Formation of the portal venous system in Chinchilla lanigera
Keywords:Anatomy, Portal vein, Chinchilla lanigera
AbstractThe study regarding the formation of the system portal vein (VP) in chinchilla (Chinchilla lanigera) was obtained through the analysis of 10 specimens in which the extra-hepatic portal system suffered injection of red-faced latex, following by dissection in estereolupa. Thereafter outlines were made starting from the observed results, where it was discovered that VP is always originated from the confluence of two roots. The first of these roots is the truncus mesentericus communis (TM), formed from the union of the vena mesentericas cranialis and mesenterica caudalis. TM still receives as tax the vena pancreaticoduodenalis cranialis and gastroepiploica sinistra. The second root, with smaller caliber, is the vena lienalis. This description was observed in 100% of the specimens staying constant, suggesting that the obtained results can be considered as standard model.
