What does carotid bruit indicate?
A carotid bruit is a vascular sound usually heard with a stethoscope over the carotid artery because of turbulent, non-laminar blood flow through a stenotic area. A carotid bruit may point to an underlying arterial occlusive pathology that can lead to stroke.
Treatments. Mild to moderate blockages in the carotid artery are treated with medications called antiplatelet agents, such as aspirin, that block the formation of blood clots. In addition, treatment involves identifying and reducing risk factors, such as cigarette smoking and high blood pressure.
If an ultrasound test shows no obstruction or narrowing of the arteries, a carotid artery bruit may be called innocent, since it doesn't increase the risk for stroke. Innocent carotid bruits are more common in children and young people who have a faster heart rate and greater flow of blood through the carotid arteries.
Bruits are blowing vascular sounds resembling heart murmurs that are perceived over partially occluded blood vessels. When detected over the carotid arteries, a bruit may indicate an increased risk of stroke; when produced by the abdomen, it may indicate partial obstruction of the aorta or…
The midcarotid bruit is usually localized and either disappears or diminishes in intensity as one moves the stethoscope down the neck. The bruit tends to become more apparent when stenosis is 50% or greater but may actually disappear when stenosis reaches 85% to 90%.
Carotid bruits are detected in 4% to 5% of the population aged 48 to 80 years and are associated with internal carotid artery stenosis in 50% of cases. Other causes of carotid bruits include increased venous flow, external carotid artery stenosis, and transmitted cardiac murmur.
What causes a bruit in the carotid artery? Atherosclerosis is the most common cause of a carotid bruit. Atherosclerosis is a medical term that refers to the buildup of plaque (a fatty substance) in arteries throughout your body. This plaque narrows the lumen (opening) of your arteries, limiting blood flow.
Surgery isn't recommended in cases where there's minor stenosis (less than 50%). This is because surgery is most beneficial for people with moderate and severe stenosis (more than 50%). The maximum benefit is seen in those with severe stenosis (70 to 99%).
Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.
Patients without hypertension should not have auscultation for asymptomatic renal artery bruits because bruits frequently are a normal finding.
Can a bruit be normal?
The carotid bruit can be a normal finding in a healthy person with no disease, or it can be an indication of severe carotid artery stenosis, a harbinger of impending stroke.
A bruit is the sound of blood flowing through a narrowed portion of an artery. The sound means that the blood flow may be partially blocked; artery blockage is most often due to atherosclerosis (hardening of the arteries).

BRUITS IN HEALTHY PERSONS. Bruits occur in 4% to 20% of healthy persons. Abdominal bruits are more common in those younger than 40 years than in older persons. Characteristically, the abdominal bruit of a healthy individual is systolic, medium- to low-pitched, and audible between the xiphoid process and umbilicus.
Key Words: atherosclerosis
1,2 In a recent meta-analysis, we found that the presence of a carotid bruit significantly increased the risk of myocardial infarction and cardiovascular death.
Localized supraclavicular bruits are caused either by subclavian or vertebral origin artery stenosis. Diffuse bruits are transmitted from the arch of the aorta or the heart. bruit will be of short duration and heard just in mid-systole.
There are two carotid arteries, one on each side of your neck. Dissection can occur spontaneously or after a neck injury. The condition can heal itself over time but may cause life-threatening complications, such as stroke or bleeding in the brain.
- Sudden loss of vision, blurred vision, or difficulty in seeing out of one or both eyes.
- Weakness, tingling, or numbness on one side of the face, one side of the body, or in one arm or leg.
- Sudden difficulty in walking, loss of balance, lack of coordination.
Medications. Medications that may be used to treat carotid artery disease include: Antiplatelet medications - medications used to decrease the ability of platelets in the blood to stick together and cause clots. Aspirin, clopidogrel, ticlopidine, and dipyridamole are examples of antiplatelet medications.
Routine auscultation of the carotids has a compelling rationale. In the asymptomatic patient, a bruit may indicate occult carotid artery stenosis that can be repaired surgically before it causes stroke, thus preventing the unsuspecting patient from death or crippling stroke.
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.
What do they do if your carotid artery is blocked?
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.
How long is the life expectancy with blocked carotid artery with symptoms? Many times people live happily with a blocked artery. But with one blocked artery symptoms are a high chance of reduced life expectancy. Asymptomatic patients live up to 3-5 years.
First cause of secondary hypertension is renovascular hypertension which presents abdominal bruit in 16 to 20% of cases.
Your neck may feel tender in the area of the artery. The pain often goes up the neck to the jaw, ear, or forehead. Some diseases can cause carotidynia. Your doctor will check for those.
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.
Many people function normally with one completely blocked carotid artery, provided they haven't had a disabling stroke. If narrowing hasn't caused complete blockage, then a revascularization procedure may be warranted.
Ju says that it's important to use a team approach involving primary care physicians, cardiologists and neurologists to collaborate and offer the best options to treat patients with carotid stenosis and help prevent stroke.
A carotid endarterectomy usually takes 1 to 2 hours to perform. If both of your carotid arteries need to be unblocked, 2 separate procedures will be carried out. One side will be done first and the second side will be done a few weeks later.
A CT scan can give your physician extensive information about where you may have narrowing in the carotid arteries. For the test, you may also be administered contrast dye, a substance that makes it easier to see the blood vessels.
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.
What is abnormal bruit?
Bruit, also called vascular murmur, is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
A carotid bruit is an abnormal vascular sound usually heard with a stethoscope over the carotid artery. A bruit describes the sound of blood flowing through a narrowed portion of an artery. It makes a “swooshing” sound, and it can be indicative of a clogged artery.

Surgery is usually advised for carotid narrowing of more than 70%. Surgical treatment decreases the risk for stroke after symptoms such as TIA or minor stroke.
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.
Carotid bruit is clearly an indicator of increased stroke risk but chiefly as a general and nonfocal sign of advanced atherosclerotic disease and not necessarily as an indicator of local arterial stenosis preceding cerebral infarction.
