RESUMOForam avaliadas 386 radiografias da articulação coxofemoral, sendo 220 de cães da raça Pastor Alemão, 112 machos e 108 fêmeas, e 166 da raça Labrador Retriever, 69 machos e 97 fêmeas. As radiografias foram classificadas segundo o grau de displasia coxofemoral (DCF), e foram mensurados o ângulo de inclinação, o ângulo de Norberg, o índice cortical e o percentual de cobertura da cabeça femoral de ambos os lados. As variáveis foram associadas mediante análise estatística multivariada de componentes principais. As variáveis índice cortical e ângulo de inclinação foram inversamente associadas. A raça Pastor Alemão apresentou valores de índice cortical e graus de DCF mais baixos em relação à raça Labrador Retriever. Maior ângulo de inclinação foi associado a menor ângulo de Norberg e menor percentual de cobertura. Animais mais velhos apresentaram menor ângulo de Norberg, menor porcentagem de cobertura e maior grau de DCF. Nas fêmeas, foram observados menor porcentagem de cobertura, menor ângulo de Norberg e maior grau de DCF. Pode-se concluir que o ângulo de inclinação e o índice cortical não demonstraram associação com a DCF.Palavras-chave: cão, displasia coxofemoral, ângulo de Norberg, índice cortical, ângulo de inclinação, percentual de cobertura
ABSTRACT
A total of 386 radiographs of the pelvis were evaluated, being 220 of German Shepherd dogs (112 males and 108 females) and 166 of Labrador Retrievers (69 males and 97 females). The radiographs were degree classified regarding the of hip dysplasia (DHD). The Norberg and inclination angles, the corticomedullary index, and the percentage coverage of the femoral head were measured and associated using multivariate statistical technique (principal component analysis). The cortico-medullary index and the inclination angle were inversely associated. The results indicated that German Shepherd
Symptomatic cavernous malformations in the ventral region of the pons are difficult to access surgically. The authors present a case of a 46-year-old woman with a 10-year history of sudden and transitory diplopia and right hemiparesis, followed by five more episodes of mild right hemiparesis. Brain MRI showed a 2.6-cm cavernous malformation in the pons with an exophytic portion in the prepontine cistern. The patient underwent an endoscopic endonasal transclival approach for a complete resection of the lesion. CSF leak was noted and corrected on the sixth postoperative day. The patient progressed with complete motor deficit recovery.The video can be found here: https://youtu.be/ePgpyij2Wpo.
