Angioplasty and stent placement

Angioplasty (ballooning) is a procedure to open narrowed or blocked blood vessels that supply blood to your legs. These arteries can become blocked with fatty material that builds up inside them. This is called atherosclerosis.


In angioplasty, your blocked artery is widened with a medical "balloon." The balloon presses against the inside wall of your artery to open your artery and improve blood flow. To prevent the artery from narrowing again, a tiny metal stent is placed across the artery wall.

To treat a blockage in your leg, angioplasty can be done in the following arteries:

Before the procedure

Your surgeon will then place a tiny needle into the blood vessel in your groin. Through this needle, a tiny flexible wire will be inserted.

A stent may also be placed in the blocked area. The stent is inserted at the same time as the balloon catheter. It expands when the balloon is blown up. The stent is left in place to help keep the artery open. The balloon and all the wires are then removed.

Why the Procedure is Performed

Symptoms of a blocked peripheral artery are pain, achiness, or heaviness in your leg that starts or gets worse when you walk.

You may not need this procedure if you can still do most of your everyday activities. Your doctor can try medicines and other treatments first.

Reasons for having this surgery are:

Before angioplasty is considered, the doctor will order special tests to show that you have a severe blockage in your blood vessels.
