What does a carotid ultrasound reveal?

What does a carotid ultrasound reveal?

Carotid ultrasound is done to detect plaque buildup in one or both of the carotid arteries in the neck and to see whether the buildup is narrowing your carotid arteries and blocking blood flow to the brain. Test results will help your doctor plan treatment to remove the plaque and help prevent a stroke.

What are the symptoms of a blockage in the carotid artery?


  • Sudden numbness or weakness in the face or limbs, often on only one side of the body.
  • Sudden trouble speaking and understanding.
  • Sudden trouble seeing in one or both eyes.
  • Sudden dizziness or loss of balance.
  • Sudden, severe headache with no known cause.

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.

Can ultrasound detect blocked 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.

Why would a doctor order a neck ultrasound?

Your doctor would order an ultrasound of the neck if he or she suspects a problem or a developing condition in your carotid arteries, lymph nodes or thyroid.

How long can you live with 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.

Why would a doctor ask for a thyroid ultrasound?

Thyroid ultrasound is used to identify and characterize thyroid nodules, and is not part of the routine evaluation of abnormal thyroid function tests (over- or underactive thyroid function) unless the patient also has a palpably large goitre or a nodular thyroid.

What to expect during a carotid ultrasound?

A standard carotid ultrasound shows the structure of a carotid artery. It may include a Doppler ultrasound – a special ultrasound that shows the movement of blood through the blood vessels. A doctor often will need results from both types of ultrasound to fully assess if there is a problem with blood flow through the carotid arteries.

How much does a carotid artery ultrasound cost, please?

For about $150, you can undergo a series of ultrasound scans, which the companies claim can uncover potentially dangerous cardiovascular conditions. One scan looks at your carotid arteries, which run up either side of your neck.

What does these carotid artery ultrasound indicate?

A carotid ultrasound is an important test that can detect narrowing, or stenosis of the carotid arteries. Carotid artery stenosis is a major risk factor for stroke. You have two carotid arteries, one on each side of your neck. Carotid arteries are major arteries that carry blood from your heart to your brain. A buildup of plaque can narrow or block your carotid arteries. This is called carotid artery disease, which increases your risk of stroke.

What percent of carotid artery blockage requires surgery?

Asymptomatic and symptomatic carotid artery disease with blockage of 50 percent to 69 percent (with results from diagnostic tests indicating blockage closer to 69 percent) may require surgical treatment.
