Definition of angioplasty in English English dictionary
The mechanical widening of a narrowed or totally obstructed blood vessel generally caused by atheroma
—The use of surgery to make a damaged blood vessel function properly again; may involve widening or reconstructing the blood vessel
is a procedure where a balloon catheter is inserted into an artery blocked by a plaque The catheter is then inflated to flatten the plaque against the wall of the artery Angioplasty is intended to make a wider opening for blood to flow However, following angioplasty, endothelial cells lining the vessel are disrupted and "fatty streaks" (regions of accumulated cholesterol, especially oxidized cholesterol, immune cells and platelets) begin to develop Ultimately, these fatty streaks can cause a secondary narrowing or constriction of the blood vessel, known as restinosis
a procedure performed to open narrowed blood vessels by insertion of a balloon catheter to mechanically reduce obstructions; often followed by placement of stents to provide mechanical support to prevent collapse, provide strengthening and/or reduce restenosis
A procedure using a deflated balloon on the end of a catheter used to widen narrow arteries
dilatation of a diseased blood vessel (usually performed by passing an instrument into the vessel via a wire)
A nonsurgical technique for treating diseased arteries by temporarily inflating a tiny balloon inside an artery The balloon is inflated several times to attempt to stretch the cholesterol block so that it no longer causes a significant obstruction Also known as percutaneous transluminal coronary angioplasty (PTCA)
{i} surgical operation of the blood vessels in which a balloon is inserted into a vessel and inflated in order to clear clogged arteries (Medicine)
Balloon dilatation a procedure where an arterial blockage is expanded, or dilated, with a balloon The procedure takes place under x-ray guidance in the cardiac catheterization laboratory Expansion of the obstructing plaque can, in some cases, restore the flow channel and relieve symptoms of angina
The surgical repair of a blood vessel A balloon angioplasty is a noninvasive procedure where a balloon-tipped catheter is introduced into a diseased blood vessel As the balloon is inflated, the vessel opens allowing for improved flow of blood
An invasive procedure to enlarge a narrowed artery Coronary angioplasty is an operation to enlarge a narrowed coronary artery
Therapeutic opening of a blocked blood vessel. Usually a balloon is inflated near the end of a catheter (see catheterization) to flatten plaques (see atherosclerosis) against an artery's wall. Performed on a coronary artery, angioplasty is a less invasive alternative to coronary bypass surgery in the treatment of coronary heart disease. Complications, including embolisms and tearing, are rare and results are excellent, but plaques tend to build up again after the procedure. Angioplasty is also used to expand a severely obstructed heart valve
(also known as balloon angioplasty): non-surgical alternative to arterial surgery in the heart (see CABG and PTCA) and in arteries supplying other parts of the body
Altering the structure of a blood vessel either by a surgical procedure or by opening up the vessel using a balloon-like device attached to a catheter (see CATHETER)
A procedure that opens coronary arteries that have been clogged by fatty plaques caused by coronary artery disease A balloon at the tip of a catheter is inflated inside an artery and presses the plaque against the artery wall Some angioplasty procedures also use a stent to help keep the artery open
alteration of a blood vessel, either surgically or by dilating the vessel using a balloon inside the lumen
An invasive procedure, during which a specially designed balloon catheter with a small balloon tip is guided to the point of narrowing in the artery Once in place, the balloon is inflated to compress the fatty matter into the artery wall and stretch the artery open to increase blood flow to the heart
Reconstitution or reopening of a blood vessel; may involve balloon dilation, mechanical stripping of the inside of the blood vessel, forceful injection of a elastic filamentous protein, or placement of a stent
altering the structure of a vessel by surgical procedure or by dilating the vessel using a balloon
The process of dilating a blood vessel, as by inserting a balloon-tipped catheter (balloon angioplasty)
A balloon procedure to open an obstruction or narrowing of a blood vessel Also known as percutaneaous transluminal coronary angioplasty (PTCA)
a medical procedure usually referring to a catheter technique applied to an artery to open a blockage The procedure done in the coronary artery is often referred to as balloon angioplasty or PTCA
A non-surgical procedure that dilates or opens narrowed arteries The artery is widened when a catheter with a balloon on its tip is passed into the narrowed artery The balloon is inflated and the artery is widened
balloon angioplasty, opening of a blocked or narrowed blood vessel by inserting a balloon-tipped catheter into the vessel and inflating it to compress the fatty buildup inside (Medicine)
