Conditions & Diseases

Carotid Artery Disease

The carotid arteries are the large arteries on each side of the neck that supply blood to the head and brain. Carotid artery disease involves a buildup of fatty deposits or “plaque” that can narrow and block blood flow through the arteries, possibly leading to a stroke. Nearly 700,000 people in the United States experience a stroke each year; 200,000 of them are repeat strokes.

Signs & symptoms

Carotid artery disease may never show signs until a stroke has occurred. Call 911 immediately if you experience any signs or symptoms of a stroke, which may include:

  • Partial loss of vision in one eye
  • Weakness, tingling or numbness in one arm and/or leg
  • Temporary loss of control of movement in one arm and/or leg
  • Inability to pronounce words or speak clearly
  • Unsteadiness, vertigo, double vision or sudden falls
  • Difficulty swallowing
  • Temporary memory loss
  • Vertigo
  • Loss of balance
  • Personality or mood changes
  • Drowsiness or loss of consciousness
  • Uncontrollable eye movements or eye drooping
Risk factors
  • High blood pressure
  • High cholesterol
  • Smoking
  • Diabetes
  • Obesity
  • Sleep apnea
  • Family history
  • Age
Diagnosis

Diagnosis of carotid artery disease typically includes a medical evaluation and review of family history and risk factors. Testing may include:

  • Ultrasound
  • CT or MRI
  • CT angiography or MR angiography
Treatment

Minimally-invasive treatment options include:

  • Clot-busting medications delivered through catheters to the affected area
  • The insertion of a small wire tube (stent) to help clear and widen the affected arteries
  • Surgical removal of the plaque blocking the arteries
