Question: What is the difference between plaque and stenosis?

Carotid stenosis is a narrowing of the carotid arteries, the two major arteries that carry oxygen-rich blood from the heart to the brain. Also called carotid artery disease, carotid stenosis is caused by a buildup of plaque (atherosclerosis) inside the artery wall that reduces blood flow to the brain.

Is stenosis the same as plaque?

Stenosis is a medical term for narrowing of blood vessels in the body due to a buildup of inflammatory substances and cholesterol deposits—called plaque. Two carotid arteries in the neck carry most of the blood flow from the heart to the brain.

What is plaque stenosis?

Carotid artery stenosis is a narrowing of the large arteries on either side of the neck that carry blood to the head, face and brain. This narrowing is usually the result of a build-up of plaque within the arteries, a condition called atherosclerosis.

What is mild carotid artery stenosis?

Mild narrowing ranges from 15% to 49% blockage of the artery. Over time, this narrowing can progress and lead to a stroke. Even if it doesnt progress, mild narrowing is a sign of early blood vessel disease and calls for preventive measures.

What is the difference between stenosis and blockage?
