新型机械可脱弹簧圈栓塞颅内动脉瘤

目的初步应用新型的机械可脱弹簧圈(detachablecoilsystemDCS)栓塞颅内动脉瘤。方法用DCS栓塞5例动脉瘤,其中2例巨大动脉瘤。巨大动脉瘤使用J型圈编织网篮,再以其他型号的弹簧圈填充动脉瘤腔,较小的动脉瘤使用相应型号的螺旋型弹簧圈。调整位置满意后,逆时针旋转推送导丝解脱弹簧圈。结果5例中2例完全栓塞,2例近全栓塞,DCS弹簧圈的推送和调整均安全有效,解脱速度快。一例巨大宽颈动脉瘤,因弹簧圈不能停留,而放弃DSC栓塞,改行颈内动脉闭塞术。结论DCS是一种新型动脉瘤栓塞材料,使动脉瘤栓塞的手术时间缩短。J型弹簧圈的盘绕方式独特,适用于巨大动脉瘤。

Embolization of intracranial aneurysms with new mechanically detachable coils

Objective To primarily embolize intracranial aneurysms with new-developed mechanically detachable coils,which is called Detachable Coil System(DCS).Methods Five intracranial aneurysms were embolized with DCS,in which2were giant aneurysms.DCS with J coils were initially used to make baskets in giant aneurysms,and then other kinds of coils were utilized to pact the aneurysmal cavity.Whereas,spiral coils were mostly used in smaller aneurysms.Coils of DCS were detached by rotating the delivering wire after the coils were satisfactorily positioned in aneurysms.Results Two of the5cases were totally occluded with DCS.Two was sub-totally embolized.Pushing,withdrawal,and adjusting of DCS were safe and efficient.Detachment of DCS was fast.In one case of wide-necked giant aneurysm,coils could not stay inside the aneurysm,which was treated by occlusion of the parent artery.Conclusions DCS is a new addition to the interventional radiologist' s armamentarium.Detachment is faster.J coils are suitable for giant aneurysms for its unique way of coiling.But more evaluation depends on accumulation of the clinical usage.
