Abstract

Background: Endovascular aortic aneurysm repair (EVAR) has come into use and been widely extended because of the low complication rate and less-invasiveness. This article aimed to describe our experience in the treatment of abdominal aortic aneurysm with EVAR. Materials and Methods: A retrospective review was conducted for the 22 patients who underwent EVAR in a single hospital December 2001 to June 2009. Results: The mean age of the patients was $68.5{\pm}7.6$ years. There were several risk factors and comorbidities in 20 patients (90.9%). The mean diameter of the aortic aneurysms was $61.2{\pm}12.9$ mm. The mean length, diameter, and angle of the aneurysmal neck were $30.5{\pm}15.5$ mm, $24.0{\pm}4.5$ mm, and $43.9{\pm}16.0^{\circ}$, respectively. The mean follow-up period of the patients was $28.8{\pm}29.5$ months. The 30-day postoperative mortality was none. Seven patients (31.8%) had endoleaks during the hospital stay and three patients (13.6%) had endoleaks during the follow-up period. One patient (4.5%) died due to a ruptured aortic aneurysm. The cumulative patient survival rates were 88.2%, 88.2%, and 70.6% at 1, 3, and 5 years of follow-up, respectively. Conclusion: EVAR is currently a safe, feasible procedure for high risk patients with abdominal aortic aneurysm because of low postoperative complication and mortality if patients are selected properly and followed up carefully.
