    Abstract:
    Aortoesophageal fistula (AEF) is a rare cause of upper gastrointestinal bleeding that often receives little attention in the emergency department. The classic presentation includes the Chiari triad of central chest pain, sentinel arterial bleeding, and subsequent evacuation after an asymptomatic period. For patients suspected of having AEF, a CT scan with IV contrast is the preferred diagnostic modality. In our patient, the presence of an aortic wall outpouching, ectopic gas, periaortic fat stranding, and leukocytosis, even in the absence of fever and positive blood culture, suggested mycotic aneurysm with AEF. The unique aspect of this case report is the occurrence of AEF as a rare complication of endoscopic procedures, which should be considered. Treatment options for AEF include surgery and thoracic endovascular aortic repair (TEVAR). TEVAR is a good option for stabilizing the patient's condition and reducing mortality in the short term. Once the patient's condition is suitable for AEF repair surgery, surgical intervention can be performed.
