Early endovascular treatment has become the standard reperfusion therapy for ischemic stroke due to large vessel occlusion （LVO）， and intracranial atherosclerotic stenosis （ICAS） is one of the main causes of ischemic stroke due to LVO in Asian people. For such lesions， emergency mechanical thrombectomy may lead to early reocclusion， and compared with cardiogenic embolism， it often requires more rescue measures and a longer time of operation to achieve successful revascularization. There is still a lack of evidence-based medicine support for the optimal treatment strategy for ICAS-related LVO. Therefore， it is of great importance to early identify ICAS-related LVO and formulate reasonable and effective endovascular treatment strategy before surgery. This article reviews the recent studies on the endovascular treatment of ICAS-related LVO.
