Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment Carotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid arteries. This 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.

Carotid Artery Stenosis The narrowing usually results from atherosclerosis, or a build-up of plaque on the inside of the arteries. Over time, stenosis can advance to complete blockage of the artery. Risk factors for carotid artery stenosis include age, smoking, high blood pressure, diabetes, obesity and an inactive lifestyle.ver time, stenosis can advance to complete blockage of the artery.

- If a TIA is caused by blockage in the main artery in the neck that supplies blood to the brain, called the carotid artery, surgeries may be required to open the artery, and prevent a stroke. These procedures are known as endarterectomy and stenting.

Symptoms of Carotid Stenosis Carotid artery stenosis or carotid artery disease pertains to a narrowing activity within the heart’s carotid arteries, usually as a result of atherosclerosis or the build-up of plaque. As the build-up of fatty materials increases, it eventually forms a plaque under the carotid arterial wall’s inner lining.

Overview Carotid artery. 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. 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.his process is called atherosclerosis.

Understand Carotid Artery Disease Carotid artery disease is one of the primary causes of a stroke. These blockages caused by carotid artery disease can restrict blood flow to brain tissue or promote a blood clot that cuts off blood flow entirely, causing an ischemic stroke,the most common type of stroke. Identifying and treating carotid artery disease is critical in reducing the risk of a first or recurrent stroke.

Heart disease guide Heart disease health centre. Carotid artery disease: Causes, symptoms, tests, and treatment. The most common type of carotid artery disease is atherosclerosis, or narrowing of the carotid arteries because of a build-up of fatty plaque. Having carotid artery disease increases a person's risk of experiencing a stroke.

- Other causes of narrowing (stenosis) includes : Mass pressing against the artery as is the cases with a neighboring tumor, fluid filled cyst or the pregnant uterus. In pregnancy, the narrowing is temporary and is relieved upon change of position.

- In general, as the atherosclerotic burden increases - leading to carotid artery diameter reduction - the risk of active carotid disease, or stroke, increases as well. The explanation as to why higher degrees of stenoses equate with a higher risk of stroke is basically two-fold.

Carotid Artery Dissection Carotid Artery Dissection Causes. Carotid dissection occurs due to a tear in the wall of the artery, which makes blood leak in between the layers and separate them. This results in breakdown of the layers which tears the walls. The carotid arteries can break down for various reasons, such as: This is a disease of genetic connective tissue.

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.

Heart and Stroke Encyclopedia Carotid artery disease, also called carotid artery stenosis, occurs when the carotid arteries, the main blood vessels that carry oxygenated blood to the brain, become narrowed.

Carotid Endarterectomy Blood clots can partly or fully block a carotid artery. A piece of plaque or a blood clot also can break away from the wall of the carotid artery. The plaque or clot can travel through the bloodstream and get stuck in one of the brain's smaller arteries. 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.

Carotid artery stenosis The carotid artery divides into the internal carotid artery and the external carotid artery. The internal carotid artery supplies the brain. Plaque often builds up at that division, and causes a narrowing (stenosis). Pieces of plaque can break off and block the small arteries above in the brain, which causes a stroke.
