Venous Leg Ulcers: What they are, why they happen, and how to recognize them

Venous leg ulcers are chronic open wounds that occur as a result of venous circulation problems. They are one of the most common causes of chronic wounds in adults, particularly in older populations. While they may seem like a minor issue at first, over time they can cause pain, discomfort, and serious complications if not properly addressed.

What is a Venous Ulcer?

A venous ulcer is a skin lesion that develops when there is prolonged high pressure in the leg veins. This excessive pressure hinders the return of blood from the lower limbs to the heart, leading to fluid buildup, inflammation, and eventually a skin breakdown. These ulcers typically appear on the inner part of the leg, just above the ankle.

What causes this condition?

The most common cause is chronic venous insufficiency, a condition where the valves in the veins do not function properly. Normally, these valves help blood flow upward toward the heart and prevent it from flowing backward. When they fail, blood pools in the legs, generating abnormal pressure that over time damages the tissues and leads to ulcer formation.

Risk factors

• Older age, especially over 60
• History of deep vein thrombosis (DVT)
• Prominent varicose veins
• Overweight or obesity
• Multiple pregnancies
• Sedentary lifestyle or standing for prolonged periods
• Previous leg injuries
• Chronic conditions such as hypertension, diabetes, or heart disease

How to recognize a Venous Ulcer

These ulcers have distinct characteristics:

• Often located on the inner leg, near the ankle
• Usually have irregular edges with inflamed or discolored surrounding skin
• The skin around may appear hardened, darkened, or shiny
• Swelling is common in the affected leg
• There may be fluid discharge and a bad odor if infected
• Patients often experience pain, itching, or pressure in the area

How are they diagnosed?

Diagnosis is based on a full clinical evaluation, examining both the appearance of the ulcer and the patient’s medical history. Non-invasive tests such as the Ankle-Brachial Pressure Index (ABPI) or Doppler ultrasound are often used to assess venous function and rule out other causes such as arterial disease or skin disorders.

Can they be prevented?

Prevention is essential, especially for individuals with a history of venous disease or prior ulcers. Effective strategies include:

• Elevating the legs when resting
• Engaging in regular physical activity to promote circulation
• Avoiding prolonged standing or sitting without movement
• Wearing loose clothing and comfortable shoes
• Maintaining a healthy weight
• Quitting smoking, as it affects vascular health
• Taking care of the skin with proper hydration and protection

Why is it important to pay attention?

Venous ulcers are more than skin-deep; they are a visible sign of a more serious vascular issue. If left unmanaged, they can expand, become infected, or lead to serious complications. They also impact quality of life, affecting mobility, rest, and emotional well-being.

In summary

Venous leg ulcers are a warning sign that the venous system isn’t working as it should. Though they appear as simple wounds, their cause is complex and requires medical attention. With the right information, prevention strategies, and follow-up, it is possible to minimize their occurrence and support long-term vascular health.

Now enrolling: Clinical Study for Venous Leg Ulcers

C&R Research Services USA is currently conducting a clinical research study for individuals suffering from venous leg ulcers. If you or someone you know has a non-healing wound in the lower leg, you may qualify to participate.

Participants may receive:

• No-cost medical care and study-related procedures
• Compensation for time and travel
• Access to potential new treatment options
