Post-biopsy renal arteriovenous fistula

Abstract

A 6-yr-old boy developed progressively severe hypertension, which was unresponsive to medications, 1 week after percutaneous biopsy of his renal transplant. Renal angiogram revealed an arteriovenous fistula (AVF) in the lower pole at the site of the biopsy. Case findings and resolution after embolization are described, and the current literature is briefly reviewed.
