Procedure
This minimally invasive procedure is performed under anesthesia. The trachea is measured using CT or radiography, and then visualized using a flexible airway scope. Under fluoroscopic guidance, a metallic stent is placed in the trachea. This holds the trachea open and permits air to move down to the lungs. This stent can be removed within the first day or two, but soon becomes incorporated and fixed within the trachea.
Indications to Take this Procedure
Tracheal collapse or deformity. Stenting is generally reserved for dogs with persistent coughing or difficulty breathing despite diligent medical care.
Patient Eligibility
Any dog, any size.
Cost
$5000-$6000, depending on imaging modality used. Pre-operative evaluation (e.g., labwork, echocardiogram) and/or supportive care (oxygen therapy) may be necessary and will incur additional costs.
Length of Stay
24 hours post-procedure to monitor for coughing.
Complications
Long term complications include stent fracture and/or occlusion with granulation tissue. Chronic or recurrent airway infection may also occur.
Anticipated Outcome
This is a salvage procedure for patients with severe tracheal disease. Most dogs are markedly improved following stent placement, and survival times average 2-3 years. On-going medical therapy is necessary to prevent or manage coughing and/or infection.
