Ultrassonografia abdominal em Saguinus Ursulus.

Abstract

The classification of Saguinus ursulus as a new taxon evidenced the lack of data in the literature on the anatomical and physiological specificities of the species, as well as its possible vulnerability caused by the degradation of its native area. In this way, we aimed to determine the ultrasonographic parameters of normal structures and organs of the species. Nine healthy primates housed at the National Primate Center (CENP) were evaluated through pelvic-abdominal ultrasonography to describe the topography, morphology, and biometrics of the abdominal and pelvic organs. The bladder was flattened dorsi-ventrally with hyperechoic walls well delimited and anechoic content; kidneys located in the retroperitoneal region, more cranial and oval right and triangular left kidney; cranial spleen to the left, fusiform and hypoechoic kidney; stomach caudal to the liver and medial to the spleen, with the five layers visible; cranial liver to the stomach and caudal to the diaphragm within the costal border, sharp edges, coarse ecotexture, hypoechoic to isoechoic in relation to the cortex of the right kidney; gallbladder positioned medially in the xiphoid region, rounded, may be bilobated or not, well defined hyperechoic walls and anechoic content; duodenum located medial to the right kidney, only three of the five layers (mucosa, mucosa and submucosa) were visualized; uterus in pelvic region, with pyriform shape and three well defined layers (myometrium, endometrium and lumen); ovaries close to the uterus, ellipsoids, homogeneous to heterogeneous ecotexture, hypoechoic with or without follicles, follicle observed with rounded shape, well delimited walls and anechoic content; testicles located in the scrotum showing finely coarse ecotexture and increased echogenicity, the mediastinum line was visualized in an animal. The pelvic-abdominal ultrasound study in the species is unheard of and may support subsequent studies for conservation and veterinary care.
