Brief Summary
Stroke occurs when a blood clot causes a blockage in a blood vessel (artery) within the brain. This type of stroke is called an ischemic stroke and carries a high risk of disability or death. Stroke must be treated very fast. Any delay of even 10 minutes can result in the difference between an independent and a disabled outcome, and in some cases between life and death. Endovascular therapy (EVT) or Thrombectomy is a procedure to remove the blood clot (thrombus) from a blood vessel to reopen it (recanalization). Patients are likely to benefit from a thrombectomy procedure when it is performed in a larger blood vessel. Currently it is not known if thrombectomy procedure will benefit the patients presenting with the stroke that has been caused by a blood clot in a medium sized blood vessel (medium vessel occlusion, MeVO). This trial will enrol patients diagnosed with acute stroke due to a clot in the medium sized vessel. The patients will be randomized within 12 hours of their symptom onset to either standard of care or standard of care plus thrombectomy procedure. The participation will last for 12 months Escape MeVO coordinating centre is located at the University of Calgary. There will be up to 75 sites. We will be recruiting a total of 530 patients.

best medical care
PLACEBO COMPARATORAll patients will receive the best standard of medical care according to modern acute stroke care guidelines All patients including the ones in control arm will receive the best standard of medical care according to modern acute stroke care guidelines. The model will be the Canadian best practices guidelines for acute stroke care. These are very similar to the guidelines of the American Stroke Association and the European Stroke Organization. All participants are expected to be admitted to hospital as part of routine standard of care.It is expected that all participants will undergo a routine work-up for the mechanism of their stroke and be treated appropriately and definitively.
endovascular thrombectomy
EXPERIMENTALAll participants will receive the best standard of medical care according to modern acute stroke care guidelines. In the intervention/experimental arm, participants will be treated with endovascular thrombectomy with a Solitaire device (Medtronic) as the first line approach. The trial mandates that the first attempt is performed with a Solitaire X device (3mm, 4mm or 6mm diameter devices; Medtronic). The remaining treatment technique is left to the discretion of the treating neurointerventionalist. Secondary devices may be used if success is not achieved after use of the first device.
Interventions
minimally invasive endovascular surgery for mechanical removal of occluding intracranial thrombus
Stanadard medical care wil involve use of thrombolytic drugs, Blood pressure management, use of antiplatelet or anti coagulant drugs
Eligibility Criteria
You may qualify if:
- Acute ischemic stroke clinically eligible for immediate EVT
- Age ≥18 years at the date of randomization
- Time from onset (or last-seen-well) to randomization \<12 hours
- Disabling stroke defined as follows:
- baseline National Institutes of Health Stroke Scale (NIHSS) score \>5 at the time of randomization
- NIHSS 3-5 with disabling deficit (eg. hemianopia, aphasia, loss of hand function) as determined by the attending physician in context of the patient's life situation
- Confirmed symptomatic and endovascularly treatable MeVO based on neurovascular non-invasive imaging (mCTA or MRA), at one or more of the following locations: M2 or M3 segment, A2 or A3 segment, P2 or P3 segment1.
- Clinical deficit commensurate with MeVO occlusion location
- Signed informed consent, two-physician consent, or deferral of consent where approved
You may not qualify if:
- ASPECTS ≤ 5
- The following depend on the imaging modality of the participating site:
- a. NCCT + mCTA
- Well demarcated hypodensity in the majority of the brain parenchyma supplied by the occluded vessel or absence of collaterals in the affected territory on the delayed phases of the mCTA OR 9b. NCCT + (m)CTA + CTP\*\*
- Diffusion restriction in the majority of the brain parenchyma supplied by the occluded vessel
- if MR perfusion is performed: lack of core:penumbra mismatch 10) Any evidence of intracranial hemorrhage on qualifying imaging 11) Patients living in a nursing home or requiring daily nursing care or assistance with activities of daily living.
- \) Patient has a major co-morbid illness, such as severe dementia, advanced cancer, advanced heart failure etc. such that they are unlikely to be able to complete follow-up or they are unlikely to achieve the primary outcome due to the underlying illness (rather than the stroke or its treatment).
- \) Pregnancy: female with positive urine or serum beta human chorionic gonadotropin (β-hCG) test 14) Participation in another clinical therapeutic intervention trial
