A 65-year-old man presented with acute headache followed by a week of nuchal and back pain. A computed tomography (CT) scan demonstrated a subarachnoid hemorrhage and varices in the basal cistern and cerebral angiography revealed a dural arteriovenous fistula (dAVF) of the lesser sphenoid wing region. The lesion was treated by endovascular surgery. Onyx (ethylene vinyl alcohol copolymer) was used for transarterial embolization. We review some anatomical and therapeutic features involving dAVF of this region and describe the feasibility and technical notes for the use of Onyx in the treatment of these lesions.
