Abstract
Aortoesophageal fistula (AEF) is an uncommon complication of esophageal cancer and can be extremely fatal if left untreated. Compared to open repair, thoracic endovascular aortic repair (TEVAR), a less invasive technique, is the initial recommended treatment in cases of hemorrhagic shock secondary to AEF, as this procedure showed a favorable outcome in controlling the overt bleeding. Here, we present a case of a patient with a history of stage IV esophageal cancer being treated with chemotherapy and an esophageal stent due to a previous tracheoesophageal fistula who presented to the emergency room due to severe gastroesophageal bleeding and hemorrhagic shock. A CT angiography of the chest revealed an AEF. The patient was subsequently resuscitated and treated with TEVAR. After the procedure, the hemorrhage was managed, and the patient was discharged with palliative radiation therapy. However, after one month, the patient had a major gastrointestinal hemorrhage, which caused her death. This example indicates the necessity of early detection and surgical intervention in AEF patients with unstable hemodynamics who have underlying unresectable esophageal cancer and chemotherapy. TEVAR should be conducted as soon as possible before the open surgery to achieve the best outcome for patients.
