Cervicothoracic radiography revealed a soft tissue opacity within the lumen of the cervical portion of the trachea at approximately the level of the fifth cervical vertebra. Tracheobronchoscopy revealed 2 prosthetic rings protruding into the tracheal lumen.<\/jats:p>\n<jats:p><jats:bold>Treatment and Outcome<\/jats:bold>\u2014The dog was anesthetized, and the 2 protruding tracheal ring prostheses were removed via separate tracheotomies. Tracheoscopy was performed after surgery, and a third prosthetic ring that was found freely floating within the tracheal lumen was removed with an endoscopic grasping forceps. The dog recovered without complications. Dyspnea resolved within the first 2 weeks after surgery. Follow-up examination performed 6 months after surgery revealed that the dog was breathing normally, with no dyspnea or coughing reported by the owner.<\/jats:p>\n<jats:p><jats:bold>Clinical Relevance<\/jats:bold>\u2014Migration of extraluminal tracheal ring prostheses should be included in the differential diagnoses for any dog with dyspnea or persistent coughing after surgical correction of cervical tracheal collapse. Surgical removal of the protruding prosthetic rings, without provision of additional tracheal support, was a viable treatment option in this case.<\/jats:p>","DOI":"10.2460\/javma.243.1.102","type":"journal-article","created":{"date-parts":[[2013,6,20]],"date-time":"2013-06-20T16:04:51Z","timestamp":1371744291000},"page":"102-104","source":"Crossref","is-referenced-by-count":6,"title":["Migration
