Torção espontânea de lobo pulmonar cranial esquerdo em cadela de dezessete anos

Abstract

Lung lobe torsion is one of the causes of dyspnea and respiratory changes in dogs. Twisting of the bronchovascular hilum on its axis, leads to loss of function and metabolic and physiological changes that result in necrosis of the affected lobe. Atelectasis, venous congestion, and pleural effusion secondary to the lobe torsion are responsible for the clinical signs. Chest radiographs or CT scan are used to confirm the diagnosis. In rare cases confirmation is done by exploratory thoracotomy. The prognosis is good after removal of the affected lung lobe. We report a case of left cranial lung lobe torsion in a 17-year-old bitch, successfully treated by lung lobectomy.
