    Abstract:
    Aortoesophageal fistula is rare but fatal if untreated. Open thoracic surgery is associated with high operative mortality and morbidity. We report a case of a 77-year-old man who, treated with thoracic endovascular aortic repair (TEVAR) for descending thoracic aneurysm in another center, after an acute episode of hematemesis and melena was referred to our center. The total body computed tomography scan showed the presence of reperfusion of the descending thoracic aneurysm sac (8.8 cm in diameter) in the proximal and distal TEVAR landing zone (endoleak type I) without clear signs of fistulous tract with the esophageal lumen. The patient underwent new TEVAR inside previous implantation with proximal landing very close to left subclavian artery and distal landing just above celiac trunk. For the presence of a tracheoesophageal fistula, an esophageal endoprosthesis was implanted few days later, and a jejunostomy was performed. At 30 days, patient was in good general condition, but he died at 3 months' follow-up. Aortoesophageal fistula is a rare and usually fatal condition; early recognition and TEVAR treatment prevent immediate exsanguination in patients, but after deployment of the endograft, most patients are at risk for infectious complications. Cessation of bleeding and restoration of circulation is of paramount urgency, but infectious diseases and esophageal repair remain open problems.
