Abstract
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.
