METHOD OF NON-INVASIVE DIAGNOSTICS OF FIBROSIS IN CASE OF DIFFUSE LIVERE DISEASES

摘要

FIELD: medicine.;SUBSTANCE: invention relates to field of medicine, namely, to gastroenterology. For non-invasive diagnostics of fibrosis and cirrhosis in case of HBV and HCV infections complex ultrasonic examination of liver and spleen tissue is carried out. Additionally duplex scanning with colour Doppler mapping of porto-hepatic region vessels is performed and quantitative indices of hemodynamics of rate of blood flow in vessels, including splenic vein, are determined. Blood test is analysed and used to determine number of platelets, biochemical blood tests are performed, most significant for determination of disease degree indices of coagulogram are taken. After that, discriminant analysis of obtained characteristics and indices is carried out, and taking into account age and experimentally obtained coefficients, total value of two canonical discriminant functions F1 and F2 for HCV and HBV is calculated. Further, by obtained in empiric way territory map position of point for calculated by patient's concrete indices values F1 and F2 for cases of HCV-infection and HBV-infection is determined. Depending on point location on territory map case of mild fibrosis, severe fibrosis or liver cirrhosis is diagnosed.;EFFECT: method increases reliability of fibrosis and cirrhosis diagnostics in case of HBV and HCV infections.;10 dwg, 2 ex
