title: [A case of bleeding dural arteriovenous fistula of the transverse-sigmoid sinus with pure leptomeningeal drainage, varix: case report].
abstract: We reported a case of bleeding from the varix of a transverse-sigmoid sinus dural arteriovenous fistula with pure leptomeningeal drainage. A 55-year-old man presented with visual disturbance. neurological examination revealed left homonymous hemianopsia. CT scans demonstrated a subcortical hemorrhage in the right occipital lobe. Right external carotid angiograms showed a dural arteriovenous fistula of the transverse-sigmoid sinus fed by middle meningeal arteries and the occipital artery. The draining vein was the cortical vein with a varix. Transverse and sigmoid sinuses were patent. We concluded that the cause of the subcortical hemorrhage was a varix of the dural arteriovenous fistula. Initially, we embolized the dural arteriovenous fistula using a transarterial approach with GDC. Additionally, we interrupted the draining vein of the dural arteriovenous malformation. Angiographic cure was obtained and the postoperative course was uneventful. We discussed the clinical features, and the management of this case.
