What's carotid stenosis?

Narrowing of artery

Open-uri20120827-27110-wjoo9e
The term refers to the narrowing of the carotid arteries which supply blood to the brain. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery. When the carotid arteries are obstructed, you are at an increased risk for a stroke, the third leading cause of death in USA.
