Your doctor may use carotid ultrasound, CT angiography (CTA), magnetic resonance angiography (MRA), or cerebral angiography to determine the presence and location of stenosis. Treatment to improve or restore blood flow may include angioplasty and vascular stenting or, in severe cases, surgery.
Although usually heard with the stethoscope, such sounds may occasionally also be palpated as a thrill. These sounds may be normal, innocent findings (i.e., a venous hum in a child) or may point to underlying pathology (i.e., a carotid artery bruit caused by atherosclerotic stenosis in an adult).
Although the bruit is usually heard with a stethoscope, it also can be felt on the overlying skin as a vibration, also referred to as a thrill. If you do not feel the thrill or hear the bruit in your access, call your doctor or the dialysis center immediately.
Definition. A bruit is an audible vascular sound associated with turbulent blood flow. Although usually heard with the stethoscope, such sounds may occasionally also be palpated as a thrill.
Carotid bruit in a gentleman with a 70% stenosis of his left carotid artery. A carotid bruit is a vascular murmur sound (bruit) heard over the carotid artery area on auscultation during systole.
Neck. By listening to the sides of the neck with a stethoscope, your doctor can screen for carotid narrowing by detecting a carotid bruit, an abnormal swooshing sound in the carotid artery.
A. "Mild" narrowing ranges from 15% to 49% blockage of the artery. Over time, this narrowing can progress and lead to a stroke. The presence of atherosclerotic plaque in the carotid artery is a predictor for future risk of cardiovascular disease.
The condition may go unnoticed until it's serious enough to deprive your brain of blood, causing a stroke or TIA. Signs and symptoms of a stroke or TIA include: Sudden numbness or weakness in the face or limbs, often on only one side of the body. Sudden trouble speaking and understanding.
Eat These 10 Foods to Cleanse Your Arteries
- Asparagus. Asparagus is one of the best foods to cleanse your arteries.
- Avocado. Avocado helps reduce the “bad” cholesterol and increase the “good cholesterol” that helps to clear the arteries.
- Broccoli.
- Fatty Fish.
- Nuts.
- Olive Oil.
- Watermelon.
- Turmeric.
Carotid artery stenosis: Narrowing of the carotid artery, usually due to cholesterol plaque buildup, or atherosclerosis. Carotid artery stenosis does not usually cause symptoms until it becomes severe. Fever, a severe headache on one side of the head, and jaw pain when chewing can be symptoms.

Blood clots can cause swelling in the veins of your neck or arms, but this is rare. Thrombphlebitis affects superficial veins and is a different condition than a deep vein thrombosis (DVT). Symptoms of thrombophlebitis include swelling, redness, and tenderness over the affected vein.
Feel for the pulse point low on your neck and don't press too hard. You can interrupt blood supply to the brain by applying pressure too high on the carotid artery. Pressing too hard may cause an irregular heartbeat.
Eat a heart-healthy diet
- Add more good fats to your diet. Good fats are also called unsaturated fats.
- Cut sources of saturated fat, such as fatty meat and dairy. Choose lean cuts of meat, and try eating more plant-based meals.
- Eliminate artificial sources of trans fats.
- Increase your fiber intake.
- Cut back on sugar.
Thankfully, there are natural solutions including the one we're about to show you. By using lemon juice, apple cider vinegar and honey, you will be able to simply and healthfully unclog arteries and control blood pressure.
Narrowing, or stenosis, of the carotid is considered mild when it reduces the width of the artery by less than 50%; narrowing of 50% to 69% is considered moderate, while 70% to 99% is considered severe carotid stenosis.
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.
You may need the test if: You have already had a stroke or mini-stroke (transient ischemic attack, or TIA). You have sudden symptoms of stroke or mini-stroke, including: Weakness or numbness on one side of the face or body.
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. 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.
Surgery is best for most patients with symptoms: Carotid endarterectomy should be strongly considered for symptomatic patients with 70 to 99 percent blockage in the carotid artery. It also should be considered for those with 50 to 69 percent stenosis.
At Penn Medicine, our neurologists and neurosurgeons work with a multidisciplinary team that includes vascular surgeons and interventionists to provide care to patients with carotid artery disease.
Carotid ultrasound (also called sonography) is the most common test for diagnosing carotid artery disease. It's a painless, harmless test that uses sound waves to create pictures of the insides of your carotid arteries. This test can show whether plaque has narrowed your carotid arteries and how narrow they are.
How Accurate Is Carotid Ultrasound? Using peak systolic velocity to determine degree of stenosis, Doppler ultrasound correctly classified 91 percent of stenoses less than 50 percent, 33 percent of stenoses between 50 percent and 69 percent, and 87 percent of stenoses 70 percent or greater.
You can feel your carotid artery simply by placing a finger on your neck. Your doctor can hear that noise, called a bruit, simply by listening to your carotid arteries through his stethoscope. Unfortunately, when it comes to detecting carotid stenosis, the ear isn't much better than the finger.
Carotid plaque prevalence and severity rose steeply from age 40 (figure 1A). The prevalence of minimal plaque increased from 4.5% in the age group 25–29 to 51.2% in the age group 65–69, and the prevalence of moderate plaque rose from 0.8% in the age group 30–34 to 25.0% in the age group 65–69 years.
Are there tests for clogged arteries?
- Cholesterol screening.
- Chest X-ray.
- CT scan.
- Ultrasound.
- Echocardiogram and/or cardiac stress test.
- Electrocardiogram.
- MRI or PET scanning.
- Angiogram.
Carotid Artery MRI
More recently, researchers have been evaluating the use of MRI in identifying arterial plaques that are more "vulnerable" - that is, more likely to cause strokes. In one recent study, researchers concluded carotid MRI can "accurately predict" strokes even in those with no history of heart disease.
