BACKGROUND: We report a 15-year experience with renal artery revascularization during abdominal aortic aneurysm (AAA) repair.
METHODS: AAA repairs from 1994 to 2009 were reviewed. Postoperative complications, renal function, patency, and survival in patients undergoing renal artery revascularization were evaluated and compared with a control group of patients undergoing juxtarenal AAA repairs not requiring renal artery revascularization.
RESULTS: Sixty patients underwent renal artery revascularization during AAA repair. Transient postoperative renal insufficiency occurred in 20 patients. Temporary hemodialysis was required in 3 patients, with none requiring permanent hemodialysis. There was I postoperative death. There was I renal artery revascularization failure at 1 month but no other graft failures at 12 months median follow-up evaluation (1-year patency, 97%). In comparison with the control group, transient renal insufficiency and pulmonary complications (33.3% vs 19.8%; P = .042) were more common with renal artery revascularization, with no differences in long-term renal complications or mortality.
CONCLUSIONS: Renal artery revascularization can be performed during AAA repair with excellent patency and minimal morbidity.
