Plain-English summary
An 8-year-old dog with asthma was treated using a surgical procedure called high selective vagotomy, which involves cutting certain nerves in the lungs. Before the treatment, the dog showed increased breathing problems and other asthma symptoms after being exposed to allergens. After the surgery, the dog no longer displayed typical asthma symptoms, and tests showed that its breathing improved significantly. This procedure helped reduce inflammation in the lungs, making it a promising option for managing asthma in dogs.

Abstract
OBJECTIVES: This study evaluated the effect of high selective bilateral vagotomy of hilus pulmonis with video-assisted thoracoscopy on asthma. METHODS: Eight dogs with skin sensitive to Ascaris suum antigens were randomly divided into groups A and B. Asthma was induced by aerosol inhalation of A suum antigens. Respiratory rate and peak airway pressure were significantly increased (P < .05) in both groups. Dynamic compliance was dramatically increased (P < .05) in both groups. Two days later, bilateral vagotomy of hilus pulmonis under thoracoscopic guidance was performed on dogs in group A; dogs in group B underwent bilateral sham vagotomy plus thoracoscopy. Five days after treatment, all dogs had rechallenge with a second aerosol inhalation. RESULTS: Dogs in group A did not show typical asthmatic symptoms, and no significant changes were found in respiratory rate, peak airway pressure, and dynamic compliance (P > .05). Dogs in group B still had typical symptoms, and respiratory rate and peak airway pressure were increased and dynamic compliance decreased significantly (P < .05 for all). Significant differences in respiratory rate, peak airway pressure, and dynamic compliance were observed between groups. Moreover, inflammatory cells in the lungs and bronchoalveolar lavage fluid of group A were dramatically reduced relative to group B (P < .05). There were no significant changes in heart rate and mean arterial pressure after vagotomy, indicating that vagotomy did not affect the cardiac plexus of vagus. CONCLUSIONS: High selective bilateral vagotomy of hilus pulmonis with thoracoscope can effectively control asthma in dogs.
