Angioplasty/Stent Placement

An Angiogram is a specialized x-ray procedure that looks at the arterial blood vessels to identify any abnormalities. The arteries most frequently examined are the arteries found in the legs, abdomen, head and neck.

The angiogram is done by placing a small catheter in a blood vessel, usually through a small nick in the skin. The catheter is placed in the artery that is to be examined, and the Interventional Radiologist injects a small amount of a contrast agent to make the arteries visible on X-ray.

If you have a blockage in the artery, the Interventional Radiologist will insert a small balloon attached to a catheter, into your artery. He will use X-ray to help guide the catheter to the area of the blockage. The balloon is inflated to open the artery up. Sometimes a tiny mesh-like tube, called a stent, is inserted to hold the blood vessel open. Once the artery has been enlarged, the balloon and catheter will be removed.
