What is carotid artery stenting?

Carotid artery stenting is a procedure in which a small device known as a stent is inserted into the carotid artery in order to reopen the blocked or partially blocked blood vessel.

How does carotid artery stenting work?

During the procedure, a specially designed guide wire with a filter, that acts similar to an umbrella, is placed beyond the area of narrowing in the carotid artery. Once in place, a small balloon is inflated for a few seconds to stretch the artery. Then, the stent is placed in the artery and opens to fit the size of the artery. A second balloon inflation is done to make sure the stent is completely expanded in your carotid artery. The stent stays in place permanently. After several weeks, your artery heals around the stent.
