VENOUS STASIS ULCER
Venous stasis ulcers commonly occur in the legs due to venous insufficiency or poor venous blood drainage. Veins of the legs have valves in then which ensures a proper unidirectional flow of blood towards heart. In venous stasis, these valves are damaged, thus the venous blood accumulates in the legs instead of being pumped upwards. A prolonged pooling of blood in the leg leads to increased pressure in the affected area thus causing a break in the skin and causing ulcers. The causes for venous stasis could be smoking, occupations requiring prolonged hours of standing, obesity or deep vein thrombosis.
