Neck Dissection and Thoracoscopic Esophagectomy in Esophageal Cancer with Aberrant Subclavian Artery

Abstract

We report a case of esophageal cancer with a non-recurrent inferior laryngeal nerve associated with aberrant right subclavian artery treated with neck dissection followed by thoracoscopic esophagectomy. A 60-year-old man experienced esophageal cancer, hoarseness, and left supraclavicular lymph node swelling was noted on endoscopy. Computed tomography revealed an aberrant right subclavian artery between the esophagus and vertebrae. We administered neo-adjuvant chemotherapy and performed thoracoscopic esophagectomy. During the neck dissection, we confirmed a non-recurrent inferior laryngeal nerve along the inferior thyroid artery. After the neck dissection, we performed thoracoscopic esophagectomy. We confirmed an aberrant right subclavian artery arising from the aortic arch, and resected the left recurrent nerve due to cancer invasion. No postoperative complication was observed, and the patient was discharged 17 days after surgery. Thus, we recommend prior neck dissection in cases involving aberrant right subclavian artery during esophagectomy.
