应用55例成人肝剥离标本及45例胎儿、新生儿肝管道铸型,研究了肝尾状叶的鞘系及静脉回流。尾状叶有两个恒定的蒂、接受左、右侧鞘系的双重供应,以左侧为主;而尾状突主要由右后叶鞘系分布。15例肝铸型标本的尾状叶左、右侧动脉形成吻合弓。尾状叶动脉供应形式可分为三种,静脉可分为三型并直接汇入下腔静脉。由于血管吻合的存在,在病理状态下,尾状叶也应是沟通门一腔静脉的桥梁。 55 cases of adult liver dissection specimens and 45 cases of fetal, neonatal hepatic duct casting were used to study the sheath and venous return of the caudate lobe. Caudal lobe has two constant pedicle, accept the left and right sheath double supply, mainly to the left; and caudate process mainly by the right posterior sheath distribution. 15 cases of liver specimens of the caudate lobe left and right arteries to form anastomotic arch. The caudate lobe artery supply can be divided into three types, the vein can be divided into three types and directly into the inferior vena cava. Due to the existence of vascular anastomosis, in the pathological state, the caudate lobe should also be a bridge to communicate a vena cava.
