An adult patient presenting a congenital vascular anomaly of the aortic arch and ring formation, surrounding trachea and esophagus, by compression of the latest was complaining of progressive dysphagia. A surgical approach was performed by right lateral thoracotomy with ressection of the Kommerell diverticulum, section of the arterious ligament and single ligation of the subclavian artery which was followed by total regression of the symptoms. No subclavian steal syndrome or ischemia was observed on the left upper limb. The authors discuss the manner of approach and surgical treatment of this rare anomaly.
