    Abstract:
    UNLABELLED: HISTORY AND CLINICAL SYMPTOMS: A 58-year-old man was admitted to our hospital with acute chest pain and subfebrile temperatures. Two years ago, endovascular aortic stent-graft placement had been performed for acute type B aortic dissection complicated by malperfusion syndrome. DIAGNOSTIC ASSESSMENT: CT angiography showed a discrete soft-tissue attenuation mass between the aorta and esophagus. The patient developed progressive swallow disorder and esophago-gastro-duodenoscopy demonstrated deep esophageal ulcerations at the level of the implanted aortic stent-graft. Intravenous treatment with broad spectrum antibiotics was started. The FDG-PET/CT scan showed increased FDG uptake and air entrapment in the affected region establishing the diagnosis of aortoesophageal fistula formation. THERAPY AND OUTCOME: Given the generally poor condition of the patient and the high risk of any aggressive surgical intervention, a new limited surgical approach was chosen consisting of open transthoracic esophageal resection, blind closure of the stomach and cervical esophagostomy. A percutaneous endoscopic gastrostomy tube was placed. After three months, esophageal continuity was restored by retrosternal colon interposition. The presented therapeutic management resulted in a full recovery of the patient. CONCLUSION: Aortoesophageal fistula is a rare complication of thoracic aortic stent-graft placement. Patient may present with unspecific symptoms such as fever and rised inflammatory markers, but may also present with massive upper gastrointestinal bleeding. The herein presented limited therapy with esophageal resection represents a promising to the otherwise difficult therapy of aortoesophageal fistula.
