Overview

Peripheral arterial disease is commonly divided in the Fontaine stages, introduced by Dr René Fontaine in 1954. A more recent classification by Rutherford consists of three grades and six categories. In addition, the American College of Cardiology/American Heart Association (ACC/AHA) uses a symptoms-based classification (absence of symptoms, claudication, critical limb ischemia and acute limb ischemia), in their guidelines.

Classification

Fontaine Stages

• Stage I: asymptomatic
• Stage II a: mild claudication
• Stage II b: moderate to severe claudication for relatively shorter distances
• Stage III: ischemia rest pain
• Stage IV: ulceration or tissue loss (gangrene)

Rutherford Categories

• Grade 0, Category 0: asymptomatic
• Grade I, Category 1: mild claudication
• Grade I, Category 2: moderate claudication
• Grade I, Category 3: severe claudication
• Grade II, Category 4: ischaemia rest pain
• Grade III, Category 5: minor tissue loss
• Grade IV, Category 6: major tissue loss.

Shown below is an image showing the difference between Fontaine's and Rutherford's classification.

Classification of PAD

Classification Used in American College of Cardiology/American Heart Association (ACC/AHA) Practice Guidelines

• Absence of symptoms
• Claudication
• Critical/chronic limb ischaemia
• Acute limb ischaemia
