Acute ischemic stroke (AIS) is one of the main causes of disability and loss of quality adjusted life years. This study is to analyze whether endovascular therapy (EVT) in addition to best medical treatment (BMT) reduces the degree of disability and dependency in daily activities after a Medium Vessel Occlusion (MeVO) stroke compared to BMT alone.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Acute ischemic stroke
* Treatment (arterial puncture) can be initiated 2.1. Within 6 hours of last seen well (LSW) OR 2.2. Within 6 to 24 hours of LSW AND
* CT Criteria: Evidence of a hypoperfusion-hypodensity mismatch (Absence of hypodensity on the noncontrast CT within ≥ 90% of the area of the hypoperfused lesion on perfusion CT)
* MRI Criteria: Evidence of a diffusion-hyperintensity mismatch (Absence of hyperintensity on fluid-attenuated inversion recovery (FLAIR) imaging within ≥ 90% of the area of the diffusion weighted imaging(DWI) lesion)
* Isolated medium vessel occlusion (i.e. an occlusion of the co-/non-dominant M2, the M3/M4 segment of theMCA, the A1/A2/A3 segment of the ACA or the P1/P2/P3 segment of the PCA) confirmed by CT or MRIAngiography
* National Institute of Health Stroke Scale (NIHSS) Score of ≥ 4 points or symptoms deemed clearly disabling by treating physician (i.e. aphasia, hemianopia, etc.)
* Informed Consent as documented by signature or fulfilling the criteria for emergency consent/ deferral consent
* Agreement of treating physician to perform endovascular procedure
Exclusion Criteria:
* Acute intracranial haemorrhage
* Patient bedridden or presenting from a nursing home
* In-Hospital Stroke
* Known (serious) sensitivity to radiographic contrast agents, nickel, titanium metals or their alloys
* Foreseeable difficulties in follow-up due to geographic reasons (e.g. patients living abroad)
* Pregnancy or lactating women. A nega…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
