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.
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.
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]
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.
The treatments to prevent the formation of blood clots are balanced against the risk of bleeding. [5] One of the goals of blood clot prevention is to limit venous stasis as this is a significant risk factor for forming blood clots in the deep veins of the legs. [6] Venous stasis can occur during the long periods of not moving.
An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is ...
For venous stasis ulcers, the paste-impregnated wrap is covered by an elastic layer, generally an elastic wrap ("ACE" bandage) or self-adherent elastic bandage such as Coban; this is referred to as a 2-layer compression bandage. An alternative treatment is a 4-layer, graduated compression wrap (Pro-Fore is an example).
Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds [2] and mostly affect the elderly. They are thought to be due to venous hypertension caused by improper function of valves that exist in the veins to prevent blood from flowing backward.
