Objective To explore the techniques and efficacy of Neuroform stent -assisted coiling of intracranial wide - necked aneurysms. Method 187 consecutive patients with 190 wide - necked intracranial aneurysms were treated with the Neuroform stent - assisted coiling. The technical feasibility of the procedure, procedure - related complications, angiographic results, clinical outcome and follow - up angiography were evaluated retrospectively. Results In each cases, the Neuroform stent system was delivered and deployed accurately, and occlusion was achieved. Immediate angiography demonstrated complete occlusion in 88. 9% , neck remnant in 6.9% , and incomplete occlusion in 4. 2%. Procedure - related morbidity was 5.9% and procedure - related mortality was 1. 1% . Favorable clinical outcome (Modified Rankin Scale score 0～2) was observed in 87. 7 % of the patients(average follow - up time,47. 3 months). No rehemorrhage of treated aneurysm occurred. Angiography follow - up was obtained in 47. 9% (89/187 patients;91/190 aneurysms; average follow - up time,40. 8 months). The overall recanalization rate was 8. 7%. Comparison of occlusion class immediately after treatment and at last follow - up showed 86. 8 % of the 91 aneurysms had stable or improved class. 7 aneurysms (41. 2% ) that were not initially completely occluded converted to complete occlusion on follow - up. No delayed coil or stent migration was found. One patient with in - stent stenosis and one with penetrating artery occlusion occurred as delayed complications. Conclusions In treating wide - necked intracranial aneurysms, the Neuroform stent - assisted coiling is a secure and effective technique.%目的 探讨应用Neuroform支架辅助栓塞治疗颅内宽颈动脉瘤的效果.方法 回顾性分析Neuroform支架辅助栓塞治疗的187例颅内动脉瘤患者的临床资料及随访结果 .结果 术中支架均顺利到位,放置满意.即刻造影完全栓塞88.9%,次全栓塞6.9%,不全栓塞4.2%.操作相关致残率和死亡率分别为5.9%和1.1%.临床随访87.7%患者预后满意(mRS 0～2分),术后无再出血发生.造影随访总体再通率8.7%.无支架或弹簧圈移位发生.迟发性并发症包括1例支架内狭窄和1例眼动脉闭塞.结论 Neuroform支架辅助弹簧圈栓塞治疗颅内宽颈动脉瘤中期疗效肯定.
