【摘要】：目的解剖观测胎肝门静脉、肝固有动脉、胆总管十二指肠上段、脐静脉及静脉导管，为临床辅助性胎肝移植提供解剖学资料。方法选择５６例经福尔马林固定的正常胎儿，解剖显露门静脉、肝固有动脉、胆总管十二指肠上段、脐静脉、静脉导管，测其长度和压扁外径。结果脐静脉、门静脉、肝固有动脉、胆总管十二指肠上段、静脉导管长度分别为４５．２±９．２ｍｍ、２０．１±３．３ｍｍ、１６．３±２．８ｍｍ、１７．２±３．１ｍｍ、１３．１±２．５ｍｍ；直径分别为３．４±０．５ｍｍ、３．０±０．４ｍｍ、１．８±０．２ｍｍ、１．８±０．２ｍｍ、３．０±０．３ｍｍ。结论胎肝血供丰富，在供血管道中以脐静脉最粗，门静脉次之，肝固有动脉最细。因此，在辅助性胎肝移植时可选用脐静脉代替门静脉，以门静脉替代肝固有动脉。同时，在胎肝移植前，应结扎静脉导管，以保证肝脏足够的血供。
[Abstract]:Objective to provide anatomical data for clinical assisted fetal liver transplantation by anatomical observation of portal vein, hepatic artery, upper segment of common bile duct and duodenum, umbilical vein and venous catheter. Methods 56 normal fetuses fixed by formalin were dissected to expose portal vein, hepatic artery, upper segment of bile duct and duodenum, umbilical vein and catheter of vein. Results the length of umbilical vein, portal vein, hepatic proper artery, upper segment of common bile duct and duodenum were 45.2 卤9.2 mm, 20.1 卤3.3 mm, 16.3 卤2.8 mm, 17.2 卤3.1 mm and 13.1 卤2.5 mm, respectively, and the diameter were 3.4 卤0.5 mm, 3.0 卤0.4 mm, 1.8 卤0.2 mm, 3.0 卤0.3 mm and 3.0 卤0.3 mm, respectively. Conclusion the fetal liver is rich in blood supply, the umbilical vein is the thickest, the portal vein is the second, and the hepatic proper artery is the thinnest. Therefore, umbilical vein can be used to replace portal vein and portal vein to replace hepatic artery in auxiliary fetal liver transplantation. At the same time, before fetal liver transplantation, vein catheter should be ligated to ensure adequate blood supply to the liver.
