Use of the gastroduodenal artery in right renal artery revascularization

Abstract Of 15 patients having revascularization of the right renal artery with the use of the hepatic circulation from May 1984 through March 1987 at the Massachusetts General Hospital, eight patients had this accomplished with end-to-end anastomosis of the gastroduodenal artery and right renal artery. Operative indications were acute azotemic renal failure (three patients), poorly controlled renovascular hypertension (four patients), and staged repair of bilateral renal artery disease (one patient). All revascularizations were successful in restoring renal function or rendering hypertension manageable and were assessed by means of renal flow scans, celiac angiography, or return of function in those patients with a solitary, functioning kidney. All patients survived the operation with one late death caused by myocardial infarction after abdominal aortic aneurysm repair. The gastroduodenal artery may be used as the source for arterial inflow in revascularization of the right renal artery by end-to-end anastomosis in approximately 50% of instances, confering the advantage of the use of only one anastomosis and obviating the long-term possibility of vein graft failure.
