Medication
Some people with carotid artery stenosis may experience dizziness, fainting, and blurred vision. These may be signs that the brain is not receiving enough blood. In many cases, the first symptom is a stroke or transient ischemic attack (TIA). A small blood clot can form in the artery narrowed by atherosclerosis.

What happens when plaque builds up in the carotid artery?
Plaque buildup can lead to narrowing or blockage in the carotid artery which, when significant, can put an individual at increased risk for stroke.
Why do we need to open the carotid artery?
If there is severe narrowing or blockage in the carotid artery, a procedure may be necessary to open the artery and increase blood flow to the brain, to prevent a future stroke.
What is the cause of carotid artery stenosis?
Carotid artery disease, also called carotid artery stenosis, is the narrowing of the carotid arteries, usually caused by atherosclerosis. Atherosclerosis is the buildup of cholestero l, fat and other substances traveling through the bloodstream, such as inflammatory cells, cellular waste products, proteins and calcium.
Where is the incision for carotid artery blockage?
During the procedure, an incision is made in the neck at the site of the carotid artery blockage. The surgeon removes the plaque from the artery and when the plaque removal is complete, the surgeon stitches the vessel closed. Blood flow to the brain is restored through its normal path.
Which arteries supply blood to the brain?
The carotid arteries supply blood to the large, front part of the brain, where thinking, speech, personality and sensory and motor functions reside. The vertebral arteries run through the spine and supply blood to the back part of the brain (the brainstem and cerebellum).
How to treat carotid artery disease?
The options include: 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.

What is a carotid stent?
Carotid stenting. In carotid stenting, a long, hollow tube (catheter) is threaded through the arteries to the narrowed carotid artery in the neck. A metal mesh tube (stent) is inserted into the vessel to serve as a scaffold that helps prevent the artery from narrowing again. The catheter and the filter — which catches any debris ...
How is carotid endarterectomy done?
Treatment. In carotid endarterectomy, your surgeon opens the carotid artery to remove atherosclerotic plaques. In carotid angioplasty, a long, hollow tube (catheter) is threaded through the arteries to the narrowed carotid artery in the neck. A filter is inserted to catch any debris that may break off during the procedure.
What is the procedure called when a catheter is inserted into the neck?
Carotid angioplasty. In carotid angioplasty, a long, hollow tube (catheter) is threaded through the arteries to the narrowed carotid artery in the neck. A filter is inserted to catch any debris that may break off during the procedure. Then, a tiny balloon at the end of the catheter is inflated to open the narrowed area.
What is the sound of a narrowed artery?
The exam generally includes listening for a swooshing sound (bruit) over the carotid artery in your neck, a sound that's characteristic of a narrowed artery.
What to do if you have a blockage in your arteries?
If blockage is severe, or if you've already had a TIA or stroke, your doctor may recommend removing the blockage from the artery.
How does a carotid artery stent work?
Carotid artery stenting (CAS) involves a thin catheter being threaded through the blood vessels, usually starting from the femoral artery in the thigh, up into the carotid artery . This is done under fluoroscopic guidance, so the specialist can see what they’re doing. Once the catheter is in position, a stent is placed into the artery to help open it up and keep it open. In general, recovery time from CAS is quicker than that of CEA.
What is the first step in treatment?
Treatment Considerations. The first step is to decide if any treatment beyond medicine is required at all. A major factor in decision-making is whether the stenosis has already caused a stroke or not. If not, and if the stenosis is less than about 80%, many doctors prefer just medical management.
What are the two blood vessels that run up the neck?
The carotid arteries are two blood vessels that run up along the sides of your neck into your brain. Together with the two vertebral arteries at the back of the neck, the carotids allow a way for the brain to receive the blood it needs for oxygen. Darrin Klimek / Digital Vision / Getty Images.
What happens when a plaque builds up in the heart?
When a plaque builds up in a vessel of the heart, it can cause a heart attack. When a plaque builds up in a blood vessel either in or traveling to the brain, it can cause a stroke . Carotid stenosis is a term used to indicate a narrowed carotid artery. When a plaque narrows the carotid artery, it can cause a stroke in two ways.
Why do doctors prescribe blood thinners?
In addition, the doctor will usually prescribe some form of blood thinner to prevent a clot from forming and blocking off the artery or traveling to the brain.
Is carotid stenting a stroke?
If a stroke has occurred, it may be an indication that more aggressive treatment is needed. If the stroke is too large, however, there may not be enough brain left to justify the risks of the procedure. Since its introduction in the late 1990s, carotid stenting has slowly been gaining popularity.
Can carotid stenosis be ignored?
Because carotid stenosis is such a risk factor for stroke, it cannot just be ignored. However, there’s some controversy about how carotid stenosis is best treated. There are three main ways to treat carotid stenosis:
Why do carotid arteries become narrow?
For many reasons, these major arteries may become narrow, decreasing the blood flow to the brain and increasing the risk of stroke. The most common reason why these arteries become narrow or blocked is atherosclerotic disease.
What is it called when you have plaque in your carotid arteries?
This condition is known as amaurosis fugax. Patients with plaque and narrowing in their carotid arteries will also frequently have plaque in the arteries to their heart and may be at increased risk for a heart attack.
What is the procedure called when the artery is cleaned out of the plaque?
This procedure is called carotid endarterectomy. During the surgery, the artery is cleaned out of the plaque. For women the statistics are slightly different. A woman usually must have a narrowing greater than 70% to benefit from carotid endarterectomy surgery.
Why do clots form in the arteries?
Clots can form in the artery because of the narrowing. The clot may then travel to the brain and completely block a blood vessel. The narrowing of the carotid artery is known as carotid stenosis. The plaque in the artery is common in people who smoke, have diabetes, a family history of this problem, uncontrolled high blood pressure ...
What happens when blood travels between the layers of the artery wall?
In other cases, the walls of the artery may split. (This is called a dissection. ) When this happens, blood can travel between the layers of the artery wall. This makes the inside of the artery narrower. It sometimes entirely blocks the artery. This may result in a stroke.
Where is a stent placed?
In these cases, a stent can be placed in the carotid artery. In this procedure, the patient has an angiogram. A small tube is placed in an artery in the groin. The tube is fed up through the artery to the point where the narrowing is. Then, a small alloy metal tube known as a stent is threaded through the first tube and placed in the narrow spot ...
Can fibromuscular dysplasia cause carotid stenosis?
It sometimes entirely blocks the artery. This may result in a stroke. Other more rare conditions that can cause carotid stenosis include fibromuscular dysplasia and Takayasu's arteritis. In these diseases, there may be many areas of one artery (or many arteries) involved with narrowing.
