Operative management of bilateral internal iliac artery aneurysms.

A case of bilateral internal iliac artery aneurysms in association with an infrarenal abdominal aortic aneurysm is presented. The implications of surgical repair of these lesions are considered, particularly with reference to interruption of pelvic blood flow. Reimplantation of the inferior mesenteric artery is recommended when internal iliac artery flow is compromised during aortic reconstruction.
