The purpose of this work was to evaluate the sectorial and segmental arterial branching (second- and third-order branching) in the right and left hemilivers, as knowledge of this branching should lead to improved vascular mapping for various endovascular procedures in the liver. The study was conducted on 100 formalin-fixed adult cadaveric livers. The arterial anatomy of the liver was dissected from the origin of the hepatic arteries to their segmental branches. Conventional segmental branching of both the right and the left hepatic arteries was seen in only 25% of the livers. In the remaining livers, the segmental branching of one or both of the hepatic arteries was different from that given in anatomy texts. The branching of the right and left hepatic arteries was anatomically classified into seven and six patterns, respectively, mainly on the basis of their sectorial and segmental anatomy. The present study details the highly diverse segmental arterial anatomy of the liver. The information provided here has important implications for procedures that involve selective catheterization of segmental arteries.
这项工作的目的是评估左右半肝的扇形和节段性动脉分支（二级和三级分支），因为了解这种分支情况有助于改进肝脏各种血管内手术的血管造影。该研究对100个用福尔马林固定的成人尸体肝脏进行。从肝动脉起点至其节段分支对肝脏的动脉解剖结构进行了解剖。仅25%的肝脏呈现出左右肝动脉的传统节段性分支。在其余肝脏中，一条或两条肝动脉的节段性分支与解剖学教科书所述不同。左右肝动脉的分支主要根据其扇形和节段性解剖结构在解剖学上分别分为七种和六种模式。本研究详细阐述了肝脏节段性动脉解剖结构的高度多样性。此处提供的信息对于涉及节段性动脉选择性插管的手术具有重要意义。
