Aneurysms of the iliac artery mostly occur in association with abdominal aortic aneurysms, and isolated occurrence of such aneurysm is uncommon. Recently we experienced three cases of isolated iliac artery aneurysm successfully treated by graft replacement.
Case 1: A 70-year-old man was seen at the hospital because of pulsative tumors in the bilateral thighs. Angiography revealed aneurysms in the bilateral common iliac arteries and internal iliac arteries involved in the bilateral femoral arteries. Case 2: A 70-year-old man was seen at the hospital because of a lower abdominal pain. Abdominal CT and angiography revealed aneurysms in the bilateral common iliac arteries. Case 3: An 81-year-old man was seen at the hospital because of intermittent claudication. Abdominal CT and angiography showed aneurysms in the bilateral internal iliac arteries. In case 1 and 2 graft replacement was performed, and the aneurysms in the bilateral internal iliac arteries in case 1 were kept intact. In case 3 aneurysmectomy was performed after ligation of the distal and proximal arteries of the aneurysm. All patients had uneventful postoperative course. We emphasize that early elective excision and grafting of the defect are desirable if the general condition of the patient permits, because isolated iliac aneurysms are often asymptomatic and fatal once ruptured.
