The aim of this study was to present an overview of variations of the hepatic artery from the origin to the segmental branching.
Abdominal Computed Tomography performed on consecutive patients in our tertiary center between 2019 and 2020 were analyzed. Hepatic arterial branching and its relationship to the portal veins were reported.
Out of 500 imaging, 16 anatomic patterns were found for the origin of hepatic artery, with 65.6% conventional origin at celiac axis (n = 328); 10 patterns for the left hepatic artery, 23 for segment IV artery, and more than 21 for the right hepatic artery (RHA), with conventional branching in respectively 66.8%, 39.6% and in 46.4% of patients. Conventional anatomy from celiac axis to segmental branching was found in 10.4% of patients.
Dedicated thin-section imaging appears to be essential for preoperative planning in liver surgery, given the high variability of arterial distribution and their surgical implications.
本研究旨在概述从起源到节段性分支的肝动脉变异。
分析了 2019 年至 2020 年在我们的三级中心进行的连续患者的腹部计算机断层扫描。报告了肝动脉分支及其与门静脉的关系。
在 500 次成像中，发现肝动脉起源有 16 种解剖模式，其中 65.6%（n=328）在腹腔干的传统起源；10 种左肝动脉模式，23 种 IV 段动脉模式，21 种以上右肝动脉（RHA）模式，分别在 66.8%、39.6%和 46.4%的患者中出现常规分支。在 10.4%的患者中发现了从腹腔干到节段性分支的常规解剖结构。
鉴于动脉分布及其手术意义的高度变异性，专门的薄层成像似乎对肝切除术的术前规划至关重要。
