Rutherford Classification of Peripheral Arterial Disease

Standard staging system for chronic lower-extremity ischaemia (Rutherford 1997). Categories 0–6 from asymptomatic to major tissue loss. Used alongside ABPI and Fontaine to guide intervention timing per ESVS 2024 and NICE CG147.

Score interpretation

Category 0 — Asymptomatic 0

→ Risk-factor optimisation: smoking cessation, statin, antiplatelet, BP and glycaemic control; supervised exercise if subclinical PAD. Annual review.

Categories 1–3 — Intermittent claudication 1–3

→ Best medical therapy + supervised exercise programme (NICE CG147). Consider revascularisation (endovascular first) if lifestyle-limiting after 3 months of optimised therapy.

Categories 4–6 — Chronic limb-threatening ischaemia (CLTI) 4–6

→ Urgent vascular referral. ABPI/TBI, duplex, CTA. Revascularisation (endo or open) within 2 weeks per ESVS; analgesia, pressure-area care, antibiotics if infected ulcer. Consider WIfI staging and amputation MDT if unsalvageable.

Interpretation bands for the Rutherford PAD. Apply clinical judgement and local guidance.
