[False aneurysm of the external iliac artery revealing Behçet's disease]. / Faux anévrysme de l'artère iliaque externe révélant une maladie de Behçet.

Behçet's disease is a vasculitis of unknown etiology. Vascular involvement is rare, but may be inaugural in many cases. We report a case of Behçet's disease revealed by a symptomatic pseudo-aneurysm of the external iliac artery. The symptomatology was non-specific. Ultrasound Doppler and computed tomographic angiography were essential for diagnosis. The pseudo-aneurysm was managed by endovascular treatment. Corticosteroid and immunosuppressant therapy were administrated after surgery.

[False aneurysm of the carotid artery revealing Behçet disease]. / Faux anévrysme de l'artère carotide révélant une maladie de Behçet.

Vascular involvement in Behçet's disease often present as venous thrombosis. Arterial damage is rare. We report a case of Behçet's disease occurring in a 40-year-old woman revealed by a false aneurysm of the left common carotid artery. The intervention consisted in a prosthetic graft after endovascular control. After a 2-year follow-up period, the patient did not develop any postoperative complication.

[Bilateral carotid aneurysm revealing Takayasu disease]. / Anévrisme carotidien bilatéral révélant une maladie de Takayasu.

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.
