Successful management of life-threatening aortoesophageal fistula: A case report and review of the literature

Abstract

BACKGROUNDAortoesophageal fistula (AEF) is a rare but life-threatening cause of upper gastrointestinal bleeding. Only a handful of cases of successful management of AEF caused by esophageal cancer have been reported. The purpose of this study is to report a case of AEF managed by endovascular aortic repair and review the relevant literature.CASE SUMMARYA 66-year-old man with upper gastroenterology bleeding presented at the Emergency Department of our hospital complaining of chest pain, fever and hematemesis for 6 h. He had vomited 400 mL of bright-red blood and experienced severe chest pain 6 h prior. He had a past medical history of advanced esophageal cancer. He received chemoradiotherapy but stopped 8 mo prior because of intolerance. A chest contrast computed tomographic scan revealed communication between the esophagus and the descending aorta as well as a descending aortic pseudoaneurysm. According to the symptoms and imaging findings, AEF was our primary consideration. The patient underwent aortic angiography, which indicated AEF and descending aortic pseudoaneurysm. Emergency percutaneous thoracic endovascular aortic repair (TEVAR) of the descending aorta was performed, and bleeding was controlled after TEVAR. He received antibiotics and was discharged after treatment. However, he died 2 mo after the TEVAR due to cancer progression.CONCLUSIONAlthough AEF is a lethal condition, timely diagnosis and TEVAR may successfully control bleeding.
