You may be able to join if

  • Posterior circulation acute ischemic stroke within 24-72 hours from symptom onset/last seen well (except for isolated vertigo), where patient is...

  • Known hemorrhagic diathesis, coagulation factor deficiency, or oral anticoagulant therapy with INR \> 3.0.
  • Baseline platelet count \< 50000/µL.
  • Baseline blood glucose of \ 400mg/dl.
  • Severe, sustained hypertension (SBP \> 220 mm Hg or DBP \> 110 mm Hg) NOTE: If the blood pressure can be successfully reduced and maintained below...

  • Unlikely to be available for 90 days follow-up (e.g. no fixed home address, visitor from overseas).
  • Any other condition that, in the opinion of the investigator will pose a significant hazard to the subject if participating in the trial. Neuroimaging criteria

  • people with occlusions in both anterior and posterior circulation.
  • Evidence of intracranial tumor (except small meningioma).
