From 1962 to 1984 splenorenal bypass was performed in 69 patients with renal artery disease caused by either atherosclerosis (n = 54) or fibrous dysplasia (n = 15). Renal revascularization was performed to control hypertension in 27 patients, to preserve renal function in nine patients, and for both of these reasons in 33 patients. The mean follow-up interval is 5.4 years. Postoperatively hypertension was cured or improved in 52 of 60 patients (87%); the serum creatine level was improved or stable in 37 of 42 patients (88%) who underwent revascularization to preserve renal function. Postoperative graft thrombosis (n = 2) or stenosis (n = 3) occurred in five patients (7%). Splenorenal bypass is an excellent method of revascularization of the left renal artery, particularly for patients with a troublesome aorta that precludes performance of an aortorenal bypass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
