肝尾状叶的外科解剖及其临床应用

在42例成人肝脏标本上，研究了肝尾状叶的形态，动脉、静脉和肝管的分布特征；尾状叶常有3个突起，即尾状突、乳头突和下腔静脉后突，且变异较大；尾状叶有两个恒定的蒂，其结构排列由浅入深分别是门静脉支、肝动脉支和肝管。尾状叶静脉有2～5支，其中以3支居多，主要汇入下腔静脉肝后段的中、下1／3部的左前壁。中结合解剖学研究总结了施行肝尾状叶肿瘤切除术的方法和经验。

The Study of Applied Anatomy of the Caudate Lobe of Liver

On 42 adult livers the caudate lobe of the liver was studied and the vasular,biliary channels, the pedicle and hilum of caudate lode were observed.The caudate lobe was an independent part stradling the right and left lobe of the liver and was characterized by the papillary process, caudate process and retrocaval process, which was variable. Our study confirmed that there were 2 constant pedicles of caudate lobe, in which were portal branch , arterial branch and biliary drainage. The number of veins of caudate lobe varied from 2 to 5 . It emptied mainly into the antero - left side of the middle and lower part of the retrohepatic inferior vena cava.Based on anatomic knowledge and clinic operation,the problem of excision of caudate lobe of the liver was discussed.
