We report a case of 10-year-old woman with aortitis syndrome who had a graft dehiscence at the site of proximal anastomosis 8 months after aortic root replacement. Because she suffered severe chest compression and ST depression was demonstrated on 12 lead ECG, she was admitted on a suspicion of vasospasmic angina. However, transesophageal echocardiogram and CT showed an echo-free space around the previous operated aortic composite graft, so we concluded that a proximal graft dehiscence and bleeding around it was the cause of her severely deteriorated circulatory condition, and emergency redo aortic replacement was planned. After deep hypothermic circulatory arrest was accomplished, selective cerebral perfusion was performed following re-sternotomy. Previous composite graft was detached at the site of proximal anastomosis, and the aortic annulus was friable and edematous. Redo aortic replacement successful. Laboratory findings revealed uncontrollable aortitis syndrome as the etiologic factor of graft dehiscence. Postoperatively, she was complicated with cerebral infarction due to a stuck valve. She was discharged at 56 postoperative day.
