<unk>  is defined by the American<unk>  Forum as "a full-thickness defect of skin, most frequently in the ankle region, that fails to heal spontaneously and is sustained by chronic<unk>  disease, based on<unk>  duplex ultrasound testing."<unk> s are wounds that are thought to occur due to improper functioning of<unk>  valves, usually of the legs (hence leg ulcers). They are an important cause of chronic wounds, affecting 1% of the population.<unk> s develop mostly along the medial distal leg, and can be painful with negative effects on quality of life. Exercise, together with compression stockings, increases healing. The NICE guideline recommends that everyone with a<unk>  leg ulcer, even if healed, should be referred to a vascular specialist for<unk>  duplex ultrasound and assessment for endovenous surgery.
