A specific laryngeal finding in dogs with bronchial vegetal foreign bodies: a retrospective study of 63 cases

Abstract

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.

Prostatic Localization of a Migrating Grass Awn Foreign Body in a Dog

“…Vegetal foreign bodies can penetrate through intact skin or natural orifices (external ear canal, nasal sinuses or oral cavity) and subsequently migrate into the body [ 1 , 2 , 3 , 4 , 5 , 6 ]. Migration of the grass awns through the genitourinary tract (urethra, urinary bladder or vagina) has been reported in dogs: an ascending migration through the vagina/urethra or a penetration pathway through the skin/intestinal tract has been suspected [ 7 , 8 , 9 ].…”

“…Migrating grass awns are a frequent cause of foreign body disease in dogs and cats during the spring and summer seasons [ 1 , 2 , 3 , 4 , 5 ]. Migratory characteristics of grass awns, attributable to their fusiform shape and backward-pointing barbs, permit an easy penetration in a unidirectional way until they lodge into a cavity or organ.…”

“…Migratory characteristics of grass awns, attributable to their fusiform shape and backward-pointing barbs, permit an easy penetration in a unidirectional way until they lodge into a cavity or organ. The most common localizations of vegetal foreign bodies are the external ear canal, nasal cavity, interdigital spaces, conjunctiva, thoracic cavity or iliopsoas muscles [ 1 , 2 , 3 , 4 , 5 , 6 ]. Rarely, grass awns can migrate through the genitourinary tract and localize in the urethra, urinary bladder or vagina [ 2 , 7 , 8 , 9 ].…”

Incidence of Bacteremia Consequent to Different Endoscopic Procedures in Dogs: A Preliminary Study

“…Endoscopic procedures in veterinary medicine are performed for both diagnostic (i.e., gastrointestinal and respiratory disease) and therapeutic (such as the removal of foreign bodies) purposes [1][2][3][4][5][6].…”
