Carotid Artery (Disease) Stenosis

Carotid artery stenosis (also called carotid artery disease) occurs when fatty material and atherosclerotic plaques accumulate on the inside of the artery wall, which reduces the flow of blood to the brain. Each of us has two common carotid arteries, one on either side of the neck. Each divides into the external and internal carotid arteries.

Internal carotid arteries deliver oxygen-rich blood from the heart to the brain. The external carotid arteries supply oxygen-rich blood to your scalp, neck and face.

Carotid Artery Stenosis Symptoms

The symptoms of carotid artery stenosis may include:

  • Dizziness
  • Numbness in one side of your face
  • Numbness or weakness in your limbs
  • Sudden vision problems in one or both eyes
  • Sudden weakness or numbness in the face, arms, or legs (usually on one side of the body)
  • Sudden, severe headache
  • Trouble speaking (garbled speech) or understanding
