TRACHEAL OBSTRUCTION DUE TO GLOSSAL ENTRAPMENT BY A STRING FOREIGN BODY IN A PEAHEN (PAVO CRISTATUS)

摘要

A female juvenile peahen (Pavo cristatus) presented with acute respiratory distress after the owner observed the bird apparently "choking" the night before presentation. A swelling at the base of the throat was also noted by the owner approximately 2 days prior to the "choking" incident. An air sac breathing tube was placed immediately following presentation and the respiratory rate and effort returned to normal. While performing a physical examination on the patient, a string foreign body was identified and removed from the oral cavity. The string had been wrapped around the base of the tongue, initially resulting in a laceration at the base of the tongue and displacing the glottis caudally, but eventually retroflexed the tongue resulting in occlusion of the glottis. Once the string was transected, the tongue was replaced into normal anatomic position. Three days after presentation, the bird was able to breathe normally with the air sac tube occluded, thus the air sac tube was removed. The lesions under the tongue completely resolved 8 weeks following the initial presentation. Although there have been reports of string foreign bodies in avian species, there are no reports of these foreign bodies causing entrapment of the tongue with subsequent obstruction of the glottis
