This study included data from 150 patients aged 18 to 65 years with cirrhosis of the liver with viral etiology. With METAVIR ultrasound elastography of the liver, the F4 fibrosis stage ranges from 12.5 kPa to 75 kPa. In the corresponding case, the following indicators of the development of complications of liver cirrhosis were obtained: 23.9 kPa – dilation of esophageal varicose veins, 25.2 kPa – hepatic encephalopathy, 25.2 kPa – ascites, 31.5 kPa – stages of decompensation B and C by Child - Pugh cirrhosis, 35.3 kPa – bleeding from enlarged esophageal varicose veins.
