Plain-English summary
Fifty dogs with tracheal collapse syndrome, a condition that can cause breathing difficulties, underwent a minimally invasive procedure to place a tracheal stent. After the stent was placed, the dogs showed minimal changes in the stent's position and size over time, which suggests that the procedure is generally effective and stable. The stents helped maintain the airway without significant migration or shortening, meaning the dogs were likely able to breathe better after treatment. This study highlights the importance of careful stent placement to ensure the best outcomes for dogs with this condition.

Abstract
BACKGROUND: Intraluminal tracheal stenting is a minimally invasive procedure shown to have variable degrees of success in managing clinical signs associated with tracheal collapse syndrome (CTCS) in dogs. OBJECTIVES: Identify immediate post-stent changes in tracheal diameter, determine the extent of stent migration, and stent shortening after stent placement in the immediate-, short-, and long-term periods, and evaluate inter-observer reliability of radiographic measurements. ANIMALS: Fifty client-owned dogs. METHODS: Retrospective study in which medical records were reviewed in dogs with CTCS treated with an intraluminal tracheal stent. Data collected included signalment, location, and type of collapse, stent diameter and length, and post-stent placement radiographic follow-up times. Radiographs were used to obtain pre-stent tracheal measurements and post-stent placement measurements. RESULTS: Immediate mean percentage change was 5.14%, 5.49%, and 21.64% for cervical, thoracic inlet, and intra-thoracic tracheal diameters, respectively. Ultimate mean follow-up time was 446 days, with mean percentage change of 2.55%, 15.09%, and 8.65% for cervical, thoracic inlet, and intra-thoracic tracheal diameters, respectively. Initial mean stent length was 26.72% higher than nominal length and ultimate long-term tracheal mean stent shortening was only 9.90%. No significant stent migration was identified in the immediate, short-, or long-term periods. Good inter-observer agreement of radiographic measurements was found among observers of variable experience level. CONCLUSIONS AND CLINICAL IMPORTANCE: Use of an intraluminal tracheal stent for CTCS is associated with minimal stent shortening with no clinically relevant stent migration after fluoroscopic placement. Precise stent sizing and placement techniques likely play important roles in avoiding these reported complications.
