To determine the best treatment for high-risk patients with abdominal aortic aneurysms (AAA). We reviewed a prospective database of all patients who underwent conventional (OPEN) or endovascular aneurysm repair (EVAR) between January 1998 and December 2002.

Continuous data were expressed as mean +/- standard deviation. All data were calculated using the cumulated actuarial method of event outcome probability. Kaplan-Meier curves were constructed and the log-rank statistic and chi squared test were used for comparative data. P values less than 0.05 were considered to indicate statistical significan...
