title: Anaesthetic and surgical management of an intra-tracheal mass in a cat.
abstract: An 11-year-old, 7 kg male neutered domestic shorthair cat, presented to the University Veterinary Hospital (UVH) for investigation of chronic tachypnoea and dyspnoea. Radiographs, bronchoscopy and computerised tomography (CT) demonstrated an intra-tracheal mass measuring 13 mm × 5 mm × 6 mm arising from the right wall of the caudal trachea immediately cranial to the carina. Due to size and position, debulking and subsequent cryosurgery were attempted to minimise the amount of tissue removed and prevent recurrence. A combination of anaesthetic techniques was required to allow cryotherapy, with the trachea open whilst maintaining adequate ventilation. This case report demonstrates that cryotherapy in conjunction with anaesthetic planning, can achieve a positive outcome for the cat.
