Perioperative Outcomes for Abdominal Aortic Aneurysm Repair Based on Aneurysm Diameter.

There were no differences in perioperative outcomes after AAA repair, independent of aneurysm diameter. We found a higher likelihood of repairing AAA ≤5.4 cm in younger patients who were more likely to have been repaired with EVAR. Patients older than 80 years were less likely to undergo small AAA repair.
