Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves , usually of the legs hence leg ulcers. Exercise together with compression stocking increases healing. The exact cause of venous ulcers is not certain, but they are thought to arise when venous valves that exist to prevent backflow of blood do not function properly, causing the pressure in veins to increase. When venous hypertension exists, arteries no longer have significantly higher pressure than veins, and blood is not pumped as effectively into or out of the area. Venous hypertension may also stretch veins and allow blood proteins to leak into the extravascular space , isolating extracellular matrix ECM molecules and growth factors , preventing them from helping to heal the wound. It is in the crus that the classic venous stasis ulcer occurs.

Venous ulcers open sores can occur when the veins in your legs do not push blood back up to your heart as well as they should. Blood backs up in the veins, building up pressure. If not treated, increased pressure and excess fluid in the affected area can cause an open sore to form. The cause of venous ulcers is high pressure in the veins of the lower leg. The veins have one-way valves that keep blood flowing up toward your heart.
