How common is vascular surgery for claudication in the UK?
Vascular surgery for intermittent claudication is relatively uncommon in the UK because most patients are successfully managed through conservative treatments such as supervised exercise and medication. In the UK healthcare system, only about 20% of patients with claudication ever require a surgical intervention. For those who do undergo a procedure, the vast majority receive minimally invasive endovascular treatments like angioplasty rather than traditional open bypass surgery. In 2026, the clinical focus remains on avoiding surgery unless the symptoms are severely lifestyle limiting or progress to a more dangerous stage.
Peripheral Vascular Disease (PVD) affects a significant portion of the UK population, particularly those over the age of 60. While claudication is the most frequent symptom, it is generally a stable condition that does not immediately threaten the limb. Because the risks of surgery often outweigh the benefits for mild cases, National Institute for Health and Care Excellence (NICE) guidelines prioritize non operative care. This article examines the frequency of vascular procedures, the types of operations performed, and the clinical criteria for referral in the modern NHS.

Frequency of surgical intervention
In the UK, only a small minority of people with claudication will ever need to see the inside of an operating theatre. Clinical data suggests that for every 100 patients diagnosed with intermittent claudication, approximately 75 will stay stable or see an improvement in their symptoms using exercise and medication alone. Only about 10 to 20 percent of patients experience worsening symptoms that might lead to a surgical discussion.
Statistics from NHS England indicate that around 23,000 revascularisation procedures are performed annually for all stages of peripheral arterial disease. For patients specifically with claudication, the procedures are only recommended if their walking distance is so reduced that it threatens their employment or prevents them from carrying out basic daily tasks. This selective approach ensures that surgical resources are reserved for those with the greatest clinical need.
The move toward minimally invasive procedures
When a procedure is necessary, there has been a significant shift in how these are performed. Over the last two decades, the number of minimally invasive endovascular procedures like balloon angioplasty has risen by more than 40 percent. In contrast, the number of major open surgical procedures like bypass has remained relatively flat or decreased in proportion to the total number of interventions.
| Procedure Type | Typical Annual Volume (England) | Trend in 2026 |
| Endovascular (Angioplasty) | ~15,000 to 16,000 | Increasing |
| Open Surgery (Bypass) | ~7,000 to 8,000 | Stable |
| Total Revascularisations | ~23,000+ | Increasing with age |
This trend is driven by the fact that angioplasty has a much lower risk profile and a faster recovery time. In many UK vascular centres, approximately half of all angioplasties performed are for lifestyle limiting claudication, while the other half are for the more severe stage known as critical limb ischaemia.
Why surgery is not the first choice
The reason vascular surgery is not more common for claudication is that the disease itself is often benign in terms of limb loss. Only 1 to 2 percent of people with claudication will eventually require an amputation within five years. Because surgery always carries a risk of complications, such as blood clots or infection, clinicians prefer to use methods that do not involve making incisions unless absolutely necessary.
NICE guidelines are very clear that surgery should only be offered when supervised exercise has not resulted in a satisfactory improvement. Furthermore, it is very unlikely that a patient who continues to smoke will be offered a surgical intervention for claudication in the UK. This is because smoking significantly increases the chance that a new stent or bypass will block up very quickly, making the risks of the surgery much higher than the potential benefits.
Triggers for surgical referral
While conservative care is the priority, there are certain clinical triggers that will lead a GP to refer a patient for a surgical assessment. These markers indicate that the claudication is no longer manageable through walking and medication.
Clinical Triggers
Walking Distance Limitations
If a patient’s walking distance is reduced to less than 50 metres despite completing a three month exercise programme, a surgical review is typically triggered.
Impact on Employment
If the leg pain prevents a person from performing their job or maintaining their independent living, they are considered a priority for a revascularisation review.
To Summarise
Vascular surgery for claudication is not a common occurrence in the UK because most patients manage their condition through exercise and lifestyle changes. While about 23,000 revascularisation procedures are performed each year in England, many of these are for more advanced disease. For claudication, surgery is a secondary option reserved for those with severe limitations. Minimally invasive angioplasty has become the preferred choice over open bypass due to its safety and faster recovery. . If you experience severe, sudden, or worsening symptoms, especially a cold, pale, or numb foot, call 999 immediately.
Why can’t I just have surgery straight away?
Surgery carries risks and does not stop the underlying disease from progressing. Exercise is often just as effective in the long term with none of the surgical risks.
Is angioplasty considered surgery?
It is a minimally invasive procedure or keyhole surgery. While it is less intensive than a bypass, it is still an invasive intervention.
Will I be seen by a surgeon for my claudication?
Usually, you will be seen by a vascular specialist nurse or a consultant vascular surgeon for your initial assessment to determine if you need an operation.
Does age affect my chances of having surgery?
Age is a factor in surgical fitness. Older patients are more likely to be offered angioplasty because it is less stressful on the heart than major bypass surgery
What if I don’t want surgery?
You are never forced to have a procedure. Most patients with claudication are perfectly safe continuing with conservative management as long as their symptoms do not worsen.
Are these statistics the same for men and women?
Historically, more men have undergone vascular surgery for claudication, but as smoking rates and diabetes prevalence change, the gap between the sexes is narrowing.
How long is the wait for vascular surgery in the UK?
Waiting times vary by region, but because claudication is not usually life threatening, it is categorized as an elective procedure, whereas critical ischaemia is treated as a priority.
