No. of bitstreams: 1 2015 - Uiara Hanna Ara?jo Barreto.pdf: 2769988 bytes, checksum: cebc9db54d83f27429944a782944b7d6 (MD5) Previous issue date: 2015-06-22 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The study of the wildlife has increased because many species find themselves threatened with extinction, the Amazonian manatee (Trichechus inunguis) is classified as vulnerable. The main factors that aggravate this situation is the slow reproduction of these animals, as well as poaching, which still occurs in the Amazon region, increased the need for preservation. The study of this kind is crucial to generate knowledge about the same, contributing in an attempt to reverse your current frame. Research on diagnostic imaging for manatees are rare, especially when directed ultrasound, it is an excellent technique to be carried out in wild animals, for not being invasive and provide real time information of each body. This abdominal ultrasound research will generate normal data, in the future we can diagnose diseases. The aim of this study was to standardize the examination technique and describe the abdominal ultrasound findings in inunguis Trichechus bred in captivity, increasing knowledge about the species and consequently aid in the diagnosis of diseases. The survey was conducted with 18 animals to describe the normal sonographic anatomy in the abdominal cavity of Amazonian manatee. During abdominal scan was viewed homogeneous liver, hyperechoic contoured edges and regular; the gallbladder showed anechoic content with regular and thin wall; stomach was present gas content, hypoechoic and thin wall. In the caudal abdomen visibilizou urinary bladder in piriformis format, bit full, hyperechoic wall and content ranging from anechoic and hypoechoic. Evaluated the subcutaneous tissue, which can differentiate the layer of skin, fat, muscle and peritoneum. The ultrasound examination obtained satisfactory results in this study, concluding that an efficient technique for evaluation in Amazonian manatee / O estudo com a fauna silvestre vem crescendo devido muitas esp?cies encontrarem-se amea?adas a extin??o, como o peixe-boi amaz?nico (Trichechus inunguis) que est? classificado como vulner?vel. Os principais fatores que agravam esse quadro ? a reprodu??o lenta destes animais, al?m da ca?a predat?ria, que ainda ocorre na regi?o amaz?nica, aumentando a necessidade de preserva??o. O estudo desta esp?cie ? fundamental para gerar conhecimento sobre a mesma, contribuindo na tentativa de reverter o seu quadro atual. Pesquisas sobre diagn?stico em imagem em peixe-boi s?o raras, principalmente quando direcionada a ultrassonografia, trata-se de uma excelente t?cnica para ser realizada em animais silvestres, por n?o ser invasiva e fornecer informa??es em tempo real de cada ?rg?o. Esta pesquisa de ultrassonografia abdominal ir? gerar dados de normalidade, para no futuro conseguirmos diagnosticar patologias. O objetivo do presente estudo foi padronizar a t?cnica de exame e descrever os achados de ultrassonografia abdominal em Trichechus inunguis criados em cativeiro, aumentando o conhecimento sobre a esp?cie e como consequ?ncia auxiliar no diagn?stico de patologias. A pesquisa foi realizada com 18 animais para descri??o da anatomia ultrassonogr?fica normal em cavidade abdominal de peixe-boi amaz?nico. Durante varredura abdominal foi visualizado f?gado homog?neo, hiperec?ico com contornos e bordos regulares; a ves?cula biliar apresentou conte?do anec?ico com parede regular e fina; no est?mago estava presente conte?do gasoso, parede hipoec?ica e fina. No abd?men caudal visibilizou a ves?cula urin?ria em formato piriforme, pouco repleta, parede hiperec?ica e conte?do variando entre anec?ico e hipoec?ico. Avaliou-se o tecido subcut?neo, onde pode-se diferenciar a camada de pele, gordura, muscular e perit?nio. O exame de ultrassonografia obteve resultados satisfat?rios neste estudo, concluindo ser uma t?cnica eficiente para avalia??o em peixe-boi amaz?nico
