摘　　要：目的 解剖观测胎儿肝静脉在第二肝门入下腔静脉的形态特征。方法 选择3～10月胎儿肝脏47例，测量肝左、中、右静脉入下腔静脉处直径，记录肝静脉属支数。结果 肝左、中、右静脉压扁直径分别为0．34±0．16cm、0．38±0．21cm、0．33±0．18cm；其属支数分别为1．63±0．73个、1．93±0．79个、1．66±0．73个；下腔静脉肝上、肝下压扁直径分别为0．95±0．32cm、0．52±0．20cm，后者与前者比为0．57±014。结论 胎儿肝左、中、右静脉直径较成人细，其中肝中静脉最粗，肝左静脉次之，肝右静脉最细。肝左、右静脉分支以1支居多，肝中静脉以2支居多。胎儿肝上、肝下下腔静脉直径差异较大。Objective To dissect and observe the structure of fetal hepatic veins at the secondary porta of liver. Methods Forty seven cases of fetal livers about 3-10 months were choosen. The diameter of the left, middle and right hepatic veins joining the inferior vena cava were measured. The number of branches of them were recorded either. Results The pressed diameter of the left ,middle and right hepatic veirm were respectively 0.34± 0.16 cm,0.38 ± 0.21 cm and 0.33 ± 0.18 cm. The number of branches of them were 1.63 ± 0.73,1.93 ± 0.79 and 1.66 ± 0.73 ;The pressed diameter of inferior vena eava above and below liver were separately 0.95 ± 0.32 cm and 0.52 ± 0.20 cm. The proportion of the latter to the former was 0.57 ± 0. 14. Conclusion The diameter of fetal hepatic veins is thinner than that of adult. The middle hepatic vein is the thickest. The left hepatic vein is the second, and the right hepatic vein is the thinnest. The number of branches of the left and right hepatic veins in most proporation is one. That of the middle hepatic vein is two. There is much diversity in the diameter of inferior vena cava above and below fetal liver.
