Arteriovenous fistula following nephrectomy.

Abstract

Arteriovenous fistula (AVF) of the renal pedicle is a rare complication of nephrectomy. Since the 1st case report in the literature, 62 cases have been reported in the world literature. A continuous abdominal or lumbar bruit is diagnosed. They may also present with symptoms of congestive heart failure and/or hypertension. 37 years following nephrectomy, a case of AVF of the right renal pedicle associated with gross proteinuria is described. The clinical diagnosis was confirmed by aortogram, and the proteinuria subsided after successful surgical management. The causes of proteinuria may be due to the hyperfiltration state. To our knowledge, there has been no previous report of this combination in the literature.
