied. Recurrent hemorrhages are a major complication affecting around 10-20% of patients, and therefore close follow-up is essential. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Subdural hematoma (SDH) is the most common finding on cranial CT in pediatric victims of abusive head trauma (AHT). The hematomas are commonly bilateral and sometimes associated with interhemispheric hyperdensity and/or convexity hemorrhages. There is no consensus regarding the best surgical treatment in such cases nor are there standardized surgical protocols. The authors report their experience and discuss the routine surgical options in the management of traumatic SDH at a Level 1 Pediatric Trauma Center. In this paper, the authors describe a cross-sectional study with consecutive revision of data described in the medical records of Hôpital Universitaire Necker-Enfants Malades between January 2008 and January 2013. During this period, all children younger than 2 years of age who were admitted with a traumatic SDH identified on CT scans were included in this study. One hundred eighty-four children who had SDH and were younger than 2 years of age were included. Their median age was 5.8 months (range 5 days-23 months), and 70% of the children were male. On admission CT scans, the SDH was bilateral in 52% of cases and homogeneously hypodense in 77%. Neurosurgical treatment was undertaken in 111 children (60%) with an admission Glasgow Coma Scale score of 12 or less, bulging fontanels, or other signs suggestive of intracranial hypertension. The first surgical option was craniotomy in 1.8% (2) of these 111 cases, decompressive craniectomy in 1.8% (2), transcutaneous subdural puncture in 15% (17), external subdural drainage in 16% (18), subdural-subgaleal shunt placement in 17% (19), and subdural-peritoneal shunt placement in 48% (53). In 82% of the children initially treated with transcutaneous subdural puncture and in 50% of those treated with external subdural drainage, increase or persistence of the SDH, CSF or skin infection, or shunt system malfunction was observed and further surgical intervention was required. There was a 26% rate of complications in patients

    An extrapleural hematoma (EH) is an uncommon and potentially life-threatening condition defined as the accumulation of blood in the extrapleural space between the parietal pleura and the endothoracic fascia. EH usually occurs after blunt thoracic trauma causing fractures of the sternum and ribs, which can tear the intercostal or internal mammary vessels. Typical radiological findings of EH are a biconvex opacity on the involved hemithorax and the so-called displaced "extrapleural fat sign." We present a case of a 36-year-old man with an isolated scapular fracture after a high-energy blunt chest trauma complicated with a large contralateral EH that was successfully managed nonoperatively with transcatheter arterial embolization (TAE) and image-guided drainage with a pig-tail catheter. To the best of our knowledge there is only one previous report describing a large EH after blunt thoracic trauma without rib fractures. Only two previous cases of large EHs have been treated initially with TAE, but both patients ultimately required open surgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients with EH can present with respiratory distress and hypotension, so early identification is important to facilitate proper treatment. EH has characteristic radiological findings, and contrast-enhanced computed tomography is not only the best imaging tool for confirming an EH, but also the best technique for detecting the source of the bleeding and other serious thoracic complications that may not be evident on chest x-ray studies.

    A 64-yr-old male was admitted to the hospital with severe abdominal pain associated with vomiting. Upon examination, the patients Hgb was 7.8 with a WBC count of 13.3 band cells of 7 and a recticulocyte count of 3.4, no evidence of gastrointestinal bleeding. The patient's prior history revealed involvement in an automobile accident approx. 10 days prior to this admission. At that time, he suffered multiple contusions and abrasions with a fracture to his left clavicle. Apparently there were no episodes of abdominal pain or vomiting prior to the onset of illness perceived on the day of admission. A liver/spleenmore » scan was done. Four millicuries of /sup 99m/Tc-sulfur colloid were intravenously injected using a bolus injection technique while obtaining multiple dynamic images. The flow study was unremarkable, demonstrating no abnormalities to the great vessels and good perfusion to both organs. Static images of the liver and spleen revealed a straightening or flatness to the lateral border of the spleen with a small diminished area of tracer sulfur colloid localization at the posterolateral aspect of that organ. This finding raised the suspicion that a small subcapsular hematoma had developed at the mid-posterolateral aspect of the spleen. Twenty-four hours after hospital admission, 4 units of packed RBCs were transfused into the patient. Although there was at this time still no evidence of abnormal bleeding, it was felt that because of the strong symptomatic correlation for internal bleeding, a radionuclide bleeding site study should be ordered and immediately performed.« less
