A 73-year-old man with a history of hypertension and drug-induced hepatitis underwent surgical treatment of an enlarging pararenal abdominal aortic aneurysm (PRAAA) with bilateral renal artery stenosis, found on enhanced computed tomography (CT). His preoperative renal function was normal. We divided the right renal artery and used a 6-mm expanded polytetrafluoroethylene (ePTFE) tube graft for the anastomosis. Renal artery perfusion was achieved by a rapid infusion pump set at 200 ml/min. The left renal artery was reconstructed and perfused in the same way. The abdominal aorta was cross-clamped just distal to the superior mesenteric artery and a Y-graft was anastomosed. The ePTFE grafts were connected to the Y-graft and bilateral renal artery circulation was re-established. The renal ischemic time was 1 h 25 min and the urine output during reconstruction was 80 ml. Postoperatively, his serum blood urea nitrogen and serum creatinine levels increased slightly, but normalized within 3 days. This case report shows that this method of renal artery perfusion could prove useful for complex renal artery reconstructions.
