Key result
Infrarenal abdominal aortic aneurysm repair resulted in 30-day mortality of 6.1% for asymptomatic elective, 5.8% for symptomatic elective, 14.1% for symptomatic emergency, and 37% for ruptured AAA.

Mortality after infrarenal AAA repair remains high in emergencies; cohort data leaves open whether rising age and comorbidities explain stagnant outcomes.
Cohort (n=1,515)
No
Over a 21-year period, operative mortality for AAA repair did not improve and may be increasing, possibly due to advancing patient age and comorbidities.
Bradbury et al. (1998) conducted a cohort in Infrarenal abdominal aortic aneurysm (AAA) (n=1,515). Infrarenal abdominal aortic aneurysm (AAA) surgery was evaluated on 30-day and/or same admission mortality. Infrarenal abdominal aortic aneurysm repair resulted in 30-day mortality of 6.1% for asymptomatic elective, 5.8% for symptomatic elective, 14.1% for symptomatic emergency, and 37% for ruptured AAA.
