在成人３２例肝标本上，解剖观测了各肝静脉的长度、横径、夹角和肝静脉与相应门静脉拟分流处距各肝门的长度及穿刺距离。结果表明：肝内门—腔静脉分流术应首选肝右静脉与右门静脉及分支间穿刺，穿刺时穿刺针应与正中矢状面和下腔静脉分别呈右７５．３°±４．７°和１４０．３°±１０．２°，进入肝右静脉４．０±１．１ｃｍ，向下方或前下方推进１．８±０．９ｃｍ，即可刺入右门静脉及其分支；其次可选用肝中静脉和肝左静脉与左门静脉及分支间穿刺；当肝静脉有变异时，可选用右后下静脉与右门静脉及分支间穿刺。
In 32 adult liver specimens, the length, transverse diameter and included angle of each hepatic vein were observed. The length and puncture distance from each hepatic portal to hepatic vein and corresponding portal venous shunt were observed. The results showed that the intrahepatic portal-vena cava shunt should be the first choice between the right hepatic vein and the right portal vein and the branch, the puncture needle should be right 75.3 ° ± 4.7 ° with the median sagittal plane and inferior vena cava And 140.3 ° ± 10.2 ° into the right hepatic vein 4.0 ± 1.1cm, to the bottom of the front or forward 1.8 ± 0.9cm, you can pierce the right portal vein and its branches; followed by optional Hepatic and left hepatic veins and left portal vein and branch puncture; when the variation of the hepatic vein, the right posterior inferior vena cava and the right portal vein and the branch can be punctured.
