Carotid Stenosis

The carotid artery in the neck is main source of blood supply to the brain. As people age, fatty deposits may build up, causing blockage, or stenosis. This build-up is sometimes referred to as “hardening of the arteries” and is sometimes expressed as a percentage of the normal size of the artery.

Carotid stenosis can cause a stroke. Symptoms may include:

  • Light headedness or dizziness
  • slurred speech
  • blurred vision
  • numbness or muscle weakness
  • paralysis of the face or arms and legs, especially on one side of the body.

Carotid stenosis may be surgically treated by a procedure known as carotid endarterectomy, which greatly reduces the risk of a stroke. It is especially helpful for patients with stenosis above 70%.
