    Hemobilia is defined as the presence of blood in the biliary tree characterized by the triad: jaundice, right hypochondrium pain (RH) and upper gastrointestinal bleeding (UGB). Among the etiologies highlighted in order of frequency there are: liver trauma (accidental and iatrogenic), inflammatory causes (acute and chronic cholecystitis), infections (cholangitis, liver abscesses, parasitic infections) and vascular diseases (aneurysms, vasculitis, arteriovenous malformations). There exist many complementary tests for the diagnosis of hemobilia, such as imaging (abdominal ultrasound, CT scan, angio CT), videoendoscopy, endoscopic retrograde cholangiopancreatography and angiography, the latter being considered the diagnostic tool and therapeutic modality of choice. We report the case of a 52-year-old male patient with hemobilia secondary to apseudoaneurysm ofthe hepatic artery, along with a review of the existing literature.

    Pseudoaneurysm of a cystic artery is a rare entity that commonly occurs secondary to biliary procedures. Most of the cases in literature are consisted of ruptured aneurysms and to our knowledge, except our case, there were only 3 cases with unruptured aneurysms, which incidentally were detected by radiological methods. When cystic artery pseudoaneurysm is present with acute cholecystitis, most of the reports in literature suggested open cholecystectomy with the ligation of the cystic artery as a main treatment option. In this paper we present a case of acute cholecystitis with unruptured cystic artery pseudoaneurysm that incidentally was detected by computed tomography (CT). Cystic artery pseudoaneurysm was handled laparoscopically with simultaneous cholecystectomy. Due to high risk of rupture, surgeons have evaded laparoscopic approach to acute cholecystitis, which accompanied cystic artery pseudoaneurysm. However herein, we proved that laparoscopic management of cystic artery pseudoaneurysm with simultaneous cholecystectomy is feasible and reliable method. PMID:27635274

    Gastric tuberculosis (TB) is very rare compared with other sites in the gastrointestinal (GI) tract, and upper GI bleeding is an extremely rare manifestation of gastric TB. Also, a pseudoaneurysm is an uncommon cause of GI bleeding and is often encountered with pancreatitis. To our knowledge, no case of GI bleeding due to a pseudoaneurysm of the splenic artery secondary to gastric TB has been reported previously. We report a patient who presented with hematemesis due to a pseudoaneurysm of the splenic artery secondary to gastric TB.

    Arterial pseudoaneurysm of the lower limb is an infrequent entity, particularly in the infrapopliteal segment. It is commonly associated to vascular repairs or follows a localized arterial lesion, a fracture or a surgical procedure. There is little information in Mexico about this entity in cases involving the anterior tibial artery, and secondary to trauma and osteosynthesis. Given that sudden bleeding due to rupture of the pseudoaneurysm is a possible catastrophic outcome for the viability of the segment, it is important to timely detect and diagnose the pseudoaneurysm. Treatment indications contained in the international literature are controversial. Solution-oriented approaches may be either surgical or endovascular. Current reports show that the best treatment option is an autologous saphenous vein graft, which maintains blood flow and minimizes the risk of peripheral ischemia. The purpose of this paper is to report the case of a patient who sustained the above mentioned complication and provide a literature review. This topic should be further investigated, as this condition may go unnoticed in a large number of cases, given that its symptoms are silent. PMID:27627775

    A bleeding pseudoaneurysm of the peripancreatic artery can present with massive upper gastrointestinal hemorrhage. History of pancreatitis and urgent imaging are crucial in the making of the diagnosis. Here, we report a patient with alcoholic chronic pancreatitis presented with ruptured pseudoaneurysm of gastroduodenal artery (GDA). He was treated with percutaneous angiographic embolisation.

    We report a case of an uncommon giant pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis. It presented with a perfused volume of 17.3 cm3 close to the branch-off of the right hepatic artery. Superselective transcatheter embolization including interlocking detachable coils and a mixture of Ethibloc and Lipiodol was our technique of choice. Following the procedure, the patient was in hemodynamically stable condition. At that time, he was free of any clinical symptoms and showed no further signs of bleeding or ischaemia. Additionally, we present an overview of the relevant literature. PMID:22690281

    We report the case of a patient who developed an asymptomatic pseudoaneurysm in the left external iliac artery after transplant nephrectomy. The pseudoaneurysm most probably arose as a suture aneurysm from the external iliac artery after removal of the graft renal artery. Obviously we can not exclude the possibility it was a true aneurysm, although this seems much less likely. The pseudoaneurysm was detected during a routine CT scan and was treated interventionally with a stent-graft. One month later the asymptomatic patient underwent a vascular ultrasound examination including color Doppler, power Doppler, and B-flow as a routine control. An endoleak with collapse of the stent-graft was diagnosed. There was no evidence of stent infection. At a reintervention, the pseudoaneurysm was successfully treated using two uncovered Palmaz stents at the proximal and distal edge of the stent graft. Peri- and post-interventional ultrasound and CT angiography confirmed the exclusion of the aneurysm without an endoleak.

    Isolated injury to the brachiocephalic artery is relatively rare. We report the case of a 53-year-old lymphoma patient who had had a biopsy at mediastinoscopy in the past and was found incidentally on routine staging computed tomography to have developed a large pseudoaneurysm of the brachiocephalic artery. We describe the successful percutaneous treatment of this iatrogenic injury using endovascular deployment of covered stent-grafts.

There was no pathologic finding at selective facial and internal maxillary artery injections. An injury to the ethmoidal branches of the ophthalmic arteries or other arterial origins of bleeding was suspected. The internal carotid artery angiography revealed a pseudoaneurysm of an anterior ethmoidal branch of the left ophthalmic artery. The pseudoaneurysm was occluded with NBCA-histoacryl (25%) injection.

    Although n-butyl-2-cyanoacrylate (NBCA) has been used as an effective liquid embolization material, its indication for pseudoaneurysms has seemingly been limited because of the technical difficulties of using NBCA, such as reflux to the parent artery and causing significant infarction. Thus, considerable skill in using NBCA or a device to control blood flow during its polymerization is required to achieve embolization without severe complications. We report our new technique for controlling blood flow using diluted epinephrine in transcatheter arterial NBCA embolization of five pseudoaneurysms in four cases secondary to hemosuccus pancreaticus.

    2015-01-01

    Pseudoaneurysms of the superficial temporal artery are an uncommon vascular lesion of the external carotid system and most often the result of blunt head trauma. The frequency of pseudoaneurysms of the superficial temporal artery developing after craniotomy is exceedingly low and only a few cases have been reported. We present a case of pseudoaneurysm of this type in a 45-year-old male who underwent craniotomy for excision of meningioma. One month postoperatively, the craniotomy flap exhibited an enormous diffuse pulsate swelling. The suspected diagnosis of pseudoaneurysm arising from superficial temporal artery was confirmed on angiography. Surgical excision was done and no recurrences of the tumor or aneurysm were noted on subsequent follow up. PMID:26501064

    An early diagnosis of popliteal artery pseudoaneurysm-a sequela of popliteal artery trauma-is difficult owing to its late presentation following total knee arthroplasty. The incidence of a popliteal artery pseudoaneurysm with a hematoma presenting only a peripheral nerve injury after total knee arthroplasty is also uncommon in the absence of common diagnostic features such as a pulsatile swelling with an audible bruit on auscultation. In the present report, we describe popliteal artery pseudoaneurysm following total knee arthroplasty. PMID:24944978

    Pseudoaneurysms of the superficial temporal artery are a rare and potentially critical cause of facial masses. Most pseudoaneurysms form as a result of blunt trauma and present as painless, pulsatile tumors that may be associated with neuropathic findings and enlarged size. Without careful evaluation in the primary care setting, pseudoaneurysms can be easily misdiagnosed and improperly managed. They can, however, be accurately diagnosed through physical examination alone and subsequently treated with surgical ligation. The authors present two cases of traumatic pseudoaneurysms of the superficial temporal artery caused by blunt injury and discuss pertinent diagnosis and treatment options, as well as provide a brief review of the anatomy and histopathology of pseudoaneurysms.

    Abstract Aneurysm or pseudoaneurysm formation is one of the vascular complications of Behcet disease. At present, the optimal treatment for the disease has not been established. The authors report a case of vasculo-Behcet disease (v-BD) with recurrent pseudoaneurysms in the left infrainguinal arteries (common femoral artery, superficial femoral artery, and popliteal artery), as well as thrombosis in the popliteal vein and posterior tibial vein. The patient underwent 3 rounds of surgery, but developed a new pseudoaneurysm several months after each surgery. Eventually, the patient was successfully treated with a combination of endovascular repair, using a fully covered stent graft, and prednisone. The pseudoaneurysm regressed without recurrence for more than 1 year. For v-BD, treatment with immunosuppressive therapy alone may not be sufficient to prevent the recurrence of pseudoaneurysms. For the endovascular treatment of pseudoaneurysms affecting the infrainguinal arteries in v-BD, a fully covered stent graft without oversizing is essential to prevent the recurrence of pseudoaneurysms.

    We report a case of pseudoaneurysm of the parietal division of the superficial temporal artery (STA) secondary to iatrogenic head injury due to Gardner traction. A 54-year-old man presented with a pulsatile, cystic, and painless mass in the right anterior temporal region which developed three weeks after head fixation via Gardner traction. At the time of discovery, the mass was 10 mm in diameter, compressible and disappeared after manual compression of the proximal STA. A bruit was audible over the mass, which was thought to be a pseudoaneurysm. A computed tomography angiogram (CTA) showed a pseudoaneurysm of the parietal division of the right STA. The tip of the pseudoaneurysm was thrombosed and was both red and tender. The pseudoaneurysm was thought to be filled with infected thrombus, and the mass was resected with ligation of the proximal and distal ends of the STA. A pseudoaneurysm of the STA should be suspected when there is a history of possible vessel injury, such as a history of head-pin fixation, and when a patient presents with a pulsatile, cystic mass near the temple. Pseudoaneurysms can be successfully treated by excision.

Left renal pelvis stones were found and standard percutaneous nephrolithotomy was successfully performed. Two weeks later, the patient suddenly suffered massive bleeding presented with gross hematuria. Rupture of ectopic renal artery pseudoaneurysm was identified by computed tomography and angiography of the renal artery. Emergency selective angioembolization of one branch of the artery was performed. To our knowledge, this is the first report of ruptured ectopic renal arterial pseudoaneurysm. PMID:27564300

We performed RFA for a pulmonary epithelioid hemangioendothelioma directly adjacent to a branch of the PA. Seventeen days later, the patient complained of hemoptysis. A chest CT image revealed PA pseudoaneurysm. Transcatheter coil embolization was performed 59 days after RFA. Although PA pseudoaneurysm is rare, with an incidence of 0.2% (1/538 sessions) at our institution, it should be recognized as a risk when treating lung tumors adjacent to a branch of the PA.

    Pseudoaneurysms due to chronic pancreatitis can be a source of major gastrointestinal (GI) hemorrhage. Computed tomography (CT) is the primary diagnostic imaging modality for pancreatic pseudocysts associated with GI bleeding. Pseudoaneurysms and associated GI bleeding can be diagnosed and embolized with transcatheter techniques once the arterial anatomy is defined. CT is a useful modality for follow-up examination of the pseudocyst; the findings must be correlated with other procedures performed on these patients. On follow-up studies, contrast medium retained in the pseudocyst after embolization may falsely signal persistent bleeding into the pseudocyst.

    Behçet's disease is a systemic vasculitis of unknown etiopathogenesis. Arterial events such as pseudo-aneurysms are rare and may be the mode of occurrence of the disease. These pseudo-aneurysms tend, regardless of size, to progress rapidly to life-threatening rupture. We report two cases of arterial pseudo-aneurysms that ruptured. Treatment consisted of surgical repair in one case and arterial ligation in the other; the postoperative course was uneventful in both cases.

    Carotid artery pseudoaneurysm is a rare condition, particularly in the paediatric population. Only about 30 cases of carotid artery aneurysms in infants have been published until now. This paper reports the case of a giant pseudoaneurysm of the left common carotid artery due to swallowed fish bone by an 8-year-old boy. This pseudoaneurysm was 5.5 cm transverse-diameter and resulted in severe respiratory distress. It was treated by resection and end-to-end anastomosis with satisfactory outcome after one-year follow-up. To the best of our knowledge, this is the largest carotid artery pseudoaneurysm ever described in children. PMID:26783485

    Visceral artery pseudoaneurysms occur mostly as a result of inflammation and trauma. Owing to high risk of rupture, they require early treatment to prevent lethal complications. Knowledge of the various approaches of embolization of pseudoaneurysms and different embolic materials used in the management of visceral artery pseudoaneurysms is essential for successful and safe embolization. We review and illustrate the endovascular, percutaneous and endoscopic ultrasound techniques used in the treatment of visceral artery pseudoaneurysm and briefly discuss the embolic materials and their benefits and risks.

    We report a case of nontraumatic rupture of the lumbar artery that led to a pseudoaneurysm in the vertebral body and massive retroperitoneal to retropleural hematoma. The pseudoaneurysm was successfully treated by endovascular embolization. To our knowledge, idiopathic rupture of the lumbar artery has been reported in a limited number of cases and pseudoaneurysm formation in the vertebral body has not been presented in the literature. The etiology of hemorrhage has been discussed based on CT, MRI, and three-dimensional rotational angiography.

    Abstract Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was immediately and successfully managed with endovascular embolization. There was no bleeding or complications 6 months after the embolization. PMID:27213747

    An 82-year-old woman underwent right hemicolectomy by median laparotomy. Two weeks later, a pulsatile mass was found at the left side of the surgical wound, which was diagnosed as pseudoaneurysm of the inferior epigastric artery by color Doppler US and CT. The pseudoaneurysm was successfully treated by US-guided compression of the neck of the aneurysm for 30 minutes. US-guided compression should be considered the treatment of choice for postsurgical pseudoaneurysm of the inferior epigastric artery.

    Summary Background Visceral artery aneurysms (VAAs) comprise an uncommon but life-threatening vascular disease. When rupture is the first clinical presentation, mortality rate reaches 70%. Increased use of cross-sectional imaging has led to a greater rate of diagnosis (40–80%) of asymptomatic VAAs. In the past, surgery was the treatment of choice for VAAs carrying high risk of mortality and morbidity. Case Report A 22-year-old man, who had undergone gastric, pancreatic and aortic surgery 2.5 years earlier, presented with progressive abdominal pain. Multidetector computed tomography scan revealed an 8-cm celiac pseudoaneurysm. We report a giant celiac pseudoaneurysm treated with stent-graft implantation. Conclusions Endovascular treatment of VAA is a safe and effective method alternative to surgery. PMID:26236417

Vertebral artery pseudoaneurysm complicating posterior C1-C2 transarticular fixation is extremely rare, with only one previous case having been reported previously. Endovascular occlusion is better achieved in the subacute phase of the pseudoaneurysm, when the wall of the pseudoaneurysm has matured and stabilized. Further follow-up angiographies are mandatory in order to confirm that there is no recurrence of the lesion.

    We report two cases of acutely infected pseudoaneurysms of the iliac arteries, successfully treated with endovascular stent-grafting. Two patients underwent stent-graft treatment for erosive rupture of the iliac artery caused by surrounding infection. The first case is that of a 61-year-old man who had undergone Miles' operation for an advanced rectal cancer. Postoperatively, he developed intrapelvic abscess formation, from which methicillin-resistant Staphylococcus aureus was cultured, followed by rupture of the right external iliac artery. The second case is that of a 60-year-old man who had a pseudoaneurysm of the left common iliac artery, which was contiguous with a left psoas muscle abscess, from which Streptococcus agalactiae was cultured. Both patients were successfully treated with only a stent-graft and antibiotic therapy, and remained symptom-free 12 months and 10 months later. Although endovascular stent-grafting should not be considered standard therapy for infected aneurysms, our cases suggest that it can result in repair of infected aneurysms even in the uncontrolled active stage.

    Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed. The authors present a case of a HAP in a 56-year-old female presenting with jaundice and pruritis suggestive of a Klatskin’s tumor. This presentation of HAP in a patient without any significant past medical or surgical intervention is atypical when considering that the majority of HAP cases present secondary to iatrogenic causes or trauma. Multiple minimally invasive approaches were employed in an attempt to alleviate the symptomology which included jaundice and associated inflammatory changes. Ultimately, a right hepatic trisegmentectomy was required to adequately relieve the mass effect on biliary outflow obstruction and definitively address the HAP. The presentation of a HAP masquerading as a malignancy with jaundice and pruritis, rather than the classic symptoms of abdominal pain, anemia, and melena, is unique. This presentation is only further complicated by the absent history of either trauma or instrumentation. It is important to be aware of HAPs as a potential cause of jaundice in addition to the more commonly thought of etiologies. Furthermore, given the morbidity and mortality associated with pseudoaneurysm rupture, intervention in identifiable cases, either by minimally invasive or surgical interventions, is recommended.

The pseudoaneurysm recurred after the initial successful thrombin injection. With a second injection we obtained permanent pseudoaneurysm occlusion. Our case illustrates that this procedure is an effective treatment in this type of arteriovenous fistula complication. We compare this case with the only similar one we could find in the literature.

We report an unusual case of lobulated pseudoaneurysm arising from one of the branches of the left internal iliac artery during acetabulum preparation in THA, which was successfully treated with coil embolization and multidisciplinary care. After 6 years follow up, patient did not have any symptoms related to the hip replacement. We recommend that surgeons should be extremely cautious while drilling medial wall of the acetabulum for depth assessment. Aggressive multidisciplinary approach, including possible support from an interventional radiologist is required for the treatment of such vascular injuries. PMID:27053814

    Subclavian artery pseudoaneurysm and occlusion in young patients are usually post-traumatic. We report the case of a 33-year-old diabetic woman with subclavian artery occlusion and pseudoaneurysm formation caused by pulmonary mucormycosis infection. The patient presented with diabetic ketoacidosis, Horner's syndrome, and absent left arm pulses. A cystic lesion of the left lung apex was found by imaging, was surgically resected, and was histologically diagnosed as mucormycosis infection. Magnetic resonance angiography depicted a left subclavian artery pseudoaneurysm and occlusion adjacent to the mucormycosis lesion. To protect against thromboembolic complications and rupture, the pseudoaneurysm was embolized with coils. The patient is clinically well 1 year after the intervention with no perfusion of the pseudoaneurysm.

This patient received steroid therapy for chronic rheumatoid arthritis for several years. The digital subtraction angiography of the right renal artery showed two pseudoaneurysms in the anterior inferior segmental branch and the posterior inferior segmental branch. Transarterial coil embolization of the right renal artery proximally and distally to the two aneurysms was performed without complications. Moreover, the additional angiography showed typical string-of-beads appearance and small aneurysms in abdominal visceral arteries, suggesting segmental arterial mediolysis (SAM) as a possible etiology. Differential diagnoses of SAM are discussed.

    Medical ultrasound imaging with Doppler plays an essential role in the diagnosis of vascular disease. This study intended to review the clinical use of “to-and-fro” waveform at duplex Doppler ultrasonography (DDU) in the diagnosis of pseudoaneurysms in the arterial vessels of upper and lower extremities, abdominal aorta, carotid and vertebral arteries as well as to review our personal experiences of “to-and-fro” waveform at DDU also. After receiving institutional review board approval, an inclusive literature review was carried out in order to review the scientific foundation of “to-and-fro” waveform at DDU and its clinical use in the diagnosis of pseudoaneurysms in various arterial vessels. Articles published in the English language between 2000 and 2013 were evaluated in this review study. Pseudoaneurysms in arterial vessels of the upper and lower extremities, abdominal aorta, carotid and vertebral arteries characterized by an extraluminal pattern of blood flow, which shows variable echogenicity, interval complexity, and “to-and-fro” flow pattern on color Doppler ultrasonography. In these arterial vessels, Duplex ultrasonography can demonstrate the degree of clotting, pseudoaneurysm communication, the blood flow patterns and velocities. Spectral Doppler applied to pseudoaneurysms lumen revealed systolic and diastolic turbulent blood flow with traditional “to-and-fro” waveform in the communicating channel. Accurate diagnosis of pseudoaneurysm by spectral Doppler is based on the documentation of the “to-and-fro” waveform. The size of pseudoaneurysm determines the appropriate treatment approach as surgical or conservative. PMID:26029351

    A true aneurysm is defined as an enlargement of an artery resulting in a diameter more than 1.5 times the anatomic size. It can be fusiform when it covers the entire perimeter of the vessel, or saccular when it bulges on one side of the artery. The pseudoaneurysm is a pulsating encapsulated haematoma in communication with the lumen of the ruptured vessel,which affects the the intima and the media and which is stopped from developing by the adventitia and the surrounding connective tissue. Geographically, aneurysm can be broadly divided into intracranial and extracranial types.While the neurosurgeon manages the intracranial types, the vascular surgeon manages the extracranial types. Vascular surgeons also do divide the extracranial types into central (abdominal-aorto-iliac, thoracic including ascending, transverse aortic arch and descending), peripheral (extremities) and visceral (splanchnic arteries). Splanchnic artery aneurysm includes the coeliac, superior mesenteric, inferior mesenteric arteries including their branches. Of all intra-abdominal aneurysms, only around 5% are due to the splanchnic arteries,which could be either true or pseudo. The prevalence has been estimated at 0.1-0.2%. PMID:27487600

    Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions ≥2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment. PMID:26595501

    PurposeTo assess the role and effectiveness of percutaneous arterial embolization (TAE) in patients with hemodynamic instability due to hypovolemic shock secondary to ruptured splanchnic artery pseudoaneurysms (SAPA).Materials and MethodsSeventeen patients (11 men, 6 women; mean age, 53 years) with hemodynamic instability (systolic blood pressure <90 mmHg) due to hypovolemic shock secondary to ruptured SAPA were treated by TAE. Clinical files, multidetector row computed tomography angiography, and angiographic examinations along with procedure details were reviewed.ResultsSeventeen SAPAs were present, predominantly located on gastroduodenal or pancreatic arteries (9/17; 53 %). Angiography showed extravasation of contrast medium from SAPA in 15/17 patients (88 %). Technical success rate of TAE was 100 %. TAE was performed using metallic coils in all patients (100 %), in association with gelatin sponge in 5/17 patients (29 %). TAE allowed controlling the bleeding and returning to normal hemodynamic status in 16/17 patients (94 %). In 1/17 patient (6 %), surgery was needed to definitively control the bleeding. The mortality and morbidity rate of TAE at 30 days were 0 and 12 %, respectively. Morbidity consisted in coil migration in 1/17 patient (6 %) and transient serum liver enzyme elevation in 1/17 patient (6 %).ConclusionTAE is an effective and safe treatment option for ruptured SAPA in hemodynamically unstable patients, with a success rate of 94 %. Our results suggest that TAE should be the favored option in patients with hemodynamic instability due to ruptured SAPA.

    Massive hemobilia caused by hepatic artery pseudoaneurysm is an uncommon but potentially fatal complication that can occur after biliary intervention. Previous intervention or surgery, atherosclerotic disease, inflammation and even anatomic variants may make the pseudoaneurysm inaccessible to transcatheter approach, therefore it is not always feasible. The present report describes a case of successful embolization of a hepatic artery pseudoaneurysm with N-butyl cyanoacrylate via direct puncture as an alternative approach. The case presentation is followed by the technical points and the properties of N-butyl cyanoacrylate that are particularly advantageous for use in direct puncture procedures.

    A 35-year-old patient was brought to the emergency department referring dysarthria, left ear tinnitus for 5 min, and short-lasting blindness, with headache in the 45 min before the clinical presentation. In the magnetic resonance imaging, an acute-subacute lesion in the cerebellum right-anterior lobe (in the territory of the cerebellum anterior artery) and a dilatation near the ostium of the right vertebral artery were seen. For a better assessment, an Angio-CT was done, showing a 9-mm saccular pseudoaneurysm of the right vertebral artery close to the origin of the vessel, without being able to determine if it had been caused because of a dissection. The rest of the study (cerebral vessels and supra-aortic vessels) showed no disorders. He was operated under local anesthesia and sedation a week after the onset of the symptoms. Through a 0.014 wire, a Biotronik PK Papyrus balloon-expandable covered cobalt-chromium stent was deployed covering the hole in the artery. Antiplatelet drugs were prescribed, and the patient was discharged 24 hr after surgery. He has remained symptom free since then. PMID:25770383

    INTRODUCTION Pseudoaneurysm of the cystic artery is very rare. In the majority of cases it has been reported as a post-operative complication of laparoscopic cholecystectomy, however it has also been associated with the presence of acute cholecystitis or pancreatitis. When these pseudoaneurysms rupture they can lead to intraperitoneal bleeding, haemobilia and upper gastrointestinal haemorrhage. Radiological as well as open surgical approaches have been described for control of this rare pathology. PRESENTATION OF CASE We report the laparoscopic surgical management of an incidental, unruptured cystic artery pseudoaneurysm in a patient presenting with acute cholecystitis. DISCUSSION Cystic artery pseudoaneurysm is a rare entity and as such there is no consensus on the clinical management of this condition. A variety of treatment strategies have been reported in the literature including radiological selective embolisation and coiling, open cholecystectomy with ligation of the aneurysm, or a two-step approach involving radiological management of the pseudoaneurysm followed by an elective cholecystectomy. CONCLUSION In this report we have demonstrated that laparoscopic management of a cystic artery pseudoaneurysm with simultaneous laparoscopic cholecystectomy is feasible and safe. This avoids multiple invasive procedures and decreases morbidity associated with open surgery. PMID:26291047

  8. Giant uterine artery pseudoaneurysm after a missed miscarriage termination in a cesarean scar pregnancy

    2014-01-01

    Background Uterine artery pseudoaneurysms are dangerous and can lead to severe hemorrhage. We report an uncommon cause of a giant pseudoaneurysm in a missed miscarriage in a woman with a cesarean scar pregnancy. Case presentation The patient was a 25-year-old Chinese woman with a missed miscarriage in a cesarean scar pregnancy. Curettage was performed under ultrasound monitoring. A uterine artery pseudoaneurysm measuring 71 × 44 × 39 mm was detected the next day by Doppler ultrasonography. While waiting for admittance to an advanced institution to undergo embolization treatment, the pseudoaneurysm ruptured spontaneously. The subsequent severe hemorrhage necessitated hysterectomy. Conclusion A delay in diagnosis of uterine artery pseudoaneurysms may result from a long period between the curettage and follow-up examination. Ultrasound and Doppler ultrasonography should be performed repeatedly at short intervals to rule out them, especially in cesarean scar pregnancies. For a giant uterine artery pseudoaneurysm, interventional embolization might be the first treatment choice. If time allows, intra-operative ligation of the feeding vessels should be attempted before any decision to perform a hysterectomy is made. However, hysterectomy remains a possibility when severe bleeding occurs. PMID:25070087

    We report two patients with arteriovenous hemodialysis fistulas that were complicated by brachial artery pseudoaneurysms. Each pseudoanerysm was percutaneously thrombosed with an injection of thrombin, using techniques to prevent escape of thrombin into the native brachial artery. In one patient, an angioplasty balloon was inflated across the neck of the aneurysm during thrombin injection. In the second patient, thrombin was injected during ultrasound-guided compression of the neck of the pseudoaneurysm. Complete thrombosis of each pseudoaneurysm was achieved within 30 sec. No ischemic or embolic events occurred. This technique may be useful in treating pseudoaneurysms of smaller peripheral arteries.

    Pseudoaneurysm is a relatively rare but serious complication of pancreatitis which is often fatal. We report successful stent-graft placement in the superior mesenteric artery in a 45-year-old man with a pancreatic pseudocyst that grew during therapy for chronic pancreatitis and developed into a pseudoaneurysm. After a stent graft was inserted in the superior mesenteric artery, the pseudoaneurysm disappeared and no further complications developed. Stent-graft placement was considered to be a useful therapy for pseudoaneurysms in the superior mesenteric arterial region.

Although there is a good argument for postponing surgery until transcatheter embolization has been attempted, this case shows that embolization can still be successful even if the iliac vessels have been ligated.

    Although pseudoaneurysm of the posterior tibial artery has been reported, no investigators have discussed the development of a pseudoaneurysm after manipulation under anesthesia of a total ankle replacement. We present the case of a 59-year-old female with end-stage post-traumatic tibiotalar joint disease who underwent an uneventful INBONE® Total Ankle Replacement. She experienced continued postoperative pain and impingement after physical therapy. Consequently, she underwent manipulation under anesthesia. The manipulation provided complete and immediate pain relief. However, she developed a pseudoaneurysm of the posterior tibial artery that required vascular repair. She recovered uneventfully and was ambulating free of pain with improved functionality. Although manipulation under anesthesia of a total ankle replacement is a valuable, noninvasive tool that can provide near-immediate pain relief, it is important to realize that this distal arterial injury, although uncommon, is a possibility.

    2015-01-01

    We report a 48-year-old man in whom a chronic postbulbar duodenal ulcer destroyed much of the back wall of the duodenum and gastroduodenal artery causing pseudoaneurysm. The lesion was found and evaluated by contrast-enhanced computed tomography (that revealed a large pseudoaneurysm of 83 mm × 75 mm in diameter) and by angiography and then treated with transcatheter embolization leading to a complete resolution of the lesion. The case is rare and important for several reasons. First, we demonstrate that pseudoaneurysm of the gastroduodenal artery caused by a duodenal ulcer can occur and present a diagnostic challenge (as far as we know, only three cases have been reported previously in the literature). Second, this case report focuses on the importance of ligation of the gastroduodenal artery when bleeding of peptic ulcers occurs. Additionally, we present an overview of the relevant literature.

    To describe when and how to perform endovascular embolization of aortic branch artery pseudoaneurysms associated with type A and type B intramural hematoma (IMH) involving the descending thoracic and abdominal aorta (DeBakey I and III) that increased significantly in size during follow-up. Sixty-one patients (39 men; mean {+-} standard deviation age 66.1 {+-} 11.2 years) with acute IMH undergoing at least two multidetector computed tomographic examinations during follow-up for 12 months or longer were enrolled. Overall, 48 patients (31 men, age 65.9 {+-} 11.5) had type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III). Among the 48 patients, 26 (54 %; 17 men, aged 64.3 {+-} 11.4 years) had 71 aortic branch artery pseudoaneurysms. Overall, during a mean follow-up of 22.1 {+-} 9.5 months (range 12-42 months), 31 (44 %) pseudoaneurysms disappeared; 22 (31 %) decreased in size; two (3 %) remained stable; and 16 (22 %) increased in size. Among the 16 pseudoaneurysms with increasing size, five of these (three intercostal arteries, one combined intercostobronchial/intercostal arteries, one renal artery), present in five symptomatic patients, had a significant increase in size (thickness >10 mm; width and length >20 mm). These five patients underwent endovascular embolization with coils and/or Amplatzer Vascular Plug. In all patients, complete thrombosis and exclusion of aortic pseudoaneurysm and relief of back pain were achieved. Aortic branch artery pseudoaneurysms associated with type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III) may be considered relatively benign lesions. However, a small number may grow in size or extend longitudinally with clinical symptoms during follow-up, and in these cases, endovascular embolization can be an effective and safe procedure.

    Purpose: Our purpose was to evaluate iatrogenic renal pseudoaneurysms, endovascular treatment, and outcomes. Methods: This retrospective study (2003-2011) reported the technical and clinical outcomes of endovascular therapy for renal pseudoaneurysms in eight patients (mean age, 46 (range 24-68) years). Renal parenchymal loss evaluation was based on digital subtraction angiography and computed tomography. Results: We identified eight iatrogenic renal pseudoaneurysm patients with symptoms of hematuria, pain, and hematoma after renal biopsy (n = 3), surgery (n = 3), percutaneous nephrolithotomy (n = 1), and endoscopic shock-wave lithotripsy (n = 1). In six patients, the pseudoaneurysms were small-sized (<20 mm) and peripherally located and were treated solely with coil embolization (n = 5). In one patient, coil embolization was preceded by embolization with 500-700 micron embospheres to control active bleeding. The remaining two patients had large-sized ({>=}50 mm), centrally located renal pseudoaneurysms treated with thrombin {+-} coils. Technical success with immediate bleeding cessation was achieved in all patients. There were no procedure-related deaths or complications (mean follow-up, 23.5 (range, 1-67) months). Conclusions: Treatment of renal pseudoaneurysms using endovascular approach is a relatively safe and viable option regardless of location (central or peripheral) and size of the lesions with minimal renal parenchymal sacrifice.

    A 71-year-old man affected by cardio- and cerebrovascular disease experienced an accidental fall and trauma to the fronto-temporal area of the head. A few weeks later a growing mass appeared on his scalp. A diagnosis of superficial temporal artery pseudoaneurysm was made following CT and color Doppler ultrasound. His clinical condition favoured a conservative approach by ultrasound-guided compression and subsequent surgical resection. A conservative approach should be considered the treatment of choice in critically ill patients affected by superficial temporal artery pseudoaneurysm.

    Summary Background Spinal artery ischemia is a rare but serious complication of embolization for treatment of hemoptysis. When the spinal artery is visualized at angiography, embolization should not be performed. However, it has been reported that spinal artery feeders are not visible on angiography in patients with developing spinal infarction. Case Report A 70-year-old man with a history of pulmonary aspergillosis had hemoptysis and underwent contrast-enhanced CT, revealing a pulmonary artery pseudoaneurysm (PAP) in the left upper lobe. Systemic angiography from the fifth left intercostal artery showed the PAP at the distal site, but the access route to the PAP was very tortuous and long. Although the spinal branch could not be observed with that angiography, CT during angiography was performed, and it visualized the posterior spinal artery obviously. Thus, the artery distal and proximal to the PAP was then successfully coil-embolized from the pulmonary artery. Conclusions CT during angiography may be useful to confirm the presence of the spinal artery for treatment of hemoptysis by embolization.

    Femoral artery pseudoaneurysms (FAPs) have been described following internal fixation of intertrocantheric, subtrocantheric and intracapsular femoral neck fractures as well as core decompression of the femoral head. The diagnosis of FAP is usually delayed because of non-specific clinical features like pain, haematoma, swelling, occasional fever and unexplained anaemia. Because of the insidious onset and of the possible delayed presentation of pseudoaneurysms, orthopaedic and trauma surgeons should be aware of this complication. We report a case of Profunda Femoris arterial branch pseudoaneurysm, diagnosed in a 40-year-old male 4 wk after revision with Kuntscher intramedullary nail of a femoral shaft nonunion. The diagnosis was achieved by computed tomography angiography and the lesion was effectively managed by endovascular repair. The specific literature and suggestions for treatment are discussed in the paper. PMID:23878785

    Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

    The purpose is to describe a case of traumatic right extracranial internal carotid artery (EICA) pseudoaneurysm, which is a rare entity and the evolution of treatment from surgery to minimally invasive intervention by endovascular stenting and coiling. We reported a case of traumatic right EICA pseudoaneurysm who presented with multiple cranial nerve palsies. Multiple radiological examinations [including magnetic resonance imaging (MRI) with angiogram, computed tomography angiogram (CTA), and digital subtraction angiogram (DSA)] demonstrated right EICA pseudoaneurysm. The pseudoaneurysm was successfully treated with endovascular stenting and coiling. EICA pseudoaneurysm is a rare entity, and open surgery was the gold standard of treatment. Current technology allows endovascular stenting and coiling of pseudoaneurysm as an alternative treatment. It is minimally invasive, associated with lesser complications, better recovery and a shorter hospital stay. PMID:27547119

    Background: Recurrence of a cervical internal carotid artery (ICA) pseudoaneurysm initially treated by endovascular means is rare. We report an instance where a patient returned with a recurrent, enlarging cervical ICA pseudoaneursym, 15 years after initial complete, endovascular occlusion of the ICA. Case Description: Patient is a 64-year-old male with a history of a right cervical ICA pseudoaneurysm diagnosed 15 years ago after a car accident. At the time, he received endovascular occlusion of his right ICA. Recent serial imaging demonstrated progressive enlargement of his pseudoaneurysm, up to 6 cm × 5 cm × 5.5 cm, without evidence of internal flow or extravasation. Due to dysphagia and hoarseness, resection of the pseudoaneurysm was recommended. Dissection occurred down to the lesion, where its borders were skeletonized. Its stump at the proximal ICA was mobilized and clamped; the lesion was incised and the existing thrombus, as well as the coil mass, was removed. The distal ICA appeared completely scarred with no retrograde filling. There were branches from the external carotid artery that appeared to supply the pseudoaneurysm. The scarred remnant of the distal ICA was sutured and the stump at the proximal ICA was ligated. Once hemostasis was obtained, closure occurred via anatomical layers. Postoperatively, the patient woke up well; at discharge, he exhibited no respiratory distress or dysphagia. At 5 months follow-up, a computed tomography angiography of the neck revealed no evidence for a residual pseudoaneurysm. He continues on lifelong aspirin. Conclusion: Recurrence of a cervical ICA pseudoaneursym is rare. We caution that such a clinical scenario is possible, even 15 years after endovascular occlusion of the ICA. Branches from the external carotid artery may feed the pseudoaneursym and cause recurrence. This mechanism has not been reported. Perhaps longer clinical follow-up is necessary, especially if endovascular therapy is the initial treatment

    Mycotic pseudoaneurysm of the pulmonary artery that ruptures during necrotizing pneumonia is a rare entity that is often fatal. Traditionally it has been treated with open thoracotomy and resection of both the aneurysm and the lobe in which the aneurysm is located. In this report, we describe the radiological findings and transcatheter coil embolization of a mycotic pulmonary pseudoaneurysm in a 6-month-old female infant. We also describe the subsequent morphologic changes observed on follow-up computed tomography after 9 months of embolization.

    Iatrogenic intracranial pseudoaneurysm formation and rupture are rare complications following endoscopic sinus surgery. Given the propensity for devastating neurologic injury after a relatively routine procedure, swift diagnosis and treatment is essential. The authors present a patient who experienced bifrontal intracranial hemorrhage and subarachnoid hemorrhage due to a ruptured iatrogenic frontopolar artery pseudoaneurysm caused during routine endoscopic sinus surgery. The pseudoaneurysm was not present on initial angiograms but became apparent radiographically 19 days after the endoscopic procedure. Endovascular treatment consisted of coil and Onyx embolization for sacrifice of the parent vessel proximal to the lesion. Early recognition of iatrogenic intracranial vascular injury is important to allow for rapid treatment. Initial radiographic studies may be unreliable in excluding the presence of a pseudoaneurysm so delayed repeat angiographic assessment is necessary, particularly in the presence of a high index of clinical suspicion. Endovascular techniques may provide an effective and safe option for the treatment of iatrogenic anterior cerebral artery distribution pseudoaneurysms.

    Although aneurysmal complications of sickle cell anemia have been described in the intracranial circulation, visceral artery pseudoaneurysms in this disease entity have not previously been reported in the literature. Conventional treatment of visceral pseudoaneurysms has been surgical ligation or resection of the aneurysm. Transcatheter embolization has emerged as an attractive, minimally invasive alternative to surgery in the treatment of these lesions. In certain situations, however, due to the unfavorable angiographic anatomy precluding safe transcatheter embolization, direct percutaneous glue injection of the pseudoaneurysm sac may be considered to achieve successful occlusion of the sac. The procedure may be rendered safer by simultaneous balloon protection of the parent artery. We describe this novel treatment modality in a case of inferior pancreaticoduodenal artery pseudoaneurysm in a patient with sickle cell anemia. Although a complication in the form of glue reflux into the parent vessel occurred that necessitated surgery, this treatment modality may be used in very selected cases (where conventional endovascular embolization techniques are not applicable) after careful selection of the balloon diameter and appropriate concentration of the glue-lipiodol mixture.

    We present the first case of in situ replacement of an infected subclavian artery using superficial femoral vein and the fourth reported case of an infected arterial pseudoaneurysm caused by pseudomonas pseudomallei. Sepsis and hoarseness developed in a 58-year-old man after recent travel to Borneo, Indonesia. Indirect laryngoscopy revealed a paralyzed right vocal cord. Computed tomography and arteriography revealed a 6.5-cm pseudoaneurysm of the proximal right subclavian artery. Blood cultures grew pseudomonas pseudomallei. An abnormal cardiac stress test prompted a coronary angiography, which revealed severe coronary artery disease.The patient underwent coronary artery bypass and in situ replacement of the infected subclavian artery pseudoaneurysm with a superficial femoral vein, along with placement of a pectoralis major muscle flap to cover the vein graft. Operative cultures of the pseudoaneurysm grew pseudomonas pseudomallei. The patient was treated with a 6-week course of intravenous ceftazidime and oral doxycycline and then continued on oral amoxicillin-clavulanate. One week after discontinuing intravenous antibiotics, the patient presented to the emergency department with a rapidly expanding, pulsatile mass in the right supraclavicular space. He was taken emergently to the operating room. After hypothermic circulatory arrest was accomplished, the disrupted vein graft and aneurysm cavity were resected and the subclavian artery was oversewn proximally and distally. Parenteral ceftazidime was continued for 3 months and oral amoxicillin-clavulanate (augmentin) was continued indefinitely. There was no evidence of infection clinically or by computed tomographic scan 2 years later. Although autogenous vein replacement of infected arteries and grafts may be successful in the majority of cases, this strategy should probably be avoided when particularly virulent bacteria such as the organism in this case are present.

    A 54-year-old male presented with intermittent massive hemorrhage from recurrent oropharyngeal cancer. The angiogram showed the encasements at the main trunk of the left internal carotid artery (ICA) and external carotid artery (ECA). Transcatheter arterial embolization (TAE) of the ECA with gelatin sponge particles and microcoils was performed. However, hemorrhage recurred several hours after the initial TAE. The second angiogram showed a large pseudoaneurysm of the ICA developing at the encasement on the initial angiogram. As a simple neurologic test, regional cerebral oxygenation (rSO{sub 2}) was assessed with and without manual compression of the common carotid artery (CCA). With compression of the left CCA, the rSO{sub 2} did not change. We therefore performed isolation of the pseudoaneurysm. We embolized proximally and distally to the ICA pseudoaneurysm with microcoils and the pseudoaneurysm disappeared. No major complications occurred and no massive hemorrhage recurred until death from the cancer. TAE was an effective treatment for massive hemorrhage caused by tumor invasion to ICA. Assessment of rSO{sub 2} was a simple and useful neurologic test predicting the cerebral blood flow to prevent complications of TAE.

    Dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable.

The splenic artery is the most common location among the spectrum of potential presentation sites of visceral arteries aneurysms and pseudoaneurysms. Endovascular treatment with the use of coils or stents is the first option due to lower morbidity and mortality than open surgery. Endovascular repair may also lead to complications and patients need to be followed up in order to confirm aneurysm sealing, and exclude late complication.

    Introduction Pseudoaneurysms occur when there is a partial disruption in the wall of a blood vessel, causing a hematoma that is either contained by the vessel adventitia or the perivascular soft tissue. Presentation of case A 32-year-old male presented to the emergency department presented with comminuted fractures in the left zygoma, ethmoids, and the right ramus of the mandible following a gunshot wound. The patient underwent open reduction of his fractures and the patient was discharged on the eighth day after the trauma. Thirteen days after the discharge and 21 days after the gunshot wound, the patient returned to the ER due to heavy nasopharyngeal bleeding that compromised the patency of the patient’s airways and caused hemodynamic instability. Arteriography of the facial blood vessels revealed a pseudoaneurysm of the maxillary artery. Endovascular embolization with a synthetic embolic agent resulted in adequate hemostasis, and nine days after embolization the patient was discharged. Discussion The diagnosis of pseudoaneurysm is suggested by history and physical examination, and confirmed by one of several imaging methods, such as CT scan with contrast. Progressive enlargement of the lesion may lead to several complications, including rupture of the aneurysm and hemorrhage, compression of adjacent nerves, or release of embolic thrombi. Conclusion This case reports the long-term follow up and natural history of a patient with a post-traumatic pseudoaneurysm of the internal maxillary artery and the successful use of endovascular embolization to treat the lesion.

    Background: Traumatic pseudoaneurysm of the internal carotid artery (ICA) is an uncommon but serious complication, and difficult to repair surgically. Minimally invasive endovascular treatment of traumatic injuries of the ICA with a stent graft has become increasingly popular over the past decade. The efficacy of the stent graft appears satisfactory, but most if not all reported studies have involved small patient cohorts (less than 10) with short follow-up periods (less than 3 years). Methods: In this prospective study, 13 patients with traumatic pseudoaneurysm of the ICA were recruited from June 2008 to June 2012. All the patients were examined using whole-brain cerebral angiography and followed up for as long as five years. Willis intracranial vascular stent grafts, manufactured by Shanghai Microport, were chosen as embolism material. Results: All 13 patients achieved good clinical outcome. Pseudoaneurysm recurred in one patient and this patient was treated by balloon occlusion of the parent artery. No patient suffered recurrent bleeding or death. Conclusion: Based on the outcomes of this relatively large cohort and long follow-up period, we believe that stent graft is an optimal therapy for patients with traumatic pseudoaneurysms of the ICA.

    Pseudoaneurysm of the cervical internal carotid artery is a very rare, potentially fatal complication of a neck space infection in children associated with high mortality and morbidity. A 3-year-old boy presented with spontaneous massive epistaxis 45 days after a deep neck space infection caused by a peritonsillar abscess. During nasopharyngeal packing, he evolved with cardiac arrest. Intra-arterial angiography was then performed that revealed a large pseudoaneurysm. Endovascular treatment using detachable balloons achieved complete exclusion of the pseudoaneurysm. The child made an uneventful recovery and was discharged with mild left hemiparesis and no deficit of sensory or cognitive functions. Pseudoaneurysms of the internal carotid artery after a deep neck space infection can be associated with delayed and potentially fatal massive epistaxis. Furthermore, a regional (ie, extranasal) blood vessel should be promptly investigated when there are signs of hypovolemic shock. A high level of suspicion and definitive treatment are essential for successful management of these patients.

    Traumatic intracranial pseudoaneurysms are a rare but severe complication following arterial injury. Pseudoaneurysm formation can occur secondary to blunt or penetrating trauma or iatrogenic injury. We report a case of traumatic pseudoaneurysm secondary to placement of an intracranial pressure (ICP) monitor. A 27-year-old man was involved in a motorcycle accident resulting in multiple intracranial hemorrhages. The patient underwent craniectomy and placement of an ICP monitor. 17 days later he developed dilation of his left pupil, with imaging demonstrating a new hemorrhage in the vicinity of the previous ICP monitor. A cerebral angiogram confirmed a left-sided distal M4 pseudoaneurysm which was treated by n-butyl cyanoacrylate embolization. Intracranial pseudoaneurysm formation following neurosurgical procedures is uncommon. Delayed intracranial hemorrhage in a region of prior intracranial manipulation, even following a procedure as 'routine' as placement of an ICP monitor, should raise the suspicion for this rare but potentially lethal complication.

    The case of a 30-year-old woman with a post-traumatic pseudoaneurysm of the superior mesenteric artery and associated celiac axis occlusion is presented. The patient was successfully treated with celiac artery recanalization and placement of a covered stent within the superior mesenteric artery. Follow-up at 3, 6, and 12 months and 3 years demonstrated patency of the covered stent and continued exclusion of the aneurysm. Although the long-term success of this procedure is unknown this management option should be considered where facilities are available, to reduce the increased morbidity associated with open surgical procedure.

    Summary Background: High-flow priapism is a rare condition characterized by a prolonged and painless erection. Since it may permanently impair erectile function, it must be managed and treated as soon as possible, in order to restore potency. The case we are presenting here was successfully treated by embolizing the penile artery using an autologous clot. Case Report: A case of delayed painless high-flow priapism that occured after blunt straddle-type perineal trauma, that was persistent for more than 30 days is being presented. Doppler ultrasonographic examination of the cavernosal artery revealed a 1.5 cm-diameter pseudoaneurysm at the right cavernosal artery, together with a high-velocity shunt between the two cavernous arteries. Extravasation from the proximal sites of both of the cavernous arteries and a right cavernosal artery pseudoaneurysm was detected on angiography. The patient was successfully treated by embolization of the penile artery with an autologous clot in two sessions with a 3-day interval. Conclusions: This experience along with a survey of the literature made us conclude that embolization of cavernous artery by means of an autologous clot is a very effective procedure and a method of choice for treatment of high-flow priapism and for restoration of penile erectile function. What makes our case even more interesting and important, is the fact that priapism of one month’s duration could well be treated by means of this method. PMID:23807886

    Background: Superficial temporal artery (STA) pseudoaneurysms have been reported in the literature since the mid of seventeenth century from Bartholin, however, there is an increasing number of cases, suggesting a diversity of etiological factors. Among these, traumatic events, even of an iatrogenic nature, have been identified as causative factors for nonspontaneous STA pseudoaneurysms. Regional pain and tenderness, troublesome pulsations of the mass, cosmetic concerns as well as the risk of bleeding warrant a thorough evaluation and a definite interventional approach to the condition. Case Description: A 21-year-old Caucasian male searched medical advice for a growing, tender, and pulsatile mass on his right temple, with isolated and short episodes of lancinating sensations, after sustaining a blunt trauma following a hit with a stick half a year before the admission. Enhanced cranial computed tomography and angiography confirmed the diagnosis of an STA pseudoaneurysm. A direct percutaneous aspiration, as well as ultrasonography, was performed prior to the neurosurgical intervention, with the complete removal of the mass. Conclusions: STA pseudoaneurysms require a careful evaluation and a conclusive approach in order to avoid the risk of a growing mass and other nonremote complications such as bone erosions and bleeding. Different treatment options are available, including endovascular obliteration and embolization, however, surgical removal after ligation of the afferent and efferent segments of the vessel seem to be highly effective.

    Splenic artery aneurysms (SAA) are the third most common intra-abdominal aneurysm. Complications include invasion into surrounding structures often in association with preexisting pancreatic disease. We describe an 88-year-old female, with no history of pancreatic disease, referred with lower gastrointestinal bleeding. CT angiography showed a splenic artery pseudoaneurysm with associated collection and fistula to the transverse colon at the level of the splenic flexure. The pseudoaneurysm was embolised endovascularly with metallic microcoils. Rectal bleeding ceased. The patient recovered well and follow-up angiography revealed no persistence of the splenic artery pseudoaneurysm. SAA rupture results in 29%-50% mortality. Experienced centres report success with the endovascular approach in haemodynamically unstable patients, as a bridge to surgery, and even on a background of pancreatic disease. This case highlights the importance of prompt CT angiography, if endoscopy fails to identify a cause of gastrointestinal bleeding. Endovascular embolisation provides a safe and effective alternative to surgery, where anatomical considerations and local expertise permit. PMID:27559488

    Endovascular stent graft repair of traumatic vessel injuries is gaining worldwide acceptance as a minimally invasive alternative to open surgical repair. However, effective endovascular repair fails if the aneurysm is not completely excluded. Conversion to open surgery may be unavoidable in such cases. Herein we describe the case of a 45-year-old man who was referred to our hospital with a pseudoaneurysm of the proximal brachiocephalic artery caused by biopsy during diagnostic medianoscopy. The pseudoaneurysm was primarily treated by stent-graft implantation into the proximal brachiocephalic artery. As a result of the unfavorable location of the lesion exclusion of the aneurysm failed and the initial therapy had to be extended to open reconstruction of the brachiocephalic artery. A bypass procedure from the aortic arch to the right common carotid artery was performed with reinsertion of the right subclavian artery to exclude the pseudoaneurysm.

    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

    We report our experience with a case of emergent endovascular treatment of a large ruptured pseudoaneurysm of the common iliac artery. A 65-year-old male was admitted to the surgical department in hypovolemic shock, due to active retroperitoneal bleeding. A computerized tomography scan with intravenous contrast revealed a ruptured gigantic pseudoaneurysm of the right common iliac artery, with a maximal diameter of 7 cm and retroperitoneal hematoma. An intraoperative angiogram revealed active extravasation through the neck of the pseudoaneurysm, which was successfully sealed with the placement of a stent graft (Medtronic Endurant(®))limb component. Infection of the pseudoaneurysm sac after one month was successfully treated with catheter drainage. No shortterm relapse occurred. Endovascular management should be part of the basic surgical armamentarium on emergent basis, since it provides a fast and safe solution, especially when a patient's co-morbitities preclude open management and hemodynamic and anatomical status allows endovascular treatment.

    To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management. A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted. Pseudoaneurysms were classified into iatrogenic (associated with biliary endoprosthesis or angioplasty) or spontaneous extrahepatic pseudoaneurysms. Spontaneous and iatrogenic pseudoaneurysms were compared for time from transplant, presenting symptoms, location in the arterial anatomy, and 3-month graft survival. Arterial patency and 6-month graft survival were calculated. Twenty pseudoaneurysms were found (1.1 %, 20/1,857): 9 (0.5 % of transplants, 9/1,857) were spontaneous and 11 (0.6 % of transplants, 11/1,857) were 'iatrogenic' (due to minimally invasive procedures: 4 angioplasty and 7 biliary endoprostheses). Sixty percent (12/20) underwent endovascular management (4 coil embolization and 8 stent-grafts). Technical success was 83 % (10/12) with a mean arterial patency of 70 % (follow-up mean, 4.9; range, 0-18 months). The 1-, 3-, and 6-month graft survival was 70, 40, and 35 %, respectively. Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.

Because of high surgical risk, endovascular approach was decided upon. However, taking hardware across the lesion via the aortic arch provided us with insurmountable difficulties. Therefore, a hybrid approach was resorted to, in which an arteriotomy was done in the carotid artery followed by direct implantation of the stent. We were thus able to create a favorable trade-off between the high surgical risk of a full surgical procedure and the peri-operative benefit of an endovascular approach.

    Less invasive surgery and interventional radiology are relatively new techniques. This case report describes a patient with a distal tibial fracture that was stabilized using minimally invasive osteosynthesis consisting of a precontoured metaphyseal Locking Compression Plate (LCP). Postoperative radiographs showed good alignment of the bone, and the initial postoperative course was uneventful. At the sixth-week follow-up visit after surgery, the patient presented with a pulsating and tender mass on the lower leg that was palpable subcutaneously. Arteriography showed a pseudoaneurysm of the anterior tibial artery. At the same procedure an endovascular stent was placed, thereby excluding the pseudoaneurysm from the main circulation while keeping the vessel lumen patent. At the time of the last visit, 6 months after the operation, the patient was fully weightbearing with normal function of the ankle but with a nonhealing fracture on the x-ray. The dorsalis pedis pulse was equally strong as on the right side. Endovascular treatment with a covered stent proved to be an effective treatment for the described posttraumatic pseudoaneurysm of the anterior tibial artery. This case illustrates a risk of less invasive fracture surgery and at the same time underlines the value of a multidisciplinary approach to complications in trauma surgery. PMID:17414557

    Hepatic artery pseudoaneurysms (HAP) are uncommon, occurring mostly as a complication of trauma (accidental or iatrogenic). Liver abscess rarely causes HAP and multiple HAP associated with cholangitic abscesses have not been reported in the literature. We present a patient of acute necrotizing pancreatitis with stent block cholangitis and multiple cholangitic abscesses who developed hemorrhagic output through drainage catheter in the liver abscess. A multiphasic CT angiography demonstrated three HAP, which were treated with a combination of endovascular coil embolization and percutaneous thrombin injection. The fact that cholangitic abscesses may be associated with pseudoaneurysms should not be neglected, considering the potentially catastrophic complication and relatively easy radiological management. CT angiography permits accurate diagnosis and lays down the roadmap for endovascular procedures. PMID:27081232

    Candida arteritis is an uncommon condition but important to recognize due to the risk of significant morbidity and the difficulty in management of the enduring fungal infection. The authors report a rare case of a man with a femoral artery pseudoaneurysm with persistent Candida albicans infection, as a complication of infective endocarditis. The 23-year-old man, with a history of chronic intravenous drug use and Type I diabetes mellitus, presented with left groin pain, paresthesia of his left foot, and a pulsatile mass in the inguinal region. On imaging, he was found to have a pseudoaneurysm of the left common femoral artery, which later ruptured. Further investigation revealed vegetations on the mitral and aortic valves as well. Initial blood cultures were negative. He underwent multiple surgical interventions including replacement of the mitral and aortic valves and resection of the left common femoral artery with autogenous revascularization. In addition, he was commenced on intravenous antifungal therapy. Postoperatively, he continued to experience significant pain in the left groin and had two episodes of rerupture of the femoral artery that was consequently surgically repaired. Histological examination of the resected valves revealed vegetations with a mixture of fungal elements and bacterial cocci. The femoral artery resection specimens revealed evidence of infectious arteritis and the presence and persistence of C. albicans organisms in subsequent specimens. This case highlights the importance of an accurate diagnosis and aggressive management of fungal mycotic aneurysms in at-risk populations.

    Visceral artery pseudoaneurysms secondary to acute and/or chronic pancreatitis are a relatively common and potentially serious complication. Endovascular techniques are the most currently accepted techniques, given the higher morbidity-mortality of surgery. The thrombosis of the pseudoaneurysm using an ultrasound-guided percutaneous thrombin injection is emerging as a useful option in those cases in which endovascular embolisation is not possible. We present the case of a patient with a pseudoaneurysm of the transverse pancreatic artery secondary to chronic pancreatitis, and successfully treated by administering percutaneous thrombin.

    Background Context Isolated spinal artery aneurysms not associated with vascular malformations are exceedingly rare. Purpose To present a rare case of subarachnoid hemorrhage after thoracic radiculomedullary artery pseudoaneurysm rupture in a patient who abused synthetic cannabinoids and methamphetamines. Study Design Case report. Methods A 41-year-old man with a history of polysubstance abuse presented with acute-onset headache, back pain, and transient bilateral lower-extremity numbness. He reported daily use of the synthetic cannabinoid "Spice." He denied use of other illegal drugs, but laboratory testing was positive for methamphetamines. Magnetic resonance imaging showed a focal hematoma at T2-3, and spinal angiography was negative for vascular abnormalities; however, a follow-up angiogram 6 days later revealed interval development of an irregular dilation of the left T3 radiculomedullary artery originating from the left supreme intercostal artery. Results Surgical trapping and resection of the lesion yielded a good clinical outcome. Conclusions Although two previous case reports have described patients with thoracic radiculomedullary pseudoaneurysm causing spinal subarachnoid hemorrhage (SAH), this is the first reported case associated with synthetic cannabinoids and methamphetamine abuse. Although this diagnosis is exceptionally rare, clinical presentation of SAH with associated back pain and lower-extremity symptoms warrants an aggressive imaging workup. Even in the setting of negative angiography, repeat cerebral and spinal angiograms may be necessary to identify a potentially treatable cause of spinal SAH.

    Objective. To review the literature concerning the management with placement of covered stent-grafts of traumatic pseudoaneurysms of the extracranial internal carotid artery (ICA) resulting from penetrating craniocervical injuries or skull base fractures. Method. We have reviewed, from the Medline database, all the published cases in the English literature since 1990 and we have added a new case. Results. We identified 20 patients with traumatic extracranial ICA pseudoaneurysms due to penetrating craniocervical injuries or skull base fractures who had been treated with covered stent-graft implantation. Many discrepancies have been ascertained regarding the anticoagulation therapy. In 3 patients the ICA was totally occluded in the follow-up period, giving an overall occlusion rate 15%. No serious complication was reported as a result of the endovascular procedure. Conclusion. Preliminary results suggest that placement of stent-grafts is a safe and effective method of treating ICA traumatic pseudoaneurysms resulting from penetrating craniocervical injuries or skull base fractures. The immediate results are satisfactory when the procedure takes place with appropriate anticoagulation therapy. The periprocedural morbidity and mortality and the early patency are also acceptable. A surveillance program with appropriate interventions to manage restenosis may improve the long-term patency.

    Pancreatitis is a known cause of pseudoaneurysms of the peripancreatic arteries, which can rarely rupture into various adjacent structures and become a source of life-threatening bleeding. The management is challenging and requires an individualised approach and multidisciplinary care. Herein, we present the case of a 24-year-old man in whom a splenic pseudoaneurysm ruptured into the adjacent infected pseudocyst, communicating with the colon by a fistulous tract, causing massive lower gastrointestinal bleeding. This was successfully managed by transcatheter arterial embolisation (TAE).

    We report on a 55-year-old woman with recurrent chronic pancreatitis complicated by a 7-cm splenic artery pseudoaneurysm. A therapeutic endovascular treatment was chosen because of the patient's high surgical risk. Initial embolization with fibered coils succeeded in thrombosing the aneurysm lumen, but the aneurysm neck remained patent. Further embolization was achieved with two detachable Gugliemi Detachable Coils (GDCs) deployed across the aneurysm neck, successfully thrombosing the residual aneurysm. GDCs complement the more thrombogenic traditional fibered coils and should be used advantageously in critical locations to embolize difficult splenic artery pseudoaneurysms.

    Vertebral artery injury including thrombosis, arteriovenous fistula (AVF), pseudo-aneurysm and hemorrhage may be iatrogenic or due to penetrating or blunt trauma. Although mostly asymptomatic, vertebral artery injury may also present with vertebrobasilar insufficiency findings, cephalgia, radicular pain or myelopathy due to blockade of arterial flow, arterial steal phenomenon and venous hypertension. The gold standard for diagnosis is digital subtraction angiography (DSA). Doppler ultrasonography, magnetic resonance-angiography and computerized tomography-angiography are also helpful. Endovascular treatment is now used more commonly. We present a case with sharp bread knife injury of the vertebral artery that was also complicated with a vertebrojugular fistula and pseudo-aneurysm together with the diagnostic and management options and a review of the current literature.

    Background: Spontaneous superficial temporal artery (STA) pseudoaneurysms are very rare; only four cases, including ours, have been reported to date. Therefore, the cause of them has not been studied. Case Description: A 57-year-old woman was admitted to our hospital with a pulsatile mass in the left preauricular region. Her medical history included hypertension, dyslipidemia, and angina pectoris. She denied a history of head injury or minor head trauma. Three-dimensional computed tomography angiography showed a well-enhanced saccular aneurysm on the main trunk of the STA. To prevent rupture it was removed surgically. The histological diagnosis was pseudoaneurysm with atherosclerosis. By the 2nd postoperative day, she had completely recovered and was discharged home. There has been no relapse. Conclusions: As all four documented patients were at high risk for atherosclerosis, we posit that a causal factor was weakening of the arterial wall due to atherosclerosis and chronic pressure on the STA from anatomical structures. Here, we present histological evidence to support this hypothesis. PMID:27127716

    A serious complication of laparoscopic sleeve gastrectomy (LSG) is bleeding that is primarily located along the staples lines. Bleeding may be due to several causes, including hematomas, trocar sites, or visceral pseudo-aneurysms. We reported here a case of bleeding related to a pseudo-aneurysm of the gastro-omental artery. An LSG was performed on a 43-year-old woman (BMI = 46 kg/m2) without apparent surgical complications. Fifteen days later, she was admitted to the emergency department for hematemesis and symptoms of hemorrhagic shock. Abdominal computed tomography angiography revealed blood in the stomach, without a digestive leak, and active bleeding from a pseudo-aneurysm of the gastro-omental artery. An arterial embolisation was performed with the sandwich technique and angiographic guide wires and the placement of several detachable coils. The patient was discharged two days later. We demonstrated for the first time that post-LSG bleeding may involve a pseudo-aneurysm of the gastro-omental artery.

    Background: Dissecting giant pseudoaneurysm of the middle cerebral artery (MCA) is a rare lesion often presenting challenges to neurosurgical teams dealing with this specific pathology. Giant pseudoaneurysm originating from a dissecting distal segment of the MCA treated with aneurysm trapping under motor and sensitive evoked potential monitoring with a successful outcome is presented in the article followed by a brief discussion on the subject. Case Description: A case of a previously healthy young female patient admitted at the emergency room of Santa Paula Hospital with a history of a sudden headache and syncope, dysphasia, and Grade 4 right hemiparesis due to a large brain hemorrhage secondary to a 25 mm ruptured pseudoaneurysm originated from a distal left MCA dissecting segment is described. Because the patient risked neurological worsening, aneurysm was treated with parent and efferent vessel trapping technique and no changes on the sensitive and motor evoked potential (MEP) from baseline informed on this decision. Hemorrhage was completely drained after aneurysm was secured. Conclusion: Neurophysiological sensitive and MEP monitoring, on this specific case was a valuable tool and informed on the decision of trapping of this large vascular lesion. PMID:27127710

    Large cerebral aneurysms of the basilar apex are difficult to treat. Recently, endovascular treatment has mitigated much of the morbidity associated with treating these lesions. However, the morphology of aneurysms of the vertebrobasilar system can preclude endovascular treatment. Rapid ventricular pacing (RVP) facilitates open surgical treatment of cerebral aneurysms. It can assist in reducing the pressure of the neck of the aneurysm, allowing safe application of a clip. The authors present a case of a pediatric patient who developed a basilar artery pseudoaneurysm that required surgery. Given the large size of the aneurysm, RVP was performed, allowing the surgeons to dissect the dome of the aneurysm from the surrounding tissue and pontine perforating branches away from the lesion to safely clip the lesion. The patient had an uneventful recovery. To the authors' knowledge, this represents the first known case of RVP to aid in basilar artery clip occlusion in a pediatric patient.

    Sudden deafness is acute onset of impaired hearing which develops within hours to few days. The commonly accepted audiometric criterion is a decrease in hearing of ≥ 30 dB, affecting at least three consecutive frequencies. Hearing loss is thought to involve several causative factors, including internal ear circulatory disturbances. We report the case of a female with an internal carotid artery (ICA) pseudoaneurysm in the distal cervical tract and unilateral sudden sensorineural hearing loss (SSNHL). As putative risk vascular factor, the patient had history of migraine since youth. Extensive screenings for autoimmune, rheumatic diseases, virological, and microbiological infections were negative. The patient denied recent cervical trauma. Furosemide and oral prednisone were given with initial benefit and withdrawn in 3 weeks. The patient experienced short-lasting episodes of headache, tinnitus, vertigo. Five weeks after first onset, she underwent magnetic resonance imaging (MRI) angiogram which revealed fusiform dilatation of left ICA in the cervical tract. It can be proposed, but it remains to be proved, that the pseudoaneurysm of the cervical ICA plays a role in the patient SSNHL in relation to turbulent flow or thromboembolism of branches to the inner ear.

Two patients (a 69-year-old man and an 83-year-old man) were admitted to our hospital because of acute cholecystitis with gallstone impaction in the neck. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed for both patients. After a few days of PTGBD, gallbladder hemorrhage was observed. Abdominal angiography showed cystic artery aneurysm. A transcatheter arterial embolization was therefore performed, followed by an open cholecystectomy. PMID:27593367

    A 48-year-old woman with severe juvenile-onset rheumatoid arthritis presented with a bleeding cutaneous sinus distal to her right total hip replacement scar. Methicillin resistant Staphylococcus aureus (MRSA) was isolated on culture. She had previously undergone bilateral total hip and knee replacements at aged 23 and six years later had the right knee prosthesis removed for infection, with subsequent osteomyelitis of the femoral shaft and right total hip prosthesis disruption. Peripheral arteriography was performed in view of persistent bleeding from the sinus, which revealed a 6 cm false aneurysm filling from and compressing the right external iliac artery (EIA). A PTFE-covered, balloon expandable JOSTENT was deployed in the right EIA, successfully excluding the false aneurysm and preventing further bleeding from the sinus. No graft infection was reported at 12 months. This case illustrates the potential use of endovascular stent-grafting in the treatment of an infected pseudoaneurysm.

Emergency stent-grafting appears to be a viable, minimally invasive alternative, or a bridge, to subsequent open surgery. Caution is required in cases of suspected concomitant deep vein thrombosis in order to minimize the possibility of massive pulmonary embolism during stent-grafting, perhaps by omitting stent-graft postdilation or by inserting an inferior vena cava filter first. We describe the emergency endovascular management, in a 60-year-old male intravenous drug abuser, of a ruptured mycotic femoral artery pseudoaneurysm, which was complicated by a fatal pulmonary embolism.

    Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

    The use of percutaneous angioplasty with subsequent intravascular metallic stent placement has gained increasing acceptance over the past decade. Infections of these stents appear to be uncommon; however, the rarity of this complication may in part be the result of a lack of availability of long-term follow-up data. A number of examples of infected cardiac and peripheral vascular stents have been reported, often with fatal consequences. Herein, we report a 74-year-old woman who underwent subclavian and brachiocephalic artery angioplasty and stent placement for symptomatic stenoses. Six months after the initial intervention, the patient returned with restenosis of the stents and underwent repeat angioplasty to restore full patency. Two weeks later, the patient was readmitted with generalized malaise and multiple erythematous, macular lesions on the right forearm and hand. Blood cultures grew Staphylococcus aureus, and a computed tomographic scan of the chest showed a large brachiocephalic artery pseudoaneurysm with surrounding hematoma. Despite prompt surgical intervention, this complication proved ultimately fatal. Infections of metallic endovascular stents are potentially life-threatening complications and must be addressed urgently, including possible surgical intervention. PMID:12218990

    An 82-year-old woman developed acute occlusion of her right coronary artery. She underwent percutaneous coronary stent placement and aortic balloon pump installation. In the postprocedural period, she developed a common femoral artery pseudoaneurysm (PSA) that communicated with the common femoral vein via an arteriovenous fistula (AVF). After unsuccessful ultrasound-guided compression, ultrasound-guided thrombin injection of the PSA was performed, with simultaneous balloon occlusion of the common femoral vein at the level of the AVF. There was complete thrombosis of the PSA and AVF.

    Mycotic false aneurysm caused by local arterial injury from attempted intravenous injections in drug addicts remains a challenging clinical problem. The continued increase in drug abuse has resulted in an increased incidence of this problem, particularly in high-volume urban centres. In the drug-abusing population, mycotic arterial pseudoaneurysms most often occur because of missed venous injection and are typically seen in the groin, axilla, and antecubital fossa. Mycotic aneurysms may lead to life-threatening haemorrhage, limb loss, sepsis, and even death. Any soft-tissue swelling in the vicinity of a major artery in an intravenous drug abuser should be suspected of being a false aneurysm until proven otherwise and should prompt immediate referral to a vascular surgeon for investigation and management. We report a case of rupturing mycotic pseudoaneurysm of the left common femoral artery treated by surgical resection followed by vessel reconstruction with autologous material. Unfortunately, at the time of discharge a sudden leakage from the vein graft anastomosis occurred, with subsequent massive bleeding, and required emergent endovascular covered stenting. To the best of our knowledge, this is the first reported case of femoral artery bleeding in a drug abuser treated by stent graft placement.

    Introduction Symptomatic hepatic-artery pseudoaneurysm (HAP) after bile-duct injury (BDI) is a rare complication with a varied (but clinically urgent) presentation. Methods A prospectively maintained database of all patients with BDI at laparoscopic cholecystectomy (LC) referred to a tertiary specialist hepatobiliary centre between 1992 and 2011 was searched systematically to identify patients with a symptomatic HAP. Care and outcome of these patients was studied. Results Eight (6 men) of 236 patients with BDI (3.4%) with a median age of 65 (range: 54?6) years presented with symptomatic HAP. Median time of presentation of the HAP from the index LC was 31 (range: 13?16) days. Bleeding was the dominant presentation in 7 patients. One patient presented late (>2 years) with abdominal pain alone. Computed tomography angiography was the most useful investigation. Angioembolisation was successful in 7 patients. One patient died, and another patient developed liver infarction. Three patients (38%) developed biliary strictures after embolisation. Seven patients are alive and well at a median follow-up of 66 months. Conclusions Presentation of HAP is often delayed. A high index of suspicion is necessary for the diagnosis. Computed tomography angiography is the first-line investigation and selective angioembolisation can yield successful outcomes. PMID:27580308

    Acute or chronic blood loss from pseudoaneurysms of the splanchnic artery in chronic pancreatitis poses diagnostic and management challenges. Arteriographic examination offers both diagnostic and therapeutic options, with success rates of 76%-100% for both modalities. In cases of failure of embolization, repeat embolization is also an option. Surgical intervention is advocated for rebleeding and failure of embolization. Evidence-based guidelines regarding the optimal treatment modality for this condition are lacking. There has been a reported case of dislodgement of coil into the stomach through a gastropseudocystic fistula. We report the case of a migrating steel-wire coil through the gastrointestinal tract and splenic artery pseudoaneurysm. We highlight the potential complications of pseudoaneurysm and other available therapeutic management options.

    We report three cases of hepatic artery pseudoaneurysm, which were all treated successfully using a combination of coil embolization and a side-holed 5F indwelling catheter for maintaining minimal hepatic artery blood flow with exclusion of the pseudoaneurysm. The tip of an infusion catheter was placed in the right hepatic artery and a side hole was positioned at the celiac axis. Coil embolization was then performed from the proper to the common hepatic artery using detachable coils. Hemostasis was achieved in all patients, with a final angiogram showing the hepatic arteries through the indwelling catheter. One major hepatic infarction and one focal liver abscess caused by reflux cholangitis manifested on postoperative days (PODs) 11 and 87, respectively. All patients survived and the indwelling catheter was removed on POD 136–382 without complication.

    The diagnostic value of common ultrasound and contrast-enhanced ultrasonography (CEUS) in hepatic artery pseudoaneurysm (HAP) after liver transplantation was investigated. From January 2005 to November 2015, information was collected on 2,085 cases of orthotopic liver transplantation. The cases included 1,617 men and 468 women. Common ultrasound and CEUS were used to monitor arterial blood flow following surgery, and the complications were assessed. Instruments used included Acuson Sequoia 512 and Mylab Twice, and the contrast agent was SonoVue. The standard of common ultrasound in the diagnosis of HAP was follicular structure, which had arterial blood flow signal present beside the hepatic artery. The diagnostic criteria of HAP using CEUS were abnormal and round contrast enhancement zone and perfusion of the contrast agent in the zone near the hepatic artery. The diagnostic standard of HAP was computed tomographic angiography (CTA) and emergency operation. Eight cases of HAP were diagnosed in 2,085 patients after liver transplantation (0.38%). Three cases of HAP were diagnosed successfully by common ultrasound while 5 cases were missed. Sensitivity, specificity and diagnostic accuracy for common ultrasound was 37.5, 100 and 99.76%, respectively. Six cases of HAP were diagnosed by CEUS and 2 cases were missed. Sensitivity, specificity and diagnostic accuracy for CEUS was 75, 100 and 99.9%, respectively. Collectively, CEUS is a convenient and effective diagnostic method for HAP following liver transplantation, the diagnostic sensitivity was obviously higher than that of the common ultrasound, and it was more convenient than CTA. Nevertheless, the diagnosis of pseudoaneurysm with deep location, and unsatisfactory grayscale images were easily missed. PMID:27446316

We report on a patient who developed an ascending aortic pseudoaneurysm after aortic valve replacement (AVR), which was treated successfully with endovascular therapy. Our case showed that angulation of the ascending aorta is one of factors for consideration in application of endovascular therapy and endovascular therapy might be an option for management of ascending aortic pathology in patients with high surgical risk, particularly patients with a severely angulated proximal ascending aorta.

    Acute intracranial pseudoaneurysms secondary to aneurysmal rupture are a rare entity with no clear evidence-based guidelines for treatment to our knowledge. There are numerous examples of successful treatment of pseudoaneurysms both surgically and endovascularly, the latter mainly within the anterior circulation. Risk of pseudoaneurysm rupture in the acute state during endovascular procedures with subsequent difficulty in controlling the bleeding without sacrificing the feeder artery has led to some reservation in using endovascular treatments more broadly. We report a rare case of a 52-year-old-woman who presented with acute subarachnoid hemorrhage and was found to have a ruptured 5 mm × 8 mm bi-lobulated basilar apex aneurysm on CT angiography. Digital subtraction angiography demonstrated an associated anterior pseudoaneurysm that was formed secondary to the aneurysm rupture. The true aneurysm was successfully coiled with careful avoidance of the pseudoaneurysmal sac. Pseudoaneurysms are frequently identified for the first time during digital subtraction angiography. Recognizing their presence is essential for treatment planning. Acute pseudoaneurysms associated with true aneurysmal rupture can be safely and successfully treated by endovascular coiling of the true aneurysm. Care must be taken to avoid manipulation of the pseudoaneurysmal sac during the embolization.

    Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

    Objective: To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. Methods: This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm) and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Results: Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55%) men and 9 (45%) women. Nine (45%) patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85%) patients and 3 (15%) were managed conservatively. Conclusion: End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury.

    Rupture of a uterine artery pseudo-aneurysm during pregnancy is a rare condition with potential life-threatening complications, and management should take into account the fetal impact of the therapeutic choice. We report the case of a 2cm left uterine artery pseudo-aneurysm revealed by pelvic pain, in a 30-year-old pregnant woman at 26(+0)weeks of gestation (WG). Diagnosis was suspected at ultrasound scan, and confirmed with Magnetic Resonance angiography that showed signs of pre-rupture. An emergency selective embolization attempted in utero allowed the complete exclusion of the aneurysmal sac. The patient gave birth one month later to a girl at 31(+1)WG, initially managed by neonatologists, who is currently in good health.

    Activated pancreatic enzymes due to pancreatitis track along anatomic fascial planes and result in digestion of the surrounding tissues and pseudocyst formation. Pancreatic pseudocysts can cause variable complications in some cases. Abdominal contrast-enhanced CT scan can provide a valuable method to identify pancreatic pseudocyst and its related complications, especially in evaluating the adjacent vascular involvement. Splenic arterial pseudoaneurysm ruptured into pancreatic pseudocyst together with fistulous communication with the colon is a very rare condition. So, here we report such an additional case with abruptly acute lower gastrointestinal bleeding on his admission, who was finally diagnosed to be splenic arterial pseudoaneurysm ruptured into pancreatic pseudocyst coexisting with fistula to the colon by contrast-enhanced CT scan and treated successfully by urgent surgery.

She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm. This was treated with an endovascular stent resulting in slightly improved motor function, but the significant residual deficit required subsequent rehabilitation to improve right upper limb function.

    Rupture of the aorta is a relatively rare complication of blunt chest trauma, and traumatic rupture of the aortic valve is even rarer. Even though both result from blunt chest trauma, the causative mechanisms of aortic valve injury differ from those of descending aortic rupture. There are no previous reports in the literature of simultaneous injuries to both the descending aorta and the aortic valve. We report a case of a 70-year-old man who presented with traumatic aortic regurgitation combined with traumatic pseudoaneurysm of the aortic isthmus following blunt chest trauma, and its successful repair with a hybrid surgical strategy.

    Patient: Male, 77 Final Diagnosis: Femoral artery pseudoaneurysm Symptoms: None Medication: — Clinical Procedure: Cardiac catheterization and coronary stenting with Starclose vascular closure Specialty: Interventional Cardiology Objective: Educational Purpose (only if useful for a systematic review or synthesis) Background: Vascular closure devices (VCDs) are frequently used for hemostasis with endovascular procedures by employing sutures or plug devices (using collagen or hydrogel) or through the use of a metal clip made of nickel and titanium, such as the StarClose SE device. In comparison to manual compression (MC), VCDs are associated with earlier time to discharge and ambulation, improved patient comfort, and better cost-effectiveness. Case Report: A 77-year-old man with history of ischemic cardiomyopathy with non-ST segment elevation myocardial infarction (NSTEMI) underwent diagnostic cardiac catheterization with deployment of a StarClose SE vascular closure device for hemostasis. Upon repeat access 4 days later for coronary intervention, retrograde sheath angiography revealed a pseudo-aneurysm emanating from the center of the StarClose clip. Conclusions: A review of the literature shows VCDs to be non-inferior to MC, with an overall high success rate. Major and minor complications rates are comparable to those with MC, and pseudo-aneurysm is an infrequent complication. PMID:27026227

    A pseudoaneurysm refers to a defect in the arterial wall, allowing communication of arterial blood with the adjacent extra-luminal space. Pseudoaneurysms result from traumatic arterial injury. With the increasing utilization of percutaneous arterial interventions, iatrogenic arterial injury has become the predominant cause of pseudoaneurysm formation. Rupture of the pseudoaneurysm comprises a vascular emergency. Clinical suspicion and imaging techniques are the cornerstones of timely diagnosis and appropriate management of the condition. Herein, we report the case of a 69 year-old woman who suffered a life-threatening profunda femoral artery pseudoaneurysm rupture after a routine cardiac catheterization, that was treated surgically.

    The study was aimed at analysing strategies of prevention of puncture-related complications in patients with myocardial infarction undergoing subjected to emergency coronary interventions by means of a femoral arterial access. We carried out a retrospective comparative analysis of two strategies aimed at preventing false aneurysms of femoral arteries: Group One (232 cases) - elective use of special devices for closure of puncture defects in patients with high risk of haemorrhage (previously performed thrombolytic therapy; exogenous obesity of the second-third degree, 2-3 degree arterial hypertension, use of 2b/3a blood platelet receptors inhibitors); Group Two (525) cases - conventional routine use of these technologies. Puncture defects were closed using by means of devices Cordis Exoseal and St.Jude Angio-Seal. The obtained results suggested advantage of the conventional approach: demonstrating a statistically significant (p < 0.05) decrease in the total incidence of false aneurysms of femoral arteries (from 5.2 to 1.9%) and the frequency of cases requiring surgical suturing of the defect in the femoral artery (from 1.7 to 0.2%). In the conditions of an intensive flow of emergency patients presenting with acute coronary pathology and requiring coronary interventions, devices for closing defects in the femoral arterial access make it possible to level puncture complications. Over the examined period of 2013-2014 there were performed more than 600 closures of defects of the femoral artery by means of the Cordis ExoSeal. These devices proved to be efficient, reliable, and very simple to use. A decrease in the incidence rate of puncture-related complications was also associated with rational prescription administration of drugs influencing positively various links of haemostasis.

    We report a rare case of spontaneous extracranial cervical internal carotid artery (ICA) pseudoaneurysm in a female child aged 3 years who presented with a swelling in the neck which had bled following an attempted incision as it had been thought to be an abscess. A CT angiogram and an MR angiogram were not very conclusive to diagnose the exact site of origin and the morphology of the aneurysm. Digital subtraction angiography revealed a dissecting pseudoaneurysm of the right extracranial cervical ICA. The right ICA was ending as a pseudosac, and the right cerebral circulation was filling up through the right posterior cerebral artery. To minimize the radiation exposure, a microcatheter was placed inside the diagnostic catheter. The aneurysm sac was occluded using N-butyl cyanoacrylate since there was no distal flow to the brain from the artery beyond the aneurysm. It was a safe, effective and cheaper alternative to open surgery or to other endovascular management options available. Not all neck swellings are abscesses, and they should be examined and evaluated to exclude a vascular cause.

    Kommerell's diverticulum is an aortic arch deformity associated with an aberrant subclavian artery. Symptoms related to compression of adjacent structures, dilatation of the aortic diverticulum or accelerated atherosclerosis leading to increased risks of dissection and rupture represent the indications for surgical treatment. Several surgical strategies have been used for the management of this congenital abnormality. We present the case of a 56-year-old male with a pseudo-aneurysm of a left aortic arch adjacent to a Kommerell's diverticulum at the orifice of a left subclavian artery. The patient also presented an aberrant right subclavian artery originating from the posterior wall of the ecstatic take-off of the left subclavian artery. Our surgical strategy was limited to the resection of the aneurysm without any manipulation of the aortic diverticulum and aberrant right subclavian artery, as the wall of both aorta adjacent to the saccular aneurysm and left subclavian artery was normal, the Kommerell's diverticulum was small and the patient was asymptomatic.

    Genetic defects in the plasma membrane-associated sarcoglycan complex produce cardiomyopathy characterized by focal degeneration. The infarct-like pattern of cardiac degeneration has led to the hypothesis that coronary artery vasospasm underlies cardiomyopathy in this disorder. We evaluated the coronary vasculature of gamma-sarcoglycan mutant mice and found microvascular filling defects consistent with arterial vasospasm. However, the vascular smooth muscle sarcoglycan complex was intact in the coronary arteries of gamma-sarcoglycan hearts with perturbation of the sarcoglycan complex only within the adjacent myocytes. Thus, in this model, coronary artery vasospasm derives from a vascular smooth muscle-cell extrinsic process. To reduce this secondary vasospasm, we treated gamma-sarcoglycan-deficient mice with the calcium channel antagonist verapamil. Verapamil treatment eliminated evidence of vasospasm and ameliorated histological and functional evidence of cardiomyopathic progression. Echocardiography of verapamil-treated, gamma-sarcoglycan-null mice showed an improvement in left ventricular fractional shortening (44.3 +/- 13.3% treated versus 37.4 +/- 15.3% untreated), maximal velocity at the aortic outflow tract (114.9 +/- 27.9 cm/second versus 92.8 +/- 22.7 cm/second), and cardiac index (1.06 +/- 0.30 ml/minute/g versus 0.67 +/- 0.16 ml/minute/g, P < 0.05). These data indicate that secondary vasospasm contributes to the development of cardiomyopathy and is an important therapeutic target to limit cardiomyopathy progression.

    Internal carotid artery pseudoaneurysm is a rare life-threatening condition that may develop in different clinical situations. We report the case of an extracranial internal carotid artery pseudoaneurysm secondary to a throat infection in a pediatric patient that was initially treated with percutaneous thrombin injection under ultrasound guidance. However, recanalization occurred at 48 h, and definitive treatment was then performed by endovascular stent-graft placement. We briefly review the clinical characteristics of this uncommon clinical condition as well as the treatment options.

    A 16-year-old male patient with hereditary multiple exostoses (HME) was found to have a pseudoaneurysm of the left popliteal artery caused by osteochondroma in the lower femur. The diagnosis was confirmed by ultrasound, magnetic resonance imaging and magnetic resonance angiography without the need to perform an angiogram. The osteochondroma was excised and the popliteal artery was repaired with a saphenous graft. Vascular complications are extremely rare in HME, pseudoaneurysm being the most common and mostly located in the popliteal artery. This complication should be considered in young HME patients with a mass at the knee region. The radiological spectrum of investigations allows the diagnosis of this complication with proper and less invasive management procedures for the patient.

    Pancreatic pseudoaneurysm is a relatively uncommon complication of chronic pancreatitis, with an associated high mortality if rupture or hemorrhage occurs. We present a case of pancreatic pseudoaneurysm complicating pancreatitis which was successfully treated by direct percutaneous injection of thrombin into the aneurysmal sac. Follow-up at 8 weeks did not demonstrate recurrence. This case indicates that percutaneous thrombin injection offers effective treatment of visceral arterial pseudoaneurysms.

    Traumatic STA aneurysm is a rare complication of facial trauma occuring typically in young men. We present the case of a minor league baseball player who developed 2 pseudoaneurysms after being struck by a baseball and review all cases associated with sports activities. Reports associated with sports activities are increasing and may represent an increasing incidence. The team physician should suspect this condition when a player presents with a new temporal mass after facial trauma. Diagnosis is typically made on history and physical examination, but can be confirmed by duplex ultrasound. Definitive treatment is surgical resection of the aneurysm after proximal and distal ligation of the vessel.

    Identifying extra spinal causes of a lumbar radiculopathy or polyneuropathy can be a tricky diagnosis challenge, especially in children. Among them, traumatic or iatrogenic pseudoaneurysms of iliac arteries have been seldom reported, in adults' series. The authors report an unusual case of progressive paralyzing left sciatica and lumbar plexopathy in a 12 years old boy, 12 months after a pelvic osteotomy for bilateral hip luxation secondary to osteochondritis dissecans. Spine MRI and pelvic CT angiography revealed a giant internal iliac artery pseudoaneurysm, enclosed in a chronic hematoma. The patient was successfully treated with endovascular coil embolization, and subsequent surgical hematoma evacuation. However, three months after treatment, neurological recovery was incomplete. This case highlights the importance of a rapid and extensive diagnosis work up of all causes of lower limb radiculopathies in children, including pelvic arteries lesions especially after pelvic surgery to avoid therapeutic delays that may jeopardize the chances of neurological recovery.

    Objective Traumatic pseudoaneurysms are rare but life-threatening lesions. We investigated the patients with these lesions to clarify their clinical characteristics and therapeutic strategies and we also reviewed the literatures on the treatment principles, possible options, and outcomes. Methods There were a total of 8 patients who were treated with traumatic intracranial pseudoaneurysms between April 1980 and January 2009. Medical charts and the imaging studies were reviewed for analysis. The outcome was measured with modified Rankin Scale (mRS) score at 6 months after treatment. Results All 8 patients were male and the mean age was 25 years old. Six of those were located at the cavernous segment of the internal carotid artery (ICA) and the other 2 was located at the M2 segment of middle cerebral artery. The causes of trauma were car accidents in 6, penetrating injury through the orbit in 1, and slip down injury in 1 patient. Massive epistaxis or hematemesis occurred in all patients with a pseudoaneurysm at the cavernous and ophthalmic segment of the ICA. All 6 patients of the cavernous and ophthalmic ICA group showed favorable outcome of mRS 0 to 1. The outcome of patients with middle cerebral artery pseudoaneurysm was mRS 2 to 3. Conclusion Upon prompt diagnosis and proper treatment planning, it is possible to achieve favorable outcome in these patients. Lesions located at the cavernous segment of the ICA favored endovascular treatment while those at the middle cerebral artery favored surgical treatment. PMID:27169077

    A femoral artery pseudoaneurysm is one complication of vascular intervention, and the incidence is increasing. Early management is then needed to avoid potential dangers from it. It differs from a true aneurysm in that it doesn't include any component of the vascular wall, and is not studied as much as a true aneurysm. Here, a model of a femoral pseudoaneurysm was made and a Computational Fluid Dynamics(CFD) simulation was verified with PIV experiment. Afterwards, a CFD simulation with two different models was performed to look for any findings which may help in developing new treatment methods.

    Endocrine hypertension offers a potentially curative therapy if the underlying cause is identified and treated accordingly. In contrast to the high prevalence of arterial hypertension especially in the elderly, the classical endocrine causes remain a rare entity. Among patients with arterial hypertension the prevalence of Cushing's syndrome or pheochromocytoma is less than 1%. Primary hyperaldosteronism is more frequent with a reported prevalence of up to 9%. In order to avoid unnecessary, costly and potentially harmful evaluations and therapies due to the limited sensitivity and specificity of the critical endocrine tests it is mandatory to limit the exploration for endocrine causes to preselected patients with high pretest probability for an endocrine disorder. Younger age at manifestation of arterial hypertension or drug resistant hypertension together with other clinical signs of an endocrine disorder should raise the suspicion and prompt the appropriate evaluation.

    Objective To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudoaneurysms presenting as intractable epistaxis. Materials and Methods For 14 consecutive patients with traumatic pseudoaneurysm presenting as refractory epistaxes, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudoaneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (ICA); out of which, two were managed with detachable balloons, two with covered stents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Results Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from ICA pseudoaneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. Conclusion In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudoaneurysms. PMID:21076585

    A 67-year-old woman resented with an acute type A aortic dissection, which was treated surgically with aortic valve replacement as a composite graft with reimplantation of the coronary arteries. At the end of surgery, a left-ventricular venting catheter was placed through the apex and closed with a buffered suture. Consecutive computed tomography (CT) examinations verified a growing apex pseudoaneurysm. Communication between the ventricle and the pseudoaneurysm was successfully closed with an Amplatz septal plug by the transfemoral route. Follow-up CT showed an additional pseudoaneurysm, which also was successfully closed using the same method.

    A 74-year-old man presented with a ruptured infected anastomotic femoral pseudoaneurysm. Due to severe medical comorbidities he was considered unsuitable for conventional surgical management and underwent an emergency endovascular repair with a balloon-expandable covered stent. The pseudoaneurysm was excluded successfully and the patient had an uneventful postoperative recovery with long-term suppressive antimicrobials. He remained well for 10 months after the procedure with no signs of recurrent local or systemic infection and finally died from an acute myocardial infarction. To our knowledge, emergency endovascular treatment of a free ruptured bleeding femoral artery pseudoaneurysm has not been documented before in the English literature. This case illustrates that endovascular therapy may be a safe and efficient alternative in the emergent management of ruptured infected anastomotic femoral artery pseudoaneurysms when traditional open surgery is contraindicated.

    Pseudoaneurysm resulting from hysteroscopic myomectomy is a rare clinical situation, and interventional radiologists are not traditionally involved in the management. To our knowledge, endovascular treatment of a pseudoaneurysm resulting from hysteroscopic myomectomy has not yet been reported in the English-language literature. Here, two such cases are reported, including one of a woman who later became pregnant. The case is unique because little is known about the influence of unilateral coil embolization of the uterine artery on fertility.

    The aim of this study was to review all cases of pseudoaneurysm in the literature, in predominantly arthroscopic procedures on the knee, and to report on a case of pseudoaneurysm that we treated. A bibliographic search was conducted for scientific articles published in Brazilian and foreign periodicals over the last 23 years. Forty-seven cases were found, in 40 articles. In addition to these 47 cases, there was the case that we treated, which was also included in the data. Among the operations that progressed with formation of a pseudoaneurysm, 60% were cases of meniscal injuries and 23%, anterior cruciate ligament injuries. In 46% of the cases, the artery affected with the popliteal, and in 21%, the inferomedial genicular artery. The commonest clinical symptom was pain (37%), followed by pulsating tumor (31%), edema of the calf (12%) and hemarthrosis (11%). The median time taken to make the diagnosis was 11 days, but it ranged from one day to 10 weeks after the procedure. Although rare, pseudoaneurysms are a risk that is inherent to arthroscopic surgery. All patients should be made aware of the vascular risks, even in small-scale procedures.

  17. Secondary arterial hypertension: when, who, and how to screen?

    Secondary hypertension refers to arterial hypertension due to an identifiable cause and affects ∼5-10% of the general hypertensive population. Because secondary forms are rare and work up is time-consuming and expensive, only patients with clinical suspicion should be screened. In recent years, some new aspects gained importance regarding this screening. In particular, increasing evidence suggests that 24 h ambulatory blood pressure (BP) monitoring plays a central role in the work up of patients with suspected secondary hypertension. Moreover, obstructive sleep apnoea has been identified as one of the most frequent causes. Finally, the introduction of catheter-based renal denervation for the treatment of patients with resistant hypertension has dramatically increased the interest and the number of patients evaluated for renal artery stenosis. We review the clinical clues of the most common causes of secondary hypertension. Specific recommendations are given as to evaluation and treatment of various forms of secondary hypertension. Despite appropriate therapy or even removal of the secondary cause, BP rarely ever returns to normal with long-term follow-up. Such residue hypertension indicates either that some patients with secondary hypertension also have concomitant essential hypertension or that irreversible vascular remodelling has taken place. Thus, in patients with potentially reversible causes of hypertension, early detection and treatment are important to minimize/prevent irreversible changes in the vasculature and target organs.

    We present the case of a late superficial femoral artery stent disconnection causing an asymptomatic pseudoaneurysm successfully treated with a stent-graft. A 67-year-old female was referred to our department for evaluation of claudication of the left lower limb and was diagnosed to have a total occlusion of the superficial femoral artery. Three nitinol stents were used to revascularize this artery. At 48 months, duplex-ultrasonography control revealed the presence of a 45-mm saccular femoral dilatation; X-rays and CT angiography showed fractures of the proximal stents and the presence of a pseudoaneurysm at the site of the distal stents disconnection. The pseudoaneurysm was excluded using two stent-grafts. We conclude that patients and surgeons should be aware of structural complications with all stents. Rigorous follow-up controls should be mandatory. Endovascular repair proved to be feasible and durable to manage a previous endovascular procedure.

    Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea. PMID:22880189

    Background A bleeding pseudoaneurysm in patients with chronic pancreatitis is a rare and potentially lethal complication. Optimal treatment of bleeding peripancreatic pseudoaneurysm remains controversial. This study reports on experience at Chang Gung Memorial Hospital (CGMH) in managing of bleeding pseudoaneurysms associated with chronic pancreatitis. Methods The medical records of 9 patients (8 males and 1 female; age range, 28 – 71 years; median, 36 years) with bleeding pseudoaneurysms associated with chronic pancreatitis treated at CGMH between Aug. 1992 and Sep. 2004 were retrospectively reviewed. Alcohol abuse (n = 7;78%) was the predominant predisposing factor. Diagnoses of bleeding pseudoaneurysms were based on angiographic (7/7), computed tomographic (4/7), ultrasound (2/5), and surgical (2/2) findings. Whether surgery or angiographic embolization was performed was primarily based on patient clinical condition. Median follow-up was 38 months (range, 4 – 87 months). Results Abdominal computed tomography revealed bleeding pseudoaneurysms in 4 of 7 patients (57%). Angiography determined correct diagnosis in 7 patients (7/7, 100%). The splenic artery was involved in 5 cases, the pancreaticoduodenal artery in 2, the gastroduodenal artery in 1, and the middle colic artery in 1. Initial treatment was emergency (n = 4) or elective (n = 3) surgery in 7 patients and arterial embolization in 2. Rebleeding was detected after initial treatment in 3 patients. Overall, 5 arterial embolizations and 9 surgical interventions were performed; the respective rates of success of these treatments were 20% (1/5) and 89% (8/9). Five patients developed pseudocysts before treatment (n = 3) or following intervention (n = 2). Pseudocyst formation was identified in 2 of the 3 rebleeding patients. Five patients underwent surgical treatment for associated pseudocysts and bleeding did not recur. One patient died from angiography-related complications. Overall mortality rate was 11% (1

    Objective: Penetrating carotid trauma in a hemodynamically stable patient invariably presents with a pseudoaneurysm on initial imaging. Although extremely rare, delayed pseudoaneurysm formation has been reported. The purpose of this paper is to define this rare entity and propose a diagnostic and treatment plan. Methods: We present a case of delayed presentation of carotid pseudoaneurysm following penetrating neck trauma. A systematic review of the literature was performed. Results: A 21-year-old male presents to the trauma center after sustaining a gunshot wound to the left upper back resulting in a zone 2 hematoma and pneumothorax. Bullet fragment artifact interfered with computed tomography. Carotid angiogram was normal. The patient was discharged after 3 days. He returned to the Emergency Department 3 months later with a painful pulsatile hematoma. Computed tomography angiogram revealed a 6-cm pseudoaneurysm arising from the proximal left internal carotid artery (ICA). A left common carotid artery (CCA) to ICA bypass with reversed great saphenous vein was performed. The patient’s post-operative course was uneventful, neurologic deficits improved, and he was discharged. Conclusion: Delayed presentation of traumatic pseudoaneurysms has been reported, although usually these cases are iatrogenic access complications in extremities. While endovascular therapies are first line for zone 1 and 3 vascular injuries, management of zone 2 injuries is still controversial. This patient was treated with a bypass due to the need to evacuate the hematoma that was exerting a mass effect in the neck. PMID:27489718

Conservative therapy was not effective, and phlegmonous gastritis was diagnosed based on the findings of upper gastrointestinal endoscopy and biopsy performed on the 12th day of the disease. Undernutrition and reduced physical activity were observed on hospital admission, and proactive nutritional therapy with enteral nutrition was started. An upper gastrointestinal series, performed approximately 1 month later, confirmed the persistence of strictures and impaired gastric emptying. Because conservative therapy was unlikely to improve oral food intake, open total gastrectomy was performed on the 94th day of the disease. Examination of surgically resected specimens revealed marked inflammation and fibrosis, especially in the body of the stomach. Following a good postoperative recovery, the patient was able to commence oral intake and left our hospital on foot approximately 1 month after surgery.

    Visceral aneurysms are potentially life-threatening vascular lesions. Superior mesenteric artery (SMA) pseudoaneurysms are a rare but well-recognized complication of chronic pancreatitis. Open surgical repair of such an aneurysm, especially in patients after previous surgical treatment, might be dangerous and risky. Stent graft implantation makes SMA pseudoaneurysm exclusion possible and therefore avoids a major abdominal operation. Percutaneous direct thrombin injection is also one of the methods of treating aneurysms in this area. We report a first case of percutaneous ultrasound-guided thrombin injection to complete SMA pseudoaneurysm exclusion after an unsuccessful endograft placement. Six-month follow-up did not demonstrate any signs of aneurysm recurrence.

    Abstract Background: Pseudoaneurysm of the aortic arch is uncommonly associated with cancer, and is extremely rare in pulmonary cancer. Here, we report an unusual and successfully treated case of aortic arch pseudoaneurysm in a male patient with lung squamous cell carcinoma. Methods: A 64-year-old male patient was admitted to the Emergency Department, presenting with massive hemoptysis (>500 mL blood during the 12 hours prior to treatment). The diagnosis of aortic arch pseudoaneurysm was confirmed after inspection of computed tomographic angiography and three-dimensional reconstruction. We processed the immediate endovascular stent-grafting for this patient. Results: This patient recovered with no filling or enlargement of the pseudoaneurysm, no episodes of hemoptysis, and no neurological complications during the 4-week follow-up period. Conclusion: Herein, we compare our case with other cancer-related pseudoaneurysms in the medical literature and summarize the clinical features and treatment of this unusual case. PMID:27495079

    We report a case of a 43-year-old man who developed intractable hematuria after percutaneous nephrolithotomy. Angiography detected a pseudoaneurysm arising from the lower polar artery; however, embolization could not be performed because of unfavorable vascular anatomy. A percutaneous thrombin injection under ultrasound guidance initially controlled the bleeding, but hematuria subsequently recurred as a result of recanalization of the aneurysm. The case was successfully managed with ultrasound- and fluoroscopic-guided direct injection of cyanoacrylate glue into the pseudoaneurysm.

    Traumatic pseudoaneurysm of the intracavernous internal carotid artery (ICA) is a very rare cause of epistaxis but is a life-threatening clinical situation when left untreated. The authors have experienced four cases of traumatic pseudoaneurysm involving the intracavernous ICA. Delayed massive epistaxes developed 1 to 8 months after trauma and initial transient epistaxis in all four patients. Three of the cases were successfully managed by the detachable balloon occlusion (DBO) of the ICA along with the aneurysm openings. In one case, a large pseudoaneurysm destroying a large area of the central skull base with peripheral blood clot was demonstrated on computed tomography, magnetic resonance imaging, and angiography; this patient died due to massive epistaxis before the trial of DBO. Imaging findings of pseudoaneurysms involving the intracavernous ICA in the four cases are described, and the role of endovascular treatment is discussed.

  14. Pulmonary arterial hypertension secondary to chronic left-sided cardiac dysfunction in dogs.

    PubMed

    Stepien, Rebecca L

    2009-09-01

    Pulmonary arterial hypertension is a description of a physiological finding rather than a diagnosis. Pulmonary arterial pressure is the result of interactions among pulmonary blood flow (right ventricular cardiac output), pulmonary vascular impedance and post-capillary pressure (typically reflecting left atrial pressure). When elevations in pulmonary arterial pressure (systolic/diastolic pulmonary arterial pressure > approximately 30/19 mmHg at rest) are accompanied by increased left atrial pressure, pulmonary arterial hypertension may be considered secondary to left-heart failure. Introduction of Doppler methods to diagnose pulmonary arterial hypertension has increased the awareness of the prevalence and importance of pulmonary arterial hypertension dogs with left-heart failure. Increasing understanding of the mechanism of development of pulmonary venous hypertension and reactive pulmonary arterial hypertension in dogs with left-heart disease has led to the development of successful additive therapies for progressive clinical signs in the setting of chronic therapy for congestive heart failure due to left-sided valvular and myocardial dysfunction. Because effective therapies for pulmonary arterial hypertension secondary to chronic left-sided cardiac dysfunction are now available, screening for pulmonary arterial hypertension should be a regular part of the Doppler echocardiographic examination in a clinical setting of chronic therapy for left-sided congestive heart failure due to valvular or myocardial disease.

A stress test induced no physical symptoms but revealed a left bundle branch block with multiple preventricular contractions on electrocardiogram. Subsequent catheterization revealed severe obstructive disease throughout the coronary arteries. He was treated percutaneously on two separate heart catheterizations. The presyncope and bradycardia resolved after reperfusion of the posterior descending artery. PMID:24826229

    Arterial injury during treatment of varicose veins is a rare but devastating complication that can lead to leg amputation. Approximately 6,000 patients were treated by either surgery (4,800 patients treated by ligation, stripping, and stub avulsion) or ultrasound-guided foam sclerotherapy (USGS) (1,200 patients) in the last 7 years for venous insufficiency at three medical centers. Six patients (0.1%) sustained inadvertent arterial injury. The incidence of arterial injury during surgery was 0.06% (3 of 4,800) and was of a mechanical nature amenable to repair. None of these patients had tissue loss. The injury during USGS (0.25%, 3 of 1,200) was of a chemical and irreversible nature. All three patients suffered tissue loss. In our experience, the incidence of arterial injuries during USGS is four times higher than during traditional surgery and carries a much higher risk of tissue loss. Although experience, technical skill, and awareness of this complication help reduce the incidence of arterial injury during surgery, they seem to offer no protection during USGS. Careful mapping of the arterial venous communications and avoidance of high-risk zones will help prevent this complication.

    Bow hunter's syndrome is a condition in which vertebrobasilar insufficiency is resultant from head rotation, clinically manifested by presyncopal sensation, syncope, dizziness, and nausea. It is usually diagnosed clinically, with supporting vascular imaging demonstrating an occluded or at the very least compromised unilateral vertebral artery, while the dominant vertebral artery remains patent in the neutral position. Dynamic imaging is utilized to confirm the rotational compression of the dominant vertebral artery. We present the rare case of a patient with typical Bow hunter's symptoms, bilaterally patent vertebral arteries on neutral imaging, and bilateral compromise with head rotation. Our patient underwent posterior decompression of the culprit atlanto-axial transverse foramen and subaxial cervical fusion, with resolution of his symptoms. Our patient exemplifies the possibility of bilateral dynamic vertebral artery occlusion. We show that Bow hunter's syndrome cannot be ruled out in the setting of bilaterally patent vertebral arteries on neutral imaging and that severe cervical spondylosis should impart further clinical suspicion of this unusual phenomenon.

    Arterial wall disruption, as a consequence of inflammation/infection, trauma (penetrating or blunt), or iatrogenic causes, may result in pseudoaneurysm formation. Currently, iatrogenic causes are increasing as a result of the growth of endovascular intervention. The frequency of other causes also seems to be increasing, but this may simply be the result of increased diagnosis by better imaging techniques, such as multidetector contrast-enhanced computed tomography. Clinically, pseudoaneurysms may be silent, may present with local or systemic signs, or can rupture with catastrophic consequences. Open surgical repair, previously the mainstay of treatment, has largely been replaced by image-guided occlusion methods. On the basis of an experience of over 100 pseudoaneurysms, treatments at various anatomical sites, imaging modalities used for accurate diagnosis, current changing therapeutic options for pseudoaneurysm management, approved embolization agents, and clinical follow-up requirements to ensure adequate treatment will be discussed. Image-guided direct percutaneous and endovascular embolization of pseudoaneurysms are established treatment options with favorable success rates and minimal morbidity. The pendulum has now swung from invasive surgical repair of pseudoaneurysms to that of image-guided interventional radiology.

  19. Cardiac Pseudoaneurysm- A Death Defying Entity

    PubMed Central

    2016-01-01

    A pseudoaneurysm refers to a contained rupture of the myocardium with a tenuous pericardium walling off the leak. It needs to be differentiated from a true aneurysm by the fact that there is lack of myocardial tissue in the wall of a pseudoaneurysm. The differentiation between the two is pertinent as true aneurysms can be treated medically while pseudoaneurysms require urgent surgical treatment. Untreated pseudoaneurysms carry a high risk of rupture and mortality. We report a case of cardiac pseudoaneurysm developing in a 46-year-old male who had suffered myocardial infarction four months back. The patient now presented with chest pain and dyspnoea. CECT chest revealed a partially thrombosed large pseudoaneurysm arising from the posterior wall of left ventricle. While the clinical diagnosis of this entity is difficult, CECT plays a pivotal role in the non-invasive detection of pseudoaneurysms. PMID:27504379

    We report a very rare case of a 47-year-old man who had coronary spasm that resulted in a silent myocardial infarction, a ruptured myocardial wall, and a nonruptured left ventricular pseudoaneurysm. The patient presented with a 6-month history of dyspnea on exertion, without evidence of fixed coronary artery stenosis. Coronary angiography showed severe coronary spasm of the left anterior descending and left circumflex arteries; the spasm was relieved promptly by nitroglycerin. Echocardiography and left ventricular angiography revealed the large left ventricular pseudoaneurysm posterolateral to the left ventricle. We performed surgical resection of the pseudoaneurysm and patch repair of the ruptured left ventricular wall, with excellent results. We present this case because of the highly unusual sequence of events. Early surgical intervention resulted in the patient's recovery.

    Peroneal artery arteriovenous fistulas and pseudoaneurysms are extremely rare with the majority of reported cases due to penetrating, orthopedic, or iatrogenic trauma. Failure to diagnose this unusual vascular pathology may lead to massive hemorrhage or limb threatening ischemia. We report an interesting case of a 14-year-old male who presented with acute musculoskeletal pain of his lower extremity. Initial radiographs were negative. Further imaging workup revealed a peroneal arteriovenous fistula with a large pseudoaneurysm. After initial endovascular intervention was unsuccessful, the vessels were surgically ligated in the operating room. Pathology revealed papillary endothelial hyperplasia consistent with an aneurysm and later genetic testing was consistent with Ehlers-Danlos syndrome Type IV. This case illustrates an unusual cause of acute atraumatic musculoskeletal pain and uncommon presentation of Ehlers-Danlos syndrome. PMID:25349770

    72-year-old hypertensive presented with two weeks history of left sided chest pain and hoarseness. Workup demonstrated a pseudoaneurysm in the lesser curvature of the distal aortic arch opposite the origin of the left subclavian artery from a penetrating atherosclerotic ulcer. Following a left carotid-subclavian bypass, endovascular stenting of the aorta was performed excluding the pseudoaneurysm. Patient had excellent angiographic results post-stenting. Follow up at 12 weeks demonstrated complete resolution of his symptoms and good stent position with no endo-leak. Ortner's syndrome describes vocal changes caused by cardiovascular pathology. It should be included in the differential diagnosis of patients with cardiovascular risk factors presenting with hoarseness. This case demonstrates the use of endovascular stents to treat the causative pathology with resolution of symptoms. In expert hands, it represents low risk, minimally invasive therapeutic strategy with excellent early results in patients who are high risk for open procedure. PMID:27688676

    This report presents the case of a 30-year-old motocross (BMX) cyclist with a third-degree posterior cruciate ligament rupture. The technique used for reconstruction was the transtibial single-bundle autologous hamstring technique. Unfortunately, the procedure was complicated by a popliteal pseudoaneurysm, which was located in line with the tibial canal. The pseudoaneurysm was treated with an end-to-end anastomosis and the patient recovered without further complaints. In this case, the popliteal artery was damaged most probably by the edge of the reamer or the guide wire during removal. Vascular complications can be limb- and life-threatening. This case report aims to increase the awareness of this serious complication with a review of the literature. PMID:25229050

    Vascular injuries following total hip arthroplasty (THA) are very rare, with pseudoaneurysm being a small subset. We report a case of profunda femoris artery (PFA) pseudoaneurysm in a 61-year-old male following a posterior approach revision left THA. Presentation involved continued blood transfusion requirements several weeks postoperatively. Diagnosis of the pseduoaneurysm was made by contrast CT of the lower extremity, with confirmation via IR angiography. Successful embolization was achieved with selective coiling and Gelfoam. Presenting complaints of such complications are often vague and therefore lead to delayed diagnosis. Causes of such complications are not completely understood, particularly with PFA injuries in THA. Possible mechanisms are discussed in this paper. Vascular complications following THA can be difficult to diagnose. High suspicion in the setting of continued postoperative pain or bleeding may allow prompt diagnosis and avoidance of serious limb-threatening complications. PMID:26347839

    We describe a patient with recurrent episodes of inferior ST elevation, secondary to coronary artery spasm. Each episode appeared to be provoked by the ingestion of rice and accompanied by a troponin T rise. An inpatient coronary angiogram immediately following an episode of pain demonstrated a focal area of spasm affecting the right coronary artery, which resolved with intracoronary nitrate injection. Although these episodes were self-limiting, cardiac MRI confirmed an acute subendocardial infarct. An association between food substances and coronary artery spasm with subsequent infarction has not been documented previously. Following appropriate advice and titration of antispasmodic medication, the patient has been pain free. PMID:25225191

    Secondary flow vortical patterns in arterial curvatures have the potential to affect several cardiovascular phenomena, e.g., progression of atherosclerosis by altering wall shear stresses, carotid atheromatous disease, thoracic aortic aneurysms and Marfan's syndrome. Temporal characteristics of secondary flow structures vis-à-vis physiological (pulsatile) inflow waveform were explored by continuous wavelet transform (CWT) analysis of phase-locked, two-component, two-dimensional particle image velocimeter data. Measurements were made in a 180° curved artery test section upstream of the curvature and at the 90° cross-sectional plane. Streamwise, upstream flow rate measurements were analyzed using a one-dimensional antisymmetric wavelet. Cross-stream measurements at the 90° location of the curved artery revealed interesting multi-scale, multi-strength coherent secondary flow structures. An automated process for coherent structure detection and vortical feature quantification was applied to large ensembles of PIV data. Metrics such as the number of secondary flow structures, their sizes and strengths were generated at every discrete time instance of the physiological inflow waveform. An autonomous data post-processing method incorporating two-dimensional CWT for coherent structure detection was implemented. Loss of coherence in secondary flow structures during the systolic deceleration phase is observed in accordance with previous research. The algorithmic approach presented herein further elucidated the sensitivity and dependence of morphological changes in secondary flow structures on quasiperiodicity and magnitude of temporal gradients in physiological inflow conditions.

    Large scale observational studies have conclusively demonstrated that systolic and diastolic blood pressure values are linearly related to the incidence of cerebrovascular diseases and that high blood pressure is an important risk factor for both primary and secondary development of stroke. Interventional studies have shown that blood pressure lowering by antihypertensive treatment reduces the incidence of stroke in hypertensive patients without a history of previous stroke. Whether this is the case also for the secondary prevention of cerebral ischemic attacks has not been unequivocally shown, however. The PROGRESS ("Perindopril Protection Against Recurrent Stroke Study") study has been designed and is under way to collect information on this important issue of the antihypertensive treatment, its purpose being to evaluate the blood pressure lowering effects with an ACE-inhibitor on recurrent stroke in an overall population of 6000 patients with a positive history of previous cerebral ischemic attacks or stroke.

    Embolization using N-butyl-2-cyano-acrylate (NBCA) has been highly regarded for treating pseudoaneurysm, arteriovenous malformation, and hemorrhage of the visceral arteries. We report the case of a patient who fell from a cliff and sustained hemorrhagic shock with blunt abdominal aortic rupture and who underwent embolization using NBCA. This treatment achieved immediate hemostasis and stabilization of vital signs. Although the long-term durability of NBCA is unknown, it appears that certain types of acute aortic hemorrhage with narrow-necked pseudoaneurysm can be controlled by embolization using NBCA.

    In this study, we examined the rate of change of circulation within control regions encompassing the large-scale vortical structures associated with secondary flows, i.e. deformed Dean-, Lyne- and Wall-type (D-L-W) vortices at planar cross-sections in a 180° curved artery model (curvature ratio, 1/7). Magnetic resonance velocimetry (MRV) and particle image velocimetry (PIV) experiments were performed independently, under the same physiological inflow conditions (Womersley number, 4.2) and using Newtonian blood-analog fluids. The MRV-technique performed at Stanford University produced phase-averaged, three-dimensional velocity fields. Secondary flow field comparisons of MRV-data to PIV-data at various cross-sectional planes and inflow phases were made. A wavelet-decomposition-based approach was implemented to characterize various secondary flow morphologies. We hypothesize that the persistence and decay of arterial secondary flow vortices is intrinsically related to the influence of the out-of-plane flow, tilting, in-plane convection and diffusion-related factors within the control regions. Evaluation of these factors will elucidate secondary flow structures in arterial hemodynamics.

An upper gastrointestinal endoscopy showed multiple esophageal ulcers with active arterial spurting which could not be controlled with endoscopic interventions including placement of hemostatic clips. An emergent angiogram demonstrated actively bleeding saccular dilations (pseudoaneurysms) in the esophageal branches of the lower thoracic aorta as well as left gastric artery for which gelfoam and coil embolization was initially successful. Due to recurrence of massive bleeding, she subsequently underwent emergent esophagectomy and bipolar exclusion. Pathology demonstrated submucosal hemorrhage, esophagitis with dysplastic Barrett's mucosa, and an ulcer containing cytomegaloviral inclusions. We report the first case of arterial bleeding from periesophageal pseudoaneurysms as well as use of angiographic embolization for arterial bleeding in the esophagus. PMID:27812392

    This case series examines the safety and efficacy of uterine artery embolization (UAE) in the treatment of obstructive nephropathy caused by large fibroids. Between 2004 and 2007, 10 patients referred with symptomatic uterine fibroids that were found to be causing either unilateral (7 patients) or bilateral (3 patients) hydronephrosis were treated by UAE. Presenting complaints included menorrhagia, dysmenorrhea, bulk symptoms, loin pain, postobstructive atrophy, and mild renal impairment. All had posterior intramural dominant fibroids >11 cm in maximum sagittal diameter and uterine volumes between 3776 and 15,625 ml. Outcome measures at between 12 and 36 months included procedural success, repeat intervention, relief of symptoms, resolution of hydronephrosis, stable renal function and size, and avoidance of hysterectomy. In all cases the cause of renal obstruction was confirmed to be a giant fibroid compressing the ureter at the pelvic brim. In all cases UAE was technically successful, though two patients required a repeat procedure. In eight patients hydronephrosis resolved and the obstruction was relieved, though two still had some bulk symptoms not requiring further treatment. Renal function improved or was stable in all cases. Renal size was stable in all cases. Where menorrhagia was part of the symptom complex it was relieved in all cases. Two patients diagnosed as having postobstructive atrophy of one kidney underwent retrograde ureteric stenting on the nonatrophied side prior to UAE. This was unsuccessful in one of the cases due to the distortion caused by the fibroid. Despite improvement in hydronephrosis this patient underwent hysterectomy at 7 months after a renogram demonstrated persistent obstruction at the pelvic brim. In the second patient a double pigtail stent was inserted with difficulty and eventually removed at 8 months. This patient has had stable renal function and size for 3 years post-UAE. We conclude that UAE is safe and effective in

    Summary This study was designed to elucidate the generating mechanism, diagnosis and treatment of traumatic carotid cavernous fistula (tCCF) concomitant with pseudoaneurysm in the sphenoid sinus. Six cases of tCCF concomitant with pseudoaneurysm in the sphenoid sinus were analyzed in this study. Clinical history, neurological examination, CT and MRI scans, pre- and postembolization cerebral angiograms and follow-up data were included. All patients presented with massive epistaxis and symptoms of tCCF. The pseudoaneurysms and fistulas were occluded with detachable balloons, and preservation of the parent artery in two cases. One patient also had indirect carotid cavernous fistula (CCF) on the contralateral side embolized by transfacial vein approach with microcoils. Complete symptom resolution was achieved in all cases, without procedure related complications. During the follow-up period all patients returned to work. Falling from a high speed motorcycle without wearing a helmet may be one of the main causes of this disease. The site of impact during the accident mostly localizes in the frontal and lateral of the orbit. Intracavernous sinus hypertension of tCCF combining with fracture of the lateral wall of the sphenoid may lead to the formation of a pseudoaneurysm in the sphenoid sinus. MRI scan is very helpful in the diagnosis of this disease before the patient receives angiography. Detachable balloon occlusion of the pseudoaneurysm and fistula is a safe and efficient treatment.

    Transplant renal artery stenosis (TRAS) is a potentially treatable cause of allograft dysfunction, hypertension and graft loss. The mainstay of treatment includes angioplasty and endovascular stenting, although observation and surgery are at times indicated. We present an unusual case of TRAS secondary to mechanical compression from a patient’s enlarged native polycystic kidneys. This was treated with bilateral native nephrectomy and evidence of TRAS improved both clinically and radiographically. Recognition and treatment are important in preventing irreversible complications of TRAS. PMID:23671537

Pseudoaneurysm was successfully excluded by a percutaneous approach with self-expandable stent graft deployment from the aorta to the middle of the Blalock Taussig shunt. Nearly 3 years after the procedure, the classic BT is patent, and there were no restenosis or thrombosis in spite of the very long length of the stented segment.

    Ruptured aneurysms of anterior inferior cerebellar artery (AICA) after radiotherapy for vestibular schwannoma (VS) are rare, and no definite treatment has been established for distal AICA pseudoaneurysms. We describe a 61-year-old man who underwent Gamma Knife surgery (GKS) for left VS. Follow-up magnetic resonance imaging (MRI) revealed partial regression of the tumor. Twelve years after GKS, he suffered from subarachnoid hemorrhage. Initial angiogram showed no vascular lesions; second left vertebral angiogram, 10 days after admission, demonstrated a pseudoaneurysm in the lateral pontine segment of the left AICA. The proximal portion of the AICA was occluded by a coil. Postoperative MRI revealed an infarction on the left side of the pons and brachium pontis. Although the patient suffered from mild postoperative cerebellar ataxia and facial and abducens nerve palsy, he was discharged 1 month postoperatively requiring no assistance with activities of daily living. Twelve months later, he recovered satisfactorily with a modified Rankin Scale grade of 1, and no recanalization of the aneurysm was found on MR angiography. Endovascular parent artery occlusion for ruptured aneurysms at distal AICA carries the risk of brain stem infarction, but should be considered when no other option is available such as after radiotherapy for VS.

    Background In the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), the composite primary endpoint of stroke, myocardial infarction, or death during the periprocedural period or ipsilateral stroke thereafter did not differ between carotid artery stenting and carotid endarterectomy for symptomatic or asymptomatic carotid stenosis. A secondary aim of this randomised trial was to compare the composite endpoint of restenosis or occlusion. Methods Patients with stenosis of the carotid artery who were asymptomatic or had had a transient ischaemic attack, amaurosis fugax, or a minor stroke were eligible for CREST and were enrolled at 117 clinical centres in the USA and Canada between Dec 21, 2000, and July 18, 2008. In this secondary analysis, the main endpoint was a composite of restenosis or occlusion at 2 years. Restenosis and occlusion were assessed by duplex ultrasonography at 1, 6, 12, 24, and 48 months and were defined as a reduction in diameter of the target artery of at least 70%, diagnosed by a peak systolic velocity of at least 3·0 m/s. Studies were done in CREST-certified laboratories and interpreted at the Ultrasound Core Laboratory (University of Washington). The frequency of restenosis was calculated by Kaplan-Meier survival estimates and was compared during a 2-year follow-up period. We used proportional hazards models to assess the association between baseline characteristics and risk of restenosis. Analyses were per protocol. CREST is registered with ClinicalTrials.gov, number NCT00004732. Findings 2191 patients received their assigned treatment within 30 days of randomisation and had eligible ultrasonography (1086 who had carotid artery stenting, 1105 who had carotid endarterectomy). In 2 years, 58 patients who underwent carotid artery stenting (Kaplan-Meier rate 6·0%) and 62 who had carotid endarterectomy (6·3%) had restenosis or occlusion (hazard ratio [HR] 0·90, 95% CI 0·63–1·29; p=0·58).

    2015-01-01

    A 77-year-old woman presented with a pulsatile blue-tinged mass over the left parotid, present for 5 years, and slowly enlarging. The size of the mass fluctuated during this period and there was no associated pain. The patient reported no history of surgery or trauma. Vascular lesions are rarely encountered within parotid glands in adults. MRI with contrast demonstrated a soft tissue lesion; despite the presence of feeding vessels it was thought unlikely to be an arterial venous malformation or aneurysmal change. The appearance was thought to be in keeping with an enlarged lymph node or sebaceous cyst. Fine-needle aspiration was obtained using ultrasound guidance and yielded bloody fluid. The lesion was closely related to the superficial temporal artery and a diagnosis of a thrombosed pseudoaneurysm was made. The vessel had thrombosed and the decision was made to enact a watchful waiting policy. The patient will be monitored in the outpatient setting. PMID:26311006

    Abstract Hematuria resulting from urethral traumatic catheter insertion and removal is often encountered. Usually, hematuria resolves with conservative measures. We report a case of traumatic Foley removal leading to intermittent life-threatening hematuria resulting in blood loss anemia requiring multiple transfusions and multiple episodes of hypotension requiring pressors. A pelvic angiogram revealed a pseudoaneurysm of the left pudendal artery, which was treated with microcoil embolization leading to resolution of bleeding. PMID:27579388

    The choice and optimal duration of dualantiplatelet therapy (DAPT) for the treatment of coronary artery disease (CAD) represent a challenging clinical dilemma. Antiplatelet treatment strategies are determined by the clinical setting, patient comorbidities and management strategy. While aspirin remains the cornerstone for secondary prevention of CAD, DAPT significantly reduces recurrent ischemic adverse events at the expense of an increased risk of major bleeding complications. A tailored approach based on individual ischemic and hemorrhagic risk assessment is currently recommended. This review aims to provide a contemporary overview on the current body of evidence concerning DAPT for treatment and secondary prevention of CAD with practical emphasis on current indications, choice, combination and optimal duration of antiplatelet therapy.

    Secondary flow structures arise due to curvature-related centrifugal forces and pressure imbalances. These flow structures influence wall shear stress and alter blood particle residence times. Magnetic resonance velocimetry (MRV) and particle image velocimetry (PIV) techniques were implemented independently, under the same physiological inflow conditions (Womersley number = 4.2). A 180-degree curved artery test section with curvature ratio (1/7) was used as an idealized geometry for curved arteries. Newtonian blood analog fluids were used for both MRV and PIV experiments. The MRV-technique offers the advantage of three-dimensional velocity field acquisition without requiring optical access or flow markers. Phase-averaged, two-dimensional, PIV-data at certain cross-sectional planes and inflow phases were compared to phase-averaged MRV-data to facilitate the characterization of large-scale, Dean-type vortices. Coherent structures detection methods that included a novel wavelet decomposition-based approach to characterize these flow structures was applied to both PIV- and MRV-data. The overarching goal of this study is the detection of motific, three-dimensional shapes of secondary flow structures using MRV techniques with guidance obtained from high fidelity, 2D-PIV measurements.

    Purpose. To describe our preliminary experience with a new liquid embolization agent, Onyx, in peripheral interventions. Methods and results. We successfully treated two peripheral aneurysms (one in an internal iliac artery, one in a thoracic collateral artery of an aortic coarctation), two peripheral pseudoaneurysms (one in a lumbar artery, one in a renal artery), and one pulmonary arteriovenous malformation. Conclusion. Onyx is a promising alternative embolic material for peripheral interventions. It can be combined with coils in selected cases, and balloon catheters can be effectively used during slow injection of embolic material to control flow and protect the aneurysm neck.

    Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis.

    Pseudoaneurysms of the ascending aorta are a rare complication of cardiac surgery. However, the poor prognosis associated with this condition if untreated makes early diagnosis and treatment important. We present the case of a 66-year-old woman who had undergone mitral valvuloplasty 12 days previously, who was admitted with a diagnosis of new-onset atrial fibrillation. The transthoracic echocardiogram showed a clot in the right atrium and anticoagulation was initiated, followed by antibiotic therapy. After further investigation, the patient was diagnosed with a pseudoaneurysm of the ascending aorta and underwent surgical repair, followed by six weeks of antibiotic therapy. She was readmitted six months later for an abscess of the lower sternum and mediastinum. After a conservative approach with antibiotics and local drainage failed, recurrence of a large pseudoaneurysm compressing the superior vena cava was documented. A third operation was performed to debride the infected tissue and to place an aortic allograft. There were no postoperative complications. PMID:24508151

    The interventional angiographic techniques using the percutaneous femoral approach for endovascular revascularization are becoming increasingly more popular. These methods usually require larger sheaths, and most patients need postprocedural anticoagulation or antiplatelet therapy. As a consequence, the interventional procedure is associated with a higher rate of complications at the arterial entry site compared to diagnostic angiography. The reported incidence of iatrogenic pseudoaneurysm formation after coronary artery interventions ranges from 3.2% to 7.7%, and the rates noted after diagnostic angiography range from 0.2% to 1%. Peripheral pseudoaneurysms have traditionally been treated by surgical intervention, but nonsurgical alternatives, such as ultrasound (US)-guided compression, coil embolization, stent-graft placement, and percutaneous thrombin injection with or without balloon occlusion have also been documented. Of these alternatives, direct percutaneous embolization with embolic agents is the most popular method. The tissue adhesive n-butyl cyanoacrylate (NBCA) (Hystoacryl) (B. Braun, Melsungen, Germany) is one of the most popular occluding agents for neurovascular interventions, and has been widely used for more than 20 years [5,6]. In this study, we evaluated the efficacy and utility of direct percutaneous injection of NBCA for embolization of femoral pseudoaneurysms.

    OBJECTIVE: To determine the cost-effectiveness of simvastatin in the secondary prevention of coronary artery disease (CAD) in Canada. DESIGN: Cost-effectiveness model based on results from the Scandinavian Simvastatin Survival Study (45 study) and cost and resource utilization data from Canadian sources to simulate the economic impact of long-term simvastatin treatment (15 years). PATIENTS: Subjects with mean age of 59.4 years at recruitment into 4S study. OUTCOME MEASURES: Overall death rate and incidence of 5 major nonfatal events associated with CAD: myocardial infarction, coronary artery bypass grafting, percutaneous transluminal coronary angioplasty, stroke and transient ischemic attack. Direct medical costs associated with CAD were assessed from the perspective of provincial ministries of health (i.e., costs borne by the ministries); the impact of simvastatin treatment on these costs was determined. RESULTS: The 4S study, with a median follow-up of 5.4 years, showed significantly reduced mortality and morbidity among the patients given simvastatin compared with the control subjects. Three premises were designed to predict the consequences of simvastatin treatment of CAD in Canada over 15 years, 10 years beyond the end of the 4S study. The 2 most probable premises, which assumed that the clinical benefits of simvastatin would be cumulative for either the first 10 years or the full 15 years of the model, had incremental costs per year of life gained (cost-effectiveness ratio) of $9867 and $6108 respectively. CONCLUSION: This model suggests that simvastatin provides a cost-effective approach to the long-term prevention of secondary CAD in Canada. PMID:9099167

    Behcet's disease is a complex multisystemic chronic inflammatory disease that is characterized by oral and genital aphtous ulcers and vasculitis. Aneurysms of major arteries are the most important cause of mortality in Behcet's disease. Four patients with superior mesenteric artery (SMA) aneurysms related to Behcet's disease have been reported in the literature. We report here the first successful endovascular treatment of a giant, wide-necked SMA aneurysm secondary to Behcet's disease. We performed a balloon-assisted embolization technique using ethylene vinyl alcohol copolymer (Onyx, ev3, Irvine, CA, USA). There were no signs of recurrence during 2-year follow-up.

    In general aneurysms of the pulmonary arteries are less frequent than intracranial, aortic or other vascular locations. Infectious causes include bacteria such as Staphylococcus sp and Streptococcus sp, mycobacteria, Treponema pallidium (syphilis) and rarely fungi. We report a 7 year old female with two right-sided parahilar pseudo-aneurysm of fungal origin with a prior history of ventricular septal defect. Pulmonary mycotic pseudo-aneurysms are very rare and require a high suspicion to diagnose. If a patient is still symptomatic for fever and cough for a long time, and consolidation on x-ray is not improving on antibiotics, contrast-enhanced computed tomography is indicated. It can be suspected that the "friable mass attached to ventricular septal defect patch" was a source of fungeal emboli to pulmonary arteries thus giving weight to the infective endocarditis etiology. A prior history of ventricular septal defect repair could favour fungal endocarditis. PMID:27238181

    Left ventricular (LV) pseudoaneurysm is rare in children. This report describes the case of a 2-year-old previously healthy girl who was diagnosed with endocarditis and underwent resection of a large mitral valve vegetation from the posterior mitral leaflet. One month after this surgery, she was diagnosed with a large LV pseudoaneurysm based on echocardiography performed during routine outpatient follow-up. Cardiac surgery was performed urgently to address the pseudoaneurysm, given its potential to rupture spontaneously. This case emphasizes the need for a close follow-up of children with endocarditis for development of pseudoaneurysms, which is a rare but potentially fatal complication of endocarditis.

    Ventricular free wall rupture remains the most serious complication after acute myocardial infarction. In early-recognized, subacute cases a surgical intervention using patches can be lifesaving. However, in the rare case of postoperative patch leakage, a relapse of a pseudoaneurysm may occur. This is the first case in the literature-to the best of our knowledge-describing a minimally invasive strategy using CT fluoroscopic guidance to perform an injection of thrombin into the perfused pseudoaneurysm to seal a leakage. This therapeutical regimen was chosen-in accordance with cardiac surgeons, cardiologists, and interventional radiologists-due to the high risk of adverse event after repeated surgery in this particular patient. The follow-up images showed complete occlusion of the pseudoaneurysm after the thrombin injection. This approach could be discussed in a multidisciplinary setting in similar cases, especially due to the described negligible recurrence rate after successful initial thrombosis after treating femoral pseudoaneurysms, pseudoaneurysms of the pancreatic artery, or even endoleaks after stenting of aneurysms of the aorta.

    A 17-year-old patient underwent total arch replacement for aortic arch aneurysm due to vascular Behcet's disease (BD). Follow-up computed tomography, performed 6 months after the operation, demonstrated pseudoaneurysm formation at the proximal anastomotic site. We performed endovascular treatment and used a short stent graft that was originally designed for abdominal aortic aneurysm. To avoid the occlusion of the coronary or brachiocephalic artery (BCA) due to stent graft migration, we used right ventricular rapid pacing and BCA ballooning. Thus, we believe that endovascular treatment can be used for anastomotic complications in the ascending aorta after open surgery for connective tissue disorders including BD. PMID:27174345

    High-voltage electrical burns can cause immediate and long-term neurological and cerebrovascular injuries. The authors present a 21-year-old man who developed an intracranial arteriovenous fistula secondary to high-voltage electrical injury. CT angiography demonstrated a left supraclinoid internal carotid artery (ICA)-inferior petrosal sinus (IPS) fistula. A subsequent angiogram revealed an irregularity of the cavernous and supraclinoid ICA with stenosis involving the supraclinoid segment and a fistulous connection between the ICA and IPS distal to the ophthalmic take-off and proximal to the anterior choroidal artery. The patient underwent a decompressive hemicraniectomy and clip-wrapping of his ICA pseudoaneurysm with successful obliteration of the fistulous connection. To our knowledge, this is the first report of an intracranial arteriovenous fistula secondary to an electrical burn injury.

    PurposeExplore the application of endovascular covered stent-graft (SG) placement in femoral pseudoaneurysms in intravenous drug addicts.Materials and MethodsWe evaluated a consecutive series of pseudoaneurysm in intravenous drug addicts treated with SGs from August 2010 to December 2013.Results15 patients with 16 arterial pseudoaneurysms were enrolled in this study. All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologic results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients. More evidence is required for the application of this treatment.

    A 70-year-old male with advanced pancreatic cancer went into shock after sustaining a traumatic abdominal injury. Computed tomography (CT) showed a hematoma with extravasation around the pancreas and hemorrhagic ascites. After direct catheterization failed due to angiospasm, the ruptured splenic artery was successfully occluded by transcatheter arterial embolization (TAE) using an N-butyl cyanoacrylate (NBCA)-lipiodol mixture and the patient recovered from shock without complications. A follow-up CT obtained 20 days later showed a recurrent splenic artery pseudoaneurysm without extravasation. A repeat angiogram demonstrated recanalization of the splenic artery and pseudoaneurysm via antegrade. We embolized the recanalized pseudoaneurysm using metallic coils for isolation. Our experience indicates that adequate concentration and volume of the NBCA-lipiodol mixture should be considered depending on the vascular spasm in a patient with hypovolemic shock.

  6. Synergy between shear-induced migration and secondary flows on red blood cells transport in arteries: considerations on oxygen transport

    Shear-induced migration of red blood cells (RBCs) is a well-known phenomenon characterizing blood flow in the small vessels (micrometre to millimetre size) of the cardiovascular system. In large vessels, like the abdominal aorta and the carotid artery (millimetre to centimetre size), the extent of this migration and its interaction with secondary flows has not been fully elucidated. RBC migration exerts its influence primarily on platelet concentration, oxygen transport and oxygen availability at the luminal surface, which could influence vessel wall disease processes in and adjacent to the intima. Phillips' shear-induced particle migration model, coupled to the Quemada viscosity model, was employed to simulate the macroscopic behaviour of RBCs in four patient-specific geometries: a normal abdominal aorta, an abdominal aortic aneurysm (AAA), a normal carotid bifurcation and a stenotic carotid bifurcation. Simulations show a migration of RBCs from the near-wall region with a lowering of wall haematocrit (volume fraction of RBCs) on the posterior side of the normal aorta and on the lateral-external side of the iliac arteries.

    Shear-induced migration of red blood cells (RBCs) is a well-known phenomenon characterizing blood flow in the small vessels (micrometre to millimetre size) of the cardiovascular system. In large vessels, like the abdominal aorta and the carotid artery (millimetre to centimetre size), the extent of this migration and its interaction with secondary flows has not been fully elucidated. RBC migration exerts its influence primarily on platelet concentration, oxygen transport and oxygen availability at the luminal surface, which could influence vessel wall disease processes in and adjacent to the intima. Phillips' shear-induced particle migration model, coupled to the Quemada viscosity model, was employed to simulate the macroscopic behaviour of RBCs in four patient-specific geometries: a normal abdominal aorta, an abdominal aortic aneurysm (AAA), a normal carotid bifurcation and a stenotic carotid bifurcation. Simulations show a migration of RBCs from the near-wall region with a lowering of wall haematocrit (volume fraction of RBCs) on the posterior side of the normal aorta and on the lateral-external side of the iliac arteries. A marked migration is observed on the outer wall of the carotid sinus, along the common carotid artery and in the carotid stenosis. No significant migration is observed in the AAA. The spatial and temporal patterns of wall haematocrit are correlated with the near-wall shear layer and with the secondary flows induced by the vessel curvature.

    Although endovascular intervention is the first-line treatment of intracranial aneurysm, intraprocedural rupture or extravasation is still an endangering event. We describe two interesting cases of extravasation during embolotherapy for ruptured peripheral cerebral pseudoaneurysms. Two male patients were admitted after development of sudden headache with presentation of intracerebral and subarachnoid hemorrhage, respectively. Initial angiographic assessment failed to uncover any aneurysmal dilatation in both patients. Two weeks afterwards, catheter angiography revealed aneurysms each in the peripheral middle cerebral artery and anterior inferior cerebellar artery. Under a general anesthesia, endovascular embolization was attempted without systemic heparinization. In each case, sudden extravasation was noted around the aneurysm during manual injection of contrast after microcatheter navigation. Immediate computed tomographic scan showed a large amount of contrast collection within the brain, but they tolerated and made an unremarkable recovery thereafter. Intraprocedural extravasation is an endangering event and needs prompt management, however proximal plugging with coil deployment can be sufficient alternative, if one confronts with peripheral pseudoaneurysm. Peculiar angiographic features are deemed attributable to extremely fragile, porous vascular wall of the pseudoaneurysm. Accordingly, it should be noted that extreme caution being needed to handle such a friable vascular lesion. PMID:19096673

    Purpose: To evaluate the suitability of transbrachial access for endovascular renal artery interventions. Methods: During 37 consecutive endovascular renal artery interventions, the transbrachial approach was used on nine patients (mean age 63 years; range 41-76 years) for 11 renal artery procedures on native kidneys and one percutaneous transluminal angioplasty (PTA) on a transplanted kidney. The reason for using transbrachial access was a steep aorta-renal angle in five, and severe aorta-iliac atherosclerosis in the remaining patients. In addition to the intervention catheter in the left brachial artery, an additional nonselective catheter for controlling the procedure was inserted transfemorally (six patients) or via the contralateral brachial artery. Results: Eleven interventions (six PTAs, five stents) were successfully completed. The one failure resulted from impenetrable subclavian artery stenosis. The only major complication was a brachial artery pseudoaneurysm requiring surgical treatment. Conclusion: Transbrachial access is an effective and relatively safe technique for renal artery interventions when transfemoral access is not possible.

    A thoracic aortic pseudoaneurysm is a life-threatening complication following thoracic aortic surgery. We describe a surgical strategy for this pseudoaneurysm with a high risk for rupture during median sternotomy. The pseudoaneurysm was distended and widely adherent to the posterior sternum. Elective cardiopulmonary bypass and moderate hypothermia were established, and sternotomy was performed without left ventricle distention or brain ischemia. Total arch replacement was successful and the patient was discharged on post operative day (POD) 18. A key surgical strategy was to avoid ventricular fibrillation before sternotomy. Appropriate sternotomy timing and perfusion strategy are crucial for successful treatment.

    There are some reports of renal vein thrombosis associated with acute pyelonephritis, but a case of renal artery thrombosis in acute pyelonephritis has not been reported yet. Here we report a case of renal artery thrombosis which developed in a patient with acute pyelonephritis complicated with sepsis-induced disseminated intravascular coagulation (DIC). A 65-year-old woman with diabetes was diagnosed with acute pyelonephritis complicated with sepsis. Escherichia coli was isolated from both blood and urine cultures. When treated with antibiotics, her condition gradually improved. She suddenly complained of severe right flank pain without fever in the recovery phase. A computed tomography scan revealed right renal artery thrombosis with concomitant renal infarction. Prophylactic anticoagulation therapy was not suggested because of sustained thrombocytopenia and increased risk of bleeding. Flank pain resolved with conservative treatment and perfusion of infarcted kidney improved at the time of discharge. To our knowledge, this is the first case of renal artery thrombosis related to acute pyelonephritis with sepsis-induced DIC. PMID:26889428

    Splenic vein thrombosis can lead to gastric varices. Subsequent upper gastrointestinal bleeding may ensue related to the change in venous outflow to the portal system. Vascular surgeons are infrequently asked to assist in the management of this entity. However, with many vascular surgeons providing diverse endovascular-based interventions, understanding catheter-based solutions is imperative. This report presents a case in which arterial embolization was used to treat gastric variceal bleeding.

    Introduction Splenic pseudoaneurysms (SPA) are a rare but serious sequela of blunt traumatic injury to the spleen. Management of adult blunt splenic trauma is well-studied, however, in children, the management is much less well-defined. Presentation of case A 15 year-old male presented with severe abdominal pain of acute onset after sustaining injury to his left side while playing football. FAST was positive for free fluid in the abdomen. Initial abdomen CT demonstrated a grade III/IV left splenic laceration with moderate to large hemoperitoneum with no active extravasation or injury to the splenic vessels noted. A follow-up CT angiography of the abdomen demonstrated a splenic hypervascular structure suspicious for a small pseudoaneurysm. Splenic arteriogram which demonstrated multiple pseudoaneurysms arising from the second order splenic artery branches which was angioembolized and treated. Discussion & conclusion Questions still remain regarding the timing of repeat imaging for diagnosis of SPA following non-operative blunt splenic trauma, which patients should be imaged, and how to manage SPA upon diagnosis. More clinical study and basic science research is warranted to study the disease process of SPA in pediatric patient. We believe that our proposed management algorithm timely detect formation of delayed SPA formation and addresses the possible fatal disease course of pediatric SPA. PMID:26117449

    We report a rare case of a tuberculous mycotic aortoiliac pseudoaneurysm treated with an endovascular procedure and follow-up of 36 months. The patient was a white 72-year-old man with pulmonary tuberculosis and a former smoker with hypertension, chronic renal failure, and dyslipidemia. A computed tomographic scan of the abdomen and pelvis revealed a left paravertebral cavity with fluid content and involvement of vertebrae L2-L4. After a surgical repair attempt, the patient was treated with the implant of a bifurcated endoprosthesis. Because it is unlikely that any center has extensive experience in the management of this rare manifestation of the disease, we reviewed the literature for similar cases.

    A 59-year-old woman consulted our hospital for a left renal mass which she had been aware of for 4 years. The tumor was in the lower portion of the left kidney. It was a cystic tumor whose wall was enhanced on computed tomography and magnetic resonance imaging. The lesion 3.0 cm in diameter, which was enhanced equally to the aorta, was found in a part of the wall. It was thought to be a pseudoaneurysm by renal angiography. We suspected a cystic renal cell carcinoma because of the plural feeding arteries and tumor staining, and performed left total nephrectomy. Pathological diagnosis was angiomyolipoma with few fat components. To our knowledge only 3 previous cases of renal angiomyolipoma with marked cystic degeneration have been reported in Japan. In all 3 cases, it was difficult in preoperative diagnosis to distinguish angiomyolipoma with cystic degeneration from cystic renal cell carcinoma complicated cyst. Moreover, this is the first reported case of renal angiomyolipoma with marked cystic degeneration and pseudoaneurysm.

    Enlarging aneurysms in the thoracic aorta frequently remain asymptomatic. Fistulization of thoracic aortic aneurysms (TAA) to adjacent structures or the presence of a patent ductus arteriosus and TAA may lead to irreversible cardiopulmonary sequelae. This article reports on a large aneurysm of the thoracic aorta with communication to the pulmonary artery causing pulmonary edema and cardiorespiratory failure. The communication was ultimately closed after thoracic endovascular aortic aneurysm repair allowing rapid symptom resolution. Early diagnosis and closure of such communication in the presence of TAA are critical for prevention of permanent cardiopulmonary damage.

    Advances in palliation of congenital heart disease have resulted in improved survival to adulthood. Many of these patients ultimately develop end-stage heart failure requiring left ventricular assist device implantation (LVAD). However, morphologic differences in the systemic ventricle of these patients require careful attention to cannula placement. We report on the evolution of our surgical technique for implanting LVADs in 3 patients with transposition of the great arteries and congenitally corrected transposition of the great arteries. Applying standard LV cannulation techniques to the systemic ventricle led us too anteriorly in our first patient, creating obstruction by the moderator band. Subsequent use of epicardial and transesophageal echocardiography allowed for intraoperative localization of the intracardiac muscular structures to identify the optimal cannulation site. The acute angle of the inflow cannula on the DeBakey LVAD (MicroMed Technology, Houston, TX) required flipping the device 180°. The HeartMate II device (Thoratec, Pleasanton, CA) could be shifted towards the midline. One patient underwent successful transplant and 2 are home waiting for a donor organ. We conclude from our experience that LVAD surgery can be safely performed in patients with congenital heart disease when implanted under echocardiographic guidance. PMID:20620085

    Aneurysm of the cystic artery is not common, and it is a rare cause of hemobilia. Most of reported cases are pseudoaneurysms resulting from either an inflammatory process in the abdomen or abdominal trauma. We report a healthy individual who developed hemobilia associated with cystic artery aneurysm. The patient was managed with cholecystectomy and concomitant aneurysm repair. Visceral artery aneurysms are rare and can rupture with potentially grave outcome due to excessive bleeding. Angiographic embolization is a common method of treatment for visceral artery aneurysms. Open cholecystectomy and aneurysm repair was performed in our patient due to radiological evidence of associated cholecystitis.

    An in vitro experimental investigation of secondary flow structures was performed downstream of a model stent that embodied a ``Type-IV'' stent fracture, i.e. complete transverse fracture of elements and element displacement (of 3 diameters). One part of the fractured stent was located in the curved region of a test section comprised of a 180-degree bent tube, and the velocity field measured with PIV. Secondary flow morphologies downstream of the stent were identified with a continuous wavelet transform (CWT) algorithm (PIVlet 1.2) using a 2D Ricker wavelet. A comparison of wavelet transformed vorticity fields of fractured and unfractured model stents is presented under physiological inflow conditions. During systolic deceleration, a breakdown in symmetry of vortical structures occurred with the unfractured stent, but not with the fractured model stent. Potential mechanisms to explain the differences in secondary flow morphologies include redirection of vorticity from the meridional plane of the bend to the normal plane and diffusion of vorticity.

    The purpose of this paper is to report our experience with the endovascular treatment of crural arterial injuries using transcatheter and direct embolization techniques. A total of eight consecutive patients have been treated during a 7-year period. Six males and two females, mean age 32 years (range, 15-56 years), presented with penetrating trauma to the lower extremities. Mechanisms of injuries were stab wounds in six patients, gun shot wound in one patient, and iatrogenic injury in one patient. Five patients presented with acute trauma, while three patients presented with delayed injuries. Crural arterial injuries encountered included pseudoaneurysms with arteriovenous fistulas (n = 6), pseudoaneurysms with vessel transections (n = 2), and pseudoaneurysm (n = 1). Proximal and distal embolization with coils was used in three cases, proximal embolization with coils in three cases, percutaneous thrombin injection in one case, and liquid n-butyl cyanoacrylate in one case. Complete exclusion of the lesions was accomplished by sacrifice of one crural vessel in seven cases and of two crural vessels in one case. Two cases of delayed injuries required combined coil and liquid embolization techniques for lesion exclusion. A minor complication (groin hematoma) occurred in one patient, no distal ischemia was seen, and no amputations were required. Mean follow-up was 61 days (range, 1-180 days). One pseudoaneurysm treated with thrombin injection recurred and required surgical excision. We conclude that transcatheter embolization alone or in combination with different endovascular techniques is useful in the treatment of traumatic crural vessel injuries.

    The arterial network in the human vasculature comprises of ubiquitously present blood vessels with complex geometries (branches, curvatures and tortuosity). Secondary flow structures are vortical flow patterns that occur in curved arteries due to the combined action of centrifugal forces, adverse pressure gradients and inflow characteristics. Such flow morphologies are greatly affected by pulsatility and multiple harmonics of physiological inflow conditions and vary greatly in size-strength-shape characteristics compared to non-physiological (steady and oscillatory) flows (1 - 7). Secondary flow structures may ultimately influence the wall shear stress and exposure time of blood-borne particles toward progression of atherosclerosis, restenosis, sensitization of platelets and thrombosis (4 - 6, 8 - 13). Therefore, the ability to detect and characterize these structures under laboratory-controlled conditions is precursor to further clinical investigations. A common surgical treatment to atherosclerosis is stent implantation, to open up stenosed arteries for unobstructed blood flow. But the concomitant flow perturbations due to stent installations result in multi-scale secondary flow morphologies (4 - 6). Progressively higher order complexities such as asymmetry and loss in coherence can be induced by ensuing stent failures vis-à-vis those under unperturbed flows (5). These stent failures have been classified as "Types I-to-IV" based on failure considerations and clinical severity (14). This study presents a protocol for the experimental investigation of the complex secondary flow structures due to complete transverse stent fracture and linear displacement of fractured parts ("Type IV") in a curved artery model. The experimental method involves the implementation of particle image velocimetry (2C-2D PIV) techniques with an archetypal carotid artery inflow waveform, a refractive index matched blood-analog working fluid for phase-averaged measurements (15 - 18

    Inward centrifuging of fluid in the inviscid core of a 180 degree curved pipe leads to Lyne-type vortices under zero-mean harmonic oscillations, along with the formation of vortices in the Stokes' layer, that rotate in the same directional sense as their steady flow counterpart (Dean vortices). Under physiological conditions, the development of the Lyne-type vortices is believed to be influenced by the systolic pulse, and its associated rapid acceleration and deceleration. Experimental data acquired using Particle Image Velocimetry (PIV) for three harmonic waveforms of different frequencies clarify the conditions under which Lyne vortices form. Multiple vortex pairs were observed for all waveforms and frequencies investigated, including Dean and Lyne-type vortex structures at a Womersley number of 4.22, much lower than previously reported. Hence, frequency alone is not an adequate governing parameter to characterize secondary flow structures in pulsatile flows. A regime map of the secondary flow was sought by using an acceleration-based parameter and the Dean number.

    Pseudoaneurysm is an uncommon sequela of infective endocarditis. We treated a 44-year-old man who had an active case of group B streptococcal infective endocarditis of the aortic valve despite no evidence of valvular dysfunction or vegetation on his initial transesophageal echocardiogram. After completing 6 weeks of intravenous antibiotic therapy, the patient developed a sinus of Valsalva pseudoaneurysm and severe aortic regurgitation caused by partial detachment of the left coronary cusp. We used a pericardial patch to close the pseudoaneurysm and repair the coronary cusp. This case shows the importance of routine clinical follow-up evaluation in infective endocarditis, even after completion of antibiotic therapy. Late sequelae associated with infective endocarditis or its therapy include recurrent infection, heart failure caused by valvular dysfunction (albeit delayed), and antibiotic toxicity such as aminoglycoside-induced nephropathy and vestibular toxicity.

    There are very few data regarding the effects of norepinephrine uptitration on global and regional hemodynamics in cardiogenic shock. We studied 25 patients with shock secondary to myocardial infarction successfully treated with percutaneous coronary intervention. Before the inclusion, 16 of 25 patients presented a cardiac arrest in the presence of medical staff. Norepinephrine was titrated to increase mean arterial pressure (MAP) from 65 to 85 mmHg during 1 h. Swan-Ganz variables, arterial and mixed venous blood gases, lactate, and thenar near-infrared spectroscopy variables (muscle tissue oxygen saturation [StO2] and its changes during a vascular occlusion test) were measured before, 1 h after norepinephrine uptitration, and 1 h after norepinephrine downtitration. To obtain a MAP at 85 mmHg, norepinephrine was increased from 0.6 (0.28-1.2) to 1.53 µg · kg · min (0.76-2.6 µg · kg · min) (P < 0.00001) (median and interquartile range), with no change in heart rate. Norepinephrine uptitration significantly increased cardiac index (2.3 ± 0.5 to 2.8 ± 0.1 L · min · m), cardiac power index (0.40 ± 0.1 to 0.55 ± 0.1 W/m), mixed venous oxygen saturation (69% ± 9% to 73% ± 9%), and coronary perfusion pressure (32 ± 3 to 43 ± 4 mmHg). Lactate level decreased from 2.6 ± 1.7 to 1.6 ± 0.4 mmol/L (P < 0.05). Pulmonary artery occlusion pressure remained unchanged. Regarding near-infrared spectroscopy variables, all values except StO2 were significantly pathological when compared with healthy volunteers. The StO2 recovery slope and delta StO2, respectively, increased from 3.0% ± 1.3%/s to 3.6% ± 1.3%/s and 10% ± 3% to 14% ± 4%, whereas StO2 did not change (83% ± 6% to 83% ± 7%). After H1, norepinephrine was decreased to basal values, and all variables returned to baseline. In conclusion, a short-term increase in MAP with norepinephrine in resuscitated cardiogenic shock complicated by postreperfusion disease is associated with better cardiac performance and

    Although exact definitions of exercise requirements for primary and secondary prevention of coronary disease cannot be stated with certainty on the basis of currently available information, we can make some general conclusions. The characteristics associated with lowered risk from coronary disease in apparently normal populations are: 8 MET-hours of activity during leisure time or job: walking briskly during leisure time (1 hour = 1 MET-hour) walking at job (same as above) jogging during leisure time (30 minutes of activity = 1 MET-hour) walking to and from work (same as walking above) performing very heavy work in occupational pursuits (few jobs today have those energy requirements) regularly climbing 5 flights or more of stairs (10 steps per flight) regularly walking 5 city blocks per day (12 blocks per mile) regularly engaging in strenuous sports (basketball, running, mountaineering, skiing, swimming, or tennis) accumulating activities that use 2000 or more kcal per week Conclusions concerning the prevention of reinfarction in patients who are recovering from a first heart attack include: Exercise is helpful in hastening the recovery process after myocardial infarction and should be started early in the recovery period. Exercise helps to reduce mortality when used in conjunction with a multifactorial program.

    The purpose of this study is to investigate the development of vortical flow structures of blood like fluids in a 180 degree tube bend, analogous to the aortic arch. Cardiovascular diseases are localized to regions of curvature in the arterial tree. The pathology of atherogenesis is widely considered an inflammatory response, hypothesized to be modulated by the interplay between Wall Shear Stress (WSS) variations and particulate transport mechanisms from the bulk fluid core to the near wall. The WSS is determined by the local flow characteristics as well as the rheological properties of the blood, which in turn are dependent on the bulk secondary flows. In this work, the time dependent fluid flow under various physiological flow conditions are investigated both experimentally and numerically. A Newtonian blood analog fluid model is considered in both studies to validate both methods and thereby study flow structure development during steady as well as pulsatile conditions. Particle image velocimetry (2C - 2D PIV) is used to acquire velocity field data from an acrylic tube bend. The numerical study is extended to consider the non-Newtonian properties of blood according to an empirical model to identify the relative importance of the non-Newtonian behavior. The studies show complex Dean and Lyne vortex interaction that are enhanced with increasing peak Reynolds numbers.

  16. Management of nonocclusive hepatic artery complications after liver transplantation.

    Nonocclusive arterial disease represents less than 5% of posttransplant arterial complications. Nonocclusive arterial complications are classified into (1) nonocclusive diminished flow in the hepatic artery, (2) arteriovenous fistulae, (3) pseudoaneurysms, and (4) arterial rupture. Due to the rarity of these complications, particularly when considering them individually, many of the opinions and managements of these complications are anecdotal. Transcatheter embolization is the main mode of minimal invasive management of these uncommon complications. Other minimal invasive methods have been described such as stent placement or direct percutaneous embolization/thrombosis. The article discusses the presentation, etiology, types, treatment indications, and various modes of minimal invasive therapy used to manage these complications.

    Pseudoaneurysms of the inferior gluteal artery (IGA) are rare and are often caused by trauma. Treatment options vary and include surgery, ultrasound-guided percutaneous thrombin injection, and endovascular procedures such as stent-graft placement, coil embolization, and glue injection. We report a 70-year-old male who presented to the hospital after a road accident with a posttraumatic pseudoaneurysm that was treated by endovascular thrombin embolization. To the best of our knowledge, this is the first reported case of inferior gluteal artery false aneurysm treated by this method.

    Local cold exposure tests are used to diagnose cold-induced vasospastic disorders and to evaluate therapeutic success. We investigated the pulsatile signal detected with a newly developed arterial photoplethysmography (APPG) method and the signal change induced by local cold exposure using a temperature-controlled finger holder, comparing it with laser Doppler flux (red and green laser, rLDF and gLDF) and red blood cell velocity measured in nailfold capillaries (CBV). Ten healthy volunteers and 10 age- and sex-matched patients suffering from Raynaud's phenomenon due to systemic sclerosis were investigated using a moderate cooling temperature of 16 degrees C for 5 min. All signals were recorded simultaneously. The results show a significant reduction of CBV (P < 0.0001), rLDF (P < 0.0003), and gLDF (P = 0.0214) during cooling and characteristic changes in the APPG signal (for instance a decrease in pulse wave amplitude; P < 0.0001). Significant differences in the APPG amplitude could be detected under resting conditions; at cooling temperatures there were also significant differences in CBV and APPG. The temperature-controlled finger holder with its built-in APPG probe appears to be a useful tool for evaluating the effect of local cooling on finger skin perfusion and differentiating between healthy controls and patients with secondary Raynaud's phenomenon due to systemic sclerosis. The gLDF signal was rather weak, limiting its value in cold stress tests. The differences between controls and patients in CBV were somewhat smaller than in previous studies, suggesting the advantage of lower local cooling temperatures, e.g., 12 degrees C.

    Indium-111 (In-111) leukocyte scintigraphy was performed in two patients with postsurgical pseudoaneurysms as part of preoperative evaluation for evidence of graft infection. Despite positive In-111 uptake by the pseudoaneurysms, surgical and pathologic examinations failed to reveal any evidence of infection. The most likely explanation for the false-positive results is the labeling of contaminating platelets and erythrocytes in the leukocyte mixture. Caution must be exercised in interpretation of In-111 leukocyte scans in patients with postsurgical pseudoaneurysms.

    A common treatment for atherosclerosis is the opening of narrowed arteries resulting from obstructive lesions by angioplasty and stent implantation to restore unrestricted blood flow. ``Type-IV'' stent fractures involve complete transverse, linear fracture of stent struts, along with displacement of the stent fragments. Experimental data pertaining to secondary flows in the presence of stents that underwent ``Type-IV'' fractures in a bent artery model under physiological inflow conditions were obtained through a two-component, two-dimensional (2C-2D) PIV technique. Concomitant stent-induced flow perturbations result in secondary flow structures with complex, multi-scale morphologies and varying size-strength characteristics. Ultimately, these flow structures may have a role to play in restenosis and progression of atherosclerotic plaque. Vortex circulation thresholds were established with the goal of resolving and tracking iso-circulation secondary flow vortical structures and their morphological changes. This allowed for a parametric evaluation and quantitative representation of secondary flow structures undergoing deformation and spatial reorganization.

    Secondary flow structures are known to affect wall shear stress, which is closely related to atherogenesis and drug particle deposition. A regime map provides a framework to examine phase-wise variations in secondary flow structures under physiological and multi-harmonic inflow waveforms under conditions of a fixed Womersley number (4.2) and curvature ratio (1/7). Experimental PIV data were acquired at the 90-degree location in a 180-degree curved test section of a bent tube model for curved arteries using a blood analog working fluid. Coherent structure detection was performed using a continuous wavelet transform algorithm (PIVlet 1.2) and further analysis was carried out by grouping similar secondary flow structures at a fixed secondary Reynolds numbers. Phase-locked, planar vorticity fields over one period of inflow waveform revealed size, structure and strength similarities in secondary flow morphologies during the acceleration and deceleration phases. The utility of the new regime map lies in the a priori identification of pulsatile secondary flow structures, eliminating the need for exhaustive experimentation or computing, requiring only flow rate measurements that are easily acquired under clinical conditions.

    A 60 year-old woman, who had a 45-year history of systemic lupus erythematosus (SLE) and secondary antiphospholipid syndrome, presented with subarachnoid hemorrhage due to a ruptured aneurysm at the anterior wall of the non-branching site of the right internal carotid artery. She underwent radical surgery on the day of onset. In light of the possibility of arterial dissection, we performed extracranial-intracranial bypass prior to careful exploration of the aneurysm. Based on the finding of saccular aneurysm, she ultimately underwent neck clipping of the aneurysm without complication. Postoperative course was uneventful, and she did not suffer from cerebral vasospasm. We recommend early surgical intervention in patients with aneurysmal SAH associated with SLE, while intrinsic pathologies of SLE such as fragile vascular structure and the risk for ischemic complication should be considered.

    Abstract The aims of this study were to identify arteriographic manifestations of acute renal hemorrhage and to evaluate the efficacy of emergency embolization. Emergency renal artery angiography was performed on 83 patients with acute renal hemorrhage. As soon as bleeding arteries were identified, emergency embolization was performed using gelatin sponge, polyvinyl alcohol particles, and coils. The arteriographic presentation and the effect of the treatment for acute renal hemorrhage were analyzed retrospectively. Contrast extravasation was observed in 41 patients. Renal arteriovenous fistulas were found in 12 of the 41 patients. In all, 8 other patients had a renal pseudoaneurysm, 5 had pseudoaneurysm rupture complicated by a renal arteriovenous fistula, and 1 had pseudoaneurysm rupture complicated by a renal artery-calyceal fistula. Another 16 patients had tumor vasculature seen on arteriography. Before the procedure, 35 patients underwent renal artery computed tomography angiography (CTA). Following emergency embolization, complete hemostasis was achieved in 80 patients, although persistent hematuria was present in 3 renal trauma patients and 1 patient who had undergone percutaneous nephrolithotomy (justifying surgical removal of the ipsilateral kidney in this patient). Two-year follow-up revealed an overall effective rate of 95.18 % (79/83) for emergency embolization. There were no serious complications. Emergency embolization is a safe, effective, minimally invasive treatment for renal hemorrhage. Because of the diversified arteriographic presentation of acute renal hemorrhage, proper selection of the embolic agent is a key to successful hemostasis. Preoperative renal CTA plays an important role in diagnosing and localizing the bleeding artery. PMID:26496273

    Interpretation of complex flow patterns observed in this study of a model curved artery required characterization of multiple, low-circulation secondary flow structures that were observed during the late systolic deceleration and diastolic phases under physiological inflow conditions. Phase-locked, planar vorticity PIV data were acquired at various cross-sectional locations of the 180-degree bent tube model. High circulation, deformed Dean- and Lyne-type vortices were observed during early stages of deceleration, while several smaller scale, highly deformed, low-circulation vortical patterns appeared in the core and near-wall regions during late systolic deceleration and diastolic phases. Due to the multiplicity of vortical scales and shapes, anisotropic 2D Ricker wavelets were used for coherent structure detection in a continuous wavelet transform algorithm (PIVlet 1.2). Our bio-inspired study is geared towards understanding whether optimizing the shape of the wavelet kernel will enable better resolution of several low-circulation, multi-scale secondary flow morphologies and whether new insights into the dynamics of arterial secondary flow structures can accordingly be gained.

    Radial artery puncture, an invasive procedure, is frequently used for critical patients. Although considered safe, severe complications such as finger necrosis can occur. Herein, we review the clinical course of finger necrosis after accidental radial artery puncture. A 63-year-old woman visited the emergency department (ED) with left second and third finger pain after undergoing intravenous (IV) access in her wrist for procedural sedation. During the IV access, she experienced wrist pain, which increased during the 12 hours prior to her ED presentation. Emergency angiography revealed a pseudoaneurysm in her left radial artery and absence of blood flow to the proper palmar digital artery. Subsequent angiointervention and urokinase thrombolysis failed. The second finger was eventually amputated owing to gangrene. Radial artery puncture can occur accidentally during IV wrist access, resulting in severe morbidity. Providers should carefully examine the puncture site and collateral flow, followed by multiple examinations to ensure distal circulation.

    Hepatic artery complications after liver transplantation are uncommon, but represent an important cause of morbidity and mortality. In addition, these complications tax an already limited supply of donor organs because of the frequent need for retransplantation in this group of patients. In this study, we examined the incidence of hepatic arterial anomalies in donors and recipients of orthotopic liver transplants, focusing on the techniques that are available for hepatic arterial reconstruction and on the occurrence of hepatic arterial complications. A total of 77 liver transplants were carried out in 68 patients. Standard recipient anatomy was present in 60 of 68 patients (88%). Anomalous vessels were identified in eight patients (12%), including six cases of replaced right hepatic artery (9%) and two cases of replaced left hepatic artery (3%). Donor liver arterial anatomy was standard in 62 cases (80%). Anomalous arterial supply was identified in 15 of 77 donor livers (20%), including replaced left hepatic artery in nine (12%) and replaced right hepatic artery in six (8%). A variety of methods were used to manage the anomalous vessels. There was one hepatic artery pseudoaneurysm, three cases of hepatic artery thrombosis (4%), and one patient developed a dissection of the native celiac axis. In primary transplants, utilization of the recipient's proper hepatic artery was associated with a significantly higher risk of hepatic artery thrombosis (P less than 0.04) when compared with the common hepatic artery or the branch patch technique. Use of a Carrel patch on the donor artery was associated with a significantly reduced incidence of hepatic artery thrombosis (P less than 0.0003). For retransplantation, it is recommended that a more proximal recipient anastomotic site be chosen. An innovative method is described that provides increased length of the donor arterial supply without the use of an arterial graft. PMID:2675403

    Purpose: To evaluate the feasibility and short-term follow-up results of treating iliac aneurysms by the Cragg Endopro System 1 stent-graft. Methods: Nine lesions (two pseudoaneurysms and seven atherosclerotic aneurysms) were treated in eight patients by percutaneous implantation of a total of 10 stent-grafts. The procedure was followed by anticoagulation with heparin for 6 days, then antiplatelet therapy. Follow-up was by color Doppler ultrasound scan at 2 days and 3 months after the procedure for all patients, and by venous digital subtraction angiography and/or angio-CT up to 12 months later for four patients. Results: Initial clinical success rate was 100% and there were two minor complications. In one case the delivery system was faulty resulting in failure to deploy the stent-graft. An additional device had to be used. At 3-12 months all prostheses were patent but one patient (12.5%) had a minimal pergraft leak. Conclusion: Percutaneous stent-grafting with this device is a safe and efficacious treatment of iliac artery aneurysms.

Computed tomography of the chest at the time of admission showed dissection of the aortic arch, descending aorta and dissection of an aberrant right subclavian artery. She was managed medically for Stanford type B acute aortic dissection. The patient was asymptomatic at presentation, but started complaining of new-onset dysphagia during her stay in the hospital. An esophagogram was performed and suggested posterior impingement of the esophagus, a classic sign of an aberrant right subclavian artery. Because the patient had multiple underlying comorbidities and the dysphagia was mild and intermittent, surgery was deferred. The patient was discharged home after complete stabilization and was scheduled for a follow-up appointment. PMID:18209773

We report two rare cases of aortoesophageal fistula and aortic pseudoaneurysm caused by esophagus perforation after accidental swallow of fish bone; the patients also had purulent mediastinitis and esophagitis. The treatment of aortic pseudoaneurysm was successful in both cases, with one patient undergoing surgical resection and aortic neoplasty and the other patient undergoing endovascular stent graft placement. Long-term antibiotic treatment was administered to both patients after surgery. There were no postsurgical complications, and the patients recovered without incident.

    2016-01-01

    Purpose: The goal of this study was to evaluate the effect of vascular compliance, resistance, and pulse rate on the resistive index (RI) by using an electrical circuit model to simulate renal blood flow. Methods: In order to analyze the renal arterial Doppler waveform, we modeled the renal blood-flow circuit with an equivalent simple electrical circuit containing resistance, inductance, and capacitance. The relationships among the impedance, resistance, and compliance of the circuit were derived from well-known equations, including Kirchhoff’s current law for alternating current circuits. Simulated velocity-time profiles for pulsatile flow were generated using Mathematica (Wolfram Research) and the influence of resistance, compliance, and pulse rate on waveforms and the RI was evaluated. Results: Resistance and compliance were found to alter the waveforms independently. The impedance of the circuit increased with increasing proximal compliance, proximal resistance, and distal resistance. The impedance decreased with increasing distal compliance. The RI of the circuit decreased with increasing proximal compliance and resistance. The RI increased with increasing distal compliance and resistance. No positive correlation between impedance and the RI was found. Pulse rate was found to be an extrinsic factor that also influenced the RI. Conclusion: This simulation study using an electrical circuit model led to a better understanding of the renal arterial Doppler waveform and the RI, which may be useful for interpreting Doppler findings in various clinical settings.

    ABSTRACT Statin and antiplatelet drugs are widely used for prevention of ischaemic stroke and other cardiovascular diseases in high-risk patients. We report a rare case of a 49-year old man with a history of myocardial infarction and hyperlipidaemia who suffered an acute occlusion of his innominate artery (IA) accompanied by subclavian steal syndrome and cerebral infarction, on day seven after abrupt cessation of aspirin and statin, as confirmed by magnetic resonance and computed tomographic angiography of head and neck, and colour-coded Duplex ultrasonography (CCDU). Aspirin and atorvastatin were immediately re-started on admission. Spontaneous recanalization of IA was shown on repeat CCDU and digital subtraction angiography on day 10 after stroke onset. This case serves as a reminder that abrupt discontinuation of both aspirin and statin in patients with previous history of cardiovascular disease may increase the risk of ischaemic stroke.

    The development of a pseudoaneurysm is a rare complication following repair of a coarctation of the aorta. Surgical management of pseudoaneurysms is associated with high morbidity and mortality. We describe the successful endovascular deployment of a covered stent in a sick infant with a descending aorta pseudoaneurysm, following the repair of an aortic coarctation. We highlight the challenges we encountered. Endovascular repair is a safe palliative alternative to re-do open surgery in unstable infants with large pseudoaneurysms following aortic coarctation repair. The role of endovascular stents as the final definitive therapy will remain limited by the deployable, small-size stents in small, growing children.

    A 36-year-old man, who had undergone thoracoscopic anterior spinal fusion using the plate system and posterior screw fusion three months previously, presented to our hospital with left flank pain and fever. Computed tomography indicated the presence of a psoas muscle abscess. However, after two days of percutaneous catheter drainage, a mycotic abdominal aortic pseudoaneurysm was detected via computed tomography. We performed in situ revascularization using a prosthetic graft with omental wrapping. Methicillin-resistant Staphylococcus aureus was identified on blood and pus culture, and systemic vancomycin was administered for one month. Although the abscess recurred, it was successfully treated with percutaneous catheter drainage and systemic vancomycin administration for three months, without the need for instrumentation removal. The patient remained asymptomatic throughout two years of follow-up. PMID:26665118

    Mycobacterium kansasii is a photochromogenic, slow-growing mycobacterium species that can cause pulmonary infection in patients with predisposing lung diseases, as well as extrapulmonary or disseminated disease in immunosuppressed patients. We describe a patient with a myelodysplastic syndrome, disseminated M kansasii infection, and ruptured aortic aneurysm. He had a recent diagnosis of mycobacterium cavitary lung lesions and was transferred to our facility for possible surgical intervention of an aortic aneurysm. Few hours after admission, the patient suddenly collapsed and died despite resuscitation efforts. A complete autopsy was performed and showed ruptured ascending aortic pseudoaneurysm with hemopericardium, disseminated necrotizing and nonnecrotizing granulomas with acid-fast bacilli in the aortic wall, lungs, heart, liver, spleen, and kidneys. Further genetic studies were consistent with monocytopenia and mycobacterial infection syndrome. PMID:25537975

    We report a 50-year-old male patient with diabetes mellitus and hypertension who presented with low-grade fever, anuria and renal failure. He had no prior history of nephropathy and retinopathy. Since anuria persisted, a renal biopsy was performed using automated gun, under ultrasound guidance. Two hours after the renal biopsy was performed, the patient developed severe left loin pain that required analgesics and sedatives. Ultrasound of the abdomen performed immediately, two hours and four hours after the biopsy, did not reveal any hematoma. The hemoglobin was stable when the patient developed loin pain, but after eight hours decreased to 9.1 g/dL, and computed tomography scan of the abdomen revealed a big peri-nephric hematoma around the left kidney. He was managed with blood transfusions and a selective angiogram was done. It revealed a pseudoaneurysm and arterio-venous fistula from the segmental artery of lower pole of the left kidney; both were closed by using microcoils and liquid embolic agent N-butyl-cyanoacrylate (NBCA). The only risk factor the patient had at the time of renal biopsy was severe renal failure. Our case suggests that severe loin pain immediately after renal biopsy in a patient with renal failure warrants careful follow-up of hemoglobin and imaging, even if initial imaging is normal. Further fall of hemoglobin necessitates early evaluation with angiogram, which helps in diagnosing the treatable, although rare, complications like pseudoaneurysm and arterio-venous fistula.

    While risk scores are invaluable tools for adapted preventive strategies, a significant gap exists between predicted and actual event rates. Additional tools to further stratify the risk of patients at an individual level are biomarkers. A surrogate endpoint is a biomarker that is intended as a substitute for a clinical endpoint. In order to be considered as a surrogate endpoint of cardiovascular events, a biomarker should satisfy several criteria, such as proof of concept, prospective validation, incremental value, clinical utility, clinical outcomes, cost-effectiveness, ease of use, methodological consensus, and reference values. We scrutinized the role of peripheral (i.e. not related to coronary circulation) noninvasive vascular biomarkers for primary and secondary cardiovascular disease prevention. Most of the biomarkers examined fit within the concept of early vascular aging. Biomarkers that fulfill most of the criteria and, therefore, are close to being considered a clinical surrogate endpoint are carotid ultrasonography, ankle-brachial index and carotid-femoral pulse wave velocity; biomarkers that fulfill some, but not all of the criteria are brachial ankle pulse wave velocity, central haemodynamics/wave reflections and C-reactive protein; biomarkers that do no not at present fulfill essential criteria are flow-mediated dilation, endothelial peripheral arterial tonometry, oxidized LDL and dysfunctional HDL. Nevertheless, it is still unclear whether a specific vascular biomarker is overly superior. A prospective study in which all vascular biomarkers are measured is still lacking. In selected cases, the combined assessment of more than one biomarker may be required.

    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

    Abstract Aging increases oxidative stress and inflammation. Melatonin counteracts inflammation and apoptosis. This study investigated the possible protective effect of melatonin on the inflammatory and apoptotic response secondary to ischemia induced by blockade of the right middle cerebral artery (MCA) in aging male Wistar rats. Animals were subjected to MCA obstruction. After 24 h or 7 days of procedure, 14-month-old nontreated and treated rats with a daily dose of 10 mg/kg melatonin were sacrificed and right and left hippocampus and cortex were collected. Rats aged 2 and 6 months, respectively, were subjected to the same brain injury protocol, but they were not treated with melatonin. mRNA expression of interleukin-1 beta (IL-1β), tumor necrosis factor alpha (TNF-α), Bcl-2-associated death promoter (BAD), Bcl-2-associated X protein (BAX), glial fibrillary acidic protein (GFAP), B-cell lymphoma 2 (Bcl-2), and sirtuin 1 was measured by reverse transcription–polymerase chain reaction. In nontreated animals, a significant time-dependent increase in IL-1β, TNF-α, BAD, and BAX was observed in the ischemic area of both hippocampus and cortex, and to a lesser extent in the contralateral hemisphere. Hippocampal GFAP was also significantly elevated, while Bcl-2 and sirtuin 1 decreased significantly in response to ischemia. Aging aggravated these changes. Melatonin administration was able to reverse significantly these alterations. In conclusion, melatonin may ameliorate the age-dependent inflammatory and apoptotic response secondary to ischemic cerebral injury. PMID:26594596

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery.

    We present 2 rare cases of patients with uncontrolled hemorrhagic shock induced by traumatic ascending aortic pseudoaneurysm rupture into the esophagus. Two men were presented to the hospital after traffic accidents. Their chest radiograph showed no obvious signs of aortic damage or aortic pseudoaneurysms but only a small amount of high-density shadow in the mediastinum and no specific clinical signs besides chest tightness or chest tenderness. The first case was misdiagnosed as pulmonary contusion and pleural effusion, and the second case was misdiagnosed as mediastinal lesions in the mediastina. They were given symptomatic and supportive treatment. Unfortunately, they died suddenly after >1 month of traumatic accident. At autopsy, ascending aortic pseudoaneurysms that broke into the esophagus and multiple organ hematocele were detected by gross examination. In histopathological examination, inflammatory cells and proliferated fibrous connective tissue were detected in the ascending aortic pseudoaneurysms, and the pathological gastrointestinal bleeding was not seen. The drugs and poisons were not found on toxicological analysis. The 2 patients died as a result of hemorrhagic shock from traumatic ascending aortic pseudoaneurysm rupture into the esophagus. We suggest that thoracic surgeon should be aware of the possibility of aortic injury after chest trauma to reduce misdiagnosis and prevent similar accidents.

    Joint hemorrhages are very common in patients with severe hemophilia. Inhibitors in patients with hemophilia are allo-antibodies that neutralize the activity of the clotting factor. After total knee replacement, rare intra-articular bleeding complications might occur that do not respond to clotting factor replacement. We report a 40-year-old male with severe hemophilia A and high responding inhibitors presenting with recurrent knee joint hemorrhage after bilateral knee prosthetic surgery despite adequate clotting factor treatment. There were two episodes of marked postoperative hemarthrosis requiring extensive use of subsititution therapy. Eleven days postoperatively, there was further hemorrhage into the right knee. Digital subtraction angiography diagnosed a complicating pseudoaneurysm of the inferior lateral geniculate artery and embolization was successfully performed. Because clotting factor replacement therapy has proved to be excessively expensive and prolonged, especially in patients with inhibitors, we recommend the use of cost-effective early angiographic embolization.

    This paper describes four cases of visceral artery aneurysms (VAAs) successfully treated with endovascular stent-grafts and discusses the endovascular approach to VAAs and the long-term results. Four balloon expandable stent-grafts were used to treat three splenic artery aneurysms and one bleeding common hepatic artery pseudoaneurysm. The percutaneous access site and the materials were chosen on the basis of CT angiography findings. In all cases the aneurysms were successfully excluded. In one case a splenic infarction occurred, with nonrelevant clinical findings. At 16- to 24-month follow-up three patients had patent stents and complete exclusion and shrinkage of the aneurysms. One patient died due to pancreatitis and sepsis, 16 days after successful stenting and exclusion of a bleeding pseudoaneurysm. We conclude that endovascular treatment using covered stent-grafts is a valid therapeutic option for VAAs. Multislice CT preoperative study helps in planning stent-graft positioning.

    Purpose. To assess the effectiveness of endovascular treatment of anastomotic pseudoaneurysms (APAs) following aorto-iliac surgical reconstruction. Materials. We retrospectively evaluated 21 men who, between July 2000 and March 2006, were observed with 30 APAs, 13 to the proximal anastomosis and 17 to the distal anastomosis. The patients had had previous aorto-iliac reconstructive surgery with a bypass due to aneurysm (15/21) or obstructive disease (6/21). The following devices were used: 12 bifurcated endoprostheses, 2 aorto-monoiliac, 4 aortic extenders, 1 stent-graft leg, and 2 covered stents. Follow-up was performed with CT angiography at 1, 3, and 6 months after the procedure and yearly thereafter. Results. Immediate technical success was 100%. No periprocedural complications occurred. Four patients died during follow-up from causes not related to APA, and 1 (treated for prosthetic-enteric fistula) from sepsis 3 months after the procedure. During a mean follow-up of 19.7 months (range 1-72 months), 2 of 21 occlusions of stent-graft legs occurred 3 and 24 months after the procedure (treated with thrombolysis and percutaneous transluminal angioplasty and femorofemoral bypass, respectively) and 1 type I endoleak. Primary clinical success rate was 81% and secondary clinical success was 91%. Conclusion. Endovascular treatment is a valid alternative to open surgery and can be proposed as the treatment of choice for APAs, especially in patients who are a high surgical risk. Further studies with larger series and longer follow-up are necessary to confirm the long-term effectiveness of this approach.

    Purpose: To investigate the percutaneous endovascular management of visceral aneurysms (VA) and visceral pseudoaneurysms (VPA) treated in three European interventional radiology departments. Methods: Patient archives from the department's databases were examined and retrospectively analyzed. Patients diagnosed between 2000 and 2010 with VA and/or VPA, confirmed by computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography and treated exclusively with percutaneous endovascular methods, were included in the study. The study's primary end points were procedural technical success, target lesion reintervention rate, and periprocedural mortality rate. Secondary end points included major and minor complications rates. Results: The medical records of 54 patients (41 male, mean age 55 {+-} 18.1 years) with 58 VAs or VPAs and treated with various percutaneous endovascular therapeutic modalities were analyzed. In total, 21 VAs (mean diameter 49.4 {+-} 21 mm, range 20-100 mm) and 37 VPAs (mean diameter 25.1 {+-} 14.6 mm, range 8-60 mm) were treated. Procedural technical success was achieved in 100% of the cases, while target lesion reintervention rate was 6.1% (2 of 33) and 14.2% (3 of 21) in the VPA and VA groups, respectively. Mean clinical follow-up period was 19.1 {+-} 21.4 months. Overall periprocedural mortality rate was 3% (1 of 33) in the VPA group and 0% (0 of 21) in the VA group. Conclusion: Percutaneous endovascular treatment of VAs and VPAs is safe and effective with low morbidity and mortality. There is a small but significant reintervention rate, particularly for true aneurysms; dedicated follow-up imaging is recommended. Successful aneurysm exclusion was achieved in all cases with a second procedure.

    A 22-year-old man presented with a sudden backache and paraplegia (ASIA = B). Magnetic resonance imaging showed an anterior pan-spinal epidural haematoma. Digital subtraction angiography was performed and ruled out an underlying vascular malformation but showed an active contrast media leakage into the T-4 ventral epidural space with a pattern of pseudo-aneurysm. A rupture of a T-4 retrocorporeal artery was considered as the aetiology, possibly caused by a haemorrhagic sub-adventitial dissection. Treatment consisted in the embolisation of both the pseudo-aneurysm and the parent artery with liquid acrylic glue, followed by neurosurgical decompression in emergency. The patient had totally recovered (ASIA = E) by the 10-month clinical follow-up.

    Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare but potentially lethal complication, mainly after aortic root endocarditis or surgery. Usually it originates from a dehiscence in the mitral-aortic intervalvular fibrosa and it arises posteriorly to the aortic root. Due to these anatomical features, its imaging assessment is challenging and surgical repair requires complex procedures. An unusual case of LVOT pseudoaneurysm is described. It was detected by transthoracic ecocardiography 7 months after aortic root replacement for acute endocarditis. Multidetector computed tomography (MDCT) confirmed the presence of a pouch located between the aortic root and the right atrium. Computed tomography also detected the origin of the pseudoaneurysm from the muscular interventricular septum of the LVOT, rather below the aortic valve plane. It was repaired with an extracardiac surgical approach, sparing the aortic root bioprosthesis previously implanted. The high-resolution three-dimensional details provided by the preoperative MDCT allowed us to plan a simple and effective surgical strategy.

    Acute aortic syndromes, encompassing intramural hematoma, penetrating ulcer, and pseudoaneurysm, are best demonstrated by angiographic CT and magnetic resonance imaging. These imaging modalities provide an accurate evaluation and allow timely therapies of these frequently symptomatic lesions, thus reducing their morbidity and mortality. The inflammatory pathogenesis of these acute aortic syndromes may exhibit positive PET findings predictive of prognosis and outcomes of these vascular events. The authors present a case of PET/CT imaging showing asymptomatic intramural hematomas with penetrating ulcer and saccular pseudoaneurysm of the proximal abdominal aorta.

    Polyarteritis nodosa (PAN) is a vasculitis, which often involves small and medium sized visceral arteries. This condition may result in multifocal aneurismal formation and end-organ damage. Uncommonly, PAN may present with rupture of hepatic artery aneurysms. Here, we report a rare case of a ruptured intrahepatic aneurysm associated with PAN. A 79-year-old woman presenting with abdominal pain had CT scan of the abdomen, which revealed hematoma in the right hepatic lobe. Visceral angiogram confirmed pseudo-aneurysm of a right hepatic arterial branch, and this was managed with endovascular coil embolization. The diagnosis of PAN was made and corticosteroid therapy was initiated. We also performed a literature review to define this condition's demographics, clinical presentations, and appropriate management. The review revealed 17 published cases of ruptured PAN-related intrahepatic aneurysms. We conclude that unexplained findings of visceral arterial aneurysms should prompt investigations for vasculitis as the etiology.

    Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percutaneous closure of an aortic pseudoaneurysm located in the left ventricular outflow tract by using a type II Amplatzer vascular plug in a patient in whom open surgical repair was not recommended.

    Pseudoaneurysm of the right ventricle outflow tract (RVOT) is a rare complication in pediatric cardiac surgery. We report a patient who developed a right ventricular pseudoaneurysm 8 months after RVOT enlargement using a pericardial patch for infundibular pulmonary stenosis. Our patient was born with severe pulmonary valvular stenosis and treated with percutaneous balloon valvotomy in the neonatal period. Six months later, she developed infundibular pulmonary stenosis, which required surgical resection of right ventricle infundibular trabeculations and bovine pericardial patch enlargement. The postoperative period was normal. She was readmitted to hospital 5 months later complaining of wheezing, coughing and shortness of breath. Echocardiography showed a huge aneurysmal dilatation of the outflow patch in connection with the right ventricular cavity. The patient underwent resection of the pseudoaneurysm and former patch, followed by interposition of a bovine jugular vein conduit between the RVOT and pulmonary bifurcation. The early postoperative period was uncomplicated. On echocardiography, no significant residual gradient was measured through the conduit and there was no insufficiency of the valve. RVOT reconstruction with patch enlargement, homograft or conduit implantation can be the origin of pseudoaneurysms. Although their incidence is rare, they are often asymptomatic before becoming quite large and causing compression symptoms as in our patient with respiratory complaints due to airway compression. It is important to follow up these patients closely, especially in the first year after surgery since most aneurysms develop within 6 months of surgery. PMID:20824590

En una endoscopia del tubo digestivo alto se encontró sangrado activo en la región del fundus gástrico, que no pudo controlarse. La angio-tomografía axial computada abdominal confirmó el diagnóstico de pseudoaneurisma de la arteria esplénica, en íntimo contacto con la pared posterior del estómago y quizá fistulizado al mismo. La paciente se intervino con carácter urgente realizándose esplenopancreatectomía distal y fistulorrafia. Conclusión: en raras ocasiones la ruptura de un pseudoaneurisma de la arteria esplénica puede iniciarse como una hemorragia digestiva alta, que puede ser letal si no es tratada con urgencia.

    Le complicanze vascolari dopo il trapianto renale non sono comuni, e nella maggior parte dei casi si presentano nel periodo post-trapianto precoce. Gli pseudoaneurismi arteriosi coinvolgono l’anastomosi arteriosa del rene trapiantato e nella maggior parte dei casi riconoscono una eziologia micotica. Una donna di 62 anni, che è stata sottoposta otto mesi prima ad un trapianto renale, presentava un vago dolore in fossa iliaca destra. L’ecografia del rene trapiantato dimostrava la presenza di un’area ipoecogena in corrispondenza dell’ilo renale, che all’ecocolordoppler appariva riccamente vascolarizzata. La tomografia computerizzata confermava la diagnosi di pseudo-aneurisma anastomotico di 33 mm di diametro, coinvolgente l’arteria del rene trapiantato. La paziente è stata dunque sottoposta a intervento chirurgico di aneurismectomia, con successivo bypass fra arteria renale del rene trapiantato e arteria iliaca interna. La continuità arteriosa iliaca è stata dunque ristabilita attraverso un by-pass iliaco-esterno-femorale comune in vena safena invertita. L’ecocolordoppler intraoperatorio dimostrava la corretta perfusione del graft renale e la corretta pervietà del by-pass iliacofemorale. Il decorso post-operatorio è stato privo di complicanze significative, eccettuata una linforrea inguinale risolta spontaneamente in 22a giornata post-operatoria. Sei mesi dopo la procedura, la paziente è in ottime condizioni generali, con una funzionalità renale conservata e una corretta pervietà del by-pass iliacofemorale. Lo pseudo-aneurisma dell’arteria renale rappresenta una rara complicanza del trapianto renale. Nella maggior parte dei casi riconosce una eziologia micotica, spesso a causa di contaminazione diretta del graft durante le procedure di prelievo o conservazione dell’organo. Il trattamento è molto complesso, e in molti casi richiede l’espianto del graft. Tuttavia, in alcuni casi selezionati, è possibile eseguire il trattamento dell’aneurisma, preservando il rene trapiantato, come nel caso da noi descritto. In conclusione, lo pseudoaneurisma dell’arteria renale è una complicanza rara ma potenzialmente letale del trapianto renale. L’intervento chirurgico di resezione dell’aneurisma, sebbene tecnicamente complesso, consente di preservare la funzionalità del rene trapiantato.

    Mitral valve ring abscess and ventricular pseudoaneurysm are rare complications of infective endocarditis. We describe the case of a 58-year-old man who was admitted to our hospital with sepsis caused by Staphylococcus aureus and in whom tricuspid and mitral valve endocarditis developed within 2 weeks. Despite widespread antibiotic therapy, the endocarditis proceeded to form a mitral valve ring abscess and a left ventricular pseudoaneurysm. The diagnosis was set by repeated multiplane transesophageal echocardiography and confirmed by heart surgery.

    Drug addiction has been one of the serious social problems. The peripheral phlebitis caused by drug injection is common, but the occurrence of pseudoaneurysm with infection of femoral artery from injection injury was rarely reported in China. From January 1995 to March 1996, six cases of injury of femoral artery with infection from heroine injection were admitted. The characteristics of the injury were described. The therapeutic measures and details of attention to be needed were discussed. It was concluded that this type of injury was different from the injury caused in agricultural, industrial or traffic accidents. The treatment of choice depended upon the type of injury.

    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

    2015-01-01

    Complex regional pain syndrome (CRPS) is a chronic pain disorder characterized by severe pain and vasomotor and pseudomotor changes. Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms is a recent advance in vascular surgery that has allowed repair of AAA while offering reduced intensive care unit and hospital lengths of stay, reduced blood loss, fewer major complications, and more rapid recovery. Pseudoaneurysms are a rare complication of an EVAR procedure that may result in a wide range of complications. The present report examines CRPS type II as a novel consequence of pseudoaneurysm formation from brachial artery access in the EVAR procedure. To our knowledge, this is the first reported case of CRPS type II presentation as sequelae of an EVAR procedure. PMID:25650247

Isolated injury of the hepatic artery has been rarely reported in the literature. Such injury may be lethal and requires immediate diagnosis and management. This report describes an unusual case of blunt abdominal trauma resulting in hepatic and gastroduodenal artery dissection, with pseudoaneurysm formation complicated by active upper gastrointestinal bleeding. The injury was managed by transcatheter embolisation. Awareness of this diagnosis should facilitate management of similar trauma cases.

    A false aneurysm of visceral arteries is a life-threatening pathology sufficiently difficult to treat. Open operations are characterised by a large scope, considerable surgical injury and accompanied by a high rate of serious complications. The development of the technology of superselective catheterization of blood vessels, creation of specialized microcatheters, glue composites and various types of spirals made it possible to treat this severe pathology without resorting to open operations. The work deals with a brief literature review concerning epidemiology, methods of diagnosis and treatment of pseudoaneurysms of visceral arteries, followed by presenting three clinical case reports concerning successful treatment of posttraumatic false aneurysms of the right hepatic and splenic arteries, as well as an aneurysm of the renal artery. Both immediate and remote results of endovascular interventions in these patients are followed up, demonstrably showing possibilities of endovascular technologies in treatment of the pathology involved.

    Hepatic aneurysms are a rare sequela of vascular abnormalities in the liver, including trauma, infection, necrotizing vasculitis such as polyarteritis nodosa (PAN), and iatrogenic and arterial mediolysis. Presentation with intra-abdominal hemorrhage is associated with a high mortality rate. We describe life-saving transcatheter coil embolization of multiple isolated ruptured hepatic pseudoaneurysms in a patient with no history or clinical findings of PAN. We present angiographic findings and intra-arterial transcatheter embolization techniques in the treatment of ruptured large hepatic artery aneurysms. Endovascular specialists should recognize that PAN could present with classic angiographic findings and, in some cases, as life-threatening ruptured isolated hepatic artery aneurysms as its first presentation.

    Iatrogenic arterial injury is an uncommon but recognized complication of posterior spinal surgery. The spectrum of injuries includes vessel perforation leading to hemorrhage, delayed pseudoaneurysm formation, and threatened perforation by screw impingement on arterial vessels. Repair of these injuries traditionally involved open direct vessel repair or graft placement, which can be associated with significant morbidity. We identified five patients with iatrogenic arterial injury during or after posterior spinal surgery between July 2004 and August 2009 and describe their endovascular treatment. Intraoperative arterial bleeding was encountered in two patients during posterior spinal surgery. The posterior wounds were packed, temporarily closed, and the patient was placed supine. In both patients, angiography demonstrated arterial injury necessitating repair. Covered stent grafts were deployed through femoral cutdowns to exclude the areas of injury. In three additional patients, postoperative computed tomography imaging demonstrated pedicle screws abutting/penetrating the thoracic or abdominal aorta. Angiography or intravascular ultrasound imaging, or both, confirmed indention/perforation of the aorta by the screw. Aortic stent graft cuffs were deployed through femoral cutdowns to cover the area of aortic contact before hardware removal. All five patients did well and were discharged home in good condition. Endovascular repair of arterial injuries occurring during posterior spinal procedures is feasible and can offer a safe and less invasive alternative to open repair.

    We present a patient with Ehlers-Danlos syndrome type IV (EDS IV) with a carotid dissecting pseudoaneurysm causing severe carotid stenosis. This lesion was treated endovascularly. Unfortunately, the patient died of remote vascular catastrophes (intracranial hemorrhage and abdominal aortic rupture). This unique case illustrates the perils of endovascular treatment of EDS IV patients and the need for preoperative screening for concomitant lesions. It also shows that a dissecting pseudoaneurysm can feasibly be treated with a covered stent and that closure is effective using Angioseal in patients with EDS IV.

    Pseudoaneurysm of the ascending aorta is rare in infants, with few cases reported in the literature. These aneurysms are usually mycotic, occurring after cardiac surgery, or caused by mediastinitis. They have high risk of spontaneous rupture. Surgery is usually complex because of the need for peripheral cannulation in small infants. We report an ascending aortic pseudoaneurysm in a less than 3-month-old infant that occurred within a month after repair of type 2 truncus arteriosus and was managed successfully with a modified cardiopulmonary bypass strategy.

He had previously undergone emergency exclusion bypass of a ruptured pseudoaneurysm developing post-aortic coarctation repair. Computed tomography scan showed persistent filling of pseudoaneurysm sac from proximal and distal aortic ligature sites tied during previous exclusion bypass surgery. Successful exclusion of aneurysm was achieved by using 3 vascular plug devices (1 Amplatzer plug II and 2 Amender patent ductus arteriosus occluder devices). We also review types of Amplatzer vascular plugs and their use in peripheral vascular interventions.

    Objectives. A symptomatic renal pseudoaneurysm (RPA) is a severe complication after open partial nephrectomy (OPN). The aim of our study was to assess incidence and risk factors for RPA formation. Furthermore, we present our management strategy. Patients and Methods. Clinical records of consecutive patients undergoing OPN were assessed for surgical outcome and postoperative complications. Renal masses were risk stratified for tumor complexity according to the PADUA score. Uni- and multivariate analysis for symptomatic RPAs were performed using the t-tests and logistic regression. Results. We identified 233 patients treated with OPN. Symptomatic RPAs were observed in 13 (5.6%) patients, on average 14 (4–42) days after surgery. Uni- and multivariate analysis identified tumor complexity to be an independent predictor for symptomatic RPAs (p = 0.004). There was a significant correlation between RPAs and transfusion and the duration of stay (p < 0.001 and p = 0.021). Symptomatic RPAs were diagnosed with CT scans and successfully treated with arterial embolization. Discussion. Symptomatic RPAs are not uncommon after OPN for high-risk renal masses. A high nephrometry score is a predictor for this severe complication and may enable a risk-stratified followup. RPAs can successfully be located by CT angiography, which enables targeted angiographic treatment. PMID:26539549

    Failure of a vascular closure device most commonly results in a hemorrhage or pseudoaneurysm formation. In this paper a rare case of severe acute limb ischemia following incorrect deployment of a clip-based closure device (Starclose SE, Abbott Vascular) in a 31-year-old woman is presented. Symptoms of acute limb ischemia occurred at the start of the ambulation, 6 h after completion of the procedure. Because of the severity of ischemia the patient was treated surgically, and limb perfusion was successfully restored. An attempt of closure of an inadvertently punctured narrow superficial femoral artery was identified as the cause of this complication. PMID:27458492

    The middle meningeal artery (MMA) is a very important artery in neurosurgery. Many diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (AVF), moyamoya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine and meningioma, can involve the MMA. In these diseases, the lesions occur in either the MMA itself and treatment is necessary, or the MMA is used as the pathway to treat the lesions; therefore, the MMA is very important to the development and treatment of a variety of neurosurgical diseases. However, no systematic review describing the importance of MMA has been published. In this study, we used the PUBMED database to perform a review of the literature on the MMA to increase our understanding of its role in neurosurgery. After performing this review, we found that the MMA was commonly used to access DAVFs and meningiomas. Pseudoaneurysms and true aneurysms in the MMA can be effectively treated via endovascular or surgical removal. In MMD, the MMA plays a very important role in the development of collateral circulation and indirect revascularization. For recurrent CDSHs, after burr hole irrigation and drainage have failed, MMA embolization may be attempted. The MMA can also contribute to the occurrence and treatment of migraines. Because the ophthalmic artery can ectopically originate from the MMA, caution must be taken to avoid causing damage to the MMA during operations. PMID:27766029

    We report here a case of cervical carotid artery aneurysm. This 37-year-old male suffered from acute neck swelling when he was taking lunch after physical work. Ultrasonography demonstrated a cervical pseudoaneurysm and a jet flow, which was blowing into the dome from the carotid artery. Angiogram revealed an aneurysm with a diameter of 3 cm at the bifurcation of the common carotid artery. Coil embolization using double-catheter technique was performed and complete occlusion of the aneurysm was obtained without any complications. The patient returned to his normal life. Cervical carotid artery aneurysms are rare and they induce pain by swelling in the neck, hoarseness, swallowing disturbance, hemorrhage, and cerebral ischemia due to embolism. In case of a cervical carotid artery aneurysm, safe and effective treatments are required and endovascular treatment should be considered. Although stent-assisted coil embolization or covered-stent placement were reported as an effective treatment for cervical aneurysms, coil embolization without using a stent was performed in this particular patient who is a young, blue-collar worker because the avoidance of long-term anti-platelet therapy was desirable. Preoperative evaluation is important to select adequate treatment. PMID:23732763

Despite clinical trial evidence and consensus that these therapies improve survival in high-risk patients, data suggest that there is wide variation in the delivery of guideline-based care. To investigate whether evidence-based assessment of provider practice patterns can impact the delivery of quality cost-effective care, Merck and Company, in conjunction with leading cardiology group practices, the University of North Carolina at Chapel Hill, and Medical Review of North Carolina developed an ambulatory medical record abstraction study. This quality assurance initiative was conducted at practices beginning in the spring of 1996 and continues. Medical records and administrative claims of patients with ischemic heart disease or heart failure were abstracted by a healthcare consulting organization to maintain patient and physician confidentiality. As of mid-July 1997, 626 group practices had completed the medical record abstraction process, with > 1,136 practices participating at some stage of the project; >6,000 physicians participated in the project and >270,000 patients charts were abstracted. Analysis of these data will provide insight and benchmark patterns of care in the pharmacologic management of heart failure and CAD. This project represents a unique collaboration between a pharmaceutical company, an academic institution, a Peer Review Organization, and practicing physicians, to support evidence

  19. Blood Flow in Arteries

    NASA Astrophysics Data System (ADS)

    Ku, David N.

    Blood flow in arteries is dominated by unsteady flow phenomena. The cardiovascular system is an internal flow loop with multiple branches in which a complex liquid circulates. A nondimensional frequency parameter, the Womersley number, governs the relationship between the unsteady and viscous forces. Normal arterial flow is laminar with secondary flows generated at curves and branches. The arteries are living organs that can adapt to and change with the varying hemodynamic conditions. In certain circumstances, unusual hemodynamic conditions create an abnormal biological response. Velocity profile skewing can create pockets in which the direction of the wall shear stress oscillates. Atherosclerotic disease tends to be localized in these sites and results in a narrowing of the artery lumena stenosis. The stenosis can cause turbulence and reduce flow by means of viscous head losses and flow choking. Very high shear stresses near the throat of the stenosis can activate platelets and thereby induce thrombosis, which can totally block blood flow to the heart or brain. Detection and quantification of stenosis serve as the basis for surgical intervention. In the future, the study of arterial blood flow will lead to the prediction of individual hemodynamic flows in any patient, the development of diagnostic tools to quantify disease, and the design of devices that mimic or alter blood flow. This field is rich with challenging problems in fluid mechanics involving three-dimensional, pulsatile flows at the edge of turbulence.

    Background Segmental arterial mediolysis (SAM) is a rare non-atherosclerotic, non-inflammatory vascular disorder varying widely in clinical course. The purpose of this study is to analyze detailing clinical and imaging manifestations over time in patients with SAM through a literature review and to suggest an optimal management strategy. Methods A retrospective review of eight consecutive patients diagnosed with SAM between January, 2000 and January, 2012 was conducted. All presented with acute-onset abdominal or flank pain. Clinical features, imaging studies, and laboratory findings served as grounds for diagnosis, having excluded more common conditions (ie, fibromuscular dysplasia, collagen vascular disorders, or arteritis). CT angiography was done initially and repeated periodically (Week 1, Month 3, then yearly). Treatment was conservative, utilizing endovascular intervention as warranted by CT diagnostics. In a related systematic review, all English literature from 1976 to 2015 was screened via the PubMed database, assessing patient demographics, affected arteries, clinical presentations, and treatment methods. Findings Ultimately, 25 arterial lesions identified in eight patients (median age, 62.8 years; range, 40–84 years) were monitored for a median period of 26 months (range, 15–57 months). At baseline, celiac axis (3/8, 37.5%), superior mesenteric (4/8, 50%), and common hepatic (2/8, 25%) arteries were involved, in addition to isolated lesions of right renal, splenic, right colic, middle colic, gastroduodenal, left gastric, right gastroepiploic, proper hepatic, right hepatic, and left hepatic arteries. Compared with prior publications, celiac axis and superior mesenteric artery were more commonly affected in cohort. Arterial dissections (n = 8), aneurysms (n = 5), stenoses or occlusions (n = 4), and a single pseudoaneurysm were documented. Despite careful conservative management, new splanchnic arterial lesions (n = 4) arose during follow

    Advances in computed tomography (CT) angiography have increased the sensitivity and specificity of detecting small branch arterial injuries in the extremities of trauma patients. However, it is unclear whether these patients should undergo surgery, angioembolization, or conservative watchful waiting. We hypothesized that uncomplicated small arterial branch injuries can be managed successfully with watchful waiting. A 10-year retrospective review of extremity CT angiograms with search findings of arterial "active extravasation" or "pseudoaneurysm" was performed at a level 1 county trauma center. Subgroup analysis was performed on those with isolated extremity injury and those with concurrent injuries. A total of 31 patients had CT-detected active extravasation (84 %) or pseudoaneurysm (16 %), 71 % of which were isolated vascular injuries. Of the patients evaluated, 71 % (n = 22) were managed with watchful waiting, 19 % (n = 6) with angioembolization, and 10 % (n = 3) with surgery. Watchful waiting complications included progression to alternative treatment (n = 1) and blood transfusions (n = 2). Complications of surgery included the inability to find active bleeding (n = 1) and postoperative psychosis (n = 1). Complications of angioembolization were limited to a postprocedure blood transfusion (n = 1). Patients with isolated vascular injuries had an average length of stay of 2.9 days, with management averages of the following: 2.7 days with watchful waiting (n = 16), 3.3 days with angioembolization (n = 3), and 3.7 days with surgery (n = 3). CT angiography has greatly increased the reported incidence of traumatic arterial injury in the extremity. We propose that small branch arterial injuries in the extremities can be managed successfully with watchful waiting and do not often require immediate embolization.

    We aimed to investigate the feasibility of using vessel-detection software to identify damaged arteries during endovascular embolization in five patients with visceral arterial hemorrhages. We used a software program originally developed to detect tumor feeder vessels in liver tumor embolization with C-arm computed tomography datasets to detect the vessels responsible for the arterial hemorrhages in patients with splenic artery pseudoaneurysms (n=2), lower gastrointestinal bleeding (n=2), and bladder tumor bleeding (n=1). In all cases, the injured vessel was identified accurately on a three-dimensional vascular map at the optimal working angle with a relatively short mean processing time of 118 s (range, 107-136 s). The operating angiographers used this information to direct the catheter into the damaged artery without sequential angiographic runs. The software analysis was also used to plan coil delivery to the most appropriate site in the injured artery. The results suggest that the vessel-detection software for liver tumor embolization can also be used to detect damaged vessels and to plan treatment strategies in endovascular embolization of visceral arterial hemorrhage.

The patient underwent stenting to treat the SMA occlusion and subsequent deployment of a custom-designed fenestrated endovascular stent-graft to treat the PAU involving the CT origin. Follow-up at 6 months after device placement demonstrated no complications, and there was complete thrombosis of the PAU and patency of the two branch vessels.

  6. Arterial Stiffness

    Stiffness of large arteries has been long recognized as a significant determinant of pulse pressure. However, it is only in recent decades, with the accumulation of longitudinal data from large and varied epidemiological studies of morbidity and mortality associated with cardiovascular disease, that it has emerged as an independent predictor of cardiovascular risk. This has generated substantial interest in investigations related to intrinsic causative and associated factors responsible for the alteration of mechanical properties of the arterial wall, with the aim to uncover specific pathways that could be interrogated to prevent or reverse arterial stiffening. Much has been written on the haemodynamic relevance of arterial stiffness in terms of the quantification of pulsatile relationships of blood pressure and flow in conduit arteries. Indeed, much of this early work regarded blood vessels as passive elastic conduits, with the endothelial layer considered as an inactive lining of the lumen and as an interface to flowing blood. However, recent advances in molecular biology and increased technological sophistication for the detection of low concentrations of biochemical compounds have elucidated the highly important regulatory role of the endothelial cell affecting vascular function. These techniques have enabled research into the interaction of the underlying passive mechanical properties of the arterial wall with the active cellular and molecular processes that regulate the local environment of the load-bearing components. This review addresses these emerging concepts. PMID:26587425

Magnetic resonance imaging showed high signal changes and loss of signal void in right internal carotid artery, later confirmed by Angiography as a dissection with pseudo-aneurysm. He was started on anticoagulation and made a good recovery on discharge. This case presents a unique combination of cranial nerve palsies due to internal carotid artery dissection (ICAD) and to our knowledge is the first reported case in the literature. Early recognition and institution of appropriate therapy is critical to prevention of ischemic stroke.

    Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately. PMID:27211205

Hypertensive patients with an age above 80 years should be treated in the same way as younger hypertensive patients if they are otherwise healthy and functionally independent. On the other hand frail elderly patients could have an increased morbidity and mortality with intensive blood pressure control. In patients with resistant hypertension spironolactone was the most effective drug when given in addition to their baseline drugs (ACE-inhibitor/angiotensin receptor antagonist, calcium channel blocker and thiazide diuretic).

    2014-01-01

    Introduction Raynaud’s phenomenon is episodic vasospasm of the peripheral vessels. It presents as episodic colour changes of the digits (sometimes accompanied by pain and paraesthesia), usually in response to cold exposure or stress. The classic triphasic colour change is white (ischaemia), then blue (de-oxygenation), then red (reperfusion). Raynaud’s phenomenon can be primary (idiopathic) or secondary to several different conditions and causes. When secondary (e.g., to systemic sclerosis), it can progress to ulceration of the fingers and toes. This review deals with secondary Raynaud’s phenomenon. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of surgical interventions in complicated secondary Raynaud’s phenomenon? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found two studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: botulinum toxin, simple debridement/surgical toilet of ulcers, peripheral sympathectomy (digital, digital plus sympathectomy of the ulnar and/or radial artery, ligation of the ulnar artery), cervical/thoracic sympathectomy, arterial reconstruction (venous graft, arterial graft, balloon angioplasty), and amputation PMID:25322727

    Abstract Rupture of jejunal artery aneurysm is a very rare event resulting in life-threatening hemorrhage in Behcet disease (BD). We report a case of ruptured jejunal artery aneurysm in a 35-year-old patient with BD. The patient had a 1-year history of intermittent abdominal pain caused by superior mesenteric artery aneurysm with thrombosis. Anticoagulation treatment showed a good response. Past surgical history included stenting for aortic pseudoaneurysm. On admission, the patient underwent an urgent operation due to sudden hemorrhagic shock. Resection was performed for jejunal artery aneurysm and partial ischemia of intestine. The patient was diagnosed with BD, based on a history of recurrent oral and skin lesions over the past 6 years. Treatment with anti-inflammatory medications showed a good response during the 8-month follow-up. An increased awareness of BD and its vascular complications is essential. Aneurysms in BD involving jejunal artery are rare, neglected and require proper management to prevent rupture and death. To our knowledge, this is the first reported case of jejunal artery aneurysm caused by BD. PMID:26559278

    PURPOSE We aimed to evaluate the imaging features of computed tomography (CT) and angiography and the efficacy of transcatheter arterial embolization (TAE) in patients with hemobilia of different iatrogenic causes. METHODS Thirty patients with hemobilia were divided into two groups according to their iatrogenic causes, i.e., group 1, 11 patients (36.7%) with transhepatic intervention and group 2, 19 patients (63.3%) with surgical procedures in the hilar area. Seventeen patients (56.7%) underwent abdominal contrast-enhanced CT before selective angiography. Polyvinyl alcohol particles, gelatin sponges, and coils were used for TAE. Data from the two groups were compared using Fisher’s exact test and the Mann-Whitney U test. RESULTS Contrast-enhanced CT showed a hematoma, extravasation of contrast material, and pseudoaneurysm. The bleeding source was determined by angiographic features in all patients, which were not significantly different between the two groups (P = 0.127), and pseudoaneurysm was the most common. The embolic material and number of coils used for TAE were significantly different between the two groups (P < 0.001), but the embolization was technically successful in all patients. The clinical success rate of the first embolization was 100% in group 1 vs. 84.2% in group 2. The overall clinical success rate of TAE was 100% in all patients. The complication rate was 63.6% in group 1 vs. 68.4% in group 2 (P = 1.000). CONCLUSION CT was useful in diagnosing hemobilia, and angiograms enabled determination of the bleeding source. Pseudoaneurysm was one of the most common angiographic features. TAE was successfully performed with different embolic materials on the basis of the iatrogenic cause and bleeding location.

    Purpose To evaluate the angiographic findings and embolotherapy in the management of traumatic renal arterial injury Methods This is a retrospective review of 22 patients with renal trauma who underwent arteriography and percutaneous embolization from December 1995 to January 2002. Medical records, imaging studies and procedural reports were reviewed to assess the type of injury, arteriographic findings and immediate embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians and by clinical chart review.Results Arteriography was performed in 125 patients admitted to a State Trauma Center with suspected internal bleeding. Renal arterial injury was documented in 22 and was the result of a motor-vehicle accident (10), auto-pedestrian accident (1), gunshot (4) or stab wounds (6) and a fall (1). Percutaneous renal arterial embolization was undertaken in 22 of 125 (18%) patients to treat extravasation (11), arterial pedicle rupture (5), abnormal arteriovenous (3) or arteriocalyceal (2) communication and pseudoaneurysm (3). One of the pseudoaneurysms and one of the arteriovenous fistulae were found in addition to extravasation. All 22 patients (16 men, 6 women) were hemodynamically stable, or controlled during arteriography and embolotherapy. Selective and/or superselective embolization of the abnormal vessels was performed using coils in 9 patients, microcoils in 9 patients and Gelfoam pledgets in 3 patients. In one patient Gelfoam pledgets mixed with polyvinyl alcohol (PVA) particles were used for embolization. Immediate angiographic evidence of hemostasis was demonstrated in all cases. Two initial technical failures were treated with repeat arteriography and embolization. There was no procedure-related death. There was no non-target embolization. One episode of renal abscess after embolization was treated by nephrectomy and 3 patients underwent elective post-embolization nephrectomy to prevent infection. Follow-up ranged

    Introduction: The purpose of the present study was to analyze complications following antegrade puncture of the common femoral artery (CFA) and the superficial femoral artery (SFA) using vascular closure systems (VCS). Methods: A single-center, retrospective study was performed after obtaining approval from the institutional review board and informed consent from all patients. At our center, the CFA or SFA are used for arterial access. All patients were evaluated clinically on the same day. If there was any suspicion of an access site problem, Duplex ultrasound was performed. Results: Access location was the CFA in 50 patients and the SFA in 130 patients. The sheath size ranged from 4F to 10F. Two patients had to be excluded because of lack of follow-up. Successful hemostasis was achieved in 162 of 178 cases (91 %). The following complications were observed in 16 patients (8.9 %): 4 pseudoaneurysms (2.2 %), 11 hematomas (6.2 %), and 1 vascular occlusion (0.5 %). The two pseudoaneurysms healed spontaneously, in one case an ultrasound-guided thrombin injection was performed, and one aneurysm was compressed manually. No further medical therapy was needed for the hematomas. The one vascular occlusion was treated immediately with angioplasty using a contralateral approach. No significant difference was noted between the CFA and the SFA group with respect to complications (p = 1.000). Conclusions: The use of closure devices for an antegrade approach up to 10F is feasible and safe. No differences in low complication rates were observed between CFA and SFA.

    The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.

    It has been known for some time that a relationship exists between the kidney and blood pressure. The renal origin of arterial hypertension has been demonstrated in different animal models resembling human hypertension, with data from humans seeming to confirm this hypothesis. On the other hand, the renal vasculature also suffers the consequences of arterial hypertension, and renal insufficiency can develop as a result of elevated blood pressure levels. Antihypertensive therapy can prevent the development of renal damage secondary to hypertension. For example, calcium antagonists possess specific renal effects that not only facilitate their antihypertensive capacity but also protect the kidney from the development of renal failure.

    Summary Background: Treatment of peripheral arterial diseases may be distinguished into conservative and interventional management; the latter is divided into surgical and endovascular procedures. Management of peripheral artery stenosis and occlusion with vascular stents is associated with the risk of late complications such as restenosis, stent fracture or dislocation. Case Report: A 62-year-old woman with generalized atherosclerosis, particularly extensive in lower limb arteries, was admitted to the Department of Angiology 11 months after having an endovascular procedure performed due to critical ischemia of left lower limb. Because of stent occlusion, a decision to perform angiographic examination of lower limb arteries was made. Examination revealed occlusion of the superficial femoral artery along its entire length, including previously implanted stents. Distal stent was fractured with slight dislocation of the proximal segment. A decision was made to perform mechanical thrombectomy using a Rotarex system followed by a stent-in-stent placement procedure. Follow-up angiography and ultrasound scan performed 24 hours after the procedure revealed a patent vessel with satisfactory blood flow. Discussion: Nowadays, imaging diagnostics of peripheral artery stenosis involves non-invasive examinations such as ultrasound, minimally invasive examinations such as angio-MRI and MDCT, or invasive examinations such as DSA and IVUS. DSA examinations are used to confirm significant stenosis or occlusion of a vessel, particularly when qualifying a patient for endovascular treatment. Due to their anatomic location, the superficial femoral artery and the popliteal artery are subject to various forces e.g. those exerted by the working muscles. Mechanical thrombectomy and atherectomy are efficient methods of arterial recanalization used in the treatment of acute, subacute or even chronic occlusions or stenosis of peripheral vessels. Conclusions: Frequency of angioplasty and

    Abdominal aortic pseudoaneurysm (AAP) is a rare lesion, although traumatic aortic injury is described as one of the main causes; both the rupture as the surgical treatment of the defect has high morbidity and mortality. Therefore, endovascular treatment either by chemical embolization or exclusion of defect with devices has emerged as an alternative treatment. However, there are risks such as occlusion of visceral vessels near the neck of the defect, embolization material or aortic rupture. Therefore, the choice of material and method of approach should be planned carefully in each case. We report a patient who ten years after abdominal wound firearm was diagnosed with AAP 17 x 13 cm, with short neck originated close to the ostium of the celiac trunk at an acute angle with the aortic axis. We perform the exclusion of the defect with a device designed for closing atrial septal defect from the left brachial access due to the angulation of the neck defect. There were no complications. At 72 hours was granted discharge. A month later, CT scan control showed the false aneurysm of equal size and no residual flow. The monitoring to date is five months and the patient remained asymptomatic.

    Background Rupture of an anastomotic pseudoaneurysm after lower extremity prosthetic bypass is a rare problem, and the traditional mode of treatment has been open surgery. Case Description We report the endovascular management of a disrupted distal anastomosis of an above-knee femoro-popliteal Dacron bypass graft. Under local anesthesia and via a femoral cut-down, the Dacron graft was punctured and a 9 x 60 mm stent-graft was implanted resulting in successful pseudoaneurysm exclusion. The patient had an uneventful recovery. Conclusions Stent-grafting may offer quick and easy rescue options for such challenging peripheral vascular lesions. Hippokratia 2015; 19 (2):179-181.

    A report is made of 3 observations of vascular constrictions in the knee hollow of three young adults: two constrictions of the popliteal artery, one by abnormal insertion of a tendon of the gastrocnemius muscle and of the arterial passage, the other by a fibrous band surrounding the artery. In one observation, the disorder was revealed by acute ischemia of one limb. The third observation was of a sural phlebitis with secondary repetition at the constriction of the popliteal vein by Soleaire's arcade. In all cases examination using the Doppler effect, in baseline and especially dynamic position, gives a diagnosis and allows postoperative monitoring. Bilateral arteriography, both static and dynamic, allows a precise diagnosis to be given and reveals the extent of vascular lesions, which conditions the operative technique. Treatment is always surgical, with exploration of the contralateral side if a constriction is suspected, even if it is asymptomatic. PMID:3707018

    Imaging the pregnant patient presents a unique challenge to radiologist due to the risk of radiation to the conceptus (embryo/fetus). A rare case of a successfully recognized and treated pseudoaneurysm (PA) of the abdominal aorta is to be presented. The pseudoaneurysm occurred in the third trimester and had a favorable outcome for the mother and the baby. Emergent abdominal ultrasound (US) is the first modality in diagnostic algorithm for the rupture of aortic aneurysm in a pregnant woman. It provides the most rapid diagnostic information, although intestinal gas and abdominal tenderness may limit its accuracy. To confirm the findings, magnetic resonance angiography (MRA) or CT angiography (CTA) can be used. In our case, the diagnosis was established using a color Doppler ultrasonography of the abdomen and was later confirmed by a low dose CT scan of the abdominal aorta. MRA in such cases have some disadvantages. At many health centers, the monitoring of patients with acute ruptures is more difficult in the MR suite than at the CT scanner. MRA angiographic images are also subject to degradation by multiple artifacts and the visualization of the distal vasculature is suboptimal and inferior to the one done by CTA. Due to fetal movements, a small quantity of fresh blood can be overlooked by MR. MRA is often not available on a 24-hours basis, and the time required for making a diagnosis can preclude the use of MRA in an unstable patient. For this reason, we used a low dose CTA protocol to confirm the diagnosis. Low dose scanning protocols in CT can obtain sufficient diagnostic information while reducing the risk of radiation. A particular focus is put on the outline of new concepts for dose management and optimization. We used new approaches based on tube current modulation. The birth was induced by an urgent Caesarean section followed by a resection of a pseudoaneurysm and a reconstruction of the aorta with an end-to-end vascular prosthesis. PMID:26898082

    PurposeTo evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center.MethodsWe retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous arterial rupture or pseudoaneurysm with acute bleeding. All interventions used a percutaneous approach through a 5F or less introducer sheath. Embolic agents were microcoils and glue in 3 procedures, glue alone in 2, and microcoils alone in 2.ResultsFive consecutive vEDS patients were treated by 7 embolization procedures (4 women, mean age 29.8 years). All procedures were successfully performed. Two patients required a second procedure for newly arterial lesions at a different site from the first procedure. Four of the five patients were still alive after a mean follow-up of 19.4 (range 1–74.7) months. One patient died of multiple organ failure 2 days after procedure. Minor procedural complications were observed in 3 procedures (43 %), all directly managed during the same session. Remote arterial lesions occurred after 3 procedures (43 %); one underwent a second embolization, and the other 2 were observed conservatively. Puncture site complication was observed in only one procedure (14 %).ConclusionEmbolization for vEDS is a safe and effective method to manage life-threatening arterial rupture.

    Aortic coarctation is a frequent congenital defect requiring early surgical treatment. Late complications of these surgical procedures can be fatal as in the case of a ruptured anastomotic pseudoaneurysm. We present a case of a 49-year-old man presenting with hemorrhagic shock due to this complication who was successfully treated by endovascular techniques with implantation of two stent grafts. This case illustrates the fact that endovascular aortic repair is feasible, certainly less invasive and very efficient for this type of complication when used in an experienced center.

    Purpose. Although the majority of iatrogenic pseudoaneurysms (PSAs) are amenable to ultrasound (US)-guided thrombin injection, patients with those causing neuropathy, claudication, significant venous compression, or soft tissue necrosis are considered poor candidates for this option and referred to surgery. We aimed to test the effectiveness and feasibility of a novel percutaneous cyanoacrylate glue (NBCA-MS)-based technique for treatment of symptomatic and asymptomatic iatrogenic PSA. Material and Methods. During a 3-year period, we prospectively enrolled 91 patients with iatrogenic PSA [total n = 94 (femoral n = 76; brachial n = 11; radial n = 6; axillary n = 1)]. PSA were asymptomatic in 66 % of cases, and 34 % presented with symptoms due to neuropathy, venous compression, and/or soft tissue necrosis. All patients signed informed consent. All patients received NBCA-MS-based percutaneous treatment. PSA chamber emptying was first obtained by US-guided compression; superior and inferior walls of the PSA chamber were then stuck together using NBCA-MS microinjections. Successfulness of the procedure was assessed immediately and at 1-day and 1-, 3-, and 12-month US follow-up. Results. PSA occlusion rate was 99 % (93 of 94 cases). After treatment, mean PSA antero-posterior diameter decrease was 67 {+-} 22 %. Neuropathy and vein compression immediately disappeared in 91 % (29 of 32) of cases. Patients with tissue necrosis (n = 6) underwent subsequent outpatient necrosectomy. No distal embolization occurred, nor was conversion to surgery necessary. Conclusion. PSA treatment by way of NBCA-MS glue injection proved to be safe and effective in asymptomatic patients as well as those with neuropathy, venous compression, or soft-tissue necrosis (currently candidates for surgery). Larger series are needed to confirm these findings.

    Traumatic intracranial aneurysms are rare in adults but account for up to 33% of all aneurysms encountered in a pediatric population. The most common location of such lesions in children is the pericallosal or adjacent branch of the anterior cerebral artery, where a head impact exerts sudden decelerating shearing forces on the arteries tethered on the brain surface against an immobile falx cerebri, weakening the arterial wall. This action can lead to dissection of the damaged vascular layers, with resultant expansion of the affected site into a fusiform aneurysm. Pericallosal aneurysms following a penetrating intracranial injury have also been described, and the resultant lesion in some cases can be a pseudoaneurysm. The incidence of iatrogenic pericallosal artery aneurysms, however, is extremely rare. The authors describe the first reported case of a traumatic pericallosal artery aneurysm following transcallosal surgery. This 6-year-old boy underwent resection of a hypothalamic pilocytic astrocytoma, which was approached via the transcallosal corridor. A follow-up magnetic resonance image obtained within 1 year of surgery disclosed a small flow void off the right pericallosal artery, which was initially interpreted as residual tumor. Serial investigations showed the lesion enlarging over time, and subsequent angiography revealed a round 7-mm pericallosal artery aneurysm with an irregularly shaped 2- to 3-mm lumen. The aneurysm was difficult to treat with clip reconstruction or suturing of the affected segment, and an excellent outcome was ultimately achieved with resection of the lesion and autogenous arterial graft interposition. The authors also discuss the likely pathophysiology of the aneurysm and the surgical procedures undertaken to treat it.

  16. Endovascular Treatment of Complications of Femoral Arterial Access

    Endovascular repair of femoral arterial access complications is nowadays the treatment of choice in a group of patients who cannot tolerate vascular reconstruction and bleeding due to advanced cardiovascular disease. Endovascular procedures can be performed under local anesthesia, are well tolerated by the patient, and are associated with a short hospitalization time. Ninitinol stent technology allows for safe stent and stent-graft extension at the common femoral artery (CFA) level, due to increased resistance to external compression and bending stress. Active pelvic bleeding can be insidious, and prompt placement of a stent-graft at the site of leakage is a lifesaving procedure. Percutaneous thrombin injection under US guidance is the treatment of choice for femoral pseudoaneurysms (PAs); this can theoretically be safer with simultaneous balloon occlusion across the entry site of a PA without a neck or with a short and wide neck. In a few cases with thrombin failure due to a large arterial defect or accompanying arteriovenous fistula (AVF), a stent-graft can be deployed. The vast majority of catheter-induced AVFs can be treated effectively with stent-graft implantation even if they are located very close to the femoral bifurcation. Obstructive dissection flaps localized in the CFA are usually treated with prolonged balloon inflation; however, in more extensive dissections involving iliac arteries, self-expanding stents should be deployed. Iliofemoral thrombosis can be treated effectively with catheter-directed thrombolysis (CDT) followed by prolonged balloon inflation or stent placement. Balloon angioplasty and CDT can occasionally be used to treat stenoses and occlusions complicating the use of percutaneous closure devices.

    Introduction The placement of a Swan-Ganz catheter into the pulmonary artery may lead to a number of complications (2–17%). In less than 0.2% of cases Swan-Ganz catheterization results in serious vascular damage – pulmonary artery rupture (PAR). This paper presents two distinct forms of iatrogenic PAR treated endovascularly using different vascular devices. Aim To evaluate the effectiveness of endovascular treatment and the application of different types of vascular devices in the management of pulmonary artery rupture caused by Swan-Ganz catheterization. Material and methods In this retrospective study we evaluated 2 patients in whom Swan-Ganz catheter application was used for perioperative monitoring and resulted in pulmonary artery rupture. This complication was treated endovascularly by means of interventional cardiology. Results We report the cases of 2 patients with a pulmonary artery pseudoaneurysm formed in the perioperative period. In case 1, a single, 4-loop, 3 mm diameter coil was implanted. In case 2, a 5 mm Amplatzer Vascular Plug IV was applied. In both cases, the endovascular approach resulted in total occlusion of the feeding artery and reduced further extravasation of the blood. Conclusions Despite its extremely low incidence, iatrogenic PAR is a serious, life-threatening complication of Swan-Ganz catheterization that requires urgent attention. Among available methods of treatment, percutaneous embolization is a relatively quick, safe, accurate and highly effective alternative to traumatizing surgery. PMID:27279873

    Background— Bilateral internal thoracic arteries (BITA) have demonstrated superior patency and improved survival in patients undergoing coronary artery bypass grafting. However, the optimal configuration for BITA utilization and its effect on long-term outcome remains uncertain. Methods and Results— We randomly assigned 304 patients undergoing coronary artery bypass grafting using BITA to either in situ or Y grafting configurations. The primary end point was 3-year angiographic patency. Secondary end points included major adverse cardiac and cerebrovascular events (ie, death from any cause, stroke, myocardial infarction, or repeat revascularization) at 7 years. More coronary targets were able to be revascularized using internal thoracic arteries in patients randomized to Y grafting versus in situ group (3.2±0.8 versus 2.4±0.5 arteries/patient; P<0.01). The primary end point did not show significant differences in graft patency between groups. Secondary end points occurred more frequently in the in situ group (P=0.03), with 7-year rates of 34±10% in the in situ and 25±12% in the Y grafting groups, driven largely by a higher incidence of repeat revascularization in the in situ group (14±4.5% versus 7.4±3.2% at 7 years; P=0.009). There were no significant differences in hospital mortality or morbidity or in late survival, myocardial infarction, or stroke between groups. Conclusions— Three-year systematic angiographic follow-up revealed no significant difference in graft patency between the 2 BITA configurations. However, compared with in situ configuration, the use of BITA in a Y grafting configuration results in lower rates of major adverse cardiovascular and cerebrovascular events at 7 years.

    Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined. We present a 7-month-old infant with intermittent respiratory distress that did not improve with respiratory interventions. Echocardiogram suggested a double aortic arch. Cardiac CT angiogram confirmed a right arch and aberrant, stenotic left subclavian artery, dilation of the main pulmonary artery, and agenesis of the left thyroid lobe. Repeat echocardiograms were concerning for severely dilated coronary arteries. Given dilation, a rheumatologic workup ensued, only identifying few weakly positive autoantibodies. Further imaging demonstrated narrowing of the aorta below the renal arteries and extending into the common iliac arteries and proximal femoral arteries. Given a physical exam devoid of rheumatologic findings, only weakly positive autoantibodies, normal inflammatory markers, and presence of the coronary artery dilation, the peripheral artery narrowings were not thought to be vasculitic. This case illustrates the need to identify definitive anomalies related to Goldenhar Syndrome. Although this infant's presentation is rare, recognition of specific vascular findings will help differentiate Goldenhar Syndrome from other disease processes. PMID:26688769

    Purpose. To evaluate the safety and efficacy of stent placement for extracranial and intracranial arterial dissections. Methods. Eighteen patients underwent endovascular treatment of carotid and vertebral dissections using intraluminal stent placement. Five patients with arterial dissection were treated, 2 using one insertion of a single stent and 3 using placement of two stents. Patients with a dissecting aneurysm were treated as follows: 7 patients with insertion of one stent, 4 with placement of two stents, and 2 by stent-assisted Guglielmi detachable coil embolization. In the 18 patients in whom stenting was attempted, the overall success in reaching the target lesion was 94.4%. Of the 17 patients treated with stents, stent release and positioning were considered optimal in 16 (94%) and suboptimal in one (6%). In patients who underwent a successful procedure, all parent arteries were preserved. There were no instances of postprocedural ischemic attacks, new neurologic deficits, or new minor or major strokes prior to patient discharge. In follow up, all patients were assessed, using the modified Rankin scale, as functionally improved or of stable clinical status. The reduction in dissection-induced stenosis or pseudoaneurysm, the patency rate obtained at follow-up, and the lack of strokes (ischemic or hemorrhagic) suggest that stent placement offers a viable alternative to complex surgical bypass or reconstructive procedures. The long-term efficacy and durability of stent placement for arterial dissection remain to be determined in a larger series.

  7. Traumatic subclavian arterial rupture: a case report and review of literature

    PubMed Central

    2012-01-01

    Subclavian artery injuries represent an uncommon complication of blunt chest trauma, this structure being protected by subclavius muscle, the clavicle, the first rib, and the deep cervical fascia as well as the costo-coracoid ligament, a clavi-coraco-axillary fascia portion. Subclavian artery injury appears early after trauma, and arterial rupture may cause life-treatening haemorrages, pseudo-aneurysm formation and compression of brachial plexus. These clinical eveniences must be carefully worked out by accurate physical examination of the upper limb: skin color, temperature, sensation as well as radial pulse and hand motility represent the key points of physical examination in this setting. The presence of large hematomas and pulsatile palpable mass in supraclavicular region should raise the suspicion of serious vascular injury. Since the first reports of endovascular treatment for traumatic vascular injuries in the 90’s, an increasing number of vascular lesions have been treated this way. We report a case of traumatic subclavian arterial rupture after blunt chest trauma due to a 4 meters fall, treated by endovascular stent grafting, providing a complete review of the past twenty years’ literature.

    Purpose: To assess the feasibility and effectiveness of emergency endovascular treatment of acute arterial injuries after orthopedic surgery. Materials and Methods: Fifteen patients (mean age 68.3 years) with acute arterial injuries after orthopedic surgery were observed, in particular, 5 patients with pseudoaneurysm, 9 patients with active bleeding, and 1 patient with arterial dissection. Transarterial embolization (TAE) and positioning of covered and noncovered stents were the treatments performed. Follow-up after stent implantation (mean 36 months) was performed with color Doppler US (CDU) at 1, 3, 6, and 12 months and yearly thereafter. Plain X-ray was performed to evidence dislodgment or fracture of the graft. A minimum of 12 months' follow-up is available after TAE. Results: Immediate technical success was obtained in all cases. No major complications occurred. Overall clinical success rate was 100%. During mean follow-up, stent-graft occlusions did not occurred. No recurrence and/or consequence of TAE was registered during a minimum follow-up of 12 months. Conclusions: Percutaneous treatment is a feasible and safe tool for treating arterial injuries because it can provide fast and definitive resolution of the damage. This low-invasiveness approach can be proposed as first-line treatment in patients with acute injuries after orthopedic surgery.

    Four cases of cervical vertebral artery (VA) dissection are reported. In three patients VA dissection was associated with neck trauma. All patients were young or middle-aged (range 27 to 49 years). In two there was a history of migraine. Pain preceded neurological symptoms from hours to six weeks. Three patients had neurological deficits including elements of the lateral medullary syndrome, and one experienced recurrent transient ischaemic attacks in the vertebrobasilar territory. Angiographic findings included irregular stenosis, occlusion and pseudoaneurysm; in two patients VA abnormalities were bilateral. All patients were treated with anticoagulants and improved. In a review of 28 cases with traumatic dissection and 29 cases with spontaneous dissection of the VA reported in the literature, distinct clinical and angiographic features emerge. Aetiology remains obscure in most cases of spontaneous dissection and management is still controversial. Images PMID:1744639

  10. Patent arterial duct.

    Patent arterial duct (PAD) is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area) is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes). Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of pulmonary overcirculation

    Embolic disease is often overlooked as a cause of digital ischemia. Unilateral symptoms, in particular, should suggest the possibility of emboli arising from the subclavian or more distal upper extremity vessels. Emboli may originate in the subclavian artery as the result of atherosclerosis at its origin or arterial injury secondary to thoracic outlet compression. Arteriography can be useful in the identification of upper extremity emboli and their source, and should include studies of the aortic, arch, proximal subclavian artery, and digital arteries. Retrograde subclavian injections may be required to adequately demonstrate the origin of the subclavian artery. Magnification technique is often essential in differentiating small digital artery emboli from primary arterial diseases, such as Buerger disease or scleroderma.

    Purpose. To assess the efficacy and safety of the Exoseal vascular closure device for antegrade puncture of the femoral artery. Methods. In a prospective study from February 2011 to January 2012, a total of 93 consecutive patients received a total of 100 interventional procedures via an antegrade puncture of the femoral artery. An Exoseal vascular closure device (6F) was used for closure in all cases. Puncture technique, duration of manual compression, and use of compression bandages were documented. All patients were monitored by vascular ultrasound and color-coded duplex sonography of their respective femoral artery puncture site within 12 to 36 h after angiography to check for vascular complications. Results. In 100 antegrade interventional procedures, the Exoseal vascular closure device was applied successfully for closure of the femoral artery puncture site in 96 cases (96 of 100, 96.0 %). The vascular closure device could not be deployed in one case as a result of kinking of the vascular sheath introducer and in three cases because the bioabsorbable plug was not properly delivered to the extravascular space adjacent to the arterial puncture site, but instead fully removed with the delivery system (4.0 %). Twelve to 36 h after the procedure, vascular ultrasound revealed no complications at the femoral artery puncture site in 93 cases (93.0 %). Minor vascular complications were found in seven cases (7.0 %), with four cases (4.0 %) of pseudoaneurysm and three cases (3.0 %) of significant late bleeding, none of which required surgery. Conclusion. The Exoseal vascular closure device was safely used for antegrade puncture of the femoral artery, with a high rate of procedural success (96.0 %), a low rate of minor vascular complications (7.0 %), and no major adverse events.

    Purpose: The purpose of this study was to evaluate the effectiveness of percutaneous arterial embolization in patients with penetrating peripheral arterial trauma. Materials and Methods: Twelve patients with penetrating peripheral arterial trauma were treated with percutaneous arterial embolization between 2002 and 2007. All injuries were secondary to penetrating stab wounds. Active bleeding (eight patients), recurrent bleeding episodes (one patient), persistent pain and mass (one patient), leg edema, claudication, swelling (one patient), local hyperemia, and pain (one patient) were the presenting symptoms. Microcatheter systems were used for catheterization. We used n-butyl cyanoacrylate mixture as the embolizing agent in all patients. Results: On angiograms the inferior gluteal artery (one patient), internal pudendal artery (one patient), perforating branch of the profundal femoral artery (six patients), superficial femoral artery (one patient), peroneal artery (two patients), and anterior tibial artery (one patient) were found to be injured. In all patients, the source of arterial bleeding could be reached, and a safe embolization was achieved. Nontarget embolization due to backflow of n-butyl cyanoacrylate mixture was detected in two patients and inguinal hematoma at the puncture site occurred in one patient. Conclusions: We conclude that embolization-particularly n-butyl cyanoacrylate embolization-is technically feasible in patients with penetrating peripheral arterial trauma.

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice. PMID:26619670

    A vapor block resistant liquid artery structure for heat pipes. A solid tube artery with openings is encased in the sintered material of a heat pipe wick. The openings are limited to that side of the artery which is most remote from the heat source. The liquid in the artery can thus exit the artery through the openings and wet the sintered sheath, but vapor generated at the heat source is unlikely to move around the solid wall of the artery and reverse its direction in order to penetrate the artery through the openings. An alternate embodiment uses finer pore size wick material to resist vapor entry.

    Distal anterior choroidal artery aneurysms are quite rare, and appropriate treatment timing and methods remain unclear. Direct surgery of these aneurysms is difficult due to their deep location, small size, and angioarchitecture;however, pseudoaneurysms might disappear spontaneously with conservative treatment. A 65-year-old man with a history of hypertension was admitted to our hospital with a 5-day history of sudden headache and nausea. Computed tomography revealed an intraventricular hematoma located mainly in the right lateral ventricle. Cerebral angiography 7 days after onset revealed a right distal anterior choroidal artery aneurysm and proximal right middle cerebral artery occlusion caused by atherosclerotic changes. Endovascular coil embolization was performed under general anesthesia 14 days after onset. Preoperative angiography demonstrated definite enlargement of the aneurysm and stasis of the contrast agent in the aneurysm in the venous phase. Detachable platinum coils were delivered into the aneurysm and parent artery. The patient was discharged neurologically intact after the procedure. Follow-up angiography 3 months after coil embolization showed complete occlusion of the aneurysm. In recent years, endovascular surgery has emerged as a less invasive treatment option. Early treatment should be considered for patients with ruptured distal anterior choroidal artery aneurysm because these aneurysms might grow and re-rupture in the short term.

    Vascular lesions of the shoulder may be misinterpreted as one of the more familiar shoulder abnormalities by a treating physician. We are reporting on 13 athletes who were found to have symptoms related to compression of the subclavian or axillary artery or their tributaries. Nine were amateur or professional baseball pitchers. Severe arm fatigue or finger ischemia, secondary to embolization, were presenting symptoms. Arm fatigue was noted in all pitchers. After complete history and physical examination, including auscultation for bruits in functional positions, all athletes were evaluated by noninvasive tests (Doppler and Duplex scanning). Arteriography was performed with positional testing, recreating overhead activity, and complete radiographic visualization of the dye to the digital arteries. Two patients were found to have subclavian artery aneurysm. The remaining athletes were found to have compression of the subclavian artery beneath the anterior scalene muscle (five patients), the axillary artery beneath the pectoralis minor (two patients), both arterial segments (two patients), and one was found to have arterial compromise at the level of the humeral head. Branch artery compression was also noted. One pitcher occluded the posterior circumflex humeral artery with embolization to the digit. The two patients with subclavian aneurysms underwent saphenous vein bypass with cervical rib resection. All of the other athletes except one underwent resection of a 2 to 3 cm segment of the anterior scalene muscle or pectoralis minor muscles. All returned to their previous level of activity except one patient who developed impingement type symptoms and required acromioplasty. He is currently undergoing rehabilitation. Proper recognition of vascular compromise in the upper extremity of athletes is essential to avoid the catastropic complications of arterial thrombosis.

    Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. Clinical presentation ranges from chest pain alone to ST-segment-elevation myocardial infarction, ventricular fibrillation, and sudden death. The treatment of patients with spontaneous coronary artery dissection is challenging because the disease pathophysiology is unclear, optimal treatment is unknown, and short- and long-term prognostic data are minimal. We report the case of a 70-year-old woman who presented with an acute ST-segment-elevation myocardial infarction secondary to a spontaneous dissection of the left anterior descending coronary artery. She was treated conservatively. Cardiac tamponade developed 16 hours after presentation. Repeat coronary angiography revealed extension of the dissection. Medical therapy was continued after the hemopericardium was aspirated. The patient remained asymptomatic 3 years after hospital discharge. To our knowledge, this is the first reported case of spontaneous coronary artery dissection in association with cardiac tamponade that was treated conservatively and had a successful outcome.

    Arteriopathy restricted to the popliteal artery, except in cases of atheroma, must indicate three of four unusual diagnoses: the trapped popliteal artery and the dessicating haematoma are anatomo-clinical entities that have been identified only relatively recently. The popliteal artery may be trapped by the medial gastrocnomius muscle, round the tendon of which the artery passes (totally or partially). This results in compression of the artery and eventually in thrombosis. Clinically, intermittent claudication is seen that may deteriorate and lead to gangrene of the toes. Arteriography makes it possible to diagnose the condition as the condition as the artery is considerably displaced inwards. Surgical correction is simple: sectioning of the tendon and repositioning of the artery. Dessicating haematoma of the popliteal artery is due essentially to atheroma, associated with medianecrosis. A "egg-timer" stenosis is found by arteriography and this condition also progresses towards thrombosis. Arterial restoration is called for, usually by bridging. PMID:1230799

    Acute traumatic aortic injury is a potentially lethal condition with most patients die at the scene of the accidents. Rapid deceleration due to motor vehicle accidents is the commonest mechanism of injury. These injuries can be successfully repaired in the few patients who survive the initial trauma if proper diagnosis and rapid treatment are provided. The occurrence of acute traumatic aortic injury in patients with congenital abnormality of the aortic arch has been rarely reported; however, it renders the diagnosis and treatment more difficult. In this paper, we describe an extremely rare case of aortic injury in a young patient who had a right sided aortic arch with rupture of an aberrant left subclavian artery. The patient was suspected to have a Kommerell’s diverticulum in the aberrant subclavian artery origin. This injury resulted in an unusually huge pseudoaneurysm involving part of the mediastinum and extending into the neck. Unfortunately; patient succumbed in spite of surgical intervention.

    Numerous civilian and military personnel are involved in SCUBA diving activities. In this day of rapid air travel it is important that all physicians, not just those living near the coast or dive centers, be familiar with the basics of diagnosing and treating diving-related injuries. One of the more serious complications of dysbarism is Arterial Gas Embolism (AGE). This case history involves an atypical presentation of delayed onset AGE in a military diver trainee, and its treatment. This article then reviews the incidence, etiology, pathophysiology, "classic" presentation and current treatment of this disease. Systemic pathophysiology secondary to the effects of intravascular air of AGE is also discussed.

    OBJECTIVES: Behcet’s disease is a form of systematic vasculitis that affects vessels of various sizes. Aortic pseudoaneurysm is one of the most important causes of death among patients with Behcet’s disease due to its high risk of rupture and associated mortality. Our study aimed to investigate the outcomes of Behcet’s disease patients with aortic pseudoaneurysms undergoing open surgery and endovascular aortic repair. METHODS: From January 2003 to September 2014, ten consecutive patients undergoing surgery for aortic pseudoaneurysm met the diagnostic criteria for Behcet’s disease. Endovascular repair was the preferred modality and open surgery was performed as an alternative. Systemic immunosuppressive medication was administered after Behcet’s disease was definitively diagnosed. RESULTS: Eight patients initially underwent endovascular repair and two patients initially underwent open surgery. The overall success rate was 90% and the only failed case involved the use of the chimney technique to reach a suprarenal location. The median follow-up duration was 23 months. There were 7 recurrences in 5 patients. The median interval between operation and recurrence was 13 months. No significant risk factors for recurrence were identified, but a difference in recurrence between treatment and non-treatment with preoperative immunosuppressive medication preoperatively was notable. Four aneurysm-related deaths occurred within the follow-up period. The overall 1-year, 3-year and 5-year survival rates were 80%, 64% and 48%, respectively. CONCLUSIONS: Both open surgery and endovascular repair are safe and effective for treating aortic pseudoaneurysm in Behcet’s disease patients. The results from our retrospective study indicated that immunosuppressive medication was essential to defer the occurrence and development of recurrent aneurysms. PMID:27438562

    An artery vapor trap. A heat pipe artery is constructed with an extension protruding from the evaporator end of the heat pipe beyond the active area of the evaporator. The vapor migrates into the artery extension because of gravity or liquid displacement, and cooling the extension condenses the vapor to liquid, thus preventing vapor lock in the working portion of the artery by removing vapor from within the active artery. The condensed liquid is then transported back to the evaporator by the capillary action of the artery extension itself or by wick located within the extension.

    Abstract Amyloidosis involves extravascular deposition of fibrillar proteins within tissues and organs. Primary light chain amyloidosis represents the most common form of systemic amyloidosis involving deposition of monoclonal immunoglobulin light chains. Although pulmonary amyloid deposition is common in primary amyloidosis, clinically significant pulmonary amyloidosis is uncommon, and elevated pulmonary artery pressures are rarely observed in the absence of other underlying etiologies for pulmonary hypertension, such as elevated filling pressures secondary to cardiac amyloid. In this case report, we present a patient with primary light chain amyloidosis and pulmonary arterial hypertension in the setting of pulmonary vascular and right ventricular myocardial amyloid deposition.

    External Iliac Artery Endofibrosis (EIAE) is an uncommon disease usually affecting young, otherwise healthy, patients. It usually involves cyclists but cases have been reported in other groups of endurance athletes. The external iliac artery is the most affected anatomical site but other locations are described too. The precise pathophysiology and long-term evolution of the disease still remain unknown. The diagnosis may be challenging and delayed as the patients usually present symptoms only in extreme conditions and physical and instrumental examinations may be normal at rest. We present two cases of young professional cyclists who suffered of exercise-induced leg pain which led them to reduce running. Both patients were firstly treated with balloon angioplasty that rapidly failed to improve their symptoms. The successive open surgery with endofibrosectomy and autologous saphenous vein closure patch completely resolved physical limitations. EIAE is a rare disease that can induce arterial stenosis, thrombosis, dissection and secondary atheroma. After-exercise ankle-brachial index represents a useful diagnostic criterion. Careful observation of angio-CT may strengthen the suspect. Knowledge of the these features allows a better pre-operative assessment and an early effective treatment. Surgical revascularization remains the gold standard approach. PMID:26888703

    Evidence from recent randomized controlled studies comparing intra-arterial (IA) therapy with intravenous tissue plasminogen activator highlighted the mismatch between recanalization success and clinical outcomes in patients presenting with acute ischemic stroke. There is emerging interest in the impact of arterial collateralization, as determined by leptomeningeal anastomoses (LMAs), on the treatment outcomes of IA therapy. The system of LMA constitutes the secondary network of cerebral collateral circulation apart from the Circle of Willis. Both anatomic and angiographic studies confirmed significant interindividual variability in LMA. This review aims to outline the current understanding of arterial collateralization and its impact on outcomes after IA therapy for acute ischemic stroke, underpinning the possible role of arterial collateralization assessment as a selection tool for patients most likely to benefit from IA therapy.

    Dolichoectasia is a medical term used to describe elongated and dilated vessels that follow a tortuous and windy course with frequent loops and curves. We are presenting the natural history in images of a normal basilar artery becoming dolichoectatic, followed by the formation of an aneurysm, over a period of many years, in 60-year-old Caucasian man with a long history of secondary progressive multiple sclerosis and uncontrolled arterial hypertension, who was diagnosed with dolichoectasia of basilar artery in 2008. Although relatively stable at this point, eventually his mobility deteriorated and signs from the cranial nerves, such as trigeminal neuralgia and bilateral palsy of the VI and the VII nerves were added in the clinical picture. In 2014, both computed tomography and magnetic resonance imaging of the brain revealed the formation of an unruptured aneurysm of the basilar artery.

A classic attack is the pallor of the distal extremity, followed by cyanosis and redness, accompanied by paresthesia, usually as heat. When it occurs without apparent cause is called primary Raynaud's phenomenon. When associated with other disease, is called secondary Raynaud's phenomenon. The secondary table is associated with increased frequency of rheumatic diseases of collagen. They can also present certain drugs that cause vasoconstriction, such as ergotamine, beta-adrenergic antagonists, contraception and sympathomimetic drugs. Regarding the latter, we present a case of Raynaud's phenomenon secondary to methylphenidate in a 14 years.

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

    A procedure for priming an arterial heat pump is reported; the procedure also has a means for maintaining the pump in a primed state. This concept utilizes a capillary driven jet pump to create the necessary suction to fill the artery. Basically, the jet pump consists of a venturi or nozzle-diffuser type constriction in the vapor passage. The throat of this venturi is connected to the artery. Thus vapor, gas, liquid, or a combination of the above is pumped continuously out of the artery. As a result, the artery is always filled with liquid and an adequate supply of working fluid is provided to the evaporator of the heat pipe.

    An improved heat pipe with an external artery. The longitudinal slot in the heat pipe wall which interconnects the heat pipe vapor space with the external artery is completely filled with sintered wick material and the wall of the external artery is also covered with sintered wick material. This added wick structure assures that the external artery will continue to feed liquid to the heat pipe evaporator even if a vapor bubble forms within and would otherwise block the liquid transport function of the external artery.

    Background Cochleovestibular symptoms, such as vertigo, tinnitus, and sudden deafness, are common manifestations of microvascular diseases. However, it is unclear whether these symptoms occurred preceding the diagnosis of peripheral artery occlusive disease (PAOD). Therefore, the aim of this case-control study was to investigate the risk of PAOD among patients with vertigo, tinnitus, and sudden deafness using a nationwide, population-based health claim database in Taiwan. Methods We identified 5,340 adult patients with PAOD diagnosed between January 1, 2006 and December 31, 2010 and 16,020 controls, frequency matched on age interval, sex, and year of index date, from the Taiwan National Health Insurance Research Database. Risks of PAOD in patients with vertigo, tinnitus, or sudden deafness were separately evaluated with multivariate logistic regression analyses. Results Of the 5,340 patients with PAOD, 12.7%, 6.7%, and 0.3% were diagnosed with vertigo, tinnitus, and sudden deafness, respectively. In the controls, 10.6%, 6.1%, and 0.3% were diagnosed with vertigo (P < 0.001), tinnitus (P = 0.161), and sudden deafness (P = 0.774), respectively. Results from the multivariate logistic regression analyses showed that the risk of PAOD was significantly increased in patients with vertigo (adjusted odds ratio = 1.12, P = 0.027) but not in those with tinnitus or sudden deafness. Conclusions A modest increase in the risk of PAOD was observed among Taiwanese patients with vertigo, after adjustment for comorbidities. PMID:27631630

    Dyslipidemias rank among the most important preventabile factors of atherogenesis and its progression. This topic is increasingly being discussed as e.g. more than 50% of Slovak population die on atherosclerotic complications. According to etiology we distinguish primary dyslipidemias with strictly genetic background and secondary ones with origin in other disease or pathological state. Secondary dyslipidemias accompany various diseases, from common (endocrinopathies, renal diseases etc) to rare ones (thesaurismosis etc.) and represents one of symptoms of these diseases. Apart from particular clinical follow up of diagnosed dysipidemias, basic screening and secondary causes as well as treatment due to updated guidelines is recuired. In this review we present the most frequent dyslipidemias of clinical practice.

    Canine pulmonary arterial hypertension (PAH) remains under-recognized and under-treated despite being prevalent. This retrospective study investigated whether selected historical and physical examination findings were associated with the diagnosis of canine PAH, defined as tricuspid regurgitation (TR) with a confirmed systolic pressure gradient ≥ 35 mm Hg. Two hundred and one client-owned dogs (PAH group, n=96; control group, n=105) were studied. Dogs in the control group had TR with a confirmed systolic gradient <35 mm Hg. All dogs underwent a complete physical examination and a complete echocardiographic assessment. A loud systolic right-apical murmur (RAM) was significantly associated with TR ≥ 35 mm Hg. The proportion of dogs with PAH significantly increased as the RAM grade increased, with odds ratios of 4.4-37.6 for Grades 3/6-5/6 (P=0.004 to <0.001), respectively. A stronger right-than-left apical-murmur had a positive predictive value (PPV) of 83% and was 96% specific for TR ≥ 35 mm Hg, and when combined with syncope, it had a PPV of 92% and was 92% specific. A Grade ≥ 4/6 RAM had a PPV of 85% and was 93% specific. Syncope with a Grade ≥ 4/6 RAM had a PPV of 94% and was 92% specific. Ascites combined with a Grade ≥ 4 or ≥ 5/6 RAM had a PPV of 100% and was 100% specific for TR ≥ 35 mm Hg. For each of these three murmur categories (Grades ≥ 4/6, ≥ 5/6, and a louder-right-than-left murmur), when detected with no concurrent ascites or syncope, the positive likelihood ratio varied from 4.6 to 6.4. A loud systolic RAM in dogs with degenerative valve disease is highly suggestive of concurrent PAH.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Characteristics of brain evoked activity were studied in patients with most frequent variants of secondary headaches: chronic posttraumatic headaches, cervicogenic headaches and vascular headaches in patients with arterial hypertension and chronic brain ischemia. The multimodal registration of evoked potentials (EP) (short-latency brainstem auditory, visual EPs to flash stimulation and cognitive EPs - P300) revealed signs of brainstem dysfunction, decrease of visual analyzer and diminished cognitive functions in most patients with secondary headaches. Based on results obtained, we can recommend a complex therapy of chronic secondary headaches with neuroprotectors and nootropics.

    Secondary osteoporosis is less common than primary osteoporosis. It may be suspected in patients who present with a fragility fracture despite having no risk factors for osteoporosis. In addition, secondary osteoporosis should be considered if the bone density Z-score is -2.5 or less. Consider the fracture site and presence of other clinical clues to guide investigations for an underlying cause. The tests to use are those that are indicated for the suspected cause. Baseline investigations include tests for bone and mineral metabolism (calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone), liver and kidney function, full blood count and thyroid-stimulating hormone. More detailed testing may be required in patients with severe osteoporosis.

    Superior mesenteric artery syndrome is a rare and controversial form of upper intestinal obstruction in which the third part of the duodenum is compressed by the overlying superior mesenteric artery. Any disease process decreasing the angle between the superior mesenteric artery and the abdominal aorta can result in the external compression of the duodenum and subsequent intestinal obstruction. The aetiology, presentation, investigation and management of this unusual condition are discussed. PMID:9497945

    Trapped popliteal artery syndrome is relatively uncommon: the literature reports some 60 cases. The clinical picture is linked to compression of the popliteal artery by the gastrocnemius as it contracts, thus distorting the arterial route. The result is an interruption in the blood flow distally to the area involved due to stenosis of the blood vessel that is at first functional but becomes organic. PMID:3808379

    In giant cell arteritis (GCA), involvement of the vertebral arteries is rare with reported rates of 3%-4% for ischemic events secondary to vertebral artery stenosis or occlusion for those patients with GCA. This case study describes a patient who initially presented with acute onset of vertigo but was also found to have transient, side-alternating upper limb neurological findings. While initial imaging showed no vascular abnormalities, it was not until GCA was eventually confirmed with a temporal artery biopsy that the initial scans were shown to have bilateral narrowing of the vertebral arteries. While rare, vertebral artery involvement is an important complication to consider in the setting of GCA due to the high rate of associated mortality, despite immunosuppressive therapy. PMID:27279753

    2015-04-21

    Arteries can become tortuous in response to abnormal growth stimuli, genetic defects and aging. It is suggested that a buckling instability is a mechanism that might lead to artery tortuosity. Here, the buckling instability in arteries is studied by examining asymmetric modes of bifurcation of two-layer cylindrical structures that are residually stressed. These structures are loaded by an axial force, internal pressure and have nonlinear, anisotropic, hyperelastic responses to stresses. Strain-softening and reduced opening angle are shown to lower the critical internal pressure leading to buckling. In addition, the ratio of the media thickness to the adventitia thickness is shown to have a dramatic impact on arterial instability.

    Hypertension remains the most common reason for patients to visit physicians in the United States. Although awareness of hypertension among patients continues to increase, adequate control of hypertension remains poor. In addition, as the population of patients with hypertension ages, atherosclerosis becomes increasingly prevalent. Atherosclerotic renal artery stenosis is the most common secondary cause of hypertension and can cause hypertension to be difficult to control. Atherosclerotic renal artery stenosis may also result in chronic renal insufficiency. The physician must be aware of the clinical scenarios in which renal artery stenosis may occur, methods of diagnosis, and indications for intervention.

  19. The middle suprarenal artery arising from the superior mesenteric artery.

    2012-01-01

    We observed a rare case of the middle suprarenal artery branching out from the superior mesenteric artery in a 78-year-old male. This atypical artery enters the right suprarenal gland that was also supplied by the superior and the inferior suprarenal arteries as usual. In embryonic stages, vasculature of the vitelline system and the gonadal system is differentially organized. The superior mesenteric artery has been generally thought to be pure vitelline, since there has been no evidence that the superior mesenteric artery supplies other organs than digestive. We then speculate that the present middle suprarenal artery is a remnant of the embryonic gonadal artery from the superior mesenteric artery, whereas a stem artery to the testis disappeared. Surgeons should take notice of the middle suprarenal artery when operations are conducted around the superior mesenteric artery.

    Idiopathic dilatation of the pulmonary artery (IDPA) is a rare congenital heart disease. It has been described for almost one hundred years, and numerous definitions have been proposed. The IDPA diagnostic criteria have not been updated for years. Secondary to primary disease, pulmonary artery aneurism was recognised as a lethal defect; however, long-term follow-up of patients with IDPA has not been well researched. Thus, indications to medical or surgical treatment are not evidence based. Here, we present a rare case of a 54-year-old patient with IDPA, who remained under observation for 36 years without surgical intervention. PMID:26855651

    Although thrombus formation following myocardial infarction in adults is well known, intracardiac thrombosis in children is uncommon. We report the case of a large left ventricular thrombus in an infant with ischemic cardiomyopathy secondary to anomalous origin of the left coronary artery from the pulmonary artery. Given its mobility and protrusion across the aortic valve, the patient underwent urgent thrombus removal through a transaortic approach. There were no embolic or neurologic complications. This case highlights that thrombectomy may be performed safely and successfully in critically ill pediatric patients.

    A 24-year-old male patient was the victim of a firearm wound that penetrated the thorax. He arrived at another hospital hemodynamically unstable and was submitted to exploratory surgery by means of bithoracotomy. A lesion of the left branch of the pulmonary artery was detected and successfully repaired. He was submitted for computer-aided tomography on the fifth postoperative day, and a lesion of the mid-thoracic aorta was detected, which formed a saccular image. Considering that the patient had already been submitted to a bithoracotomy and that a direct approach to repair would involve another thoracotomy within a short period of time, endovascular treatment was chosen in our hospital. The procedure was performed under fluoroscopy. A second computer-aided tomography indicated adequate treatment of the lesion, with no indication of an endoleak. He has undergone ambulatory follow-up for 36 months without any problem related to the procedure. While endovascular treatment of the aorta has developed enormously, multicenter studies are needed to better define the long-term results of this approach.

    Transposition of the great artery is one of common congenital cardiac disease resulting cyanosis. Death occurs easily in untreated patients with transposition and intact ventricular septal defect (VSD) in infancy at a few days of age when posterior descending coronary artery (PDA) closed. Since there are 2 parallel circulations, flow from pulmonary to systemic circulation is necessary for systemic oxygenation, and Balloon atrial septostomy or prostaglandin infusion should be performed especially if patient do not have VSD. Although the advent of fetal echocardiography, it is difficult to diagnose the transposition of the great arteries (TGA) as abnormality of great vessels is relatively undistinguishable. The diagnosis of transposition is in itself an indication for surgery, and arterial switch procedure is performed in the case the left ventricle pressure remains more than 2/3 of systemic pressure. Preoperative diagnosis is important as associated anomalies and coronary artery branching patterns are important to decide the operative indication and timing of surgery.

    Prinzmetal’s variant angina describes chest pain secondary to reversible coronary artery vasospasm in the context of both diseased and non-diseased coronary arteries. Symptoms typically occur when the patient is at rest and are associated with transient ST-segment elevation. Acute episodes respond to glyceryl trinitrate, but myocardial infarction and other potentially fatal complications can occur, and long-term management can be challenging. Although it is not well understood, the underlying mechanism appears to involve a combination of endothelial damage and vasoactive mediators. In this case, a 35-year-old woman with myocardial infarction secondary to coronary artery vasospasm experienced recurrent chest pain. Coronary angiography revealed severe focal stenosis in the mid left anterior descending artery, which completely resolved after administration of intracoronary glyceryl trinitrate. The patient was discharged on nitrates and calcium channel blockers. The patient re-presented with another myocardial infarction, requiring up-titration of medical therapy. PMID:26034323

To minimize the risk of impotence in this young patient, successive selective embolizations with autologous blood clot were performed to close the fistulas. This led to an uncomplicated full recovery. No fistula was detectable on Doppler ultrasonography at 1-year follow-up. Review of the literature confirms the safety of embolization with autologous clot.

    PurposeTo evaluate the usefulness of an approach through the radial artery distal to the arteriovenous anastomosis for salvaging nonmaturing radiocephalic arteriovenous fistulas.MethodsProcedures that fulfilled the following criteria were retrospectively reviewed: (1) autogenous radiocephalic fistulas, (2) fistulas less than 3 months old, (3) distal radial artery approach for salvage. From 2005 to 2011, a total of 51 patients fulfilling the above criteria were enrolled. Outcome variables were obtained from angiographic, clinical and hemodialysis records, including the success, complication, and primary and secondary patency rates.ResultsThe overall anatomical and clinical success rates for the distal radial artery approach were 96 and 94 %, respectively. The average procedure time was 36 {+-} 19 min. Six patients (12 %) experienced minor complications as a result of extravasations. No arterial complication or puncture site complication was noted. The postinterventional 6-month primary patency rate was 51 %, and the 6-month secondary patency rate was 90 %. When the patients were divided into a stenosed group (20 patients) and an occluded group (31 patients), there were no differences in the success rate, complication rate, or primary and secondary patency rates.ConclusionAn approach through the radial artery distal to the arteriovenous anastomosis is an effective and safe alternative for the salvage of nonmaturing radiocephalic arteriovenous fistulas, even for occluded fistulas.

    The purpose of this study was to evaluate clinical results and technical problems of transcatheter coil embolization for splenic artery aneurysm. Subjects were 16 patients (8 men, 8 women; age range, 40-80 years) who underwent transcatheter embolization for splenic artery aneurysm (14 true aneurysms, 2 false aneurysms) at one of our hospitals during the period January 1997 through July 2005. Two aneurysms (12.5%) were diagnosed at the time of rupture. Multiple splenic aneurysms were found in seven patients. Aneurysms were classified by site as proximal (or strictly ostial) (n = 3), middle (n = 3), or hilar (n = 10). The indication for transcatheter arterial embolization was a false or true aneurysm 20 mm in diameter. Embolic materials were fibered coils and interlocking detachable coils. Embolization was performed by the isolation technique, the packing technique, or both. Technically, all aneurysms were devascularized without severe complications. Embolized aneurysms were 6-40 mm in diameter (mean, 25 mm). Overall, the primary technical success rate was 88% (14 of 16 patients). In the remaining 2 patients (12.5%), partial recanalization occurred, and re-embolization was performed. The secondary technical success rate was 100%. Seven (44%) of the 16 study patients suffered partial splenic infarction. Intrasplenic branching originating from the aneurysm was observed in five patients. We conclude that transcatheter coil embolization should be the initial treatment of choice for splenic artery aneurysm.
