[A case of traumatic aneurysm of innominate artery with occlusion of right subclavian artery].
A 42-year-old woman with history of chest blunt trauma from an automobile accident 250 days earlier had suffered easy fatigability of the right upper extremity. She had difference of blood pressure between upper extremities, 94/60 mmHg in the right and 126/70 mmHg in the left. Chest CT showed dilation of the innominate artery which compressed the trachea. Aortography showed an aneurysm of the innominate artery and occlusion of the right subclavian artery at its origin. The aneurysm of the innominate artery was resected and replaced with a 6 mm Dacron graft with aid of the external shunt. The right subclavian artery was also reconstructed with same graft. The aneurysm of the innominate artery should be suspected as a rare complication in blunt trauma of the chest.
