The coeliac trunk (CeT) and hepatic arterial system exhibit significant anatomical variability, which holds substantial clinical and surgical relevance. This cadaveric case describes an aberrant branching pattern of the CeT discovered during the routine anatomical dissection of a 78-year-old female cadaver. Notably, the proper hepatic artery (PHA) was absent, with the left hepatic artery (LHA) arising from the common hepatic artery (CHA) before its bifurcation into the right hepatic artery (RHA) and gastroduodenal artery (GDA). In addition, the inferior phrenic arteries (IPAs) originated from a common trunk arising from the CeT. This vascular configuration deviates from the CHA trifurcation pattern, which has been previously documented in the literature but remains infrequently reported. Given the critical role of the hepatic arterial system in surgical procedures, including hepatectomy, liver transplantation, and interventional radiology, recognizing such anatomical variations is paramount to prevent intraoperative complications. This report underscores the importance of detailed preoperative imaging and thorough anatomical knowledge in optimizing surgical outcomes and patient safety.
腹腔干（CeT）和肝动脉系统表现出显著的解剖变异，这具有重要的临床和手术意义。本尸体解剖病例描述了在对一名78岁女性尸体进行常规解剖时发现的CeT异常分支模式。值得注意的是，肝固有动脉（PHA）缺如，肝左动脉（LHA）在肝总动脉（CHA）分叉为肝右动脉（RHA）和胃十二指肠动脉（GDA）之前就从CHA发出。此外，膈下动脉（IPA）起源于CeT发出的一个共同干。这种血管构型不同于文献中先前记载的CHA三分叉模式，但仍很少见报道。鉴于肝动脉系统在包括肝切除术、肝移植和介入放射学等外科手术中的关键作用，识别这种解剖变异对于预防术中并发症至关重要。本报告强调了详细的术前影像学检查和全面的解剖学知识在优化手术结果和患者安全方面的重要性。
