肝脏B型超声断面解剖初步研究

<正> B型超声在临床已广泛应用,搞清肝脏B型超声常用声束方向的各种方位断面解剖,对肝病超声诊断颇有参考价值。肝脏B型超声断面解剖国内已有报导,但例数均较少,而且肝脏大小、形态以及内部管道系统个体差异较大,尚需积累大量资料,进行观察和研究,从而得出一个较有普遍性规律,更好地应用于临床,这就是本文研究的目的。

Preliminary Study on the Sectional Anatomy of the Liver by Wode-B Supersonic

According to the direction of sonic beamype for the diagnosis of the liver, ten hepatic sections (including four directions) were made. The results are as follows: 1. The hepatic cross section, which is 1cm under the xiphoid process, was cut. The section was indentical with the sagittal part of the left branch of the portal vein and three hepatic veins could be seen in this section. Thus, it is the best section for the dividing of the hepatic segments. 2. The biggest inclined section of the right hepatic lobe: The right branch of the portal vein was found in the centre of the section. The gallbladder was in front of the right branch and the inferior vena behind the right branch. For this reason, this section is an important section. 3. The sagittal hepatic section: The features of blood vessels distribution in the sections are that hepatic veins are located in the posterior and superior portion and that the portal vein lies in the anterior and inferior portion. The size of the left and the right lobe can be measured at these sections respectively.
