註釋Objective: To evaluate the complications and outcomes of video assisted thoracoscopic (VATS) treatment of chylothorax in cats.Study Design: Multi-institutional retrospective study.Animals: Fifteen client-owned cats.Methods: Medical records of cats undergoing thoracoscopic thoracic duct ligation (TDL) for treatment of idiopathic chylothorax were reviewed. Cats undergoing additional procedures including thoracoscopic pericardectomy and/or laparoscopic cisterna chyli ablation were included. Follow up was obtained through communication with the referring veterinarian or owner.Results: Fifteen cats were included in the study. Conversion from a thoracoscopic to open approach was necessary in 2/15 (13%) of thoracic duct ligations and 1/11 (9%) of pericardectomies. The most common post operative complication was persistent pleural effusion in 5 cats (33%). Four of 15 cats (27%) died or were euthanized prior to hospital discharge following surgery. Recurrence of chylous effusion occurred in 1/6 (17%) of cats that sustained resolution of the effusion with surgery. The overall mortality attributed to chylothorax within the study period was 47%.Conclusion: Thoracoscopic treatment of idiopathic chylothorax resulted in a low incidence of intraoperative complications or conversion in the study population, however mortality related to feline idiopathic chylothorax remained high despite a minimally invasive surgical approach. Clinical Significance: While VATS treatment of idiopathic chylothorax is technically feasible, further consideration of the underlying pathology and current treatment algorithm is needed to improve outcomes as this remains a frustrating disease to treat in the feline population.
