Surgical treatment of Kommerell's diverticulum

Kommerell's diverticulum (KD) is a rare congenital vascular abnormality due to the formation of an abnormal aortic arch, most commonly associated with dilatation at the proximal part of the aberrant subclavian artery. This article describes an option of surgical treatment in a patient with KD. The proposed new technique of aortic arch surgical reconstruction with a stent‐graft placement in the descending aorta reduces CPB time, aortic clamp and circulatory arrest time.
