Treatment of peripheral arterial disease (Management of peripheral arterial disease (PAD))

An overview of how narrowed leg arteries are managed — from exercise and medicines to keyhole or surgical treatment — to ease symptoms and protect the heart and limbs.

✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review

In short

PAD is narrowed leg arteries and a warning sign of wider artery disease, so the first aim is protecting your heart and brain — not just the leg.
Stopping smoking, a supervised exercise programme and medicines (antiplatelet and statin) are the foundation and help many people without any procedure.
Angioplasty or bypass surgery is added for severe symptoms or a threatened limb, but improves blood flow rather than curing the disease.
Sudden, severe leg pain, coldness, paleness or a non-healing wound needs urgent assessment, as the limb may be at risk.

A plain-English summary. The detail — including risks and recovery — is below.

How is peripheral arterial disease treated?

Peripheral arterial disease (PAD) is narrowing of the arteries that supply the legs, caused by fatty build-up (atherosclerosis) — the same process that affects the heart. The commonest symptom is intermittent claudication: a cramping pain in the calf, thigh or buttock that comes on with walking and eases with rest. In more severe disease, there can be pain at rest, slow-healing wounds, or a threat to the limb.

Treatment has two goals, and the first matters most. The first is to protect your heart, brain and life, because PAD is a warning sign of widespread artery disease and a higher risk of heart attack and stroke. The second is to improve symptoms in the leg.

The foundations are stopping smoking, regular exercise (especially a supervised walking programme), and medicines — usually an antiplatelet such as aspirin or clopidogrel and a statin, plus control of blood pressure and diabetes. For many people, exercise and medicines improve walking without any procedure.

Keyhole treatment (angioplasty) or bypass surgery is added when symptoms are severe, are not helped enough by exercise and medicines, or when the limb is threatened. Procedures can improve blood flow but do not cure the underlying disease, so the foundations continue for life.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Stopping smoking

The single most important step. It slows the disease, lowers the risk of heart attack and stroke, and improves how well any treatment works. Support and medicines to quit are available.

Supervised exercise programme

Structured walking, often around 2 hours of supervised exercise a week for about 3 months, walking to near-maximal pain then resting. This can meaningfully improve walking distance for claudication.

Medicines

Usually an antiplatelet (such as aspirin or clopidogrel) and a statin to lower cardiovascular risk, plus treatment for blood pressure and diabetes. Naftidrofuryl may be tried for claudication if exercise is not enough.

Angioplasty and stenting

A keyhole way of widening a narrowed artery, used when symptoms are severe or not helped enough by exercise and medicines, and the narrowing is suitable.

Bypass surgery

An operation to reroute blood around a blockage, used when angioplasty is unsuitable or has failed, or for a threatened limb. More durable but a bigger procedure.

Wound and limb care

For severe disease, careful wound care, pain control and a vascular team assessment to try to save the limb, with amputation considered only when a limb cannot be saved.

First-line care vs procedures for PAD

Point	Exercise and medicines	Angioplasty or surgery
Main role	Foundation for everyone	Added for severe or unresponsive disease
Protects heart and brain	Yes, strongly	No — procedures treat the leg, not overall risk
Improves walking	Often, over weeks	Can improve blood flow more quickly
Recovery	None	Keyhole quick; surgery weeks to months
Cures the disease	No, but slows it	No — disease can progress

Procedures do not replace the foundations. Stopping smoking, exercise and medicines continue whether or not you have angioplasty or surgery.

Preparing for your treatment

Expect an assessment of your circulation, often including an ankle-brachial pressure index (ABPI) and sometimes scans of the arteries.
Be ready to discuss smoking honestly — stopping is the most powerful single change and support is available.
Bring a full list of your medicines, including for blood pressure, cholesterol and diabetes.
Ask to be referred to a supervised exercise programme if you have claudication.
Mention any rest pain, non-healing wounds or colour changes in the foot, as these suggest more severe disease needing prompter attention.
Have your blood pressure, cholesterol and diabetes reviewed, as controlling these protects your heart and brain.
Think about what matters most to you — for example, walking further, healing a wound, or avoiding surgery — so the plan fits your goals.

What happens

Management usually starts with a clinic assessment. The clinician asks about your symptoms, examines the pulses and skin in your legs and feet, and often measures the blood pressure at the ankle compared with the arm (ABPI) to gauge how reduced the flow is. Scans may be arranged to map any narrowing.

For most people with claudication, the first plan is stopping smoking, a supervised exercise programme, and medicines to lower cardiovascular risk and control blood pressure and diabetes. You are then reviewed to see how your walking and symptoms respond, usually over a few months.

If symptoms remain severe and limiting despite this, or if the disease is severe enough to threaten the limb, you are assessed for angioplasty or bypass surgery — often by a vascular team that weighs the options together. Throughout, the foundations of smoking cessation, exercise and medicines continue.

Is this treatment right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

Treating PAD as a leg-only problem and ignoring the higher risk of heart attack and stroke.
Jumping to a procedure for mild claudication before trying exercise and medicines.
Compression bandaging for a leg ulcer without first checking the arterial supply, which can be harmful if arteries are badly narrowed.
Relying on medicines alone while continuing to smoke, which undermines the whole plan.

Delay or rearrange if…

You have an active infection or are acutely unwell (non-urgent procedures may wait).
Your blood pressure or diabetes is poorly controlled and can be improved first.
You have not yet been offered a supervised exercise programme for claudication.
Key tests or scans needed to plan treatment are not yet available, and the limb is not threatened.

Alternatives to discuss

Best medical treatment and a supervised exercise programme as first-line care.
Angioplasty and stenting for suitable narrowings when symptoms are not helped enough.
Bypass surgery when angioplasty is unsuitable or has failed, or for a threatened limb.
For an unsalvageable limb, honest discussion of amputation as sometimes the safer option, decided with a vascular team.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Benefits

Lowers the risk of heart attack and stroke, which is the most important benefit
Can improve walking distance and ease cramping pain, especially with exercise and stopping smoking
Slows progression of the artery disease
Procedures, where needed, can restore blood flow to relieve rest pain or help wounds heal
A clear plan can help you avoid unnecessary procedures while keeping the limb safe

Risks & complications

More common

Symptoms improving slowly, and exercise being uncomfortable at first as you walk into pain
Side effects of medicines, such as muscle aches with statins or stomach upset with antiplatelets
Needing to keep up changes long term, which can be hard
Symptoms returning or worsening if smoking continues or the disease progresses

Less common

Bleeding or bruising from antiplatelet medicines
Disease progressing to rest pain or non-healing wounds despite treatment
Procedure-related risks if angioplasty or surgery becomes necessary (covered in those guides)
Other artery problems coming to light, such as heart or carotid disease

Rare but serious

A sudden blockage causing acute, severe leg symptoms — a medical emergency
Critical limb ischaemia threatening the limb
Loss of the limb (amputation) when the circulation cannot be restored

The biggest risk in PAD is not the leg itself but the higher chance of heart attack and stroke, which is why cardiovascular protection comes first. For the leg, the main concerns are the disease progressing and, in severe cases, a threat to the limb. Tell your clinician promptly about rest pain, a non-healing wound, or a sudden cold, pale, painful leg, as these change the urgency.

Published figures to discuss

Outcomes in PAD depend heavily on smoking and on control of blood pressure, cholesterol and diabetes. Most people with claudication stay stable or improve with treatment, and only a minority progress to severe disease or a threatened limb. Useful, source-defensible single percentages for 'PAD treatment' overall are limited, so the figures here are deliberately broad and qualitative; procedure-specific rates are given in the angioplasty and bypass guides.

Figure	Reported range	How to interpret it	Source / confidence
Progression to severe limb-threatening disease	A minority of people with claudication over time	Risk is much higher in people who continue to smoke or have poorly controlled diabetes.	NHS — Peripheral arterial disease (PAD)nhs.ukSource-linked context
Heart attack or stroke	Raised compared with people without PAD	PAD is a marker of widespread artery disease; cardiovascular protection is the priority.	Guide sourcesClinical context
Benefit from supervised exercise for claudication	Often clinically meaningful over about 3 months	Exercise therapy, smoking cessation, statin and antiplatelet/risk-factor treatment are first-line for many people.	NHS — Peripheral arterial disease (PAD)nhs.ukSource-linked context
Re-narrowing or need for repeat procedure after angioplasty or stenting	Common over time, varying by artery, lesion length and smoking/diabetes status	Revascularisation improves blood flow but does not cure the underlying artery disease.	Guide sourcesClinical context

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

PAD is a long-term condition rather than a one-off treatment, so 'afterwards' means ongoing management — reviewing symptoms, keeping up exercise and medicines, and acting on any warning signs.

First weeks

You start or adjust medicines and, ideally, begin a supervised exercise programme. Walking may feel harder before it feels better as you exercise into pain.

Around 3 months

Walking distance is reassessed after a course of supervised exercise. Many people notice they can walk further with less pain.

Ongoing reviews

Your symptoms, blood pressure, cholesterol and diabetes are reviewed periodically, and your medicines adjusted as needed.

If symptoms worsen

Returning or worsening symptoms, rest pain or a non-healing wound prompt reassessment and possible referral for angioplasty or surgery.

After any procedure

If you have angioplasty or surgery, you follow that procedure's recovery, then return to the same foundations of exercise, medicines and not smoking.

What's normal — and not a worry

Walking feeling harder at first as you exercise into the pain, then gradually improving
Symptoms that vary day to day depending on pace, terrain and the weather
Needing time to get used to new medicines
No immediate change in overall risk — the benefit of medicines and stopping smoking builds over time

Aftercare

Stop smoking and use support to stay stopped — the single most important step.
Keep walking regularly, ideally following a supervised exercise programme, walking into discomfort then resting.
Take your antiplatelet and statin every day, and blood-pressure and diabetes medicines as prescribed.
Look after your feet: check daily for cuts or sores, keep them clean, and get foot wounds seen early.
Attend reviews of your symptoms, blood pressure, cholesterol and diabetes.
Eat a balanced diet, keep to a healthy weight and limit alcohol.
Seek help promptly for rest pain, a non-healing wound, or a sudden cold, pale or painful leg.

Before your treatment

Smoking-cessation support arranged if you smoke
Referral to a supervised exercise programme requested
Medicines (antiplatelet, statin, others) understood and to hand
A plan for daily foot checks, especially if you have diabetes
Blood pressure, cholesterol and diabetes review booked
Knowledge of warning signs and who to contact urgently

⚠ Get urgent help if…

Sudden, severe leg pain with the leg becoming cold, pale or numb — a possible blocked artery; seek urgent help
Pain in the foot at rest, especially at night, that is new or worsening
A wound, ulcer or blackened area on the foot or leg that is not healing
Spreading redness, swelling, heat or discharge around a foot wound (possible infection)
Fever or feeling generally very unwell with a foot wound
Chest pain or stroke symptoms (face droop, arm weakness, slurred speech) — call 999

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A good outcome is a lower risk of heart attack and stroke and, for the leg, being able to walk further with less pain or having a wound heal. For many people with claudication, exercise and medicines achieve worthwhile improvement without any procedure.

Management controls the disease rather than curing it. Arteries can narrow further over time, and symptoms can return, so the plan is reviewed and adjusted. Success is best judged against your own goals — walking distance, comfort, healing and avoiding unnecessary procedures — rather than a single test result.

How long it lasts

PAD is lifelong. How it progresses depends heavily on whether you smoke and how well blood pressure, cholesterol and diabetes are controlled. The protection from medicines and stopping smoking continues for as long as you keep them up. Improvements from exercise also fade if walking stops, so staying active matters long term. Some people remain stable for years; others progress and need procedures.

Related tests, treatments or support

Treatment of PAD brings together several strands at once: stopping smoking, supervised exercise, medicines to protect the heart and brain, and control of blood pressure and diabetes. Because the same disease affects other arteries, your care often overlaps with heart and stroke prevention, and sometimes with treatment of carotid (neck) artery disease.

Follow-up & long-term care

You will usually be reviewed in primary care or a vascular clinic to check symptoms, walking distance and your risk factors, with medicines adjusted over time. If symptoms worsen or the limb is threatened, you may be referred for angioplasty or surgery. Foot wounds in people with diabetes need prompt review, often by a specialist foot team.

Do not smoke, and keep using support to stay stopped
Keep walking and stay active, ideally following an exercise programme
Take antiplatelet and statin medicines, and others, as prescribed
Keep blood pressure, cholesterol and diabetes well controlled
Check your feet daily and get wounds seen early
Attend reviews and report returning or worsening symptoms

Repeat, follow-on and what comes next

Treatment is adjusted over time as symptoms and risk factors change.
Medicines may be switched or added, and exercise programmes repeated.
Procedures, if done, can need repeating as arteries narrow again.
Worsening symptoms or a threatened limb prompt re-referral to a vascular team.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

Active, repeated support to stop smoking.
Access to a supervised exercise programme and clear self-management advice.
A clear plan for antiplatelet, statin and other medicines, with regular review.
Structured monitoring of blood pressure, cholesterol and diabetes.
Clear warning signs and an easy route back to the vascular team if the limb is threatened.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

Whether care is mainly medical (medicines and exercise) or involves procedures
Access to a supervised exercise programme
Specialist consultations and circulation tests (such as ABPI) and scans
Ongoing medicines and monitoring of blood pressure, cholesterol and diabetes
If needed, the cost of angioplasty or surgery (covered in those guides)
Foot care and wound management for more severe disease

Make sure your written quote includes

Consultation fees and which circulation tests and scans are included
Whether a supervised exercise programme is offered and how it is delivered
Ongoing medicine and monitoring arrangements
If a procedure is recommended, a separate written quote covering it
Follow-up appointments and how returning symptoms are reviewed
What happens if the disease progresses or a complication occurs

On the NHS? Assessment, exercise programmes, medicines and procedures for PAD are routinely provided on the NHS; private care is sometimes used for speed or choice but follows the same principles.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Questions to ask your medical professional

Take this to your consultation. A good specialist will welcome every one of these.

How severe is my PAD, and is my limb at any risk?
Can I be referred to a supervised exercise programme?
Which medicines should I be on to protect my heart and brain, not just my legs?
Would a procedure help me, or should I try exercise and medicines first?
What are my blood pressure, cholesterol and diabetes targets?
What symptoms should make me seek urgent help?
Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
Will you be the specialist who carries out my treatment, and who looks after me afterwards?
What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
What does a realistic result look like — and what can this treatment not achieve?
What are my options, including waiting, doing nothing for now, or choosing a different approach?
Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
What is the total cost in writing, including any follow-ups, and how much time do I have to decide?

Frequently asked questions

Is PAD treatment available on the NHS?

Yes. Assessment, exercise programmes, medicines and procedures for PAD are routinely provided on the NHS. Private care is sometimes used for speed or choice, but the principles of treatment are the same.

Do I really need a procedure, or can exercise and medicines help?

For many people with claudication, stopping smoking, a supervised exercise programme and medicines improve walking without any procedure. Angioplasty or surgery is usually added only when symptoms are severe and not helped enough, or when the limb is threatened.

Why is stopping smoking emphasised so much?

Smoking drives the artery disease, raises the risk of heart attack and stroke, and makes every treatment work less well. Stopping is the single most powerful thing you can do for your legs and your life.

Will the cramping pain go away?

It often improves with exercise and stopping smoking, and procedures can help when needed, but PAD is controlled rather than cured. Symptoms can return if the disease progresses or you stop the foundations.

What does the exercise programme involve?

A supervised walking programme, often around 2 hours a week for about 3 months, where you walk until the pain is near its limit, rest until it eases, then walk again. This stop-start method gradually builds your walking distance.

When is it an emergency?

A sudden, severe, cold, pale or numb leg can mean an artery has blocked acutely and needs urgent treatment. Rest pain and non-healing foot wounds also need prompt assessment, as the limb may be at risk.
