目前急性缺血性卒中(acute ischemic stroke,AIS)早期血管开通方法主要是药物治疗(静脉溶栓),但由于严格的时间窗限制(<4.5 h),如合并大动脉闭塞再通率更低(13%~18%)~([1]),能够从此项治疗中获益的患者不到3%,治疗效果并不令人满意。近年来一些新的血管内治疗方法 (动脉溶栓、支架机械取栓、血管内支架成形术)显著提高了闭塞血管 At present, the early vascular opening method of acute ischemic stroke (AIS) is mainly drug treatment (intravenous thrombolysis), but due to the strict time window limit (<4.5 h), such as the lower recanalization rate of combined aortic occlusion 13% ~ 18%) ~ ([1]), less than 3% of patients can benefit from this treatment, the treatment effect is not satisfactory. In recent years, some of the new endovascular treatment methods (arterial thrombolysis, mechanical stent thrombolysis, endovascular stenting) significantly increased occlusion of blood vessels
