Abstract

Multiple craniofacial arteriovenous malformations (AVM) are rare, and they are hemodynamically related to each other by complex and intercommunicating vascular networks. This report presents a case with two craniofacial AVMs located in anatomically different regions. One AVM changed in flow amount and venous drainage route after embolization of the other one, which may suggest a new guideline for treatment of multiple craniofacial AVMs.
