This paper aims to investigate clinical value of intrahepatic and intra-stent hemodynamic changes after transjugular intrahepatic portosystemic shunt (TIPS), by using color Doppler ultrasound during the diagnosis of hepatic encephalopathy (HE) in the patients with hepatitis B cirrhosis. A retrospective analysis of the patients with hepatitis B cirrhotic portal hypertension, who underwent TIPS in The First Affiliated Hospital of Anhui Medical University from January 2018 to January 2021, was conducted. 22 patients who developed HE within 3 months after TIPS comprised the observation group (HE group), and 51 patients who did not develop HE were randomly selected as the control group (non-HE group). The porto systemic gradient (PSG), as well as intrahepatic and intra-stent hemodynamic changes of patients in both the HE group and the non-HE group after TIPS were investigated. The intra-stent blood flow, PSG difference, and PSG decrease percentage in the HE group were higher than those in the non-HE group, and the intra-stent flow had a weak positive correlation with PSG difference and with the PSG decrease percentage ( r  = 0.420, 0.258, respectively). The areas under the ROC curves of HE based on the PSG difference, the PSG decrease percentage, and the intra-stent flow were 0.762, 0.753, and 0.693, respectively. The more obvious decrease in PSG, the larger the intra-stent blood flow, and the larger the possibility of HE occurrence were observed. Routine ultrasound measurement of hemodynamic changes has certain clinical significance for predicting HE occurrence.
