Abstract(s)
Na medicina de equídeos, a laminite é a segunda causa mais frequente de mortalidade, ultrapassada
apenas por patologias associadas a episódios de cólica, assumindo assim importância na perspetiva
clínica e ética.
Esta patologia é unanimemente classificada como uma pododermatite asséptica, observada
frequentemente na sequência de processos envolvendo endocrinopatias, endotoxinas e/ ou distúrbios
gastrointestinais, que afeta principalmente as lâminas do aspeto dorsal do dígito. O dano avascular
nestas estruturas e, portanto, à conexão entre a falange distal e a parede do casco pode levar, em
última instância à rotação e afundamento da falange distal dentro da cápsula do casco.
Atualmente, verifica-se a inexistência de consenso no que diz respeito a etiologia, fisiopatologia, ou
mesmo no tratamento desta mesma condição, sendo um dos temas mais controversos da Medicina
Veterinária.
Assim, esta revisão bibliográfica procura atualizar o conhecimento em relação à laminite, nas diferentes
perspetivas da patologia.
In equine medicine, laminitis is the second most frequent cause of mortality, surpassed only by pathologies associated with episodes of colic, thus assuming importance from a clinical and ethical perspective. This pathology is unanimously classified as an aseptic pododermatitis, frequently observed in the sequence of processes involving endocrinopathies, endotoxins and/or gastrointestinal disorders, which mainly affects the laminae of the dorsal aspect of the digit. Avascular damage to these structures, and therefore to the connection between the distal phalanx and the hoof wall, can ultimately lead to rotation and sinking of the distal phalanx within the hoof capsule. Currently, there is no consensus regarding the etiology, pathophysiology, or even the treatment of this condition, which is one of the most controversial topics in Veterinary Medicine. Thus, this bibliographic review seeks to update knowledge regarding laminitis, in the different perspectives of the pathology
