Abstract
A 65-year-old man was referred to our service complaining of intermittent claudication of his left leg. During preoperative examinations, he was found to have bilateral isolated internal iliac artery aneurysms. As it was strongly suspected that ischemic colitis or gluteal ischemia would be caused if his bilateral internal iliac arteries were ligated during aneurysm surgery, his right internal iliac artery was reconstructed using a prosthetic graft. His postoperative course was uneventful. As aneurysm of the internal iliac artery is rare, there are few reports about reconstruction of the internal iliac artery. Technical details and pitfalls of internal iliac artery aneurysm surgery were discussed.
