13. Superoxid dismutase activity in portal vein endothelium after partial liver resection
PURPOSE: To investigate superoxide dismutase (SOD) activity in the portal vein endothelium and malondialdehyde acid (MDA) production in liver tissue of rats submitted to 70% hepatectomy. METHODS:Twelve rats were distributed in two groups (hepatectomy and sham). Animals were sacrificed on post operative day 1 and portal vein, liver tissue and blood samples we

14. A modified microsurgical model for end-to-side selective portacaval shunt in the rat: intraoperative microcirculatory investigations
PURPOSE: To investigate the intraoperative microcirculatory changes of the affected organs (small bowel, liver and kidney) during the making of a modified selective portacaval (PC) shunt. METHODS: On ten anaesthetized Sprague-Dawley rats the selective end-to-side mesocaval anastomosis was performed, where only the rostral mesenteric vein is utilized and the

15. Doppler venoso fetal na insuficiência placentária: relação com o pH no nascimento / Fetal venous Doppler in pregnancies with placental dysfunction: correlation with pH at birth
OBJECTIVE: This study, conducted in high-risk pregnancies with placental insufficiency, aims to avaliate blood flow in the fetal left portal vein (LPV), umbilical vein (UV) and ductus venosus (DV), and establish which parameters are associated with acidemia at birth. METHOD: A prospective research involving 58 pregnant women, classified according to the pres

16. Indicadores laboratoriais e ultrassonográficos preditivos de varizes esofágicas em crianças e adolescentes com hepatopatia crônica e obstrução extra-hepática da veia porta / Laboratory and ultrasonographic predictors of esophageal varices in children and adolescents with chronic liver disease and extra-hepatic portal vein obstruction
Objetivo: Identificar preditores não invasivos de varizes esofágicas em crianças e adolescentes com hepatopatia crônica e obstrução extra-hepática da veia porta (OEHVP). Casuística e métodos: Estudo prospectivo que incluiu 53 crianças e adolescentes com hepatopatia crônica ou OEHVP, sem antecedente de hemorragia digestiva ou tratamento de varizes

17. Trombose de veia porta no transplante hepático
INTRODUÇÃO: A trombose de veia porta foi considerada contraindicação ao transplante de fígado no passado em razão da elevada morbi-mortalidade. Diversos avanços permitiram melhora dos resultados. OBJETIVO: Revisão dos avanços e das estratégias cirúrgicas utilizadas para realização do transplante de fígado na vigência de trombose de veia porta.

18. The diameter of the originating vein determines esophageal and gastric fundic varices in portal hypertension secondary to posthepatitic cirrhosis
OBJECTIVE: The aim of this study was to determine whether and how the diameter of the vein that gives rise to the inflowing vein of the esophageal and gastric fundic varices secondary to posthepatitic cirrhosis, as measured with multidetector-row computed tomography, could predict the varices and their patterns. METHODS: A total of 106 patients with posthepa

19. Avaliação da da reprodutibilidade da mobilidade diafragmática pelo método ultrassonográfico indireto / Reproducibility assessment of the diaphragmatic mobility by indirect ultrasonographic method
Objetive: Assessing the reproducibility of the ultrasonographic measurement of craniocaudal displacement of the left branches of the portal vein as a method to evaluate the right hemidiaphragm mobility in healthy young adults. Methods: Forty-one healthy subjects were selected, with age range between 20 and 30 years. The participants of the study were underwe

20. Prediction of large esophageal varices in cirrhotic patients using classification and regression tree analysis
OBJECTIVES: Recent guidelines recommend that all cirrhotic patients should undergo endoscopic screening for esophageal varices. That identifying cirrhotic patients with esophageal varices by noninvasive predictors would allow for the restriction of the performance of endoscopy to patients with a high risk of having varices. This study aimed to develop a deci

21. Interobserver variability of ultrasound parameters in portal hypertension
The aim of this study was to assess interobserver agreement of ultrasound parameters for portal hypertension in hepatosplenic mansonic schistosomiasis. Spleen size, diameter of the portal, splenic and superior mesenteric veins and presence of thrombosis and cavernous transformation were determined by three radiologists in blinded and independent fashion in 3

22. Análise da expressão do receptor do fator de crescimento epitelial (EGFR) em pacientes portadores de adenocarcinoma pancreático submetidos a tratamento cirúrgico com intuito curativo / EGFR expression in pancreatic cancer patients submitted to surgical resection
INTRODUCTION: Pancreatic cancer is one of the main cancer related deaths in the world and its incidence is similar to its mortality. Biological aggressiveness and delayed diagnosis are a major concern. Adjuvant treatment has little impact on survival and the expression of potential target molecules has been undertaken in order to increase survival. OBJECTIVE

23. Treatment with mebendazole is not associated with distal migration of adult Angiostrongylus costaricensis in the murine experimental infection
Abdominal angiostrongyliasis is a zoonotic infection produced by a metastrongylid intra-arterial nematode, Angiostrongylus costaricensis. Human accidental infection may result in abdominal lesions and treatment with anti-helminthics is contra-indicated because of potential higher morbidity with excitement or death of worms inside vessels. To evaluate the eff

24. RelaÃÃo dos achados endoscÃpicos e dopplerfluxomÃtricos na colopatia da hipertensÃo porta da esquistossomose mansÃnica: estudo longitudinal
The relationship between colonoscopic features, histopathologic changes and Doppler ultrasound measurements in colonic mucosal, in patients with hepatosplenic schistosomiasis, before and after splenectomy and ligature of the left gastric vein was analysed. The study was performed using colonoscopy and Doppler ultrasonography. Sixteen patients were divided in
