- Abstract: We report two cases of total arch replacement with open stent graft for the aberrant right subclavian artery (ARSA). Case 1 was a thoracic artery aneurysm with an ARSA. We thought it would be difficult to perform in-situ reconstruction of ARSA via median sternotomy, so we performed total arch replacement with the open stent-grafting technique. Therefore the right axillary artery was reconstructed by extra-anatomical bypass and coil embolization of the ARSA proximal to the vertebral artery to achieve complete thrombosis of the ARSA. The postoperative course was uneventful. Case 2 was a Stanford type A acute aortic dissection involving an ARSA with the entry located near the ARSA. Total arch replacement was performed using the open stent-grafting technique to close the entry site and origin of the ARSA. Then the right axillary artery was reconstructed by extra-anatomical bypass and coil embolization of the ARSA. The postoperative course was uneventful. The open stent-grafting technique might be an effective alternative management of thoracic aortic disease with ARSA.
