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.
两名患有硬脑膜动静脉瘘（DAVF）且经动脉栓塞治疗失败的患者接受了选择性经静脉栓塞技术治疗。通过股静脉通路将一根5F导管推进至颈内静脉球部，并将导管经窦腔导航至受累的皮质静脉或DAVF的窦旁静脉引流通道。DAVF瘤巢水平的静脉引流支通过纤维铂金线圈闭塞。两名患者均实现了血管造影完全治愈，静脉引流支和瘤巢均闭塞，尽管DAVF瘤巢旁的窦段仍保持通畅。将线圈经窦途径放置到DAVF的静脉通道但在窦腔外，可导致瘘完全闭塞而不损害硬脑膜窦的生理功能。
