Renal arteriovenous malformations: transcatheter embolization and follow-up

Transcatheter embolization was performed in three patients with renal arteriovenous malformations with multiple arterial feeders. The patients were followed angiographically for 6--14 months. In two cases, the malformation disappeared with focal loss of renal tissue in the region of embolization. In the third, there was recurrence of hematuria. Angiography demonstrated incomplete embolization, but the arteriovenous malformation had diminished.
