In this study, we investigated the relationship between the portal vein and hepatic artery variations and the remaining liver volume in living donors in liver transplantation.
In the study, triphasic abdominal computed tomography images of 180 live liver donor candidates were analysed retrospectively. Portal veins were divided into four groups according to the Nakamura classification and seven groups according to the Michels classification. The relationship between vascular variations and remnant liver volume was compared statistically.
According to the Nakamura classification, there were 143 (79.4%) type A, 23 (12.7%) type B, 7 (3.9%) type C and 7 (3.9%) type D cases. Using the Michels classification, 129 (71%) type 1, 12 (6.7%) type 2, 24 (13%) type 3, 2 (2.2%) type 4, 10 (5.6%) type 5, 1 (0.6%) type 6, and 2 (1.1%) type 7 cases were detected. There was no significant difference in the percentage of the remaining volume of the left liver lobe between the groups (p = 0.055, p = 0.207, respectively).
Variations in the hepatic artery and portal vein do not affect the remaining liver volume in liver transplantation donors.
在本研究中，我们调查了肝移植活体供体中门静脉和肝动脉变异与剩余肝体积之间的关系。
本研究回顾性分析了180例活体肝供体候选者的腹部三期计算机断层扫描图像。门静脉根据中村分类法分为四组，根据米歇尔分类法分为七组。对血管变异与残余肝体积之间的关系进行统计学比较。
根据中村分类法，A型143例（79.4%），B型23例（12.7%），C型7例（3.9%），D型7例（3.9%）。采用米歇尔分类法，检测到1型129例（71%），2型12例（6.7%），3型24例（13%），4型2例（2.2%），5型10例（5.6%），6型1例（0.6%），7型2例（1.1%）。各组之间左肝叶剩余体积百分比无显著差异（分别为p = 0.055，p = 0.207）。
肝动脉和门静脉的变异不影响肝移植供体的剩余肝体积。
