Intraparenchymal distribution of the hepatic arteryin Sex-banded armadillo (Euphractus sexcinctus) and Nine-banded armadillo (Dasypus novencinctus)&

Abstract

The armadillo is a xenárthrico mammal along with anteaters and arboreal sloths. Morphological aspects of the organs of these animals are lacking of information as a basis for clinical wild animals. Thus, this research aims to describe the arterial distribution of the hepatic parenchyma of sex-banded armadillo and nine-banded armadillo, assuming your liver lobation. Altogether were used 10 animals victims of poaching and donated to UFPI with permission of the SISBio. They were dissected and we proceeded with the injection of Neoprene latex red dyed in the abdominal aorta to visualize the hepatic arterial branch. Finally, the armadillos were fixed in formaldehyde solution buffered 10 % and underwent dissection for analysis of results. The liver of both species has four lobes: right, left , with their square and caudate caudate and papillary processes , and the presence of gallbladder.  From hepatic artery in armadillos analyzed, this sends branches that will ventricularizing the liver, initial and final portions of the duodenum and pancreas. When entering the hepatic hilum, the artery presents distributed into two main branches, right and left, where each will infer the presence of segmentation own blood in the hepatic lobes, thus characterizing the anatomical and surgical arterial segmentation. Furthermore, there is a close relationship between diet and metabolism in liver morphology and vascular distribution for this organ.
