For effective transvenous embolization of DAVFs, it is important to place coils at the shunting venous pouch in the initial step of the procedure. When it was difficult to navigate a microcatheter to the shunting venous pouch due to the anatomic relationship of approach routes with targeted pouches, we navigated the microcatheters by a "turn-back technique" within the involved sinuses into the target pouches. Complete occlusion or regression of the DAVF was obtained in all cases.
为了有效地进行 DAVF 的经静脉栓塞治疗,在手术的初始步骤中,将线圈放置在分流静脉囊中非常重要。当由于接近途径与目标囊之间的解剖关系,微导管难以到达分流静脉囊时,我们通过在受累窦内的“折返技术”引导微导管进入目标囊。所有病例均获得了 DAVF 的完全闭塞或消退。
