Objective To investigate the feasibility, the curative effect and the application value of double microcatheter technique in endovascular therapy of cerebral aneurysm. Methods All the patients with wide diameter aneurysms have 13 aneurysm altogether, and all were performed endovascular therapy with double micro-catheter technique. Results Twelve of 13 cases got successful; with the successful rate of 92.30%, Aneurysm cavity disappeared immediately in DSA image after endovascular therapy. Follow-up of 2~6 years, the cavity of 7 aneurysms were obstructed totally by DSA imaging again, 4 were occluded more than 95%, and 1 was done 90%, one was done less than 80%. By Glasgow outcome scale, 9 patients had five points, 3 patients had four points, and 1 patient had fthree points. Conclusion The double micro catheter technique may be an optional, effective and more safe method during the embolization of some complicated wide-necked aneurysms.%目的 研究双微导管技术在颅内宽颈动脉瘤临床治疗中的可行性、疗效及其应用价值.方法 13例宽颈动脉瘤患者共13枚动脉瘤,采用双微导管技术行血管内栓塞治疗.结果 13枚动脉瘤采用双微导管技术12例获得成功,技术成功率为92％,栓塞后即刻血管造影显示瘤腔闭塞、未见造影剂充填.随访2～6年,复查DSA显示动脉瘤瘤腔闭塞100％者7例(53.85％),闭塞95％以上者4例(30.77％),闭塞90％者1例(7.69％),栓塞小于80％者1例(7.69％)；格拉斯预后评分,5分9例(69.23％),4分3例(23.08％),3分1例(7.69％).结论 双微导管技术是颅内宽颈动脉瘤治疗中一种可供选择、疗效确切、比较安全的的栓塞方法.
