Key result
Endovascular aneurysm repair using custom-made aortouni-iliac devices significantly reduced mean aneurysm diameter from 62 mm to 54 mm in patients at high risk for open repair.
Why the study?
Does EVAR using custom-made AUI devices with femorofemoral bypass reduce aneurysm diameter and prevent rupture in patients at high risk for open repair?

Does EVAR using custom-made AUI devices with femorofemoral bypass reduce aneurysm diameter and prevent rupture in patients at high risk for open repair?
Custom-made AUI devices for EVAR provide sufficient protection from aneurysm rupture in high-risk patients, significantly reducing aneurysm diameter despite a notable rate of endoleaks and secondary interventions.
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.

Hakaim et al. (2006) conducted an observational in abdominal aortic aneurysm (n=23). Endovascular abdominal aortic aneurysm repair (EVAR) using custom-made aortouni-iliac (AUI) devices was evaluated on mean aneurysm diameter. Endovascular aneurysm repair using custom-made aortouni-iliac devices significantly reduced mean aneurysm diameter from 62 mm to 54 mm in patients at high risk for open repair.
