Cerebrospinal fluid-venous fistula is an increasingly recognized cause of spontaneous intracranial hypotension.1 The site of the leak is between the dural sleeve around a spinal nerve root and the surrounding foraminal veins. In appropriately investigated patients, transvenous embolization of the draining foraminal and paraspinal veins has been shown to be an effective way of treating the disease, with low periprocedural morbidity, improvement in symptoms and radiological appearances.2 Video 1 shows the technique employed in a typical case using Onyx (Medtronic, Minnesota, USA) to embolize a CSF-venous fistula at the right T10 neural foramen. neurintsurg;14/9/948/V1F1V1Video 1Video showing the technique for trans-venous embolization of a right T10 CSF-venous fistula for the treatment of spontaneous intracranial hypotension. The first section covers patient selection and work up, before then focusing on the technical aspects of navigating through the azygos system to the target foramen and completely occluding the pathway for CSF outflow.
脑脊液静脉瘘是自发性颅内低血压越来越被认可的原因之一。1 漏口位于脊神经根周围的硬脑膜套和周围的孔静脉之间。在经过适当调查的患者中，经静脉栓塞引流孔和椎旁静脉已被证明是治疗该病的有效方法，其围手术期发病率低，症状和影像学表现改善。2 视频 1 显示了使用 Onyx（美敦力，明尼苏达州，美国）在右 T10 神经孔栓塞脑脊液静脉瘘的典型病例中采用的技术。neurintsurg;14/9/948/V1F1V1Video 1视频显示了经静脉栓塞治疗自发性颅内低血压的右 T10 脑脊液静脉瘘的技术。第一节涵盖了患者选择和准备，然后重点介绍了通过奇静脉系统导航到目标孔并完全阻塞脑脊液流出途径的技术方面。
