在42例成人肝脏标本上，研究了肝尾状叶的形态、动脉分布、静脉和肝管的引流途径以及门和蒂。尾状叶间跨于肝左、右叶之间，是相对独立的部分，带有三个突起即尾状突、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，主要汇入肝后下腔静脉中、下1／3段的左前壁。临床上3例尾状叶肿瘤安全切除。结合解剖学的研究和手术体会，讨论了尾状叶肿瘤切除时应注意的问题。
In 42 adult liver specimens, the morphology of the caudate lobe, the distribution of the arteries, the drainage routes of the veins and the hepatic duct, and the pedicle and pedicle were studied. Caudal between the leaves across the left and right lobes, is a relatively independent part of the process with three protrusions that caudate process, papillae and inferior vena cava sudden change, and greater variation. Caudate lobe has two constant pedicle, the structure of the arrangement from shallow to deep are the portal vein branch, hepatic artery branch and hepatic duct. Caudate vein veins have 2 to 5, of which 3 mostly, mainly into the inferior vena cava in the next, 1/3 of the left anterior wall. 3 cases of clinically caudate lobe tumors safely removed. Combined with anatomical researches and surgical experiences, the problems that should be paid attention to in the caudate lobe tumor resection were discussed.
