title: Rupture of Kommerell diverticulum after total arch replacement.
abstract: A 62-year-old man was brought to the emergency room of our hospital because of chest pain. Computed tomography revealed a right aortic arch and an aberrant left subclavian artery with Kommerell diverticulum and acute aortic dissection (Stanford type A). Total arch replacement was performed emergently through a median full sternotomy. A stomach feeding tube was placed postoperatively for the patient to receive nutrition, and esophageal bleeding was observed postoperatively. The patient died because of the bleeding. Autopsy findings showed a communication between the esophagus and Kommerell diverticulum. Rupture of Kommerell diverticulum and perforation of the esophagus were indicated.
