Surgical management of branch renal artery disease: in situ versus extracorporeal methods of repair.

Herein are presented the techniques and their respective indications that have been found most effective in replacing the renal artery and its branches. 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 onar disease. Revascularization with preservation of renal parenchyma can now be achieved in almost all patients with branch renal artery disease.
