For patients with acute ischemic stroke (AIS) with anterior circulation proximal large vessel occlusion (LVO), mechanical thrombectomy (MT) reduces disability in patients when it is performed within 6 h of the time the patients with a stroke were last known to be healthy and up to 24 h after stroke onset in patients selected using brain perfusion imaging. For patients with acute ischemic stroke (AIS) with posterior circulation large vessel occlusion, MT could be benefit the patients when performed within 24 hours since onset. This is a multicenter registration study of the AIS-LVO treated with endovascular treatment. This study will record the patients' demographic and clinical data, image data, procedure of neurointervention and outcomes in 3 months. Samples of thrombus and serum will be collected and stored for later analysis.
The goal of this observational cohort study is to learn about the outcome of acute ischemic stroke patients subjected to endovascular treatment.
