| Risk Factors
Venous stasis is a pooling of blood in the veins. A venous stasis ulcer is a wound on the surface of the skin caused by pooled blood. These ulcers occur most often on the legs.
Veins have a serious of valves that help the blood move in the right direction. When these valves fail to work properly, blood can move backward and pool in the veins. The pooled blood pushes fluid and blood cells out of the veins and into nearby tissue. The leaked fluids irritate the tissue and cause inflammation. Over time, the inflammation can breakdown tissue and lead to ulcers.
Venous stasis ulcers are more common in women than in men. It is also more common in older adults.
Venous stasis increases your risk for this ulcer. Factors that may increase your risk of venous stasis include:
- Diseases or conditions of the veins, including:
- Trauma to leg or veins
- Family history of chronic venous disease
- Heart failure
- Injection drug use
Smoking is harmful to blood vessels and may play a role in venous stasis.

Venous stasis ulcers:
- May be painful and itchy
- Will take at least 4 weeks to heal
- May have discolored, darkened, and scaly skin around the edges
- May have foul-smelling discharge from the wound if an infection is present
Venous stasis may also cause:
- Swollen ankles, legs, and/or veins
- Flaky, scaly, and itchy skin on the legs
- Pain and/or heaviness in the legs
You will be asked about your symptoms and medical history. A physical exam will be done. The diagnosis can often be done based on history and appearance alone.
Ultrasound or other imaging test may be done to evaluate blood flow.
Talk with your doctor about the best treatment plan for you. The ulcer will need some time to heal. Special dressings are usually needed to help healing.
Supportive care will help tissue heal as quickly as possible and decrease the risk of infection. Options include:
Decreasing venous stasis and moving excess fluid away from the area to further decrease irritation and help healing. Steps may include:
- Wearing compression stockings as advised by your doctor
- Elevating the affected limb above the heart
- Exercises to help use muscle to pump fluid out of the area.
Certain medication will help promote blood flow. They may be oral medications or be applied directly to the skin. Options may include:
- Blood thinners
Other topical medication may be used to improve the health of the skin to promote healing.
Surgery may be needed to improve healing. Surgery may be done to:
- Remove dead or infected tissue
- Place healthy skin over the wound to help healing
- Treat cause of venous stasis
Venous stasis ulcers often recur. Prevention may include managing venous stasis or factors that worsen stasis, such as obesity.
