Angioplasty is the reconstruction of blood vessels that were damaged by cholesterol deposit, disease or injury. In this technique, a ballon catheter is inserted to the narrowed blood vessel and then inflated. The inflation causes the fatty deposits to disappear. After the ballon successfully widened the vessel, it is deflated and withdrawn. Another method to widen the blocked blood vessels is to use a stent. In this procedure a stent is placed around a balloon and inserted inside the vessel with a catheter. After the balloon is positioned properly, the balloon inflates and stent is left around the vessel's wall. The stent remain in the blood vessel permanently in this procedure. Radioactive colours are used to determine the site of damaged blood vessels before Angioplasty is done.
