Unilateralização da Cartilagem Aritenoide em Cão da Raça Dogue Alemão com Paralisia de Laringe
Notice bibliographique
Résumé
Background: Laryngeal paralysis is a disorder that affects the movement of the arytenoid cartilages, creating an obstacle to the passage of air during inspiration. The disease is progressive and clinical signs are associated with upper airway obstruction. Diagnosis occurs through observation of laryngeal movements, and it is important to rule out concomitant diseases. In severely affected animals, surgery is recommended to alleviate clinical signs and improve quality of life. The aim of this report is to report a case of idiopathic laryngeal paralysis in a dog submitted to arytenoid unilateralization to clear the upper airways and evaluate the effectiveness of the technique. Case: A five-year-old male canine was treated at the Hospital de Clínicas Veterinárias of the Federal University of Rio Grande do Sul (HCV-UFRGS) with severe respiratory distress and respiratory stridor. The animal was taken directly to the emergency room, where it was promptly submitted to oxygen therapy with the aid of a mask, was medicated with nalbuphine hydrochloride 0.3 mg/kg intramuscularly and venous access was performed. After stabilization, complete blood count, biochemical profile, blood gas analysis and chest X-ray were requested. In the anamnesis, the tutor reported that the dog showed signs of fatigue with exercise intolerance, coughing similar to choking, breathing difficulties and noisy breathing, especially on hotter days and in situations of exertion, stress or euphoria. He mentioned that the signs were progressive, having started two months ago and that they were more frequent and lasting. The patient was diagnosed with laryngeal paralysis through transoral laryngoscopy and referred to surgery. The improvement in the breathing pattern and the absence of post-surgical complications resulted in the patient being discharged 6 days after hospitalization. Discussion: When the origin of laryngeal paralysis is undefined, the acquired form may be a consequence of generalized polyneuropathy, polymyopathy, neoplasia, endocrinopathy, iatrogenic or idiopathic injury. The patient under study did not present clinical signs or history of disease, therefore, the case was classified as idiopathic in origin. LP of unknown cause is the most common and affects mainly middle-aged to elderly males, large or giant breeds. The disease is often described in Labrador Retriever dogs, but it can affect other breeds such as Great Dane. This information corroborates the profile of the patient in this study. Although oral laryngoscopy is the recommended method for confirming the diagnosis in dogs with characteristic signs of LP, the diagnosis can also be obtained by transnasal laryngoscopy or echolaryngography, however, previous studies have shown that the sensitivity and specificity of diagnosis through echoaryngography is inferior to transnasal laryngoscopy, suggesting that direct visualization of the larynx is better to indirect visualization. Dogs with signs of moderate to severe respiratory distress or whose quality of life is affected as a result of LP are candidates for surgical treatment, as in this case, in which the patient had exercise intolerance and severe respiratory distress. The arytenoid unilateralization procedure proved to be effective in improving the quality of life of the patient under study, achieving excellent postoperative results and approval by the tutor. In this case, transoral laryngoscopy was essential to determine the diagnosis and establish the treatment. Although the goal of improving quality of life has been achieved without major complications, the animal must receive long-term follow-up due to a possible correlation with generalized polyneuropathy and long-term complications. Keywords: stridor, aspiration pneumonia, upper airway obstruction, laryngoscopy.
