Esophageal cancer with a double aortic arch: a case report and literature review

Abstract

Abstract Background Double aortic arch (DAA) is an extremely rare vascular malformation, even more so when coexisting with esophageal cancer. Methods We report a new case of DAA with esophageal cancer recently seen at our Thoracic Tumor Clinic and review cases of DAA coexisting with esophageal cancer reported in the literature of English language from 2010 to 2020. The purposes of our literature review were to explore how to best achieve radical esophagectomy while reducing postoperative complications. The clinical manifestations, diagnostic method, surgical approach, reconstruction route, and the extent of lymphadenectomy of esophageal cancer with DAA were analyzed in detail. Results and conclusion For such patients, 3D computed tomography is necessary for preoperative diagnosis. The surgical approach should consider factors such as the location of the tumor in the esophagus and whether the tumor is surrounded by DAA, as well as the position of the descending aorta and the requirements for the surgical field for lymphadenectomy. If esophageal reconstruction is required, the retrosternal route is preferred. We recommend that only patients with positive results of intraoperative frozen biopsy of recurrent laryngeal nerve lymph nodes should undergo three-field lymphadenectomy, which may be the best method to achieve radical esophagectomy for middle and lower esophageal cancers with DAA while minimizing postoperative complications.
