RESUMEN
A 59-year-old man was referred to our hospital for surgery for a dissecting aortic aneurysm with an aberrant right subclavian artery( ARSA). He had a history of surgery for atrial septal defect at the age of 3 and developed Stanford type B aortic dissection at the age of 53. The maximum diameter of the aortic aneurysm was 68 mm, and the entry was located close to the ARSA origin. We established cardiopulmonary bypass using the femoral artery and vein and performed a median re-sternotomy. We performed total arch replacement with the open stent-grafting technique. The ARSA was ligated from the right thoracic cavity. Three arch branches were reconstructed in situ, and the right axillary artery was bypassed with a 9 mm Dacron graft. Six months after that operation, reduction of the false lumen was observed. This strategy is considered to be effective for chronic aortic dissection with ARSA.
