Coeliac trunk (CT) is the first major visceral branch of the abdominal aorta. The aim of this work was to present the CT division pattern and its anatomical variants in a sample of Polish population.
Coeliac trunk dissection was performed in 50 adult cadavers in the Department of Anatomy, Jagiellonian University Medical College. Cadavers of Polish subjects were included. Cadavers with previous upper abdominal surgery, abdominal trauma, disease process that distorted arterial anatomy or signs of putrefaction were excluded. CT variations, accessory vessels, and vertebral level of origin were described. CT patterns were reported according to the Adachi classification. This study was reviewed and approved by the local Ethics Committee.
Coeliac trunk consisting of the left gastric, common hepatic and splenic artery (type 1 according to the Adachi classification) was found in 82% of cadavers. The true tripod was found in 20% and the false one in 80%. Additional vessels were also found: greater pancreatic from the splenic artery and left inferior phrenic from the left gastric artery, which accounted for 2% sections. Type 2 according to the Adachi classification (i.e. the hepatosplenic trunk) was found in 16% of the sections. Other types of CT were not observed. The level of origin was found to be at the inter-vertebral disc between T12 and L1 in all of the cases.
Based on the analysis of the sectional material of the Department of Anatomy, it was found that the typical visceral segmental division is approximate to that observed by Adachi in its classification, whereas the second type of CT was twice as frequent and no other, less frequent types were found.
腹腔干（CT）是腹主动脉的第一个主要内脏分支。本研究的目的是展示波兰人群样本中 CT 分支模式及其解剖变异。
在雅盖隆大学医学院解剖系对 50 具成人尸体进行了腹腔干解剖。纳入了波兰受试者的尸体。排除了既往上腹部手术、腹部创伤、扭曲动脉解剖结构的疾病过程或腐败迹象的尸体。描述了 CT 变异、副血管和起源的椎体水平。根据 Adachi 分类报告 CT 模式。本研究经当地伦理委员会审查和批准。
82%的尸体中发现由左胃动脉、肝总动脉和脾动脉组成的腹腔干（根据 Adachi 分类为 1 型）。发现真正的三脚 20%，假三脚 80%。还发现了其他血管：来自脾动脉的胰大动脉和来自左胃动脉的左下膈动脉，占 2%的节段。根据 Adachi 分类（即肝脾干）的 2 型在 16%的节段中发现。未观察到其他类型的 CT。起源水平在所有情况下均位于 T12 和 L1 之间的椎间盘。
基于解剖系的节段材料分析，发现典型的内脏节段性分支与 Adachi 在其分类中观察到的分支近似，而第二种 CT 类型的频率是其两倍，且未发现其他频率较低的类型。
