A carotid ultrasound can show whether plaque buildup has narrowed one or both of your carotid arteries and reduced blood flow to your brain. If plaque has narrowed your carotid arteries, you may be at risk of having a stroke. That risk depends on how much of your artery is blocked and how much blood flow is restricted.

Why would my doctor order a carotid ultrasound?
A carotid ultrasound is performed to test for narrowed carotid arteries, which increase the risk of stroke. Carotid arteries are usually narrowed by a buildup of plaque — made up of fat, cholesterol, calcium and other substances that circulate in the bloodstream.
What are normal results from a carotid ultrasound?
A normal result means there is no problem with the blood flow in the carotid arteries. The artery is free of any significant blockage, narrowing, or other problem.
How accurate is an ultrasound of the carotid arteries?
Carotid duplex sonography showed 93.5% sensitivity and 92.9% specificity for detection of unstable carotid plaque. The presence of carotid plaque ulceration is another independent risk factor for stroke than echogenicity and structure.
How long does it take to get results from carotid ultrasound?
It may take 3 to 4 days before you know the results of your test. What is a Carotid Artery Duplex? A Carotid Artery Duplex is an ultrasound test that uses high frequency sound waves (ultrasound) to show how well blood is flowing through the carotid arteries. The carotid arteries are located in the neck.
What are the symptoms of blocked carotid arteries?
Carotid Artery Blockage Symptoms
- Blurred vision or vision loss.
- Memory loss.
- Numbness or weakness in part of your body or one side of your body.
- Problems with thinking, reasoning, memory and speech.
Can you feel clogged arteries in your neck?
The plaque or clot can travel through the bloodstream and get stuck in one of your brain’s smaller arteries. Carotid artery disease often does not cause symptoms until the blockage or narrowing is severe. One sign may be a bruit (whooshing sound) that your doctor hears when listening to your artery with a stethoscope.
What percentage of carotid artery blockage requires surgery?
Surgery is the best option for symptomatic patients with 70% to 99% blockage in the carotid artery. However, it can also be considered for patients with 50% to 69% blockage. Doctors agree that surgery is the most effective option for patients with moderate to severe carotid stenosis.
What is the treatment for a blockage in the carotid artery?
Carotid endarterectomy, the most common treatment for severe carotid artery disease. After making an incision along the front of your neck, the surgeon opens the affected carotid artery and removes the plaques. The artery is repaired with either stitches or a graft.

Can ultrasound show clogged arteries?
Sometimes the only way to know if your arteries are clogged is to undergo a screening test such as a carotid Doppler ultrasound, which can check for blockages that might put you at risk of a stroke.
How long can you live with a blocked carotid artery?
In other words, most patients who have carotid stenosis without symptoms will not have a stroke and this risk can be further reduced by surgery. To benefit from surgery, asymptomatic patients should have a narrowing of more than 70% and a life expectancy of at least 3-5 years.
How serious is a blocked carotid artery?
If the narrowing of the carotid arteries becomes severe enough that blood flow is blocked, it can cause a stroke. If a piece of plaque breaks off it can also block blood flow to the brain. This too can cause a stroke.
When does a blocked carotid artery need surgery?
Surgery to remove the buildup in your carotid artery may be done if the artery is narrowed by more than 70%. If you have had a stroke or temporary brain injury, your provider will consider whether treating your blocked artery with surgery is safe for you.
What side of neck is carotid artery?
There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions: The internal carotid artery supplies blood to the brain. The external carotid artery supplies blood to the face and neck.
What does an aneurysm in the neck feel like?
In addition to a severe headache, common signs and symptoms of a ruptured aneurysm include: Nausea and vomiting. Stiff neck.
Why does my neck hurt where my carotid artery is?
One of the common causes of pain in the neck is soreness and tenderness of one or both carotid arteries and is related to overdistention, relaxation, and increased pulsation in this vessel. The syndrome of vascular neck pain is closely related to the various forms of extracranial vascular headache.
Can a blocked artery in the neck cause dizziness?
Over time, stenosis can advance to complete blockage of the artery. Risk factors for carotid artery stenosis include age, smoking, high blood pressure, diabetes, obesity, and an inactive lifestyle. Some people with carotid artery stenosis may experience dizziness, fainting, and blurred vision.
Does a blocked carotid artery make you tired?
The extra effort that your body must make to move blood through narrowed or hardened arteries will be apt to leave you feeling fatigued or tired quite frequently.
Can you have good blood pressure and still have clogged arteries?
Although high blood pressure is common, it’s not harmless. High blood pressure is a major cause of atherosclerosis, the artery-clogging process that leads to heart attacks and strokes. Blood pressure higher than 130/80 is seen in: 69% of people who have their first heart attack.
