QUALITY OF LIFE MEASURING INSTRUMENTS IN CHRONIC VENOUS DISEASE What’s the best option? • Class 05 • Introdução à Medicina II - 2010/2011
Chronic Venous Disease • Definition “Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.” Source: http://www.ncbi.nlm.nih.gov/mesh
Clinical signs (CEAP) C0 No visible or touchable symptoms C1 Reticular veins C2 Varicose veins C6 Skin ulceration C5 Healed ulcers C3 Edema C4 Trophic skin alterations
QualityofLife “It is a generic concept reflecting concern with the modification and enhancement of life attributes, e.g., physical, political, moral and social environment; the overall condition of a human life.” Source: http://www.ncbi.nlm.nih.gov/mesh?term=life%20quality
