The Acute Ischemic Stroke Registry for Endovascular Treatment (AIS-EVT) is an academic, prospective, multicenter, observational registry study. Consecutive stroke patients treated with endovascular treatment 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.

Inclusion Criteria:

1. Diagnosis of acute ischemic stroke;
2. Imaging confirmed intracranial large vessel occlusion: intracranial internal carotid artery (ICA), middle cerebral artery (MCA M1/M2), anterior cerebral artery (ACA A1/A2), basilar artery (BA), vertebral artery (VA V4), and posterior cerebral artery (PCA P1);
3. Initiation of any type of endovascular treatment, including intra-arterial thrombolysis, mechanical thrombectomy, aspiration, angioplasty, and stenting;
4. Verbal and written informed consent was provided at the time of admission by patients or their legal authorized representatives.

Exclusion Criteria:

No evidence of large vessel occlusion on digital subtraction angiography.

Acute ischemic stroke patients with large vessel occlusion receiving endovascular treatment.
