FAQ Venous Ulcers

What is a venous ulcer?

Categories: Venous Ulcers

An ulcer (non-healing sore) in the skin refers to a place where the normal skin covering has been wiped away and the subcutaneous tissue under the skin shows through.  In the leg between the knee and the foot the most common cause of ulcers is leaking venous valves causing high pressure and abnormal circulation in the tiny vessels of the skin.  Ulcers represent a late stage of lower extremity vein disease (such as varicose veins or blood clots) when the abnormal circulation from longstanding reflux in the superficial or other veins causes the skin to become thickened and inflamed and it actually breaks down into an open sore.
