In this essay we use clinical evidence and knowledge of anatomy to examine the relationship between blood flow and formation of congenital extrahepatic portosystemic shunts in dogs and cats. First we report on the clinical findings in a series of 50 dogs and 10 cats and then systematically review peer-reviewed data on the detailed anatomy of shunts in dogs and cats. In dogs four types of shunt: spleno-caval, left gastro-phrenic, left gastro-azygos and those involving the right gastric vein account for 94% of extrahepatic shunts. Cats also exhibit four types of shunt: spleno-caval, left gastrophrenic, left gastro-caval and left gastro-azygos, and the first three of these account for 92% shunts in this species. Our findings lead us to propose that preferential blood flow influences the subsequent formation of one of a number of defined and consistent congenital extrahepatic portosystemic shunts in dogs and cats.
在本文中，我们运用临床证据和解剖学知识来研究犬猫先天性肝外门体分流的血流与形成之间的关系。首先，我们报告了一系列50只犬和10只猫的临床发现，然后系统地回顾了同行评审的关于犬猫分流详细解剖结构的数据。在犬中，四种类型的分流：脾腔分流、左胃膈分流、左胃奇静脉分流以及涉及右胃静脉的分流占肝外分流的94%。猫也表现出四种类型的分流：脾腔分流、左胃膈分流、左胃腔分流和左胃奇静脉分流，其中前三种占该物种分流的92%。我们的研究结果使我们提出，优先血流会影响犬猫中一些明确且一致的先天性肝外门体分流中某一种的后续形成。
