title: Intrathoracic left subclavian artery aneurysm: report of a case.
abstract: Aneurysms of the intrathoracic subclavian artery are extremely rare. A 74 year-old man was referred to our hospital with an abnormal chest X-ray film. Contrast computed tomography revealed an intrathoracic left subclavian artery aneurysm. Via left 4th posterolateral thoracotomy, the aneurysm was exposed under systemic deep hypothermia and circulatory arrest. The distal arch was replaced with a 26 mm single-branched graft and the left subclavian artery was reconstructed with a 10 mm graft.
