Carotid Artery Disease

Carotid artery disease can raise your risk of stroke. Find out how early detection, skilled care, and healthy lifestyle choices can safeguard your brain and heart health. This can lead to a better quality of life.

What is Carotid Artery Disease?

Carotid artery disease happens when the main arteries in the neck that supply blood to the brain, known as the carotid arteries, become narrowed or blocked. This usually occurs because of atherosclerosis, which is a buildup of fatty deposits, or plaque. This condition greatly raises the risk of stroke.

Causes of Carotid Artery Disease

Carotid artery disease is usually caused by atherosclerosis, but contributing factors include:

• High blood pressure (hypertension)
• High cholesterol and lipid levels
• Smoking
• Diabetes
• Obesity
• Sedentary lifestyle
• Family history of vascular disease
• Advanced age
  

Symptoms

Carotid artery disease often develops quietly until it reaches a severe stage. Warning signs may include:

• Sudden numbness or weakness in the face or limbs, especially on one side.
• Difficulty speaking or understanding speech.
• Sudden vision problems in one or both eyes.
• Dizziness or loss of balance.
• Severe headache with no known cause.
• Transient ischemic attacks (TIAs): temporary “mini-strokes” that last a few minutes to hours.

If you experience these symptoms, seek emergency care immediately.

Diagnosis

Diagnosing carotid artery disease typically includes:

• Physical exam, where the doctor listens for carotid bruits with a stethoscope  
• Carotid ultrasound to check blood flow and plaque buildup  
• CT angiography (CTA) or MR angiography (MRA) for detailed images  
• Cerebral angiogram in certain cases  
• Blood tests to evaluate risk factors 

Treatment Options

The goal of treatment is to lower the risk of stroke and restore normal blood flow. Treatment options may include: 

• Medications: antiplatelet agents like aspirin, cholesterol-lowering drugs such as statins, and management of blood pressure.  
• Lifestyle changes that can slow disease progression.  
• Carotid endarterectomy (CEA): surgically removing plaque from the artery.  
• Carotid artery stenting (CAS): inserting a stent to keep the artery open.
  

Lifestyle Management

Adopting a lifestyle that supports healthy blood vessels can slow down or prevent the progression of carotid artery disease:

• Follow a heart-healthy, low-fat diet
• Stop smoking and avoid secondhand smoke
• Exercise regularly, as advised by your doctor
• Maintain a healthy weight
• Keep blood pressure, cholesterol, and blood sugar under control.
• Limit alcohol consumption
• Take medications consistently and go to regular check-ups
