balloon angioplasty
Also written as: PBA — Percutaneous balloon angioplasty
Interventional procedure using an inflatable balloon to compress arterial plaque and restore vessel patency.
Full Definition
Balloon angioplasty is a minimally invasive cardiovascular procedure that involves the inflation of a balloon catheter within a stenosed artery to compress atherosclerotic plaque against the vessel wall and restore luminal patency. The procedure begins with percutaneous arterial access, followed by guidewire placement across the lesion and positioning of an appropriately sized balloon catheter. Balloon inflation creates controlled arterial injury that results in plaque compression, vessel wall stretching, and often controlled dissection of the intimal layer. Success is measured by residual stenosis reduction and restoration of antegrade flow.
Usage
Usage note: Space between 'balloon' and 'angioplasty'. Often modified with 'plain' to distinguish from drug-coated balloon procedures.
