One of the first questions patients ask me after a PAD diagnosis is: ‘Do I definitely need surgery?’ The answer, in many cases, is no — at least not immediately. Peripheral artery disease has a range of treatment options, and surgery or angioplasty is only one part of the picture. For many patients, particularly those with claudication rather than critical ischaemia, non-surgical management is the appropriate starting point and can produce remarkable results.
Can Peripheral Artery Disease Be Treated Without Surgery?
Yes — for many patients with PAD, particularly those with intermittent claudication, the first-line treatment is non-surgical. This consists of risk factor modification, structured exercise therapy, and best medical therapy. Together, these approaches can significantly improve walking distance, slow disease progression, and reduce cardiovascular risk. Surgical or endovascular intervention is reserved for patients with severe claudication that has not responded to conservative management, or for those with critical limb ischaemia (rest pain or tissue loss).
Non-Surgical Treatments for PAD
1. Supervised Exercise Therapy
Supervised exercise therapy is the single most effective non-surgical treatment for claudication. Structured walking programmes — typically 30–60 minutes of walking 3–5 times per week, pushing to near-maximal claudication pain — stimulate the development of collateral blood vessels, improve muscle metabolism, and can double or triple walking distance over 3–6 months.
2. Stopping Smoking
Stopping smoking is the most important lifestyle change for any PAD patient who smokes. Continued smoking accelerates disease progression, worsens claudication, dramatically increases the risk of critical ischaemia and amputation, and reduces the benefit of any revascularisation procedure.
3. Antiplatelet Medication
Antiplatelet drugs — most commonly aspirin or clopidogrel — reduce the risk of blood clot formation on atherosclerotic plaques. They are prescribed to all PAD patients to reduce the risk of heart attack, stroke, and acute limb ischaemia.
4. Statin Therapy
Statins lower LDL cholesterol and have anti-inflammatory effects on arterial plaques. In PAD patients, statin therapy has been shown to slow disease progression, reduce cardiovascular events, improve walking distance in claudicants, and improve outcomes after revascularisation. All PAD patients should be on a statin unless contraindicated.
5. Blood Pressure and Diabetes Control
Achieving target blood pressure and HbA1c levels slows the progression of atherosclerosis in the leg arteries and reduces the risk of cardiovascular events. ACE inhibitors and ARBs are the preferred blood pressure agents in PAD.
6. Cilostazol
Cilostazol is a phosphodiesterase inhibitor that improves walking distance in claudication by causing arterial vasodilation and inhibiting platelet aggregation. It is the only medication with a specific licence for claudication symptom improvement. In appropriate patients it can meaningfully increase pain-free walking distance.
When Is Surgery or Angioplasty Needed?
- Claudication so severe it significantly impairs quality of life and has not improved with 3–6 months of supervised exercise
- Rest pain — pain at rest always requires vascular intervention, as it signals critical ischaemia
- Tissue loss — any ulcer or gangrene requires revascularisation assessment urgently
- Acute limb ischaemia — a sudden complete arterial occlusion is a vascular emergency requiring immediate intervention
My Clinical Perspective
I always tell my claudication patients: the best thing you can do for your legs right now is walk. Not gentle strolling — structured, progressive walking that challenges the claudication threshold. The evidence for supervised exercise in claudication is as strong as the evidence for angioplasty in terms of walking distance improvement at 12 months. I’ve seen patients go from barely managing 100 metres to walking several kilometres comfortably through exercise alone, combined with smoking cessation and medical therapy.
Warning Signs That Non-Surgical Treatment Is Not Enough
- Rest pain developing despite medical management
- Any new wound on the foot that is not healing
- Worsening claudication to the point that it severely limits daily life despite exercise
- Rapid deterioration of symptoms over days to weeks
⚠️ Important: Non-surgical management is appropriate for claudication, but rest pain and tissue loss always require urgent vascular assessment. Do not manage these conservatively.

Frequently Asked Questions
Can PAD improve on its own?
The atherosclerotic plaques causing PAD do not spontaneously resolve, but symptoms can improve through the development of collateral blood vessels. Supervised exercise is the most powerful stimulus for collateral development. Without active management, PAD tends to progress over time.
How long does supervised exercise take to show results in PAD?
Most patients notice improvement in walking distance within 4–8 weeks of starting a structured exercise programme. Maximum benefit is typically achieved at 3–6 months of consistent training.
Are there any new drug treatments for PAD?
Rivaroxaban at a low dose combined with aspirin has shown benefit in reducing major cardiovascular and limb events in PAD patients. SGLT2 inhibitors and GLP-1 agonists are also showing cardiovascular and peripheral vascular benefit in recent trials.
