Lung lobe torsion in a dog with lymphangiectasia

Abstract

Pulmonary lobe torsion is characterized by rotation of the pulmonary lobe around its long axis, with torsion of the bronchus and pulmonary vessels at the hilum. This condition is a rare condition in cats and uncommon in dogs. Some of the most common clinical signs that dogs with pulmonary lobe torsion may present are coughing, hemoptysis, dyspnea and tachypnea. Complementary exams such as radiography, ultrasound, bronchoscopy and computed tomography have been used for definitive diagnosis. The objective of this work is to report the case of a 5-year-old Shetland Shepherd dog, who has a history of lymphangiectasia, and was diagnosed with torsion of the left cranial lung lobe. Due to hemoptysis and choking, the animal's hospitalization was recommended. After additional tests, such as ultrasound, radiography and computed tomography, the diagnosis of torsion became definitive. The patient was referred to the surgical service of the Seres Veterinary Center for a lobectomy, which is the surgery of choice for pulmonary lobe torsion. During the surgical procedure, there were no complications and the patient's post-operative period was successful, being discharged 4 days after surgery. The prognosis is good for most animals if surgery is performed.
