Endovascular Repair of Aortobronchial Fistula after Bentall Procedure

Patch aortoplasty and anatomical lung resection in a patient with aortobronchial fistula due to aortic psuedo-aneurysm

Aortobronchial fistula (ABF) is a rare and devastating complication, if left untreated. Its main clinical manifestation is hemoptysis, and there are no defined guidelines for its treatment yet. Herein, we present the case of a 74-year-old male who complained of back pain and hemoptysis. The patient was diagnosed with pseudo-aneurysm and ABF, and he underwent hybrid thoracic endovascular aortic repair. However, hemoptysis recurred. With patch aortoplasty and anatomical lung resection, successful management of ABF was achieved, with no relapse for 5 years.

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.
