Chronic venous disease and venous leg ulcers: An evidence-based update

Abstract

Chronic venous disease (CVD) is a complex chronic vascular condition with multifaceted primary and secondary etiologies leading to structural and functional changes in veins and valves and blood flow of the lower legs. As a consequence, a spectrum of clinical manifestations arise, ranging from symptoms of mild leg heaviness and achiness to debilitating pain, and signs of skin changes, such as eczema and hemosiderosis, to nonhealing, heavily draining venous leg ulcers (VLUs). Triggers such as trauma to the skin are responsible for a large majority of VLU recurrences. Diagnostic testing for venous reflux includes ultrasound imaging; unfortunately, there are no diagnostic tests to predict VLUs. The hallmark of treatment of both CVD and VLUs is compression. Leg elevation, exercise, and wound management with dressings and advanced healing technologies that provide an environment conducive to healing should focus on reducing pain, necrotic debris, drainage, and odor, as well as preventing infection. VLUs that become chronic without evidence of healing over a 4-week period respond best to multidisciplinary wound experts within a framework of patient-centered care. Nurses are in key positions to provide early recognition of the signs and symptoms as well as initiate prompt diagnostic and promote early treatment to offset the progression of the disease and improve quality of life.
