Leg wounds are a common and difficult problem. Having a chronic leg wound can significantly affect quality of life. Of all leg wounds, 70% are from vein problems.
The vein problems may be from more superficial veins like varicose veins or can occur after a deep vein thrombosis. This is often associated with leg swelling and skin damage. This is known as Post Thrombotic Syndrome.
Some are from other vascular causes such as blocked arteries, with resultant decreased oxygenation of the tissue. In addition, there are other causes of ulceration such as trauma, infection, skin cancers, diabetes and microvascular disease.
Nutrition plays a vital role in wound healing as does normal lymphatic function. Problems with these may delay wound healing.
