Anatomical basis and clinical value of liver parenchyma transection guided by the hepatic vein        ZHENG Shu-guo. Institute of Hepatobiliary Surgery，the First Hospital Affiliated to Army Medical University(Southwest Hospital)，Chongqing 400038，China
Abstract    Liver parenchyma transection guided by the hepatic vein is the basic requirement of anatomical hepatectomy. The technique has been gradually accepted and widely used in open and laparoscopic anatomical hepatectomy. As the exact dividing plane between the hepatic segments，the hepatic vein is almost overlapping with the ischemia demarcation formed by occluding the inflow of the target hepatic segment，and these are the anatomical bases of this technique. The clinical value of the technique is mainly to guide the accurate transaction plane of the liver parenchyma，and eliminate the ineffective liver tissue lacking of inflow and / or outflow，reduce intraoperative bleeding and the incidence of postoperative complications. In clinical，the technique is mainly applied to liver resection for hepatocellular carcinoma，in which it can remove the tumor and intrahepatic micrometastases disseminating through portal vein simultaneously，reduce postoperative recurrence and improve survival rate. It can also be used in the surgical treatment of hepatolithiasis and intrahepatic bile duct dilatation which were characterized by introhepatic segment distribution of the lesions ，and to achieve a complete removal of the target lesion and maximizes the remaining functional liver.
