. Ninety-six patients, mean age 72 +/- 8 years, with an abdominal aortic aneurysm (AAA) and significant comorbidities with a vascular anatomy favorable for supporting an endovascular prosthesis underwent endovascular repair of the AAA. The 90-day survival was 100%. The incidence of endoleaks at 25-month mean follow up was 4 of 96 patients (4%). None of the 96 patients (0%) required surgical conversion of the AAA. At 14-month mean follow up after endovascular repair, the diameter of the AAA was significantly reduced from 6.2 +/- 1.2 cm to 5.0 +/- 1.1 cm (P < 0.001).
