Abstract
CASE SUMMARY: A 10-year-old neutered male domestic shorthair cat was evaluated because of signs of stertorous breathing and reverse sneezing of 8 months' duration. A CT scan performed 1 week before evaluation indicated nasopharyngeal stenosis or collapse. Increased respiratory effort, stertorous breathing, coughing, reverse sneezing, bilateral black ocular discharge and mucoid left nasal discharge were noted. Rhinoscopy suggested possible nasopharyngeal stenosis. Balloon dilation was attempted but unsuccessful. Ventral rhinotomy was performed the following day using a spring-loaded mouth gag to access the surgical site. After rhinotomy, the patient had neurologic signs attributed to global cerebral ischemia that progressed to respiratory arrest, subsequently resulting in euthanasia. RELEVANCE AND NOVEL INFORMATION: While ischemic brain injury has been associated with the use of a spring-loaded mouth gag in cats, to our knowledge this is the first reported instance where use resulted in respiratory arrest culminating in euthanasia.
