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.

Early experience with a new PTFE graft below the inguinal ligament.

Between July 1984 and July 1985, 65 expanded polytetrafluoroethylene grafts (Vitagraft) were implanted in the infrainguinal position in 51 patients, including 41 men and 10 women, with an average age of 63 years. The indications for surgery were severe claudication (36 grafts) or ischemic necrosis of the extremities (29 grafts). Thirteen of the patients (25%) had had a previously placed infrainguinal graft of another type that had failed, requiring reoperation.
