Overview 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 fourth most common cause of death and the leading cause of permanent disability in the U.S. Carotid artery disease develops slowly. The first sign that you have the condition may be a stroke or transient ischemic attack (TIA). TIA is a temporary shortage of blood flow to your brain.

Carotid Artery Disease: Symptoms, Tests, Prevention, and Treatment This can lead to loss of brain function or even death. There are several ways that CAD can cause a stroke: 1  Narrowed carotid arteries may not supply enough blood to the brain.  A piece of plaque can break off and lodge in one of the smaller arteries of your brain, blocking blood flow.

Carotid Artery Blockage Symptoms Reducing your cholesterol levels, exercising, eating unrefined carbohydrates and a diet low in saturated fats, especially trans-fatty acids, are all ways to reduce the chances of your carotid arteries being clogged or blocked. If you are a smoker, quitting will make the biggest change in your risk factor and should seriously be considered. Symptoms of Carotid Artery Blockage. Carotid artery blockage will cause a stroke in its worst form. The simpler version that you will want to know the symptoms for is actually called a transient ischemic attack, or a TIA. According to the Mayo Clinic, the symptoms for a blockage of arteries are almost the same as for a stroke, but they are only temporary. You should seek emergency care immediately if you experience sudden numbness to one side of your face, arm or leg.

Carotid Endarterectomy This can block blood flow in the artery and cause a stroke. Carotid artery disease may not cause signs or symptoms until the carotid arteries are severely narrowed or blocked. For some people, a stroke is the first sign of the disease.therosclerosis can affect any artery in the body. For example, if plaque builds up in the coronary (heart) arteries, a heart attack can occur. If plaque builds up in the carotid arteries, a stroke can occur. A stroke also can occur if blood clots form in the carotid arteries.

Top 30 Doctor insights on: External Carotid Artery Stenosis Symptoms Carotid Artery Stenosis (Definition) Carotid artery stenosis is also known as Carotid artery disease. Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon.

What happens when the carotid artery is blocked? Because the carotid arteries deliver blood to the brain, carotid artery disease can have serious implications by reducing the flow of oxygen to the brain. The brain needs a constant supply of oxygen in order to function. Even a brief interruption in blood supply can cause problems.

Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment The carotid arteries are two large blood vessels that supply oxygenated blood to the large, front part of the brain. This is where thinking, speech, personality, and sensory and motor functions reside. You can feel your pulse in the carotid arteries on each side of your neck, right below the angle of the jaw line.his narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery. When the carotid arteries are obstructed, you are at an increased risk for a stroke, the third leading cause of death in the U.S.

Carotid Artery Disease: Symptoms, Tests, Prevention, and Treatment The carotid arteries deliver blood to the brain. One artery is located on each side of the neck. When your doctor puts his or her hands on your neck to detect a pulse, he or she is feeling for one of your carotid artery. Carotid artery disease (CAD) occurs when a blockage in one of these arteries decreases the blood flow to the brain. This can lead to stroke. According to an article in the journal Circulation, an average of 750,000 people have a stroke every year in the United States.

Carotid Artery Disease (Stroke Prevention) Like the arteries that supply blood to the heart -- the coronary arteries -- the carotid arteries can also develop atherosclerosis or “hardening of the arteries” on the inside of the vessels. Over time, the buildup of fatty substances and cholesterol narrows the carotid arteries.trokes can occur as a result of other conditions besides carotid artery disease. For example, sudden bleeding in the brain, called intracerebral hemorrhage, can cause a stroke. Other possible causes include: 1  Sudden bleeding in the spinal fluid space -- subarachnoid hemorrhage. 2  Atrial fibrillation.
