What is Stent?
Stent
A stent is a small tube inserted into a blocked or narrowed passage in the body, often a blood vessel, to keep it open. It helps restore normal blood flow and can be used in various medical procedures.
Overview
A stent is a medical device used to treat conditions where blood vessels or other passages in the body become narrowed or blocked. It is typically made of metal or plastic and is inserted into the affected area during a procedure called angioplasty. Once in place, the stent expands to hold the passage open, allowing blood to flow freely again. The way a stent works is quite straightforward. During the procedure, a doctor threads a thin tube called a catheter through the blood vessels to reach the blockage. A balloon at the tip of the catheter is inflated to expand the stent, which then stays in place to keep the passage open. This method is commonly used in heart procedures to treat coronary artery disease, where arteries supplying blood to the heart become narrowed. Stents are important because they can prevent serious health issues like heart attacks or strokes by ensuring adequate blood flow. For example, a person with a blocked artery might experience chest pain, but after a stent is placed, they often find relief and can return to normal activities. This procedure is a key part of modern surgery and helps many individuals maintain their health.
