A procedure in which a slender, metal-mesh tube (stent) is expanded inside the carotid artery to increase blood flow in areas blocked by plaque, carotid stenting is accomplished during balloon angioplasty. The stent is collapsed to a small diameter and put over a balloon catheter. It’s then moved into the area of the blockage. When the balloon is inflated, the stent expands, locks in place and forms a scaffold. This holds the artery open. The stent stays in the artery permanently, holds it open, improves blood flow to the heart muscle and relieves symptoms (usually chest pain).

Carotid stenting is a less invasive alternative to the surgical removal of plaque, known as carotid endarterectomy.
