AbstractTransfusion-related acute lung injury (TRALI) is a serious complication of blood transfusion, which is characterized by the acute onset of non-cardiogenic pulmonary edema and hypoxemia following the administration of blood products. We report a case of possible TRALI during thoracic endovascular aortic repair (TEVAR). The patient was a 61-year-old man (161 cm in height, 61 kg in weight) who underwent TEVAR for the traumatic injury at the isthmus of aorta. He had a light preexisting lung injury. About 1 hour following the blood transfusion (red cell concentrates, fresh-frozen plasma, and platelet concentrates), he suddenly fell into severe hypoxemia (PaO2 52 mmHg in FI(O2) of 1.0). The radiographic examination showed pulmonary edema, i. e., bilateral infiltrates and pleural effusion. No evidence of circulatory overload was observed. Anti-human leukocyte antigen antibodies in his serum and anti-granulocyte antibodies in the donor blood were detected. In spite of intensive care including artificial ventilation with positive end-expiratory pressure and the administration of methylprednisolone and a granulocyte elastase inhibitor, he died of exacerbated hypoxemia and hypotension 4 hours after the onset of acute lung injury. Of great importance is being aware of an unexpected occurrence of TRALI during and soon after blood transfusion.
