采用选择性经静脉栓塞技术治疗了2例硬脑膜动静脉瘘（DAVF）和经动脉栓塞失败的患者。将5F导管从股静脉入路推进颈内静脉球，并将导管导航通过窦腔进入DAVF的受累皮质静脉或窦旁静脉引流通道。DAVF病灶水平的静脉受体用纤维铂弹簧圈闭塞。两例患者均实现了完全血管造影治愈，静脉受体和病灶闭塞，尽管DAVF病灶旁的窦段保持通畅。经窦将弹簧圈置入DAVF的静脉通道，但在窦腔外，可导致瘘管完全闭塞，而不会损害硬脑膜窦的生理功能。
Two patients with dural arteriovenous fistulas (DAVFs) and unsuccessful transarterial embolizations were treated with a technique for selective transvenous embolization. A 5F catheter was advanced from a femoral vein access into the internal jugular bulb and a catheter was navigated through the sinus lumen into the involved cortical veins or the parasinusal venous draining channels of the DAVFs. The venous recipients at the nidal level of the DAVFs were occluded by fibered platinum coils. Complete angiographic cure was effected in both patients, with occlusion of the venous recipients and the nidus, although the sinus segments next to the nidus of the DAVFs remained patent. Placement of coils in a transsinusal route into the venous channel of a DAVF yet outside the sinus lumen can result in complete obliteration of the fistula without damage to the physiological function of the dural sinuses.
