Investigate Reco ® ,the first clot retriever in china as the primary therapyand remedies in the real world.
Endovascular thrombectomy (EVT) is effective and safe for acute ischemic stroke (AIS) caused by large vessel occlusion (LVO) in major clinical trials. Whether the benefit of EVT in randomized trials could be generalized to clinical practice, especially in developing countries, remains unknown. The Registry was established to evaluate the utilization, and subsequent outcomes of EVT treated AIS patients. This study is a multi-center, prospective registry study initiated by researchers, to investigate Reco ® ,the first clot retriever in china as the primary therapyand remedies in the real world.

| EQ-5D 90 days after the procedure | EQ-5D is a standardized instrument for measuring generic health status. Rated level can be coded as a number 1, 2, or 3, which indicates having no problems for 1, having some problems for 2, and having extreme problems for 3. As a result, a person's health status can be defined by a 5-digit number, ranging from 11111 (having no problems in all dimensions) to 33333 (having extreme problems in all dimensions).A higher score indicates a better outcome. | 90±7 days after the procedure |
| Barthel index (BI) 90 days after the procedure | The BI has a score of 0-100. A higher score indicates a better outcome. | 90±7 days after the procedure |

| All-cause mortality within 90 days | mortality | 90±7 days after the procedure |
