目的:探讨球囊扩张式支架在动脉粥样硬化性急性椎基底动脉闭塞血管内再通治疗中的有效性和安全性。方法:回顾性分析2017年2月至2019年8月河南省人民医院收治的发病后24 h内接受急诊血管内再通并同期行球囊扩张式支架成形治疗的动脉粥样硬化性椎基底动脉急性闭塞的16例患者资料。观察术后血管内治疗的开通率、操作相关并发症、围手术期症状性出血、术后1周美国国立卫生研究院卒中量表（NIHSS）评分改善情况和术后3个月改良Rankin量表（mRS）评分。结果:16例患者中，4例行直接球囊扩张式支架成形治疗，12例行补救性球囊扩张式支架植入治疗，技术成功率100%。球囊扩张式支架植入基底动脉（BA）4例，椎动脉颅内段8例，椎动脉起始部4例。15例患者获得完全或部分再通（脑梗死溶栓分级2b、3级），动脉穿刺至再通时间为79.0（72.3，109.3）min。1例患者术中出现栓子远端逃逸。2例术后48 h出现症状性颅内出血。8例患者术后1周NIHSS评分较入院改善≥4分。9例预后良好（术后3个月mRS评分0~3分），4例死亡。结论:对动脉粥样硬化性急性椎基底动脉闭塞患者选择性急诊行球囊扩张式支架成形治疗是可行且安全的。“,”Objective:To investigate the efficacy and safety of endovascular recanalization treatment for acute vertebral basilar artery occlusion (AVBAO) underlying intracranial atherosclerotic disease (ICAD) using a balloon-mounted stent.Methods:A total of 16 cases of consecutive AVBAO patients who underwent endovascular treatment with the balloon-mounted stent within 24 h after onset were retrospectively enrolled in Henan Provincial People′s Hospital from February 2017 to August 2019. And the recanalization rate, operation-related complications, symptomatic intracranial hemorrhage, the improvement of 1 week National Institutes of Health Stroke Scale (NIHSS) score and 3 months modified Rankin Scale (mRS) after treatment were recorded.Results:In all of the 16 patients, 4 patients underwent direct stenting angioplasty, 12 patients received salvage stenting. Stent placement was successful in all 16 patients. Balloon-mounted stent were implanted in basilar artery of 4 cases, in intracranial segment of vertebral artery of 8 cases, and in origination segment of vertebral artery of 4 cases. Recanalization was successful (thrombolysis in cerebral infarction grade 2b and 3) in 15 patients. The time between arterial puncture and recanalization was 79.0 (72.3, 109.3) min. One patient experienced distal thrombosis during surgery. Two patients suffered symptomatic intracranial hemorrhage within 48 h after surgery. The scores of the NIHSS were improved more than 4 points at 1 week after operation in 8 patients. At 3 months follow-up, 9 patients had a good outcome (mRS 0-3 points) and 4 patients died.Conclusion:Selective stenting angioplasty treatment with a balloon-mounted stent seems to be feasible and safe for AVBAO patients underlying ICAD.
