A 66-year-old woman attended our hospital for ascending aortic aneurysm. She was admitted with sudden back pain and acute aortic dissection of Stanford type B was revealed by computed tomography. We performed replacement of the ascending aorta and aortic arch with the frozen elephant trunk technique. The left pleural drainage fluid turned cloudy white after diet initiation on postoperative day 2. We diagnosed chylothorax with biochemical analysis and stopped oral intake completely, but the drainage increased to 3,700ml/day. On postoperative day 8, completely thoracoscopic ligation of thoracic duct was performed. The drainage decreased immediately after the procedure. She could start meals on postoperative day 12 and was discharged on postoperative day 22. We conclude that a completely thoracoscopic ligation of thoracic duct for persistent chylothorax after aortic surgery can lead to early resolution.
