Venous Leg Ulcer
A venous leg ulcer is the erosion of the skin (wound) that develops as a result of chronic venous insufficiency and venous hypertension. This is usually caused by the improper functioning of venous valves in the legs. VLU usually develop in the lower leg between the ankle and mid-calf. VLUs are slow to heal and/or keep returning, can be painful, and require treatment or they will get worse.
They often referred to as “Active / Oozing Wounds”, which describes drainage or exudatation of wound fluid. Exudate is often associated with inflammation and results from leakage from capillaries in the affected area. The oozing can be clear to slightly yellowish (serous) fluid or it can be combined with blood (serosanguinous). If there is wound infection the wound fluid is greater in volume, can be combined with bacterial debris (purulent) and may be foul-smelling.
