A dural arteriovenous fistula (DAVF) is an arteriovenous shunt located in the dural wall of the venous sinus or the expanded layer of the dura mater.Dural arteriovenous fistulas (DAVFs) account for approximately 10%-15% of intracranial vascular malformations.The primary goal in treating DAVFs is the complete obliteration of the arteriovenous shunt.Currently, option for treatments of Ethmoidal DAVFs include surgical resection, endovascular treatment (EVT) and stereotactic radiosurgery.In this paper we report cases of bilateral ethmoidal AVF treated endovascularly and review their clinical presentation, history of treatment options, and recent advances in endovascular management.
