Keywords:Anatomy, Vein, Portal, Agouti, Rodent
AbstractThe 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%).
