Abstract
Traumatic chylothorax after blunt chest trauma alone is considered rare. Our patient was a 27-year-old female who was in a motorcycle accident and sustained blunt thoracic and traumatic thoracic aortic injuries with T1-T2 vertebral subluxation. She underwent thoracic endovascular aortic repair from T4 to T9 without any thoracic or spinal surgery. On postoperative day 7, the drainage from her left chest turned into a milky-white fluid indicative of chyle leakage. The patient was treated conservatively for 2 weeks and then the chest drain was safely removed. The results show that traumatic chylothorax can be successfully managed with conservative treatment.
