Preliminary Experience with Prophylactic Thoracic Endovascular Aortic Repair in Patients Affected by Advanced Esophageal Cancer.

Bleeding from the thoracic aorta is potentially fatal in patients with advanced esophageal cancer (AEC). Esophageal malignancy is the third most common cause of aortoesophageal fistula, after thoracic aortic aneurysm and ingestion of foreign body. The involvement of aortic wall often contraindicates chemoradiotherapy (CRT) treatment, thus reducing life expectancy of these patients. Thoracic endovascular aortic repair (TEVAR) is a well-described mini-invasive technique that can be also applied for coverage of the aortic lumen in case of invasion by esophageal cancer. Only few cases have been published with this atypical indication. Between 2016 and 2018, in our tertiary hospital 3 patients affected by AEC involving the thoracic aorta were treated by means of prophylactic TEVAR. All procedures were uneventful, and all patients were reconsidered fit for preoperative or definitive CRT.
