Abstract
The techniques and their respective indications that have been found most effective in replacing the renal artery and its branches are presented. Aortorenal bypass and, occasionally, splenorenal bypass can be tailored to achieve in situ repair of most branch renal artery lesions. Extracorporeal renal revascularization and autotransplantation have been done on only 7 patients and are indicated only when angiography demonstrates intrarenal extension of vascular disease. Revascularization with preservation of renal parenchyma can not be achieved in almost all patients with branch renal artery disease.
