Aberrant subclavian artery causing difficulty in transhiatal esophageal dissection.
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.
