Abstract

v.12, n. 2, p.371-375, abr./jun. 2011Objetivou-se descrever a origem e ramificação das artérias mesentéricas cranial e caudal no cágado-debarbicha e, assim, fornecer subsídios para procedimentos clínicos e cirúrgicos. Foram utilizados cinco espécimes de Phrynops geoffroanus de vida livre, que se encontravam alojados no Laboratório de Ensino e Pesquisa em Animais Silvestres da Universidade Federal de Uberlândia e que foram a óbito por causas naturais. Após extração de parte da carapaça para identificação das estruturas internas, a artéria aorta foi canalizada e preenchida por látex sintético. A artéria mesentérica cranial se originou da artéria aorta e ramificou-se em artérias jejunais, artéria pancreaticoduodenal caudal e artéria ileocólica. A artéria mesentérica caudal se subdividiu em dois ramos, um cranial e outro caudal, e também teve sua origem na porção final da artéria aorta. O ramo cranial dessa estrutura se uniu à artéria ileocólica na face dorsal do cólon-reto. _______________________________________________________________________________________________________________________ ABSTRACT _______________________________________________________________________________________________________________________ The purpose of this study was to describe the origin and branching of the cranial and caudal mesenteric arteries in geoffroy's side-necked turtle and to provide support on medical and surgical procedures. Five turtles from the Phrynops geoffroanus specie, from the Laboratory of Research in Wild Animals, which died of natural causes were used. The aorta artery was cannulated and filled with synthetic latex, and the plastron was removed to visualize the turtles´internal structures. The cranial mesenteric artery arises from the aorta and it branches into jejunal artery, ileocolic artery and caudal pancreaticoduodenal artery. The caudal mesenteric artery divides into two branches, a cranial one and a caudal one, and it also has its origin in aorta arteNry. The cranial branch structure binds itself to the ileocolic artery on the dorsal surface of the colon-rectum
