Anatomy of the liver (a05.8. 01. 001): worldwide review, 2019: new findings, concepts and definitions support a division of the liver into seven portal segments

Int. j. morphol; 37 (3), 2019
Due to a lack of consensus on the description of the human liver anatomy, we decided to explore different researches worldwide. Studies are focused on the hepatic vascularization. The results obtained through serial dissections in embryos, fetuses and adults have contributed to new definitions. Researche...

Hypoxic hepatitis in an extensive aortic disecction: case report

Hypoxic hepatitis is an uncommon cause of hepatic damage characterized by a centrolobular necrosis. Its pathophysiology remains unclear. Aortic dissection is a rare but frequently catastrophic event. It is caused by an aortic intimal tear with propagation of a false channel in the media. Depending on the...

A new organ preservation solution for static cold storage of the liver. Amniotic fluid

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate the effect of amniotic fluid in liver preservation in organ transplantation, and compare it with standard preservation solutions. Methods: The groups consisted of Group 1: Ringer Lactate (RL) group, Group 2: HTK group, Group 3: UW group, Group 4: AF group. The livers of ra...

Splenic ischemic preconditioning attenuates oxidative stress induced by hepatic ischemia-reperfusion in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: To evaluate the effects of splenic ischemic preconditioning (sIPC) on oxidative stress induced by hepatic ischemia-reperfusion in rats. Methods: Fifteen male Wistar rats were equally divided into 3 groups: SHAM, IRI and sIPC. Animals from IRI group were subjected to 45 minutes of part...

Effect of sevoflurane pretreatment in relieving liver ischemia/reperfusion-induced pulmonary and hepatic injury

Acta cir. bras; 34 (8), 2019
Abstract Purpose To investigate the effect of sevoflurane preconditioning on ischemia/reperfusion (I/R)-induced pulmonary/hepatic injury Methods Fifty-one Wistar rats were randomly grouped into sham, I/R, and sevoflurane groups. After reperfusion, the structural change of the lung was measured by Smi...

Evaluation of the therapeutic effect of methylene blue on the liver of rats submitted to ischemia and reperfusion

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To analyze the effect of methylene blue (MB) therapy during the liver ischemia-reperfusion injury (I/R) process. Methods: Thirty-five male Wistar rats were used, (70%) submitted to partial ischemia (IR) or not (NIR) (30%) were obtained from the same animal. These animals were divided ...

Effects of propofol pretreatment on myocardial cell apoptosis and SERCA2 expression in rats with hepatic ischemia/reperfusion

Rev. bras. anestesiol; 68 (6), 2018
Abstract Introduction: Hepatic ischemia-reperfusion injury is a common pathophysiological process in liver surgery. Whether Propofol can reduce myocardial ischemia-reperfusion injury induced by hepatic ischemia-reperfusion injury in rats, together with related mechanisms, still needs further studies. O...

Effects of different periods of gastric ischemia on liver as a remote organ

Acta cir. bras; 33 (11), 2018
Abstract Purpose: To evaluate the hepatic changes associated with gastric ischemia. Methods: Thirty male rabbits were studied, distributed in 3 groups (n=10). Group 1: ligature and section of the gastric vasculature and removal of the liver after three hours; Group 2: ligature and section of the gast...

Topical hepatic hypothermia associated with ischemic preconditioning. Histopathological and biochemical analysis of ischemia reperfusion damage in a 24 hour model

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To develop a new 24 hour extended liver ischemia and reperfusion (LIR) model analyzing the late biochemical and histopathological results of the isolated and combined application of recognized hepatoprotective mechanisms. In addition, we used a new stratification with zoning to classi...

Rivastigmine prevents injury induced by ischemia and reperfusion in rat liver

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate whether pre-treatment with rivastigmine is able to attenuate the I/R induced lesions in rat liver. Methods: SHAM animals or those submitted to I/R, non-treated or pre-treated with rivastigminine (2mg/kg) either 50 or 15 minutes before ischemia, were used. After I/R proto...
