Behçet's syndrome, a multisystem disorder, is characterized by recurrent oral and genital aphthous ulcerations, eye lesions, and skin changes. Other manifestations, although rare, may affect the nervous, gastrointestinal, or loco- motor system, as well as veins and arteries. Vascular lesions occur in approxi mately 30% of reported cases. Although thrombosis in the larger veins is frequent, arterial thrombosis is somewhat less likely to occur. Only a few cases of arterial aneurysm have been documented in the literature.
This report describes a patient who had suffered from Behçet's syndrome for fifteen years and in whom a complete obstruction of the inferior vena cava was demonstrated. An aortailiac bypass was performed successfully, and the patient had had a good clinical recovery at long-term follow-up.
