Causes & Risk Factors
Several factors can contribute to Chronic Venous Leg Ulcers.
The root cause of chronic venous leg ulcers lies in a circulation problem called chronic venous insufficiency.
The root cause of chronic venous leg ulcers lies in a circulation problem called chronic venous insufficiency. Think of your leg veins like a one-way highway designed to carry blood back up to your heart. Tiny valves inside these veins act like traffic lights, opening to let blood flow upward and closing to prevent it from flowing backward. When these valves become damaged or weakened, blood starts to pool in the lower legs instead of returning efficiently to the heart.
This blood pooling creates increased pressure in the veins, much like water backing up behind a dam.
This blood pooling creates increased pressure in the veins, much like water backing up behind a dam. Over time, this excess pressure causes fluid to leak out of the blood vessels and into the surrounding tissues, leading to swelling and inflammation. The skin and underlying tissues don't receive adequate oxygen and nutrients, making them fragile and prone to breaking down. Even minor trauma like a small bump or scratch can then develop into an ulcer that struggles to heal.
Several factors can damage the delicate vein valves and trigger this cascade of problems.
Several factors can damage the delicate vein valves and trigger this cascade of problems. Previous blood clots in the leg veins, known as deep vein thrombosis, can permanently damage valve function. Varicose veins, genetics, prolonged standing or sitting, obesity, and aging all contribute to valve deterioration. Sometimes the valves simply wear out over time, like any mechanical part subjected to constant use and pressure from gravity.
Risk Factors
- History of blood clots in the legs (deep vein thrombosis)
- Varicose veins or family history of vein problems
- Being overweight or obese
- Jobs requiring prolonged standing or sitting
- Previous leg injury or surgery
- Pregnancy, especially multiple pregnancies
- Age over 50 years
- Smoking cigarettes
- High blood pressure
- Diabetes mellitus
Diagnosis
How healthcare professionals diagnose Chronic Venous Leg Ulcers:
- 1
Diagnosing chronic venous leg ulcers typically begins with your doctor examining the wound and asking about your symptoms and medical history.
Diagnosing chronic venous leg ulcers typically begins with your doctor examining the wound and asking about your symptoms and medical history. The location of the ulcer provides important clues - venous ulcers almost always appear on the lower leg, particularly around the inner ankle area. Your doctor will look for other signs of venous insufficiency like skin discoloration, swelling, and varicose veins. They'll also assess the wound itself, noting its size, depth, and appearance of the surrounding tissue.

The most important diagnostic test is a duplex ultrasound, a painless procedure that uses sound waves to create pictures of blood flow in your leg veins.
The most important diagnostic test is a duplex ultrasound, a painless procedure that uses sound waves to create pictures of blood flow in your leg veins. This test can identify damaged valves, blood clots, and areas where blood is flowing backward instead of toward the heart. The ankle-brachial index (ABI) test compares blood pressure in your ankle to blood pressure in your arm to rule out arterial circulation problems, which require different treatment approaches.

Other tests might include blood work to check for diabetes, infection, or clotting disorders.
Other tests might include blood work to check for diabetes, infection, or clotting disorders. In some cases, your doctor may recommend additional imaging studies or refer you to a vascular specialist for further evaluation. A small tissue sample from the wound edge might be taken if the ulcer has an unusual appearance or isn't responding to standard treatment, helping rule out other causes like skin cancer or unusual infections.
Complications
- The most concerning complication of chronic venous leg ulcers is infection, which can range from superficial skin infection to serious deep tissue involvement.
- Signs of infection include increased pain, redness spreading beyond the wound edges, fever, and foul-smelling drainage.
- Without prompt treatment, infected ulcers can lead to cellulitis, bone infection, or in rare cases, life-threatening blood poisoning.
- However, most infections respond well to antibiotics when caught early.
- Long-term complications can significantly impact quality of life if ulcers remain untreated or keep recurring.
- Chronic pain and limited mobility may develop, affecting your ability to work or enjoy daily activities.
- Some people experience permanent skin changes including scarring, ongoing swelling, or areas of hardened skin.
- The emotional toll of dealing with a chronic, visible wound can lead to social isolation and depression.
- Fortunately, proper treatment dramatically reduces the risk of these complications, and most people with venous ulcers can expect good outcomes with appropriate care.
Prevention
- Preventing chronic venous leg ulcers centers on maintaining good circulation and protecting your legs from injury.
- If you have varicose veins or a family history of vein problems, wearing compression stockings during long periods of standing or sitting can help prevent blood from pooling in your legs.
- Regular exercise, particularly activities that work your calf muscles like walking or swimming, acts as a natural pump to push blood back toward your heart.
- Daily leg care becomes especially important if you're at high risk for venous problems.
- Elevating your legs above heart level for 15-30 minutes several times a day can reduce swelling and improve circulation.
- When sitting for long periods, flex your ankles and take frequent breaks to walk around.
- Maintaining a healthy weight reduces pressure on your leg veins, while avoiding tight clothing around your waist and legs prevents circulation restrictions.
- Pay close attention to any changes in your legs and seek prompt medical attention for wounds that don't heal normally.
- Keep your skin moisturized to prevent cracks and protect your legs from injury by wearing appropriate footwear and avoiding activities that might cause bumps or scrapes.
- If you develop swelling, skin discoloration, or aching in your legs, see your doctor before ulcers have a chance to form.
- Early treatment of venous insufficiency can prevent many ulcers from developing in the first place.
The foundation of venous ulcer treatment focuses on improving circulation and reducing the pressure in leg veins through compression therapy.
The foundation of venous ulcer treatment focuses on improving circulation and reducing the pressure in leg veins through compression therapy. Medical-grade compression stockings or bandages apply graduated pressure to the leg, with the highest pressure at the ankle decreasing toward the knee. This external pressure helps push blood back up toward the heart and reduces swelling. Many patients see improvement within weeks of starting proper compression, though complete healing can take several months.
Wound care plays an equally important role in the healing process.
Wound care plays an equally important role in the healing process. Healthcare providers clean the ulcer regularly and apply appropriate dressings to maintain a moist healing environment while protecting against infection. Different types of dressings serve various purposes - some absorb excess drainage, others provide antibacterial protection, and specialized dressings can promote new tissue growth. The specific dressing choice depends on the ulcer's characteristics and stage of healing.
When conservative treatment isn't sufficient, several medical procedures can address the underlying vein problems.
When conservative treatment isn't sufficient, several medical procedures can address the underlying vein problems. Endovenous ablation uses heat or chemical agents to seal off damaged veins, redirecting blood flow to healthier vessels. Sclerotherapy involves injecting a solution that closes problematic veins. For severe cases, surgical procedures like vein bypass or valve repair might be recommended. These interventions can significantly improve healing rates and reduce the risk of ulcer recurrence.
Promising new treatments continue to emerge from ongoing research.
Promising new treatments continue to emerge from ongoing research. Negative pressure wound therapy uses controlled suction to promote healing. Growth factors and stem cell therapies show potential for accelerating tissue repair. Bioengineered skin substitutes provide a scaffold for new skin growth. Some patients benefit from pneumatic compression devices that intermittently squeeze the legs to improve circulation. Your healthcare team will work with you to develop a treatment plan tailored to your specific situation and needs.
Living With Chronic Venous Leg Ulcers
Managing life with chronic venous leg ulcers requires developing new daily routines, but most people adapt well and continue to lead active, fulfilling lives. Consistent wound care becomes part of your regular schedule, much like brushing your teeth. Many patients find it helpful to set up a designated area with all their supplies for easy daily dressing changes. Keeping a wound care diary can help you track healing progress and identify any concerning changes.
