    Abstract:
    We have correlated flow abnormalities in the hepatic vasculature with histological findings in the liver to determine the accuracy of Doppler ultrasound in the diagnosis of liver cirrhosis in children. Eighteen children admitted for evaluation of unknown liver disease were examined prospectively and blindly with Doppler ultrasound prior to liver biopsy. Biopsy specimens showed established cirrhosis in 9 of 18, early cirrhosis in 5 of 18, and no cirrhosis in 4 of 18 children. Doppler studies were also performed on 20 control subjects. The portal vein velocity was decreased (p < 0.0005) and the arterio-portal velocity ratio was increased (p < 0.0005) in the established cirrhosis cohort relative to the controls. For the criteria of the established cirrhosis cohort, the sensitivities of the loss of the reverse flow component in the hepatic veins, the arterio-portal velocity ratio being greater than 3.0, the portal vein velocity being less than 20 cm/s, and the existence of focal flow acceleration in the hepatic veins were 100%, 78%, 67%, and 44%, respectively. The specificity of all these criteria was 100%. The indicators were not useful in the diagnosis of early cirrhosis.
