Abstract

A 9-year old, castrated male Pekingese dog weighing 6.9 kg was referred with one week history of dyspnea, depression, yellow vomiting and abdominal distension. Refractory right lung field opacity was diagnosed as spontaneous right cranial lung lobe torsion (LLT) with collapsed middle lobe on the computed tomography. Four days after diagnosis, right fourth intercostal thoracotomy was performed under propofol-remifentanil based total intravenous anesthesia (TIVA). Right cranial and middle lung lobes were twisted together in a clockwise direction. ENDOPATH-ETS-FLEX-45, an articulating endoscopic linear cutting stapler was applied at the hilus and there were no complications after resection. The patient recovered favorably and has been doing well up to one year follow up. Lung lobe torsion is an uncommon condition in small breed dogs, this case report suggests serial lung lobe torsion of cranial lobe followed by middle lobe in small breed dog, and immediately after diagnosis surgical intervention is beneficial to prevent progression of LLT. Furthermore, using self cutting stapling device and TIVA technique will be helpful for lung lobectomy in dogs.

9년령의 중성화 수컷, 6.9kg의 케피니즈견이1주일간 지속된 호흡곤란, 침울, 황색 구토와 복부 팽만을 주증으로 내원하였다. 치료에 반응을 보이지 않는 폐야의 밀도 항진은 CT 촬영에서 우폐중엽의 허탈을 동반한 우폐전엽의 염전으로 진단되었다. 진단으로부터 4일째, 프로포폴과 레미펜타닐을 이용한 전정맥 마취하에 우4늑간 개흉술을 실시하였을 때 우폐중엽과 우폐전엽은 함께 시계방향으로 꼬여있었다. 자가 절단식 선형 복강경 스테플러(ENDOPATHETS-FLEX-45)를 우폐전엽과 우폐중엽의 폐문부에 적용하였고, 폐엽절제 후 복합증은 나타나지 않았다. 본 증례는 우폐전엽의 염전을 따라 연속적으로 우중엽의 염전이 진행된 경우로, 소동물에서 흔하지 않은 폐염전은 진단 후 즉각적 수술 처치가 필요함을 지시하며, 덧붙여 개에서 폐엽 절제시 자가 절단식 스테플러의 적용과 전정맥 마취의 유용성을 나타낸다.
