What Are the Definitions of Arterial Stenosis & Carotid Stenosis?

Q:
What are the definitions of arterial stenosis & carotid stenosis?

A:
What is arterial stenosis?
Arteries transport oxygenated blood to different tissues and organs of the body. This is essential for metabolic activities and sustaining life functions. Any narrowing of an artery will hamper the flow of blood and depending on the extent of the narrowing, known as stenosis, the artery may be partially or completely occluded (blocked).

What is carotid stenosis?
Carotid stenosis, or carotid artery disease, is a narrowing or blockage of the carotid arteries. Located in the side of your neck, your left and right carotids are two large arteries that carry oxygen-rich blood to your brain. You can feel your carotids pulsate when you place your index finger right below the angle of your jaw.

Carotid stenosis is dangerous because it can decrease blood flow to your brain. If blood flow to your brain is interrupted, you can have a stroke. About 800,000 Americans have strokes every year.
