Iatrogenic preauricular arteriovenous fistula in underlying slow-flow venous malformation and its endovascular management

Abstract

Arteriovenous fistula (AVF) is direct abnormal communication with the shunting of blood from an artery to a vein without intervening capillary network. AVF in preauricular location is uncommon, and most of the cases are posttraumatic or iatrogenic. The endovascular route is the preferred approach for treating such a lesion with better cosmetic outcome, however surgical excision may be required for complex cases.
