What is Carotid Artery Stenosis

Carotid blockage, also known as carotid artery stenosis, is a condition that occurs when the carotid arteries, which are the major arteries in the neck that supply blood to the brain, become narrowed or blocked. Carotid blockage can be caused by a build-up of plaque, which is a mixture of cholesterol, fat, and other substances, in the walls of the arteries.

Carotid blockage can increase the risk of stroke, as it can reduce the blood flow to the brain and lead to the formation of blood clots.

Symptoms of carotid blockage may include weakness or numbness on one side of the body, difficulty speaking or understanding speech, difficulty seeing in one or both eyes, and dizziness. However, many people with carotid blockage do not experience any symptoms.

Carotid blockage is typically diagnosed with a test called a carotid ultrasound, which uses sound waves to create images of the carotid arteries. Other tests that may be used to diagnose carotid blockage include a CT scan, an MRI, and an angiogram.

Treatment for carotid blockage may include medications to lower cholesterol and blood pressure, as well as lifestyle changes, such as quitting smoking and following a healthy diet. In some cases, surgery may be necessary to remove plaque from the carotid arteries or to bypass the blocked portion of the artery. It is important to seek medical attention if you are experiencing symptoms that may be caused by carotid blockage.
