Life- threatening hemothorax due to the inferior pulmonary ligament injury without obvious organ injuries: A case report

Abstract

Traumatic hemothorax is usually associated with obvious organ injuries, such as rib fractures, pulmonary injuries, and other mediastinal injuries. We present a rare case in which a 42-year- old Korean man who fell off of a roof, approximately 3 meters in height, resulting in a life-threatening hemothorax without obvious injuries to the thoracic organs. Chest CT showed a large amount of hemothorax in the right side of the thoracic cavity, and an active bleeding, presumably from the posterior intercostal or the phrenic artery, with a focal aneurysmal change. The emergency thoracotomy was performed to bring the active bleeding under control. The operative findings showed there were only the inferior pulmonary ligament tears, and the active bleeding from it. The postoperative course was uneventful and the patient was discharged without any complications. We should consider the inferior pulmonary ligamental injury as one of causes for traumatic hemothorax.
