The role of renal autotransplantation in pediatric and young adult patients with renal artery disease

Abstract

From 1977 to 1984, renal autotransplantation was attempted in 16 pediatric and young adult patients with renal artery disease, ranging in age from 10 months to 21 years. Renal revascularization was indicated as treatment for severe hypertension in 15 patients and to prevent rupture of an arterial aneurysm in one patient. The reasons for undertaking renal autotransplantation were branch renal artery disease requiring extracorporeal revascularization (n = 14), abdominal aortic hypoplasia (n = 1), and renal artery disease in a small infant (n = 1). Renal revascularization was successfully accomplished in 14 of 16 patients, including one patient who underwent staged bilateral extracorporeal repairs. Obliteration of the inferior vena cava and iliac veins precluded autotransplantation in one patient and a nephrectomy was done. In one patient extracorporeal ligation of an inaccessible renal arterial branch was accomplished with autotransplantation. Currently all 16 patients are normotensive with excellent renal function. Extracorporeal surgery and autotransplantation have been important additions to the surgical armamentarium for renal artery disease.
