Resumo
O Estudo ultrassonográfico do ligamento nucal (LN) em equinos tem despertado grande interesse científico. O estudo ultrassonográfico do LN visa a obtenção de referências morfológicas e morfometricas e ,assim, melhorar a sensibilidade, precisão e interpretação dessa estrutura ligamentar. Realizou-se um estudo ultrassonográfico em modo B do LN de 15 equinos em 3 diferentes faixas etárias, com objetivo de padronizar valores ultrassonográficos no modo B, o grupo 1 são animais em desmama que não sofreram ações do cabresteamento, grupo dois são animais já cabresteado e gurpo 3 cabresteado e domado. Cinco animais foram contidos quimicamente com xilazina e detomidina, sendo os outros 10 contidos mecanicamente. Na análise do modo B, os valores obtidos, apresentaram diferença estatística entre o grupo 1(um), e os demais grupos. Anáise a cegas demonstrou o LN mais ecogênico do que os tecidos adjacentes. A diferença desses valores estáticos foi atribuída a faixa etária, e a ecogenicidade encontrada deve-se ao ligamento ser formado por colágeno. Desta forma, conclui-se que o exame ultrassonográfico modo B, é uma ferramenta útil para identificar alterações ligamentares na região estudada.
The ultrasound study of the nuchal ligament (NN) in horses has aroused great scientific interest. The ultrasonographic study of LN aims at obtaining morphological and morphometric references and, thus, improving the sensitivity, precision and interpretation of this ligament structure. An ultrasonographic study was performed in B mode of the LN of 15 horses in 3 different age groups, aiming to standardize sonographic values in mode B, group 1 were weaned animals that did not suffer from the actions of banding, group two are animals already coarse And gurpo 3 stranded and tamed. Five animals were chemically contained with xylazine and detomidine, the other 10 being mechanically contained. In the mode B analysis, the values obtained presented a statistical difference between group 1 (one), and the other groups. Blind analysis has shown that LN is more echogenic than adjacent tissues. The difference of these static values was attributed to the age group, and the echogenicity found is due to the ligament being formed by collagen. Thus, it is concluded that ultrasound examination mode B, is a useful tool to identify ligamentous changes in the region studied.
