Postintubation Tracheal Stenosis in a Blue and Gold Macaw (Ara ararauna) Resolved With Tracheal Resection and Anastomosis

Abstract

A 20-year-old female blue and gold macaw (Ara ararauna) was presented with an acute onset of labored breathing and vocalization changes. Tracheoscopy revealed a stenotic tracheal lesion, which reduced the luminal diameter by approximately 75%. Tracheal resection and anastomosis was performed, and the tracheal lesion was submitted for histopathologic analysis. Postoperative therapy included antibiotic, antifungal, and anti-inflammatory medications. The trachea healed with no major complications. The histologic diagnosis was mild, focal, chronic tracheitis. The cause of the lesion was presumed to be postintubation stenosis on the basis of the normal gross appearance of the external trachea, the location of the lesion, and a recent history of general anesthesia delivered by endotracheal tube.
