急性基底动脉闭塞超时间窗支架取栓术治疗的疗效分析

目的 探讨急性基底动脉闭塞超时间窗Solitaire支架机械取栓术治疗的安全性和有效性。方法 回顾性分析2016年10月至2018年10月超时间窗Solitaire 支架机械取栓术治疗的8例基底动脉闭塞病人的临床资料。结果 8例经Solitaire 支架机械取栓后均成功获得再通。术前NIHSS评分为（24.83±2.71）分，术后30 d为（14.12±2.48）分，术后90 d为（8.12±2.48）分，两两比较差异有统计学意义（P<0.05）。术后3个月改良Rankin量表 评分1分1例，2分1例，3分2例，4分2例，5分2例。MRA或CTA复查显示，1例血管闭塞（左侧大脑后动脉），余7例无开通血管再闭塞。结论 超时间窗Solitaire 支架机械取栓术治疗急性基底动脉闭塞是有效的、相对安全。

Basilar artery occlusion treated by mechanical thrombectomy with the Solitaire device more than 24 h after stroke

Objective To investigate the effect of mechanical thrombectomy with Solitaire device more 24 hours after stroke on acute basilar artery occlusion and its safety. Methods The mechanical thrombectomy with Solitaire device was performed more than 24 hours after the stroke in 8 patients with acute basilar arteries occlusion from October, 2016 to October, 2018. The curative effects were assessed by (American) National Institutes of Health stroke scale (NIHSS) before the thrombectomy and 30 and 90 days after the treatment. The clinical prognosis was evaluated with modified Rankin Scale (mRS) 90 days after the treatment. Results The complete recanalization of ocluded basilar arleries was achieved by mechanical thrombectomy with Solitaire device in all the patients. NIHSS scores were significantly lower after the treatment than those before the treatment (P<0.05). The prognosis was good in these 8 patients according to mRS 90 days after the treatment (P<0.05). Conclusion The mechanical thrombectomy with Solitaire device more than 24 hours after the stroke is safe and effective in the patients with acute basilar arteries occlusion
