AbstractA 43-year-old man was referred to our hospital with chest pain. Computed tomography revealed thrombosed type B aortic dissection and distal aortic arch aneurysm with maximum diameter of 56 mm accompanied by an aberrant right subclavian artery (Kommerell's diverticulum). After performing anti-hypertensive treatment, we planned surgical treatment the operation. Graft replacement of distal aortic arch aneurysm was performed through left posterolateral thoracotomy with deep hypothermic circulatory arrest. The aberrant right subclavian artery was reconstructed with an interposed graft. Postoperative course was uneventful and he was discharged on the 9th postoperative day. Kommerell's diverticulum with aortic dissection is a relatively rare condition. Here we describe our surgical strategy with a review of the literature.
