Understanding PT Stent Insertion

Percutaneous transluminal angioplasty (PTA) or stent insertion is a minimally invasive procedure used to open narrowed or blocked arteries. It is used to restore blood flow and treat conditions like atherosclerosis in various parts of the body, including the legs, kidneys, and heart (in which case it is also called coronary angioplasty). Using real-time imaging, a catheter is guided through a small incision in the wrist or groin to the affected artery. A balloon is then inflated to widen the vessel, followed by the placement of a small metal stent to keep the artery open and ensure continuous blood flow.
