Thoracic duct ligation is a surgical procedure that involves the deliberate closure or ligation of the thoracic duct, a major lymphatic vessel in the human body. The thoracic duct plays a crucial role in the lymphatic system, which is responsible for transporting lymphatic fluid (lymph) and immune cells throughout the body.
Thoracic duct ligation is generally considered when conservative treatments have not been successful in managing chylothorax. The surgery aims to prevent further leakage of chyle into the pleural space and promote the resolution of chylothorax.
