    Blunt traumatic thoracic aortic injury (BTTAI) is a lethal injury associated with a prehospital mortality of 80% to 90%. Patients arriving in the emergency room and considered appropriate to undergo emergency open surgical repair still have a mortality rate of 15% to 30% because of severe associated injuries. Conventional open surgical repair requires a left thoracotomy, single lung ventilation, aortic-cross clamping and unclamping, with or without the adjunct use of partial or full cardiopulmonary bypass and systemic heparinization. All this leads to significant physiological stress and surgical trauma resulting in perioperative complications such as major blood loss, coagulopathy, myocardial infarction, stroke, respiratory failure, renal failure, bowel infarction, and paraplegia. Despite advances in anesthesia, critical care medicine, and surgical techniques, a recent meta-analysis showed no definite improvement in operative mortality over the past decade, following open surgical repair in patients with BTTAI. Endovascular repair of BTTAI does not require a thoracotomy, single lung ventilation, aorticcross clamping and unclamping, or systemic heparinization. As a result, endovascular repair of BTTAI has emerged as an effective, minimally invasive treatment alternative, especially in patients with severe concomitant injuries, which may be prohibitive to open surgical repair. Recent published studies have shown that endovascular repair of BTTAI is associated with lower morbidity, mortality, stroke, and paraplegia/paraparesis rates, when compared with open surgical repair of BTTAI.

    Blunt thoracic trauma represents a significant portion of trauma admissions to hospitals in the United States. These injuries are encountered by physicians in many specialities such as emergency medicine, pediatrics, general surgery and thoracic surgery. Accurate diagnosis and treatment improves the chances of favorable outcomes and it is desirable for all treating physicians to have current knowledge of all aspects of blunt thoracic trauma. Cardiothoracic surgeons often treat the most severe forms of blunt thoracic injuries and we review the aspects of blunt thoracic trauma that are pertinent to the practicing cardiothoracic surgeon.

    Cardiac injuries are classified as blunt and penetrating injuries. In both the injuries, the major issue is missing the diagnosis and high mortality. Blunt cardiac injuries (BCI) are much more common than penetrating injuries. Aiming at a better understanding of BCI, we searched the literature from January 1847 to January 2012 by using MEDLINE and EMBASE search engines. Using the key word "Blunt Cardiac Injury," we found 1814 articles; out of which 716 articles were relevant. Herein, we review the causes, diagnosis, and management of BCI. In conclusion, traumatic cardiac injury is a major challenge in critical trauma care, but the guidelines are lacking. A high index of suspicion, application of current diagnostic protocols, and prompt and appropriate management is mandatory. PMID:23041686

    Background Traumatic thoracic aortic dissection is uncommon in clinical practice; however, it is associated with high morbidity and mortality. Thoracic aortic dissection is usually caused by sudden deceleration resulting from a traffic accident or fall. Aortic injury after blunt trauma is a critical condition. This study reported the outcomes of endovascular repair of acute traumatic aortic dissection in patients at a district general hospital. Methods In this study, we retrospectively reviewed the clinical data of eight patients with acute traumatic aortic dissection after a blunt trauma who had undergone thoracic endovascular aortic repair (TEVAR) between January 2012 and December 2015 at a district general hospital in Taiwan. Results The median age of the patients was 49±22 years (range, 20–77 years), and 6 of the 8 (75%) patients were men. Five patients were involved in traffic accidents, and 3 patients had fallen from heights. The injury severity score (ISS) of the patients ranged from 17 to 66. In all patients, the aortic injury was located near the origin of the left subclavian artery (LSA). Four patients had seal ostium of subclavian artery, left. None of the patients developed paraplegia or lower extremity ischemia. Moreover, all patients had concomitant injuries, and no patients died postoperatively. Conclusions Endovascular repair is a rapid and minimally invasive therapy for patients with traumatic aortic injury and is associated with favorable technical results. PMID:27293831

    Introduction. Pneumoscrotum is a rare clinical entity. It presents with swollen scrotal sac and sometimes with palpable crepitus. It has many etiologies. One of them is due to blunt trauma of the thoracic cage, causing pneumothorax and/or pneumomediastinum. Case Presentation. We report the case of an 82-year-old male who was transferred to the Emergency Department with signs of respiratory distress after a blunt chest trauma. A CT scan was obtained, and bilateral pneumothoraces with four broken ribs were disclosed. Subcutaneous emphysema expanding from the eyelids to the scrotum was observed, and a chest tube was inserted on the right side with immediate improvement of the vital signs of the patient. Discussion. Pneumoscrotum has three major etiologies: (a) local introduction of air or infection from gas-producing bacteria, (b) pneumoperitoneum, and (c) air accumulation from lungs, mediastinum, or retroperitoneum. These sources account for most of the cases described in the literature. Treatment should be individualized, and surgical consultation should be obtained in all cases. Conclusion. Although pneumoscrotum itself is a benign entity, the process by which air accumulates in the scrotum must be clarified, and treatment must target the primary cause. PMID:23401836

    A traumatic thoracic aortic injury is fatal in the majority of cases. Surviving the aortic injury in addition to the myriad of associated trauma requires comprehensive medical management from many medical services. Balancing these services and coordinating the medical care requires free and open communication between services. Although one might assume a thoracic aortic injury takes precedence over other injuries, an organized plan of care in which the morbidity of the injury as well as the consequences of treatment of each injury helps provide an appropriate “rank order” in the treatment process. A patient with a thoracic aortic injury can be observed for several days while additional injuries are treated, as long as appropriate blood pressure controls are observed. The treatment order for multiple injuries must be reevaluated on a regular basis to adjust for changes in the overall clinical condition. This rank order to treatment and scheduled treatment plan allows for appropriate imaging, evaluation, and coordination of services in preparation for the placement of a thoracic aortic stent graft. The goal of treatment is to reduce the risk of aortic rupture and subsequent fatal hemorrhage. Choosing an open surgical repair versus an endovascular stent graft depends upon physician expertise and clinical status of the patient. In the appropriate clinical setting, endovascular repair of the thoracic aortic injury has become the treatment of choice at the authors' institution in patients with significant operative risks and extensive comorbid injuries. Specific characteristics of the injured aorta also dictate the type of endovascular device required for repair. Case reviews of a patient with blunt trauma and a patient with penetrating trauma used to demonstrate clinical parameters, imaging options, and details of stent graft choice and placement, are presented followed by a review of the literature.

    Purpose. Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft. Methods. Nine men (mean age 29.5 years) were admitted to our institution between January 2003 and January 2006 due to blunt aortic trauma following violent motor vehicle collisions. Plain chest radiography, spiral computed tomography, aortography, and transesophageal echocardiography were used for diagnostic purposes in all cases. All patients were diagnosed with contained extramural thoracic aortic hematomas, secondary to aortic disruption. One patient was also diagnosed with a traumatic thoracic aortic dissection, secondary to blunt trauma. All subjects were poor surgical candidates, due to major injuries such as multiple bone fractures, abdominal hematomas, and pulmonary contusions. All repairs were performed using the EndoFit (LeMaitre Vascular) stent-graft. Results. Complete exclusion of the traumatic aortic disruption and pseudoaneurysm was achieved and verified at intraoperative arteriography and on CT scans, within 10 days of the repair in all patients. In 1 case the deployment of a second cuff was necessary due to a secondary endoleak. In 2 cases the left subclavian artery was occluded to achieve adequate graft fixation. No procedure-related deaths have occurred and no cardiac or peripheral vascular complications were observed within the 12 months (range 8-16 months) follow-up. Conclusions. This is the first time the EndoFit graft has been utilized in the treatment of thoracic aortic disruptions secondary to chest trauma. The repair of such pathologies is technically feasible and early follow-up results are promising.

    The Gerbode defect is characterized by a perimembranous ventricular septal defect between the left ventricle and the right atrium. This intracardiac shunt is a congenital defect but may be iatrogenic after valve surgery or atrioventricular node ablation, may be the result of endocarditis or may be traumatic. It is really rarely encountered as sequelae of non-penetrating heart trauma, and their clinical manifestations may often be unrecognized in the multi-injured patient. However, they are serious complications, and their diagnostic approach is not always feasible. We hereby present a case of a young man with the left ventricle to the right atrium communication after blunt thoracic trauma due to a car accident and concomitant rupture of the thoracic aorta. We present also the case and the ways of treatment according to the international bibliography. PMID:26750699

    Abstract Effective analgesia in the early stages after any major traumatic event remains pivotal to optimal trauma management. For patients with significant thoracic injuries, this is paramount to ensure ongoing efficient respiratory function. The aim of this study was to investigate the use of analgesic modes in the management of patients with a primary thoracic injury and blunt mechanism of injury. By understanding variables that influence the use of varying analgesic modes and influence the development of pulmonary complications, there should be more uniform evidence-based prescription in the future. This retrospective study considered analgesic use in patients admitted after blunt thoracic injuries at one major trauma center over a 2-year period. Pulmonary complications measured included both infective and ventilator-associated failure. Univariate and multivariate analyses were used to identify patient and injury severity characteristics and their association with respiratory complications. A total of 401 cases were reviewed and analyzed: 159 received Patient Controlled Analgesia (PCA), 32 received PCA and epidural analgesia (EA), 6 received EA alone, and 204 received interval-administered analgesia. There were no significant differences in the rates of complication when compared between analgesic modes. Patients who developed pneumonia had significantly increased number of thoracic fractures and underlying organ injury (P < 0.05). Logistic regression analysis highlighted duration of intercostal drain insertion (OR 1.377, P = 0.001) and premorbid cardiac disease (OR 2.624, P = 0.042) and ICU length of stay (OR: 1.146, P < 0.001) as significant predictors of developing pneumonia in this patient group. Examining the different analgesic modes, this study failed to identify a particular analgesic mode that was more effective in preventing pulmonary complications in blunt thoracic injuries. However, variables that may influence usage of different

    Injuries to the thoracic duct are infrequent but may become life-threatening when chylous leakage persists. This report describes 6 patients with such injuries in whom the leakage resolved spontaneously in one, was corrected using microsurgical lymphatic repair or lymphatic-venous anastomosis in two, successfully treated either by ligation of the thoracic duct or insertion of a peritoneovenous shunt in two, and was eventually controlled after bilateral pleurodesis and thoracic duct ligation by insertion of a peritoneo-venous shunt in one. Conventional lymphography is superior to lymphoscintigraphy and is usually required to document disruption of the thoracic duct. PMID:11939572

    Blunt thoracic trauma is a common occurrence in automobile accidents. Acute myocardial infarction (AMI) caused by coronary dissection following blunt thoracic trauma is rare. We report a case of healthy 24-year-old man with a history of blunt thoracic injury with subsequent undetected AMI who died of acute decompensated heart failure 4 days after the insult. The autopsy findings showed a 90% luminal narrowing of the left anterior descending coronary artery by dissecting hematoma, 3 cm in length. The myocardium revealed transmural myocardial infarction affecting apex, most part of left ventricular free wall, and interventricular septum. Both lungs were heavy, wet, and noncrepitant. Histological findings of the infarcted myocardium were consistent with 3-5 days post-AMI. Sections from both lungs revealed massive pulmonary edema, reflecting acute decompensated heart failure following a large AMI secondary to coronary dissection. Blunt thoracic trauma may obscure typical chest pain associated with cardiac ischemia especially in cases with a high tolerance for pain. PMID:26454807

    The detachment or tearing of the retina in the human eye as a result of a collision is a phenomenon that occurs very often. This research is aimed at identifying and understanding the actual dynamic physical mechanisms responsible for traumatic eye injuries accompanying blunt impact, with particular attention to the damage processes that take place at the retina. To this purpose, a numerical and experimental investigation of the dynamic response of the eye during an impact event was performed. Numerical simulation of both tests was performed with IMPETUS-FEA, a general non-linear finite element software which offers NURBS finite element technology for the simulation of large deformation and fracture in materials. Computational results were compared with the experimental results on fresh enucleated porcine eyes impacted with airsoft pellets. The eyes were placed in a container filled with 10 percent ballistic gelatin simulating the fatty tissue surrounding the eye. A miniature pressure transducer was inserted into the eye bulb through the optic nerve in order to measure the pressure of the eye during blunt-projectile impacts. Each test was recorded using a high speed video camera. The ocular injuries observed in the impacted eyes were assessed by an ophthalmologist in order to evaluate the correlation between the pressure measures and the risk of retinal damage.

    Background: Trauma represents a global public health concern with an estimated 5 million deaths annually. Moreover, the incidence of blunt traumatic injuries (BTI) particularly road traffic accidents (RTAs) and workplace-related injuries are rising throughout the world-wide. Objectives: We aimed to review the epidemiology and prevention of BTI, in the Arab Middle East. Materials and Methods: A traditional narrative literature review was carried out using PubMed, MEDLINE and EMBASE search engines. We used the keywords “traumatic injuries”, “blunt” “epidemiology”, “Arab Middle East” between December 1972 and March 2013. Results: The most common mechanisms of BTI in our region are RTAs, falls from height, struck by heavy objects and pedestrian motor vehicle trauma crashes. The rate of RTA and occupational injuries are markedly increased in the region due to rapid industrial development, extreme climatic conditions and unfamiliar working environment. However, lack of reliable information on these unintentional injuries is mainly responsible for the underestimation of this trauma burden. This knowledge deficit shields the extent of the problem from policy makers, leading to continued fatalities. These preventable injuries in turn add to the overall financial burden on the society through loss of productivity and greater need of medical and welfare services. Conclusion: In the Arab Middle East, population-based studies on the incidence, mechanism of injury, prevention and outcome of BTI are not well-documented. Therefore, region-specific BTI studies would strengthen surveillance to better understand the burden of these injuries in the region. PMID:24812453

    2014-01-01

    Intercostal artery pseudoaneurysm is an extremely unusual condition, with less than 10 reported cases to our knowledge. Most of them have been associated with surgical interventions or blunt thoracic trauma. The bleeding risk in this kind of lesions is considerable, the majority of them presenting as haemothorax. We present a case of an intercostal artery pseudoaneurysm detected after a blunt thoracic trauma in a patient with signs of acute bleeding. The identification of a small artery pseudoaneurysm as the cause of haemothorax requires knowledge of this possible aetiology as well as detailed attention to the CT technique. Embolisation is considered to be the first therapeutic method in the management of a ruptured pseudoaneurysm. To reduce the risk of failure, the anatomic features and adjacent vessels providing collateral branches must be studied and embolised if needed, with important attention to collateral blood supply arising from the musculophrenic and anterior intercostal arteries.

    The lethal nature of transmural aortic injuries has remained constant; however, both the diagnostic and therapeutic interventional options have improved. Although aortography is still the "gold standard" against which all other diagnostic modalities are measured, contrast-enhanced spiral thoracic computed tomography has emerged as the diagnostic study that could potentially supplant aortography. The advent of the fast spiral computed tomography scanners offer several advantages, including being less affected by patient motion and volume-averaging artifacts than the earlier generation CT scanners. The operative has broadened from primary repair and interposition prosthetic graft placement (with possible use of shunt or roller vs. centrifugal bypass) to the potential widespread use of endovascular stents. The Eastern Virginia Medical School (EVMS) experience during the first 10-year period (see table below) highlights the majority of patients undergoing interposition prosthetic graft placement. There was no use of shunts during this period. At the midpoint of the second 10-year period (1997-2007), the method of repair is exclusively interposition graft placement. The role of endovascular stent insertion in the management of these injuries is currently being debated. [table: see text] PMID:14649580

    Blunt traumatic cardiac rupture is associated with a high rate of mortality. A review of the computerized trauma registry (1983 to 1988) identified 32 patients with this injury (ages 19 to 65 years; mean age, 39.5 years; 21 men and 11 women). Twenty-one patients (65.6%) were injured in vehicular crashes, 3 (9.4%) in pedestrian accidents, 3 (9.4%) in motorcycle accidents; 3 (9.4%) sustained crush injury; 1 (3.1%) was injured by a fall; and 1 (3.1%) was kicked in the chest by a horse. Anatomic injuries included right atrial rupture (13[40.6%]), left atrial rupture (8 [25%]), right ventricular rupture (10[31.3%]), left ventricular rupture (4[12.5%]), and rupture of two cardiac chambers (3 [9.4%]). Diagnosis was made by thoracotomy in all 20 patients presenting in cardiac arrest. In the remaining 12 patients, the diagnosis was established in seven by emergency left anterolateral thoracotomy and in five by subxyphoid pericardial window. Seven of these 12 patients (58.3%) had clinical cardiac tamponade and significant upper torso cyanosis. The mean Injury Severity Score (ISS), Trauma Score (TS), and Glasgow Coma Scale (GCS) score were 33.8, 13.2, and 14.3, respectively, among survivors and 51.5, 8.3, and 7.0 for nonsurvivors. The overall mortality rate was 81.3% (26 of 32 patients), the only survivors being those presenting with vital signs (6 of 12 patients [50%]). All patients with rupture of two cardiac chambers or with ventricular rupture died. The mortality rate from myocardial rupture is very high. Rapid prehospital transportation, a high index of suspicion, and prompt surgical intervention contribute to survival in these patients. PMID:2256761

    Blunt traumatic infrarenal aortic injuries are unusual, and the formation of a delayed pseudoaneurysm of the aorta is even more rare. In this report, a young woman developed a small intimal flap of the infrarenal aorta after a motor vehicle accident which progressed into a 3 cm pseudoaneurysm after 3 months. Operative repair was successful and the patient recovered. This case illustrates the importance of repeat imaging of small blunt aortic injuries since progression can occur. PMID:27252519

    ehind Armor Blunt Trauma (BABT) is a persistent concern for both the military and civil law enforcement. Although personal protective equipment (PPE), including soft and hard body armor, mitigates penetrating injuries from ballistic threats, the impact generates a backface deformation which creates a high-rate blunt impact to the body and potential internal injury (i.e., BABT). A critical need exists to understand the mechanics of the human response and subsequently evaluate the efficacy of current and proposed PPE in mitigating BABT injury risk. Current human surrogate test platforms lack anatomical fidelity or instrumentation for capturing the dynamic transfer of energy during the event. Therefore, we have developed and tested a Human Surrogate Torso Model (HSTM) composed of biosimulants representing soft tissues and skeleton of the human torso. A matrix of pressure transducers were embedded in the soft tissue and a custom displacement sensor was mounted to the skeletal structure to measure sternum displacement. A series of non-penetrating, high energy ballistic tests were performed with the HSTM. Results indicate that both sternum displacement and internal localized pressure are sensitive to impact energy and location. These data provide a spatial and temporal comparison to the current standard (static clay measurements) and a method for evaluating the applicability of thoracic injury metrics, including the Viscous Criterion, for BABT. The HSTM provides an advanced, biomechanically relevant test platform for determining the thoracic response to dynamic loading events due to non-penetrating ballistic impacts. PMID:22846323

    The objective of the study is to better understand how blunt projectile ballistic parameters and material properties influence the events leading to injuries. The present work focuses on lateral thoracic impacts and follows an experimental approach. The projectiles are made with a soft foam nose assembled with a rigid rear plastic part. The dynamic properties of the foams were first determined using the Split Hopkinson Pressure Bar (SHPB) system. The impact forces on a rigid wall were then measured to provide reference load data. Lastly, shots were made on isolated thoraxes of porcine cadavers to investigate the response in the vicinity of the impact (wall displacements, rib accelerations and strains, rib fractures). Results show that the severity of the response appears to be mainly correlated with the impulse and with the pre-impact momentum. PMID:25951500

    The injury to the thoracic aorta caused by blunt chest trauma is often fatal. This case is 22-year-old male suffering from transection of the thoracic descending aorta caused by traffic accident. He was transported to our emergency room by an ambulance 15 minutes after the accident. Hundred fifty minutes after arrival to the hospital, we were rush to bring him to the operation theater suspecting serious injury of the thoracic organs in association with left hemothorax. The left standard thoracotomy disclosed the injury of the thoracic descending aorta. Simple cross clamp was applied to the thoracic descending aorta distal to the left subclavian artery for 20 minutes. Completely transected aorta was reapproximated using monofilament 3-0 polypropylene sutures with running manner. He tolerated the procedure well without any complication. His postoperative course was uneventful. He was followed up at the orthopedic department for associated hip fracture thereafter. PMID:1942696

    Traumatic rupture of the aorta at the level of the isthmus is a well-recognized injury following blunt chest trauma. By contrast, rupture of the ascending aorta and of the aortic valve in a road traffic accident is rare and does not appear to have been previously reported. The occurrence of such an injury in a 56-year-old man involved in a road traffic accident is reported. The diagnosis was made preoperatively following aortography and successful surgical correction involved aortic valve replacement with resection and grafting of the damaged area of the ascending aorta. The probable mechanisms involved in the production of this unusual injury are discussed. PMID:834060

    Blunt traumatic abdominal aortic dissection is extremely rare and potentially deadly. We present the case of a 62-year-old man involved in a frontal car crash. After emergency undergoing laparotomy for bowel injuries, he was referred to our hospital due to acute ischemia of bilateral lower extremities on day 3 after the trauma. Computed tomography and aortography showed an aortobiiliac dissection with complete occlusion. This injury was successfully treated by endovascular treatment with 'kissing'-technique stent placement, which appears to be a safe, effective, and minimally invasive treatment.

    Displacement patterns of rib fractures (RF) and their association with thoracic coinjuries and outcomes are unknown. This is a retrospective review of adult patients with blunt closed RF who underwent chest CT at a Level I trauma center (2007-2012). Displacement patterns of RF were compared among the three-dimensional planes using CT images. An analysis of receiver operating characteristic (ROC) curves was performed to identify displacements in each plane most strongly associated with chest coinjuries. Univariate analysis was used to find association of displaced RF with hospital course and outcome. There were 1127 RF (245 patients, most in ribs 3-9, 45 per cent displaced). Axial displacement was the most common, with odds ratios 7.20 and 2.13 compared with cranio-caudal, and impaction-separation (along rib axis) movement, respectively. Axial displacement thresholds performed well with hemothorax (2.8 mm, ROC = 0.74), pneumothorax (2.6 mm, ROC = 0.70), hemopneumothorax (3.1 mm, ROC = 0.77), flail chest (3.4 mm, ROC = 0.80), and chest tube placement (2.8 mm, ROC = 0.75). RF displacement was associated with increased days on mechanical ventilation and hospital length of stay. In conclusion, even minimal RF displacement is associated with increased risk of chest coinjuries and chest tube placement, and displacements correlated with increased days on mechanical ventilation and hospital length of stay. Future studies are required to investigate these associations, especially in relationship to the indications for rib plating. PMID:27099054

    Traumatic aortic injury represents 15% of motor vehicle related deaths with death occurring at the scene in 85% of the cases. Aortic disruptions usually occur at the isthmus in a transverse fashion with all three of the aortic layers being involved. Herein, we report the case of a 68-year old man with no prior medical history who was struck by a vehicle while riding his bicycle. The ruptured segment of aorta was resected circumferentially and interrupted horizontal mattress pledgeted prolene sutures were used to ensure full thickness aortic integrity of the proximal and distal aortic segments. The aorta was closed with a single-layer technique using 4/0 prolene suture. There were no postoperative complications and patient was discharged on Day 44. The case here discussed demonstrates a rare presentation of blunt aortic injury. The proximal ascending aorta is an unusual site of transection following blunt trauma with few reports in the literature. We were able to repair the aorta with direct suture, thus avoiding the use of artificial material. PMID:23838337

    Introduction Traumatic thoracic spondyloptosis is caused by high energy trauma and is usually associated with severe neurological deficit. Cases presenting without any neurological deficit can be difficult to diagnose and manage. Case Presentation We reported a four-week spondyloptosis of the ninth thoracic vertebra over the tenth thoracic vertebra, in a 20-year-old male without any neurological deficit. The patient had associated chest injuries. The spine injury was managed surgically with in-situ posterior instrumentation and fusion. The patient tolerated the operation well and postoperatively there was no neurological deterioration or surgical complication. Conclusions Patients presenting with spondyloptosis with no neurological deficit can be managed with in-situ fusion via pedicle screws, especially when presenting late and with minimal kyphosis.

    Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leakage forming a pseudoaneurysm within the hematoma. Pseudoaneurysm arose from the superior gluteal branch of right internal iliac artery, which was successfully angioembolized. The patient was discharged on day 4 of hospitalization with resolving gluteal hematoma. This report highlighted the importance of considering an arterial injury following blunt trauma to the buttocks with subsequent painful swelling. Acknowledgment of this rare injury pattern was necessary to facilitate rapid diagnosis and appropriate treatment. PMID:27578385

    Blunt traumatic rupture of the heart and pericardium, rarely diagnosed preoperatively, carries a high mortality rate. From 1979 to 1989, more than 20,000 patients were admitted to a Level I trauma center. A retrospective review identified 59 patients requiring emergency surgery for this condition. Injuries resulted from vehicular accidents (68%), motorcycle crashes (10%), pedestrians being struck by vehicles (7%), falls (5%), crushing (7%), and being struck by a horse (2%) or crane (2%). Seventeen patients (29%) had isolated rupture of the pericardium; 37 (63%) had ruptures of one or more cardiac chambers. All patients had signs of life at the scene or during transportation, but only 29 (49%) had vital signs on admission: 15 with chamber injury, 12 with pericardial rupture, and two with combined injuries. Diagnosis was established by emergency thoracotomy in the 30 patients who arrived in cardiac arrest. In the remaining 29 patients, diagnosis was made by urgent thoracotomy (41%), by subxiphoid pericardial window (34%), during laparotomy (21%), or by chest radiography (3%). The overall mortality rate was 76% (45 patients), but only 52% for those with vital signs on admission. Rapid transportation and expeditious surgical treatment can save many patients with these injuries. PMID:1994075

    The detachment or tearing of the retina in the human eye as a result of a collision is a phenomenon that occurs very often. Reliable numerical simulations of eye impact can be very useful tools to understand the physical mechanisms responsible for traumatic eye injuries accompanying blunt impact. The complexity and variability of the physical and mechanical properties of the biological materials, the lack of agreement on their related experimental data as well as the unsuitability of specific numerical codes and models are only some of the difficulties when dealing with this matter. All these challenging issues must be solved to obtain accurate numerical analyses involving dynamic behavior of biological soft tissues. To this purpose, a numerical and experimental investigation of the dynamic response of the eye during an impact event was performed. Numerical simulations were performed with IMPETUS-AFEA, a new general non-linear finite element (FE) software which offers non uniform rational B-splines (NURBS) FE technology for the simulation of large deformation and fracture in materials. IMPETUS code was selected in order to solve hourglass and locking problems typical of nearly incompressible materials like eye tissues. Computational results were compared with the experimental results on fresh enucleated porcine eyes impacted with airsoft pellets.

    BACKGROUND: The role of video-assisted Thoracoscopic Surgery (VATS) is still being defined in the management of thoracic trauma. We report our trauma cases managed by VATS and review the role of VATS in the management of thoracic trauma. MATERIALS AND METHODS: All the trauma patients who underwent VATS from 2000 to 2007 at Cedars-Sinai Medical Center were retrospectively studied. RESULTS: Twenty-three trauma patients underwent 25 cases of VATS. The most common indication for VATS was retained haemothorax. Thoracotomy was avoided in 21 patients. VATS failed in two cases. On an average VATS was performed on trauma day seven (range 1-26) and the length of hospital stay was 20 days (range 3-58). There was no mortality. VATS was performed in an emergency (day 1-2), or in the early (day 2-7) or late (after day 7) phases of trauma. CONCLUSION: VATS can be performed safely for the management of thoracic traumas. VATS can be performed before or after thoracotomy and at any stage of trauma. The use of VATS in trauma has a trimodal distribution (emergent, early, late), each with different indications.

    2016-07-01

    We present a case of traumatic intercostal pulmonary herniation in an 11-year-old boy after blunt trauma to the chest, without associated chest wall disruption or pneumothorax. This condition is especially uncommon in children, with only 5 previously reported cases and most occurring after penetrating chest trauma. To date, there are no reports in literature describing traumatic intercostal lung herniation at the diaphragmatic junction with a closed chest cavity in a child. The number of traumatic lung herniation diagnoses may be expanded by a more liberal use of computed tomography when serious injury is suspected. Computed tomography and advanced imaging should be considered in pediatric trauma patients presenting with concern for intrathoracic injury that may not be seen on plain film. Traumatic blunt intrathoracic and intra-abdominal injuries in the pediatric population that are within proximity of diaphragmatic insertion should be thoroughly evaluated to rule out diaphragmatic injury. As in our case, invasive surgical intervention such as thoracoscopy may be necessary. PMID:27380604

  17. A thoracic mechanism of mild traumatic brain injury due to blast pressure waves.

    PubMed

    Courtney, A C; Courtney, M W

    2009-01-01

    The mechanisms by which blast pressure waves cause mild-to-moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to the brain via a thoracic mechanism. The hypothesis that the blast pressure wave reaches the brain via a thoracic mechanism is considered in light of ballistic and blast pressure wave research. Ballistic pressure waves, caused by penetrating ballistic projectiles or ballistic impacts to body armor, can only reach the brain via an internal mechanism and have been shown to cause cerebral effects. Similar effects have been documented when a blast pressure wave has been applied to the whole body or focused on the thorax in animal models. While vagotomy reduces apnea and bradycardia due to ballistic or blast pressure waves, it does not eliminate neural damage in the brain, suggesting that the pressure wave directly affects the brain cells via a thoracic mechanism. An experiment is proposed which isolates the thoracic mechanism from cranial mechanisms of mTBI due to blast wave exposure. Results have implications for evaluating risk of mTBI due to blast exposure and for developing effective protection. PMID:18829180

    Background Airway clearance is frequently needed by patients suffering from blunt chest wall trauma. High Frequency Chest Wall Oscillation (HFCWO) has been shown to be effective in helping to clear secretions from the lungs of patients with cystic fibrosis, bronchiectasis, asthma, primary ciliary dyskinesia, emphysema, COPD, and many others. Chest wall trauma patients are at increased risk for development of pulmonary complications related to airway clearance. These patients frequently have chest tubes, drains, catheters, etc. which could become dislodged during HFCWO. This prospective observational study was conducted to determine if HFCWO treatment, as provided by The Vest™ Airway Clearance System (Hill-Rom, Saint Paul, MN), was safe and well tolerated by these patients. Methods Twenty-five blunt thoracic trauma patients were entered into the study. These patients were consented. Each patient was prescribed 2, 15 minute HFCWO treatments per day using The Vest® Airway Clearance System (Hill-Rom, Inc., St Paul, MN). The Vest® system was set to a frequency of 10–12 Hz and a pressure of 2–3 (arbitrary unit). Physiological parameters were measured before, during, and after treatment. Patients were free to refuse or terminate a treatment early for any reason. Results No chest tubes, lines, drains or catheters were dislodged as a result of treatment. One patient with flail chest had a chest tube placed after one treatment due to increasing serous effusion. No treatments were missed and continued without further incident. Post treatment survey showed 76% experienced mild or no pain and more productive cough. Thirty days after discharge there were no deaths or hospital re-admissions. Conclusion This study suggests that HFCWO treatment is safe for trauma patients with lung and chest wall injuries. These findings support further work to demonstrate the airway clearance benefits of HFCWO treatment. PMID:18837992

    Background Coronary artery dissection is a rare complication of blunt thoracic trauma which can become rapidly lethal necessitating prompt diagnosis and treatment. Most reported cases of coronary artery injury, including dissection, involve the left anterior descending coronary artery, given its anatomical location in relation to the impact. Description of case A 72-year-old male, who was involved in a vehicular accident, sustained blunt thoracic trauma which resulted in isolated right coronary artery dissection and acute myocardial infarction. The culprit lesion was found in coronary angiography in the proximal right coronary artery and was successfully repaired with percutaneous coronary intervention and one drug-eluting stent placement. Conclusion Traumatic dissection of coronary arteries must be suspected in blunt thoracic trauma. It can be treated with interventional management and results in a fairly good prognosis.

    The incidence of cardiac rupture following blunt trauma is rare, occurring in 0.3%-0.5% of all blunt trauma patients. It can be fatal at the trauma scene, and is frequently missed in the emergency room setting. The severity of a cardiac trauma is based on the mechanism and degree of the force applied. The objective of this study was to report the case of a 32-year-old male patient who was involved in a motor vehicle collision and presented to the emergency room with signs of hypovolemic shock. The patient was found to have severe chest trauma associated with massive hemothorax requiring immediate intervention. The patient had an emergent thoracotomy revealing a right atrial injury. Repair of the atrial injury reversed the state of shock. The patient was discharged after 35 days of hospitalization in good condition. PMID:27054650

    Subcutaneous facial emphysema is a well-known consequence of oral and maxillofacial traumatic injury. In some rare cases, the subcutaneous air collection could spread through the retropharyngeal and paralatero-cervical spaces, reaching the mediastinum. This clinical entity is known as pneumomediastinum and represents a severe and, sometimes, life-threatening condition. Other reported causes of pneumomediastinum are esophageal and tracheal traumatic or iatrogenic rupture. Finally, the so-called spontaneous pneumomediastinum is caused by a sudden increase in alveolar pressure and is usually seen in young men. We present two cases of pneumomediastinum as a consequence of unusual traumatic damage of orofacial tissues, followed by repeated sneezing and Valsalva maneuver. PMID:26134477

    2016-09-01

    Veterinary pathologists commonly encounter lesions of blunt trauma. The development of lesions is affected by the object's mass, velocity, size, shape, and angle of impact and by the plasticity and mobility of the impacted organ. Scrape, impact, and pattern abrasions cause localized epidermal loss and sometimes broken hairs and implanted foreign material. Contusions are best identified after reflecting the skin, and must be differentiated from coagulopathies and livor mortis. Lacerations-traumatic tissue tears-may have irregular margins, bridging by more resilient tissue, deviation of the wound tail, crushed hairs, and unilateral abrasion. Hanging or choking can cause circumferential cervical abrasions, contusions and rupture of hairs, hyoid bone fractures, and congestion of the head. Other special forms of blunt trauma include fractured nails, pressure sores, and dog bites. Ocular blunt trauma causes extraocular and intraocular hemorrhages, proptosis, or retinal detachment. The thoracic viscera are relatively protected from blunt trauma but may develop hemorrhages in intercostal muscles, rib fractures, pulmonary or cardiac contusions or lacerations with subsequent hemothorax, pneumothorax, or cardiac arrhythmia. The abdominal wall is resilient and moveable, yet the liver and spleen are susceptible to traumatic laceration or rupture. Whereas extravasation of blood can occur after death, evidence of vital injury includes leukocyte infiltration, erythrophagocytosis, hemosiderin, reparative lesions of fibroblast proliferation, myocyte regeneration in muscle, and callus formation in bone. Understanding these processes aids in the diagnosis of blunt force trauma including estimation of the age of resulting injuries. PMID:27381403

    Background: This study was to determine the extent and outcome of childhood chest injury in Nigeria, and to compare results with that of other literatures. Patients and Methods: A Prospective study of all children under 18 years of age with chest trauma in two tertiary hospitals in Southern Nigeria from January 2012 to December 2014 was reviewed. The aetiology, type, associated injury, mechanism, treatment and outcome were evaluated. The patients were followed up in the clinic. The data were analysed using SPSS version 20.0 with a significant P < 0.05. Results: Thirty-one patients (12.1%) under 18 years of age of 256 chest trauma patients were managed in the thoracic units. The mean age was 9.78 ± 6.77 years and 27 (87.1%) were male. The aetiology in 13 was from falls, 10 from automobile crashes, 3 from gunshots, 4 from stabbing and 1 from abuse. The highest peak of chest injury was on Saturday of the week and April of the year. The pleural collections are as follows: 15 (71.4%) was haemothorax, 4 (19.1%) pneumothorax, 2 (9.5%) haemopneumothorax and 18 patients had lung contusion in combination or alone with the pleural collections. Seven patients who presented >12-h versus 2 who presented <12-h and 6 of children between 0 and 9 years versus 3 at 10-18 years of age had empyema thoracis (P value not significant). One death was recorded. Conclusion: Chest trauma in children is still not common, and blunt chest injury from falls and automobile accidents are more common than penetrating chest injury. Treatment with tube thoracostomy is the major management modality with empyema thoracis as the most common complication. PMID:26612123

    A 20-year-old man was admitted to the emergency department after falling 15 m onto the roof of a car and landing on his back. Imaging by computed tomography (CT) showed delayed perfusion of the right kidney and no excretion of contrast from that kidney on delayed images. Angiography confirmed a localized intimal dissection in the right main renal artery. We inserted a balloon-expandable stent using a transfemoral approach to successfully repair the dissection. At 4 year follow-up, Doppler ultrasound of the right renal artery and renal scintigraphy demonstrated preserved function of the right kidney. Our findings support endovascular stenting as a safe, effective and efficient treatment for blunt renal artery injury.

    Hepatic trauma is a common cause for admissions in the Emergency Room. Currently, non-surgical management is the standard treatment in haemodynamically stable patients with a success rate of around 85 to 98%. This haemodynamic stability is the most important factor in selecting the appropriate patient. Adjuncts in non-surgical management are angioembolisation, image-guided drainage and endoscopic retrograde cholangiopancreatography. Failure in non-surgical management is relatively rare but potentially fatal, and needs to be recognised and aggressively treated as early as possible. The main cause of failure in non-surgical management is persistent haemorrhage. The aim of this paper is to describe current evidence and guidelines that support non-surgical management of liver injuries in blunt trauma. PMID:27036671

    We describe a case of a 33-year-old skydiver who presented to the emergency department after a traumatic landing following a parachuting episode. He initially presented with right knee pain secondary to a tibial plateau fracture. There were no neurological symptoms or signs at the initial assessment. While he was still in the emergency department, he suddenly developed headache and left-sided hemiplegia. An urgent work-up showed right middle cerebral artery thrombosis with right internal carotid thrombosis and dissection. We have discussed some possible mechanism of injury in skydiving that may have predisposed to the occurrence of cervical dissection in our patient. PMID:23559649

    Objectives: We present our experience of endovascular surgery for traumatic aortic injury and the results of our procedures. Materials and Methods: From January 2009 to December 2013, we performed endovascular repairs of traumatic thoracic aortic injury on 5 male patients 16–75 years old (mean, 50.8), two of whom were young. Three of the patients had multiple organ injuries. The mean interval time to the operation is 22.0 hours (range, 10–36). All patients underwent endovascular repair with heparinization. The isthmus regions were seen in three cases and all of them were needed left subclavian artery (LSA) coverage. In the two young patients, the deployed stent graft was 22 mm (22.2% oversizing for diameter of aorta) and 26 mm (36.8% oversizing), respectively. Results: The procedures were successful in all patients, with no early mortality, paraplegia or stroke. During 3–63 months (mean, 30.8) follow-up period, no one experienced stent graft-related complications. One patient with LSA coverage experienced arm ischemia but the symptom improved with time. Conclusion: Endovascular surgery for traumatic thoracic aortic injury can be performed safely with low mortality or morbidity even in young small aorta. Accumulation of clinical experience and evaluation of long-term outcomes are necessary. PMID:25298833

    OBJECT Computed tomography angiography (CTA) is frequently used to examine patients for blunt cerebrovascular injury (BCVI) after cranial trauma, but the pediatric population at risk for BCVI is poorly defined. Although CTA is effective for BCVI screening in adults, the increased lifetime risk for malignant tumors associated with this screening modality warrants efforts to reduce its use in children. The authors' objective was to evaluate the incidence of BCVI diagnosed by CTA in a pediatric patient cohort and to create a prediction model to identify children at high risk for BCVI. METHODS Demographic, clinical, and radiographic data were collected retrospectively for pediatric patients who underwent CTA during examination for traumatic cranial injury from 2003 through 2013. The primary outcome was injury to the carotid or vertebral artery diagnosed by CTA. RESULTS The authors identified 234 patients (mean age 8.3 years, range 0.04-17 years, 150 [64%] boys) who underwent CTA screening for BCVI. Of these, 24 (10.3%) had a focal neurological deficit, and 153 (65.4%) had intracranial hemorrhage on a head CTA. Thirty-seven BCVIs were observed in 36 patients (15.4%), and 16 patients (6.8%) died. Multivariate regression analysis identified fracture through the carotid canal, petrous temporal bone fracture, Glasgow Coma Scale (GCS) score of < 8, focal neurological deficit, and stroke on initial CT scan as independent risk factors for BCVI. A prediction model for identifying children at high risk for BCVI was created. A score of ≤ 2 yielded a 7.9% probability of BCVI and a score of ≥ 3 a risk of 39.3% for BCVI. CONCLUSIONS For cranial trauma in children, fracture of the petrous temporal bone or through the carotid canal, focal neurological deficit, stroke, and a GCS score of < 8 are independent risk factors for BCVI.

    Outcome after traumatic brain injury (TBI) in the elderly has not been fully elucidated. The present retrospective observational study investigates the age-dependent outcome of patients suffering from severe isolated TBI with regard to operative and non-operative treatment. Data were prospectively collected in the TraumaRegister DGU. Anonymous datasets of 8629 patients with isolated severe blunt TBI (AISHead≥3, AISBody≤1) documented from 2002 to 2011 were analysed. Patients were grouped according to age: 1-17, 18-59, 60-69, 70-79 and ≥80 years. Cranial fractures (44.8%) and subdural haematomas (42.6%) were the most common TBIs. Independent from the type of TBI the group of patients with operative treatment declined with rising age. Subgroup analysis of patients with critical TBI (AISHead=5) revealed standardised mortality ratios (SMRs) of 0.81 (95% CI 0.75-0.87) in case of operative treatment (n=1201) and 1.13 (95% CI 1.09-1.18) in case of non-operative treatment (n=1096). All age groups ≥60 years showed significantly reduced SMRs in case of operative treatment. Across all age groups the group of patients with low/moderate disability according to the GOS (4 or 5 points) was higher in case of operative treatment. Results of this retrospective observational study have to be interpreted cautiously. However, good outcome after TBI with severe space-occupying haemorrhage is more frequent in patients with operative treatment across all age groups. Age alone should not be the reason for limited care or denial of operative intervention. PMID:25799473

    While elderly patients account for only 10-12% of all trauma victims, they consume 25% of trauma-related health care resources, with higher rates of mortality and complication. Presently described is the case of an elderly patient who presented to the emergency department (ED) following mild thoracic trauma, with previous history of gastric pull-up surgery. The patient had consulted another facility 48 hours earlier and was prescribed analgesia and x-ray follow-up for a mechanical fall and pain in the lower rib cage. At arrival, the patient complained of increasing dyspnea and pain at the right hemithorax. X-ray showed right hemithorax effusion, and contrast computed tomography (CT) demonstrated a large amount of contrast filling the pleural space and a relatively small point of gastric pull-up rupture in the stomach. The patient was referred to the cardiothoracic unit, but was unresponsive upon arrival and died. The aim of the present report was to raise the index of clinical suspicion of traumatic rupture of the gastric pull-up following traumatic chest injury, and to affirm that contrast CT should be the gold standard for diagnosis.

    Introduction a Meckel’s diverticulum is one of the most common congenital anomalies of the digestive tract. The reported lifetime complication rate is 4%, mostly due to hemorrhage, obstruction, perforation or inflammation. A symptomatic Meckel’s diverticulum due to rupture after blunt abdominal trauma is very rare. We believe this case report is the first reporting a rupture of a Meckel’s diverticulum after a low velocity blunt abdominal trauma and outlining the importance of a thorough and complete examination of the patient after blunt abdominal trauma. Presentation of case a 17-year-old male presented with abdominal pain after blunt abdominal trauma during a soccer game. Physical examination showed signs of peritonitis in all quadrants of the abdomen. During admission the patient deteriorated with decreasing blood pressure and raising pulse rate. A CT-scan showed free abdominal fluid. Our patient was scheduled for an emergent laparotomy where a perforated Meckel’s diverticulum with fecal spill was found. A segmental ileal resection was performed. Post-operative, patient developed a pneumonia and also intra-abdominal abscesses treated with percutaneous drainage. After an admission period of 17-days the patient was discharged. Conclusion perforation of a Meckel’s diverticulum is rarely suspected as a cause of acute deterioration following blunt abdominal trauma. This case shows the importance of awareness of this kind of injury especially in male patients. PMID:26701844

    Patients in traffic accidents are usually presented with pain and bleeding due to fractures or soft tissue injury. On some occasions, more severe complications may be triggered by the trauma. A review of the published English language literature reveals no survival case once the traumatic mediastinal hematoma is ruptured. In our case, a 54-year-old man suffering motorcycle accident was admitted to emergency department. Computed tomography scan revealed subdural hematoma combined with posterior mediastinal hematoma. The patient was saved and discharged with a satisfactory outcome. Here we hope to share our treatment experience in dealing with the patient with severe multiple trauma. PMID:27033275

    Background: There have been rare cases of traumatic cervical spondyloptosis without neurological compromise. We report another case and provide a review of the literature, with a focus on appropriate management. Case Description: A 60-year-old male rode his bicycle into a stationary semi-truck. He reported initial bilateral upper extremity paresthesias that resolved. Imaging demonstrated C7 on T1 spondyloptosis. Traction did not achieve reduction and a halo was applied. Subsequently, he underwent posterior decompression C6-T1, reduction via bilateral complete facetectomies at C7, and fixation from C4 to T2 fixation. Afterward, an anterior C7-T1 fixation occurred, where exposure was performed through a midline sternotomy. Postoperatively, he woke up with baseline motor and sensory examination in his extremities. He did exhibit voice hoarseness due to paralysis of the left vocal cords. He was discharged home 3 days after surgery. At 6 months follow-up, there was a progressive improvement of the left vocal cords to slight paresis; dynamic X-rays demonstrated no instability with good fusion progression. Conclusion: Traumatic cervical spondyloptosis without neurological compromise is a rare and challenging scenario. There is a concern for neurologic compromise with preoperative traction, but if specific posterior elements are fractured, the spinal canal may be wide enough where the concern for disc migration is minimal. For patients who have not been reduced preoperatively, a posterior approach with initial decompression to widen the canal, before reduction, appears safe. This scheme may avoid an initial anterior approach for decompression, necessitating a 3-stage procedure if circumferential stabilization is pursued. PMID:27274411

    Hemothorax is common in elderly patients following blunt chest trauma. Traditionally, tube thoracostomy is the first choice for managing this complication. The goal of this study was to determine the benefits of this approach in elderly patients with and without an initial tube thoracostomy. Seventy-eight patients aged >65 years with blunt chest trauma and stable vital signs were included. All of them had more than 300 mL of hemothorax, indicating that a tube thoracostomy was necessary. The basic demographic data and clinical outcomes of patients with hemothorax who underwent direct video-assisted thoracoscopic surgery without a tube thoracostomy were compared with those who received an initial tube thoracostomy. Patients who did not receive a thoracostomy had lower posttrauma infection rates (28.6% versus 56.3%, P = 0.061) and a significantly shorter length of stay in the intensive care unit (3.13 versus 8.27, P = 0.029) and in the hospital (15.93 versus 23.17, P = 0.01) compared with those who received a thoracostomy. The clinical outcomes in the patients who received direct VATS were more favorable compared with those of the patients who did not receive direct VATS. PMID:27190987

    Although diaphragmatic injuries caused by blunt or penetrating trauma are rare entities, they are the most commonly misdiagnosed injuries in trauma patients and occur in approximately 3–7% of all abdominal or thoracic traumas. Acute pancreatitis secondary to late presenting diaphragmatic hernia is very rare. Here we present two separate cases: one with acute bowel obstruction and the other with acute pancreatitis secondary to late onset traumatic diaphragmatic hernia (three and twenty-eight years after chest trauma, resp.).

    Blunt injury to the chest can affect any one or all components of the chest wall and thoracic cavity. The clinical presentation of patients with blunt chest trauma varies widely and ranges from minor reports of pain to florid shock. Traumatic tricuspid valve regurgitation is a rare cardiovascular complication of blunt chest trauma. Tricuspid valve regurgitation is usually begotten by disorders that cause the right ventricle to enlarge. Diagnosis is made by physical examination findings and is confirmed by echocardiography. We report two cases of severe tricuspid regurgitation secondary to the rupture of the chordae tendineae of the anterior leaflet following non-penetrating chest trauma. Both patients had uneventful postoperative courses. PMID:23323081

    Most traumatic diaphragmatic tears are located centrally or radially and may be amenable to repair by direct suturing or suturing with a surgical patch. However, diaphragmatic tears, such as those immediately adjacent to the costal margin, are uncommon. We describe how we repaired this type of tear using a needle loop retractor to pass a 2-0 braided suture through the chest wall on both sides of the rib to suture the torn diaphragm to the chest wall. Our technique is more physiologically and anatomically consistent than previously reported techniques. We have termed this technique the "lifting-up method", which we believe to be an easy and useful technique for repairing traumatic diaphragmatic injuries with no seam allowance. PMID:26391998

    A cardio-embolic stroke as a sequela of remote blunt chest trauma is a rare clinical presentation. Blunt chest trauma can cause various acute cardiac complications like arrhythmias, cardiac contusion etc. However, delayed consequences such as left ventricular thrombus resulting in thromboembolic phenomena are reported infrequently. A 30-year-old healthy man presented to an outside facility with transient neurological deficits. An MRI brain showed lesions suggestive of embolic etiology. A trans-thoracic echocardiogram (TTE) showed a 1.5 × 1.5 cm mass present in the left ventricular (LV) apex. Patient was transferred to our institution for cardiac surgery evaluation. On detailed questioning, he reported an incident of blunt chest trauma during a martial arts exhibition fight that took place 2 years back. Given this history, a cardiac catheterization was done, which showed 30% stenosis in mid-left anterior descending artery (LAD) without any other significant obstructive lesion. A trans-esophageal echocardiogram (TEE) showed akinesis of the LV apex and confirmed TTE finding of a mass, consistent with an apical thrombus. Surgery was deferred and patient was started on anticoagulation. A cardiac MRI done 2 weeks later showed evidence of apical infarction in the LAD territory. LAD is the most commonly affected coronary vessel by blunt traumatic injuries, likely due to its vulnerable anatomical position on the anterior aspect of the heart. A variety of mechanisms including intimal tear, rupture and spasm have been implicated in the pathogenesis of myocardial infarction after blunt chest trauma. PMID:24023477

    Blunt injury to the heart ranges from contusion to disruption. This report comprises 14 patients seen during a 6-year period with cardiac rupture secondary to blunt trauma. Eight patients were injured in automobile accidents, two patients were injured in auto-pedestrian accidents, two were kicked in the chest by ungulates, and two sustained falls. Cardiac tamponade was suspected in ten patients. Five patients presented with prehospital cardiac arrest or arrested shortly after arrival. All underwent emergency department thoracotomy without survival. Two patients expired in the operating room during attempted cardiac repair; both had significant extracardiac injury. Seven patients survived, three had right atrial injuries, three had right ventricular injuries, and one had a left atrial injury. Cardiopulmonary bypass was not required for repair of the surviving patients. There were no significant complications from the cardiac repair. The history of significant force dispersed over a relatively small area of the precordium as in a kicking injury from an animal or steering wheel impact should alert the physician to possible cardiac rupture. Cardiac rupture should be considered in patients who present with signs of cardiac tamponade or persistent thoracic bleeding after blunt trauma. PMID:6708151

    We report the case of a patient who suffered major trauma following a motorcycle accident that resulted in multiple fractures, bilateral hemopneumothorax, pulmonary contusions, and an isthmic rupture of the aorta with a pseudoaneurysm compressing the descending aorta. This compression was responsible for distal hypotension and low flow, leading to acute renal insufficiency and massive rhabdomyolysis. Due to the critical clinical status of the patient, which prevented any type of open thoracic surgery, endovascular treatment was performed. An initial stent-graft permitted alleviation of the compression and the re-establishment of normal hemodynamic conditions, but its low position did not allow sufficient coverage of the rupture. A second stent-graft permitted total exclusion of the pseudoaneurysm while preserving the patency of the left subclavian artery.

    Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

    In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients. PMID:26147725

    Our aim is to present midterm results after endovascular repair of acute and chronic blunt aortic injury. Between December 1999 and December 2005, 13 patients were endovascularly treated for blunt aortic injury. Ten patients, 8 men and 2 women, mean age 38.7 years, were treated for acute traumatic injury in the isthmus region of thoracic aorta. Stent-graftings were performed between the fifth hour and the sixth day after injury. Three patients (all males; mean age, 66 years; range, 59-71 years) were treated due to the presence of symptoms of chronic posttraumatic pseudoaneurysm of the thoracic aorta (mean time after injury, 29.4 years, range, 28-32). Fifteen stent-grafts were implanted in 13 patients. In the group with acute aortic injury one patient died due to failure of endovascular technique. Lower leg paraparesis appeared in one patient; the other eight patients were regularly followed up (1-72 months; mean, 35.6 months), without complications. In the group with posttraumatic pseudoaneurysms all three patients are alive. One patient suffered postoperatively from upper arm claudication, which was treated by carotidosubclavian bypass. We conclude that the endoluminal technique can be used successfully in the acute repair of aortic trauma and its consequences. Midterm results are satisfactory, with a low incidence of neurologic complications.

    Thoracic venous injuries are predominantly attributed to traumatic and iatrogenic causes. Gunshot wounds and knife stabbings make up the vast majority of penetrating trauma whereas motor vehicle collisions are the leading cause of blunt trauma to the chest. Iatrogenic injuries, mostly from central venous catheter complications are being described in growing detail. Although these injuries are rare, they pose a diagnostic challenge as their clinical presentation does not substantially differ from that of arterial injury. Furthermore, the highly lethal nature of some of these injuries provides limited literature for review and probably underestimates their true incidence. The widespread use of multi-detector computed tomography (MDCT) has increased the detection rate of these lesions in hemodynamically stable patients that survive the initial traumatic event. In this article, we will discuss and illustrate various causes of injury to each vein and their supporting CT findings while briefly discussing management. The available literature will be reviewed for penetrating, blunt, and iatrogenic injuries to the vena cava, innominate, subclavian, axillary, azygos, and pulmonary veins. PMID:26965007

    In closed chest trauma, bronchial rupture is an unusual but potentially serious complication, with an associated mortality rate of 30%. Recent decades have seen an increase in incidence parallel to greater use of transport. Eighty percent of injuries are located 2.5 cm from the carina. Diagnosis is based on clinical signs, imaging and bronchoscopy. Subcutaneous emphysema and respiratory insufficiency are the most common findings. Images show the presence of pneumothorax, pneumomediastinum or both. Bronchoscopy is the diagnostic method of choice and must be performed early. Treatment consists of reestablishing anatomical continuity of the tracheobronchial tree by surgical repair if the lesion affects more than a third of the circumference and/or pneumothorax is not resolved after two chest drainages. This type of injury should be recognized and treated early, both to restore lung function and to prevent associated complications caused by delay. However, initial findings are seldom specific, requiring the physician to display a high degree of suspicion and explaining why diagnosis often comes late. PMID:11171438

    Blunt chest traumatic coronary artery dissection is an uncommon cause of atherosclerotic and non-atherosclerotic Acute Myocardial Infarction (AMI). Injuries of the coronary artery after blunt chest trauma are caused by different mechanisms such as vascular spasm, dissection and intimal tear or rupture of an existing thrombus formation. Chest pain might be masked by other injuries in patients with multiple traumas in car accident. Present case report is on a 37-year-old male without any specific past medical history who reported to the emergency department of a hospital with chest discomfort and was discharged with the impression of chest wall pain. After three days he experienced severe chest pain and he was admitted with the impression of acute coronary syndrome and underwent coronary angiography which showed Left Anterior Descending (LAD) artery dissection. The possibility of injury of the coronary artery should be kept in mind after blunt trauma to the chest. This condition is sometimes underdiagnosed. Its diagnosis may be difficult because chest pain can be interpreted as being secondary to chest wall contusion or it may be overshadowed by other injuries. Coronary dissection diagnosis after chest trauma requires clinical suspicion and systematic evaluation. Electrocardiography (ECG) should be done for every patient with thoracic trauma as the clinical findings may be misleading. PMID:27504338

    This study assessed the moderation of blood alcohol level (BAL) and American Indian race on survival of patients with violent traumatic brain injury (TBI). An initial logistic regression model indicated that those who were American Indian and insured had higher odds of survival and those with higher injury severity scores and low-medium BAL were less likely to survive. A second logistic regression model including a relationship between American Indians and BAL found that American Indians had a higher odds of survival which tripled when they have no BAL. Low-medium and high BAL were associated with less likelihood of survival among White patients. PMID:26963822

    Traumatic injuries involving the thorax can be superficial, necessitating only routine wound care, or they may extend to deeper tissue planes and disrupt structures immediately vital to respiratory and cardiac function. Diagnostic imaging, especially ultrasound, should be considered part of a comprehensive examination, both at admission and during follow-up. Horses generally respond well to diligent monitoring, intervention for complications, and appropriate medical or surgical care after sustaining traumatic wounds of the thorax.

    Blunt thoracic aortic injury (BTAI) remains a common cause of death following blunt mechanisms of trauma. Among patients who survive to reach hospital care, significant advances in diagnosis and treatment afford previously unattainable survival. The Society for Vascular Surgery (SVS) guidelines provide current best-evidence suggestions for treatment of BTAI. However, several key areas of controversy regarding optimal BTAI care remain. These include the refinement of selection criteria, timing for treatment and the need for long-term follow-up data. In addition, the advent of the Aortic Trauma Foundation (ATF) represents an important development in collaborative research in this field. PMID:25868973

    Intrapericardial rupture of the superior vena cava resulting from blunt thoracic trauma is a rare and life-threatening condition that has to be ruled out in the presence of signs of cardiac tamponade and a history of blunt thoracic trauma. We report the case of undiagnosed superior vena cava laceration caused by a high-speed road traffic accident in a 25 year-old patient revealed by cardiac tamponade. We highlight the need of urgent surgical exploration in all patients whose condition is unstable in the setting of blunt thoracic trauma regardless of imaging conclusions. PMID:27106431

    In German-speaking countries, most serious thoracic injuries are attributable to the impact of blunt force; they are the second most frequent result of injury after head injury in polytrauma patients with multiple injuries. Almost one in every three polytraumatized patients with significant chest injury develops acute lung failure, and one in every four, acute circulatory failure. The acute circulatory arrest following serious chest injury involves a high mortality rate, and in most cases it reflects a tension pneumothorax, cardiac tamponade, or hemorrhagic shock resulting from injury to the heart or one of the large vessels close to it. Brisk drainage of tension pneumothorax and adequate volume restoration are therefore particularly important in resuscitation of multiply traumatized patients, as are rapid resuscitative thoracotomy to allow direct heart massage, drainage of pericardial tamponade, and control of hemorrhage. However the probability of survival described in the literature is very low for patients sustaining severe chest trauma with acute cardiac arrest. The case report presented here describes a female polytrauma patient who suffered an acute cardiac arrest following cardiac tamponade after admission in the emergency department and who survived without neurological deficits after an emergency thoracotomy. Selections from the topical literature can help the treating physician in the emergency department in making decisions on whether an emergency thoracotomy is indicated after a blunt chest injury and on the procedure itself.

    Blunt, nonpenetrating injuries of the thoracic aorta are uncommon and associated with a high mortality rate within the first hour. Aortic injury is missed in 1-2% of patients that survive to hospital, and a chronic thoracic aortic aneurysm may subsequently form. We present a case in which a chronic thoracic aortic aneurysm was diagnosed 29 years following a significant motor vehicle accident. We discuss the epidemiology, presentation, and management of this uncommon consequence of blunt, nonpenetrating aortic injury. Our case illustrates an important clinical lesson; a past medical history of trauma should not be overlooked at any patient assessment. PMID:26351610

    Introduction : The nonoperative management of traumatic spleen injuries is the modality of choice in patients with blunt abdominal trauma and hemodynamic stability. However, there are still questions about the treatment indication in some groups of patients, as well as its follow-up. Aim: Update knowledge about the spleen injury. Method : Was performed review of the literature on the nonoperative management of blunt injuries of the spleen in databases: Cochrane Library, Medline and SciELO. Were evaluated articles in English and Portuguese, between 1955 and 2014, using the headings "splenic injury, nonoperative management and blunt abdominal trauma". Results : Were selected 35 articles. Most of them were recommendation grade B and C. Conclusion : The spleen traumatic injuries are frequent and its nonoperative management is a worldwide trend. The available literature does not explain all aspects on treatment. The authors developed a systematization of care based on the best available scientific evidence to better treat this condition.

    A 21-year-old male suffered blunt trauma from a motor vehicle accident causing thoracic aorta tear. The smallest available stent graft was deployed. Definitive repair was later performed using a 22 × 22 × 116 mm Talent Thoracic Stent Graft. The postoperative course was uneventful. Seventeen months later, he presented with dizziness, chest pain, acute renal failure, malignant hypertension, and troponin elevation. Computed tomography (CT) angiogram and transesophageal echocardiogram did not reveal any dissection, stent stenosis or collapse. Cardiac catheterization showed normal coronary arteries but a 117 mm Hg gradient across the stent graft. Iatrogenic coarctation of the aorta was confirmed with a second measurement during arch angiogram. A Palmaz stent was deployed over the distal end of the previous stent graft with complete resolution of symptoms and gradual normalization of kidney function. This case report demonstrates a need for wider availability and selecting appropriate stent graft in treating traumatic aortic injuries in young patients. It is the first case report of the inability of current imaging modalities in confirming stent collapse. Pressure gradient is a useful tool in confirming stent collapse when clinical scenario does not match CT findings. PMID:25637574

    Traumatic pulmonary pseudocyst constitutes an uncommon, though well recognized, manifestation of closed chest trauma. It is usually encountered in young patients, whose compliant chest wall permits the transmission of great compressive forces to the lung parenchyma and the laceration of the latter. Traumatic pulmonary pseudocyst is usually detected during the imaging evaluation of multi-injured patients with the use of computed tomography, as it is often not apparent in the initial supine anteroposterior chest radiographs. We present 5 cases of trauma patients, in whom we detected the presence of multiple traumatic pulmonary pseudocysts during the imaging evaluation of blunt chest trauma with the use of computed tomography.

    Diaphragmatic hernias that are diagnosed in adulthood may be traumatic or congenital in nature. Therefore, respiratory specialists need to be aware of the presentation of patients with these conditions. In this report, we describe a case series of patients with congenital and traumatic diaphragmatic hernias and highlight a varied range of their presentations. Abnormalities were noted in the thorax on the chest radiographs, but it was unclear as to the nature of the anomaly. The findings on thoracic ultrasound conducted by a pulmonologist helped to direct appropriate investigations avoiding unnecessary interventions. Instead of pleural effusions, consolidation or collapse, thoracic computed tomography demonstrated diaphragmatic hernias which were managed either conservatively or by surgery. There is increasing evidence that pulmonary specialists should be trained in thoracic ultrasonography to identify pleural pathology as well as safely conducting pleural-based interventions.

    Several theories have been proposed to explain the Blunt Traumatic Aortic Rupture (BTAR) because different mechanical forces act on the aorta, at anatomically susceptible sites, including shearing, torsion and stretching, but the origin, transduction and relative importance of these forces remain uncertain. We report a case of a 74-year-old man injured by a kick to the abdomen. After 2 days he felt chest pain paroxysm and weakness in his left leg. The patient was admitted to an emergency care department where he experienced sudden and severe hemodynamic deterioration, dying rapidly. The autopsy, performed 3 days later, showed haemorragic infarction of hypogastric subcutaneous tissues and revealed an extended dissecting aneurysm of the thoracic aorta with following haemopericardium. In our case we considered that a low energy compression to the abdomen, in presence of underlying atherosclerosis, caused aortic dissection rather than rupture and then the 48h time span after the traumatic event and the cardiac tamponade was enough to complete the aortic retrograde dissection. We finally emphasise the importance of the careful surveillance of any trauma close to the abdomen in view of initially unpredictable, as well as eventful injuries. The finding of early signs of neointima formation in thoracoabdominal portions of aortic dissection strongly supported our interpretation. The forensic interest of this case is correlated to the voluntary character of the inflicted injury. The culprit was thus charged with manslaughter. PMID:18849182

    Deaths due to blunt force trauma to the head as a result of assault are some of the most common cases encountered by the practicing forensic pathologist. Previous studies have shown inflicting injury to the head region is one of the most effective methods of murder. The important factors that determine severity of trauma include the type of weapon used, type and site of skull fracture, intracranial haemorrhage and severity of brain injury. The aim of this study was to determine the characteristics of blunt force trauma to the skull produced by different instruments. Nine adult monkeys (Macaca fascicularis) skulls were used as models. Commonly found blunt objects comprising of Warrington hammer, hockey stick and open face helmet were used in this study. A machine calibrated force generator was used to hold the blunt object in place and to hit the skulls at forces of 12.5N and 25N. Resultant traumatic effects and fractures (linear, depressed, basilar, comminuted, and distastic) were analyzed according to type of blunt object used; surface area of contact and absolute force (N/cm(2)) delivered. Results showed that all investigated instruments were capable of producing similar injuries. The severity of trauma was not related to the surface area of contact with the blunt objects. However, only high absolute forces produced comminuted fractures. These findings were observational, as the samples were too small for statistical conclusions. PMID:24763233

    Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    Trauma laparotomy after blunt abdominal trauma is conventionally indicated for patients with features of hemodynamic instability and peritonitis to achieve control of hemorrhage and control of spillage. In addition, surgery is clearly indicated for the repair of posttraumatic diaphragmatic injury with herniation. Some other indications for laparotomy have been presented and discussed. Five patients with blunt abdominal injury who underwent laparotomy for nonroutine indications have been presented. These patients were hemodynamically stable and had no overt signs of peritonitis. Three patients had solid organ (spleen, kidney) infarction due to posttraumatic occlusion of the blood supply. One patient had mesenteric tear with internal herniation of bowel loops causing intestinal obstruction. One patient underwent surgery for traumatic abdominal wall hernia. In addition to standard indications for surgery in blunt abdominal trauma, laparotomy may be needed for vascular thrombosis of end arteries supplying solid organs, internal or external herniation through a mesenteric tear or anterior abdominal wall musculature, respectively.

    Acute thoracic symptoms are common among adults visiting emergency departments in the United States. Adults with these symptoms constitute a large burden on the overall resources used in the emergency department. The wide range of possible causes can make a definitive diagnosis challenging, even after clinical evaluation and initial laboratory testing. In addition to radiography and computed tomography, thoracic ultrasonography (US) is an alternative imaging modality that can be readily performed in real time at the patient's bedside to help diagnose many thoracic diseases manifesting acutely and in the trauma setting. Advantages of US include availability, relatively low cost, and lack of ionizing radiation. Emergency thoracic US consists of two main parts, lung and pleura US and focused cardiac US, which are closely related. Acoustic mismatches among aerated lungs, pleura, chest wall, and pathologic conditions produce artifacts useful for diagnosis of pneumothorax and pulmonary edema and help in detection of subpleural, pleural, and chest wall pathologic conditions such as pneumonia, pleural effusion, and fractures. Visual assessment of cardiac contractility and detection of right ventricular dilatation and pericardial effusion at focused cardiac US are critical in patients presenting with acute dyspnea and trauma. Additional US examinations of the inferior vena cava for noninvasive volume assessment and of the groin areas for detection of deep venous thrombosis are often performed at the same time. This multiorgan US approach can provide valuable information for emergency treatment of both traumatic and nontraumatic thoracic diseases involving the lungs, pleura, chest wall, heart, and vascular system.

    This is a retrospective analysis of 50 postraumatic aortic rupture (1968-1996, 39 males, mean age: 34.5). Group A is composed of 35 patients with an acute aortic rupture and a prompt diagnosis. Group B includes 13 patients with a chronic rupture. All patients from group A had a severe politraumatism with abdominal, cranial, extremities or hip fractures. Mediastinal thickening with or without hemothorax indicated an angiography or a transesophageal echocardiography lately. In group A, 36 patients have been operated on urgently (12-24 hours); cardiopulmonary bypass was performed on 20 patients; an aorto-aortical bypass was done in 27 cases and a direct suture in the remaining 9. In group B, cardiopulmonary bypass was performed on 9 patients; a aorto-aortical bypass was done in 11 cases and a direct suture in 2. Overall hospital mortality was 16%; 19% in group A and 7.6% in group B. Ischemic paraplejia appeared in 5 patients (10%), all from group A. No false aneurysm developed after 4.5 years of follow-up (3-135 months) in the 38 survivors. The usefulness of transesophageal echocardiography, the importance of medular protection and the utility of several interventionist radiologic techniques are discussed. PMID:9053930

    Objectives The public health implications of regional variation in incidence and outcome of severe traumatic injury remain to be analyzed. The objective of this study was to determine whether the incidence and outcome associated with severe traumatic injury differs across geographic regions of North America. Methods A prospective, observational study was conducted of the Resuscitation Outcomes Consortium of all patients in 9 North American sites (6 US and 3 Canadian) sustaining severe traumatic injury from April 1, 2006 to March 31, 2007 followed to hospital discharge. Eligible patients were assessed by organized emergency medical services, and had field-based physiologic criteria including systolic blood pressure ≤90 mm Hg, Glasgow Coma Scale score ≤12, respiratory rate <10 or >29 per minute, advanced airway procedure, or traumatic death in the field. Census data were used to determine rates adjusted for age and sex. The main outcome measures were incidence rate, mortality rate, case fatality rate, and survival to discharge for patients sustaining severe traumatic injury assessed by EMS. Results The total catchment population of 20.5 million yielded 7080 cases of severe traumatic injury. Median age was 36 years and 67% were male. The median incidence of EMS-assessed severe traumatic injury per 100,000 population across sites was 37.4 (interquartile range [IQR] = 24.6 – 69.6); survival ranged from 39.8% to 80.8%, with a median of 64.5% (IQR = 55.5–78.4). About 942 cases were pronounced dead at the scene and 5857 patients were transported to hospital; 4477 (63.2%) were discharged alive. The median incidence of severe trauma due to a blunt mechanism, transported to hospital, was 25.8 (IQR = 13.1–44.3); survival ranged from 52.6% to 87.3%, with a median of 78.0% (IQR = 68.4–83.5). The median incidence of severe penetrating trauma, transported to hospital, was 2.6 (IQR = 1.5–10.4); survival ranged from 37.5% to 84.7%, with a median of 67.5% (IQR = 54.1

    Thoracic outlet syndrome (TOS) is a well-known disorder, but its definition has been disputed. TOS is differentiated into five distinct disorders: arterial vascular, venous vascular, traumatic neurovascular, true neurologic (TN-TOS), and nonspecific TOS. TN-TOS is caused by compression of the lower plexus (T1>C8 roots and/or lower trunk) by a fibrous band. The most frequent presenting symptoms are insidious-onset atrophy and weakness of the intrinsic hand muscles, predominantly in the thenar eminence and radial digital flexors. Numbness and sensory loss are usually present, mainly in the ulnar forearm, although severe pain or pain/paresthesia proximal to the elbow can occur; however, sensory symptoms or signs can be absent in some patients. Nerve conduction studies are pathognomonic and show the loss or severe attenuation of the sensory nerve action potential (SNAP) of the medial antebrachial cutaneous nerve. Additionally, they show a severely depressed median compound muscle action potential (CMAP) and, subsequently, a depressed ulnar CMAP and SNAP. TN-TOS is a rare disorder, although its incidence may be higher than previously believed. Hirayama disease is an important differential diagnosis. Nonspecific TOS, which is mainly diagnosed by provocative maneuvers, corresponds to the classical concept of TOS. However, this concept is now challenged and the existence of nonspecific TOS is doubted. PMID:25475030

    Two hypotheses were investigated: (1) helical computed tomography (CT) of the chest on victims of decelerating trauma can yield a diagnosis of, or "rule out," a traumatic rupture of the aorta (TRA) without the need for an aortogram; and (2) selective delay of aortic repair can be safely accomplished through a medical management protocol. Screening helical CT examinations were done on 6169 victims of blunt thoracic trauma; 47 were found to have TRA; in 8, indirect but nondiagnostic findings not clarified by an aortogram led to surgical exploration. The sensitivity of helical CT was higher than that of aortograms, and a "normal" helical CT scan was never associated with a proved TRA. It is estimated that the use of helical CT has resulted in at least a 40% to 50% decrease in the need for aortograms, in addition to yielding rapid, noninvasive valuable information about other injuries. Drugs (beta-blockers +/- vasodilators) to decrease the stress in the aortic wall were used in 93 patients when the diagnosis was suspected and were continued as necessary through the evaluation, stabilization, and until the aorta was cross-clamped at operation. Elective, delayed operation was done between 2 days and 25 months in 15 patients who were deemed to be excessive risks for emergency aortic repair; there were 2 deaths (13. 3%). Eleven patients never had aortic repair. No patient maintained on this protocol, whether repaired emergently, electively, or not at all, developed free rupture of the periaortic hematoma and death from TRA. PMID:9841764

    The assessment of a case of blunt abdominal trauma can be complicated by many factors, and the resultant inaccurate or delayed diagnoses have contributed to the unacceptable mortality for this type of injury. Recently several useful diagnostic techniques have been developed that, if applied intelligently, may be instrumental in decreasing the high mortality among patients who present with ambiguous abdominal signs after sustaining blunt trauma. Although hematologic investigation and routine radiography have facilitated detection of intraperitoneal injury, peritoneal lavage has become the single most helpful aid. Scanning procedures are sometimes useful in recognizing splenic and hepatic defects especially; these may be confirmed or clarified by angiography. Although ultrasonography may be no more valuable than scintigraphy in outlining splenic and hepatic abnormalities, it is an important technique, especially in the diagnosis of retroperitoneal masses of traumatic origin. Laparoscopy also may be helpful in investigation if surgeons become more familiar with the procedure. Images FIG. 1 FIG. 2 FIG. 3 FIG. 4 PMID:608158

    Traumatic diaphragmatic injury (TDI) is relatively rare condition, and is associated with high rates of morbidity and mortality. TDI usually results from blunt trauma and penetrating trauma. The majority causes of blunt TDI are victims of motor vehicle accidents. The incidence rates of TDI is unknown because of it can be overlooked if it is unsuspected with non-specific radiological and clinical findings. The mortality rates associated with blunt and penetrating TDI are affected by the severity of concurrent organ injuries. The diagnoses of TDI are frequently missed in the post-traumatic assessment because of non-specific symptoms or physical findings. When the site of trauma is in the abdomen, there will be high rate of an intra-abdominal organ injury. Furthermore, when the site of trauma is in the chest, there will be the abdominal organ injury in 50%.Surgical operation should be performed as soon as possible for concomitant injuries. Diaphragmatic repair can be performed using laparotomy, thoracotomy, or both approaches. Primary suture of the diaphragm can be performed in the majority of TDI patients. The outcome of post TDI depends on concurrent organ injury. In case of emergency, it is important to take an appropriate diagnosis and treatment for any concomitant injuries. PMID:26197916

    Closed-globe traumatic cataract is not uncommon in males in the pediatric age group. However, there is a relative paucity of literature on isolated posterior lens capsule rupture associated with closed-globe traumatic cataract. We report a case of a 6-year-old boy who presented with white cataract 1 day after blunt trauma to the forehead associated with posterior capsular rupture that was detected by B-scan ultrasonography preoperatively. No stigmata of trauma outside the posterior capsule could be detected by slit-lamp exam, funduscopy, and optical coherence tomography. Phacoemulsification with posterior chamber intraocular lens implant was performed 24 hours after trauma, with the patient achieving 6/6 visual acuity 1 week and 6 months after surgery. Our case is unique, being the youngest (amblyogenic age) to be reported, with prompt surgical intervention, and with no signs of trauma outside the posterior capsule. PMID:25506201

    A 25-year-old woman was admitted to our hospital after being involved in a high-speed motorcycle accident. Computed tomography angiography revealed a blunt traumatic aortic injury of the lesser curvature of the distal aortic arch accompanied by splintered fractures of the seventh thoracic vertebra and left clavicle. If the pseudoaneurysm had been treated with open surgical repair, then arch replacement under cardiopulmonary bypass, which was considered to be too invasive, would have been necessary. Therefore, thoracic endovascular aortic repair (TEVAR) was preferred as a first-line treatment to prevent pulmonary complications and hemorrhaging. Because the proximal landing zone for TEVAR was insufficient, we used a modified (fenestrated) commercially available endograft to preserve the branches of the aortic arch. Postoperative computed tomography scans confirmed that the pseudoaneurysm had been excluded without the endoleaks, and the aortic arch branches were patent. The patient's postoperative course was uneventful, and she was discharged from the hospital to have surgery for a vertebral fracture on postoperative day 6. PMID:24184496

    Objectives Traumatic brain injury results in significant morbidity and mortality and is associated with infectious complications, particularly pneumonia. However, whether traumatic brain injury directly impacts the host response to pneumonia is unknown. The objective of this study was to determine the nature of the relationship between traumatic brain injury and the prevalence of pneumonia in trauma patients and investigate the mechanism of this relationship using a murine model of traumatic brain injury with pneumonia. Design Data from the National Trauma Data Bank and a murine model of traumatic brain injury with postinjury pneumonia. Setting Academic medical centers in Cincinnati, OH, and Boston, MA. Patients/Subjects Trauma patients in the National Trauma Data Bank with a hospital length of stay greater than 2 days, age of at least 18 years at admission, and a blunt mechanism of injury. Subjects were female ICR mice 8–10 weeks old. Interventions Administration of a substance P receptor antagonist in mice. Measurements and Main Results Pneumonia rates were measured in trauma patients before and after risk adjustment using propensity scoring. In addition, survival and pulmonary inflammation were measured in mice undergoing traumatic brain injury with or without pneumonia. After risk adjustment, we found that traumatic brain injury patients had significantly lower rates of pneumonia compared to blunt trauma patients without traumatic brain injury. A murine model of traumatic brain injury reproduced these clinical findings with mice subjected to traumatic brain injury demonstrating increased bacterial clearance and survival after induction of pneumonia. To determine the mechanisms responsible for this improvement, the substance P receptor was blocked in mice after traumatic brain injury. This treatment abrogated the traumatic brain injury–associated increases in bacterial clearance and survival. Conclusions The data demonstrate that patients with traumatic

    A 41-year-old motocross rider sustained blunt trauma to the chest following a collision with another rider. He was initially hypoxic and was given oxygen with a non-rebreather mask. He complained of chest pain. A prehospital extended focused assessment with sonography in trauma (eFAST) scan was negative for pneumothorax, but demonstrated a hypokinetic left ventricle. An electrocardiogram (ECG) in the emergency department confirmed anterior myocardial infarction, found to be due to a traumatic left anterior descending coronary artery dissection. This case highlights a rare but life-threatening cause of hypoxia in blunt chest trauma. PMID:21495831

    This review aims to answer the most common questions in routine surgical practice during the first 48 h of blunt chest trauma (BCT) management. Two authors identified relevant manuscripts published since January 1994 to January 2014. Using preferred reporting items for systematic reviews and meta-analyses statement, they focused on the surgical management of BCT, excluded both child and vascular injuries and selected 80 studies. Tension pneumothorax should be promptly diagnosed and treated by needle decompression closely followed with chest tube insertion (Grade D). All traumatic pneumothoraces are considered for chest tube insertion. However, observation is possible for selected patients with small unilateral pneumothoraces without respiratory disease or need for positive pressure ventilation (Grade C). Symptomatic traumatic haemothoraces or haemothoraces >500 ml should be treated by chest tube insertion (Grade D). Occult pneumothoraces and occult haemothoraces are managed by observation with daily chest X-rays (Grades B and C). Periprocedural antibiotics are used to prevent chest-tube-related infectious complications (Grade B). No sign of life at the initial assessment and cardiopulmonary resuscitation duration >10 min are considered as contraindications of Emergency Department Thoracotomy (Grade C). Damage Control Thoracotomy is performed for either massive air leakage or refractive shock or ongoing bleeding enhanced by chest tube output >1500 ml initially or >200 ml/h for 3 h (Grade D). In the case of haemodynamically stable patients, early video-assisted thoracic surgery is performed for retained haemothoraces (Grade B). Fixation of flail chest can be considered if mechanical ventilation for 48 h is probably required (Grade B). Fixation of sternal fractures is performed for displaced fractures with overlap or comminution, intractable pain or respiratory insufficiency (Grade D). Lung herniation, traumatic diaphragmatic rupture and pericardial rupture are life

    The relative benefits of conservative or surgical treatment in thoracic spinal trauma are still controversial. Owing to its anatomic relations, thoracic spinal trauma is specific regarding neurologic prognosis, the high incidence of associated injuries, and surgical management. Over a 30-month period, 49 patients sustained thoracic spinal trauma with neurologic impairment. The authors review population characteristics, associated injuries, and surgical management, and underline the high incidence of associated injuries, in particular, blunt chest trauma. In their opinion, early spinal decompression has no indication in complete paraplegia. Concerning partial paraplegia, early surgery may enhance neurologic recovery. Nevertheless, they suggest three main criteria in deciding whether or not to perform surgery early: the existence of residual spinal compression, the degree of neurologic impairment, and the presence of potential hemorrhagic lesions or blunt chest trauma, especially pulmonary contusion.

    Seventy-seven patients who had sustained multisystem trauma, including severe blunt chest injury, were prospectively evaluated to assess the frequency of associated traumatic myocardial injury. Traumatic injury to either the right or left ventricle was defined by the presence of discrete abnormalities of wall motion on electrocardiographically gated cardiac scintigraphy in patients without a clinical history of heart disease. Forty-two patients (55%) (Group 1) had focal abnormalities of wall motion; 27 involved the right ventricle, 7 the left ventricle, 7 were biventricular, and 1 involved only the septum. Both the right and left ventricular ejection fractions were significantly lower (31 +/- 11% and 47 +/- 14%, respectively) than those in the 35 traumatized patients without wall motion abnormalities on scintigraphy (Group 2) (49 +/- 8% and 58 +/- 11%, respectively). Repeat scintigraphic examination in 32 Group 1 patients at a time remote from initial injury showed improvement or resolution of previously defined focal wall motion abnormalities in 27 of 32 patients (84%). The electrocardiogram and serum enzyme tests were insensitive indexes of traumatic myocardial injury when defined by the scintigraphic abnormalities. Thus, severe blunt chest trauma results in a higher frequency of traumatic myocardial injury than heretofore recognized, and frequently involves the anteriorly situated right ventricle.

    Traumatic injuries of the diaphragm remain an entity of difficult diagnosis despite having been recognised early in the history of surgery, especially when it comes to blunt trauma and injuries of the right diaphragm. We report the case of a patient with blunt trauma with right diaphragmatic rupture that required urgent surgical treatment for hepatothorax and iatrogenic severe liver injury. Blunt trauma can cause substantial diaphragmatic rupture. It must have a high index of suspicion for diaphragmatic injury in patients, victims of vehicle collisions, mainly if they have suffered frontal impacts and/or side precipitates in patients with severe thoracoabdominal trauma. The diagnosis can be performed clinically and confirmation should be radiological. The general measures for the management of multiple trauma patients must be applied. Surgery at the time of diagnosis should restore continuity. PMID:21244704

    Aortic angiography is widely considered the 'gold standard' for the diagnosis of traumatic thoracic aortic injury. Unfortunately, thoracic aortic angiography has many disadvantages: the technique is invasive but, more importantly, it is not routinely available in all hospitals, necessitating transfer of critically ill patients. Contrast-enhancement helical computerised tomography (CEHCT) of the thorax is rapidly becoming available, especially in more district general hospitals, and has been shown to be as sensitive and specific in detecting aortic trauma as angiography. This technique has the advantage of being non-invasive and is able to demonstrate injuries other than thoracic aortic disruption. We present four cases of traumatic thoracic disruption initially diagnosed using CEHCT in whom surgical repair was performed on the basis of the CEHCT findings. The surgical findings of aortic injury were correlated with CEHCT features. Images Figure 1 Figure 2 PMID:11212440

    ABSTRACT Blunt cerebrovascular injury (BCVI) is usually caused by neck trauma that predominantly occurs in high-impact injuries. BCVI may occur due to damage to both the vertebral and carotid arteries, and may be fatal in the absence of appropriate treatment and early diagnosis. Here, we describe a case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery by a direct blunt external force in a 52-year-old man. Initially, there was no effect on consciousness, but 6 hours later loss of consciousness occurred due to traumatic dissection of the carotid artery that resulted in a cerebral infarction. Brain edema was so extensive that decompression by emergency craniectomy and internal decompression were performed by a neurosurgeon, but with no effect, and the patient died on day 7. This is a rare case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery. The case suggests that cervical vascular injury should be considered in a patient with a blunt neck trauma and that additional imaging should be performed. PMID:26412898

Nine months before, he had a road traffic accident with a minor thoracic trauma. Three days after surgery, the patient was readmitted for a tension hydrothorax due to the herniation and the perforation of the stomach into the left pleural cavity. Such a delayed presentation of a traumatic diaphragmatic rupture remains uncommon. The peroperative ventilatory factors involved in the development of the hernia are discussed. PMID:8572411

    The diagnosis of thoracic outlet syndrome was once debated in the world of vascular surgery. Today, it is more understood and surprisingly less infrequent than once thought. Thoracic outlet syndrome (TOS) is composed of three types: neurogenic, venous, and arterial. Each type is in distinction to the others when considering patient presentation and diagnosis. Remarkable advances have been made in surgical approach, physical therapy, and rehabilitation of these patients. Dedicated centers of excellence with multidisciplinary teams have been developed and continue to lead the way in future research. PMID:25140278

    The growing popularity of nonoperative treatment of children with splenic injuries has seduced some physicians into a false sense of security regarding care of the injured child. Although it has been established that hemodynamically stable children with splenic, hepatic, and even renal injuries can safely be treated "expectantly," this concept cannot be applied indiscriminately. Accurate diagnosis and effective care of the child with blunt abdominal trauma is an exercise of clinical precision that demands attention to detail and thorough evaluation. This review addresses this process in light of recent advances in diagnostic imaging and in consideration of recent reports analyzing different protocols for therapeutic decision making.

    Injury to the solid abdominal organs-liver, spleen, kidney, and pancreas-is one of the most common injury patterns in pediatric blunt trauma. Pediatric trauma centers are becoming increasingly successful in managing these injuries without operative intervention. Well-validated guidelines have been established for liver and spleen injury management, and operative intervention is reserved for patients who show evidence of active bleeding after resuscitation. No such guidelines yet exist for the management of traumatic injury of the kidney or pancreas. Exploratory laparotomy remains the treatment of choice in patients suffering hemodynamic collapse, but interventional radiologic or endoscopic procedures are increasingly used to manage all but the most devastating solid organ injuries.

    OBJECTIVE Isolated transverse and spinous process fractures (TPFx and SPFx) in the thoracic and/or lumbar region have been deemed clinically insignificant in the adult population. This same rule is often applied to the pediatric population; however, little evidence exists in this younger group. The goal of this study was to describe the clinical, radiographic, and long-term data on isolated TPFx and SPFx in an exclusively pediatric population. METHODS A retrospective chart review at Monroe Carell Jr. Children's Hospital at Vanderbilt University identified 82 pediatric patients with isolated TPFx and/or SPFx following a traumatic event between January 2000 and December 2013. Patient demographic information, presenting symptoms, radiographic characteristics, and follow-up data were collected. Follow-up was used to determine the outcome (presence of neurological deficits) of such injuries via complete physical examination and, when available, radiographic evidence. RESULTS In the 82 identified patients, the mean age was 15.5 ± 3.1 years (mean is expressed ± SD throughout), with 72 injuries (87.8%) resulting from a motor vehicle, motorcycle, or all-terrain vehicle accident. There was a mean of 1.7 ± 1.0 fractured vertebral levels involved and a mean of 1.8 ± 1.1 fractures was identified per patient. Seventy-one patients (86.6%) needed bedside pain control, 7 (8.5%) were prescribed a brace, and 4 patients (4.9%) received a collar. Physical therapy was recommended for 12 patients (14.6%). A total of 84.1% had follow-up, and the mean length of follow-up was 19 ± 37 months. No patients had true neurological deficits at presentation or follow-up as a result of their isolated fractures, whereas 95.1% had other associated system injuries. CONCLUSIONS These data shows that there is no appreciable long-term complication associated with isolated thoracic and/or lumbar TPFx and/or SPFx in an exclusively pediatric population. Because these fractures are, however, associated

    Introduction: Pneumothorax (PTX) occurs commonly in trauma patients and is confirmed by examination and radiography. Thoracic ultrasound (VIS) has been suggested as an alternative method for rapidly diagnosing PTX when X-ray is unavailable as in rural, military, or space flight settings; however, its accuracy and specificity are not known. Methods: We evaluated the accuracy of thoracic U/S detection of PTX compared to radiography in stable, emergency patients with a high suspicion of PTX at a Level-l trauma center over a 6-month period. Following University and NASA Institutional Review Board approval, informed consent was obtained from patients with penetrating or blunt chest trauma, or with a history consistent with PTX. Whenever possible, the presence or absence of the " lung sliding" sign or the "comet tail" artifact were determined by U/S in both hemithoraces by residents instructed in thoracic U/S before standard radiologic verification of PTX. Results were recorded on data sheets for comparison to standard radiography. Results: Thoracic VIS had a 94% sensitivity; two PTX could not be reliably diagnosed due to subcutaneous air; the true negative rate was 100%. In one patient, the VIS exam was positive while X ray did not confirm PTX; a follow-up film 1 hour later demonstrated a small PTX. The average time for bilateral thoracic VIS examination was 2 to 3 minutes. Conclusions: Thoracic ultrasound reliably diagnoses pneumothorax. Presence of the "lung sliding" sign conclusively excludes pneumothorax. Expansion of the FAST examination to include the thorax should be investigated.

    Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13%) following blunt injury and 20 (87%) after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury. PMID:23723618

    Traumatic ventricular septal defect (VSD) resulting from chest trauma, either penetrating or blunt, is a relatively rare occurrence. Herein, we describe the case of a previously healthy 26-year-old man who presented with congestive heart failure, which was secondary to a large traumatic VSD following violent blunt chest trauma. The traumatic VSD was initially closed percutaneously using an Amplatzer atrial septal defect occluder. Post-device closure, however, the patient developed severe intravascular hemolysis refractory to medical treatment. The patient subsequently underwent surgical removal of the Amplatzer device, with concomitant VSD patch closure. PMID:27357435

    Single port thoracic surgery, reduced port surgery and needlescopic surgery attract attention as one of the minimally invasive surgery in thoracic surgery recently. Single port thoracic surgery was advocated by Rocco in 2004, it was reported usefulness of single port thoracic surgery for primary spontaneous pneumothorax. The surgical procedure as single (or reduced) port thoracic surgery is roughly divided into the following. One is operated with instruments inserted from the single extended incision, and the other is operated with instruments punctured without extending incision. It is not generally complicated procedures in single port thoracic surgery. Primary spontaneous pneumothorax and biopsy for lung and pleura are considered the surgical indication for single (or reduced) port surgery. It is revealed that single port surgery for primary spontaneous pneumothorax is less invasive than conventional surgery. Single port and reduced port thoracic surgery will spread furthermore in the future. PMID:27440029

    For the last 20 years, nonoperative management (NOM) of blunt hepatic trauma (BHT) has been the initial policy whenever this is possible (80% of cases), i.e., in all cases where the hemodynamic status does not demand emergency laparotomy. NOM relies upon the coexistence of three highly effective treatment modalities: radiology with contrast-enhanced computerized tomography (CT) and hepatic arterial embolization, intensive care surveillance, and finally delayed surgery (DS). DS is not a failure of NOM management but rather an integral part of the surgical strategy. When imposed by hemodynamic instability, the immediate surgical option has seen its effectiveness transformed by development of the concept of abbreviated (damage control) laparotomy and wide application of the method of perihepatic packing (PHP). The effectiveness of these two conservative and cautious strategies for initial management is evidenced by current experience, but the management of secondary events that may arise with the most severe grades of injury must be both rapid and effective.

    A 23-year-old man was admitted for a closed head injury following a fall from a height of 5 meters from a ladder. Because of a C-7 burst fracture, a halo and halo vest were applied approximately 9 hours following the fall. Approximately 21 hours after the accident, the patient complained of diplopia. On neuro-ophthalmology evaluation, a unilateral internuclear ophthalmoplegia was noted. MRI of the brain, performed 3 days after application of the halo and vest, showed a small infarct at the posterior aspect of the inferior midbrain, slightly left of midline. At 9.5 weeks there was 90% improvement of the internuclear ophthalmoplegia noted. Of the reported cases in the medical literature of traumatic internuclear ophthalmoplegia, 30 (83.33%) cases were male and 6 (16.67%) were female. The mean age was 31.7. 54% of the cases were bilateral; 46% unilateral.

    OBJECTIVE: The aim of this study was to analyze chest CT scans of patients with thoracic textiloma. METHODS: This was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. RESULTS: The majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). CONCLUSIONS: It is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

    Actinomycosis is a rare condition which, in the thoracic localisation, can mimic cancer or tuberculosis. We report a series of three case of thoracic actinomycosis treated in the Ibn Sina University Thoracic Surgery Unit in Rabat, Morocco. CASE N degrees 1: This 45-year-old patient presented a tumefaction on the left anterior aspect of the chest. Physical examination identified a parietal mass with fistulisation to the skin. Radiography demonstrated a left pulmonary mass. Transparietal puncture led to the pathological diagnosis of actinomycosis. The patient was given medical treatment and improved clinically and radiographically. CASE N degrees 2: This 68-year-old patient presented repeated episodes of hemoptysis. The chest x-ray revealed atelectasia of the middle lobe and bronchial fibroscopy demonstrated the presence of a bud in the middle lobar bronchus. Biopsies were negative. The patient underwent surgery and the histology examination of the operative specimen revealed pulmonary actinomycosis. The patient recovered well clinically and radiographically with antibiotic therapy. CASE N degrees 3: This 56-year-old patient presented cough and hemoptysis. Physical examination revealed a left condensation and destruction of the left lung was noted on the chest x-ray. Left pleuropulmonectomy was performed. Histological analysis of the surgical specimen identified associated Aspergillus and Actinomyces. The outcome was favorable with medical treatment. The purpose of this work was to recall the radiological, clinical, histological, therapeutic, outcome aspects of this condition and to relate the problems of differential diagnosis when can suggest other diseases.

    Primary blast-induced traumatic brain injury (bTBI) is a prevalent battlefield injury in recent conflicts, yet biomechanical mechanisms of bTBI remain unclear. Elucidating specific biomechanical mechanisms is essential to developing animal models for testing candidate therapies and for improving protective equipment. Three hypothetical mechanisms of primary bTBI have received the most attention. Because translational and rotational head accelerations are primary contributors to TBI from non-penetrating blunt force head trauma, the acceleration hypothesis suggests that blast-induced head accelerations may cause bTBI. The hypothesis of direct cranial transmission suggests that a pressure transient traverses the skull into the brain and directly injures brain tissue. The thoracic hypothesis of bTBI suggests that some combination of a pressure transient reaching the brain via the thorax and a vagally mediated reflex result in bTBI. These three mechanisms may not be mutually exclusive, and quantifying exposure thresholds (for blasts of a given duration) is essential for determining which mechanisms may be contributing for a level of blast exposure. Progress has been hindered by experimental designs, which do not effectively expose animal models to a single mechanism and by over-reliance on poorly validated computational models. The path forward should be predictive validation of computational models by quantitative confirmation with blast experiments in animal models, human cadavers, and biofidelic human surrogates over a range of relevant blast magnitudes and durations coupled with experimental designs, which isolate a single injury mechanism.

    Although traumatic brain injury (TBI) is frequently encountered in veterinary practice in companion animals, livestock and horses, inflicted head injury is a common method of euthanasia in domestic livestock, and malicious head trauma can lead to forensic investigation, the pathology of TBI has generally received little attention in the veterinary literature. This review highlights the pathology and pathogenesis of cerebral lesions produced by blunt, non-missile and penetrating, missile head injuries as an aid to the more accurate diagnosis of neurotrauma cases. If more cases of TBI in animals that result in fatality or euthanasia are subjected to rigorous neuropathological examination, this will lead to a better understanding of the nature and development of brain lesions in these species, rather than extrapolating data from human studies.

  1. Mechanisms and Clinical Management of Ventricular Arrhythmias following Blunt Chest Trauma

    2016-01-01

    Nonpenetrating, blunt chest trauma is a serious medical condition with varied clinical presentations and implications. This can be the result of a dense projectile during competitive and recreational sports but may also include other etiologies such as motor vehicle accidents or traumatic falls. In this setting, the manifestation of ventricular arrhythmias has been observed both acutely and chronically. This is based on two entirely separate mechanisms and etiologies requiring different treatments. Ventricular fibrillation can occur immediately after chest wall injury (commotio cordis) and requires rapid defibrillation. Monomorphic ventricular tachycardia can develop in the chronic stage due to underlying structural heart disease long after blunt chest injury. The associated arrhythmogenic tissue may be complex and provides the necessary substrate to form a reentrant VT circuit. Ventricular tachycardia in the absence of overt structural heart disease appears to be focal in nature with rapid termination during ablation. Regardless of the VT mechanism, patients with recurrent episodes, despite antiarrhythmic medication in the chronic stage following blunt chest injury, are likely to require ablation to achieve VT control. This review article will describe the mechanisms, pathophysiology, and treatment of ventricular arrhythmias that occur in both the acute and chronic stages following blunt chest trauma.

    Introduction Traumatic diaphragmatic rupture (TDR) occurs in 0–5% of patients with major blunt thoraco-abdominal trauma, in most of them on the left side, and an early correct diagnosis is made in less than half of the cases (Meyers and McCabe, 1993; Ball et al., 1982). Presentation of the case We report a case of a forty-eight years old man who had a pericardio-diaphragmatic rupture after a high-velocity blunt abdominal trauma that was diagnosed and treated successfully. Discussion Pericardio-diaphragmatic rupture (PDR) is an uncommon problem that poses a diagnostic challenge to surgeons. The incidence of PDR is between 0.2% and 3.3% of cases with TDR (Sharma, 1999 [3]). Conclusion PDR should be suspected in any patient with high velocity thoraco-abdominal trauma. Early diagnosis is essential and needs a high index of suspicion. Early Management is important in decreasing morbidity and mortality. PMID:26773877

    We have studied specific morphological properties of duodenal rupture depending on the topographic and anatomical features of this organ and circumstances of blunt abdominal trauma suffered in a car crash (with the victim found in the passenger compartment or involved in an automobile-pedestrian accident) and a railway crash (a train-pedestrian accident) or resulting from a blunt-force trauma, a fall from height, a fall on the stomach, and traumatic compression of the body. We took into consideration the anatomical peculiarities of the duodenal rupture, such as its circular, horseshoe, and loop-like shape. The study has demonstrated that the frequency of duodenal injury associated with a blunt abdominal trauma shows a stronger dependence on the topographical and anatomical peculiarities of duodenum than on the circumstances of the case. Specifically, the circular duodenum and especially its descending portion are more readily subjected to the damage than the organs of a different shape. The position of the break with respect to the duodenal axis is an important diagnostic signs allowing to clarify circumstances of the blunt injury. Transverse ruptures are typical of strong impacts associated with the short-term interaction between the damaging object and the affected part of the body whereas longitudinal ruptures more commonly occur as a result the long-term traumatic impact. Bile imbibition of paraduodenal and peripancreatic retroperitoneal adipose tissue may be used as an additional diagnostic sign of duodenal rupture. PMID:24428049

    Pneumobilia is the detection of gas within the biliary system. It usually develops after bilioenteric anastomosis, percutaneous or endoscopic biliary interventions, infections and abscesses. The treatment is surgical, especially in cases with no prior interventions to the biliary system. The development of pneumobilia is quite rare after blunt trauma. Therefore, both the diagnosis and management are challenging for surgeons. Herein, we present the diagnosis and conservative management of a patient with pneumobilia after blunt trauma.

    Post-traumatic epileptic seizure is a common complication of brain trauma including military injuries. We present clinical characteristics and correlates of post-traumatic epilepsy in 163 head-injured veterans suffering from intractable epilepsy due to blunt or penetrating head injuries sustained during the Iraq-Iran war. The medical records of 163 war veterans who were admitted by the Epilepsy Department of the Shefa Neuroscience Center between 2005 and 2009 were retrospectively reviewed. The mean follow-up period after developing epilepsy was 17.2 years. The time interval between the trauma and the first seizure was shorter and the seizure frequency was higher in epileptic patients suffering from penetrating head trauma. There was no difference in seizure type between epileptic patients traumatised by blunt or penetrating injury. Patients with seizure frequency of more than 30 per month mostly had simple partial seizure. Frontal and parietal semiologies were observed more frequently in patients with penetrating trauma, whereas patients with blunt trauma showed a higher temporal semiology. The most common brain lesion observed by CT scan was encephalomalacia followed by porencephaly and focal atrophy. There was no association between intracerebral retained fragments and different characteristic features of epilepsy. Patients with military brain injury carry a high risk of intractable post-traumatic epilepsy decades after their injury, and thus require a long-term medical follow-up. PMID:22763317

    Traumatic brain injury constitutes a significant proportion of cases requiring forensic examination, and it encompasses (1) blunt, nonmissile head injury, especially involving motor vehicle accidents, and (2) penetrating, missile injury produced by a range of high- and lower-velocity projectiles. This review examines the complex pathophysiology and biomechanics of both types of neurotrauma and assesses the macroscopic and histologic features of component lesions, which may be used to determine the cause and manner of death resulting from an intentional assault or accident. Estimation of the survival time postinjury by pathologic examination is also important where malicious head injury is suspected, in an attempt to ascertain a time at which the traumatic event might have been committed, thereby evaluating the authenticity of statements made by the alleged perpetrator.

    2015-04-01

    Thoracic aortic aneurysms (TAAs) have many possible etiologies, including congenital heart defects (eg, bicuspid aortic valves, coarctation of the aorta), inherited connective tissue disorders (eg, Marfan, Ehlers-Danlos, Loeys-Dietz syndromes), and degenerative conditions (eg, medial necrosis, atherosclerosis of the aortic wall). Symptoms of rupture include a severe tearing pain in the chest, back, or neck, sometimes associated with cardiovascular collapse. Before rupture, TAAs may exert pressure on other thoracic structures, leading to a variety of symptoms. However, most TAAs are asymptomatic and are found incidentally during imaging for other conditions. Diagnosis is confirmed with computed tomography scan or echocardiography. Asymptomatic TAAs should be monitored with imaging at specified intervals and patients referred for repair if the TAAs are enlarging rapidly (greater than 0.5 cm in diameter over 6 months for heritable etiologies; greater than 0.5 cm over 1 year for degenerative etiologies) or reach a critical aortic diameter threshold for elective surgery (5.5 cm for TAAs due to degenerative etiologies, 5.0 cm when associated with inherited syndromes). Open surgery is used most often to treat asymptomatic TAAs in the ascending aorta and aortic arch. Asymptomatic TAAs in the descending aorta often are treated medically with aggressive blood pressure control, though recent data suggest that endovascular procedures may result in better long-term survival rates.

    Acute myocardial infarction following blunt chest trauma is a well reported but rare finding. Especially in severely injured patients the optimal therapy of the myocardial infarction is not well established, since anticoagulants, platelet aggregation inhibitors or thrombolytics are frequently contraindicated under these conditions. We report a case of a 41-year-old man, who presented with an acute myocardial infarction in combination with a severe polytrauma (multiple rib fractures, hematothorax, pelvic bone fractures, multiple injuries of intestinal organs) after a motorcycle accident with a blunt chest and abdominal trauma. After surgical treatment of the injuries of the bones and the intestinal organs a coronary angiography was immediately performed. The left anterior descending and the circumflex coronary artery were occluded in the mid-portion of the vessels. Coronary recanalization by PTCA and the implantation of coronary stents were successful in both vessels. Despite of a non-optimal blood flow after recanalization and stenting in one vessel (LAD TIMI II flow after recanalization), and a non-optimal accompanying medical therapy, during and after intervention (intravenous heparin starting 8 hours after the coronary intervention and platelet inhibitors starting 4 days after the intervention) the coronary angiogram after 2 months documented both vessels patent without a reocclusion or a restenosis. The case report documents, that in traumatic myocardial infarctions the treating of both, the attending injuries and the myocardial ischemia, is feasible. Early coronary angiography and coronary interventions, with or without stent-implantation, are indicated, even in cases in which an adequate accompanying medical therapy with heparin and platelet inhibitors is contraindicated.

    Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty. In this review, we discuss the anatomical factors, etiology, pathogenesis and clinical presentation of vascular TOS patients. In addition, we use the most up to date observational evidence available to provide a contemporary approach to the diagnosis and management of venous TOS and arterial TOS patients. PMID:27568153

    Of the many clinical entities involving the neck region, one of the most intriguing is thoracic outlet syndrome (TOS). TOS is an array of disorders that involves injury to the neurovascular structures in the cervicobrachial region. A classification system based on etiology, symptoms, clinical presentation, and anatomy is supported by most physicians. The first type of TOS is vascular, involving compression of either the subclavian artery or vein. The second type is true neurogenic TOS, which involves injury to the brachial plexus. Finally, the third and most controversial type is referred to as disputed neurogenic TOS. This article aims to provide the reader some understanding of the pathophysiology, workup, and treatment of this fascinating clinical entity. PMID:21824588

    Blunt trauma to the chest resulting in coronary thrombosis and ST elevation myocardial infarction (STEMI) is a rare but well-described occurrence in adults. Angiography in such cases has generally disclosed complete epicardial coronary occlusion with thrombus, indistinguishable from the findings commonly found in spontaneous plaque rupture due to atherosclerotic disease. In all previously reported cases in which coronary interrogation with intravascular ultrasound (IVUS) was performed in association with acute revascularization, coronary artery dissection was implicated as the etiology of coronary thrombosis. We present the first case report of blunt trauma-associated coronary thrombosis without underlying atherosclerosis or coronary dissection, as documented by IVUS imaging. PMID:27006836

    Early exposure to a traumatic event may produce lasting effects throughout the lifespan. Traumatic stress during adolescence may deliver a distinct developmental insult compared with more-often studied neonatal or juvenile traumatic stress paradigms. The present study describes the lasting effects of adolescent traumatic stress upon adulthood fear conditioning. Adolescent rats were exposed to a traumatic stressor (underwater trauma, UWT), then underwent fear conditioning during adulthood. Fear extinction was tested over five conditioned suppression extinction sessions three weeks later. The efficacies of two potential extinction-enhancing compounds, endocannabinoid reuptake inhibitor AM404 (10mg/kg) and M1 muscarinic positive allosteric modulator BQCA (10mg/kg), were also assessed. Finally, post-extinction fear responses were examined using a fear cue (light) as a prepulse stimulus. Rats traumatically stressed during adolescence showed blunted conditioned suppression on day 1 of extinction training, and AM404 reversed this effect. Post-extinction startle testing showed that fear conditioning eliminates prepulse inhibition to the light cue. Startle potentiation was observed only in rats without adolescent UWT exposure. AM404 and BQCA both ameliorated this startle potentiation, while BQCA increased startle in the UWT group. These results suggest that exposure to a traumatic stressor during adolescence alters developmental outcomes related to stress response and fear extinction compared to rats without adolescent traumatic stress exposure, blunting the adulthood fear response and reducing residual post-extinction fear expression. Efficacy of pharmacological interventions may also vary as a factor of developmental traumatic stress exposure. PMID:24491436

    Introduction Penetrating thoracic trauma management represents a major problem for emergency department staff. In these cases, we reported a patient, who can be deemed very lucky, because of both the trauma mechanism and the provided first aid at scene. Presentation of case A 30-year-old man was transported to the emergency surgery outpatient clinic after being stabbed from his back. A knife entered thorax from the dorsal region paravertebrally between two scapulae. No vascular and thoracic injuries were detected in the CT. The knife was then pulled and removed, and pressure dressing was applied on the wound. He was discharged with full recovery on the second day of admission. Discussion Thoracic traumas may present as blunt or penetrating traumas. Trauma with penetrating dorsal thoracic injuries is usually in the form of stabbing, sharp penetrating object injuries, or firearm injuries. The aim of a successful trauma management is to determine whether a life-threatening condition exists. The general rules of penetrating trauma management are to avoid in-depth exploration for wound site assessment, to avoid removal of penetrating object without accurate diagnosis, and to keep in mind the possibility of intubation for airway security in every moment. Conclusion During the initial care of patients with penetrating trauma, the object should not be removed from its place. Our patient was lucky enough in that no thoracic pathology developed during the accident and he was not subjected to any secondary trauma during ambulance transport. PMID:27100954

    Ten children, aged 4 to 14 years, sustaining blunt arterial trauma from motor vehicle collisions (6), bicycle accidents (2), and falls (2) were identified over a 10-year period. The arteries injured included the common iliac (3), abdominal aorta (2), carotid (2), brachial (2), and the subclavian, renal, and femoral artery (1 each). One patient had three arterial injuries. Six patients had associated injuries including a pelvic and lumbar spine fracture, Horner's syndrome, liver laceration, skull fracture, open humerus fracture, small bowel serosal tear, and a brachial plexus injury. Definitive diagnosis was made using arteriography (6), computed tomography (CT) scan (2), and physical examination (2). The types of arterial injuries found included incomplete transection, complete transection with pseudo-aneurysm formation, traumatic arteriovenous (AV) fistulas, complete occlusion, and dissection. Repair was accomplished by hypogastric artery interposition or bypass grafting, synthetic grafting with polytetrafluoroethylene (PTFE), reverse saphenous vein grafting, or primary repair, depending on the circumstances. An AV fistula between the carotid artery and cavernous sinus was embolized. All grafts remained patent with exception of the aorto-renal bypass graft at follow-up ranging from 1 month to 3 years. The principles for repairing vascular injuries in children are slightly different than those in adults. Every effort should be made to use autogenous tissue such as the hypogastric artery or saphenous vein for repair if possible. If not, PTFE grafts can be used, although the long-term patency of these grafts in growing children is not known. PMID:15156954

    The authors present a rare case of large chorioretinal rupture caused by blunt traumatic injury of the globe. A 22-year-old woman sustained a blunt injury to her left eye. The best-corrected Snellen visual acuity was 2/20 in her left eye, and hyphema and vitreous hemorrhage were noted. The day after the injury occurred the vitreous hemorrhage had disappeared. Fundus examination revealed a crescent-shaped retinal rupture three disc diameters in size near the macula, and a choroidal rupture six disc diameters in size that was over the vascular arcade. Three days after the injury, vitrectomy with internal limiting membrane peeling was performed. Postoperative prone positioning was maintained for 4 days. Five days postoperatively, closure of the ruptured retina was confirmed. The visual acuity improved to 16/20 4 months after surgery and this was maintained over a 48-month period. In conclusion, early vitrectomy with internal limiting membrane peeling after injury was effective for a case involving severe blunt chorioretinal rupture with closed globe injury. PMID:22393282

    Introduction Esophageal rupture caused by blunt chest trauma is a very rare entity, with an incidence of 0.001%. Eighty two percent of the esophageal perforation secondary to blunt chest trauma occur above the level of the carina, with the lowest reported incidence in the intrathoracic region distal to the carina. Presentation of case We report on the case of a 48-year-old Hispanic male with intrathoracic esophageal rupture. Exploration revealed a right lateral, mid esophageal, longitudinal 1.5 cm perforation. The defect was repaired using a double-layered primary closure reinforced with an intercostal muscle flap. The patient tolerated the procedure and the recovery was complicated by a pneumonic process which was treated accordingly. No leakage was found. Discussion A five-year retrospective review (2009–2013) at our institution identified 5586 trauma cases with only one case with esophageal rupture. This represents a 0.0002% of incidence of blunt esophageal rupture. This estimate is consistent with what has been previously reported in the medical literature. Our case represents a uniquely rare presentation of traumatic esophageal rupture due to the underline mechanism of injury and its anatomical location. A high index of suspicion and early intervention are critical in assuring a favorable outcome. Conclusion Diagnosis and surgical intervention with primary repair completed in the first twenty-four hours after presentation is fundamental to achieve a good outcome after esophageal rupture.

    Background and Importance Idiopathic spinal cord herniation (ISCH) is an uncommon condition located predominantly in the thoracic spine and often associated with a remote history of a major traumatic injury. ISCH has an incompletely described presentation and unknown etiology. There is no consensus on treatment algorithm and surgical technique, and there is little data on clinical outcomes. Clinical Presentation In this case series and technical report, we describe the atypical myelopathy presentation, remote history of traumatic injury, radiographic progression, treatment, and outcomes of 5 patients treated at Washington University for symptomatic ISCH. A video showing surgical repair is presented. In contrast to classic compressive myelopathy symptomology, ISCH patients presented with an atypical myelopathy, characterized by asymmetric motor and sensory deficits and early-onset urinary incontinence. Clinical deterioration correlated with progressive spinal cord displacement and herniation observed on yearly spinal imaging in a patient imaged serially due to multiple sclerosis. Finally compared to compressive myelopathy in the thoracic spine, surgical treatment of ISH led to rapid improvement despite long duration of symptoms. Conclusion Symptomatic ISCH presents with atypical myelopathy and slow temporal progression and can be successfully managed with surgical repair. PMID:24871148

    The post-traumatic osteolysis of the distal clavicle is very infrequent and the etiology and pathology is poorly understood. It is important to consider this possibility for differential diagnosis when continued pain in the acromio-clavicular joint (AC joint) follows blunt shoulder trauma. The course of the disease may result in a 3 cm loss of length of the distal clavicle. Months and years may pass until osteolysis becomes manifest, but the earliest radiological findings are present 4 weeks after trauma. The disease is self-limiting and usually does not leave residues. We report a case of a 35-year-old man with a post-traumatic osteolysis of the distal clavicle after blunt shoulder trauma. The diagnosis was determined several months after pain persisted in his shoulder. Using this case we discuss the possible pathogenic mechanism, differential diagnosis and treatment options for the post-traumatic osteolysis of the distal clavicle. PMID:11148909

    Traumatic globe dislocation into the paranasal sinuses is rare. Only 24 cases have been reported in the English-language literature indexed in PUBMED. This form of injury frequently occurs as a result of high-energy blunt trauma mainly associated to traffic accidents. Traumatic globe dislocation into the paranasal sinuses can be explained by the mechanism of blowout fracture when strong blunt trauma forces are applied to the globe fracturing the thin orbital walls and displacing the eyeball. Medical and surgical management of severe globe displacement is still controversial. However, the majority of researchers agreed that the globe should be replaced into the orbital cavity as soon as possible. The present study aims to describe a case of traumatic globe dislocation into the maxillary sinus suggesting treatment guidelines based on English-language literature from 1971 to 2015.

    Professional rugby players are prone to traumatic thoracic injuries due to the use of minimal protective gear to cover the torso. In the 2007 Rugby World Cup, thoracic injuries occurred at a rate of 8.3 cases/1000 player-hours. CT and MRI play an important role in the diagnosis of these injuries. Vital internal organs, such as the heart, lungs, trachea, liver and large blood vessels lie within close proximity to the bony structures and what seems to be a simple rib fracture or clavicular dislocation can have potentially life-threatening complications that are not detected by conventional radiography. Cross-sectional imaging helps to determine the choice of treatment. Ultrasound offers a quick and dynamic imaging examination and allows high-resolution assessment of superficial tissues that complements conventional imaging. In this review article, we (1) presented data on incidence of thoracic injuries in professional rugby players; (2) described the anatomy of the joints comprising the thoracic cage and major muscles attached to the rib cage; (3) discussed indications and relevance for MRI and presented an optimised MRI protocol for assessment of suspected thoracic injury; and (4) illustrated various types of thoracic injuries seen in professional rugby players, including sternal contusion, retrosternal haematoma, manubriosternal disruption, sternoclavicular dislocation, rib fractures and injuries of the pectoralis major muscle.

  13. Imaging of acute thoracic injury: the advent of MDCT screening.

    2005-10-01

    Chest radiography remains the primary screening study for the assessment of victims of chest trauma, but computed tomography (CT), particularly multidetector CT (MDCT), has progressively changed the imaging approach to these patients. MDCT acquires thinner sections with greater speed, allowing higher quality axial images and nonaxial reformations than conventional or single-detector helical CT. The speed of MDCT, both in acquiring data and in reconstructing images, makes the performance of total body surveys in the blunt polytrauma patient practicable. In general, CT has been well documented to offer major advantages over chest radiography in both screening for thoracic injuries and in characterizing such injuries. This capacity has been enhanced by the application of multichannel data acquisition. The greater sensitivity of MDCT has been well demonstrated in diagnosing vascular and diaphragmatic injuries. This article reviews current concepts of diagnostic imaging in acute chest trauma from blunt force and penetrating mechanisms emphasizing the spectrum of diagnostic imaging findings for various injuries, based primarily on radiographic and CT appearances. The advantages of MDCT for selected injuries are emphasized. PMID:16274001

    Blunt traumatic injuries of the intracranial carotid arteries can result in pseudoaneurysm formation. A pseudoaneurysm of the intracavernous carotid artery may rupture into the cavernous sinus, causing life-threatening epistaxis. We report a case of intracavernous traumatic psedoaneurysm presenting with delayed massive epistaxis. The endovascular treatment with overlapping self-expanding stents achieved complete exclusion of the pseudoaneurysm with preservation of the intracavernous carotid artery. PMID:19350203

    Traumatic internal carotid artery dissection secondary to blunt trauma is a rare event accounting for 0.08 to 0.4% of all traumatic lesions. The spectrum of traumatic lesions that can affect the internal carotid artery includes minor lesions like spasm, intimal tears, or mural contusions and serious lesions like pseudoaneurysms and complete occlusion. Delayed clinical presentation is typical and can include headache, hemiparesis, partial Horner's syndrome, and cranial nerve palsy. Embolization secondary to the dissection can have devastating effects because it may cause ischemic stroke. Traumatic internal carotid artery dissection after safety belt trauma is very rare; it is usually due to direct cervical trauma on the side of the shoulder fixation point, which causes external bruising along the pathway of the safety belt. We present two cases of traumatic internal carotid artery dissection with concomitant cerebral infarcts caused by safety belts; we discuss the clinical, diagnostic, and therapeutic aspects of this lesion.

    There is a direct relation between hospital costs and hospital length of stay after the operation. In the other hand, reduced stay increases the productivity of the public hospitals with high service demanding. The objective of this study was to identify factors determining the decrease in hospital stay after major thoracic surgery. A two-phase retrospective study was conducted on analysis of medical records. In the first phase, data on length of hospital stay and related factors were collected from a consecutive series of 169 patients divided into group I (n=81)--patients operated on between June 1990 and 1995, and group II (n=88)--1996 through May 2000. In the second phase, data were collected from a consecutive series of 20 patients (group III) starting backwards from March 2002, for analysis and comparison with a internet survey sent to 21 thoracic surgeons. Intensive care unit was avoided for most patients in the immediate post operative period. The mean hospital stay decreased from 7.6 days (median 7) in group I to 5.1 days (median 4) in group II (p<0.001). The more frequent utilization of epidural analgesia and less traumatic thoracotomy in group II reached statistic significance (p<0.001). In group III, the mean hospital stay was 4.2 days (median 4), and there was a more effective use of epidural analgesia (75%) and muscle-sparing thoracotomy (90%). Eight thoracic surgeons answered the survey: the mean hospital stay varied from 5 to 9 days and all patients were sent to intensive care or similar units. Only two surgeons utilize muscle-sparing thoracotomy. This study confirms that pain control and less traumatic surgical approach are important for faster functional recovery of the patients. It suggests that the IC units may be used only for selected patients. PMID:14685631

  17. A Traumatic Abdominal Wall Hernia Repair: A Laparoscopic Approach

    Wilson, Kenneth L.; Rosser, James C.

    2012-01-01

    Background: Traumatic abdominal wall hernias from blunt trauma usually occur as a consequence of motor vehicle collisions where the force is tangential, sudden, and severe. Although rare, these hernias can go undetected due to preservation of the skin overlying the hernia defect. Open repairs can be challenging and unsuccessful due to avulsion of muscle directly from the iliac crest, with or without bone loss. A laparoscopic approach to traumatic abdominal wall hernia can aid in the delineation of the hernia and allow for a safe and effective repair. Case Description: A 36-year-old female was admitted to our Level 1 trauma center with a traumatic abdominal wall hernia located in the right flank near the iliac crest after being involved in a high-impact motor vehicle collision. Computed tomography and magnetic resonance imaging of the abdomen revealed the presence of an abdominal wall defect that was unapparent on physical examination. The traumatic abdominal wall hernia in the right flank was successfully repaired laparoscopically. One-year follow-up has shown no sign of recurrence. Discussion: A traumatic abdominal wall hernia rarely presents following blunt trauma, but should be suspected following a high-impact motor vehicle collision. Frequently, repair is complicated by the need to have fixation of mesh to bony landmarks (eg, iliac crest). In spite of this challenge, the laparoscopic approach with tension-free mesh repair of a traumatic abdominal wall hernia can be accomplished successfully using an approach similar to that taken for laparoscopic inguinal hernia repair.

    OBJECTIVE: To determine the benefit of screening for blunt carotid arterial injuries (BCI) in patients who are asymptomatic. SUMMARY BACKGROUND DATA: Blunt carotid arterial injuries have the potential for devastating complications. Published studies report 23% to 28% mortality rates, with 48% to 58% of survivors having permanent severe neurologic deficits. Most patients have neurologic deficits when the injury is diagnosed. The authors hypothesized that screening patients who are asymptomatic and instituting early therapy would improve neurologic outcome. METHODS: The Trauma Registry of the author's Level I Trauma Center identified patients with BCI from 1990 through 1997. Beginning in August 1996, the authors implemented a screening for BCI. Arteriography was used for diagnosis. Patients without specific contraindications were anticoagulated. Endovascular stents were deployed in the setting of pseudoaneurysms. RESULTS: Thirty-seven patients with BCI were identified among 15,331 blunt-trauma victims (0.24%). During the screening period, 25 patients were diagnosed with BCI among 2902 admissions (0.86%); 13 (52%) were asymptomatic. Overall, eight patients died, and seven of the survivors had permanent severe neurologic deficits. Excluding those dying of massive brain injury and patients admitted with coma and brain injury, mortality associated with BCI was 15%, with severe neurologic morbidity in 16% of survivors. The patients who were asymptomatic at diagnosis had a better neurologic outcome than those who were symptomatic. Symptomatic patients who were anticoagulated showed a trend toward greater neurologic improvement at the time of discharge than those who were not anticoagulated. CONCLUSIONS: Screening allows the identification of asymptomatic BCI and thereby facilitates early systemic anticoagulation, which is associated with improved neurologic outcome. The role of endovascular stents in the treatment of blunt traumatic pseudoaneurysms remains to be defined

    Background The initial nonoperative management (NOM) of blunt splenic injuries in hemodynamically stable patients is common. In soldiers who experience blunt splenic injuries with concomitant severe brain injury while on deployment, however, NOM may put the injured soldier at risk for secondary brain injury from prolonged hypotension. Methods We conducted a decision analysis using a Markov process to evaluate 2 strategies for managing hemodynamically stable patients with blunt splenic injuries and severe brain injury — immediate splenectomy and NOM — in the setting of a field hospital with surgical capability but no angiography capabilities. We considered the base case of a 40-year-old man with a life expectancy of 78 years who experienced blunt trauma resulting in a severe traumatic brain injury and an isolated splenic injury with an estimated failure rate of NOM of 19.6%. The primary outcome measured was life expectancy. We assumed that failure of NOM would occur in the setting of a prolonged casualty evacuation, where surgical capability was not present. Results Immediate splenectomy was the slightly more effective strategy, resulting in a very modest increase in overall survival compared with NOM. Immediate splenectomy yielded a survival benefit of only 0.4 years over NOM. Conclusion In terms of overall survival, we would not recommend splenectomy unless the estimated failure rate of NOM exceeded 20%, which corresponds to an American Association for the Surgery of Trauma grade III splenic injury. For military patients for whom angiography may not be available at the field hospital and who require prolonged evacuation, immediate splenectomy should be considered for grade III–V injuries in the presence of severe brain injury.

    Introduction: In cases of blunt abdominal traumas, predicting the possible intra-abdominal injuries is still a challenge for the physicians involved with these patients. Therefore, this study was designed, to evaluate the accuracy of urinalysis in predicting intra-abdominal injuries. Methods: Patients aged 15 to 65 years with blunt abdominal trauma who were admitted to emergency departments were enrolled. Abdominopelvic computed tomography (CT) scan with intravenous contrast and urinalysis were requested for all the included patients. Demographic data, trauma mechanism, the results of urinalysis, and the results of abdominopelvic CT scan were gathered. Finally, the correlation between the results of abdominopelvic CT scan, and urinalysis was determined. Urinalysis was considered positive in case of at least one positive value in gross appearance, blood in dipstick, or red blood cell count. Results: 325 patients with blunt abdominal trauma were admitted to the emergency departments (83% male with the mean age of 32.63±17.48 years). Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of urinalysis, were 77.9% (95% CI: 69.6-84.4), 58.5% (95% CI: 51.2-65.5), 56% (95% CI: 48.5-63.3), 79.6% (95% CI: 71.8-85.7), 1.27% (95% CI: 1.30-1.57), and 0.25% (95% CI: 0.18-0.36), respectively. Conclusion: The diagnostic value of urinalysis in prediction of blunt traumatic intra-abdominal injuries is low and it seems that it should be considered as an adjuvant diagnostic tool, in conjunction with other sources such as clinical findings and imaging.

    The aim of the present study was to evaluate acute blunt pancreatic injury using contrast-enhanced ultrasonography (CEUS) in comparison with contrast-enhanced computed tomography (CECT). Superficial and deep lesions were established by blunt pancreatic injury in 40 Chinese Guangxi Bama miniature pigs. Conventional ultrasound (US), CEUS and CECT were performed to detect traumatic lesions in the pancreas. A total of 40 lesions were established, including 20 deep lesions and 20 superficial lesions. US identified 21 of the 40 lesions, including 7 of the 20 superficial and 14 of the 20 deep lesions. CEUS identified 34 of the 40 lesions, including 14 of the 20 superficial and 20 of the 20 deep lesions. CECT identified 33 of the 40 lesions, including 13 of the 20 superficial and 20 of the 20 deep lesions. The detection rate of acute blunt pancreatic injury using CEUS was significantly higher compared with that using US (85 vs. 52.5%, P<0.05), however there was no significant difference in the detection rate of pancreatic lesions between CEUS and CECT (85 vs. 82.5%, P>0.05). CEUS improves the diagnostic levels of conventional US and is comparable with CECT scans in the diagnosis of blunt pancreatic injury. PMID:23737899

    Purpose. The anterior high thoracic spine is one of the most complex segments to be accessed surgically due to anatomical constraints and transitional characteristics. We describe in detail the mini transsternal approach to metastatic, infective, traumatic, and degenerative pathologies of T1 to T4 vertebral bodies. We analyse our surgical series, indications, and outcomes. Methods. Over a 5-year period 18 consecutive patients with thoracic myelopathy due to metastatic, infective, traumatic, and degenerative pathologies with T1 to T4 vertebral bodies involvement received a mini transsternal approach with intraoperative monitoring. Frankel scoring system was used to grade the neurological status. Results. Mean follow-up was 40 months. 78% patients improved in Frankel grade after surgery and 22% patients remained unchanged. Average operation time was 210 minutes. There were no intraoperative complications. One patient developed postoperative pneumonia successfully treated with antibiotics. Conclusion. The mini transsternal is a safe approach for infective, metastatic, traumatic, and degenerative lesions affecting the anterior high thoracic spine and the only one allowing an early and direct visualisation of the anterior theca. This approach overcomes the anatomical constraints of this region and provides adequate room for optimal reconstruction and preservation of spinal alignment in the cervicothoracic transition zone with good functional patient outcomes.

    Objective To prospectively examine outcomes associated with an aggressive screening protocol for blunt cerebrovascular injury (BCVI), and to compare the accuracy of computed tomographic angiography (CTA) and magnetic resonance angiography (MRA) versus conventional angiography with respect to BCVI diagnosis. Summary Background Data In the past 5 years, BCVI (carotid and vertebral arteries) has been recognized with increasing frequency. Initial studies described blunt carotid injuries and their associated morbidity, while more recent reports have established the devastating potential of blunt vertebral injuries. It has been suggested that early diagnosis and anticoagulation will improve outcomes and that less-invasive diagnostic techniques than conventional angiography are desirable for screening. However, there are neither established screening criteria nor studies comparing optimal diagnostic modalities. Methods The screened population included all patients with cervical spine fractures, LeFort II or III facial fractures, Horner’s syndrome, skull base fractures involving the foramen lacerum, neck soft tissue injury, or neurological abnormalities unexplained by intracranial injuries. Patients underwent screening with four-vessel cerebral angiography. During the first half of the study, patients also underwent helical CTA. Selected patients during this same period underwent MRA. At the time of diagnosis, anticoagulant or antiplatelet therapy was instituted unless clinically contraindicated. Results of this screening protocol were compared to a previously published cohort with cerebrovascular injuries (1995–1999) from the authors’ institution. Results Two hundred sixteen patients were screened over a 2-year period (3.5% of all blunt trauma admissions). Angiography identified 24 patients with carotid artery injuries (CAI) and 43 patients with vertebral artery injuries (VAI) for an overall screening yield of 29%. While the incidence of CAI remained similar between

    There have been several forensic pathological studies on the distinction between falls from height and homicidal blows in blunt head trauma, but few studies have focused on suicidal blows. Self-inflicted blunt head trauma is usually a part of a complex suicide with more than one suicidal method applied. Actually, no reports on suicide indicate blunt head trauma to be the singular cause of death in recent publications. Cases with self-inflicted blunt trauma are often challenging for those involved in the investigation because they are confronted with findings that are also found in homicides. A refined guideline to differentiate suicidal blows from homicidal blows in blunt head trauma allows for a more accurate representation of the events surrounding death. This paper presents two cases of suicide by self-inflicted blunt head trauma in which blunt head trauma from repeatedly hitting the decedent's head with a hammer was considered to be the only cause of death.

    Background/Objective: An assessment of neurological improvement after surgical intervention in the setting of traumatic thoracic spinal cord injury (SCI). Methods: A retrospective evaluation of a nonconsecutive cohort of patients with a thoracic SCI from T2 to T11. The analysis included a total of 12 eligible patients. The neurologic and functional outcomes were recorded from the acute hospital admission to the most recent follow-up. Data included patient age, level of injury, neurologic examination according to the Frankel grading system, the performance of surgery, and the mechanism of the time-related SCI decompression. Results: All patients had a complete thoracic SCI. The median interval from injury to surgery was 11 days (range, 1–36 days). Decompression, bone fusion, and instrumentation were the most common surgical procedures performed. The median length of follow-up was 18 months after surgery (range, 9–132 months). Motor functional improvement was seen in 1 patient (Frankel A to C). Conclusion: Surgical decompression and fusion imparts no apparent benefit in terms of neurologic improvement (spinal cord) in the setting of a complete traumatic thoracic SCI. To better define the role of surgical decompression and stabilization in the setting of a complete SCI, randomized, controlled, prospective studies are necessary. PMID:16869088

    The development of advanced injury prediction models requires biomechanical and injury tolerance information for all regions of the body. While numerous studies have investigated injury mechanics of the thorax under frontal impact, there remains a dearth of information on the injury mechanics of the torso under blunt impact to the back. A series of hub-impact tests were performed to the back surface of the mid-thorax of four mid-size male cadavers. Repeated tests were performed to characterize the biomechanical and injury response of the thorax under various impact speeds (1.5m/s, 3m/s and 5.5m/s). Deformation of the chest was recorded with a 59-gage chestband. Subject kinematics were also recorded with a high-speed optoelectronic 3D motion capture system. In the highest-severity tests, peak impact forces ranged from 6.9 to 10.5 kN. The peak change in extension angle measured between the 1st thoracic vertebra and the lumbar spine ranged from 39 to 62°. The most commonly observed injuries were strains of the costovertebral/costotransverse joint complexes, rib fractures, and strains of the interspinous and supraspinous ligaments. The majority of the rib fractures occurred in the rib neck between the costovertebral and costotransverse joints. The prevalence of rib-neck fractures suggests a novel, indirect loading mechanism resulting from bending moments generated in the rib necks caused by motion of the spine. In addition to the injury information, the biomechanical responses quantified here will facilitate the future development and validation of human body models for predicting injury risk during impact to the back.

    Currently available diagnostic techniques for myocardial contusion following blunt chest trauma were evaluated. We investigated 30 patients prospectively over a period of 1 year for the presence of myocardial contusion. Among the 30 patients, eight were found to have myocardial contusion on the basis of abnormal electrocardiograms, elevated creatine phosphokinase MB fraction (CPK-MB), and positive myocardial scan. Myocardial scan was positive in seven of eight patients (87.5%). CPK-MB fraction was elevated in four of eight patients (50%). Definitive electrocardiographic changes were seen in only two of eight patients (25%). It appears that myocardial scan using technetium pyrophosphate and CPK-MB fraction determinations are the most reliable aids in diagnosis of myocardial contusion following blunt chest trauma.

  10. Thoracic Radiculopathy due to Rare Causes

    PubMed Central

    2016-01-01

    Thoracic radiculopathy represents an uncommon spinal disorder that is frequently overlooked in the evaluation of thoracic, or abdominal pain syndrome. The clinical representation of this uncommon disorder is often atypical. With many differential diagnoses to consider, it is not surprising that the cause of thoracic radiculopathy is often not discovered for months, or years, after the symptoms arise. We report two rare cases of thoracic radiculopathy; one case was caused by extraskeletal Ewing sarcoma (EES) along the thoracic paraspinal area, and the other by foraminal stenosis, due to a bony spur of the thoracic vertebra. As such, thoracic radiculopathy should be considered in the diagnosis of patients with thoracic and abdominal pain, especially if initial diagnostic studies are inconclusive. PMID:27446792

    It was analyzed own experience of diagnosis and treatment of catamenial (menstrual) pneumothorax and thoracic endometriosis and literature review. It is shown that catamenial pneumothorax has specific clinical and instrumental signs allowing to establish the diagnosis before surgery. It was proposed surgical treatment including the removal of trans diaphragmatic way of pneumothorax development, removal of thoracic endometriosis and the establishment of reliable pleurodesis. It was demonstrated that this volume of surgery can be successfully implemented by using of thoracoscopic access. Relapse prevention includes hormonal therapy for the 6 months after surgery under the supervision of an obstetrician-gynecologist. PMID:25484144

    The sonic-wedge characteristics method has been used to obtain the shock shapes and surface pressure distributions on several blunt two-dimensional shapes in a hypersonic stream for several values of the ratio of specific heats. These shapes include the blunt slab at angle of attack and power profiles of the form yb = a)P, where 0 les than m less than 1, Yb and x are coordinates of the body surface, and a is a constant. These numerical results have been compared with the results of blast-wave theory, and methods of predicting the pressure distributions and shock shapes are proposed in each case. The effects of a free-stream conical-flow gradient on the pressure distribution on a blunt slab in hypersonic flow were investigated by the sonic-wedge characteristics method and were found to be sizable in many cases. Procedures which are satisfactory for reducing pressure data obtained in conical flows with small gradients are presented.

  13. Delayed Presentation of Traumatic Right-Sided Diaphragmatic Hernia after Abdominoplasty

    2014-01-01

    Traumatic diaphragmatic hernias are rare and challenging to diagnose. Following trauma, diagnosis may occur immediately or in a delayed fashion. It is believed that left traumatic diaphragmatic hernias are more common as a result of the protective right-sided anatomic lie of the liver. If unrecognized, traumatic diaphragmatic injuries are subject to enlarge over time as a result of the normal pressure changes observed between the thoracic and abdominal cavities. Additionally, abrupt changes to the pressure gradients, such as those which occur with positive pressure ventilation or surgical manipulation of the abdominal wall, can act as a nidus for making an asymptomatic hernia symptomatic. We report our experience with a delayed traumatic right-sided diaphragmatic hernia presenting with large bowel incarceration two months after abdominoplasty. In our review of the literature, we were unable to find any reports of delayed presentation of a traumatic right-sided diaphragmatic hernia occurring acutely following abdominoplasty. PMID:24900935

    1990-01-01

    A numerical study was conducted to investigate the effects of blunt leading edges on the viscous flow field around a hypersonic vehicle such as the proposed National Aero-Space Plane. Attention is focused on two specific regions of the flow field. In the first region, effects of nose bluntness on the forebody flow field are investigated. The second region of the flow considered is around the leading edges of the scramjet inlet. In this region, the interaction of the forebody shock with the shock produced by the blunt leading edges of the inlet compression surfaces is analyzed. Analysis of these flow regions is required to accurately predict the overall flow field as well as to get necessary information on localized zones of high pressure and intense heating. The results for the forebody flow field are discussed first, followed by the results for the shock interaction in the inlet leading edge region.

    This study is unique in that it strives to unfold, perhaps for the first time, the problem of female mortality due to trauma in the Transkei region of the Eastern Cape Province of South Africa. This study was carried out in the Umtata and Ngqeleni magisterial districts which have a combined population of about 400,000. Most of the people have very few resources and have historically relied on money repatriated by migrant workers. The objective was to establish the incidence and the causes of deaths due to gender-related trauma and to formulate recommendations which could probably help prevent or reduce these deaths. The study reviewed cases of female traumatic death during the period January 1993 to December 1999 that were brought to the mortuary in Umtata General Hospital (UGH). There were 1,054 (23%) traumatic deaths recorded in females between 1993 and 1999. Of these 486 (28%) were related to motor vehicle collisions, 219 (18%) due to gunshot injuries, 152 (19%) due to stab wounds and 139 (21%) as a result of blunt trauma. The male to female ratio was 3.3:1 in traumatic deaths. In homicides the male:female ratio was 4.4:1, gunshot 4.5:1, stab 4.2:1 and blunt injuries 3.7:1. In motor vehicle collisions (MVC's) the ratio was 2.5:1. There is an increasing incidence of traumatic deaths in women. Gun shot injuries are the commonest among traumatic deaths in females. This article recommends stricter measures to protect women in the form of legislation. Social uplifting and economic support should be carried out as part of the process of social change. In this case educating the entire community is necessary to safeguard women and their future survival. PMID:12899426

    Confirming clinical evidence, we recently demonstrated that a blunt chest trauma considerably impaired fracture healing in rats, possibly via the interaction of posttraumatic systemic inflammation with local healing processes, the underlying mechanisms being unknown. An important trigger of systemic inflammation is the complement system, with the potent anaphylatoxin C5a. Therefore, we investigated whether the impairment of fracture healing by a severe trauma resulted from systemically activated complement. Rats received a blunt chest trauma and a femur osteotomy stabilized with an external fixator. To inhibit the C5a-dependent posttraumatic systemic inflammation, half of the rats received a C5aR-antagonist intravenously immediately and 12 h after the thoracic trauma. Compared to the controls (control peptide), the treatment with the C5aR-antagonist led to a significantly increased flexural rigidity (three-point-bending test), an improved bony bridging of the fracture gap, and a slightly larger and qualitatively improved callus (µCT, histomorphometry) after 35 days. In conclusion, immunomodulation by a C5aR-antagonist could abolish the deleterious effects of a thoracic trauma on fracture healing, possibly by influencing the function of inflammatory and bone cells locally at the fracture site. C5a could possibly represent a target to prevent delayed bone healing in patients with severe trauma. PMID:21922535

    Abdominal trauma accounts for nearly 20% of all severe traffic injuries and can often result from intentional physical violence, from which blunt liver injury is regarded as the most common result and is associated with a high mortality rate. Liver injury may be caused by a direct impact with a certain velocity and energy on the abdomen, which may result in a lacerated liver by penetration of fractured ribs. However, liver ruptures without rib cage fractures were found in autopsies in a series of cases. All the victims sustained punches on the abdomen by fist. Many studies have been dedicated to determining the mechanism underlying hepatic injury following abdominal trauma, but most have been empirical. The actual process and biomechanism of liver injury induced by blunt impact on the abdomen, especially with intact ribs remained, are still inexhaustive. In order to investigate this, finite element methods and numerical simulation technology were used. A finite element human torso model was developed from high resolution CT data. The model consists of geometrically-detailed liver and rib cage models and simplified models of soft tissues, thoracic and abdominal organs. Then, the torso model was used in simulations in which the right hypochondrium was punched by a fist from the frontal, lateral, and rear directions, and in each direction with several impact velocities. Overall, the results showed that liver rupture was primarily caused by a direct strike of the ribs induced by blunt impact to the abdomen. Among three impact directions, a lateral impact was most likely to cause liver injury with a minimum punch speed of 5 m/s (the momentum was about 2.447 kg.m/s). Liver injuries could occur in isolation and were not accompanied by rib fractures due to different material characteristics and injury tolerance. PMID:23308111

    Degenerative aneurysms of the thoracic aorta are increasing in prevalence; open repair of descending thoracic aortic aneurysms is associated with high rates of morbidity and mortality. Repair of isolated descending thoracic aortic aneurysms using stent grafts was introduced in 1995, and in an anatomically suitable subgroup of patients with thoracic aortic aneurysm, repair with endovascular stent graft provides favorable outcomes, with decreased perioperative morbidity and mortality relative to open repair. The cornerstones of successful thoracic endovascular aneurysm repair are appropriate patient selection, thorough preprocedural planning, and cautious procedural execution, the elements of which are discussed here.

    Paintball is a popular recreational sport played at both amateur and professional level. Ocular injuries are well recognised, although there is a growing body of literature documenting superficial vascular as well as deep solid organ injuries. An 18-year-old man presented with signs and symptoms consistent with acute appendicitis. Intraoperatively, a grade III liver injury was identified and packed before a relook at 48 h. No further active bleeding was identified; however, follow-up ultrasound at 3 weeks demonstrated non-resolution of a large subcapsular haematoma. The patient was readmitted for a short period of observation and discharged with repeat ultrasound scheduled for 3 months. This represents the first report of paintball-related blunt traumatic injury to the liver. Solid organ injuries of this nature have only been reported three times previously-all in the urological setting. This case also highlights issues surrounding the use of routine follow-up imaging in blunt liver trauma and provides a concise discussion of the relevant literature. PMID:27122206

    Objective To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. Materials and Methods A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Results Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Conclusion Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair. PMID:27587969

    Previous studies have examined the effects of heating on teeth; however, none have identified characteristics that allow analysts to differentiate traumatic from heat-induced fractures. This study examined our ability to discern notable differences in preincineration traumatic fractures and heat-induced fractures in postincineration dentition. Twelve anterior dental specimens were subjected to blunt force trauma while a second set were not. All 24 samples were then incinerated in a muffle furnace at a peak temperature (900°C) consistent with house fires. The specimens were subsequently examined with a scanning electron microscope to identify and compare heat-induced and traumatic fractures. The results obtained during examination yielded no differences between the features displayed by specimens that had been inflicted with preincineration trauma and those that did not. Unlike bone, distinguishing features for the differentiation of traumatic and heat-induced fractures could not be compiled. PMID:21521217

    Segmental renal infarction is a rare situation which has been reported so far in the form of case reports. It's caused usually by cardiac conditions, such as atrial fibrillation, and systemic diseases (e.g. systemic lupus erythematous). We are presenting a case of a 31 year old healthy male, who sustained a left segmental renal infarction, following a motorbike accident. We report his presentation, management and outcome. We also review the literature in search of the optimal diagnostic and treatment pathway. To our knowledge, this is the first report of segmental renal infarction due to blunt trauma. PMID:27175338

    Segways and other personal transporters are emerging as alternative modes of transportation that blur the distinction between pedestrian and vehicular traffic. We reviewed the records of four patients who were traumatically injured while piloting personal transporters. All required hospital admission for major blunt force trauma; three were admitted to the intensive care unit. Two intensive care unit admissions were for neurologic monitoring of severe intracranial hemorrhage. The other critically ill patient had an extensive chest wall injury and respiratory failure resulting in a tracheostomy. The fourth patient suffered an open lower extremity fracture requiring extensive reconstructive orthopedic surgery. Surgeons should be aware of the potential serious nature of associated injuries.

    Pelvic trauma can lead to severe, uncontrollable haemorrhage and death related to prolonged shock and multiple organ failure. Massive retroperitoneal haematoma should be assumed to be present in cases of post-traumatic haemodynamic instability associated with pelvic fracture in the absence of extrapelvic haemorrhagic lesions. This review describes the pathophysiology of retroperitoneal haematoma in trauma patient with blunt pelvic fracture, considering the roles of venous and arterial bleeding. Efficacy and safety of haemostatic procedures are also discussed, and particular attention is given to the efficacy of pelvic angiographic embolization and external pelvic fixation. A decision making algorithm is proposed for the treatment of trauma patients with pelvic fracture that takes haemodynamic status and associated lesions into account. PMID:17300738

    The clinical history and operative findings in a group of 60 patients who underwent reoperation for thoracic outlet syndrome (TOS) are presented. The patients were severely disabled by arm, shoulder, and neck pain and presented with physical findings pointing to scar fixation of the brachial plexus in the neck (upper tract recurrence) or at the thoracic outlet (lower tract recurrence). The causes of recurrence of TOS as discovered at operation are outlined. Basic principles governing the surgical management of recurrent TOS are elimination of the known causes of recurrence, thorough neurolysis of the brachial plexus, and coverage of the nerves with healthy fat. The role of an expanded PTFE surgical membrane (Gortex) as an adjunct to prevent recurrent scarring is discussed. The surgeon who operates on patients with recurrent TOS must be capable of managing the potential intraoperative complications of severe nerve injury and life threatening bleeding. PMID:2745532

    Acute pancreatitis (AP) is relatively uncommon in pediatric age group. Traumatic injury is an important cause of AP in children. Ductal disruption resulting from pancreatic trauma usually needs surgical intervention. A three-and-a-half year old child presented with complaints of abdominal pain and distension following blunt trauma abdomen. Computed tomography of abdomen revealed presence of grade III pancreatic injury with fluid collection in lesser sac. The patient was managed with antibiotics and pigtail drainage and he improved.

    Introduction Computed tomography is commonly used to exclude occult injuries in patients with trauma, but imaging can reveal findings that are of uncertain etiology or clinical significance. We present a case of unsuspected pancreatic abnormality in a female patient with trauma who sustained an isolated blunt head injury. Case presentation A 25-year-old female Caucasian patient sustained massive blunt and penetrating head trauma, secondary to a large object penetrating through the vehicle windshield. Based on the mechanism of injury and clinical evaluation, it was felt to be an isolated head injury. However, computed tomography of her abdomen revealed an occult, intra-abdominal finding of significant pancreatic enlargement and peripancreatic fluid. There was no computed tomography evidence of parenchymal pancreatic laceration. The appearance of her pancreas on computed tomography was identical to that of acute pancreatitis or low-grade pancreatic injury, but her clinical history and laboratory values were not consistent with this, hence the term ‘pseudopancreatitis’. Later surgery for organ donation confirmed diffuse pancreatic and peripancreatic edema, but no hematoma, contusion or other evidence for direct traumatic injury. This was an isolated intra-abdominal abnormality. Conclusion The routine use of computed tomography in patients who have sustained trauma has led to increasing detection of unexpected findings. Clinical information such as mechanism of injury and blood work, along with careful evaluation of ancillary imaging findings (or lack of), is important for the provision of an appropriate differential diagnosis. We discuss the possible mechanism and differential diagnosis of an isolated pancreatic abnormality in the setting of non-abdominal trauma, which includes shock pancreas, overhydration, traumatic pancreatic injury and pancreatitis secondary to other etiologies.

    Abstract Several clinical, imaging, and therapeutic factors affecting recovery following spinal cord injury (SCI) have been described. A systematic review of the topic is still lacking. Our primary aim was to systematically review clinical factors that may predict neurological and functional recovery following blunt traumatic SCI in adults. Such work would help guide clinical care and direct future research. Both Medline and Embase (to April 2008) were searched using index terms for various forms of SCI, paraplegia, or quadri/tetraplegia, and functional and neurological recovery. The search was limited to published articles that were in English and included human subjects. Article selection included class I and II evidence, blunt traumatic SCI, injury level above L1-2, baseline assessment within 72 h of injury, use of American Spinal Injury Association (ASIA) scoring system for clinical assessment, and functional and neurological outcome. A total of 1526 and 1912 citations were located from Medline and Embase, respectively. Two surgeons reviewed the titles, abstracts, and full text articles for each database. Ten articles were identified, only one of which was level 1 evidence. Age and gender were identified as two patient-related predictors. While motor and functional recovery decreased with advancing age for complete SCI, there was no correlation considering incomplete ones. Therefore, treatment should not be restructured based on age in incomplete SCI. Among injury-related predictors, severity of SCI was the most significant. Complete injuries correlated with increased mortality and worse neurological and functional outcomes. Other predictors included SCI level, energy transmitted by the injury, and baseline electrophysiological testing. PMID:19831845

    Pediatric neurosurgeons frequently care for children with traumatic scalp and skull injury. Foreign objects are often observed on imaging and may influence the clinician's decision-making process. The authors report on 2 cases of poorly visualized hair beads that had become embedded into the skull during blunt trauma. In both cases, skull radiography and CT scanning demonstrated depressed, comminuted fractures with poorly demonstrated spherical radiolucencies in the overlying scalp. The nature of these objects was initially unclear, and they could have represented air that entered the scalp during trauma. In one case, scalp inspection demonstrated no evidence of the bead. In the other case, a second bead was observed at the site of scalp laceration. In both cases, the beads were surgically removed, the fractures were elevated, and the patients recovered uneventfully. Radiolucent fashion accessories, such as hair beads, may be difficult to appreciate on clinical examination and may masquerade as clinically insignificant air following cranial trauma. If they are not removed, these foreign bodies may pose the risk of an infection. Pediatric neurosurgeons should consider hair accessories in the differential diagnosis of foreign bodies that may produce skull fracture following blunt trauma. PMID:19035690

    A case of horseshoe-shaped macular tear after blunt trauma with the course of the tear and the relevant findings obtained by spectral-domain optical coherence tomography (SD-OCT) is described. A 21-year-old man who had suffered blunt trauma 5 days previously visited our clinic complaining of vision loss in his left eye. Ophthalmic examination and SD-OCT images revealed a horseshoe-shaped macular tear. A month later at the second visit, the macular tear was found to have spontaneously closed. There have been many cases reported previously of the spontaneous closure of traumatic macular holes. A horseshoe-shaped macular tear is an atypical clinical presentation. However, the mechanism of spontaneous closure is hypothetically as same as that for a macular hole. High-resolution images and three-dimensional maps taken with SD-OCT can provide more details on macular diseases and are more useful than time-domain OCT images. PMID:24817754

    H. Julian Allen is best known for his 'Blunt Body Theory' of aerodynamics, a design technique for alleviating the severe re-entry heating problem which was then delaying the development of ballistic missiles. His findings revolutionized the fundamental design of ballistic missle re-entry shapes. Subsequently, applied research led to applications of the 'blunt' shape to ballistic missles and spacecraft which were intended to re-enter the Earth's atmosphere. This application led to the design of ablative heat shields that protected the Mercury, Gemini and Apollo astronauts as their space capsules re- entered the Earth's atmosphere. 'Harvey' Allen as he was called by most, was not only a brilliant scientist and aeronautical engineer but was also admired for his kindness, thoughtfulness and sense of humor. Among his many other accomplishments, Harvey Allen served as Center Director of the NASA Ames Research Center from 1965 to 1969. He died of a heart attack on January 29, 1977 at the age of 66.

    We report 2 cases of surgical treatment of blunt cardiac trauma. The postoperative course was uneventful in either case. Pericardial drainage in patients with cardiac rupture should be performed with preparation for thoracotomy. Case 1: A 34-year-old male, hit in the chest by a collapsing 700-kg steel rod, was transported to our hospital via ambulance. The patient was diagnosed as having a cardiac rupture by echocardiography and underwent emergency thoracotomy. The right atrium near the inferior vena cava (IVC) was damaged, though bleeding from the wound had already ceased. No suture hemostusis was needed. Case 2: A 63-year-old female was hit by a car and transported to our hospital due to blunt trauma to the chest. Low blood pressure and chest computed tomography demonstrated cardiac tamponade, and subxiphoid pericardial drainage was performed. Blood pressure was recovered, but persistent hemorrhage necessitated emergency thoracotomy, which revealed a laceration at the right atrium near IVC. The injury was sutured to achieve complete hemostasis. PMID:18323181

    The morbidity, mortality, and economic costs resulting from trauma in general, and blunt abdominal trauma in particular, are substantial. The "panscan" (computed tomographic [CT] examination of the head, neck, chest, abdomen, and pelvis) has become an essential element in the early evaluation and decision-making algorithm for hemodynamically stable patients who sustained abdominal trauma. CT has virtually replaced diagnostic peritoneal lavage for the detection of important injuries. Over the past decade, substantial hardware and software developments in CT technology, especially the introduction and refinement of multidetector scanners, have expanded the versatility of CT for examination of the polytrauma patient in multiple facets: higher spatial resolution, faster image acquisition and reconstruction, and improved patient safety (optimization of radiation delivery methods). In this article, the authors review the elements of multidetector CT technique that are currently relevant for evaluating blunt abdominal trauma and describe the most important CT signs of trauma in the various organs. Because conservative nonsurgical therapy is preferred for all but the most severe injuries affecting the solid viscera, the authors emphasize the CT findings that are indications for direct therapeutic intervention.

    Pancreatic injuries are relatively uncommon but present a major challenge to the surgeon in terms of both diagnosis and management. Pancreatic injuries are associated with significant mortality, primarily due to associated injuries, and pancreas-specific morbidity, especially in cases of delayed diagnosis. Early diagnosis of pancreatic trauma is a key for optimal management, but remains a challenge even with more advanced imaging modalities. For both penetrating and blunt pancreatic injuries, the presence of main pancreatic ductal injury is the major determinant of morbidity and the major factor guiding management decisions. For main pancreatic ductal injury, surgery remains the preferred approach with distal pancreatectomy for most injuries and more conservative surgical management for proximal ductal injuries involving the head of the pancreas. More recently, nonoperative management has been utilized, especially in the pediatric population, with the potential for increased rates of pseudocyst and pancreatic fistulae and the potential for the need for further intervention and increased hospital stay. This review presents recent data focusing on the diagnosis, management, and outcomes of blunt pancreatic injury. PMID:26038029

    Nanotechnology is an emerging, rapidly evolving field with the potential to significantly impact care across the full spectrum of cancer therapy. Of note, several recent nanotechnological advances show particular promise to improve outcomes for thoracic surgical patients. A variety of nanotechnologies are described that offer possible solutions to existing challenges encountered in the detection, diagnosis and treatment of lung cancer. Nanotechnology-based imaging platforms have the ability to improve the surgical care of patients with thoracic malignancies through technological advances in intraoperative tumour localization, lymph node mapping and accuracy of tumour resection. Moreover, nanotechnology is poised to revolutionize adjuvant lung cancer therapy. Common chemotherapeutic drugs, such as paclitaxel, docetaxel and doxorubicin, are being formulated using various nanotechnologies to improve drug delivery, whereas nanoparticle (NP)-based imaging technologies can monitor the tumour microenvironment and facilitate molecularly targeted lung cancer therapy. Although early nanotechnology-based delivery systems show promise, the next frontier in lung cancer therapy is the development of 'theranostic' multifunctional NPs capable of integrating diagnosis, drug monitoring, tumour targeting and controlled drug release into various unifying platforms. This article provides an overview of key existing and emerging nanotechnology platforms that may find clinical application in thoracic surgery in the near future. PMID:26843431

    Although potato cannons are an area of great interest among internet users, they are almost completely unknown in the medical community. These simple ballistic devices are made from plastic plumbing pipes and are powered with propellant gas from aerosol cans. By combustion of the gas-oxygen mixture, a high pressure is produced which propels the potato chunks through the barrel. It is the aim of this study to investigate the hazardous potential of these shooting devices. Test shots were performed using three illegally manufactured potato cannons that were confiscated by police authorities. Velocity, impulse, kinetic energy, and energy density were calculated. The risk of head and chest injuries was investigated by using Sturdivan's Blunt Criterion (BC), an energy based five parametric trauma model assessing the vulnerability to blunt weapons, projectile impacts, and behind-body-armor exposures. The probability of lethality due to blunt impact trauma to the chest was assessed using Sturdivan's lethality model. For potential head impacts, all test shots far exceeded the critical BC (head) value which corresponds to a 50% risk of skull fracture. The risk of injury with regard to chest impacts was similar. All but two test shots far exceeded the critical BC (chest) value corresponding to a 50% risk of sustaining a thoracic skeletal injury of Abbreviated Injury Scale 2 or 3. The probability of a lethal injury due to blunt chest impact was as high as 20%. To conclude, this work demonstrates that potato cannons should be considered dangerous weapons rather than as toys used by adventurous adolescents. PMID:21279374

    Traumatic pseudoaneurysm involving the maxillary artery is rare. Owing to its anatomic location, internal maxillary artery is usually protected by its surrounding structures. Formation of pseudoaneurysm usually takes place after several weeks to months of the initial injury. In this case, we reported a pseudoaneurysm arising from left internal maxillary artery following blunt injuries within 3 hours after a road accident and the treatment with endovascular embolization with titanium coils prior to open reduction and internal fixation of the fractured mandibles.

  3. Experimental traumatic brain injury

    PubMed Central

    2010-01-01

    Traumatic brain injury, a leading cause of death and disability, is a result of an outside force causing mechanical disruption of brain tissue and delayed pathogenic events which collectively exacerbate the injury. These pathogenic injury processes are poorly understood and accordingly no effective neuroprotective treatment is available so far. Experimental models are essential for further clarification of the highly complex pathology of traumatic brain injury towards the development of novel treatments. Among the rodent models of traumatic brain injury the most commonly used are the weight-drop, the fluid percussion, and the cortical contusion injury models. As the entire spectrum of events that might occur in traumatic brain injury cannot be covered by one single rodent model, the design and choice of a specific model represents a major challenge for neuroscientists. This review summarizes and evaluates the strengths and weaknesses of the currently available rodent models for traumatic brain injury. PMID:20707892

    2015-01-01

    Although sports-related injuries to the thoracic spine are relatively uncommon, they are among the most feared due to the potential for catastrophic neurologic injury. The increased biomechanical support of the thoracic spine makes injuries in this region particularly rare compared with the cervical and lumbar spine. As a result, thoracic spine injuries can be missed easily, difficult to diagnose, and problematic to treat. Recognition of mechanism and awareness of injury patterns help physicians determine a diagnosis and create an index of suspicion for unstable thoracic spine injuries. Aggressive full-contact sports receive the most attention for spinal injury; however several sports with repetitive loading of the spine can cause severe injuries, including rowing, gymnastics, and golf. The goal of this article was to provide an overview of the unique anatomic and biomechanical features of the thoracic spine and to discuss some of the more common thoracic injuries that can affect athletes.

    Introduction Blunt abdominal trauma is a rare but well-recognized cause of pancreatic transection. A delayed presentation of pancreatic fracture following sport-related blunt trauma with the coexisting diagnostic pitfalls is presented. Case Report A 17-year-old rugby player was referred to our specialist unit after having been diagnosed with traumatic pancreatic transection, having presented 24 h after a sporting injury. Despite haemodynamic stability, at laparotomy he was found to have a diffuse mesenteric hematoma involving the large and small bowel mesentery, extending down to the sigmoid colon from the splenic flexure, and a large retroperitoneal hematoma arising from the pancreas. The pancreas was completely severed with the superior border of the distal segment remaining attached to the splenic vein that was intact. A distal pancreatectomy with spleen preservation and evacuation of the retroperitoneal hematoma was performed. Discussion/Conclusion Blunt pancreatic trauma is a serious condition. Diagnosis and treatment may often be delayed, which in turn may drastically increase morbidity and mortality. Diagnostic difficulties apply to both paraclinical and radiological diagnostic methods. A high index of suspicion should be maintained in such cases, with a multi-modality diagnostic approach and prompt surgical intervention as required. PMID:21490833

    The development of thoracic endovascular aortic repair (TEVAR) has allowed a minimally invasive approach for management of an array of thoracic aortic pathologies. Initially developed specifically for exclusion of thoracic aortic aneurysms, TEVAR is now used as an alternative to open surgery for a variety of disease pathologies due to the lower morbidity of this approach. Advances in endograft technology continue to broaden the applications of this technique. PMID:26327745

    The aim of this study is to develop a reliable and efficient design tool that can be used in hypersonic flows. The flow analysis is based on the axisymmetric Euler/Navier-Stokes and finite-rate chemical reaction equations. The equations are coupled simultaneously and solved implicitly using Newton's method. The Jacobian matrix is evaluated analytically. A gradient-based numerical optimization is used. The adjoint method is utilized for sensitivity calculations. The objective of the design is to generate a hypersonic blunt geometry that produces the minimum drag with low aerodynamic heating. Bezier curves are used for geometry parameterization. The performances of the design optimization method are demonstrated for different hypersonic flow conditions.

    Tracheobronchial avulsion resulting from blunt trauma is a very rare and serious condition, mostly due to high-speed traffic crashes. In this article, we briefly report the case of an 18-year-old man who was injured in a car accident and because of massive persistent air leakage (despite appropriate chest tube drainage), deemed to have a deep tracheobronchial injury. Due to a rapid drop in the patient's O2 saturation, he underwent an anterolateral thoracotomy. Endotracheal intubation was performed under direct visualization. The right mainstem bronchus was disrupted from the carina with a 1.5-cm stump remaining on the carina, and the remainder was crushed to the origin of the right superior lobe bronchus. Hence, a right superior lobectomy was performed and the postoperative course was uneventful. PMID:26157657

    With the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. However, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. Injuries may consist of traumatic abdominal wall disruption. We present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair. A review of the literature is provided. Two patients were brought in after a high velocity Motor Vehicle Collision. Both presented with an acute abdomen and a seatbelt sign upon which the decision was made to perform emergency laparotomies. Both patients had an abdominal wall disruption along the seatbelt sign. These disruptions were primarily closed and during six months of follow-up no complications occurred. A disruption of the abdominal wall is a rare complication. However, it is a diagnosis that may not be missed as patients have a higher risk of morbidity and mortality. CT-scanning is an accurate method to detect disruptions. Closure of blunt traumatic abdominal wall disruption can be done primarily with sutures or addition of a mesh. In both cases of the severe abdominal wall disruption, primary repair without mesh in the acute phase was successful. When a laparotomy is not indicated, the abdominal wall must be assessed for disruption. If there is a disruption primary repair is a good option. PMID:27331068

    Summary We present a very rare example of chronic right heart failure caused by torrent tricuspid regurgitation. Massive right heart dilatation and severe tricuspid regurgitation due to avulsion of the tricuspid valve apparatus occurred as a result of a blunt chest trauma following the explosion of a gas bottle 20 years before admission, when the patient was a young man in Vietnam. After this incident, the patient went through a phase of severe illness, which can retrospectively be identified as an acute right heart decompensation with malaise, ankle edema, and dyspnea. Blunt chest trauma caused by explosives leading to valvular dysfunction has not been reported in the literature so far. It is remarkable that the patient not only survived this trauma, but had been managing his chronic heart failure well without medication for over 20 years. Learning points Thorough clinical and physical examination remains the key to identifying patients with relevant valvulopathies.With good acoustic windows, TTE is superior to TEE in visualizing the right heart.Traumatic avulsion of valve apparatus is a rare but potentially life-threatening complication of blunt chest trauma and must be actively sought for. Transthoracic echocardiography remains the method of choice in these patients. PMID:27249554

    Impalement injuries are rare and among the most spectacular and dramatic traumatic lesions. The survival of a patient with a thoracic impalement injury is an extremely rare event. The objective of this study was to present the case of a 24-year-old male patient with a severe thoracic impalement injury successfully treated despite his late arrival in our hospital. A log in 12 cm diameter penetrated his right thorax producing injuries of the right main bronchus, right pulmonary lobe, right subclavian artery as well as extensive parietal lesions. Definitive surgical repair of these lesions was performed more than seven hours after trauma. The management principles contributing to the successful outcome that we would like to emphasize are: rapid transportation and reaction of the trauma team, minimal manipulation of the impaling object, removal of the log as one piece under direct vision in the operating room, ventilatory support, extensive debridement, and lavage associated with appropriate antibiotherapy.

    BACKGROUND: Canada’s contributions toward the 21st century’s practice of thoracic surgery have been both unique and multilayered. Scattered throughout are tales of pioneers where none had gone before, where opportunities were greeted by creativity and where iconic figures followed one another. OBJECTIVE: To describe the numerous and important achievements of Canadian thoracic surgeons in the areas of surgery for pulmonary tuberculosis, thoracic oncology, airway surgery and lung transplantation. METHOD: Information was collected through reading of the numerous publications written by Canadian thoracic surgeons over the past 100 years, interviews with interested people from all thoracic surgery divisions across Canada and review of pertinent material form the archives of several Canadian hospitals and universities. RESULTS: Many of the developments occurred by chance. It was the early and specific focus on thoracic surgery, to the exclusion of cardiac and general surgery, that distinguishes the Canadian experience, a model that is now emerging everywhere. From lung transplantation in chimera twin calves to ex vivo organ preservation, from the removal of airways to tissue regeneration, and from intensive care research to complex science, Canadians have excelled in their commitment to research. Over the years, the influence of Canadian thoracic surgery on international practice has been significant. CONCLUSIONS: Canada spearheaded the development of thoracic surgery over the past 100 years to a greater degree than any other country. From research to education, from national infrastructures to the regionalization of local practices, it happened in Canada.

  17. The Thoracic Shape of Hominoids

    In hominoids, the broad thorax has been assumed to contribute to their dorsal scapular position. However, the dorsoventral diameter of their cranial thorax was found in one study to be longer in hominoids. There are insufficient data on thoracic shape to explain the relationship between broad thorax and dorsal scapular position. The current study presents data on multilevel cross-sectional shape and volume distribution in a range of primates. Biplanar radiographs of intact fluid-preserved cadavers were taken to measure the cross-sectional shape of ten equally spaced levels through the sternum (called decisternal levels) and the relative volume of the nine intervening thoracic segments. It was found that the cranial thorax of hominoids is larger and broader (except in the first two decisternal levels) than that of other primates. The cranial thorax of hominoids has a longer dorsoventral diameter because the increase in dorsoventral diameter caused by the increase in the volume of the cranial thorax overcompensates for the decrease caused by the broadening of the cranial thorax. The larger and broader cranial thorax in hominoids can be explained as a locomotor adaptation for scapular gliding and as a respiratory adaptation for reducing the effects of orthograde posture on ventilation-perfusion inequality.

    Although great progress has been achieved in thoracic organ transplantation through the development of effective immunosuppression, there is still significant risk of rejection during the early post-transplant period, creating a need for routine monitoring for both acute antibody and cellular mediated rejection. The currently available multiplexed, microbead assays utilizing solubilized HLA antigens afford the capability of sensitive detection and identification of HLA and non-HLA specific antibodies. These assays are being used to assess the relative strength of donor specific antibodies; to permit performance of virtual crossmatches which can reduce the waiting time to transplantation; to monitor antibody levels during desensitization; and for heart transplants to monitor antibodies post-transplant. For cell mediated immune responses, the recent development of gene expression profiling has allowed noninvasive monitoring of heart transplant recipients yielding predictive values for acute cellular rejection. T cell immune monitoring in heart and lung transplant recipients has allowed individual tailoring of immunosuppression, particularly to minimize risk of infection. While the current antibody and cellular laboratory techniques have enhanced the ability to manage thoracic organ transplant recipients, future developments from improved understanding of microchimerism and graft tolerance may allow more refined allograft monitoring techniques.

  20. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    Idiopathic spinal cord herniation (ISCH) is a rare spinal disease, in which chronic cerebrospinal fluid pulsations push the arachnoid and adjacent thoracic spinal cord region through an antero-lateral dural defect of congenital, post-traumatic, or inflammatory/erosive origin. Symptomatic patients commonly present around the 5th decade of life with slowly progressive myelopathy. Diagnosis relies on high-resolution magnetic resonance imaging. Stable mild cases may be observed, whereas in progressive symptomatic situations, surgical spinal cord reposition and dural defect repair with a dural patch is the preferred treatment. We present a case of ISCH at T5/6 and a review the literature. PMID:27221089

Methods Six patients with a syndrome of nerve trapping without specific nerve strain limitations were followed up. Results The patients achieved improvement of their symptoms 6–20 months after the procedure. The motor symptoms completely disappeared, without any persistent pain. The medial deformity of the winged scapula improved in all cases, without any residual esthetic disorders. Conclusion The approach of early surgical release seems to be a better predictor for recovery from non-traumatic paralysis of the anterior serratus muscle. PMID:26535205

    2010-01-01

    Mild traumatic brain injury (mTBI) refers to the clinical condition of transient alteration of consciousness as a result of traumatic injury to the brain. The priority of emergency care is to identify and facilitate the treatment of rare but potentially life threatening intra-cranial injuries associated with mTBI through the judicious application of appropriate imaging studies and neurosurgical consultation. Although post-mTBI symptoms quickly and completely resolve in the vast majority of cases, a significant number of patients will complain of lasting problems that may cause significant disability. Simple and early interventions such as patient education and appropriate referral can reduce the likelihood of chronic symptoms. Although definitive evidence is lacking, mTBI is likely to be related to significant long-term sequelae such as Alzheimer's disease and other neurodegenerative processes. PMID:20709244

    2015-01-01

    Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended. PMID:26698210
