Solitaire AB支架半释放技术结合弹簧圈栓塞治疗前循环宽颈动脉瘤

目的：探讨Solitaire AB支架半释放技术结合弹簧圈栓塞治疗前循环宽颈动脉瘤的有效性和安全性。方法对2011年1月～2013年10月33例患者34个前循环宽颈动脉瘤采用Solitaire AB支架辅助弹簧圈栓塞，回顾性分析其临床资料和疗效。结果所有患者均采用支架半释放技术，33例患者共应用Solitaire AB支架34个，均成功到位并准确释放。1个支架内血栓形成，其余无手术相关并发症。动脉瘤完全栓塞26个，瘤颈残留6个，部分栓塞2个。载瘤动脉通畅。除1例后交通动脉瘤病人术后3 d并发颅内出血死亡外，余32例临床随访6～12个月无临床症状加重，未发生再出血及缺血并发症。22例术后6～12个月行DSA随访，2个动脉瘤瘤颈有残留，未见支架内狭窄和闭塞。结论 Solitaire AB支架操作简便，采用支架半释放技术结合弹簧圈栓塞治疗前循环宽颈动脉瘤是安全的和有效的。

Semi-deployed Solitaire AB coil embolization of wide-necked anterior circulation aneurysm

Objective To evaluate the efficiency and safety of Solitaire AB coil embolization of wide-necked anterior circulation aneurysm using a semi-deployment technique.Methods From January 2011 to October 2013,34 wide-necked anterior circulation aneurysms in 33 patients were treated with stent-assisted coil embolization at our institution.The clinical records and treatment efficacy were retrospectively analyzed.Results Thirty-four stents were semi-deployed successfully on 33 patients in the desired locations of the aneurysms.In-stent thrombosis occurred in 1 patient.The aneurysms were occluded totally in 26,subtotally in 6 and partially in 2.The entire parent arteries were patent.One patient with posterior communicating artery aneurysm died from intracranial hemorrhage 3 days after the procedure.During the 6-12 month follow-up, there was no exacerbation of symptoms or newly-developed bleeding or infarction in the remaining 32 patients.Follow-up digital subtraction angiography showed no in-stent stenosis or occlusion in 22 patients and neck remnants in 2 patients.Conclusion Semi-deployed Solitaire AB coil embolization is technically easy,safe and effective in the treatment of wide-necked anterior circulation aneurysm.
