The carotid arteries lie on each side of the neck, extending from the aorta in the chest to the base of the skull. They perform a critical function as they are the main blood vessels to the brain. Sometimes due to the build-up of cholesterol and fat, plaque is formed, thereby narrowing the carotid arteries and reducing blood flow. This condition is known as carotid stenosis and it can lead to a stroke.
Treatment: Carotid stenosis is treated by a fairly common surgical procedure called a “carotid endartectomy” which can effectively prevent a stroke.
