BACKGROUND After portal vein ligation of 1 side of the liver, the other side regenerates at a slow rate. This slow growth may be accelerated to rapid growth by adding a transection between the 2 sides, i.e., performing portal vein ligation and parenchymal transection. We found that in patients undergoing portal vein ligation and parenchymal transection, portal vein hyperflow in the regenerating...
Portal hypertension, defined as an increase in pressure within the portal vein, is a detrimental complication in liver diseases. The increased intrahepatic resistance as a consequence of cirrhosis is the primary cause of portal hypertension (Figure 1). Once it is developed, portal hypertension influences extrahepatic vascular beds in the splanchnic and systemic circulation. Two major consequenc...
This paper describes the machine translation (MT) site PorTAl developed aiming at integrating useful tools and resources for MT and the multilingual processing. Currently under development, the PorTAl will provide tools and resources for Brazilian Portuguese, English and Spanish (initially). In a near future we believe that the PorTAl will stimulate a progress in multilingual applications, part...
Identifying the effects of patient portal use on patient engagement with the healthcare delivery system is an active research area. This study aims to understand the link between overall patient portal use (portal activity) and overall health system utilization (encounters) through the analyses of data logs from the patient portal and Electronic Health Record (EHR) system in a large multi-speci...
OBJECTIVE Only a limited proportion of patients needing pharmacological control of portal hypertension are hemodynamic responders to propranolol. Here we analyzed the effects of zolmitriptan on portal pressure and its potential interaction with propranolol. METHODS ZOLMITRIPTAN, PROPRANOLOL OR BOTH WERE TESTED IN TWO RAT MODELS OF PORTAL HYPERTENSION: common bile duct ligation (CBDL) and CCl4...
BACKGROUND The role of surgical resection for hepatocellular carcinoma with tumor thrombi involving the major portal vein is controversial because of a high operative risk and poor prognosis. Previously, a resection was performed only when the tumor thrombi were limited to the first branch of the portal vein without extension to the portal bifurcation. HYPOTHESIS Concomitant liver and portal ...
