Temporary vascular bypass for perfusion of a renal transplant during abdominal aneurysmectomy

A temporary vascular bypass was utilized to maintain perfusion of a renal transplant during abdominal aortic aneurysmectomy. The shunt, of polyvinyl tubing, was placed between the upper abdominal aorta and the common iliac artery, where the perfusion pressure was only 15 mm Hg less than systemic pressure. The transplanted kidney fuctioned normally during 71 minutes of aortic cross clamping, and there was no evidence of postoperative renal failure.
