As there are no exact data available which part of the bile duct should be measured, the hepatoduodenal ligament was examined in 20 cadavers. The constant anatomic relationship between the right hepatic artery and the common hepatic duct is shown. A right hepatic artery properly originating from the hepatic artery passes to 85% dorsally and to 15% ventrally of the common hepatic duct, but remains ventrally to the portal vein. If the right hepatic artery is shown dorsal to the portal vein (20%), an accessory right hepatic artery should be suggested. To maintain uniformity of measurement, the size of the common hepatic duct should be recorded immediately caudal to the right hepatic artery.
由于没有确切数据表明应测量胆管的哪一部分，因此对20具尸体的肝十二指肠韧带进行了检查。显示了右肝动脉与肝总管之间恒定的解剖关系。正常发自肝动脉的右肝动脉，85%走行于肝总管的背侧，15%走行于肝总管的腹侧，但仍位于门静脉的腹侧。如果右肝动脉显示在门静脉的背侧（20%），则应提示存在副右肝动脉。为保持测量的一致性，应在右肝动脉紧下方记录肝总管的大小。
