Carotid artery disease

Medication[ edit ] Clinical guidelines such as those of National Institute for Clinical Excellence NICE [8] recommend that all patients with carotid stenosis be given medication, usually blood pressure lowering medications, anti-clotting medications, anti-platelet medications such as aspirin or clopidogreland especially statins which were originally prescribed for their cholesterol-lowering effects but were also found to reduce inflammation and stabilize plaque. Carotid endarterectomy reduces the risk of stroke or death from carotid emboli by about half.

Carotid artery disease

Carotid artery Carotid artery The carotid arteries are a pair of blood vessels located on both sides of your neck that deliver blood to your brain and head. 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. Stroke deprives your brain of oxygen. Within minutes, brain cells begin to die. Stroke is the most common cause of death and the leading cause of permanent disability in the U.

Carotid artery disease develops slowly.


The first sign that you have the condition may be a stroke or transient ischemic attack TIA. A TIA is a temporary shortage of blood flow to Carotid artery disease brain. Treatment of carotid artery disease usually involves a combination of lifestyle changes, medication and sometimes surgery.

Symptoms In its early stages, carotid artery disease often doesn't produce any signs or symptoms. 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 Sudden trouble seeing in one or both eyes Sudden dizziness or loss of balance Sudden, severe headache with no known cause When to see a doctor Seek emergency care if you experience any signs or symptoms of stroke.

Even if they last only a short while and then you feel normal, see a doctor right away. You may have experienced a TIA, an important sign that you're at risk of a full-blown stroke.

Talk to your doctor if you have risk factors for carotid artery disease. Even if you don't have any signs or symptoms, your doctor may recommend aggressive management of your risk factors to protect you from stroke.

Seeing a doctor early increases your chances that carotid artery disease will be found and treated before a disabling stroke occurs. Request an Appointment at Mayo Clinic Causes Carotid artery disease is caused by a buildup of plaques in arteries that deliver blood to your brain.

Plaques are clumps of cholesterol, calcium, fibrous tissue and other cellular debris that gather at microscopic injury sites within the artery.

Carotid artery stenosis - Wikipedia

This process is called atherosclerosis. Carotid arteries that are clogged with plaques are stiff and narrow. Clogged carotid arteries have trouble delivering oxygen and nutrients to vital brain structures that are responsible for your day-to-day functioning. Risk factors Factors that increase your risk of carotid artery disease include: Excess pressure on artery walls can weaken them and make them more vulnerable to damage.

Nicotine can irritate the inner lining of your arteries. Smoking also increases your heart rate and blood pressure. Diabetes lowers your ability to process fats efficiently, placing you at greater risk of high blood pressure and atherosclerosis.

High levels of low-density lipoprotein cholesterol and high levels of triglycerides, a blood fat, encourage the accumulation of plaques. Your risk of carotid artery disease is higher if a relative has atherosclerosis or coronary artery disease.

Arteries become less flexible and more prone to injury with age. Excess weight increases your chances of high blood pressure, atherosclerosis and diabetes.

Spells of stopping breathing at night may increase your risk of stroke. It contributes to conditions that damage your arteries, including high blood pressure, diabetes and obesity. Complications Ischemic stroke Ischemic stroke Ischemic stroke occurs when a blood clot blocks or plugs an artery leading to the brain.

A blood clot often forms in arteries damaged by the buildup of plaques atherosclerosis. It can occur in the carotid artery of the neck as well as other arteries. Carotid artery disease causes about 10 to 20 percent of strokes. A stroke is a medical emergency that can leave you with permanent brain damage and muscle weakness.Carotid artery disease occurs because of damage to the inner lining of the artery.

This is a gradual process that is associated with smoking, high blood pressure, high cholesterol levels, and poorly controlled diabetes.

Carotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid narrowing is usually caused by the buildup of fatty substances and.

Carotid artery disease is serious because it can cause a stroke, also called a "brain attack." A stroke occurs if blood flow to your brain is cut off.

If blood flow is cut off for more than a few minutes, the cells in your brain start to die. Treatment for carotid artery disease is given to reduce the possibility of stroke or recurrence of stroke.

Specifics depend on the degree of artery narrowing. MEDICATION, often a combination of medications, can help slow the progression of carotid artery disease. Carotid artery disease is serious because it can block the blood flow to your brain, causing a stroke. Too much plaque in the artery can cause a blockage.

Too much plaque in the artery can cause a blockage. Carotid artery disease, also called carotid artery stenosis, is the narrowing of the carotid arteries, usually caused by atherosclerosis.

Carotid artery disease

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.
