title: Ocular symptoms associated with a dural arteriovenous fistula involving the hypoglossal canal: selective transvenous coil embolization. Case report.
abstract: The hypoglossal canals are an unusual location for dural arteriovenous fistulas (AVFs) to appear. One previous report of dural AVFs involving the hypoglossal canal has been published. In the present paper, the authors describe a dural AVF within the hypoglossal canal, which presented with ocular symptoms and was successfully treated by selective transvenous embolization. Magnetic resonance imaging and contralateral carotid arteriography were useful for determination of the exact location of the fistulous pouch, which was later packed with coils. Selective transvenous coil embolization with careful assessment of the location and pattern of the venous drainage of the dural AVF is a safe and effective treatment.
