Abstract

OBJECTIVES:

The purpose of this retrospective, single-institution study is to describe a 4-year experience of examining early and late clinical outcomes after endovascular repair of abdominal aortic aneurysm (AAA).

MATERIALS AND METHODS:

Between October 1998 and January 2003, 455 patients were submitted for AAA treatment, of whom 269 underwent open repair and 186 were treated with an endovascular procedure. All endovascular-treated patients underwent preoperative arteriography, contrast enhanced CT scanning or spiral-CT to define the morphological characteristics of the aneurysm, including precise diameter and length measurements.

RESULTS:

Technical success was achieved in 182 (98%) of the endovascular procedures, as intraoperative conversions to open repair and/or aborted procedures occurred in four patients. The perioperative (30-day) mortality rate was 1% (two patients). During the follow-up period (9-60 months) CT, duplex ultrasound scanning and plain abdominal X-ray evaluation were performed at 3, 6, 12 months, and annually thereafter. Type I endoleak occurred in 12 patients (6.6%), required a further endovascular procedure (11) or late conversion to open repair (1). Type II endoleak occurred in five patients (3%).

CONCLUSIONS:

In our clinical experience the endovascular repair of AAA is a safe and effective technique with good mid-term results in patients at standard and high risk.
