Acute occlusion of the artery to a single functioning kidney is a rare but surgically correctable cause of acute renal failure. A young-aged woman with acute renal failure and anuria due to a thromboembolism of the right renal artery was surgically treated 2 hours after the onset of anuria. Revascularization resulted in the reversal of renal failure and complete recovery of renal function. An aggressive diagnostic and therapeutic approach is important whenever occlusion of the renal artery is suspected during surgery in Takayasu arteritis patients.
