Migration of extraluminal tracheal ring prostheses after tracheoplasty for treatment of tracheal collapse in a dog

Abstract

Migration 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.

Long‐term outcomes of 54 dogs with tracheal collapse treated with a continuous extraluminal tracheal prosthesis

“…However, none of the dogs in our study required an additional surgical procedure for continued or recurrent tracheal collapse. 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 .…”

“…Migration of extraluminal tracheal ring prostheses has also been previously reported, but no prosthesis migration was observed in our study. 19 Various mortality rates related to respiratory compromise after tracheal ring placement ranging from 9%-26% have been reported. 5,10 In our study, 13 of the 54 (24%) dogs had died by the time of data collection (median follow-up time, 30 months).…”

Imaging Diagnosis—use of Radiography, Computed Tomography, and Endoscopy in the Diagnosis of Esophageal Perforation by an Extra‐luminal Tracheal Ring Prosthesis in a Golden Retriever

“…Migration of extraluminal prosthetic cervical tracheal rings has been reported in a Yorkshire terrier, with tracheal perforation diagnosed by tracheobronchoscopy . This case, and the case reported here, both presented approximately 2 years following surgical placement of the prostheses, and both implant failures occurred near the thoracic inlet.…”

“…Extraluminal prosthetic rings can be acquired as commercial premade sizes or they can be fabricated and autoclaved from syringe cases, increasing the options of readily available ring sizes for larger dogs. Known complications of tracheal ring prostheses include laryngeal paralysis, tracheal necrosis, pneumothorax, loosening, breakage, and infection . Intraluminal tracheal stents are commercially available, but for larger patients custom sizes may be required which can delay intervention.…”

“…This case, and the case reported here, both presented approximately 2 years following surgical placement of the prostheses, and both implant failures occurred near the thoracic inlet. The trachea undergoes substantial movement at the thoracic inlet during the respiratory cycle . Chronic movement of this region may result in excess wear or friction on the prosthetic rings and/or sutures that are close to the thoracic inlet.…”
