【 摘 要 】

Aortobronchial fistula (ABF) induced by an infected pseudoaneurysm of the thoracic aorta is a life-threatening condition. As surgical treatment is associated with significant mortality and morbidity, thoracic endovascular aneurysm repair (TEVAR) may be an alternative for the treatment of ABF. However, the long-term durability of this intervention is largely unknown and the recurrence of ABF is a potential complication. We experienced a case of recurrent ABF after stent grafting as an early procedure for an infected pseudoaneurysm of the thoracic aorta. Remnant ABF, bronchial and/or aortic wall erosion, vasa vasorum connected with ABF, and recurrent local inflammation of the thin aortic wall around ABF might cause recurrent hemoptysis. As a result, we suggest that TEVAR should be considered as a bridge therapy for the initial treatment of ABF resulting from an infected pseudoaneurysm, and that several options, such as second-stage surgery, should be considered to prevent the recurrence of ABF.
