To investigate the real situation of assessment, diagnosis and treatment of acute ischemic stroke patients with endovascular therapy.

Prospective Registry Study of Endovascular Treatment for Acute Ischemic Stroke Patients is an academic,independent, pragmatic , prospective, multicenter, observational registry study. The acute ischemic stroke patients undergone endovascular therapy will be enrolled in stroke centers. Baseline information and clinical follow-up information at 90 days of stroke onset are collected. Data collected include demographics, comorbidities, pathogenesis, blood pressures, stroke severity on admission, time intervals, reperfusion condition, and functional outcome, et al. The study aims to investigate the real situation of assessment, diagnosis and treatment of acute ischemic stroke patients with endovascular therapy.
