Portal hypertension leading to gastric polyposis has rarely been reported. More common gastric manifestations of portal hypertension are portal hypertensive gastropathy and gastric antral vascular ectasia (GAVE). We report a case of a patient in whom portal hypertension manifested as bleeding gastric polyps leading to transfusion-dependent iron deficiency anemia.

BACKGROUND Portal vein thrombosis was considered a contraindication for liver transplantation in the past because of the high morbidity and mortality rates. Many advances made the results better. AIM Review the advances and surgical strategies for liver transplantation in presence of portal vein thrombosis. METHOD Survey of publications in Medline, Scielo and Lilacs databases. Headings cros...

Patient portal adoption has rapidly increased, and portal usage has been associated with patients' sociodemographics, health literacy, and education. Research on patient portals has primarily focused on the outpatient setting. We explored whether health literacy and education were associated with portal usage in an inpatient population. Among 60,159 admissions in 2012-2013, 23.3% of patients re...

Portal biliopathy (PB) is a rare disorder, which mostly presents as sub-clinically. It occurs most commonly due to idiopathic extrahepatic portal vein obstruction. We present three cases having features of portal biliopathy secondary to portal hypertension. Our first case did not have a prior history of chronic liver disease while next two patients had previous history of chronic liver disease ...

The intraoperative measurement of the afferent circulation of the liver, namely the hepatic artery flow and portal venous flow was carried out upon 14 anesthetized patients having carcinoma in the splanchnic area, mainly in the head of the pancreas by means of transit time ultrasonic volume flowmeter. The hepatic artery flow, portal venous flow and total hepatic flow were 0.377 +/- 0.10; 0.614 ...

Tailed bacteriophages and herpesviruses assemble infectious particles via an empty precursor capsid (or 'procapsid') built by multiple copies of coat and scaffolding protein and by one dodecameric portal protein. Genome packaging triggers rearrangement of the coat protein and release of scaffolding protein, resulting in dramatic procapsid lattice expansion. Here, we provide structural evidence ...

Splanchnic organ blood flow and cardiac output were measured by the microsphere method in fasted rats with prehepatic portal hypertension due to portal vein stenosis, in rats with intrahepatic portal hypertension due to bile duct ligation, and in unoperated normal rats. Portal venous pressure was higher in both groups of portal hypertensive rats than in normal rats. Cardiac output was significa...

1. Portal hypertension and hyperdynamic circulation have been postulated to play a role in the pathogenesis of portal hypertensive gastropathy. Administration of octreotide to portal hypertensive rats has been shown to reduce portal pressure and ameliorate hyperdynamic circulation. 2. This study investigated the effects of chronic administration of octreotide on systemic and portal haemodynamic...

A case of appendicitis which resulted in portal pyaemia, hepatic and splenic abscesses, presumed portal vein thrombosis and subsequent portal hypertension is described. It confirms the merit of ultrasonic imaging in monitoring abscess resolution but questions the ability of the technique to recognise acute suppurative portal endophlebitis.

1 The hepatic portal vein of the anesthetized dog was cannulated and perfused with blood derived from the cannulated superior mesenteric vein. 2 The portal vein was perfused at constant flow, the hepatic portal venous pressure being monitored continuously together with the inferior vena caval pressure. From these measurements, the hepatic portal venous vascular resistance was calculated. 3 Nora...
