%X Introduction: Chronic venous insufficiency (CVI) is a dysfunction of the venous systemof the inferior limbs, in which it is formed a venovenous short circuit with alteration inthe physiologic flow of the blood.Objective: To estimate the degree of diagnostic concordance between the dilation ofthe great saphenous vein and the presence of chronic venous insufficiency (CVI).Methods: Diagnostic concordance study, where were included all the patients that wentbetween the months of April and May 2011 to the service of radiology of the HospitalUniversitario del Caribe, Cartagena, Colombia to make itself a colour Doppler ultrasoundof inferior limbs because of suspicion of CIV. Data was saved and analyzed by meansof the statistical program EPI-INFO version 3.5.1. Statistical analysis was focused inthe estimation of the kappa concordance index, the diameter of the saphenous with thepresence of CVI. Moreover there were calculated the parameters of diagnostic validitylike sensibility, specificity, predictive values and probability quotient.Results: There were recruited 77 patients, 64 women and 13 men. Of the total ofpatients, 47 had ebb and of them, 41 had dilation of the great saphenous vein, for whatthe dilation of this vein per se has sensibility of 87.2% and specificity of 93,1% for thediagnosis of CVI with positive predictive value (PPV) of 95.3% and negative predictivevalue of 81.8%.Conclusion: There is good diagnostic concordance between the dilation of the greatsaphenous vein and the CVI.
