Background Chylothorax is a rare form of pleural effusion that can be associated with both traumatic and non-traumatic causes. Very few patients respond to conservative line of therapy. Thoracic duct ligation is often the treatment of choice in post-surgical patients; however, the optimal treatment of this disease process after traumatic injury remains unclear. Case presentation: We present the case of a 46-year-old woman with thoracic duct injury secondary to decortication for post-pneumonic empyema. Conservative therapy and pleurodesis done twice failed. She developed severe cachexia losing 15 kg in 30 days. She was referred to our center for ligation of thoracic duct. Preoperative lymphangiography located the duct injury in upper part of mediastinum. Computerized tomography scan of chest showed collapse of left lower lobe and thickened left pleura, indicating a significant pericardial effusion. She underwent decortication of left lung, pericardial window, and native pericardial patch repair of thoracic duct. Results and Conclusions: In this unusual and complex case, successful resolution of the chyle leak was achieved with new surgical technique of patch repair. The patient recovered well and was now on a normal diet. She has put on 12 kg in four months. We have avoided late complications of thoracic duct ligation by this technique. This nouvelle technique may be recommended as it is simple and effective. Ligation of thoracic duct carries late complications. Isolating right lung by double lumen tube may cause severe hypoxia as left-sided lung is not expanded as in this case.
