Liver ischemia and reperfusion injury. Pathophysiology and new horizons in preconditioning and therapy

Acta cir. bras; 33 (8), 2018
Abstract It is well known that during hepatic operative procedures, it is often critical that the irrigation is interrupted to avoid possible bleeding, blood transfusions, variable intensities, and their short and long-term consequences. It was believed in the past that the flow interruption should not e...

Hepatitis isquémica fulminante inducida por disfunción cardiaca severa: reporte de caso

La hepatitis isquémica es una entidad infrecuente en la práctica clínica diaria con una prevalencia de 0,16 a 0,5% entre los pacientes admitidos en unidad de cuidados críticos, asociado a una mortalidad aproximada en el 60% de los casos. Esta hepatopatía se caracteriza por un incremento rápido y ma...

Is the early or delayed remote ischemic preconditioning the more effective from a microcirculatory and histological point of view in a rat model of partial liver ischemia-reperfusion?

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To compare early- and late-effect remote ischemic preconditioning (RIPC) by analysing the microcirculatory, hemodynamic and histological changes in partial liver ischemia-reperfusion of rats. Methods: 60-minute partial liver ischemia followed by 120-minute reperfusion was performed ...

Automatic 3D modeling of liver segments including segmental branches of portal triad and hepatic vein based on the sectioned-images

Int. j. morphol; 36 (2), 2018
SUMMARY: The liver dimensional (3D) models, consists of eight segments including portal triad (portal vein, hepatic artery, and bile duct), are necessary because it is difficult to dissect a liver and its inner structures. But it is difficult to produce 3D models from high resolution and color sectioned-...

Porción hepática izquierda (A05. 8. 01. 037)

Int. j. morphol; 36 (1), 2018
RESUMEN: El conocimiento anatómico es necesario para la cirugía hepática. Los conocimientos acerca de la porción izquierda del hígado que aparecen en los textos de anatomía, cirugía y en la Internet deben ser mejorados y enriquecidos, proponemos hacerlo con este trabajo. Se estudiaron 286 hígados...

Repeatability of the "flash-replenishment" method in contrast-enhanced ultrasound for the quantitative assessment of hepatic microvascular perfusion

Braz. j. med. biol. res; 51 (4), 2018
This study aimed to evaluate the feasibility and repeatability of the flash-replenishment method in contrast-enhanced ultrasound (CEUS) perfusion imaging and assess quantitatively microvascular perfusion in the liver. Twenty healthy New Zealand rabbits were submitted to CEUS perfusion imaging with contin...

Prophylactic application of laser light restores L-FABP expression in the livers of rats submitted to partial ischemia

Clinics; 73 (), 2018
OBJECTIVES: The objective of the present study was to evaluate the protective effect of pre-conditioning treatment with laser light on hepatic injury in rats submitted to partial ischemia using mitochondrial function and liver fatty acid binding protein as markers. METHODS: Rats were divided into four g...

Perconditioning associated to hypertonic saline solution on liver function improvement after ischemia/reperfusion injury

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To evaluate the effects of hypertonic saline solution associated to remote ischemic perconditioning in liver ischemia/reperfusion injury in rats. Methods: 25 male rats (Wistar) were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of live...

Erdosteine ameliorates the harmful effects of ischemia-reperfusion injury on the liver of rats

Acta cir. bras; 32 (10), 2017
Abstract Purpose: To investigate the potential protective effects of erdosteine against the harmful effects of ischemia-reperfusion injury on the liver in an experimental rat model. Methods: Forty rats were divided into 4 groups. In the sham group, only the hepatic pedicle was mobilized. No other mani...

Atorvastatin can prevent hepatic remote reperfusion injury

ABCD (São Paulo, Impr.); 30 (3), 2017
ABSTRACT Background: Some studies have shown that statins have a promising effect on protection against reperfusion injury. Aim: To evaluate the ability of ischemic postconditioning, statins and both associated to prevent or minimize reperfusion injury in the liver of rats subjected to ischemia and rep...
