[Bilateral stenosis of the renal arteries: transaortic endarterectomy]

Transaortic renal endarterectomy with infra-renal aortic prosthetic graft may be used to treat combined aortic and renal atherosclerosis. We present herein the technics we used in seven patients, which represented 0.4% of our aortic revascularizations and 15% of our combined aortic and renal revascularizations. All these patients were hypertensive and four had a mild preoperative renal insufficiency. Post-operatively there were no death and the morbidity rate was 12%. Morphological assessment showed no renal or limb graft occlusion. During the follow-up there were three deaths, one limb graft occluded. All renal arteries remained patent with improvement of hypertension in 70% and stabilisation of the renal function in all. In carefully selected cases, transaortic renal endarterectomy is a safe and efficient method of treatment of combined aortic and renal atherosclerotic disease.
