Background
Aortoesophageal fistula (AEF) is a
relatively rare condition that is often life-threatening. Secondary AEF
is a complication of previous surgery, and can be more critical and
challenging than primary AEF. The number of secondary AEF is increasing
due to increase in the number of thoracic endovascular aortic repair
(TEVAR). Although TEVAR has become a successful alternative surgical
strategy for thoracic aortic aneurysms, secondary AEF after TEVAR may
occur because of severe adhesion between the esophagus and residual
thoracic aortic wall.
