Abstract

BACKGROUND AND OBJECTIVE
Although the endovascular method of treating abdominal aortic aneurysms (AAA) shows good early results and benefits, the late outcome of this treatment remains uncertain. This study evaluated the late outcome following an endovascular AAA repair.
SUBJECTS AND METHODS
Thirty-three patients that had undergone an endovascular AAA repair at our institute were evaluated. The results of the treatment were evaluated by an angiography, taken just after the completion of the procedure, and by contrast-enhanced CT scans at 1, 3, 6 and 12 months, and annually thereafter.
RESULTS
The patient's characteristics were as follows: 29 (88%) were male, 19 (58%) had coronary artery disease and 7 (21%) had renal insufficiency. A technical success was achieved in 31 patients (94%), with primary endoleaks in two. Two patients (6.1%) died within 1 month of the procedure, both at an elderly age, with high risk. There was 1 (3%) incidence of early complications that required treatment. During the 28 month follow-up period, 6 patients (20%) needed a secondary procedure. Endoleaks remained in 4 patients, and the size of aneurysm increased in 3 patients. Four patients died during follow-up, and two had an endoleak. The cause of death was not related to cardiovascular diseases in the other two patients. The event free survival at 24 months was 72%.
CONCLUSION
The late outcome after an endovascular AAA repair was favorable. However, a secondary procedure was needed, and endoleaks observed, in half of the patients that died during follow-up. Therefore, regular evaluation of aneurysms and the management of endoleaks are very important for a favorable late outcome in endovascular AAA repair patients.
