Fontaine classification
Pronunciation: fon-TAYN
Staging system for peripheral arterial disease based on symptom severity and functional limitation.
Full Definition
The Fontaine classification is a widely used clinical staging system that categorizes peripheral arterial disease severity into four progressive stages based on symptom presentation and functional capacity. Stage I represents asymptomatic disease, Stage II covers intermittent claudication (subdivided into IIa and IIb based on walking distance), Stage III indicates rest pain, and Stage IV encompasses tissue necrosis or gangrene. This classification system provides standardized terminology for clinical communication and research, requiring editors to understand the specific criteria and implications of each stage when reviewing vascular medicine literature.
Usage
Usage note: Often used interchangeably with Rutherford classification; ensure consistency within documents.
