Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants. Herein, we describe the case of a 70 years old woman affected by IPMN of the pancreas with a quadrifurcation of CHA, associated with a RHA off the SMA.

由于肝胰胆手术的切除和重建复杂且血管解剖结构存在变异性，因此具有挑战性。肝脏的动脉血供由发自腹腔干（CT）的肝总动脉（CHA）维持。肝总动脉在距胆总管（CBD）内侧0.5 - 1厘米处分为胃十二指肠动脉（GDA）和肝固有动脉（PHA），肝固有动脉在肝门处分为右支和左支。最常见的变异是发自肠系膜上动脉（SMA）的右肝动脉（RHA）、发自胃左动脉（LGA）的左肝动脉（LHA）或这两种变异的组合。在此，我们描述了一名70岁女性胰腺导管内乳头状黏液性肿瘤（IPMN）患者的病例，该患者肝总动脉呈四分支，伴有发自肠系膜上动脉的右肝动脉。
