Arterial Condition

Carotid Artery Disease

Carotid artery disease is a leading cause of stroke. At Vascular Surgical Associates, our experienced vascular surgeons use advanced diagnostic imaging and proven surgical techniques to identify carotid blockages early and reduce your stroke risk.

What is Carotid Artery Disease?

Carotid artery disease, also called carotid artery stenosis, occurs when the carotid arteries—the two major blood vessels on either side of your neck that supply blood to your brain—become narrowed or blocked by a buildup of fatty deposits known as plaque. This process, called atherosclerosis, develops gradually over many years and progressively restricts blood flow to the brain.

The greatest danger of carotid artery disease is stroke. When plaque narrows the carotid artery significantly, it can either restrict blood flow to the brain or break apart, sending fragments (emboli) into smaller brain arteries where they cause a blockage. Stroke is the fifth leading cause of death in the United States and a major cause of long-term disability, making early detection and treatment of carotid disease critically important.

At Vascular Surgical Associates, our 11 board-certified vascular surgeons specialize in the evaluation and management of carotid artery disease. With our ICAVL-accredited vascular laboratory and decades of surgical experience dating back to 1986, we provide comprehensive carotid care from initial screening through surgical intervention and long-term follow-up across all 7 of our metro Atlanta locations.

Signs & Symptoms

Carotid artery disease frequently develops without any noticeable symptoms. In many cases, the first sign is a stroke or transient ischemic attack (TIA), often called a mini-stroke. A TIA produces stroke-like symptoms that resolve within minutes to hours, but it serves as a serious warning that a full stroke may follow. Symptoms to watch for include:

Sudden Weakness or Numbness
Unexpected weakness, numbness, or tingling on one side of the body, particularly in the face, arm, or leg, is a hallmark sign of impaired blood flow to the brain.
Vision Changes
Sudden blurred or lost vision in one or both eyes, or a temporary dark curtain descending over one eye (amaurosis fugax), may indicate reduced blood supply to the visual cortex.
Difficulty Speaking
Slurred speech, difficulty finding words, or trouble understanding others can occur when blood flow to the brain's language centers is disrupted.
Severe Headache
A sudden, severe headache with no known cause—especially when accompanied by other neurological symptoms—may signal a stroke or TIA.
Dizziness or Loss of Balance
Sudden dizziness, loss of coordination, or difficulty walking can occur when blood flow to the brain is compromised by a narrowed carotid artery.

Risk Factors

High Blood Pressure
Hypertension places excessive force on the arterial walls, accelerating damage to the delicate lining of the carotid arteries and promoting plaque formation.
Smoking
Tobacco use irritates and damages the inner lining of the arteries, raises blood pressure, and increases the tendency of blood to clot—all of which accelerate carotid disease.
Diabetes
Diabetes damages blood vessels throughout the body and significantly increases the rate of atherosclerosis, making carotid stenosis more common and more aggressive.
High Cholesterol
Elevated levels of LDL (bad) cholesterol contribute directly to the buildup of fatty plaques within the carotid arteries, progressively narrowing the vessel.
Obesity
Excess body weight is closely linked with hypertension, diabetes, and high cholesterol—all of which independently contribute to carotid artery disease development.
Family History & Age
A family history of atherosclerosis or stroke increases your risk. The likelihood of carotid disease also rises with age, particularly after 55, as arterial walls stiffen and accumulate damage.

Diagnosis at VSA

Vascular Surgical Associates uses a comprehensive approach to diagnosing carotid artery disease, beginning with a thorough physical examination. Your vascular surgeon may detect a bruit—an abnormal whooshing sound—when listening to the carotid arteries with a stethoscope, which can be an early indicator of narrowing.

The primary diagnostic tool is a carotid duplex ultrasound, a painless, non-invasive imaging study performed in our ICAVL-accredited vascular laboratory. This test uses sound waves to create detailed images of the carotid arteries, measuring the degree of narrowing and assessing plaque characteristics. The ICAVL accreditation of our lab ensures that every study meets the highest standards for accuracy and reproducibility.

When additional detail is needed—particularly before surgical planning—we may utilize CT angiography (CTA) or magnetic resonance angiography (MRA). These advanced imaging studies provide highly detailed three-dimensional views of the carotid arteries and surrounding anatomy, helping our surgeons determine the optimal treatment approach for your specific situation.

Treatment Options

Treatment for carotid artery disease is guided by the degree of stenosis, whether you have experienced symptoms (such as a TIA or stroke), and your overall health profile. Our goal is to reduce your stroke risk through the most effective and least invasive means possible.

1
Lifestyle Modifications
For patients with mild carotid stenosis, managing underlying risk factors is the first line of defense. This includes smoking cessation, adopting a heart-healthy diet low in saturated fat and sodium, regular physical activity, weight management, and strict blood sugar control for diabetic patients.
2
Medical Therapy
Medications are a cornerstone of carotid disease management. Antiplatelet agents such as aspirin or clopidogrel help prevent blood clots from forming on the plaque surface. Statins lower cholesterol and may stabilize vulnerable plaques. Antihypertensive medications reduce the stress on arterial walls. These are often used in combination for optimal protection.
3
Carotid Endarterectomy (CEA)
CEA is the gold-standard surgical treatment for significant carotid stenosis. Through an incision in the neck, the surgeon opens the carotid artery, carefully removes the accumulated plaque, and repairs the vessel. This well-established procedure has been shown to dramatically reduce the risk of stroke in patients with severe carotid narrowing. Our surgeons perform CEA routinely with excellent outcomes and low complication rates.
4
Carotid Artery Stenting (CAS)
CAS is a minimally invasive alternative to endarterectomy in which a catheter is threaded from the groin to the carotid artery. A balloon is inflated to widen the narrowed area, and a small mesh stent is placed to hold the artery open. An embolic protection device is used during the procedure to capture any debris and prevent it from reaching the brain. CAS may be recommended for patients who are at higher surgical risk for CEA or who have certain anatomical considerations.

Frequently Asked Questions

Yes, carotid artery disease is often called a “silent” condition because many people have significant narrowing without any symptoms at all. This is why screening is so important, especially if you have risk factors such as high blood pressure, diabetes, smoking history, or elevated cholesterol. A simple, painless carotid duplex ultrasound can detect the disease before symptoms or a stroke occurs.

A transient ischemic attack (TIA) produces the same symptoms as a stroke—sudden weakness, speech difficulty, vision loss—but the symptoms resolve on their own, typically within minutes to hours, without causing permanent brain damage. However, a TIA is an urgent warning sign: approximately 10 to 15 percent of people who experience a TIA will go on to have a major stroke within 90 days if the underlying cause is not treated. If you experience any TIA symptoms, seek immediate medical attention.

Most patients spend one to two nights in the hospital following carotid endarterectomy and can return to normal daily activities within one to two weeks. Driving is typically permitted after two weeks, and full recovery usually occurs within four to six weeks. Our surgical team will provide detailed post-operative instructions and schedule follow-up appointments to monitor your healing and ensure optimal outcomes.

For patients who have experienced symptoms (TIA or stroke), surgery is generally recommended when the carotid artery is 50 percent or more narrowed. For patients without symptoms, surgical intervention is typically considered when the narrowing reaches 60 to 80 percent, depending on the patient's overall health, plaque characteristics, and life expectancy. Your vascular surgeon will discuss the specific threshold that applies to your situation based on the latest evidence-based guidelines.
