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 ...

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.

Flow competition between hepatic arterial and portal venous flow during hypothermic machine perfusion preservation of porcine livers [PDF]
, 2012 Hypothermic machine perfusion (HMP) is regarded as a better preservation method for donor livers than cold storage. During HMP, livers are perfused through the inlet blood vessels, namely the hepatic artery (HA) and the portal vein (PO.

Blood mobilization from the liver of the anaesthetized dog [PDF]
, 1998 The abdominal circulation contains a high proportion of the total blood volume and this can change either passively in response to changes in vascular distending pressure or actively (termed a capacitance response) to changes in sympathetic nervous ...

Thalidomide ameliorates portal hypertension via nitric oxide synthase independent reduced systolic blood pressure [PDF]
, 2015 AIM: Portal hypertension is a common complication of liver cirrhosis and significantly increases mortality and morbidity. Previous reports have suggested that the compound thalidomide attenuates portal hypertension (PHT).
