SUMMARY: Liver transplantation (LT) is the treatment of choice for decompensated liver cirrhosis. In the LT procedure, an adequate arterial supply is required for anastomosis to prevent postoperative necrosis and maintain hepatic parenchymal functions. The extrahepatic arterial system is primarily respon...
RESUMEN: El objetivo de este trabajo es analizar las variantes de la arteria hepática observadas en hígados de donantes cadavéricos empleados para trasplante ortotópico de hígado en nuestra población. Se efectuó un estudio retrospectivo de una cohorte de 140 trasplantes entre junio del año 2011 y...
SUMMARY: Liver plays an important role in many events such as bile production, blood filtration and metabolic functions. The liver is supplied by the hepatic arterial system. The hepatic arterial system anatomy has a variable structure and the rate of variation is high. In our study, we aimed to determin...
SUMMARY: The celiac trunk is the first major unpaired branch of the abdominal aorta found at the twelfth vertebral level (T12). It gives off branches supplying the spleen, liver and the stomach. However, the branching patterns of the celiac trunk tend to vary by population throughout the world. We sought...
This study aims at understanding the vascularization of the human liver to determine the correct way to divide it into "divisions" (sectors) and segments, for which we dissected 250 livers using the acrylic resin injection method. The results showed the role of the "Porta hepatis" in the hepatic vascular...
Purpose To investigate the effects of induction of selective liver hypothermia in a rodent model. Methods Seven male Wistar rats were subjected to 90 minutes of partial 70% liver ischemia and topic liver 26°C hypothermia (H group). Other seven male Wistar rats were subjected to 90 minutes of partial 70...
ABSTRACT Background: Hepatectomies promote considerable amount of blood loss and the need to administrate blood products, which are directly linked to higher morbimortality rates. The blood-conserving hepatectomy (BCH) is a modification of the selective vascular occlusion technique. It could be a surgic...
Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepa...
Abstract Purpose: To evaluate that Connexin (Cx43) plays a role in lesions after hepatic ischemia/reperfusion (IR) injury. Methods: We use Cx43 deficient model (heterozygotes mice) and compared to a wild group. The groups underwent 1 hour ischemia and 24 hours reperfusion. The heterozygote genotype was...
