We report a case of an elongated middle cerebral artery bifurcation aneurysm which was managed using an endovascular double catheter technique. After positioning two microcatheters, one at the distal dome and the other at the proximal dome, two coils were subsequently deployed through each microcatheter.We created a proximal supporting coil frame using one microcatheter and preserved the parent artery, and then deposited subsequent packing coils at the distal aneurysm sac region using the other microcatheter. The proximal framing coils did not detach prior to obtaining satisfactory aneurysm packing through the distally positioned microcatheter. This approach allowed for the proximal coil to be withdrawn if there was any evidence of the proximal coil frame changing shape or of parent artery protrusion. This double microcatheter technique provided safe and effective treatment of an elongated middle cerebral artery bifurcation aneurysm.
我们报告一例使用血管内双导管技术治疗的大脑中动脉分叉部延长型动脉瘤病例。在放置两根微导管后，一根置于动脉瘤远端瘤顶，另一根置于近端瘤顶，随后通过每根微导管分别置入两个弹簧圈。我们使用一根微导管构建近端支撑弹簧圈框架并保留载瘤动脉，然后使用另一根微导管在远端动脉瘤囊区域放置后续的填塞弹簧圈。在通过位于远端的微导管获得满意的动脉瘤填塞之前，近端框架弹簧圈未发生脱落。如果有任何近端弹簧圈框架变形或载瘤动脉突出的迹象，这种方法允许撤回近端弹簧圈。这种双微导管技术为大脑中动脉分叉部延长型动脉瘤提供了安全有效的治疗。
