肝门静脉左支分支分型的数字化研究及编码分析
|
摘要
目的探究肝门静脉左支新的分型和研究方法,为肝数字解剖研究提供数据和参考。方法应用Hisense CAS对110例国人上腹部增强CT数据进行肝血管三维重建,准确显示肝门静脉左支的三维图像。分析肝门静脉左支分支的形态特点及分布规律,进行编码并统计分析。结果根据门静脉左支走行特点可分为6型:Ⅰ型61例(55.45%),Ⅱ型29例(26.36%),Ⅲ型13例(11.82%),Ⅳ型4例(3.64%),Ⅴ型2例(1.82%),Ⅵ型1例(0.91%)。结论 Hisense CAS能够准确地显示肝门静脉三维影像,方便进行肝内管道观察,为肝门静脉分支分型的数字解剖学研究提供了很好的工具;针对较大数据的观测,用编码的方法非常方便统计分析。
Objective To seek the new classification and research methods of the left hepatic portal vein, and to provide data and reference for the digital anatomic research of the liver. Methods Hisense CAS was used to reconstruct the liver vessels on upper abdomen enhanced CT data in 110 cases, and the threedimensional images of the left branch of the portal vein were accurately displayed. The morphological characteristics and distribution of the left branch of the hepatic portal vein were investigated, and then encoded and statistically analyzed. Results According to the characteristics of the left branch of the portal vein, it can be divided into 6 types of codes: type Ⅰ in 61 cases(55.45%), type Ⅱ in 29 cases(26.36%), type Ⅲ in 13 cases(11.82%), type Ⅳ in 4 cases(3.64%), type Ⅴ in 2 cases(1.82%), type Ⅵ in 1 case(0.91%).Conclusions Hisense CAS can accurately display the three-dimensional image of the hepatic portal vein,which is convenient for observing intrahepatic ducts. It provides excellent tools for digital anatomic study of hepatic portal vein branching. For large data observation, the coding method is very convenient for statistics analysis.
