Early development of cavernomatous vasculatures in portal venous thrombosis: morphometric kinetics in rabbit model.

We tried to establish an animal model of portal venous thrombosis in order to analyze the ensuing pathological changes of the liver. An emulsion with Escherichia coli endotoxin and Lipiodol-Ultra-Fluide was injected into the portal vein of the left anterior lobe of the rabbit liver. The target lobe and portal vein were time-sequentially examined.
