Long-Term Results of Endovascular Aneurysm Repair with Aortouni-iliac Custom-Made Stent Grafts

Abstract

The purpose of this study was to review the outcome of endovascular abdominal aortic aneurysm repair (EVAR) using custom-made aortouni-iliac (AUI) devices with femorofemoral bypass. Between June 1999 and March 2001, 23 consecutive patients (1 female, 22 male) at high risk of open aortic aneurysm repair underwent EVAR with custom devices in an AUI configuration. The mean follow-up was 37 months (range 2–72 months), and the mean age was 76.8 years (range 67.5–88.7 years). Increased surgical risk was evidenced by 92% and 69% of patients with significant pulmonary or cardiac disease, respectively. The preoperative mean aneurysm diameter ( n = 23) 62 ± 8.2 mm was significantly greater than the postoperative diameter, ( n = 23) 54 ± 16.4 mm. Ten endoleaks occurred. Migration of the stent graft occurred in 9% ( n = 2). Secondary interventions were necessary in 23%, whereas tertiary interventions were required in 9%. Patients at high risk of open aneurysm repair received sufficient protection from aneurysm rupture with custom-made AUI devices.
