Registration of Acute Ischemic Stroke With Large and Medium-sized Vascular Occlusion in Southwest China(LMVOS)

Study Overview
=================
Brief Summary
-----------------
This study is designed to observe the treatment options in real-world clinical practice as well as the safety and efficacy of different treatment strategies.

Detailed Description
-----------------
LMVOS is a prospective, real-world registry lasting for 22 years. A total of 8000 patients with large- or medium-vessel occlusion will be enrolled.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| modified Rankin Scale (mRS) score | Ordinal distribution of mRS at 90±7 days; modified Rankin scale (range, 0 to 6, with a score of 0 indicating no disability, 1 no clinically significant disability, 2 slight disability, 3 moderate disability but remaining able to walk unassisted, 4 moderately severe disability, 5 severe disability, and 6 death) | 90±7 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Excellent functional outcome | Proportion of subjects with mRS 0-1 at 90±7 days. | 90±7 days | 
| Good functional outcome | Proportion of subjects with mRS 0-2 at 90±7 days. | 90±7 days | 
| mRS 0-3 | Proportion of subjects with mRS 0-3 at 90±7 days. | 90±7 days | 
| Change of National Institutes of Health Stroke Scale (NIHSS) | Change of National Institutes of Health Stroke Scale (NIHSS, a scale between 0 and 42 on which higher scores indicate more severe neurologic deficits) from baseline to 24 hours. | 24 hours | 
| Change of National Institutes of Health Stroke Scale (NIHSS) | Change of National Institutes of Health Stroke Scale (NIHSS, a scale between 0 and 42 on which higher scores indicate more severe neurologic deficits) from baseline to 7 days. | 7 days | 
| Symptom-to-thrombolysis time (STT) | Time from onset of symptoms to thrombolytic therapy. | 24 hours | 
| Door-to-Needle Time | Time from the arrival of stroke patient in emergency to initiation of thrombolysis therapy. | 24 hours | 
| Door-to-Puncture Time (DPT) | ime from the arrival of stroke patient in emergency to groin puncture. | 24 hours | 
| Onset-to-recanalization time | Time from symptom onset to the beginning of recanalization (recanalization defined as expanded TICI scale≥2b). | 24 hours | 
| Door-to-Recanalization Time (DRT) | Time from the arrival of stroke patient in emergency to the beginning of recanalization (recanalization defined as expanded TICI scale≥2b). | 24 hours | 
| Puncture-to-recanalization time | Time from groin puncture to recanalization (recanalization defined as expanded TICI scale≥2b). | 24 hours |
