Successful interventional treatment of renal insufficiency caused by renal artery pseudoaneurysm with concomitant arteriovenous fistula.

Asymptomatic arteriovenous fistulae and pseudoaneurysms are common after renal biopsy. We present a patient with a single kidney and symptomatic pseudoaneurysm of the renal artery with concomitant arteriovenous fistula as a rare complication following surgical embolectomy. The patient developed renal insufficiency because of a significant degree of vascular steal caused by the fistula. Dialysis was performed for more than 6 months until the fistula was diagnosed. The fistula and the pseudoaneurysm were successfully treated by superselective arterial embolization with metallic coils. Renal function improved within the next 2 weeks and no further dialysis was necessary. Copyright 2000 S. Karger AG, Basel
