Resumo
O estudo com a fauna silvestres vem crescendo devido ao aumento de espécies ameaçadas juntamente com a degradação ambiental. A lontra (Lontra longicaudis) é uma espécie classificada como vulnerável à extinção no Brasil, dentro deste contexto. Portanto esse estudo teve como objetivo obter referências de normalidade das imagens ultrassonográficas dos órgãos abdominais de lontra mantidas sob cuidados humanos, como em zoológicos e instituições de pesquisa legalizadas. Para tanto foram realizados exames ultrassonográficos abdominais em 09 (nove) indivíduos de Lontra longicaudis considerados hígidos pelos exames clínicos e laboratoriais. Durante a varredura ultrassonográfica foi visibilizado o estômago com conteúdo líquido, apresentando 5 (cinco) camadas e evidente projeção das pregas gástricas. O fígado de parênquima homogêneo, hiperecóico com contornos e bordos regulares em relação ao rim. A vesícula biliar foi observada com conteúdo anecóico e parede regular e fina (média 0,08cm). Na cavidade abdominal caudal visibilizou-se a bexiga em formato piriforme, de conteúdo anecogênico, parede hiperecóica (medindo entre 0,07cm e 0,19cm) e conteúdo anecóico com alguns ecos. Os rins apresentaram formato lobulado e mais hipoecogênico em relação ao parênquima esplênico e hepático. O exame de ultrassonografia obteve resultados satisfatórios neste estudo, demonstrando a eficiência da técnica para esta espécie e obtendo informações importantes de referências de imagens ultrassonográficas que poderão ser utilizadas no futuro em exames de manejo rotineiros.
The study of wild fauna has been growing due to the increase in threatened species along with environmental degradation. The otter (Lontra longicaudis) is a specialized species as vulnerable to extinction in Brazil, within this context. Therefore, this study aimed to obtain normality references for the ultrasound images of Organs abdominal organs of otters kept under human care, into zoos and legalized research institutions. For this purpose, abdominal ultrasound examinations were performed in 09 (nine) compared to Lontra longicaudis considered healthy by clinical and laboratory tests. During the ultrasound scan, the stomach with liquid content was visualized, with 5 (five) layers and evident projection of the gastric folds. The liver with a homogeneous parenchyma, hyperechoic with regular contours and borders in relation to the kiddney. The gallbladder was observed with anechoic content and a regular and thin wall (mean 0.08 cm). In the caudal abdominal cavity, the bladder was seen in a piriform shape, with anechogenic content, hyperechoic wall (measuring about 0.19cm) and anechoic content with some echoes. The kidneys are lobulated in shape and more hypoechoic in relation to the splenic and hepatic parenchyma. The ultrasonography exam obtained satisfactory results in this study, demonstrating an efficiency of the technique for this species, and obtaining vii important information from references of ultrasonographic images that can be used in the future in routine management exams.
