Traumatic injury of the thoracic duct

Injuries to the thoracic duct are infrequent but may become life-threatening when chylous leakage persists. This report describes 6 patients with such injuries in whom the leakage resolved spontaneously in one, was corrected using microsurgical lymphatic repair or lymphatic-venous anastomosis in two, successfully treated either by ligation of the thoracic duct or insertion of a peritoneovenous shunt in two, and was eventually controlled after bilateral pleurodesis and thoracic duct ligation by insertion of a peritoneo-venous shunt in one. Conventional lymphography is superior to lymphoscintigraphy and is usually required to document disruption of the thoracic duct.
