Venous Ulcers
About Venous Ulcers
Venous ulcers are open sores or wounds that develop on the skin of the legs or feet due to the accumulation of blood in the veins.
Venous ulcers typically appear as shallow, irregularly shaped wounds that are slow to heal and may be surrounded by red or discolored skin. They can be painful, itchy, and may discharge fluid or pus. Risk factors for venous ulcers include obesity, a history of deep vein thrombosis, prolonged standing or sitting, and age.

What Causes Venous Ulcers?
They are often a result of chronic venous insufficiency, a condition in which the veins in the legs are unable to properly transport blood back to the heart. This leads to increased pressure in the veins, which can cause blood to leak into the surrounding tissues and result in the formation of an ulcer.
Other Causes: Prior Deep Vein Thrombosis
Prior deep vein thrombosis (DVT) can cause leg swelling, particularly if the DVT damaged the valves in the veins or caused scarring. When the blood flow in the veins is disrupted by a DVT, it can lead to increased pressure in the veins and cause fluid to accumulate in the affected leg, resulting in swelling. This swelling may also be accompanied by pain, warmth, and redness in the affected area. It’s important to seek medical attention if you experience any of these symptoms after a prior DVT, as they may indicate the development of another blood clot or other complications related to the previous DVT.
Treatment Options
Treatment for venous ulcers typically involves addressing the underlying cause of the condition, such as improving circulation in the affected area, managing any infections that may be present, and applying dressings or compression stockings to promote healing. In some cases, surgery or other procedures may be necessary to correct the underlying venous insufficiency.
