Data are presented as the mean ± SD, with the range of values shown in parentheses. P < 0.05 was considered statistically significant. L-PV: Left portal vein; R-PV: Right portal vein; PV: Portal vein; PSV: Peak systolic velocity; RI: Resistance index; HA: Hepatic artery; LHA: Left hepatic artery; RHA: Right hepatic artery.
