title: Functional and non-functional liver blood flow in patients with liver cirrhosis measured by indocyanine green.
abstract: Indocyanine green administration was used in a group of ten patients with liver cirrhosis with portal hypertension to estimate hepatic extraction, liver blood flow and the degree of blood shunting. Extraction coefficients obtained by the hepatic catheterization were well correlated with the pharmacokinetic method. Values of the total liver blood flow measured by the classical method based on Fick's principle were always higher than those evaluated by the pharmacokinetic analysis estimating the functional liver blood flow only. Estimates of the degree of shunting varied between 32.0-78.9% of the total liver blood flow. A statistically significant correlation (r = 0.79) was found between the percentage of the functional fraction of the total liver blood flow and albuminemia. It is suggested that in liver cirrhosis with portal hypertension the reduction of the functional fraction of total liver blood flow is combined with partial impairment of hepatic cell metabolism in the remaining functional areas of the liver. In such a case neither the "intact" nor the "sick hepatocyte" hypotheses are appropriate in their strict sense for the interpretation of the findings.
