Description

When a stent is placed into the body, the procedure is called stenting. There are different kinds of stents. Most are made of a metal or plastic mesh-like material. However, stent grafts are made of fabric. They are used in larger arteries.

A coronary artery stent is a small, self-expanding, metal mesh tube. It is placed inside a coronary artery after balloon angioplasty. This stent prevents the artery from re-closing.

A drug-eluting stent is coated with a medicine. This medicine helps further prevent the arteries from re-closing. Like other coronary artery stents, it is left permanently in the artery.

Why the Procedure Is Performed

Most of the time, stents are used when arteries become narrow or blocked.

Stents are commonly used to treat the following conditions that result from blocked or damaged blood vessels:

Other reasons to use stents include:
