Determinación del Valor Predictivo para el Engrosamiento de Uñas por Insuficiencia Venosa Profunda con la Prueba de Koh y su Relación con Pacientes Sintomáticos

Abstract

Peripheral venous insufficiency (IVP) can be assessed using severity scores. However, individual factors that can lead to this condition have not been well described, and one of them is the secondary nail dystrophy with IVP. The aim of this study was to analyze the clinical utility of predictive value for thickening nail deep venous insufficiency with KOH test and its relationship with symptomatic patients. 60 patients, 23.3% were men, the presence of fungi was 42.3% and patients showed some degree of IVP just 11 confirmed that the dystrophy was because of onychomycosis was 36.7% , there was association between dystrophy and the presence of IVP was found significant (p = 0.045). KOH test has a specificity of 100% for onychomycosis, the probability that it is presented dystrophy is consequently of venous insufficiency is moderately high (55.8%), but keep the fact that test negative, (positive KOH) does not rule IVP dystrophy, because we found a negative predictive value of 57.6% (higher than the positive predictive value); so their use for secondary screening dystrophy IVP is not recommended.
