LVIS支架辅助栓塞治疗颅内后循环动脉瘤的疗效

目的 探讨LVIS支架辅助栓塞治疗颅内后循环动脉瘤的安全性及有效性。方法 回顾性分析2015年9月至2018年5月采用LVIS支架辅助栓塞治疗的39例（40个动脉瘤）颅内后循环动脉瘤的临床资料。采用单支架27例（单支架组），双支架12例（双支架组）。结果 39例共使用LVIS支架51枚，其中40枚支架释放时一次性完全打开，10枚释放支架后采用导管导丝按摩技术后完全打开，1枚支架打开不完全。单支架组和双支架组围手术期并发症发生率（0% vs. 11.1%）无统计学差异（P>0.05）。术后即刻造影显示:单支架组和双支架组有效栓塞率（92.6% vs. 91.7%）无统计学差异（P>0.05）。术后6个月DSA复查:单支架组和双支架组动脉瘤完全闭塞率（77.7% vs. 75.0%）及复发率（7.4% vs. 8.3%）均无统计学差异（P>0.05）。术后6个月改良Rankin量表评分0分19例，1分15例，2分2例，3分3例。结论 LVIS支架辅助栓塞治疗颅内后循环颅内动脉瘤效果满意，短期影像学随访显示双支架辅助栓塞结果并不优于单支架组。

Clinical effects of LVIS devices-assisted endovascular treatment on posterior circulation intracranial aneurysms

Objective To investigate the effects of low profile visualized intraluminal support (LVIS) stent-assisted endovascular treatment on the posterior circulation intracranial aneurysms and its safety. Methods The clinical data of 39 patients with 40 posterior circulation intracranial aneurysms treated with LVIS stent-assisted coil embolization from September, 2015 to May, 2018 were analyzed retrospectively. According to the number of used stents, the patients were divided into single stent group (n=27) and double stent group(n=12), and the curative effects were compared between both the groups. Results DSA immediately after the embolization showed that the effects of aneurysmal embolization achieved Raymond gradeⅠin 6 patients, Ⅱ in 19 and Ⅲ in 2 of the single sent group and Raymond grade I in 4, Ⅱ in 7 and Ⅲ in 1 of double sent group. The good rate (modified Rankin score 0~2 points) of the prognosis was 92.3% (36/39) and the rates of aneurysmal recurrence were 7.4% and 8.3% respectively in the single sent group and double sent group 6 months after the embolization. There was no significant difference in the rates of aneurymal recurrence between both the groups (P>0.05). Conclusions The effects of LVIS stent-assisted endovascular treatment on the posterior circulation intracranial aneurysms is satisfactory. The single stent-assisted embolization is similar to double sent-assisted embolization in the curative effects on the posterior circulation intracranial aneurysms.
