Long-term outcome of permanent tracheostomies in dogs: 21 cases (2000-2012).

Abstract

This retrospective study reports long-term outcome, survival, and complications in dogs which received a permanent tracheostomy due to upper airway obstruction. Data were collected from medical records (n = 21) in 2 institutions over a 12-year period. Patients were followed until death, complications, causes of death, and survival times are reported. Major complications were reported in 50% of patients with 20% of patients receiving revision surgery. The most common complications were aspiration pneumonia and need for revision surgery. Median survival time was 328 days with 25% of patients surviving 1321 days or longer. Some (26%) patients died acutely at home at various times after surgery. Permanent tracheostomy is a viable procedure for patients with end stage upper airway obstruction; however, a subpopulation of patients suffers acute death at various times after surgery, which is thought to be due to airway obstruction.
