[Total Arch Replacement with Open Stent Grafting Technique for an Aberrant Subclavian Artery Cousing Dysphagia;Report of a Case].

An aberrant right subclavian artery (ARSCA) is a relatively rare congenital anomaly of the aortic arch branches. A 63-year-old man suffered from dysphagia, and was referred to our hospital. Computed tomography (CT) revealed an aortic aneurysm (Kommerell's diverticulum) and ARSCA which routed behind the esophagus. We performed total arch replacement with the open stent-grafting technique via median sternotomy. ARSCA was anastomosed to 1 branch of the arch graft at the right side of the trachea, which released esophageal compression. Postoperatively dysphagia disappeared and CT scan indicated successful reconstruction of the distal arch and ARSCA. The open stent-grafting technique is considered to be effective for aortic disease with ARSCA.
