This study aimed to examine the inflow and outflow vascular system of the caudate lobe and determine its relevance to hepatobiliary surgery.
A total of 41 cadaveric liver specimens were dissected in 2019 to evaluate the inflow and outflow vascular system of the caudate lobe.
The Glisson's pedicles of the paracaval portion were mainly from the right pedicle in 14 cases (34.15%), mainly from the left pedicle in 22 cases (53.66%), and equally from the left and right pedicle in 5 cases (12.19%). Many thick branches of the portal vein were found behind the plane consisting of the hilar plate and Arantius ligament, but none of them were thicker than 1 mm in front of the plane. All of the veins of the caudate lobe drained into the inferior vena cava (IVC) via the anterior face. There was an avascular zone without short hepatic veins (SHVs) consisting of loose connective tissue between the retrohepatic IVC and caudate lobe, with its length and width being 45-97 mm and 6-15 mm, respectively.
The plane consisting of the hilar plate and Arantius ligament can be regarded as the boundary between the caudate lobe and the other lobes. There is an avascular zone without SHVs consisting of loose connective tissue between the retrohepatic IVC and caudate lobe.
本研究旨在研究尾状叶的流入和流出血管系统，并确定其与肝胆外科手术的相关性。
2019年共解剖41例尸体肝脏标本，以评估尾状叶的流入和流出血管系统。
腔静脉旁部的肝蒂主要来自右肝蒂14例（34.15%），主要来自左肝蒂22例（53.66%），左右肝蒂均等的5例（12.19%）。在由肝门板和阿兰蒂乌斯韧带组成的平面后方发现许多粗大的门静脉分支，但在该平面之前均无直径超过1mm的分支。尾状叶的所有静脉均经前面汇入下腔静脉。肝后下腔静脉与尾状叶之间存在一个由疏松结缔组织构成的无肝短静脉的无血管区，其长度和宽度分别为45 - 97mm和6 - 15mm。
由肝门板和阿兰蒂乌斯韧带组成的平面可视为尾状叶与其他叶之间 的边界。肝后下腔静脉与尾状叶之间存在一个由疏松结缔组织构成的无肝短静脉的无血管区。
