Giant abdominal aortic aneurysm of uncommon etiology due to Behçet disease

Abstract Behcet disease is a multisystem disorder presenting with recurrent oral and genital ulcerations as well as with ocular involvement. Vascular involvement can occur in up to 50% of affected patients. Arterial aneurysms are often multiple and are characterized by a saccular configuration with increased risk of unexpected rupture, thrombosis, and aneurysm recurrence. Here we report a case of giant infrarenal abdominal aortic aneurysm in a 34-year-old man with Behcet disease who underwent aneurysmorrhaphy and aortobifemoral bypass.
