【 摘 要 】

Grass awns commonly cause respiratory disease in dogs; when located in the trachea or bronchi, they cause severe bronchial inflammation and sepsis. The interplay of cough, bronchoconstriction, and mucus secretion can result in a less effective expulsive cough phase, especially when the causal factor persists. The bronchial exudate could consequently become trapped in the upper respiratory tracts of dogs with bronchial vegetal foreign bodies. We retrospectively reviewed endoscopic findings of the upper respiratory tract in dogs that underwent bronchoscopy in our hospital and correlated these findings with the presence of bronchial grass awns. Muco-purulent exudate in the ventral larynx region, between the vocal cords and laryngeal ventricles, was frequently associated with the presence of bronchial grass awns. This laryngeal finding could be secondary to an altered response to grass awn localization in the bronchi. These results should be carefully considered, particularly in countries where grass awns are commonly found.
