Aortic aneurysm: a rare cause of Ortner's syndrome.

A young man presented with hoarseness of voice and was found to have left vocal cord paralysis and a large opacity on chest X-ray in the left upper zone. CT angiography showed a giant aneurysm of the aortic arch involving the left subclavian artery. Using a dual perfusion system, with the femoral bypass circuit taking care of the spinal protection and the aortic bypass circuit providing the cerebral protection, the aneurysm was excised and a 16 mm Dacron graft was anastomosed to the aortic arch and the left subclavian artery was anastomosed to the interposition graft. He had a smooth postoperative course and his hoarseness subsided in next 6 months.
