초록

5세 수컷 포인터견이 만성 기침 증상으로 내원하였다. 기관지내시경 검사에서 좌측 폐엽으로 분지하는 기관지 내강은 점액농성 삼출물과 함께 70% 이상 허탈된 상태로 관찰되었으며, 주기관 내강에서는 점액성 결절들이 확인되었다. 컴퓨터 단층촬영 검사는 좌측 폐엽으로 주행하는 기관지의 허탈을 재확인하게 하였다. 해당 검사결과들을 근거로, 환자는 만성기관지염과 함께 기관지연화증이 발병한 것으로 진단되었다. 본보는 만성기침을 보이는 대형견에서 기관지연화증을 진단한 증례이며, 기관지내시경검사는 기관지연화증의 발생 유무를 평가할 수 있는 중요한 검사법임을 보여준다.

A 5-year-old male Pointer dog weighing 24 kg was referred because of a chronic cough. The dog was routinely vaccinated and treated monthly with medications to prevent heartworm and endoparasites. Blood analyses revealed no abnormalities. Chest radiographs showed interstitial and bronchial patterns in the caudal lung fields. Bronchoscopic imaging identified a collapse of the left bronchus with a mucopurulent discharge, indicating the onset of bronchomalacia. Computed tomography also showed bronchial collapse and a tapering angle in the left caudal bronchus. This case study describes the diagnosis of bronchomalacia in a Pointer dog with a chronic cough, and suggests that bronchoscopic examination is a valuable tool for identifying of the onset of bronchomalacia in dogs presenting with an uncontrolled cough.
