The celiac trunk (CT) is the first major branch of the abdominal aorta and typically gives rise to the left gastric artery (LGA), common hepatic artery (CHA), and splenic artery (SA), which supply blood to the abdominal viscera. Variations in the branching pattern of the CT exist and knowledge of such is crucial when performing surgical, laparoscopic, and angiographic procedures. The aim of this study is to determine the anatomic variations of the CT in adult Filipino cadavers and to compare the proportions of these with those reported in the foreign literature.
Adult Filipino cadavers from the University of the Philippines College of Medicine Anatomy Laboratory were dissected by first year medical students from 2014-2019. The CT and its branches were identified, drawn on a separate piece of paper, and confirmed to be correct and accurate by an anatomist. The data collected from that period was reviewed. Percentages were calculated for the branching patterns identified. A Z-test of Two Populations was used to compare the results of the current study to that of Pinal-Garcia (2018), Pillay (2020) and Venieratos (2013).
A total of 107 drawings based on 107 dissected preserved cadavers were reviewed. Ninety-two specimens (85.98%) showed typical branching into the LGA, CHA, and SA. The CT presented as a true tripod in 75 specimens (70.09%) and as a bifurcation with one of the three arteries arising first along the trunk (false tripod) in 17 specimens (15.89%). Nine cadavers (8.41%) showed additional branches arising from the CT and four (3.74%) showed bifurcation of the CT with the third branch arising from a different artery.
The most common configuration of the CT among Filipino adult cadavers is a true tripod, followed by a false tripod, additional branching, and bifurcation of the CT with the third branch arising elsewhere. The present study most closely resembles the results of the study of Venieratos.
腹腔干（CT）是腹主动脉的第一大分支，通常分出胃左动脉（LGA）、肝总动脉（CHA）和脾动脉（SA），为腹部脏器供血。CT的分支模式存在变异，了解这些变异在进行外科手术、腹腔镜手术和血管造影手术时至关重要。本研究的目的是确定成年菲律宾尸体中CT的解剖变异，并将这些变异的比例与国外文献报道的比例进行比较。
2014年至2019年，菲律宾大学医学院解剖学实验室的成年菲律宾尸体由一年级医学生进行解剖。识别出CT及其分支，绘制在一张单独的纸上，并由解剖学家确认正确无误。对该时期收集的数据进行回顾。计算所识别出的分支模式的百分比。使用双总体Z检验将本研究的结果与皮纳尔 - 加西亚（2018年）、皮莱（2020年）和维尼埃拉托斯（2013年）的研究结果进行比较。
共审查了基于107具解剖保存尸体绘制的107张图。92个标本（85.98%）显示典型地分支为LGA、CHA和SA。75个标本（70.09%）中CT呈现为真正的三脚架形式，17个标本（15.89%）中CT呈现为分叉，三条动脉之一首先沿主干发出（假三脚架）。9具尸体（8.41%）显示CT有额外分支，4具尸体（3.74%）显示CT分叉且第三分支从不同动脉发出。
菲律宾成年尸体中CT最常见的构型是真正的三脚架，其次是假三脚架、额外分支以及CT分叉且第三分支从其他部位发出。本研究结果与维尼埃拉托斯的研究结果最为相似。
