Tracheal and bronchial stenting for treatment of airway collapse
Airway collapse (tracheal, bronchial or both) is a very common cause of chronic respiratory signs in dogs. While patient signalment may increase the suspicion of airway collapse in certain cases, for example tracheal collapse in Yorkshire Terriers or left mainstem bronchus collapse in Cavalier King Charles Spaniels with mitral valve disease, airway collapse should be considered as a major differential in any toy or small breed dog presenting with chronic respiratory signs. Clinical signs can include a chronic cough, decreased exercise tolerance, episodes of collapse/syncope, and heat intolerance. These clinical signs can be very worrying for pet owners and can severely affect the quality of life of both the patient and owner. More importantly, life-threatening sequelae can be seen in cases with advanced airway collapse and can include hypoxic episodes and pulmonary hypertension.
At SCVS, we offer both tracheal and bronchial stenting and stock a range of stent sizes so that patients presenting with acute deterioration or as an emergency can be treated without delay. Collapse of the left mainstem bronchus should be considered an important differential in any patient with mitral valve disease presenting with syncopal episodes or other signs such as coughing, which are refractory to cardiac medications or where there is no evidence of pulmonary oedema.
- Stenting can result in significant improvement with regards to clinical signs and quality of life in a patient’s refractory to medical management
- Patients presenting with severe, life-threatening clinical signs can be treated without delay
- Bronchial collapse and stenting should be considered in patients with mitral valve disease and persistent clinical signs which are refractory to management with heart medications.
