Medication
Treatment options should be carefully considered for blocked carotid arteries. Symptoms of carotid artery stenosis include transient blindness in one eye, weakness or numbness of an arm, leg or the face, or the temporary inability to speak or to understand conversation. Angioplasty and stenting is an option for higher risk symptomatic patients:...
Procedures
Treatment can include: Medication (antiplatelet drug therapy) and risk factor management. Risks factors include high blood pressure, obesity, high cholesterol, diabetes, and tobacco use. Carotid endarterectomy, a surgery where the carotid artery is opened and the fatty deposits are removed.
Self-care
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.
Nutrition
And the treatment has been shown to have a lower stroke risk than traditional stenting or surgery. Although it’s not the best option for everyone, TCAR can be an attractive treatment alternative for many people who have severe carotid stenosis and are at high risk for stroke.

Do cardiologists treat carotid artery disease?
In conclusion, cardiologists perform the majority of carotid stenting in the United States. Procedures performed by cardiologists involve patients who appear to differ in important ways from those treated by other specialists like surgeons and radiologists.
Can a person live with one blocked carotid artery?
A network of blood vessels at the base of the brain, called the circle of Willis, can often supply the necessary blood flow. Many people function normally with one completely blocked carotid artery, provided they haven't had a disabling stroke.
How to treat carotid stenosis?
Treatment for severe carotid stenosis involves eliminating the artery blockage. The most common way to do that is with a surgery called “ carotid endarterectomy .”. It’s performed by making an incision along the front of the neck, opening the carotid artery and removing the plaque.
What is a TCAR procedure?
There is a new treatment, however, called transcarotid arterial revascularization, or TCAR, that uses a different approach to opening a blocked carotid artery. The risk of a stroke during that procedure may be lower than it would be with other methods.
What is a TCAR stent?
With TCAR, a stent can be placed to open the artery and relieve the blockage, while the brain is protected from any debris that could lead to a stroke.
What is the coil called that is inserted to keep the artery open?
The balloon is inflated to widen the artery, pushing the plaque to the side, and a small wire mesh coil, called a stent, is inserted to keep the artery open. During both procedures, there is a risk that a stroke could occur if, as the surgeon is working, plaque is dislodged and travels to the brain. During angioplasty, there’s also ...
Can a stroke cause a carotid stenosis?
ANSWER: Carotid stenosis is a common cause of stroke, so it’s crucial that your husband be treated for his condition. Traditional treatments for carotid stenosis can pose a small risk of triggering a stroke. There is a new treatment, however, called transcarotid arterial revascularization, or TCAR, that uses a different approach to opening ...
Is carotid stenosis dangerous?
Carotid stenosis is particularly dangerous because as plaque builds up inside a carotid artery, the plaque becomes increasingly unstable, and the plaque blockage bursts, releasing pieces of plaque into the bloodstream. Those pieces are carried up into the brain, where they can become lodged in a blood vessel and lead to a stroke.
Can a tcar catheter cause a stroke?
During angioplasty, there’s also a risk that blood clots may form on the catheter or plaque may break loose and travel to the brain, possibly leading to a stroke. The new TCAR technique is a hybrid of the two techniques. It involves making a tiny incision at the base of the neck and, from there, inserting a stent into the carotid artery.
What is the procedure to open the carotid artery?
Carotid endarterectomy, a surgery where the carotid artery is opened and the fatty deposits are removed. Carotid angioplasty and stenting, where a long, hollow plastic tube (catheter) is inserted in the groin artery and threaded to the narrowed carotid artery.
How much is a partial blockage risk?
A partial blockage (greater than 60 percent) in patients without symptoms carries a risk of stroke of about 2 percent each year. That increased risk needs to be weighed against the risk and benefits of treatment.

Carotid artery disease can be treated medically, interventionally or surgically. Once the doctor confirms that you have carotid artery disease, the treatment will depend on the degree of narrowing and if you are having symptoms.
What is the procedure for a carotid artery shunt?
Carotid Endarterectomy (CEA) Carotid endarterectomy is the most commonly performed surgical treatment for carotid artery disease. During carotid endarterectomy, the surgeon reduces the risk of stroke from the operation by shunting (using a plastic tube to re-route blood flow to the brain) and monitoring the patient carefully.
What is carotid stenting?
For patients who meet certain eligibility criteria, carotid stenting offers an alternative approach to repairing the blockage in the artery. Carotid stenting is approved as a carotid artery disease surgical treatment for patients who are experiencing symptoms, have a carotid artery that is blocked 70 percent or more, and for whom surgery would be high risk. Some examples of patients who might benefit from this approach as opposed to carotid endarterectomy include patients who have had prior surgery or radiation surgery in the neck.
What is the medication used for angioplasty?
A medication such as heparin may be given during the procedure to reduce the risk of blood clots. During the angioplasty procedure, a carotid stent (a small, metal mesh tube) is placed inside the carotid artery at the site of the blockage and provides support to keep the artery open.
What is the procedure for angioplasty?
When the balloon is inflated, the fatty plaque or blockage is compressed against the artery walls to improve blood flow. A medication such as heparin may be given during the procedure to reduce the risk of blood clots.
What is the procedure called when the artery is cleaned out of the plaque?

Symptoms of Clogged Arteries
Clogged arteries are caused by atherosclerosis, which develops over time as plaques formed from fats, minerals, cholesterol, and more build up inside the walls of your arteries. These buildups cause the inner tunnels, called lumens, of the arteries to become smaller and narrower.
What Causes Clogged Arteries?
Clogged arteries are caused by a buildup of plaque in your arteries. Plaque is usually made up of a few substances, including minerals like calcium, or fats and cholesterol. High cholesterol levels can lead to this buildup of plaques.
Risk Factors for Clogged Arteries
A diet that is high in fats and cholesterol is just one of the things that can contribute to a buildup of plaques and clogged arteries.
Diagnosis
Diagnosing arterial problems may begin with your primary care doctor, but if a blockage is suspected, you will most likely be referred to a cardiologist or vascular specialist.
Treating Clogged Arteries
Treating clogged arteries should be done with a holistic approach. Your doctor will first address the problems that led to the clogged artery. Lifestyle changes are key, and may include:
Complications
The most concerning complications of clogged arteries are heart attack and stroke. A heart attack can occur when there is blockage in the coronary arteries, which supply blood to the heart. When a blockage affects the brain, this is called an ischemic stroke. This type of stroke can be treated effectively with strong blood thinners.
Prevention and Management
The key to keeping your arteries clear of blockages is to eat a low-fat diet and exercise regularly. Plant-based diets have even been shown to help reverse coronary artery disease in some people. 8
What can I do to remove a blockage in my arteries?
In serious cases, medical procedures or surgery can help to remove blockages from within the arteries. A doctor may also prescribe medication, such as aspirin, or cholesterol-reducing drugs, such as statins.
What to do if your arteries are clogged?
A doctor may recommend medications to lower LDL cholesterol to use alongside dietary changes.
What are the complications of clogged arteries?
Clogged arteries, if they are left unchecked, can lead to conditions such as: Heart disease, which is where plaque builds up in the arteries in and around the heart. Angina, a condition where chest pain results from a lack of blood flow to the heart. Peripheral artery disease, which is where plaque builds up in the arms and legs.
What is plaque in arteries?
What are clogged arteries? Plaque is a mixture of fat, calcium, cholesterol, and waste from the cells in the body. This mix can stick to the walls of the arteries, making these blood vessels narrower. When this happens, it is called atherosclerosis.
How to reduce plaque buildup in the heart?
Exercising regularly. Obesity is a risk factor for plaque buildup and heart disease. In addition to eating a healthful diet, regularly exercising may help a person to lose weight and reduce their risk of heart problems.
Can blocked arteries cause heart attacks?
Clogged or blocked arteries can stop fresh blood from reaching parts of the body, which can put a person at risk of a heart attack, heart failure , or stroke. In many cases, people can prevent a plaque buildup and atherosclerosis. Some medical treatments are available to help clear the arteries, but they are invasive.
How to stop a PAD from getting worse?
Taking medicine and walking more can actually reduce your symptoms and help keep PAD from getting worse. Some doctors mistakenly recommend having surgery or angioplasty even if you do not have symptoms. However, this does not make people with PAD feel better or prevent future leg problems.
What to do if your leg hurts when walking?
If PAD causes severe leg pain when walking, you may stop doing that and other activities . Surgery to bypass the blockage can relieve these symptoms. So can another procedure known as angioplasty.
How long does it take for a leg bypass to heal?
Bypass surgery on your legs has all the dangers of major surgery. It takes two to three weeks for the wound to heal. Risks include infection, bleeding from the wound, and complications from anesthesia, such as trouble breathing or pneumonia. And about three out of 100 people who have bypass surgery have a heart attack or die.
What does it mean when your legs are blocked?
When this happens, less blood flows to your legs. This is called peripheral artery disease (PAD). If your leg arteries are badly blocked, you may develop foot pain while resting or a sore that won’t heal.
Can a stent come apart?
Rarely, when a stent is being inserted, dangerous bleeding may happen and the stent may come apart. Both procedures can, in rare cases, cause a partly blocked artery to close up completely. Then you may need an emergency procedure. If the procedure cannot be done right away, your leg may have to be amputated.
Can you walk every day after angioplasty?
Studies show that walking every day can relieve symptoms just as well as angioplasty, in some cases.
Do people with PAD need surgery?
Most people with PAD never develop problems that need surgery or angioplasty. This is because they do not have symptoms or because medicine and exercise work well enough to treat the pain and allow a normal lifestyle.

Causes
- Carotid stenosis occurs when fatty deposits, or plaques, block the carotid arteries the blood vessels that deliver blood to your brain and head. The blockage increases stroke risk. A stroke is a medical emergency that occurs when the blood supply to the brain is interrupted or significantly reduced. Stroke is the leading cause of permanent disability in the U.S.
Definition
- Carotid stenosis is particularly dangerous because as plaque builds up inside a carotid artery, the plaque becomes increasingly unstable, and the plaque blockage bursts, releasing pieces of plaque into the bloodstream. Those pieces are carried up into the brain, where they can become lodged in a blood vessel and lead to a stroke.
Research
- During both procedures, there is a risk that a stroke could occur if, as the surgeon is working, plaque is dislodged and travels to the brain. During angioplasty, theres also a risk that blood clots may form on the catheter or plaque may break loose and travel to the brain, possibly leading to a stroke.
Symptoms
- The new TCAR technique is a hybrid of the two techniques. It involves making a tiny incision at the base of the neck and, from there, inserting a stent into the carotid artery. While the stent is being placed, blood flow through the carotid artery is reversed temporarily. This is accomplished by inserting a small device into the carotid artery that removes the blood and reroutes it to a vein in …
Medical uses
- That external circuit contains a pump to move the blood and a filter to remove any plaque that may break free from the artery during the procedure. With TCAR, a stent can be placed to open the artery and relieve the blockage, while the brain is protected from any debris that could lead to a stroke.
Diagnosis
- Research has shown that the temporary reversal of blood flow during TCAR is safe. And the treatment has been shown to have a lower stroke risk than traditional stenting or surgery. Although its not the best option for everyone, TCAR can be an attractive treatment alternative for many people who have severe carotid stenosis and are at high risk for stroke. Dr. Andrew Olden…
