Hepatic venous pressure gradient: clinical use in chronic liver disease [PDF]
Clinical and Molecular Hepatology, 2014 Portal hypertension is a severe consequence of chronic liver diseases and is responsible for the main clinical complications of liver cirrhosis. Hepatic venous pressure gradient (HVPG) measurement is the best available method to evaluate the presence and

Portal Pressure Responses to Catecholamines
Experimental Biology and Medicine, 1972 SummaryThe effects of norepinephrine and epinephrine (0.1 and 1.0 μg kg-1) upon portal, arterial, and central venous pressures were measured during drug injections into the portal vein, vena cava, and hepatic artery of anesthetized dogs. The small dose of norepinephrine and epinephrine evoked maximal increases in portal pressure when injected into the ...

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 Approach to Portal Hypertension
Journal of Gastrointestinal and Abdominal Radiology, 2023 Increase in portal venous pressure (termed portal hypertension) is seen in a variety of liver diseases. Imaging tests are useful to detect portal hypertension and identify its cause.

Effect of Portal Venous Blood Flow Diversion on Portal Pressure [PDF]
Journal of Clinical Investigation, 1980 To anticipate the hepatic vascular response to portacaval anastomosis, we studied portal pressure during diversion of portal blood through a temporary extracorporeal umbilical vein to saphenous vein shunt. The relationship of portal pressure to shunted flow was approximately linear.

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.

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 ...
