Venous ulcers (venous insufficiency ulceration, stasis ulcers, stasis dermatitis, varicose ulcers, or ulcus cruris) are wounds that are thought to occur due to improper functioning of venous valves, usually of the legs (hence leg ulcers). They are the major occurrence of chronic wounds, occurring in 70% to 90% of leg ulcer cases. Venous ulcers develop mostly along the medial distal leg, and can be very painful. Edema and fibrinous exudate leads to fibrosis of subcutaneous tissues with localized pigment loss and dilation of capillary loops. This is called atrophic blanche. This can occur around ankles and gives an appearance of inverted champagne bottle to legs. Large ulcers may encircle the leg. Lymphedema results from obliteration of superficial lymphatics. There is hypertrophy of overlying epidermis giving polypoid appearance, known as lipodermatosclerosis

The health care provider will look for signs of infection, such as:
• Redness, increased warmth, or swelling around the wound
• Extra drainage
• Fever or chills
• Increased pain
HOW IS VENOUS ULCER TREATED?

1. Skin Grafting and artificial skin
3. Foam Sclerotherapy
