“…Migration of extraluminal tracheal ring prostheses has also been previously reported, but no prosthesis migration was observed in our study . Various mortality rates related to respiratory compromise after tracheal ring placement ranging from 9%–26% have been reported . In our study, 13 of the 54 (24%) dogs had died by the time of data collection (median follow‐up time, 30 months).…”

“…Retrospective analysis of CETP placement revealed favorable short‐ and long‐term outcomes in dogs with tracheal collapse. Recent studies have reported that 92%‐95% of dogs survived to discharge after the placement of C‐shaped tracheal rings . We reported that 98% of the dogs survived to discharge except for 1 death due to DIC 16 days after surgery.…”

“…We reported that 98% of the dogs survived to discharge except for 1 death due to DIC 16 days after surgery. In addition, follow‐up surgical procedures are sometimes required after extraluminal ring placement . However, none of the dogs in our study required an additional surgical procedure for continued or recurrent tracheal collapse.…”

“…One prior article reported that the severity of clinical signs improved in all dogs that underwent extraluminal tracheal ring placement and that 65% of the dogs did not require medication postoperatively . In another study in which 26% of the dogs exhibited main‐stem bronchial collapse, persistent coughing was observed in 33% of the dogs after extraluminal ring placement .…”

“…Postoperative complications associated with stent placement include intratracheal granuloma formation, stent fracture or migration, and inflammatory tracheitis . Laryngeal paralysis is particularly problematic with extraluminal prosthesis and ring placement, occurring in 11%‐21% of cases . In addition, perioperative death has been reported in 4%‐19% of cases after extraluminal ring and prosthesis placement.…”

Objective To describe the surgical placement of a continuous extraluminal tracheal prosthesis (CETP) and report the subsequent postoperative clinical outcomes in dogs with tracheal collapse. Study design Retrospective case series. Animals Fifty‐four dogs. Methods Medical records of dogs in which cervical and/or thoracic inlet tracheal collapse was diagnosed and treated by placement of a CETP between 2010 and 2017 were reviewed to evaluate postoperative complications, changes in respiratory function, and survival. Histological examinations of tracheal tissues performed in 2 dogs at 51 and 57 months after surgery were also reviewed. Results Fifty‐three (98%) dogs survived to discharge. Postoperative complications included laryngeal paralysis (1 dog), disseminated intravascular coagulation (1 dog), and recurrent tracheal collapse (2 dogs). None of the dogs exhibited clinical evidence of tracheal necrosis. Preoperative dry, harsh cough resolved in 87% of the dogs after surgery. Goose honking cough was resolved in 25 of 26 (96%) dogs. Median follow‐up time was 30 months (range, 16 days to 76 months). The survival rate at 36 months was 86% (CI: 75%‐96%). On histological examination in 2 dogs, the tracheal tissue surrounding the prosthesis was well preserved and without evidence of chronic inflammation. Conclusion Continuous extraluminal tracheal prosthesis placement in dogs with tracheal collapse resulted in low postoperative complication rates and good long‐term outcomes. Clinical significance Continuous extraluminal tracheal prosthesis placement provides a viable alternative surgical option for managing dogs with tracheal collapse.
