巨微解剖观测结果表明，肝门区的胆囊和胆囊管的血供来源是胆囊动脉，肝左、右管的主要血供来源是肝右动脉，分别占５６．２％、７１．６％。胆囊动脉尚有分支进入肝内（占７７．５％），营养肝左管（占２１．７％）、肝右管（占２５．８％）。胆囊、胆囊管、肝左、右管的营养动脉的形态持点，对于临床手术中解剖分离胆管有一定参考意义。 Giant micro-anatomical observations showed that the source of blood supply to the gallbladder and cystic duct of the hilar region was the cystic artery. The main source of blood supply to the left and right hepatic vessels was the right hepatic artery, accounting for 56.2% and 71.6% respectively. The gallbladder artery still has branches into the liver (77.5%), left hepatic duct (21.7%) and right hepatic duct (25.8%). Gallbladder, cystic duct, left and right hepatic duct morphology of nutritional artery holding point for clinical surgical dissection of bile duct has some reference value.
