Angioplasty is a procedure used to open blocked or narrowed blood vessels caused by peripheral arterial disease or other conditions.

The interventional radiologist inserts a very small balloon attached to a thin catheter into a blood vessel through a small nick in the skin. Using x-ray guidance, the catheter is directed to the site of the blocked artery. The balloon is inflated to open the artery.

What is the benefit of angioplasty?

Angioplasty and stenting have generally replaced open surgery and become the preferred first-line treatment because research has shown interventional therapy to be as effective as surgery for many arterial occlusions.
