1.Introduction
Thoracic aortic endovascular repair (TEVAR), as a minimally invasive treatment for aortic diseases, has been used more and more clinically, but problems such as stent leakage, re-intervention and infection are still very serious. According to literature reports, the incidence of AEF (aortic esophageal fistula) after TEVAR is 1.9%, but the condition is dangerous and complicated, and the mortality rate is high[1]. For AEF after TEVAR, most scholars believe that open surgery is the root treatment of AEF[2-5]. Aortic replacement combined with esophagectomy and debridement at the same time or by stages is an effective treatment, but complications such as hemorrhage and sepsis may occur [6-8]. However, the specific surgical methods, aortic reconstruction methods, and esophagus resection or repair are still inconclusive. The Department of Cardiovascular Surgery of DeltaHealth Hospital uses ascending aorta-abdominal aorta bypass, ascending aorta-brachiocephalic bypass, removal of infected vessels with stents, and repair or resection of esophageal fistulas at the same time or in stages. Achieve better clinical efficacy, the single-center experience is now reported as follows.
