balloon angioplasty. [bÉloÌoÌnâ²]. a method of dilating or opening an obstructed blood vessel by threading a small, balloon-tipped catheter into the vessel. The balloon is inflated to compress arteriosclerotic lesions against the walls of the vessel, leaving a larger lumen, through which blood can pass.
Once the diagnosis is made, generally through scans that are designed to take clear pictures of abdominal arteries, the problem is eliminated by opening the artery through angioplasty, a balloon-tipped tube inserted through a surface artery and advanced to the site of blockage where the balloon is inflated.
