急性缺血性卒中占脑卒中的80%左右,其治疗的关键在于尽快开通阻塞的血管,使缺血脑组织复流,挽救缺血性半暗带。静脉溶栓治疗有时间依赖性,发病后4.5h内溶栓患者获益最大,同时溶栓开始越早、组织化管理越好、院内延迟越短、患者获益越多、且风险越小。但是由于各种原因仅约3%的患者能够接受静脉溶栓治疗,且合并大血管闭塞的患者效果不佳。我科自2012年开始尝试对急性缺血性卒中患者进行扩大时间窗(发病6~8h)的动脉干预,取 Acute ischemic stroke accounted for about 80% of the stroke, the key to its treatment is to open the blocked blood vessels as soon as possible, so that ischemic brain tissue reflow to save the ischemic penumbra. Intravenous thrombolytic therapy is time-dependent. Patients receiving thrombolysis benefit the most within 4.5 hours after onset, while thrombolysis begins earlier, tissue management is better, hospital delay is shorter, patients benefit more, and the risk is lower. However, only about 3% of patients receive intravenous thrombolysis for various reasons, and patients with large vessel occlusions are ineffective. Our department from 2012 to try to extend the time window of acute ischemic stroke patients (onset of 6 ~ 8h) arterial intervention, take
