Two different models of extrahepatic portal obstruction were prepared in dogs to examine the development of portosystemic collateral pathways. The collateral pathways that developed were of two main types, portosplenic communications with the azygos system and a direct communication between the portal vein complex and the intrathoracic part of the inferior vena cava (IVC). This direct communication between the portal venous system and the IVC was unknown to us prior to these studies. The channel we describe has a potential for directly inducing pulmonary embolism, a possibility not seriously considered so far.
在犬类动物中制备了两种不同的肝外门静脉阻塞模型,以研究门体侧支循环通路的形成。所形成的侧支循环通路主要有两种类型,即与奇静脉系统的脾门交通支以及门静脉复合体与下腔静脉胸段之间的直接交通支。在这些研究之前,我们并不知晓门静脉系统与下腔静脉之间的这种直接交通支。我们所描述的这个通道有可能直接引发肺栓塞,而这一可能性到目前为止尚未得到认真考虑。
