A 38-year-old man with polyarteritis nodosa presented with exertional chest pain. Coronary angiography revealed 3-vessel coronary artery disease. We performed 2-vessel coronary artery bypass grafting with the saphenous vein because the left internal thoracic artery was in poor condition. Histological examination of the left internal thoracic artery showed a strong effect of polyarteritis nodosa.

An 80-year-old woman underwent aortic valve replacement and ascending aortic replacement. Two years later, computed tomography revealed a pseudoaneurysm of the ascending aorta replaced with a prosthesis. The pseudoaneurysm arose from the stump of a side branch of the prosthesis. Endovascular treatment for the pseudoaneurysm was carried out using the aortic extension cuff of an infrarenal endovascular system. The postoperative course was uneventful.

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 extraanatomical 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.
