Can compression socks be used in PVD?
In most cases, compression socks should not be used in patients with significant Peripheral Vascular Disease (PVD) without express clinical guidance. While compression is a standard treatment for venous issues (problems getting blood up to the heart), PVD is an arterial problem (getting blood down to the feet). Applying external pressure to a limb where the arterial blood supply is already restricted can further reduce blood flow, potentially leading to skin breakdown, severe pain, or even tissue death. In 2026, UK clinical standards require a formal assessment of the arterial circulation before any form of compression therapy is considered.
The use of compression in the presence of PVD is a complex clinical decision that depends entirely on the severity of the arterial narrowing. If the blood supply is only mildly affected, light compression might be used to manage swelling, but if the disease is moderate to severe, compression is strictly contraindicated. In the UK healthcare system, the ‘Ankle Brachial Pressure Index’ (ABPI) test is the primary tool used to determine if it is safe to wear these garments. This article explains the physiological risks of compression in PVD, the importance of the ABPI test, and the clinical triggers for avoiding compression altogether in 2026.

The physiological risk of compression
The fundamental goal of compression socks is to squeeze the tissues and veins to help blood return to the heart. This pressure works against the gravity that keeps blood in the lower legs. However, in PVD, the arteries are narrowed by plaque, meaning the blood is already struggling to push through to the feet.
Adding external pressure from a compression sock is like ‘kinking a garden hose’ that is already blocked. This extra resistance can drop the blood pressure in the small vessels of the feet below the level needed to keep the skin alive. In 2026, UK vascular specialists warn that for patients with an already low blood supply, even a ‘light’ compression sock can act as a tourniquet, leading to ischaemic pain and the rapid development of pressure sores or arterial ulcers.
The ABPI test: The gatekeeper of safety
Before any patient in the UK is prescribed compression socks, a nurse or podiatrist must perform an Ankle Brachial Pressure Index (ABPI) test. This test involves using a Doppler ultrasound probe to compare the blood pressure in your ankle to the pressure in your arm.
| ABPI Result | Clinical Meaning | Compression Recommendation |
| 0.9 to 1.3 | Normal arterial flow | Safe to use full compression |
| 0.6 to 0.8 | Mild to moderate PVD | Caution: Use reduced compression only |
| Below 0.5 | Severe PVD/Ischaemia | Contraindicated: No compression allowed |
| Above 1.3 | Calcified arteries | Requires specialist vascular review |
If your ABPI is below 0.5, the blood supply is so critical that any external pressure could cause immediate harm. In these cases, the clinical focus shifts entirely to ‘revascularisation’ (restoring blood flow) rather than managing swelling with socks.
Differentiation: Venous vs Arterial disease
Many patients suffer from ‘mixed’ disease, where they have both poor veins and poor arteries. Understanding which condition is more dominant is vital for safe treatment.
Venous Insufficiency
Characterised by heavy, swollen legs and skin that looks stained or brown. Compression is the ‘gold standard’ here to help the veins work better.
Arterial Disease (PVD)
Characterised by pain when walking, cold feet, and pale skin. Here, compression is a significant risk. If you have both conditions, the arterial disease always takes clinical priority for safety reasons. You must never treat the ‘swelling’ at the expense of the ‘blood supply’.
To Summarise
Compression socks can be dangerous in PVD and should only be used if a clinical assessment, including an ABPI test, has confirmed that your arterial blood supply is strong enough to withstand the pressure. While they are excellent for treating swollen veins, they can worsen the symptoms of narrowed arteries and lead to serious skin damage. If you have been told you have PVD, always seek professional advice before buying or wearing compression garments. If you experience severe, sudden, or worsening symptoms, especially a cold, pale, or numb foot, call 999 immediately.
What happens if I wear compression socks and I have PVD?
You may experience a sudden increase in leg pain, particularly when resting or lying down. In severe cases, you may develop sores or black spots on your toes due to the lack of oxygen.
Can I wear ‘flight socks’ if I have claudication?
Flight socks provide a low level of compression, but you should still check with your doctor first. For most people with stable PVD, they are safe for short durations, but professional advice is always best.
Why did my doctor say no to compression even though my legs are swollen?
Your doctor has likely determined that your arterial disease is the more serious threat. Swelling is uncomfortable, but a lack of blood supply (ischaemia) can lead to the loss of a limb.
Are ‘diabetic socks’ the same as compression socks?
No; diabetic socks are designed to be non-binding and seamless to protect the skin without adding pressure. These are generally safe and recommended for PVD patients.
Can I use compression after my angioplasty?
Once blood flow has been restored and your ABPI has improved, your specialist may reassess you and allow the use of compression to manage any remaining swelling.
What are the signs I should take my compression socks off?
If your toes become numb, cold, blue, or if you feel a burning pain that only stops when the socks are removed, you must take them off immediately and inform your nurse.
Does the length of the sock matter (knee-high vs thigh-high)?
Both types provide compression. Knee-high socks are more common, but the safety risk remains the same for both if the underlying arterial supply is poor.
