Carotid artery disease occurs when the main blood vessels to the brain develop a buildup of plaque caused by atherosclerosis. Some plaque in the carotid arteries is normal with age. Too much plaque build up can cause a stroke.  

Risk Factors

You are at a higher risk for stroke due to carotid artery disease if you experience these conditions:

  • High blood pressure or cholesterol
  • Irregular heartbeat
  • Diabetes
  • Are a smoker
  • Had a stroke or have a family history of stroke

Symptoms

The main warning signs for a stroke include:

  • Sudden weakness
  • Slurring of speech
  • Paralysis of an arm or leg
  • Dizziness and blurry eyesight

Call 911 immediately if you have these symptoms.

Treatment

Most cases of carotid artery disease do not require treatment. But when plaque causes a blockage of 60 to 70% or more, or causes mini-strokes, treatment may be required.

A carotid endarterectomy (CEA) clears up a larger percentage of the plaque. After the CEA, more than 90% of patients are free from stroke and have normal carotid arteries for the rest of their lives.
