angioplasty (n)
English Definitions:
angioplasty (noun)
an operation to repair a damaged blood vessel or unblock a coronary artery
angioplasty (Noun)
The mechanical widening of a narrowed or totally obstructed blood vessel generally caused by atheroma.
Angioplasty
Angioplasty is the technique of mechanically widening narrowed or obstructed arteries, the latter typically being a result of atherosclerosis. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure. The balloon forces expansion of the inner white blood cell/clot plaque deposits and the surrounding muscular wall, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. A stent may or may not be inserted at the time of ballooning to ensure the vessel remains open. The word is composed of the combining forms of the Greek words ἀγγεῖον angīon ‘vessel’/‘cavity’ and πλάσσω plasso ‘form’/‘mould’. Angioplasty has come to include all manner of vascular interventions that are typically performed in a minimally invasive or percutaneous method.
Angioplasty
Angioplasty, is also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive endovascular procedure used to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. A stent may be inserted at the time of ballooning to ensure the vessel remains open, and the balloon is then deflated and withdrawn. Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously. The word is composed of the combining forms of the Greek words ἀνγεῖον angeîon "vessel" or "cavity" (of the human body) and πλάσσω plássō "form" or "mould".
