Positive pressure ventilation and permanent tracheostomy to treat suspected negative pressure pulmonary edema related to cervical oncocytoma in a dog

Abstract

A 10-year-old spayed female Spitz was referred to our center for the confirmation and treatment of a recurrent cervical mass, which was previously diagnosed as oncocytoma. Pulmonary edema was identified by chest radiographic imaging. During the examination, the dog developed severe respiratory distress. After intubation, positive pressure ventilation and positive end-expiratory pressure were employed, and the pulmonary consolidation was resolved within two days. Therefore, negative pressure pulmonary edema related to the cervical mass was suspected. Permanent tracheostomy was performed to reduce upper airway narrowing caused by the unresectable mass on day 3. The dog was discharged on day 13 and survived for 312 days after surgery.
