Abstract

Le collapsus trachéal est couramment rencontré comme cause de toux et est causé par l’affaiblissement du support cartilagineux des grandes voies respiratoires. L’objectif de cette étude est de mesurer le taux de prévalence du collapsus trachéal canin, de donner les indicateurs de risque et enfin, d’évaluer et de typer les radiographies car elles sont le principal moyen de confirmation du collapsus trachéal. Cette étude rapporte les résultats obtenus à propos de l’investigation descriptive sur 21 cas de collapsus trachéal diagnostiqués chez 5701 chiens admis en consultation à la clinique de l’École Nationale de Médecine Vétérinaire de Sidi Thabet en service de médecine interne des équidés et des carnivores depuis 7 ans. Les résultats ont montré que la prévalence du collapsus trachéal est assez faible (0,36 %, IC 95 %) et soulignent l’importance du signalement lors de l’évaluation des chiens présentant un collapsus trachéal. Cette étude a identifié deux indicateurs de risque de la maladie, les chiens gériatriques (>6ans) (p0,001) étaient plus susceptibles d’être touchés (OR=44) que les chiens plus jeunes (6ans). Il apparaît également que les chiens caniches représentent 62% des chiens atteints, les chiens de petites races étant les plus touchés par le collapsus trachéal (85%). (p 0,001). Il s’agit de la première étude connue décrivant le collapsus trachéal canin en Tunisie.

Résumé :

Tracheal collapse is a common cause of cough and is caused by weakening of artilage support for the large airways The purpose of this study is to measure the prevalence rate of tracheal collapse in dogs, investigate risk indicators, and finally evaluate and type radiographs as they are the main means of confirming tracheal collapse. This study reports the results of a descriptive study of 21 cases of tracheal collapse diagnosed in 5701 dogs treated for 7 years at the clinic of the National School of Veterinary Medicine of Sidi Thabet (Tunisia) in the Department of Equine and Carnivore Internal Medicine. The results show that the prevalence of tracheal collapse in dogs is quite low: 0.36%, CI 95%. The results of this study highlight the importance of signaling in the evaluation of dogs with tracheal collapse. Two risk indicators for the condition were identified in this study. Geriatric dogs (> 6 years) (p 0.001) were more commonly affected compared to younger dogs ( 6 years) (OR =44). It also appears that poodle dogs account for 62% of affected dogs, small breed dogs are most commonly affected by tracheal collapse (85%). (p 0.001). This is the first known study describing tracheal collapse in dogs in Tunisia. The retrospective design of this study further limits the results of this investigation
