Extracorporeal microvascular arterial reconstruction in donor kidneys prior to transplantation.

Revascularization of all renal arteries is important to the prevention of ischemic allograft complications. Extracorporeal arterial repair prior to transplantation was performed on 41 donor kidneys. Three extracorporeal reconstructive techniques are described that are applicable to most of the anatomic variants presented by multiple renal arteries and those that are damaged or diseased. These are simple and effective methods that avoid subjecting the kidney to prolonged ischemia.
