Two-stage operation for Stanford type A acute aortic dissection originating from Kommerell's diverticulum.

We report a rare case of Stanford type A acute aortic dissection involving an aberrant right subclavian artery and originating from Kommerell's diverticulum in a 52-year old man. Initially, as an emergency measure, total arch replacement and right axillary artery reconstruction were performed. However, due to the subsequent enlargement of the false lumen, thoracic endovascular aortic repair and right subclavian artery coiling were performed successfully 5 months after the first operation. Herein, we describe surgical management approaches for the treatment of a Stanford type A acute aortic dissection with aberrant right subclavian artery.
