[A case of aortoenteric fistula with iliac embolization].

A sixty-eight year-old woman complained of acute hematemesis and numbness of the right lower extremity. Physiocal examination on amission demonstrated revealed a pulsating mass in the midabdomen, absence of pulsation of the right femoral artery and cold pale skin of the right leg. The diagnosis of abdominal aneurysm with aortoenteric fistula and embolization embolectomy to the right iliac artery was mode by computed tomography although the fistula was not clearly visualized. The abdominal aneurysm was replaced with a Y-graft after embolectomy and the fistula to the duodenum was completely closed. Early diagnosis and emergency surgery are necessary to save the patient with this rare disease.
