Normal hepatic arterial anatomy consists of the right hepatic artery and left hepatic artery branching from the common hepatic artery. Despite this being the most common configuration, many variations have been described. Here, we present a rare variant of hepatic arterial anatomy- a replaced right hepatic artery with direct aortic origin. Additionally, the patient was found to have a dorsal pancreatic artery originating from the replaced right hepatic artery This was angiographically identified during mapping for transarterial radioembolization for hepatocellular carcinoma. The unique anatomy in this case and the effect it had on transarterial radioembolization planning described herein demonstrates the necessity of understanding variant hepatic arterial anatomy in endovascular hepatic interventions.
正常肝动脉解剖结构由从肝总动脉分支出来的右肝动脉和左肝动脉组成。尽管这是最常见的结构，但已描述了许多变异情况。在此，我们展示一种罕见的肝动脉解剖变异——一条直接起源于主动脉的替代右肝动脉。此外，发现该患者有一条起源于替代右肝动脉的胰背动脉。这在肝细胞癌经动脉放射性栓塞的血管造影定位过程中得以识别。本文所述的该病例独特解剖结构及其对经动脉放射性栓塞计划的影响，证明了在血管内肝脏介入治疗中了解变异肝动脉解剖结构的必要性。
