A Multicenter Registry of Endovascular Treatment for Acute Ischemic Stroke.

The OCIN-AIS-EVT REGISTRY is a prospective, multicenter, blinded outcome evaluation, observational trial, and aims to determine the functional outcomes and safety of endovascular treatment for AIS, due to vessel occlusion in anterior and posterior circulation, in routine clinical practice.

The primary endpoint is functional outcome, defined as a shift (improvement) in scores on the modified Rankin scale (mRS) at 90 days (±7 days).

Inclusion Criteria:

1. Acute ischemic stroke caused by anterior or posterior circulation vessel occlusion confirmed by computed tomography angiography (CTA) or magnetic resonance angiography (MRA) or digital subtraction angiography (DSA)
2. Undergo intravascular therapy (i.e. access to a cath lab and an arterial puncture)
3. The patient or his/her legal representative agreed to participate in the study and has signed the informed consent.

Exclusion Criteria:

1) No exclusion criteria

All acute ischemic stroke patients receiving endovascular treatment

Data can be shared with bona fide researchers after the publication of the main results, based on a submitted protocol to Oriental Collaboration group on Emerging Advanced therapy for Neurovascular diseases Consortium.

Data sharing will be available from 12 months after the publication of the main results.

1. The data sharing will be only for the purposes of health and medical research and within the constraints of the consent under which the data were originally gathered.
2. The Custodian of the Collection will not consider any Proposals for data sharing that unblind, or potentially unblind, randomised comparisons in active / ongoing trials.
3. Requesters should be employees of a recognised academic institution, health service organisation, commercial research organisation or from the pharmaceutical industry. Requesters must have experience in medical research.
4. Requesters must be able to demonstrate through their peer review publications in the area of interest their ability to carry out the proposed use of the requested dataset from a Collection.
5. The Requesters must not have a conflict of interest that may potentially influence their interpretation of any analyses
