Aortobronchial fistula.

Aortobronchial fistulas (ABFs) are rare but fatal if left untreated. Hemoptysis is the most common symptom of the patients. ABFs may occur after any thoracic aortic lesions or maneuveurs for these lesions. The treatment of ABF can be surgical or thoracic endovascular aortic repair. Thoracic endovascular aortic repair can be a safe and less invasive procedure for the treatment of ABFs. However, ABFs might occur in much shorter time after thoracic endovascular aortic repair than any other etiologies. The prognoses of patients with ABFs are poor with a high morbidity and mortality. The selection of a suitable endovascular graft and avoidance of postinterventional complications might effectively prevent the occurrence of ABFs.
