angioplasty

 [an´je-o-plas″te]
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.

balloon angioplasty

n.
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

[bəlo̅o̅n′]
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. It is used in treating arteriosclerotic heart disease.

Balloon angioplasty

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. See Atherosclerosis, Cholesterol, Percutaneous transluminal coronary angioplasty. Cf Stenting.

bal·loon ang·i·o·plas·ty

(bă-lūn' an'jē-ō-plas'tē)
Dilation of an obstructed atherosclerotic artery by passage of a balloon catheter through the vessel to the area of disease where the plaque is compressed against the vessel wall.

balloon angioplasty

The use of a BALLOON CATHETER to restore more normal width to an artery narrowed by ATHEROSCLEROSIS. 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 angioplasty

The 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.

Volkhard Lindner, a vascular biologist at the University of Washington in Seattle, calls antisense "an interesting concept" for preventing arterial thickening after balloon angioplasty But he cautions that Rosenberg's team has not proved that the antisense compound specifically blocks c-myb without interfering with other genes.
Serruys stated, "Blood flow measurements made immediately after balloon angioplasty may predict which patients are at risk of major adverse clinical events within six months of angioplasty and therefore may be useful in determining when stenting is appropriate.

Unlike balloon angioplasty, in which a balloon inflated in the artery tears, splits and stretches the plaque, the shaver removes the plaque and leaves a smooth wall, which may prevent the renarrowing that often occurs with angioplasty.
Preverex consists of the same drug incorporated into microparticles and is being developed to inhibit smooth muscle proliferation and migration, complications associated with balloon angioplasty that are believed to account for approximately an additional 25 percent of restenosis.
