[Patient with massive hemothorax due to blunt trauma saved by transcatheter arterial embolization (TAE)].

A 78-year-old man who fell from a step ladder was transported to our hospital by ambulance under the diagnosis of multiple rib fractures and right hemothorax. Since he was in shock on arrival, endotracheal intubation and tube thoracotomy were immediately performed. Though 2 liters of blood was evacuated, persistent hemorrhage was observed, requiring continuous rapid infusion and blood transfusion. Emergency thoracic arteriography revealed active bleeding from a branch of the right internal thoracic artery. Transcatheter arterial embolization (TAE) was performed using vascular embolization coils and porous gelatin particles. These procedures successfully controlled active hemorrhage from the chest. Intrathoracic hematoma was evacuated through the 2nd large chest tube. Chest tubes were removed on the 7th day. He was discharged on the 17th day without any complications.
