The clinical value of color Doppler ultrasonography in measuring the hemodynamics of liver cirrhosis patients' portal and splenic veins.

Objective: To investigate the clinical value of color Doppler ultrasonography (CDUS) in measuring the hemodynamics of liver cirrhosis (LC) patients' portal and splenic veins.

Methods: The clinical data of 81 LC patients admitted to our hospital were collected retrospectively and classified into Group A, and the clinical data from 51 healthy volunteers were classified into Group B. All the patients were examined with CDUS, and the ultrasonography images were analyzed. The hemodynamic indices of the portal and splenic veins were compared, and the differences in the hemodynamic indices of the LC patients with varying degrees of esophageal varices and hepatic injuries were analyzed.

Results: Group A exhibited higher Q, D, Q, and D and lower V and V than Group B ( < 0.05). The Q and D of the patients with Grade B LC were higher than they were in the patients with Grade A LC and lower than they were in the patients with Grade C LC ( < 0.05). The V of the patients with Grade B LC was higher than it was in the patients with Grade C LC and lower than it was in the patients with Grade A LC ( < 0.05). The Q and D of the patients with Grade B LC were higher than they were in the patients with Grade A LC and lower than they were in the patients with Grade C LC ( < 0.05). The V of the patients with Grade B LC was higher than it was in the patients with Grade C LC and lower than it was in the patients with Grade A LC ( < 0.05). The patients with mild, moderate, and severe esophageal varices showed lower V and V and higher Q, D, Q, and D than the patients without esophageal varices ( < 0.05).

Conclusion: CDUS has certain clinical values in measuring the hemodynamics of LC patients' portal and splenic veins and can be used to predict the degrees of hepatic injuries and esophageal varices.
