Abstract

Purpose: To present a real-world experience of the elective treatment of abdominal aortic aneurysms (AAAs) using both open repair (OR) and endovascular repair (EVAR).

Methods: Data from patients treated consecutively between January 1, 2000 and December 31, 2014 were collected retrospectively and reviewed. The primary outcomes were 30-day mortality and complication rates, freedom from reintervention, and survival in the long-term.

Results: We analyzed data on 1112 patients (660 EVAR, 452 OR). The 30-day mortality and complications rates were higher after OR than after EVAR (2.9 vs. 1.1%, P = .03 and 24.7 vs. 1.1%, P < .0001, respectively). At 10 years, survival was 66.1 ± 3.2% after OR and 78.1 ± 2.2% after EVAR (P = .0006) and freedom from reintervention was 93.5 ± 1.8% after OR and 88.4 ± 1.8% after EVAR (P = .005). The preoperative aneurysm diameter was significantly associated with the development of type Ia endoleaks after EVAR (P < .0001) and of a proximal pseudoaneurysm after OR (P < .0001).

Conclusion: In the long-term, EVAR was associated with higher reintervention rates, but better survival than OR. The preoperative AAA diameter was the most important predictor of the development of endoleaks after EVAR and proximal pseudoaneurysm after OR.
