Peculiar characteristics of portal-hepatic hemodynamics of alcoholic cirrhosis

Table 1 Portal-hepatic hemodynamics in alcohol-related and viral cirrhosis

	Alcohol-related cirrhosis	Viral cirrhosis
Increase in intrahepatic resistance	Increase in sinusoidal and postsinusoidal resistance	Increase also in presinusoidal resistance
Portal pressure	Higher increase in sinusoidal pressure	Lower increase in sinusoidal pressure
Hepatic venous pressure gradient	Accurately reflects portal pressure	Less accurately reflects portal pressure
Portal perfusion of the liver per gram of tissue in end-stage liver disease	Higher reduction	Lower reduction
Reversal portal blood flow	More common	Rare
Patent paraumbilical vein	More common	Less common
Hyperdynamic circulation	More pronounced	Less pronounced
