Subclavian artery aneurysm is rare and sometimes seems difficult to decide an approach for surgery because it is surrounded by clavicle, ribs and apex of lung. Here, we are presenting a successfully treated case of right subclavian artery aneurysm with upper partial sternotomy. A 73-year-old man complaining of hoarseness was admitted to our hospital. CT scan revealed left subclavian artery aneurysm 5 mm distal to brachiocephalic trunk with 57×68 mm. Reversed L-shaped partial sternotomy was performed at the 2nd intercostal space, and the skin incision was extended to the superior border of clavicle. He underwent brachiocephalic-right subclavian artery bypass with an ePTFE graft excluding the aneurysm. Post-operative contrast-enhanced CT showed no blood flow in the aneurysm and good blood flow in the bypass. The upper partial sternotomy is considered useful approach for subclavian artery aneurysm.
