A Dural Arteriovenous Fistula in the Falx Cerebri Solely Supplied by the Distal Dural Supply of the Anterior Cerebral Artery

Dural arteriovenous fistulas of the falx cerebri are extremely rare and may be associated with the falcine sinus. The distal dural supply from the anterior cerebral artery comes via the pericallosal artery. This artery can send branches to the free edge of the falx cerebri. Dural arteriovenous fistula in the falx cerebri solely supplied by the distal dural supply of the anterior cerebral artery may be more suitable for surgical treatment rather than endovascular therapy. We describe a rare case of dural arteriovenous fistula in the falx cerebri solely supplied by the distal dural supply of the anterior cerebral artery, which was treated with surgical ligation of the draining vein.
