ABSTRACT

Foram utilizados 30 cães neurologicamente saudáveis e realizadas radiografias da coluna cervical, sendo mensurada a menor distância atlantoaxial dorsal e outros parâmetros anatômicos vertebrais. Esses dados foram avaliados por meio do coeficiente de correlação de Pearson. Após detecção do melhor parâmetro de correlação, utilizou-se a fórmula de coeficiente de correlação dimensional (CCD). Na segunda etapa desta pesquisa, foram utilizadas imagens radiográficas de 33 cães com subluxação atlantoaxial (SAA) e aplicou-se a fórmula CCD. Todas as imagens atlantoaxiais normais e subluxadas foram distribuídas aleatoriamente e submetidas à análise subjetiva. Observou-se que o parâmetro anatômico de maior correlação foi o comprimento do processo espinhoso do áxis, obtendo-se valor de índice médio de 0,056 e desvio-padrão de 0,019. O valor de índice médio obtido em cães com SAA foi de 0,287, e o desvio-padrão de 0,123. A análise subjetiva revelou acerto de 88,89% a 95,24%, enquanto a avaliação por meio da fórmula CCD demonstrou ser 100% eficiente no diagnóstico da SAA. Sugeriu-se a utilização da fórmula CCD para obtenção do índice de normalidade da distância atlantoaxial com valor de normalidade médio de 0,056 e limite máximo de 0,098, sendo esse índice eficaz no diagnóstico da subluxação entre o atlas e o áxis.(AU)


Thirty healthy dogs had their cervical spines radiographed, and the dorsal atlantoaxial distance and others vertebral anatomical parameters were measured. These data were assessed using the Pearson correlation coefficient. After detection of the best correlation parameter, we used the dimensional correlation coefficient of formula (CCD). In the second stage of the study, radiographs of the 33 dogs with atlantoaxial subluxation (SAA) were used. In each radiographic image, the CCD formula was applied. All normal and subluxation radiographic images were randomized, and submitted to subjective analysis. It was observed that the anatomical parameter with the highest correlation is the length of the spinous process of the axis, obtaining a mean value of 0.056 index and 0.019 standard deviation. Index mean value obtained in dogs with the disease of 0.287 and standard deviation of 0.123. The subjective analysis revealed 88.89% to 95.24% agreement, while the result obtained by the CCD formula was shown to be 100% effective in the diagnosis of SAA. We suggest the use of the CCD formula to obtain the index of normality of the atlantoaxial distance with a mean value of 0.056 and maximum of 0.098, and it is concluded that the index is highly effective in the diagnosis of subluxation between the atlas and the axis.(AU)

ABSTRACT

A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats.

ABSTRACT

Relata-se o caso de um gato que apresentava persistência do uraco, cujos principais sinais clínicos, iniciados apenas aos cinco meses de idade foram micção através da cicatriz umbilical, hiperemia da área circunvizinha e presença de uma fístula no centro do umbigo. A afecção foi diagnosticada mediante exames clínico, laboratorial, ultra-sonográfico e radiográfico, especialmente pela cistografia


It is reported a case of a cat presenting persistence of the urachal. The symptoms only began at five months of age. The diagnosis was confirmed by the clinical, laboratorial, ultrasonographic and radiographic exams, especially by the cystography
