title: Correlation between liver morphology and haemodynamics in alcoholic liver disease.
abstract: In 32 alcoholic patients the degree of hepatic architectural destruction was graded (preserved architecture, nodules alternating with preserved architecture, totally destroyed architecture) and related to portal pressure. A significant positive correlation was found between degree of architectural destruction and wedged-to-free hepatic vein pressure (W-FHVP) (p less than 0.001). The degree of necrosis, fatty change and inflammation showed no correlation with portal pressure, whereas a significant positive correlation was found between the occurrence of Mallory bodies and W-FHVP (p less than 0.01) and between degree of fibrosis and W-FHVP (p less than 0.001). In 22 of the patients, hepatic blood flow (HBF) was measured and in these patients hepatic resistance was calculated (W-FHVP/HBF). A significant positive correlation was found between fibrosis and hepatic resistance (p less than 0.01). Further, hepatic architectural destruction (p less than 0.01) was positively correlated to hepatic resistance. Necrosis, fatty change, occurrence of Mallory bodies or inflammation showed no significant correlation with hepatic resistance. Mean hepatocyte volume was calculated in 29 patients, but no correlation was found with haemodynamic variables. The present data substantiate the concept that established portal hypertension in alcoholic liver disease is mainly accomplished by a derangement in hepatic architecture, whereas parenchymal changes, including hepatocyte size, are of less importance.
