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 Qpv, Dpv, Qsv, and Dsv and lower Vpv and Vsv than Group B (P < 0.05). The Qpv and Dpv 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 (P < 0.05). The Vpv 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 (P < 0.05). The Qsv and Dsv 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 (P < 0.05). The Vsv 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 (P < 0.05). The patients with mild, moderate, and severe esophageal varices showed lower Vpv and Vsv and higher Qpv, Dpv, Qsv, and Dsv than the patients without esophageal varices (P < 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.
