The celiac trunk normally has three branches; i.e. the left gastric, splenic, and common hepatic artery. It is known that the right hepatic artery occasionally branches from the superior mesenteric artery, while the cystic artery arising from the superior mesenteric artery is extremely rare. A deeper understanding of cystic arterial variations is necessary for all physicians performing examinations and surgical procedures of the hepatobiliary system.
The cystic artery arising from the superior mesenteric artery was found in the cadaver of an 86-year-old woman during an anatomy dissection class at Aichi Medical University in 2015. In this case, the cystic artery ran along the dorsal side of the portal vein through Calot's triangle to the gallbladder. The celiac trunk had four abnormal branches, one each to the left gastric, right hepatic, splenic, and left hepatic artery. The middle colic artery was absent and the left colic artery branching from the inferior mesenteric artery was distributed along the whole length of the transverse colon. In all cases of the cystic artery arising from the superior mesenteric artery, the vessel ran along the dorsal side of the portal vein; in addition, the right hepatic artery arose from the superior mesenteric artery.
腹腔干通常有三个分支，即胃左动脉、脾动脉和肝总动脉。已知右肝动脉偶尔发自肠系膜上动脉，而发自肠系膜上动脉的胆囊动脉极为罕见。对于所有进行肝胆系统检查和手术的医生来说，深入了解胆囊动脉变异是必要的。
2015年在爱知医科大学解剖课上，在一名86岁女性尸体中发现了发自肠系膜上动脉的胆囊动脉。在该病例中，胆囊动脉沿门静脉背侧经胆囊三角走行至胆囊。腹腔干有四条异常分支，分别供应胃左动脉、右肝动脉、脾动脉和左肝动脉。中结肠动脉缺如，发自肠系膜下动脉的左结肠动脉沿横结肠全长分布。在所有发自肠系膜上动脉的胆囊动脉病例中，该血管均沿门静脉背侧走行；此外，右肝动脉发自肠系膜上动脉。
