Results of Endovascular Abdominal Aortic Aneurysm Repair with the Zenith stent-graft

Abstract Objective To evaluate single center results of the Zenith stent-graft for elective abdominal aortic aneurysm repair. Methods Data from all patients treated with a Zenith graft between March 1999 and December 2006 were retrospectively analyzed from a prospective database. Outcome measures we...

Summary:Abstract Objective To evaluate single center results of the Zenith stent-graft for elective abdominal aortic aneurysm repair. Methods Data from all patients treated with a Zenith graft between March 1999 and December 2006 were retrospectively analyzed from a prospective database. Outcome measures were technical success, all-cause and aneurysm related mortality, late complications, and re-interventions. Results A total of 234 patients were included, of which 216 were male. Mean age was 72.1 ± 6.9 years. Mean diameter of the aneurysm was 60.9 ± 10 mm. Technical success rate was 98.3%. Thirty day mortality was 1.7%. Median follow-up was 26.9 months (range, 1–104). Overall survival was 92.2 ± 1.8% at 1 year, 87.2 ± 2.3% at 2 years, and 69.9 ± 4.6% at 5 years. During follow-up, one aneurysm ruptured due to limb disconnection, which was treated by bridging stent-grafting. Re-interventions were performed in 9.2% of the patients, with 79% by endovascular means. There was no mortality related to re-intervention. Conclusions Endovascular abdominal aortic aneurysm repair with the Zenith device provides excellent results with a low risk for aneurysm-related death and rupture, and a low re-intervention rate in the mid-term.
