[Giant ruptured common femoral artery aneurysm revealing Behçet's disease].

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.
