Carotid Arteries: Causes, Symptoms, and Treatment

What kind of doctor treats Carotid Arteries?
A primary care doctor often checks for it first. A neurologist, a doctor who treats brain and nerve problems, or a vascular surgeon, a doctor who operates on blood vessels, may also help manage it. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What are the carotid arteries?
The carotid arteries provide part of the main blood supply to your brain. They are located on each side of your neck, and you can feel their pulse under your jawline. Carotid artery disease is when these arteries become narrowed or blocked. This usually happens when fatty material called plaque builds up inside them, a process called atherosclerosis or hardening of the arteries. The plaque may slowly narrow the artery, or it may cause a clot that blocks blood flow and leads to a stroke.
Symptoms
At early stages, you may not have any symptoms. The first sign may be a stroke or a transient ischemic attack (TIA), a temporary drop in blood flow to the brain. It causes no lasting damage. Symptoms of stroke and TIA include:
- Blurred vision or vision loss.
- Confusion and problems with thinking, reasoning, and memory.
- Loss of sensation in one part of your body.
- Problems with speech and language, including loss of speech.
- Weakness in one part of your body.
TIA symptoms start suddenly, last only a few minutes to an hour or two, and then go away. A TIA is a medical emergency, so call 911 even if the symptoms go away. It is a warning that a stroke may happen soon if nothing is done to prevent it.
Causes and who gets it
Plaque builds up inside the arteries over time. Risk factors for narrowing or blockage include:
- Smoking.
- Diabetes, high blood pressure, and high cholesterol and triglycerides.
- Older age.
- Family history of stroke or blood vessel disorder.
- Alcohol use and recreational drug use.
- Trauma to the neck, which may cause a tear in the carotid artery.
- Radiation therapy to the neck.
How doctors diagnose it
Your provider will do a physical exam and may use a stethoscope to listen to blood flow in your neck. An abnormal sound called a bruit may be a sign of carotid artery disease. You may have blood tests for cholesterol and blood sugar. An ultrasound of the carotid arteries, called a carotid duplex ultrasound, shows how well blood is flowing. Imaging tests may include a CT angiogram or an MR angiogram. Another test is a transcranial Doppler ultrasound. It tracks blood flow in the brain.
Treatment
Treatment options include:
- Blood-thinning medicines such as aspirin or clopidogrel to lower your risk for stroke.
- Medicines and diet changes to lower your cholesterol or blood pressure.
- Regular checkups without other treatment, for mild narrowing.
Two procedures can open a narrowed artery. Carotid endarterectomy is surgery that removes the plaque. Carotid angioplasty and stenting opens the artery and places a tiny wire mesh tube (stent) to keep it open. Never stop taking medicines or take less medicine without talking to your provider first.
When to see a doctor
Go to the emergency room or call 911 as soon as stroke or TIA symptoms start, even if they go away. These include weakness on one side, speech problems, vision loss, or confusion. The sooner you receive treatment, the better your chance for recovery. With a stroke, every second of delay can cause more brain injury.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can check your blood pressure and cholesterol, listen for a bruit, and refer you to a neurologist or vascular surgeon. They can also make sure you are healthy enough to exercise before you start.
Common questions
What is a TIA?
A TIA, or transient ischemic attack, happens when a blood clot briefly blocks a vessel to the brain. It causes the same symptoms as a stroke but does not cause lasting damage. It is a warning sign that a stroke may happen in the future if nothing is done to prevent it. Call 911 right away, even if the symptoms go away.
Can carotid artery disease be prevented?
You can lower your risk by quitting smoking, eating a healthy low-fat diet, exercising most days, limiting alcohol, and not using recreational drugs. Getting your cholesterol and blood pressure checked and treated also helps.
What is a carotid bruit?
A bruit is an abnormal sound a provider hears through a stethoscope over the artery in your neck. It may be a sign that blood flow is disturbed and that carotid artery disease is present.
Do people recover from carotid stroke?
Some people who have a stroke recover most or all of their functions. About one half of people who have a stroke have long-term problems, and some die of the stroke or its complications.
