The other reports a case of fibrodysplasic aneurysm of the extracranial internal carotid artery that was successfully treated by resection and direct end-to-end anastomosis of the internal carotid artery.

Marfan’s syndrome is an autosomal dominant disorder of connective tissue characterized by a large number of possible mutations and by heterogeneity of clinical presentation primarily in skeletal, ocular and cardiovascular organ systems. Cardiovascular complications of the disease are responsible for high mortality. The case of a 42-year-old patient with a progressive advanced abdominal aorta dilatation visualized on computed tomography images is presented. Pathogenesis, diagnosis and management of patients with Marfan’s syndrome are also discussed.

Subject: Supraaortic angioplasty is often not feasible in patients with Takayasu's arteritis because of involvement of long segment of arteries. Consequently, the role of surgical treatment in the management of cerebral ischemia is important in this disease. The objective of this work is to specify the indications and surgical techniques in lesions of arteries to the head in this disease and to report our experience., Methods: Seven patients with cervical arterial lesions due to Takayasu's arteritis were treated by bypass surgery in the department of vascular surgery, Ibn-Sina hospital on one period of 11 years., Results: It is about 6 women and one man of middle age at the time of the diagnosis of 33,8 years. The revealing signs were essentially of neurological and ocular order. Six of our patients were in inflammatory thrust at the time of the diagnosis, and required a medical treatment first to basis of corticosteroids. Bypasses from the ascending aorta to the carotid artery were performed in six cases. In one case, the bypass was performed between the brachiocephalic artery and common carotid artery. A death in relation with a cerebral hemorrhage occurred 2 days after the revascularisation. A clean improvement of the functional signs was noted among 3 patients, whereas the improvement was partial at two other. A secondary thrombosis of the bypass surgery occurred in 3 cases., Conclusion: The natural history of Takayasu's arteritis and its evolution is badly known. The operative indications must not rest solely on the only anatomical balance, but based on a bundle of arguments in which, the assessment of the cerebral blood flow would be useful. Cerebral hyperperfusion syndrom constitutes a major risk that can be reduced by staged revascularisations.

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.

Extracranial carotid aneurysms caused by Takayasu's arteritis is extremely rare. Their evolutionary risk is dominated by rupture and cerebral ischemia. We report a case of a 23 years old woman presenting bilateral common carotid aneurysm secondary to Takayasu's arteritis. Surgical treatment with the patient under steroid coverage was performed to prevent the risque of rupture. The aneurysm was resected, reconstruction was performed with prothetic aortocarotid bypass. She was discharged without major complications. The graft have remanied patent during the four years follow-up periods. A biologic inflammatory syndrome and a parietal thickening of the aneurysm in a young woman must provoke diagnosis. The surgery must be appropriate every time that the diagnosis is carried considering the evolutionary risk of these aneurysms.

The malignant tumors of the inferior vena cava are rare. Their prognosis is bad. We report two cases of a 17-year-old and 46-year-old woman presenting the one an intimal sarcoma of the inferior vena cava and the other a metastatic of adenocarcinoma whose primary tumor was not identified. The aortic wall was invaded in both patients. The ureter repulsed in first case, was invaded in second case. The treatment consisted on resection of the tumor including the aortic wall with vein closure in both patients, with right nephrectomy in second patient. In the two cases, a prosthetic reconstruction of the arterial integrity was attempted with aortobiiliac bypass. The two patients died after relapse tumorous to the 6th month in first patient and by multisystem organ failure 5th day post-operative in second. Through these two personal cases, we try to point out the difficult problem of diagnosis that put these tumors and their bad prognosis despite an improvement of treatment.
