【摘要】 试验共探查了30只山羊肝脏的门静脉在肝内的走向、分支和吻合。灌注冷的造影铸型剂为60％硫酸钡棉胶液。采用改变投照角度方法摄取立体X线片。结合解剖追综法深入观察。其结果为:(1)肝内门静脉的分支类型可划分为左叶9种类型,右叶8种类型,方叶和乳头状突7种类型尾状突6种类型。(2)按肝内门静脉分支分布密度排列的顺序是,左叶>右叶>方叶>乳头状突>尾状突。(3)肝内门静脉主要存在三种吻合形式;a)肝切迹深部分布同一区域的细分支之间存在间接吻合或直接吻合支。b).方叶上缘支与下缘支的细分支之间形成吻合桥或吻合环。c).各肝叶周缘,特别是靠近腹侧缘和外侧缘的肝叶区域许多细分支之间形成吻合网。本文还对X线造影解剖追踪法研究器官内管道分支规律的优越性进行了论述。更多还原

【Abstract】 Thw totle of 30 goats were examinek for the ramification,the anastomosis and the course of running of the portal vein in liver. Materials were injected with a collodium solution containing 60% bariu sulfate as opaque substance. Stereoroentgenography was performed by changing the projection angles of X - rays. According to the stertforoentgenographyof different angles, we made further observation with anatomy tracking method. The result shows:(1)The course of running of the intrahepatic portal vein was classified into 9 typesin the lobus sinister,8 types in the lobus dexter,7 typesin the lobus quadratus and processus papillaris,and 6 typesin the processus, (2)The five sections of the liver were arranged in the decveasing order of the density of distribution of the portal vein,as follows: lobus sinister > lobus dexter > lobus quadratus > processus papillaris > processus caudatus, (3)The intpahepatic portal vein forms the main anastomoses types:a),Direct and indirect anastondsis were found most frequently betwenn the slender branches running in the same area in the deepregion of the incisurae.b). Anastomotic nngs or bridges were formed between the slende4 branches of superior and inferior lobus quadratus predominant branches ,c). A net work was formed by anastomoses between sleder branches running in the area near the margins fo the liver,especially in the external and ventral margins of the liver.更多还原
