The preferred method for treating complex dural arteriovenous fistulae of the transverse and sigmoid sinuses is via endovascular, transarterial embolization using liquid embolysate. However, this treatment approach mandates access to distal dural feeding arteries that can be technically challenging by standard endovascular approaches. This video describes a left temporal craniotomy for direct stick microcatheterization of an endovascularly inaccessible distal posterior division of the middle meningeal artery for embolization of a complex left temporal dural arteriovenous fistula. The case was performed in the hybrid operative suite with biplane intraoperative angiography. Technical considerations, operative nuances, and outcomes are reviewed.The video can be found here: https://youtu.be/Dnd4yHgaKcQ.
治疗横窦和乙状窦复杂硬脑膜动静脉瘘的首选方法是通过血管内、经动脉用液体栓塞剂进行栓塞。然而，这种治疗方法需要到达远端硬脑膜供血动脉，而通过标准的血管内方法可能具有技术挑战性。本视频描述了一种左侧颞骨开颅术，用于直接穿刺血管内无法到达的硬脑膜中动脉后支远段，以栓塞复杂的左侧颞部硬脑膜动静脉瘘。该病例在杂交手术室中进行，采用双平面术中血管造影。本文回顾了技术要点、手术细节和结果。视频可在以下网址查看：https://youtu.be/Dnd4yHgaKcQ。
