A venous stasis ulcer is wound on the skin. It is due to a pooling of blood in the veins. These ulcers happen most often on the legs.
If left untreated, the ulcers can lead infection and other serious problems.
Venous stasis ulcers are caused by a problem in veins. Valves in the veins normally move blood in the right direction. When the valves fail, blood flows backward and pools in the veins. This pushes blood cells and fluid into nearby tissue. The leaked fluids irritate the tissue. Over time, inflammation causes ulcers to form.
Venous stasis ulcers are more common in women and people over 65 years old. Other things that raise the risk are:
