Percutaneous Transluminal Angioplasty (PTA)


Percutaneous transluminal angioplasty (PTA) is a minimally invasive medical procedure used to widen narrowed or obstructed blood vessels, typically caused by conditions such as atherosclerosis. During PTA, a catheter with a small balloon at its tip is inserted into the affected blood vessel, and the balloon is inflated to compress the plaque against the vessel wall, thereby restoring blood flow.
