Canine Chylothorax Secondary to Esophageal Foreign Body and Stricture.

A 10 yr old female spayed golden retriever was presented to an emergency service for persistent regurgitation. The patient had a history of an aberrant right subclavian artery and a subsequent esophageal stricture with megaesophagus. A thoracic radiograph confirmed the presence of an esophageal foreign body. Point-of-care lung ultrasound confirmed the presence of pleural effusion which was sampled and consistent with chyle. The foreign body was removed endoscopically and the patient was discharged the next day. The patient developed aspiration pneumonia within 1 wk of discharge and was treated on an outpatient basis. Point-of-care lung ultrasound performed 21 days after initial presentation showed resolution of the chylothorax and pneumonia.
