POBA
Also written as: POBA — Plain Old Balloon Angioplasty
Plain old balloon angioplasty, referring to balloon dilatation without stent placement.
Full Definition
POBA (Plain Old Balloon Angioplasty) is a colloquial term used in interventional cardiology and vascular medicine to describe balloon angioplasty performed without stent implantation. This technique involves inflating a balloon catheter within a stenotic vessel to compress atherosclerotic plaque and restore luminal patency. While the term originated somewhat humorously to distinguish simple balloon angioplasty from more complex interventions, POBA remains a valid therapeutic option for certain lesion types, particularly in small vessels, bifurcations, or when stenting is contraindicated. Modern applications often involve drug-coated balloons for enhanced efficacy.
Usage
Usage note: Informal acronym that should be spelled out in formal documentation; acceptable in procedural notes among specialists.
