Abstract: Objective To explore the evaluation value of shear wave elastography (SWE) and portal venous hemodynamic parameters for the severity of liver fibrosis. Methods Sixty-six patients with liver cirrhosis admitted between October 2024 and August 2025 were enrolled in this study. Among them, 27 cases were of Child-Pugh grade A, 21 cases of grade B, and 18 cases of grade C. Additionally, 24 healthy individuals who underwent physical examinations at our hospital were selected as the control group. The average liver SWE (Emean) was measured using SWE technology, and the portal vein diameter (PVD) and resting portal vein velocity (PVV) were detected using ultrasound CDFI technology. By comparing PVD, PVV, and Emean parameters, the correlation between Emean, PVD, PVV, and Child-Pugh score in liver cirrhosis were evaluated, and the application value of these parameters in assessing the degree of liver fibrosis were analyzed. Results The Emean values of the Child-Pugh grade A. B and C groups of patients were (9.90 ± 1.64) kPa, (16.84 ± 3.2) kPa, and (19.62 ± 6.89) kPa, respectively. The PVD values were (11.96 ± 3.6) mm, (13.37 ± 1.2) mm, and (13.90 ± 2.81) mm, respectively. The PVV values were (14.15 ± 2.12) cm/s, (12.25 ± 1.75) cm/s, and (11.07 ± 1.49) cm/s, respectively. There were statistically significant differences in liver Emean, PVV, and PVD between the patients′ groups and the control group (P<0.05), and there were statistically significant differences in liver Emean, PVD, and PVV between patients with different grades of liver function (P<0.05) (F value=29.988, 4.371, 14.078, respectively). PVD, PVV, and liver Emean in patients with cirrhosis are correlated with Child-Pugh grading (correlation coefficients rates=0.269, -0.701, 0.741, respectively). Conclusion Liver SWE and portal vein hemodynamics are closely related to the degree of liver fibrosis in patients with chronic liver diseases. Color doppler ultrasound combined with shear wave elastic imaging technology has a good evaluation efficacy for the severity of liver cirrhosis.
