A 46 year-old man underwent double valve replacement for valve insufficiency due to infective endocarditis. Upon withdrawal from extracorporeal circulation and administration of 8 units of fresh frozen plasma, a large amount of yellow serous secretion was aspirated from the trachea, and rapid and exacerbated oxygenation was observed. We determined that the patient was not congested, based on his hemodynamics; instead, he appeared to have acquired transfusion-related acute lung injury (TRALI). The patient was given a steroid infusion. By the time the patient returned to the intensive care unit, his oxygenation capacity improved and the secretions from his trachea decreased. The patient was weaned off the ventilator on the second post-operative day. Inhaled nitric oxide was very effective in improving oxygenation. We conjectured that TRALI should be recognized as a differential diagnosis for poor oxygenation after withdrawal from extracorporeal circulation.

The frozen elephant trunk technique (FET) for the treatment of acute aortic dissection is associated with more favorable remodeling in the descending aorta compared to those patients without FET, but it may also be associated with postoperative spinal cord injury (SCI) and actually,some postoperative SCI cases after FET are reported. Several risk factors for SCI are known and one of them is due to the occlusion of intercostal arteries from false lumen. A 71-year-old woman underwent total arch replacement with FET, but after surgery, she noticed decreased movement in both lower extremities and was suspected of postoperative paraplegia. She went through cerebrospinal fluid drainage but didn't get better at all. According to the preoperative contrast computed tomography images, seven out of ten intercostal arteries were originating from the false lumen and six of them were occluded after surgery. When most of intercostal arteries are originating from the false lumen and there is no entry inside the descending and abdominal aorta, the intercostal arteries may be occluded due to thrombosis of the false lumen and it may cause spinal cord ischemia after surgery.
