Eligibility Criteria

Eligible

You may qualify if you...

  • Patient is 30 to 85 years of age, inclusive.
  • For symptomatic group: acute infarct on MRI compatible with artery-to-artery embolism, intracranial atherosclerotic stenosis 60% or greater, and microembolic signals detected by TCD.
  • No contraindications for proposed imaging tests.
  • Understands the study purpose and has provided informed consent.
  • For asymptomatic group: high-grade intracranial stenosis over 60% on MR angiography without infarct in the corresponding vascular territory and no microembolic signals on TCD.
Not Eligible

You will not qualify if you...

  • Stroke cause uncertain or unrelated to intracranial atherosclerosis, such as cardioembolism, Moyamoya disease, or small vessel disease.
  • Tandem stenosis over 50% at proximal internal carotid artery.
  • Bleeding risk conditions including active peptic ulcer, major systemic hemorrhage within 30 days, low platelets (under 100 x 10^9/L), or coagulopathy (INR over 1.5).
  • Medical conditions preventing adherence to the study protocol or completion of the study.
