What is a carotid endarterectomy?

  • A carotid endarterectomy is an operation to remove fatty deposits (plaques) from your carotid artery. This improves blood flow and helps prevent stroke.
  • You have 2 carotid arteries in your neck that carry blood to your brain, face and neck. If they become narrowed, you have a higher chance of having a stroke or transient ischaemic attack (TIA).
  • The operation usually takes 1 to 2 hours and you may need to stay in hospital for a few days afterwards. You’ll have a scar on your neck that will usually fade and disappear after a few months.
  • If both of your carotid arteries are narrowed, you may need 2 separate operations a few weeks apart.
