The 2014 AHA/ASA guidelines state the following for patients with stroke or TIA due to 50-99% stenosis of a major intracranial artery: [46]

  • Aspirin 50-325 mg/day, rather than warfarin, is recommended

  • Maintenance of blood pressure below 140/90 mm Hg and total cholesterol below 200 mg/dL is recommended

  • Extracranial or intracranial bypass surgery is not recommended

  • Angioplasty and stent placement are investigational and of unknown utility
