RELATION OF PORTAL VENOUS PRESSURE TO OCCLUDED HEPATIC VENOUS PRESSURE

Archives of Surgery, 1954
THE OPERATIONS of portacaval anastomosis and hepatic artery ligation are predicated upon the fact that these procedures, by diverting blood from the liver, lower the pressure in the portal system and in the varices which have formed in that system. While it is easy to demonstrate at operation that there is an immediate fall in pressure in the portal ...

Portal venous pressure in biliary atresia

Journal of Pediatric Surgery, 2012
Biliary atresia (BA) is characterized by a variable degree of fibrosis within the liver, causing portal hypertension sometimes evident at the time of presentation.The aims of this study are to measure portal venous pressure (PVP) at time of Kasai portoenterostomy (KP) and to investigate the value of surrogate indices.At the time of KP and before any ...

Portal venous pressure and portasystemic shunting in experimental portal hypertension

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1989
The relationship between portal venous pressure and the degree of portasystemic shunting was studied in portal vein-ligated and cirrhotic rats anesthetized with halothane. One day after partial portal vein ligation there was a strong positive correlation (r = 0.80, n = 7) between portal pressure and shunting of mesenteric venous blood as measured by ...

Captopril reduces portal pressure effectively in portal hypertensive patients with low portal venous velocity

Journal of Gastroenterology, 2003
The effect of an angiotensin II blockade in lowering the portal pressure in patients with liver cirrhosis and portal hypertension is controversial. This prospective study was undertaken to evaluate the portal hypotensive effect of captopril compared to that of propranolol, and to determine the factors that contribute to a successful reduction in the ...

Passive autoregulation of portal venous pressure: distensible hepatic resistance

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1992
Hepatic 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 portal venous pressure in organic heart disease

American Heart Journal, 1954
Abstract 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 ...

Portal venous pressure changes after sequential clinical islet transplantation

Transplantation, 2002
Sequential pancreatic islet transplantation via the portal vein has led to insulin independence in patients with type 1 diabetes. Complications associated with the injection of islets into the portal vein have been reported; therefore, in this study we sought to further characterize changes in portal venous pressure associated with islet infusion.Pre ...

Portal Venous Pressure in Adult Living Donor Liver Transplantation

Transplantation Proceedings, 2014
The relationship between portal pressure and small-for-size syndrome (SFSS) is unsettled. The purpose of this study was to evaluate the role of portal pressure in predicting SFSS.Thirty-four patients with end-stage liver disease who received adult-to-adult living-donor liver transplantation (ALDLT) were included.
