The portal venous pressure in organic heart disease
American Heart Journal, 1954Abstract Catheterization of the hepatic veins was performed in four cases of congestive cardiac failure and in thirteen patients with compensated organic heart disease in an attempt to evaluate the portal venous pressure. Portal hypertension was not present in any of the cases and the results would appear to show that the raised readings were due ...

In dogs anesthetized with pentobarbital, central vena caval pressure (CVP), portal venous pressure (PVP), and intrahepatic lobar venous pressure (proximal to the hepatic venous sphincters) were measured. The objective was to determine some characteristics of the intrahepatic vascular resistance sites (proximal and distal to the hepatic venous ...

Hepatic arterial and portal venous pressure-flow relationships in isolated, perfused liver.
American Journal of Physiology, 1962Blood pressure responses to alteration in blood flow were studied in the completely isolated, excised liver of the calf during perfusion of the hepatic artery or portal vein.

To clarify the effect of splenomegaly on portal hemodynamics in patients with portal hypertension and esophageal varices, manometric studies were carried out before and after splenectomy during an operation for esophageal varices. The 118 patients evaluated retrospectively had underlying liver cirrhosis (LC) (62), idiopathic portal hypertension (IPH ...

Living Donor Liver Transplantation and Management of Portal Venous Pressure
Transplantation Proceedings, 2006Small-for-size syndrome occurs in the presence of a reduced mass of liver that is insufficient to maintain normal liver function. It has been speculated that this dysfunction is principally associated with graft exposure to excessive portal perfusion. The aim of these cases was to evaluate the efficacy of octreotide, a splanchnic vasoconstrictor, and ...

BACKGROUND AND STUDY AIMS Changes in portal pressure during endoscopy have not been previously evaluated. The aims of this study were to assess the effect of esophagogastroduodenoscopy (EGD), colonoscopy, and endoscopic retrograde ...

Possible equilibration of portal venous and central venous pressures during circulatory arrest
American Journal of Physiology-Heart and Circulatory Physiology, 1993The mean circulatory filling pressure technique has been used to assess total body venous tone. It involves measuring central venous pressure (CVP) at 5-8 s following circulatory arrest. This study examines if CVP and portal venous pressure (PVP) equilibrate when circulation is stopped by inflating a balloon implanted in the right atrium.

Distensibility of hepatic venous resistance sites and consequences on portal pressure
American Journal of Physiology-Heart and Circulatory Physiology, 1988Hepatic venous resistance was measured in cats anesthetized with pentobarbital sodium during changes in hepatic blood flow and in inferior vena cava (IVC) pressure, in an attempt to explain the variable and partial transmission of pressure from IVC to portal vein.

Passive autoregulation of portal venous pressure: distensible hepatic resistance
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1992Hepatic resistance to portal blood flow is extremely low and both the pre- and postsinusoidal resistance sites are distensible. Both isolated in situ and in vivo vascular circuitry were used in cats to demonstrate the principle of distensible resistance as a mechanism for the observation that blood flow was able to be decreased from 50 to 20 ml.min-1 ...

The impact of endoscopic variceal ligation on the pressure of the portal venous system
Journal of Hepatology, 1996Endoscopic variceal ligation is a viable substitute for injection sclerotherapy. It is still not known how endoscopic variceal ligation may influence the portal venous system. To clarify this issue we investigated the impact of endoscopic variceal ligation on the pressure of the portal venous system.Twenty-nine patients with a history of esophageal ...
