短いelephant trunk により生じた遠位弓部大動脈瘤急速拡大の1 例

A 78-year-old female patient was introduced to our hospital with chief complaint of massive hemoptysis. She had a history of total arch replacement using a short elephant trunk for acute Stanford type A aortic dissection 3 years before. A contrast-enhanced computed tomography （CT） revealed kinking of the short elephant trunk and distal aortic arch aneurysm which caused aortobronchial fistula. She was treated by emergency thoracic endovascular aortic repair and long-term administration of antibiotics. Three years later, distal aortic arch aneurysm disappeared by CT and there was no recurrence of hemoptysis. This is the aortic aneurysm was considered to be caused by the short elephant trunk.
