A 68-year-old man was referred to our hospital with an abnormal shadow on chest X-ray film. Enhanced chest CT scan revealed intrathoracic left subclavian artery aneurysmimaximum diameter 4cm) just above the aortic arch. Surgery was indicated considering the risks of aneurysm rupture and distal embolism, although he was asymptomatic. Under left 4th posterolateral thoracotomy, the aneurysm was exposed. Cardiopulmonary bypass was initiated with cannulation of the left femoral artery and vein (to the right atrium). Circulatory arrest and isolated cerebral perfusion were achieved at 25 core-temperature. The distal arch was replaced using a 26mm Hemashield graft and the left subclavian artery was reconstructed interposing an 8mm graft. The postoperative course was uneventful: he was extubated at 8h and was sent to the ward the next day. He was given an ambulatory discharge on the 13th postoperative day.
