Achados clínicos, radiográficos, ultrassonográficos e de toracoscopia em um caso de torção de lobo pulmonar crônica em cão

Abstract

Non-cardiac thoracic ultrasound is an imaging diagnostic modality complementary to chest radiography, which makes it possible to distinguish between the structures belonging to the thoracic cavity. Thoracoscopy is a minimally invasive procedure performed to inspect the same structures of the thoracic cavity, frequently used for the diagnosis and treatment of diseases. Knowing this, pulmonary lobe torsion may be related to partial or complete torsion of the lung lobes, causing narrowing and obstruction of the main bronchi. The objective of the present work was to highlight the clinical, ultrasonographic, radiographic and thorocoscopy findings for the diagnosis of pulmonary lobe torsion in a dog through a case report. A middle-aged male pug dog presented with a cough, which gradually worsened over the last three months. Using the ultrasound examination, it was possible to identify an area of pulmonary consolidation, compatible with the alveolar pattern identified in the radiographic examination. The thoracoscopy technique was performed, where an area of torsion in the lung lobe was found, with a lung lobectomy procedure performed and the material sent for biopsy. Confirming through histopathological examination that it was a torsion of the pulmonary lobe. The postoperative period was favorable, even though the animal had a poor survival prognosis. We can conclude from this report that the approach applied was assertive in diagnosing pulmonary lobe torsion.
