Transfusion-Related Acute Lung Injury Type I Immediately after Open Surgical Repair for Abdominal Aortic Aneurysm.

A 68-year-old man underwent open surgical repair for an abdominal aortic aneurysm. The intraoperative period had no adverse events until postoperative extubation. His SpO2 rapidly dropped, and severe acute lung edema developed. He had cardiopulmonary arrest. Cardiogenic pulmonary edema and other diseases were ruled out. He was finally diagnosed with transfusion-related acute lung injury (TRALI) type I. Intensive care with ventilator management and continuous adrenaline administration was provided. His condition gradually improved, and he was discharged without any sequelae. Surgical cases requiring blood transfusion should be carefully monitored, and prompt action should be taken when TRALI occurs.
