A CASE REPORT OF ISOLATED SACCULAR BILATERAL COMMON AND INTERNAL ILIAC ARTERY ANEURYSMS ASSOCIATED WITH DISSECTING AORTIC ANEURYSM

Abstract

An insolated iliac artery aneurysm is a rare vascular disease for which surgical treatment should be considered, because the prognosis is extremely poor once rupture occurs. We report a case of isolated bilateral common iliac and internal iliac artery aneurysms associated with a DeBakey IIIb type dissecting aortic aneurysm.
A 75 year-old male deveroped severe back pain 2 years prior to admission. He was admitted to our hospital complaining of a right lower abdominal mass. The pulsatile mass was suspected of being a right common iliac artery aneurysm, and a left common iliac artery aneurysm was also detected by arteriography. The patient underwent arterial replacement using a Y-shaped Dacron graft with a left extra-peritoneal approach. The internal iliac artery was also reconstructed with a straight Dacron graft since internal iliac artery aneurysms were found during the procedure.
Isolated iliac artery aneurysms have a high protential for rupturing as compared to abdominal aortic aneurysms. Therefore surgical intervention is strongly recommended.
