An intraaortic balloon pump (IABP) was inserted through the ascending aorta during a coronary artery bypass operation. Five days later, after removal of the IABP and ligation of the end-to-side Dacron graft, the patient became acutely anuric. Abdominal aortography demonstrated a large "trapeze-shaped" thrombus which occluded both renal arteries. Following thrombectomy the patient recovered, with eventual return of renal function to the preoperative state.
