False Aneurysm of the Popliteal Artery Complicated by a Deep Venous Thrombosis Revealing an Exostosis in a 20-Year-Old Woman.

Exostoses or osteochondromas are benign osseous tumors that develop on the bone surface and can be sporadic or hereditary. Their evolution is generally benign, but they may be complicated in some patients by conflicts with the surrounding nervous or vascular structures, in particular arteries. We report a case of false aneurysm of the popliteal artery secondary to an isolated exostosis of the left femur in a 20-year-old woman. A delay in the diagnosis allowed the development of the false aneurysm, which was at the origin of a major venous compression. The surgical treatment consisted in aneurysmectomy and reconstruction by end-to-end anastomosis associated with the resection of the osseous tumor, and the deep venous thrombosis was treated medically.

Infectious aneurysm of the two primary iliac arteries: rare localization of Salmonella typhimurium infection.

Infectious aneurysm is a severe entity of the aneurysmal pathology, due essentially to a bacterial agent. The most frequently implicated organisms are salmonella and staphylococci. We report the case of an infectious aneurysm of the two primitive iliac arteries with Salmonella typhimurium in a 70-year-old man.

Double localization of a non-anastomotic pseudoaneurysm after an axillofemoral bypass: a case report and review of the literature.

BACKGROUND: A traumatic non-anastomotic pseudoaneurysm is a rare complication of an axillofemoral bypass graft. Fewer than 20 cases have been reported in the literature. Our case is unusual in that we report a double localization of this complication. CASE PRESENTATION: We report the case of a 60-year-old Arabic male patient who was diagnosed with two hematomas in the trajectory of his axillofemoral bypass secondary to a traumatism. The diagnosis of a non-anastomotic pseudoaneurysm was retained considering the results of a computed tomography angiography scan, which showed the double localization of the pseudoaneurysm. Surgical management consisted of flattening the pseudoaneurysm along with the interposition of a prosthetic segment. There were no postoperative complications and our patient was well 3 years after discharge. CONCLUSIONS: Non-anastomotic pseudoaneurysm is a rarely described complication of a axillofemoral bypass graft. To the best of our knowledge, a double localization has not been described in the literature before. Minimally invasive techniques as a treatment option are being widely used as an alternative to open repair.

True Aneurysm of the Left Internal Thoracic Artery.

Aneurysms of the internal thoracic artery (ITA) are rare and can have many etiologies. Hyperflow is an exceptional etiology. We report the case of a 56-year-old woman who presented with a stress-induced ischemia of the left arm. Computed tomography angiography showed occlusion of the subclavian artery and a true aneurysm of the ITA. The ITA aneurysm was resected without restoration of the ITA continuity and a carotid-subclavian bypass was performed. Pathological examination of the aneurysm sac was not specific.

A Rare Case of a Massive Carotid Body Tumor in a 3-Year-Old Infant: Case Presentation and a Literature Review.

BACKGROUND: Paragangliomas are neuroendocrine tumors derived from the extra-adrenal paraganglia of the autonomic nervous system. Only 3% of all paragangliomas are reported to occur in the head and neck region. The most common paraganglioma of the head and neck is the carotid body tumor. Only few cases have been described in the literature regarding the pediatric age group less than aged 14 years, mostly as case reports. CASE REPORT: Our case describes a massive paraganglioma in the head and neck region occurring in a 3-year-old Arabic boy, for which surgical excision was not possible and radiotherapy resulted in a good clinical and radiologic response. CONCLUSIONS: Paragangliomas a rare in children and mostly diagnosed in a locally advanced stage. Surgery in most cases is difficult especially because of the proximity of the vessels; radiotherapy is still a good alternative for those cases.

Venous thromboembolism in cancer patients: an underestimated major health problem.

Venous thromboembolism (VTE) is a major health problem among patients with cancer, its incidence in this particular population is widely increasing. Although VTE is associated with high rates of mortality and morbidity in cancer patients, its severity is still underestimated by many oncologists. Thromboprophylaxis of VTE now considered as a standard of care is still not prescribed in many institutions; the appropriate treatment of an established VTE is not yet well known by many physicians and nurses in the cancer field. Patients are also not well informed about VTE and its consequences. Many studies and meta-analyses have addressed this question so have many guidelines that dedicated a whole chapter to clarify and expose different treatment strategies adapted to this particular population. There is a general belief that the prevention and treatment of VTE cannot be optimized without a complete awareness by oncologists and patients. The aim of this article is to make VTE a more clear and understood subject.

Successful endovascular management of postoperative arterio portal fistula.

Arterioportal fistulas are rare and mostly a result of late complication of gastric and biliary surgery. Surgical excision has been the therapy of reference. Endovascular treatment is emerging as a real alternative to surgery. The present study reports a case of postsurgical arterioportal fistula involving the gastroduodenal artery, the cause of portal hypertension, which was successfully treated by transarterial embolization using embospheres. Portal hypertension improved dramatically.

Ruptured tuberculous false aneurysm of the abdominal aorta: a case report.

Tuberculous false aneurysm of the aorta is rare and has an unpredictable complication of aneurysm rupture. We report a case of a 32-year old woman who was referred to the Department of Vascular Surgery, Avicenne Hospital for severe abdominal pain. Chest x-ray revealed miliary tuberculosis. Contrast enhanced computed tomography (CT) scan showed a false aortic aneurysm involving the juxtarenal aorta. Antituberculous treatment was started because of high presumption of tuberculosis. Five days later, the patient presented with symptoms of aneurysm rupture. She underwent an emergency a surgical resection of the aneurysm with repair of the aortic wall defect by a Dacron Silver patch. The histopathologic examination of the aortic wall showed features of tuberculosis.

Tuberculosis of the renal artery: a rare cause of renovascular arterial hypertension.

Tuberculosis is an endemic disease in Morocco. Main blood vessels are rarely affected; the few mentioned cases are aneurysmal. We report a 17-year-old patient presenting with renovascular arterial hypertension, revealed thanks to the discovery of an occlusion of the right renal artery in Duplex scan. During the intervention, the observation of pararenal and mesenteric tuberculous polyadenopathy let us suggest the same kind of lesion at the level of the occluded renal artery. Once antituberculosis treatment had been carried out, the right renal artery was revascularized with a right iliorenal bypass using reversed internal saphenous vein. The postoperative course was uneventful, with an 18-month follow-up. Arterial pressure was normal without antihypertensive treatment, and the bypass was patent. As far as we know, this is the first case of renovascular arterial hypertension resulting from tuberculosis treated with an iliorenal bypass.

Bilateral mycotic aneurysm of the superior gluteal artery.

Gluteal artery aneurysms are rare and mostly secondary to blunt or penetrating trauma. As an absolute rarity, we report an exceptional presentation of bilateral mycotic aneurysm of the superior gluteal artery in a 16-year-old boy associated with bacterial endocarditis. The left pseudoaneurysm was ruptured and treated using open surgery; 1 week later, the right location was successfully treated by embolization.

[Hepatic artery aneurysm]. / Anévrisme de l'artère hépatique.

INTRODUCTION: Aneurysms of the hepatic artery are relatively rare. Diagnosis often occurs only after rupture, and mortality is substantial. We report two new cases. CASES: The first patient was a 70-year-old woman whose asymptomatic aneurysm of the common hepatic artery was identified during ultrasound for vomiting and abdominal pain. Open aneurysm repair and a hepatosplenic bypass led to a favorable outcome. The second patient was a 54-year-old man; his right hepatic artery aneurysm was diagnosed after it ruptured in the gall bladder. DISCUSSION: We review the literature about hepatic artery aneurysms and discuss the clinical features and methods for diagnosis and treatment of these uncommon lesions.

Extracranial carotid aneurysm in Behçet disease: Report of two new cases.

Extracranial carotid aneurysm due to Behçet disease is extremely rare. To our knowledge, this complication has been previously reported in only 12 cases. We report two new cases of extracranial carotid aneurysm in Behçet disease and discuss the clinical features, therapeutic modalities, and postoperative complications of these uncommon lesions.
