title: Iliorenal artery bypass grafting to facilitate endovascular abdominal aortic aneurysm repair.
abstract: Effective endovascular repair of an infrarenal abdominal aortic aneurysm (AAA) requires adequate proximal and distal landing zones to allow secure endograft attachment. We report a patient with an infrarenal AAA originating 3 mm below the left renal artery with cardiac morbidity that precluded open AAA repair. Left renal artery relocation with retroperitoneal iliorenal bypass grafting was performed to lengthen the proximal landing zone, which facilitated successful endovascular AAA repair. Postoperative surveillance after 3 years showed aneurysm reduction with a patent iliorenal bypass graft. This case underscores the utility of a combined open and endovascular approach in treatment of a challenging aortic aneurysm.
