[Transfusion-related acute lung injury: a case report].

We report a patient who was suspected of transfusion-related acute lung injury. A 60-year-old man underwent emergency thoracotomy and hemostasis after pneumonectomy. The SpO2, decreased abruptly to 66% 90 minutes after transfusion of packed red blood cells and fresh frozen plasma. He was ventilated with 100% oxygen. The SPO2 returned to 100% in 3 minutes. Postoperative chest radiography showed diffuse pulmonary infiltrates. The pulmonary edema improved in 12 hours with mechanical ventilation.
