title: Successful surgical exclusion of rapidly expanding kommerell diverticulum following a total arch replacement for an acute type a aortic dissection.
abstract: A 50-year-old man presented with an acute type A aortic dissection with an aberrant right subclavian artery. Emergent total arch replacement with an elephant trunk was performed. Intraoperatively, the origin of the aberrant right subclavian artery could not be resected because it was located too far from the distal arch. After two weeks, the patient became aware of dysphagia. Postoperative computed tomography showed the esophagus was compressed anteriorly by the aneurismal origin of this aberrant vessel (Kommerell diverticulum) with a patent false lumen. Additional replacement of the descending aorta via left thoracotomy was performed immediately to exclude a Kommerell diverticulum.
