Carotid Artery
Arteria carótida
Where are the carotid arteries?
The National Cancer Institute (NCI) dictionary says there is a carotid artery on each side of the neck and that each one splits into two branches. The interior branch carries blood to the brain and eyes, and the exterior branch carries blood to the face, tongue, and outside parts of the head. MedlinePlus describes the carotid arteries as two large blood vessels in the neck.
Words used with carotid artery
Carotid artery disease is narrowing or blockage of these arteries, usually because of atherosclerosis. A bruit is a whooshing sound that a doctor hears when listening to the artery with a stethoscope; MedlinePlus names it as one sign of the disease. A transient ischemic attack (TIA), which MedlinePlus calls a "mini-stroke," is another sign: it is like a stroke, but it only lasts a few minutes.
Two treatments are named on the same page: carotid endarterectomy is surgery to remove the plaque, and angioplasty is a procedure to place a balloon and stent into the artery to open it and hold it open.
What it means
A carotid artery is a major artery that carries blood from the heart to the head. There is a carotid artery on each side of the neck, and each one splits into two branches. MedlinePlus describes the carotid arteries as two large blood vessels in the neck that supply the brain and head with blood. In carotid artery disease, the arteries become narrow or blocked, usually because of atherosclerosis, the buildup of plaque. MedlinePlus calls the disease serious because it can block the blood flow to the brain, causing a stroke. It often does not cause symptoms until the blockage or narrowing is severe, and imaging tests can confirm whether a person has it.
