Doppler assessment of children with liver cirrhosis and portal hypertension in comparison with a healthy control group: An analytical cross?sectional study
mean velocities were 15.03 ± 7.3 cm/s in cirrhotics, 16.47 ± 6.4 cm/s in controls (P = 0.51), 11.6 ± 4.7 cm/s in patients with varices, and 17.9 ± 7.3 cm/s in patients without varices (P = 0.015). Mean diameters of caudate lobe, portal vein, and splenic vein, as well as the mean values of liver and spleen span, were signifcantly higher in cirrhotic children. Te frequency of ?ow reversal (hepatofugal ?ow) was not detected signifcantly di?erent in cirrhotics. Peak systolic velocity, end diastolic velocity, pulsatility index, and resistive index for hepatic artery as well as liver vascular index were not signifcantly di?erent in cirrhotics in comparison with controls.
Conclusions: Alterations in Doppler parameters of portal vein including diameter and velocity may be the helpful indicators of liver cirrhosis and esophageal varices in children, respectively. Parameters of hepatic artery may not di?erentiate children with liver cirrhosis.
