摘要颅内外大动脉闭塞与脑缺血性事件的发生密切相关。对于急性大血管闭塞所致的缺血性卒中，血管内介入治疗已被证实是时间窗内的有效治疗方案。但是，对于颅内外大动脉非急性闭塞的介入治疗，目前国内尚缺乏统一的认识。为此，中华医学会神经病学分会神经血管介入协作组、中国医师协会神经内科医师分会神经介入专业委员会、中国研究型医院学会介入神经病学专业委员会组织国内部分脑血管病专家就上述问题展开讨论，并达成共识，以期为临床医师在颅内外大动脉非急性闭塞的介入治疗提供参考依据。

abstractsOcclusion of intracranial and extracranial large vessel is closely related to the occurrence of cerebral ischemic events. Endovascular treatment has been proven to be an effective treatment in ischemic stroke due to acute large vessel occlusion within the time window. At present, there is a lack of unified understanding on endovascular treatment for non-acute occlusion of intracranial and extracranial large vessel in China. Neurovascular Intervention Group of Chinese Society of Neurology, Chinese Medical Doctor Association, Society of Neurology, Professional Committee of Neurological Intervention and Chinese Research Hospital Association, Professional Committee of Interventional Neurology organized some cerebrovascular disease experts in China to discuss that and form this expert consensus.
