Renal Arteriovenous Malformationに対するTranscatheter Embolizationの経験

Abstract

Two cases of renal arteriovenous malformation were treated by transcatheter embolization using Gelfoam. In both cases, hematuria disappeared in a couple of days after embolization, and no remarkable complication developed except mild flank pain and low grade fever for a few days. In one case, however, recanalization was demonstrated by renal arteriography 36 days after embolization. Herein, we described the classification of renal arteriovenous fistula and malformation. Therapeutic methods with preservation of renal function were mentioned. Embolic materials and complications of this procedure were also discussed. The increasing number of renal embolization shows the fact that this is one of the effective procedures without risk preserving renal function.
