RESUMO
OBJECTIVE: To outline the clinical findings, surgical management, complications, and outcomes in a case of intrathoracic, traumatic, tracheal avulsion. CASE SUMMARY: A 2-year-old domestic shorthair cat presented with respiratory distress 18 days after a motor vehicle accident. A tracheal avulsion was diagnosed and treated by surgical anastomosis. The initial anastomosis failed. The subsequent tracheoscopic-assisted tracheal anastomosis was successful. The cat had no further episodes of respiratory distress following the second surgery in a 9-month follow-up period. UNIQUE INFORMATION PROVIDED: This communication describes a complication of intrathoracic, traumatic, tracheal avulsion repair that has not previously been described and the use of tracheoscopy during the subsequent surgical procedure to ensure accurate suture placement.

OBJECTIVES: The main purpose of this study was to design, manufacture and implant a customized three-dimensional (3D) printed, intervertebral spacer to treat disc-associated cervical spondylomyelopathy (DACSM) in dogs. This study also used advanced imaging to assess implant movement, subsidence and interbody fusion. ANIMALS: Two client-owned dogs with DACSM. METHOD: Customized interbody devices were designed and 3D printed in titanium alloy. The devices were implanted in dogs diagnosed with DACSM. The dogs were evaluated at time points 0, 2 and 6 months to determine clinical outcome, degree of interbody fusion, implant migration and subsidence. RESULTS: Progressive fusion was noted across the affected intervertebral space by 6 months. Implants mildly shifted cranially in the 2-month interim. There was no subsidence of the intervertebral device through the vertebral end plates in dog 1 and minimal in dog 2 (â¼0.5 mm). Clinically, the neurological status improved in both dogs. CONCLUSIONS: The customized interbody devices restored the intervertebral space and resulted in a degree of interbody fusion and resolution of clinical signs. CLINICAL SIGNIFICANCE: This report illustrates preliminary outcomes of DACSM treated with a customized, end plate conforming, intervertebral device. Collaboration between clinicians and engineers with advanced manufacturing technologies can provide a cutting-edge standard of care for patients suffering from DACSM.
