INTRODUCTION
Aortoesophageal fistula (AEF) is a relatively rare condition that is often life-threatening.1-3 Secondary AEF, a complication of surgery in the posterior mediastinum such as open repair, thoracic endovascular aortic repair (TEVAR), and esophageal surgery, can be more critical than primary AEF, and the management can be more challenging because of the presence of adhesion in the pleural space and the poor general status of patients. The number of secondary AEF is increasing due to increase in the number of TEVAR. Although there have been few studies comparing post TEVAR and post graft replacement secondary AEF cases, 4,5 secondary AEF after TEVAR can be more critical than secondary AEF after graft replacement.
