Three unusual arteriovenous fistulas presenting in young children successfully treated with transarterial endovascular embolization.

Endovascular approaches can be utilized to manage arteriovenous fistulas (AVFs) either as a stand alone therapy or in conjunction with surgical excision. The goal of treatment is to completely obliterate the AVF. These vascular malformations are rare in childhood and pose a treatment challenge. We describe 3 children who were diagnosed with vascular malformations on magnetic resonance imaging and were subsequently found to have unusual AVFs on angiography. These single-feeder fistulas were successfully occluded with transarterial embolization using platinum coils. Copyright (c) 2005 S. Karger AG, Basel.
