Carotid Artery Disease: Assessment and Stroke Risk

What Is Carotid Artery Disease?

Carotid artery disease occurs when fatty deposits (plaques) clog the carotid arteries—the blood vessels that deliver blood to your brain. This condition is a major cause of stroke.

Why It Matters

The carotid arteries supply oxygen-rich blood to your brain. When these arteries become narrowed or blocked:

• Blood flow to the brain is reduced
• Pieces of plaque can break off and travel to smaller vessels
• A stroke can occur, causing permanent brain damage or death

Warning Signs

Transient Ischemic Attack (TIA) - "Mini Stroke"

• Sudden numbness or weakness in face, arm, or leg (especially one side)
• Confusion or trouble speaking
• Vision problems in one or both eyes
• Dizziness or loss of balance
• Severe headache with no known cause

A TIA or sudden stroke-like symptom is an emergency. Call 112 in Kuwait or go to the nearest emergency department immediately.

Asymptomatic Disease

Carotid disease can exist without symptoms, but carotid ultrasound is not recommended as routine screening for every asymptomatic adult. A clinician should decide whether testing is appropriate after considering the clinical question, examination findings, and medical history.

Risk Factors

• High blood pressure
• High cholesterol
• Diabetes
• Smoking
• Obesity
• Family history of stroke
• Age over 65
• Sedentary lifestyle

Carotid Duplex Ultrasound Assessment

A carotid duplex ultrasound is a non-invasive test that:

• Shows the structure of your carotid arteries
• Measures blood flow velocity
• Detects plaque buildup
• Identifies narrowing (stenosis)

When Might a Clinician Consider It?

• After a stroke or TIA, when requested as part of medical assessment
• For a carotid bruit or another relevant abnormal examination finding
• To follow known carotid plaque, narrowing, or a previous carotid procedure
• For selected cardiovascular or vascular conditions when the result could change management
• For another specific referral question determined by the treating clinician

Prevention Strategies

1. Control blood pressure
2. Manage cholesterol levels
3. Quit smoking
4. Maintain healthy weight
5. Exercise regularly
6. Manage diabetes
7. Eat a heart-healthy diet

Carotid Assessment at Vascular Lab Kuwait

If your clinician has requested a carotid duplex examination or follow-up of known carotid disease, Vascular Lab Kuwait can coordinate the requested scan and document the findings for medical review.

Do not wait for an outpatient appointment if new stroke-like symptoms occur. Call 112 in Kuwait or go to the nearest emergency department immediately.
