The anatomy of hepatic arteries is one of the most variable. Accurate awareness of all the possible anatomic variations is crucial in the upper GI surgery and especially in liver and pancreas transplantation. The most frequent anatomical variants are: a replaced or accessory right hepatic artery (RHA) from the superior mesenteric artery (6.3-21 %), a replaced or accessory left hepatic artery (LHA) from the left gastric artery (LGA) (3-18 %) or a combination of these two variants (up to 7.4 %). Herein, we describe the case of a 67-year-old cadaveric organ donor who presented a RHA originating from the splenic artery (SA) associated with both a CHA originating from the celiac trunk (CT) and a LHA originating from the LGA.
肝动脉的解剖结构是最具变异性的结构之一。准确了解所有可能的解剖变异对上消化道手术尤其是肝脏和胰腺移植至关重要。最常见的解剖变异有：发自肠系膜上动脉的替代或副右肝动脉（RHA）（6.3% - 21%）、发自胃左动脉（LGA）的替代或副左肝动脉（LHA）（3% - 18%）或这两种变异的组合（高达7.4%）。在此，我们描述一例67岁尸体器官供者的病例，该供者的右肝动脉发自脾动脉（SA），同时存在发自腹腔干（CT）的肝总动脉（CHA）和发自胃左动脉的左肝动脉。
