Brief summary
Investigate Reco ® ,the first clot retriever in china as the primary therapyand remedies in the real world.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional independence at 90 days (modified Rankin Scale of 0-2) | [90±7 days after procedure] | The range of modified Rankin Scale was from 0 to 6. 0-No symptoms;1-No significant disability;2-Slight disability;3-Moderate disability;4-Moderately severe disability;5-Severe disability;6 -Dead.A higher score indicates worse a outcome. |
| Symptomatic intracranial hemorrhage (sICH) within 12-36 hours after the procedure | 12-36 hours after the procedure | Heidelberg Bleeding Classification): new intracranial hemorrhage detected by brain imaging associated with ≥4 points total National Institutes of Health Stroke Scale (NIHSS), ≥2 points in one NIHSS category, leading to intubation/ hemicraniectomy/ EVD placement or other major medical/surgical intervention, or absence of alternative explanation for deterioration |
| Time from symptom onset to recanalization | From the time of symptom onset until the time of of the recanalization of the occluded artery, assessed up to 48 hours | Minutes |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in NIHSS score 24 hours after the procedure | 24 hours after the procedure | difference between NIHSS score 24 hours after the procedure and baseline |
| Changes in NIHSS score 7 days after the procedure or at discharge | 7 days after the procedure or discharge | difference between NIHSS score 7 days after the procedure or discharge and baseline |
| EQ-5D 90 days after the procedure | 90±7 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. |
| Barthel index (BI) 90 days after the procedure | 90±7 days after the procedure | The BI has a score of 0-100. A higher score indicates a better outcome. |
| Parenchymal hematoma (PH2) | 12-36 hours after the procedure | PH2 is defined as the rate of hematoma \>30percent in infarct area |
| Recanalization rate at the end of the procedure | Immediately after the procedure | modified thrombolysis in cerebral infarction (mTICI) 2b-3 |
| All-cause mortality within 90 days | 90±7 days after the procedure | mortality |
| Time from onset to arrival | At baseline, after arrival at the hospital immediately | record the time |
| Time from arrival to imaging | At baseline, after taking any brain imaging immediately | record the time |
| Time from imaging to puncture | At baseline, during the procedure, after successful groin puncture immediately | record the time |
| Time from puncture to recanalization | At baseline, during the procedure, after successful recanalization immediately | record the time |
| Any intracranial hemorrhage on imaging | 12-36 hours after the procedure | Based on the image |
| Recanalization rate after the first attempt | Immediately after the first attempt of endovascular treatment | mTICI score 2b-3 |
| Changes in NIHSS score immediately after the procedure | within 2 hours after the procedure | difference between NIHSS score immediately after the procedure and baseline |
