PERIODIC CHANGES IN THE LIVER VOLUME AND CHANGES IN THE PORTAL VENOUS PRESSURE
1) We have made clear the periodic contractions in the volume of such organs, as the spleen, intestine, kidney, etc., and the periodic changes in the venous and arterial blood pressures, resulting from above phenomena (8, 9, 10). However, now we were able to observe the volume changes of periods ranging from 15 to 38seconds in the liver, brought about ...

levels were measured 4 times during the first week (24,48,72,120,168 hours) and twice a week in the remaining 3 weeks (National Genetics Institute, Culver City, CA). Clearance of HCV-RNA was considered as primary virological response. Baseline HCV-RNA levels ranged from 100 to 35.000.000 eq/ml (mean 4.513.689 eq/ml). Genotypes: la 1 (5.8%), lb 13 (76.5%

Portal Venous–Esophageal Luminal Pressure Gradient in Cirrhosis [PDF]
The portal venous–esophageal luminal pressure gradient may be more important than the absolute portal venous pressure in explaining hemorrhages caused by esophageal varices. A continuous recording of portal venous pressure and the esophageal luminal pressure enabled the authors to study the gradient between these pressures in ...

Comparison of artificial neural network-predicted PPG and HVPG with measured PPG in decompensated cirrhosis patients [PDF]
Portal hypertension (PHT) is pivotal in managing decompensated cirrhosis. In clinical practice, hepatic venous collaterals are frequently present, often leading to failure or reduced accuracy of hepatic venous pressure gradient (HVPG) measurements ...

Background/Aims Transient elastography (TE) has been proposed as a promising noninvasive alternative to hepatic venous pressure gradient (HVPG) for detecting portal hypertension (PH). However, previous studies have yielded conflicting results.

Effects of Octapressin on Portal Venous Pressure
octapressinの門脈圧下降作用を追求する目的で,2例の肝硬変症例および2例の慢性肝炎症例に,同剤の微量緩速点滴静注を行なった.同剤の注入開始後1~2分で閉塞肝静脈圧の下降が始まり,10分以内に減少率14~45%の下降を示した.同剤の注入量は0.4~1.8単位であったが,下降率は注入量に比例せず,むしろ,投与前の閉塞肝静脈圧の高い症例ほど,大きい減少率を示した.末梢動脈血圧は,13~41%上昇し,脈拍数は28~35%減少した.閉塞肝静脈圧は,同剤注入中止後約30分で前値に復した.副作用として,軽度の腹痛,顔面蒼白,尿意を認めたが,格別の処置なく消失した.

The Portal Venous Pressure in Man
Mall1, 2 appears to have been the first to record the portal venous pressure in animals under experimental conditions. The later determinations by Burton-Opitz3, 4, 5 were shortly followed by Tiger-stedt's6 records. These observers used the technically difficult T-cannulation of the portal vein, although this itself probably interfered with the normal ...

Effect of peritoneo-venous shunt on portal pressure. [PDF]
The cause of variceal bleed after a peritoneo-venous shunt is not known. Portal haemodynamic consequences of a peritoneo-venous shunt are poorly understood. The most critical period after a peritoneo-venous shunt is the early postoperative period when rapid mobilisation of peritoneal fluid occurs.

Combined hepatic and umbilicoportal catheterization was performed in 43 compensated cirrhotic patients. The umbilicoportal catheter was positioned in the portal vein (41 patients) or the left branch of the portal vein (2 patients). Wedged hepatic venous pressure was equal to free portal venous pressure in 17 patients.
