Irregularidade morfológica dos anéis traqueais em equinos associada ou não à malformação cervical: Estudo inicial

With the purpose of verifying the existence of irregularities in the tracheal rings of horses and correlating it with the presence of equine cervical vertebral malformation, 45 horses were used, including males and females of different breeds, distributed in two groups, the first being horses with lesions cervical lesion of congenital origin (GI 10 animals) and the second group composed of horses with nom-congenital cervical lesions (GII 35 animals), animals from different parts of Brazil, treated in private practice over a period of 2019-2023 (4 years) . It was observed that both horses without congenital lesions and those with congenital lesions had tracheal rings of different shapes that did not compromise air flow in the animals studied, and also that in all animals with congenital lesions in the cervical vertebrae, they had tracheal rings in the dorsal portion of the tracheal rings a “ridge.” This was an initial study and we believe that further investigation should be carried out.
