【摘要】 目的:系统的整理犬肝脏及其附属管道的解剖学数据,为建立各种犬动物模型提供依据.方法:戊巴比妥钠腹腔注射麻醉,取上腹部正中切口入腹,充分暴露肝脏,原位测量肝脏各叶径线及附属管道的长度和外径;切取肝脏,测量肝静脉及肝短静脉;切断各叶肝蒂,称各肝叶质量.结果:原位观察68例,测量数据62份;离体观察43例,称重资料33份.犬肝脏分为7叶,各肝叶形态、比例及质量较为恒定,具有独立的G lisson系统和肝静脉系统,肝动脉、肝静脉、胆道分支特殊,脾静脉一般分为上极和下极2支.结论:成功的建立了犬肝脏及其附属管道的解剖学数据库,为以后建立各种犬动物模型奠定了基础.更多还原

【Abstract】 AIM: To collect systematically the anatomic data of canine liver and affiliated conduits and provide a foundation for making a variety of canine models.METHODS: The dogs were anesthetized with pentobarbital sodium(30 mL/L,1 mL/kg) through intraperitoneal injection.After abdomen was open with median incision in epigastric zone,liver was exposed sufficiently to measure the diameter of each hepatic lobe and the length and external diameter of liver affiliated conduits in natural or normal position.The liver was taken out of abdomen for measuring the branches of hepatic vein and short hepatic vein.And then every hepatic peduncle of all hepatic lobes was cut off for weighing the hepatic lobes.RESULTS: Sixty-eight canine livers and affiliated conduits were observed and 62 were measured in natural or normal position;43 canine livers were observed and 33 were measured ex vivo.The canine liver is constituted by 7 lobes;that is left lateral lobe,left central lobe,quadrate lobe,right central lobe,right lateral lobe,caudate lobe and lingual lobe.The shape and proportion of hepatic lobes are comparatively constant.Each lobe has its independent Glisson system and hepatic vein system. The branches of the hepatic artery,hepatic vein,biliary tract and splenic vein of canine liver are particular.Splenic vein commonly is composed of 2 branches: upper pole and lower pole.(CONCLUSION:) We have succeeded in establishing anatomic database of canine liver and affiliated conduits,which makes a foundation for establishing various canine models.更多还原
