Resumo
O estudo da veia porta quanto aos vasos confluentes para sua formação e suas tributárias foi efetuado em 10 cutias (Dasyprocta aguti), adultas (3 fêmeas e 7 machos), nas quais o sistema desta veia foi injetado com látex corado, sendo a seguir fixadas em formol a 10% e dissecadas. Verificou-se que o tronco da veia porta origina-se sempre pela confluência de duas raízes, sendo representadas em 90% dos casos, pela veia lienal e pelo tronco mesentérico comum, constituído pelas veias mesentéricas cranial e caudal e, em 10%, pela veia lienal e pela veia mesentérica cranial. O tronco da veia porta recebe como tributárias a veia pancreaticoduodenal cranial (100%), a veia gástrica direita (90%) e, ainda, a veia gastroepiplóica direita (40%).
The study of portal vein concerning the confluent vessels to its formation and its tributaries was carried out in adult agouties (3 females and 7 males), the venous system of which was infected with colored latex and fixed in 10% formol. After dissection, it was noted that the trunk of the portal vein has its origin in the confluence of two roots, represented in 90% of the cases, by the lienal vein and by the common mesenteric trunk, composed by cranial and caudal mesenteric veins and, in 10%, by lienal vein and by cranial mesenteric vein. The trunk of the portal vein has as its tributaries the cranial pancreaticoduodenal vein (100%), the right gastric vein (90%), and the right gastroepiploic vein (40%).
