Carotid bruit is also known as or subsumes Asymptomatic bruits, Cervical murmur, and Symptomatic bruits. -ed.

Dr. Seemant Chaturvedi, Professor of Neurology and Director of the Comprehensive Stroke Program at Wayne State University, summarizes new information on management of patients with asymptomatic carotid bruits. New information on the risk of cognitive worsening with carotid stenosis is provided. New studies showing a reduced rate of stroke with modern medical therapy are also included. Finally, new clinical trials that will soon be launched for this patient population are described.

Key Points

  • Asymptomatic carotid stenosis is present in 4% to 6% of subjects age 65 years and older.
  • Asymptomatic carotid stenosis increases the stroke risk to a slight degree, but the risk is much lower compared to symptomatic patients.
  • Carotid endarterectomy can be useful for highly select patients if the major complication rate is low (less than 3%) and if the patient has at least a 5-year life expectancy.
  • Intensive medical therapy is needed for all patients with carotid stenosis.
