title: Sinusoidal and postsinusoidal vascular systems in liver cirrhosis.
abstract: The morphology of the sinusoidal and postsinusoidal hepatic vein system in liver cirrhosis is shown by postmortem venography, microangiography and micropreparation. The normal angioarchitecture of the sinusoidal and hepatic vein system in lost in cirrhotic alteration of the liver. The hepatic veins are partly stenosed and displaced. Regenerate nodules, pseudolobules and extremely vascularized connective tissue septa, characterize the venous parenchymogram and microangiogram. The size of the regenerate nodules corresponds well to a granulomatous contrast of the parenchyma. The disordered intrahepatic angioarchitecture has clinical significance for hemodynamics and hepatic venous pressure measurement.
