A venous ulcer tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A venous ulcer is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.
Potential complications of venous stasis are: Venous ulcers; Blood clot formation in veins (venous thrombosis), that can occur in the deep veins of the legs (deep vein thrombosis, DVT) or in the superficial veins; Id reactions [1]
An Unna’s boot [1] (also Unna boot) is a special gauze (usually 4 inches wide and 10 yards long) bandage, which can be used for the treatment of venous stasis ulcers and other venous insufficiencies of the leg. It can also be used as a supportive bandage for sprains and strains of the foot, ankle and lower leg.
Venous ulcers are common and very difficult to treat. Chronic venous ulcers are painful and debilitating. Even with treatment, recurrences are common if venous hypertension persists. Nearly 60% develop phlebitis which often progresses to deep vein thrombosis in more than 50% of patients. The venous insufficiency can also lead to severe hemorrhage.
Maggots in medical packaging. Maggot therapy improves healing in chronic ulcers. [1] In diabetic foot ulcers there is tentative evidence of benefit. [3] A Cochrane review of methods for the debridement of venous leg ulcers found maggot therapy to be broadly as effective as most other methods, but the study also noted that the quality of data was poor.
Though early use focused on burns and surgical wounds, [1] wider use of wounds treated with TCOT have become more common in diabetic foot ulcers, venous stasis and decubitus ulcers (pressure sores). TCOT involves inserting a thin tube which delivers the oxygen above the wound bed of a cleaned wound.

Venous skin ulcers that may appear on the lower leg, above the calf or on the lower ankle usually cause achy and swollen legs. If these ulcers ...
[1] [2] [3] The use of this technique in wound management started in the 1990s and this technique is often recommended for treatment of a range of wounds including dehisced surgical wounds, closed surgical wounds, open abdominal wounds, open fractures, pressure injuries or pressure ulcers, diabetic foot ulcers, venous insufficiency ulcers, some ...
