Reoperation rates after open and endovascular abdominal aortic aneurysm repairs.

The long-term burden of reoperations after OR may actually be more significant than current understanding when including all possible abdominal complications in an extended analysis. Future prospective trials should include all potential reoperations extended >30 days with associated cost analysis. As surgical innovation in EVAR technology advances, complication comparisons with OR should undergo frequent re-evaluation given that endovascular indications and outcomes continue to expand and improve.
