Objective:
To report use of combined cisterna chyli ablation (CCA) and thoracic duct ligation (TDL) for treatment of spontaneously occurring chylothorax in dogs.
Study Design:
Retrospective study.
Animals:
Eight dogs with chylothorax.
Methods:
TDL was performed through a right caudal intercostal thoracotomy and CCA through a left flank paracostal approach or ventral median celiotomy. Long-term outcome (range, 2-48 months; median, 11.5 months) was evaluated by telephone communication with owners.
Results:
Seven dogs were free of clinical signs related to chylothorax at last follow-up (range, 4-48 months; median, 15.5 months). One dog was euthanatized 2 months after surgery because of lack of improvement. No major complications occurred from CCA.
Conclusion:
CCA and TDL resolved chylothorax in most dogs (88%).
Clinical Relevance:
CCA combined with TDL may improve the outcome of chylothorax in dogs.
