A Retrospective Study of Reco Thrombectomy Stent for Intravascular Treatment of Acute Ischemic Stroke

Study Overview
=================
Brief Summary
-----------------
To explore the differences in the green channel process of stroke in various regions of the same province, to target and shorten the time delay of emergency process, and to explore the key technologies of endovascular treatment of acute ischemic stroke. To investigate the use and embolectomy effect of Reco, the first embolectomy stent in China, in economically developed areas. Health economic assessment (cost-benefit analysis) of ischemic stroke patients in various regions of the province.

Detailed Description
-----------------
The Reco Embolectomy Stent is indicated for patients who cannot be treated with intravenous tissue activator (IVt-PA) or who have failed IVt-PA therapy and is intended to remove thrombus from a large intracranial vessel in patients with ischemic stroke to restore blood flow.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The time between the onset of the disease and the opening of the blood vessels | Calculate the time from onset to vessel opening | Immediately after surgery | 
| Functional independence at 90 days (defined as mRS≤2) | mRS scores were performed 90 days after surgery | 90day after surgery | 
| Symptomatic intracranial hemorrhage within 24 hours after surgery | Symptomatic intracranial hemorrhage was evaluated by CT 24 hours after operation | 24 hours after surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time from onset to admission | Calculate the time from onset to admission | Immediately after surgery | 
| Time from admission and puncture time | Calculate the time from onset to admission | Immediately after surgery | 
| Puncture to the time of vessel opening | Calculate the time from puncture to vascular opening | Immediately after surgery |
