A remnant left aortic arch and a right aortic arch as well as Kommerell's diverticulum with an aberrant left subclavian artery.

We report the case of a 63-year-old woman who had dysphagia and dyspnea for one year. Enhanced computed tomography revealed that she had an ascending aortic dorsal projection and a right aortic arch as well as Kommerell's diverticulum (KD) with an aberrant left subclavian artery (LSA). Her KD compressed her trachea and esophagus. We cut her aorta just distal to the KD and performed an ascending and total arch replacement through a midsternotomy. The LSA was reconstructed in front of her trachea. Her dysphagia and dyspnea disappeared following the operation and her postoperative course was uneventful.
