[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.
