Portal Venous Pressure Variation during Hepatectomy: A Prospective Study
Acta Médica Portuguesa, 2019 Introduction: Excessive portal venous pressure in the liver remnant is an independent factor in the occurrence of posthepatectomy liver failure and small-for-size syndrome. The baseline portal pressure prior to hepatectomy was not considered previously.

Imaging of Portal Gastroduodenopathy
Journal of Gastrointestinal and Abdominal Radiology, 2021 Portal hypertension is characterized by elevated pressure in portal venous system due to portal resistance due to various causes. The etiologies are either pre-hepatic, hepatic, or post-hepatic.

Esophageal Varices Bleeding in Portal Hypertension Due to Portal Vein and Splenic Vein Obstruction [PDF]
, 2002 Based on its relation to the liver sinusoid, increased pressure of portal vein can occur at three levels: presinusoid, sinusoid ,and postsinusoid. Obstruction of the presinusoid veins can be caused by extra- hepatic condition such as venous thrombosis ...

Ammonia produces pathological changes in human hepatic stellate cells and is a target for therapy of portal hypertension [PDF]
, 2016 BACKGROUND AND AIMS: Hepatic stellate cells (HSCs) are vital to hepatocellular function and the liver response to injury. They share a phenotypic homology with astrocytes that are central in the pathogenesis of hepatic encephalopathy, a condition in ...
