Carotid Artery Stenosis
Pronounced: kah-rah-tid ar-tur-ree steh-noh-sisEn Español (Spanish Version)
Carotid artery stenosis occurs when the carotid arteries narrow. The carotid arteries are major arteries found on each side of the neck. They supply blood from the heart to the brain.
This condition is a major risk factor for ischemic stroke. Ischemic stroke is when blood flow to the brain is blocked due to blood clots. Carotid artery stenosis is a potentially serious condition that requires care from your doctor.

Carotid artery stenosis is caused by the build-up of plaque along the lining of the arteries. This build-up is known as atherosclerosis. Plaque is made up of cholesterol, fat, and other substances.
