This is an iatroX educational summary of named United States sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Use the named authority, current FDA labeling, applicable state law, payer rules and local protocol where relevant.

Scope of this summary

Adults with asymptomatic PAD, chronic symptomatic PAD including claudication, chronic limb-threatening ischemia or acute limb ischemia. The 2024 guideline addresses lower-extremity atherosclerotic PAD; nonatherosclerotic arterial disease and venous disorders require separate evaluation.

The Bottom Line

  • Detect most PAD through history, vascular examination and a resting ankle-brachial index; interpret physiologic testing in the complete guideline context.
  • Classify the presentation as asymptomatic, chronic symptomatic, chronic limb-threatening ischemia or acute limb ischemia because urgency and treatment differ.
  • Prescribe comprehensive cardiovascular and limb-risk therapy, including antiplatelet or selected antithrombotic treatment, high-intensity statin therapy, blood-pressure and diabetes care, and smoking cessation.
  • Structured exercise鈥攕upervised or structured community/home based鈥攊s a core treatment for chronic symptomatic PAD.
  • Use revascularization to prevent limb loss in chronic limb-threatening ischemia and consider it for function-limiting claudication that persists despite medical therapy and structured exercise.

Practical clinical workflow

1
Ask about exertional and atypical leg symptoms, rest pain, wounds, prior revascularization, tobacco and cardiovascular risk; inspect skin and feet and palpate pulses.
2
Obtain resting ankle-brachial index when PAD is suspected and use additional physiologic or anatomic testing as directed by the source and planned intervention.
3
Start guideline-directed cardiovascular risk reduction, smoking treatment, preventive foot care and structured exercise suited to the clinical subset.
4
Monitor walking function, wounds, medicine adherence, bleeding and new rest symptoms; involve podiatry and wound specialists when needed.
5
Refer chronic limb-threatening ischemia to a multispecialty limb-preservation team and acute limb ischemia immediately for emergency vascular evaluation.

Safety boundaries and escalation

  • Sudden pain, pallor, pulselessness, paresthesia, paralysis or a cold limb suggests acute limb ischemia and is an emergency.
  • Rest pain, nonhealing ulcer, gangrene or infection with ischemia suggests chronic limb-threatening ischemia and requires urgent limb-preservation assessment.
  • Antithrombotic intensity must reflect bleeding risk, revascularization status and the exact 2024 recommendation; do not combine regimens casually.
  • Foot infection, systemic illness or rapidly progressing tissue loss warrants same-day escalation, particularly with diabetes or CKD.

Localization

Use the 2024 multisociety US PAD guideline, local vascular-laboratory standards and limb-preservation network. Exercise-program and revascularization coverage varies by payer; health disparities and transport barriers should be addressed explicitly.
