Presinusoidal Obstructions,Prehepatic obstructions are the most common form of presinusoidal portal hypertension, usually resulting from portal vein or splenic vein thrombosis. Unlike postsinusoidal obstructions, a normally low pressure portal venous bed is preserved beyond the obstacle, which is responsible for some specific hemodynamic changes.

,Normal Hepatic Circulation — Anatomy and Physiology,by the blood sinusoids radiating from the periphery of the lobule towards a central vein. The sinusoids are supplied with blood by portal venules and hepatic artery branches running in the interlobular spaces or portal tracts at the periphery of the lobules.

Diffuse Post-Sinusoidal Obstructions,arly recognized. In case of presinusoidal obstruction hepatic venography and wedged hepatic vein pressure are normal. On the other hand, an increased wedged hepatic vein pressure with heterogenous sinusoidal filling, narrowing and distortion of small hepatic venules on hepatic venography are typical of a post-sinusoidal obstacle.
