Study population: all acute stroke patients with the clinical diagnosis of acute ischemic stroke, eligible for IVT and IVT initiated within 4.5 hours after stroke onset, Age \>18 years

Brief summary: The German Stroke Registry (GSR) Endovascular Treatment is an academic, independent, prospective, multicentre, observational registry study. Consecutive patients treated with endovascular stroke treatment will be enrolled in German stroke centers. Patients receive regular care and data will be collected as part of clinical routine. Baseline clinical and procedural information as well clinical follow-up information during in-hospital stay, and up to 90 days of stroke onset are collected. Data collected include demographics, National Institute of Health Stroke Scale (NIHSS) on admission, pre-treatment ASPECTS, information on timing and success of interventional treatment, procedural complications, intracranial hemorrhage, and functional outcome.


Eligibility criteria: Inclusion Criteria:

* Clinical diagnosis of acute ischemic stroke
* Eligible for intravenous thrombolysis (IVT) and IVT initiated within 4.5 hours after stroke onset
* Confirmed diagnosis of persistent occlusion of terminal carotid artery, middle cerebral artery (M1 or M2), or basilar artery consistent with symptoms
* Age \>18 years
* Ethic approval in process

Exclusion Criteria: none
