Guide To Venous Leg Ulcers

Venous leg ulcers commonly affect many people in the UK, particularly older adults. These slow-healing wounds form when leg veins struggle to circulate blood efficiently, leading to increased pressure and skin damage. If left untreated, venous leg ulcers can become chronic and significantly impact mobility and quality of life.

What Are Venous Leg Ulcers?

Venous leg ulcers are open wounds that typically appear on the lower legs, most commonly around the ankle. They result from chronic venous insufficiency (CVI), a condition in which the veins fail to return blood to the heart effectively. Fluid accumulates in the tissues, leading to skin breakdown and ulcer formation.

How Common Are They?

In the UK:

Around 1 in 500 people will experience a venous leg ulcer at some point in their lives.
The risk increases with age, with 1 in 50 individuals over 80 developing an ulcer.
Women are more likely to be affected than men, particularly those who have had multiple pregnancies.

Causes and Risk Factors

Venous leg ulcers are caused by poor circulation, which leads to increased pressure in the veins. This weakens the skin and makes it more prone to damage.

Causes:

Varicose veins – Damaged veins that struggle to transport blood efficiently.
Deep vein thrombosis (DVT) – Blood clots that damage vein valves.
Obesity – Excess weight increases pressure on the veins.
Prolonged standing or sitting – Reduces circulation and increases strain on the veins.
Leg injuries or surgeries – Can weaken vein function.
Pregnancy – Increased blood volume and hormonal changes contribute to vein problems.

At Risk:

Older adults (over 65).
Family history of venous disease.
Previous leg ulcers.
Sedentary lifestyle or jobs requiring long hours of standing.

Recognising the Symptoms

Venous leg ulcers often start as small wounds or discoloured patches of skin that worsen over time. Symptoms Include:

Swelling in the lower leg and ankle.
Brown or reddish skin discolouration.
Itchy, dry, or thickened skin (venous eczema).
Aching, heaviness, or discomfort in the legs.
Open wounds with yellowish discharge.
Hardened skin around the ulcer (lipodermatosclerosis).

Without treatment, venous ulcers can become infected, leading to increased pain, swelling, and a foul-smelling discharge.

Diagnosis and Medical Assessment

A healthcare provider will assess a venous leg ulcer using the following methods:

Physical Examination

The ulcer’s size, depth, and condition will be examined to determine the best course of treatment.

Doppler Ultrasound

This test measures blood flow in the veins and helps detect venous insufficiency.

Ankle-Brachial Pressure Index (ABPI)

A test to rule out arterial disease may require different treatment approaches.

Treatment Options

Treating venous leg ulcers involves wound care, improving circulation, and addressing underlying venous issues.

1. Compression Therapy

Compression is the gold standard treatment for venous leg ulcers.

Compression bandages or stockings help improve circulation, reduce swelling, and speed up healing.
Most ulcers heal within 3 to 4 months with consistent compression therapy.

2. Wound Care and Dressings

Keeping the ulcer clean and covered prevents infection and promotes healing.

Foam dressings absorb excess fluid.
Antimicrobial dressings help manage infections.
Hydrocolloid dressings maintain moisture to support skin repair.

3. Medications

Antibiotics – Only prescribed if an infection is present.
Anti-inflammatory drugs – Help reduce swelling and pain.
Aspirin or pentoxifylline – May be recommended to improve healing.

4. Surgical and Minimally Invasive Procedures

For ulcers linked to varicose veins or severe venous insufficiency, additional treatments may be required:

Endovenous Laser Therapy (EVLT) – Uses laser energy to close faulty veins.
Radiofrequency Ablation (RFA) – Similar to EVLT but uses heat energy.
Foam Sclerotherapy – Injects a special foam to collapse problem veins.
Surgical Vein Stripping – Removes severely damaged veins in extreme cases.

Preventing Venous Leg Ulcers

To reduce the risk of developing venous ulcers, specific lifestyle changes and medical interventions can be beneficial.

Compression Therapy

Wearing compression stockings daily can support vein function and prevent blood pooling.

Regular Exercise

Low-impact activities such as walking, cycling, and swimming improve circulation and strengthen leg muscles.

Leg Elevation

Raising the legs above heart level for 30 minutes daily can prevent fluid accumulation.

Healthy Weight Management

Maintaining a healthy BMI reduces pressure on the veins and improves circulation.

Skincare and Hygiene

Moisturise daily to prevent dryness and cracking.
Avoid tight clothing that may restrict circulation.
Check your legs regularly for signs of skin damage or swelling.

Taking Control of Venous Health

Managing venous leg ulcers requires ongoing care and healthy lifestyle choices. While most ulcers heal with treatment, recurrence is common if the underlying venous disease is not addressed.

If you experience persistent swelling, pain, or a slow-healing wound, it’s essential to consult a vascular specialist. Early intervention can prevent complications and ensure the best possible outcome.
