Thoracic endovascular aortic repair (TEVAR) has been performed in the treatment of thoracic aortic disease since the mid-1990s. Complications associated with TEVAR are increasing rapidly due to its widespread use. One of these complications is late lethal aortoesophageal fistula (AEF). The aim of this study was to describe the diagnosis of AEF in a 64-year-old woman 8 months after TEVAR. The AEF was diagnosed on a computed tomography angiography with oral and intravenous contrast. The patient underwent open surgical repair and died of sepsis 12 days after surgery.
