The most commonly employed procedures for the treatment of main renal artery stenosis are aortorenal bypass, with autogenous or synthetic material, and transrenal endarterectomy.
Our recent experience with the technique of renal endarterectomy through a longitudinal aortotomy has shown it to be an acceptable alternative in the treatment of arteriosclerotic lesions of the renal artery. The fact that renal arteriosclerotic stenosis is generally not an isolated lesion, but rather an extension of aortic arteriosclerosis, produces advantages for this technique over bypass grafting and over endarterectomy through a renal arteriotomy.
