[Two Cases of Local Recurrence in the Descending Aorta after Radical Esophagectomy, Resected after Placement of a Thoracic Endovascular Stent].

Case 1 was that of a 65-year-old woman. Radical esophagectomy was performed after neoadjuvant chemotherapy(NAC) for lower thoracic esophageal cancer. Nineteen months after surgery, local recurrence was indicated on the dorsal side of the descending aorta. After chemoradiotherapy(CRT)and chemotherapy, residual cancer with aortic invasion was diagnosed. Case 2 was that of a 64-year-old man. Radical esophagectomy was performed after NAC for middle thoracic esophageal cancer. Five months after surgery, local recurrence was indicated between the descending aorta and left inferior pulmonary vein. After CRT and chemotherapy, residual cancer with invasion of the aorta and left lung was diagnosed. In both cases, we inserted an aortic stent and safely performed residual cancer resection including the aortic adventitia. In summary, aortic stent insertion enables safe resection of local recurrent tumors in the aorta after radical esophagectomy.
