Case report reveals successful treatment of intraosseous AVF in the mastoid canal using combined endovascular methods, suggesting effective management strategies.
Objective: The mastoid emissary veins (MEVs) traverse the mastoid emissary canal (MEC) and connect the sigmoid sinus to the extracranial venous system. Although MEVs are frequently identified on angiography, an intraosseous arteriovenous fistula (AVF) arising primarily within the MEC has not been previously reported. Herein, we report a rare case of intraosseous AVF of the MEC that was successfully treated using a combined endovascular approach.
