ABSTRACT The right subclavian artery normally arises from the brachiocephalic artery. Anomalies in development may lead to peculiar problems during surgery. We report a patient with esophageal carcinoma who had an aberrant right subclavian artery, posing specific difficulties during a transhiatal esophagectomy, requiring conversion of the procedure into a transthoracic approach. The embryologic basis of this anomaly and the clinical significance are discussed.

    ABSTRACT: We report a case of carcinoma of the hypopharynx and cervical esophagus in a patient with an aberrant right subclavian artery. Barium esophagography, endoscopy, and computed tomography showed a resectable tumor in the hypopharynx and cervical esophagus, coexistent with an aberrant right subclavian artery. We performed pharyngolaryngoesophagectomy with bilateral neck dissection and gastric pull-up through cervical, right thoracic, and abdominal incisions. We also partially resected the aberrant right subclavian artery with reimplantation in the right common carotid artery. To our knowledge, this is the first report of pharyngolaryngoesophagectomy with transposition of an aberrant right subclavian artery.

    ABSTRACT: When performing video-assisted thoracoscopic esophagectomy, the area at the level above the aortic and in the space between the esophagus and the spine, is usually regarded as a safe area for dissection of upper segment of thoracic esophagus. However, an aberrant right subclavian artery may appear in this area and lead to disastrous complications. We reported a case of aberrant artery encountered during video-assisted thoracoscopic esophagectomy. In order to avoid iatrogenic damage to this artery, it was converted to thoracotomy.

    ABSTRACT: An aberrant right subclavian artery (ARSA) is an anatomical abnormality that occurs at a frequency of 0.4–2 %. It is important to be aware of this abnormality when performing radical esophagectomy for esophageal cancer because many patients with an ARSA have a right nonrecurrent inferior laryngeal nerve (NRILN) and right thoracic duct. We report three cases of esophageal cancer with ARSA treated by thoracoscopic esophagectomy. Case 1 was a 59-year-old woman with a relapse of a thoracic esophageal cancer after definitive chemoradiotherapy (CRT). Case 2 was a 76-year-old man with upper thoracic esophageal cancer who had received no treatment before the surgery. Case 3 was a 69-year-old man with upper thoracic esophageal cancer pretreated with neoadjuvant CRT. It was possible to predict an ARSA by computed tomography and the right thoracic ducts by magnetic resonance imaging before surgery in all three cases. Thoracoscopic esophagectomy with two-field lymph node dissection was performed, and the NRILN and the right thoracic duct were detected and preserved in all three cases. Because of ARSA, the operative field is limited around the left recurrent nerve, so a careful procedure is needed to avoid nerve palsy.
