Abstract

OBJECTIVE:

Assessment of mortality in abdominal aortic aneurysm surgery.

DESIGN:

A 4-year cross sectional study based on a nationwide vascular registry: Finnvasc.

MATERIAL AND METHODS:

A total of 17,465 vascular interventions included 929 elective repairs for abdominal aortic aneurysms (AAA), and 610 emergency cases with 454 ruptures. Fifty-three percent of the operations were done in university hospitals, 44% in central hospitals and 3% in district hospitals.

RESULTS:

The 30-day mortality rate for AAA repair was 5.1% in elective and 46% in ruptured cases. A clear dependence of operative mortality on surgeon's experience in AAA surgery was observed, both regarding the surgeon's total vascular case load (p < 0.01) and the number of operated elective aneurysms (p < 0.01), but not the number of operated ruptured aneurysms. However, no association was found between hospital volume and mortality in AAA surgery.

CONCLUSIONS:

Vascular surgical experience clearly improves the results of elective aneurysm surgery.
