Multiple-artery renal transplantation: emphasis on extracorporeal methods of donor arterial reconstruction

The operative techniques to transplant kidneys with multiple renal arteries and our recent experience with them are reviewed. The preferred methods are anastomosis with a Carrel aortic patch and extracorporeal arterial repair before transplantation. These are simple and effective methods that avoid subjecting the kidney to prolonged ischemia. Revascularization of all renal arteries is important to obviate ischemic allograft complications.
