What are the health implications of a build up of plaque in the carotid arteries in the neck?

the arteries become narrowed and the flow of blood and oxygen is blocked. Blockages can cause pain in the chest (angina) and eventually, when the blood vessels are occluded (closed up), a heart attack.

Definition of carotid artery stenosis?
The cause of carotid stenosis is the buildup of plaque on the inner wall of the carotid artery. The reduced blood flow to the brain and the blockage of other arteries following the release of emboli can cause a stroke.
Can a blockage in the carotid artery cause dizziness when wearing tight collars?
I would think that if BOTH carotid arteries have (at least) 70% stenosis (narrowing) due to hardening of the arteries (a build-up of plaque and fat), you could cause dizziness... If you have this problem you need to see a vascular surgeon immediately for evaluation and treatment!
What clogs arteries forming heart attacks?
Plaque clogs arteries. Plaque comes from a diet of fatty foods.
How do you test for carotid artery blockage?
To check your carotid arteries, your doctor will listen to them with a stethoscope. He or she will listen for a whooshing sound called a bruit. This sound may indicate changed or reduced blood flow due to plaque buildup. To find out more, your doctor may recommend tests.Diagnostic TestsThe following tests are common for diagnosing carotid artery disease. If you have symptoms of a mini-stroke or stroke, your doctor may use other tests as well. Carotid UltrasoundCarotid 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. A standard carotid ultrasound shows the structure of your carotid arteries. A Doppler carotid ultrasound shows how blood moves through your carotid arteries.Carotid AngiographyCarotid angiography (an-jee-OG-ra-fee) is a special type of x ray. This test may be used if the ultrasound results are unclear or don't give your doctor enough information. For this test, your doctor will inject a substance (called contrast dye) into a vein, most often in your leg. The dye travels to your carotid arteries and highlights them on x-ray pictures.Magnetic Resonance AngiographyMagnetic resonance angiography (MRA) uses a large magnet and radio waves to take pictures of your carotid arteries. Your doctor can see these pictures on a computer screen. For this test, your doctor may give you contrast dye to highlight your carotid arteries on the pictures.Computed Tomography AngiographyComputed tomography (to-MOG-rah-fee) angiography, or CT angiography, takes x-raypictures of the body from many angles. A computer combines the pictures into two- and three-dimensional images. For this test, your doctor may give you contrast dye to highlight your carotid arteries on the pictures.
What is the surgical removal of the lining of a portion of a clogged carotid artery leading to the brain is known?
Carotid endarterectomy is the process to remove the plaque on the lining of a clogged carotid artery.
What can be heard in the neck when the carotid arteries fill with plaque?
An examiner may hear a carotid bruit in the neck if the carotids are blocked with plaque.
What is a carotid endartectomy performed?
The medical procedure carotid endarterectomy entails the removal of plaque buildup from the carotid arteries. This is done through a small incision at the top of the neck.
Definition of carotid artery stenosis?
The cause of carotid stenosis is the buildup of plaque on the inner wall of the carotid artery. The reduced blood flow to the brain and the blockage of other arteries following the release of emboli can cause a stroke.
What does the medical abbreviation cva hx of carotid stenosis mean?
It will read "CVA- Hx of carotid stenosis" The doctor is describing a stroke, with a prior history of a narrowing in some of the main vessels (carotid arteries) running in the neck, which can be due to cholesterol plaque buildups that predispose to strokes.

What is the prognosis for carotid stenosis?
Carotid endarterectomy is the surgical exposure of the carotid artery and the removal of the plaque. This re-establishes the uninterrupted flow of blood to the brain.
What clogs arteries forming heart attacks?
Plaque clogs arteries. Plaque comes from a diet of fatty foods.
Where is the most common location for plaque development?
Plaque in your arteries is very bad - it can contribute to clots, which in turn can cause heart attacks, loss of blood flow to muscles, or other health conditions. There is not one place in the body where this type of plaque is most common. Any plaque in the arteries, no matter where it is, can cause problems. Plaque closer to the heart can cause more fatal problems than, say, plaque in the legs.
How can plaque harm your heart?
can cause a stroke if it completely blocks the brain (carotid) arteries. Atherosclerosis can also occur in the arteries of the neck, kidneys, thighs, and arms, causing kidney failure or gangrene and amputation.

Why is a carotid endartectomy performed?
A carotid endarterectomy is performed on those who have suffered a mild stroke because of a carotid artery disease. Depending on the circumstances as well as how extreme the disease is increases the risks of a carotid endarterectomy.
