  • Ability to comply with study follow-up.

You may not qualify if:

  • Concomitant other diseases, including systemic vasculitis, neurofibroma, meningitis, sickle cell disease, down's syndrome, and previous basilar radiotherapy.
  • Patients with cardiogenic embolism, including a history of atrial fibrillation, valvular disease or cardiac valve replacement.
  • Patients are allergic to the contrast agents.
  • Patients are treated with direct, indirect, or combined revascularization depending on the presentation.
