Venous Stasis Ulcer
(Hypostatic ulcer; Stasis ulcer)
Ve-nus Sta-sis Ull-sir
by Cynthia M. Johnson, MA
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 series 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.
