Dural Arteriovenous Fistula within the Hypoglossal Canal Successfully Treated by Transvenous Embolization. Case Report.
We report a case of dural arteriovenous fistula (DAVF) within the left hypoglossal canal in a 64-year-old man who presented with tinnitus and ocular symptoms. Angiography revealed DAVF with the fistulous pouch medial to the left jugular bulb. The fistula was feeded by meningeal branches of the bilateral ascending pharyngeal arteries and the branches from the left vertebral artery. The fistula shunted into the left jugular bulb, with reflux into the left inferior petrosal (IPS) and cavernous sinuses (Cses), left superior ophthalmic vein (SOV) and cortical veins over the cerebral convexity. We performed transvenous coil embolization to occlude the fistula resulting in complete resolution of symptoms and signs.
