repair or reconstruction of a narrowed or completely obstructed blood vessel. Traditionally, this was performed during open surgery, but in modern practice angioplasty commonly refers to percutaneous transluminal angioplasty (PTA; balloon angioplasty), in which an inflatable balloon, mounted on the tip of a flexible catheter, is placed within the lumen of the affected vessel at the site of the narrowing/blockage, under X-ray control. On inflation of the balloon the lumen is reopened. In an artery this disrupts the intima (which reduces the chances of the stenosis recurring). This procedure may be performed before introducing a vascular stent. Common sites for PTA are coronary, carotid, renal, and leg arteries.
