Treatment of Postsurgical Chylothorax

Patients with chylous chest tube outputs of 1,100 mL or more in 24 hours postoperatively should be considered for intervention. Intention-to-treat analysis shows surgical duct ligation is more effective than thoracic duct embolization, with the ability to cannulate the cisterna chyli being the limiting factor. Lymphangiography may help determine which patients are better treated with ligation or embolization.
