an angiographic procedure for elimination of areas of narrowing in blood vessels.
balloon angioplasty angioplasty in which a balloon catheter is inflated inside an artery, stretching the intima and leaving a ragged interior surface after deflation, which triggers a healing response and breaking up of plaque.
percutaneous transluminal angioplasty a type of balloon angioplasty in which the catheter is inserted through the skin and through the lumen of the vessel to the site of the narrowing.
percutaneous transluminal coronary angioplasty (PTCA) percutaneous transluminal angioplasty to enlarge the lumen of a sclerotic coronary artery (see accompanying illustration). This provides an alternative to cardiac bypass surgery for selected patients with ischemic heart disease. See also heart.
 Percutaneous transluminal coronary angioplasty (PTCA). A, Balloon-tipped catheter positioned in blocked artery. B, Balloon is centered. C, Balloon expands to (D) compress blockage. E, Artery diameter opened. From Polaski and Tatro, 1996.

per·cu·ta·ne·ous trans·lu·mi·nal an·gi·o·plas·ty (PTA),

an operation for enlarging a narrowed vascular lumen, by inflating and withdrawing a balloon on the tip of an angiographic catheter through the stenotic region; may include positioning of an intravascular endoluminal stent.

percutaneous transluminal angioplasty (PTA)

a procedure for dilating blood vessels in the treatment of peripheral artery disease. Under fluoroscopic guidance a balloon-tipped catheter is inserted into a stenotic artery and the balloon is inflated. The inflated balloon may dilate the artery by stretching its elastic fibers or by flattening accumulation of plaque. See also percutaneous transluminal coronary angioplasty.

(PTA) (pĕr'kyū-tā'nē-ŭs trans-lū'mĕn-ăl an'jē-ō-plas-tē)
An operation for enlarging a narrowed vascular lumen by inflating and withdrawing a balloon on the tip of an angiographic catheter through the stenotic region; may include positioning of an intravascular stent. Used in the treatment of atherosclerotic coronary heart disease and angina pectoris to improve circulation.


surgical repair of blood vessels or lymphatic channels.

percutaneous transluminal angioplasty
dilatation of a blood vessel by means of a balloon catheter inserted through the skin and into the chosen vessel and then passed through the lumen of the vessel to the site of the lesion, where the balloon is inflated to flatten plaque against the artery wall. Called also PCTA.
