Successful Repair of a Ruptured Common Iliac Aneurysm with Associated Arteriovenous Fistula Using Aneurysm Wall

Ruptured abdominal aortic aneurysms and common iliac artery aneurysms (CIAAs) are rarely associated with an arteriovenous fistula (AVF). In such cases, surgery is frequently extremely difficult and the prognosis is usually poor. We report a case of a ruptured CIAA with a common iliac AVF in a 58-year-old male patient who presented with symptoms of severe edema in his left lower extremity. We used an aneurysm wall patch to repair the fistula and successfully reconstruct the common iliac vein, and a bifurcated prosthetic graft for abdominal aortic and iliac artery replacement.
