Management of intrarenal branch arterial lesions with extracorporeal microvascular reconstruction and autotransplantation.

Extracorporeal microvascular reconstruction and autotransplantation have been done on 16 patients with intrarenal branch arterial lesions. The specific indications for this approach and the microvascular reconstructive techniques used in these cases are reviewed. All revascularization procedure were successful. Vascular reconstruction with preservation of renal parenchyma is possible in most patients with extensive intrarenal branch arterial disease.
