Background: Sonography is a useful tool in the study of the hepatic haemodynamic alterations that occur in chronic hepatitis B virus (HBV) infection using the portal vein congestion index (PVCI). The study was aimed at sonographically assessing the portal vein congestion index in adults with chronic HBV infection and at comparing the same with apparently healthy adults. Methods: This was a comparative, cross-sectional study carried out amongst 124 subjects (62 chronic HBV patients and 62 uninfected, apparently healthy individuals). The participants underwent routine grey scale evaluation of the liver, Doppler ultrasonographic evaluation of the portal vein and the ratio of the portal vein cross-sectional area in centimetre square to the portal vein velocity in centimetre per second. Results: In healthy controls, the mean PVCI was 0.048±0.010 cm, while the mean PVCI in chronic HBV patients was 0.077±0.028 cm (P < 0.001). The mean of duration of illness was 3.63 years with a range of 0.5–15. There was a weak negative correlation between PVCI and duration of illness (r = −0.130, P = 0.313). Conclusions: The PVCI was significantly higher in chronic HBV patients compared to healthy subjects. However, there was a weak correlation between PVCI and duration of illness in patients with chronic HBV.
