If conservative management fails in chylothorax, which intervention is used?

• A. VATS thoracic duct ligation or IR-guided thoracic duct embolization
• B. Pleurodesis with talc
• C. Lobectomy
• D. Pneumonectomy

Answer: (A)

When chylothorax continues despite initial conservative measures, the next step is to interrupt the source of the leak by targeting the thoracic duct. This is achieved with thoracic duct ligation, usually done through video-assisted thoracoscopic surgery (VATS), or with thoracic duct embolization performed by interventional radiology. Both approaches directly seal or occlude the duct to stop chyle from entering the pleural space, offering a definitive resolution in many cases. Pleurodesis with talc can help prevent fluid re-accumulation in some chronic or refractory cases, but it doesn’t fix the leak itself and is less definitive as a primary next step. Lobectomy or pneumonectomy do not address the lymphatic leak and are not used to treat chylothorax.
