Angiography > Exams & Procedures > Angioplasty (Percutaneous Transluminal Angioplasty)

This is an arterial procedure similar to an angiogram. It is used to open up stenotic vessels (narrowing in the blood vessels supplying circulation either to the legs or arms). Vessels that are narrowed have usually been identified from a previous angiogram.

The procedure takes about one hour.
