Selective renal artery embolization for control of biopsy-induced bleeding

Two cases of selective renal artery embolization for control of bleeding induced by arteriovenous malformation are described. Both cases occurred after percutaneous renal biopsy and involved massive hematuria, unresponsive to conservative treatment. Arteriography in both cases demonstrated an arteriovenous fistula in the area of the biopsy, and selective embolization with an artificial clot resulted in prompt cessation of bleeding. In one case, follow-up angiograms showed a minimal anatomic defect, and renal function studies were unchanged. Selective renal artery embolization is an acceptable method for correcting bleeding due to biopsy-induced arteriovenous malformation.
