Tracheal Stenosis Managed with Silicone T-Tube Placement in a Cat

Abstract

Tracheal stenosis in cats generally has a poor prognosis. A 11-years-old female domestic short hair cat was admitted for tracheal stenosis with persistent stridor. Laryngotracheoscopy revealed mucosal thickening in the cervical trachea. Biopsy and brushing were underwent, following a silicone T-tube insertion into the stenotic trachea through a tracheotomy. Immediately, stridor was improved. Microscopic examination of the biopsy specimen disclosed chronic inflammation. The cat had been asymptomatic with medical therapy for 120 days until the T-tube extubation, and survived 480 days without relapse after the extubation.
