目的:评价颅内动脉瘤GDC栓塞术的效果和并发症。材料和方法:应用GDC栓塞治疗颅内动脉瘤270例273枚。其中5例在载瘤动脉内支架置放后再行瘤腔内GDC栓塞。临床表现为动脉瘤性蛛网膜下腔出血236例,脑神经压迫症状18例,其他16例。131例在栓塞后3～15个月作了随访血管造影。结果:262例265枚动脉瘤栓塞成功,8例手术失败。动脉瘤完全闭塞或几近完全闭塞（闭塞范围>95％）217枚,大部闭塞（闭塞范围70％～95％）31枚,部分闭塞（闭塞范围<70％）17枚,与手术相关的死亡4例,与手术相关的并发症18例（其中13例经处理后无后遗症;4例轻残;1例重残）。随访脑血管造影显示动脉瘤复发9例,均为原部分栓塞患者。结论:颅内动脉瘤腔内GDC完全致密填塞的效果肯定,与手术相关的并发症发生率与操作者经验有关。
Objective: To evaluate the efficacy and complications of intracranial aneurysm GDC embolization. MATERIALS AND METHODS: 273 cases of intracranial aneurysms were treated with GDC embolization. Five of them were placed in the tumor cavity with GDC embolization after placement of the carrier intra-arterial stent. Clinical manifestations of aneurysmal subarachnoid hemorrhage in 236 cases, 18 cases of cerebral nerve compression symptoms, the other 16 cases. 131 cases were followed up for angiography 3 to 15 months after embolization. Results: 262 cases of 265 aneurysms were successfully embolized and 8 cases failed. 217 aneurysms were completely or almost completely occluded (occlusion> 95%), 31 mostly occluded (70-70% occluded), 17 partially occluded (occluded <70%) 17, 4 died and 18 complications related to surgery (13 of them were sequelae after treatment, 4 were lightly disabled and 1 were severely disabled. Follow-up cerebral angiography showed aneurysm recurrence in 9 cases, were the original partial embolization patients. Conclusion: The effect of complete dense packing of GDC in intracranial aneurysm is certain. The incidence of complications related to surgery is related to the operator’s experience.
