Aorto-esophageal fistula secondary after thoracic endovascular aortic repair.

Aortoesophageal fistula (AEF) secondary to thoracic endovascular aortic repair (TEVAR) is a rare clinical entity that poses a threat to life as it causes massive digestive bleeding, and it is estimated that 60% of patients who suffer from it could die within within 6 months of the onset of their symptoms. It requires a high clinical suspicion to establish an early multidisciplinary surgical treatment. We present the cases of two patients diagnosed with aortoesophageal fistulas after TEVAR in the last 5 years (January 2018-December 2022) while reviewing the existing scientific literature on the matter.
