[Multiple aortic and femoral aneurysms: Unusual revelation of Behçet's disease]. / Multiples anévrismes aortiques et fémoral : mode de révélation inhabituel de la maladie de Behçet.

Arterial involvement in Behçet's disease is rare, the aortic localization is one of the most severe manifestations of the disease. We present an exceptional case of Behçet's disease revealed by two infrarenal abdominal aorta aneurysms, associated to a femoral artery pseudoaneurysm. The management of aneurysms in Behçet's disease is delicate, and requires the combination of surgical treatment with adjuvant medical drug therapy in order to reduce complications risk.

[Giant ruptured common femoral artery aneurysm revealing Behçet's disease]. / Rupture d'anévrisme géant de l'artère fémorale commune révélant une maladie de Behçet.

Vascular involvement in Behçet's disease is rare. Aneurysmal arterial involvement is the severe form of the disease, it constitutes a therapeutic challenge given its severity, and frequent secondary complications, especially at anastomosis. The systematic immunosuppressive drug treatment and surgical technique thoroughness can reduce relapse rate. We report the case of a young man in whom a ruptured false aneurysm of the common femoral artery revealed Behçet's disease. He underwent an open repair, with prosthetic arterial reconstruction, and anastomosis reinforcement with teflon.

[Painful cervical mass revealing an aneurysm of the internal jugular vein]. / Masse cervicale douloureuse révélant un anévrysme de la veine jugulaire interne.

Internal jugular vein aneurysms or phlebectasia of the internal jugular vein are considered a benign pathology. They are more and more diagnosed with the evolution of imaging techniques : ultrasonography, angioscanner and MRI. Clinically they are often by chance, however accompanying clinical signs can be seen such as pain, hoarseness or vocal cord paralysis. Several differential diagnoses can be mentioned such as laryngocoele, gill cyst, paraganglioma and hemangioma. They are of unknown etiology with several hypotheses on the etiopathogenesis and on the frequent localization on the right. Conservative treatment can be chosen for small aneurysms and in children. Surgical treatment finds its indication especially in the event of a complication such as thrombosis or for an aesthetic interest; other treatments such as endovascular treatment are being evaluated. We report the case of a 67-year-old woman admitted for a painful latero-cervical mass, and in whom the diagnosis of an aneurysm of the internal jugular vein was suspected and confirmed by ultrasound and CTscan. The patient received successful surgical treatment.

[Occlusion of the abdominal aorta in patients infected with the human immunodeficiency virus: Clinical case and review of the literature]. / Occlusion de l'aorte abdominale chez les patients infectés par le virus de l'immunodéficience humaine : cas clinique et revue de littérature.

HIV infection has now become a chronic disease with a good life expectancy thanks to antiretrovirals. The mortality currently is attributed to other pathologies in particular cardiovascular because of the inflammation and the side effects of the drugs. All arteries can be damaged in HIV, especially the aorta, with several types of lesions which can be occlusive, aneurysmal, dissecting, even with the cases of arteriovenous fistula which have been described. HIV occlusive arterial disease is different from atheromatous disease in HIV-free patients and this is confirmed by pathology and ultrasound studies, which makes it more difficult to manage HIV-related occlusions. The open surgical treatment especially in the acute forms is disappointing with complications of rethrombosis and infectious and of sepsis of prosthesis considering the immunosuppression, the endovascular treatment begins to become the treatment of choice in the aneurysmal pathology and probably it would be in the future for occlusive disease.

[Isolated atrial septal aneurysm: Exceptional cause of digital ischemia - a case report]. / Anévrysme isolé du septum interauriculaire : cause exceptionnelle d'ischémie digitale.

An atrial septal aneurysm (ASA) is a rare but well recognized entity characterized by saccular deformity of the atrial septum that bulges into the right or left atrium. Diagnosis can be established using transthoracic and transesophageal echocardiography. Although this abnormality is considered clinically benign, it has been independently associated with systemic or cerebral embolism. We present a unique case of isolated atrial septal aneurysm complicated by digital ischemia in a 51 years old woman.

[Acute lower limb ischemia revealing a paraneoplastic floating aortic thrombus]. / Ischémie aiguë de membre inférieur, révélant un thrombus aortique flottant paranéoplasique.

The floating mural thrombus of abdominal aorta is a rare and serious pathology detected as cause of peripheral and visceral embolism. Isolated aortic mural thrombosis is an unusual pathology occurring in an apparently normal aorta. A thorough search of embolic source must be initiated. Therapeutic management is based on systemic anticoagulation with the use of surgical approach in some cases.

[False aneurysm of the abdominal aorta revealing Behçet's disease]. / Faux anévrisme de l'aorte abdominale sous-rénale révélant une maladie de Behçet.

Behçet's disease (BD) is a systemic vasculitis diagnosed on the basis of clinical criteria established by the International Study Group for Behçet's. Vascular involvement is common, affecting both arteries and veins. Aortic localizations are rare and severe and can be life-threatening in case of rupture. Thrombosis is observed but aneurysm or false aneurysm are more common. Computed tomographic angiography is essential for diagnosis and study of the characteristics of aneurysms and false aneurysms. Treatment relies on corticosteroids and immunosuppressive drugs in severe forms supplemented by open or endovascular repair. This latter approach represents a safe and efficient alternative to open surgery, it induces fewer pseudoaneurysms and increases the survival rate especially in association with immunosuppressors. We report a case of Behçet disease revealed by a false aneurysm of the abdominal aorta treated by deployment of a covered stent.
