[Renal-sparing procedures in the management of renal arteriovenous fistula].
Five cases of renal arteriovenous fistula which were treated by renal-sparing procedures are reported. Transcatheter arterial embolization was performed in three cases of circoid type arteriovenous fistula. Gross hematuria stopped immediately after the treatment in these three cases. Another two patients, whose arteriovenous fistula were aneurysmal type, were treated by ligation of the feeding artery. Although there were no symptoms after the surgery, the follow-up renal arteriography revealed the residue of a small amount of arteriovenous fistula in one of the aneurysmal type cases. We suggest that the renal arteriovenous fistula be classified into circoid type and aneurysmal type in the diagnosis for the appropriate treatment of renal arteriovenous fistula. It is important to select the renal-sparing procedure according to the type of renal arteriovenous fistula.
