The authors describe a novel technique involving the use of a gooseneck snare for microcatheterization of isolated sinus dural arteriovenous fistulas (DAVFs). In some patients the inferior petrosal and transverse-sigmoid sinuses, the route of transvenous embolization (TVE) for DAVF, are separated by several channels. Even if a guidewire can be passed over the occluded portion and the affected sinus can be accessed, one may not necessarily be able to insert a microcatheter. The authors report on three patients who underwent successful microcatheterization via a novel pull-up technique, which makes use of a gooseneck snare to perform TVE even in very difficult circumstances.
作者描述了一种新技术，该技术涉及使用鹅颈圈套器对孤立性窦硬膜动静脉瘘（DAVF）进行微导管插管。在一些患者中，DAVF经静脉栓塞术（TVE）的路径——岩下窦和横窦-乙状窦，被多个通道分隔开。即使导丝能够越过闭塞部分并进入受累窦，也不一定能够插入微导管。作者报告了三名患者，他们通过一种新的上拉技术成功进行了微导管插管，该技术利用鹅颈圈套器即使在非常困难的情况下也能进行TVE。
