angioplasty [an´je-o-plas″te] an angiographic procedure for elimination of areas of narrowing in blood vessels.balloon angioplasty angioplasty in which a catheter" >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" >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.balloon angioplastyn. A procedure in which a catheter with a tiny balloon at the tip is inserted into an artery that has been narrowed by the accumulation of fatty deposits, and the balloon is inflated to widen the arterial opening.balloon angioplasty A minimally invasive procedure in which a catheter with an inflatable balloon tip is inserted through the femoral or brachiocephalic artery and manoeuvred to a previously identified (by angiography) zone of arterial stenosis or occlusion. Once in place, the balloon is inflated, expanding the lumen of the stenosed vessel. BA is used primarily for coronary and carotid arteries, but may be used for other arteries.
Outcomes
Angioplasty successfully opens 90% of occluded coronary arteries; 40% of patients with successful angioplasty suffer recurrent stenosis at the site of balloon inflation.balloon angioplasty Cardiology A minimally invasive procedure in which a catheter with an inflatable balloon tip is inserted through the femoral or brachiocephalic artery and 'snaked' to a previously identified–by angiography zone of arterial stenosis or occlusion.

The catheter is threaded along the artery to the site of the narrowing and the balloon is then inflated, crushing the atherosclerotic plaque into the wall.Balloon angioplastyThe use of a balloon attached to a catheter to widen an artery that has become narrowed. As the balloon is inflated, it opens the artery.Mentioned in: Atherectomy, Coronary StentingAcronymsSeebariumThesaurusSeeangioplasty |
