[Arteria lusoria--a rare cause of dysphagia].

A rare case of a 29-year old woman with aberrant right subclavian artery (A. lusoria) causing dysphagia is presented. This abnormality is generally silent and often an incidental x-ray finding. By means of a median thoracotomy the anomalous vessel was divided at its point of origin and an anastomosis to the ascending aorta with a graft was performed.
