Aim of the study: Portal vein congestion index has shown promise in detecting early portal venous hemodynamic changes in chronic liver disease. The aim of this study was to compare the portal vein congestion index of adult patients with chronic liver disease to that of healthy controls, and to evaluate the differences in portal vein congestion index, if any, between the common etiologies of chronic liver disease (chronic viral hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease). Method and materials: Eighty participants with chronic liver disease and 80 healthy controls had their sociodemographic variables, anthropometric indices, liver size/echotexture, spleen size, presence of ascites, and portal vein parameters (diameter, cross-sectional area, velocity, and congestion index) evaluated. P ≤0.05 was considered statistically significant. Results: There were 48 (60%) males and 32 (40%) females in the control group, while 56 (70%) males and 24 (30%) females were included in the chronic liver disease group (p = 0.185). Of the eighty people with chronic liver disease, 57 (71.2%) were diagnosed with alcoholic liver disease, while 23 (28.8%) were diagnosed with chronic viral hepatitis. There were no cases of non-alcoholic fatty liver disease during the study period. The mean liver spans of the control and chronic liver disease groups were 13.45 ± 0.85 cm and 16.50 ± 4.96 cm, respectively. All the controls had normal hepatic parenchymal echogenicity, while 45 (56.3%) subjects with chronic liver disease (36 alcoholic liver disease and 9 chronic viral hepatitis) had increased hepatic echogenicity. The mean values of the portal vein congestion index for the control and chronic liver disease groups were 0.0775 ± 0.02 cm/sec and 0.1037 ± 0.03 cm/sec, respectively (p <0.0001). Conclusion: The chronic liver disease group showed a significantly higher mean portal vein congestion index than the control group.
