Dural arteriovenous fistulas (DAVFs) are direct shunts between extracranial or meningeal arteries and dural sinuses, dural veins, or cortical veins. They account for 10%-15% of all intracranial vascular malformations. DAVFs are classified according to two classification systems, Borden and Cognard, both of which are based on the venous drainage pathway and presence of antegrade or retrograde venous flow. A multidisciplinary approach using endovascular techniques has become the mainstay of treatment. We present two cases of DAVF with cortical venous drainage (Borden type 3) that were successfully treated using a transvenous approach via the draining subarachnoid veins.
硬脑膜动静脉瘘（DAVF）是颅外或脑膜动脉与硬脑膜窦、硬脑膜静脉或皮质静脉之间的直接分流。它们占所有颅内血管畸形的 10%-15%。DAVF 根据两种分类系统进行分类，Borden 分类法和 Cognard 分类法，这两种分类法均基于静脉引流途径和是否存在顺行或逆行静脉血流。采用血管内技术的多学科方法已成为主要的治疗方法。我们报告了两例通过引流蛛网膜下腔静脉的经静脉入路成功治疗的皮质静脉引流（Borden 3 型）DAVF。
