[Bilateral stenosis of the renal arteries: multiple bypasses]

Bilateral ostial renal arterial stenoses are in fact atheromatous lesions of the aortic wall. These anatomic features must be considered for the treatment of such lesions. It can be achieved by bilateral renal bypass grafting with the concomitant replacement of the aorta when necessary. This combined surgery carries a certain operative risk, which has been notably lowered with the recent advances in anaesthesiology and intensive care. We consider this combined renal and aortic surgery is easier and safer than transaortic endarterectomy.
