percutaneous transluminal angioplasty
Minimally invasive procedure using balloon catheter inflation to open narrowed or blocked arteries.
Full Definition
Percutaneous transluminal angioplasty (PTA) is a catheter-based intervention that uses balloon inflation within stenotic or occluded arteries to restore luminal diameter and improve blood flow. The procedure involves percutaneous vascular access, guidewire placement across the lesion, and controlled balloon inflation to compress atherosclerotic plaque against the vessel wall. PTA may be performed alone or in conjunction with stent placement for optimal results. This technique represents a cornerstone of endovascular therapy and appears frequently in treatment protocols, outcome studies, and insurance documentation. Success rates vary by anatomical location and lesion characteristics.
Usage
Usage note: Often abbreviated as PTA in clinical contexts.
