Knowledge of variations in arterial vascular supply is crucial in HPB and general surgery. Although the arterial configuration of the coeliac trunk and the superior mesenteric artery had been investigated, there are still arterial branching patterns to be described. We herein present the case of an 84-year-old male patient who underwent total pancreatectomy due to a not specified pancreas head tumor with a replacing right hepatic artery according to Michel's classification III and a replacing middle colic artery arising from the splenic artery and running on the ventral side of the pancreas. To the best of our knowledge, this arterial branching pattern has never been described so far. In this case, two arterial variations had been presented with a type III arterial supply according to Michel's classification, and a replacing middle colic artery arising from the SA.
了解动脉血管供应的变异情况在肝脏、胰腺和胆道外科（HPB）及普通外科中至关重要。尽管已经对腹腔干和肠系膜上动脉的动脉构型进行了研究，但仍有一些动脉分支模式有待描述。我们在此报告一例84岁男性患者，因未明确的胰头肿瘤接受了全胰切除术，根据米歇尔分类法III，其右肝动脉为替代型，且有一支替代中结肠动脉起源于脾动脉并走行于胰腺腹侧。据我们所知，这种动脉分支模式迄今从未被描述过。在该病例中，呈现了两种动脉变异，根据米歇尔分类法为III型动脉供应，且有一支替代中结肠动脉起源于脾动脉。
