percutaneous transluminal angioplasty
Also written as: PTA — Percutaneous Transluminal Angioplasty
A minimally invasive procedure to widen narrowed blood vessels using a balloon catheter inserted through the skin.
Full Definition
Percutaneous transluminal angioplasty (PTA) is a catheter-based intervention where a balloon is inflated inside a stenotic vessel to compress plaque against the vessel wall, restoring luminal diameter. The procedure is performed through a small skin puncture, typically in the groin or wrist, avoiding the need for open surgery. PTA is commonly used to treat peripheral artery disease, coronary artery stenosis, and other vascular obstructions. Success rates and durability vary depending on vessel location, lesion characteristics, and patient factors.
Usage
Usage note: Always specify the target vessel when referring to PTA procedures in medical documentation.
