Intrathoracic Aneurysm of the Innominate and Right Subclavian Arteries: Report of a Case

Abstract

Aneurysms of the innominate and subclavian arteries are uncommon but associated with high mortality rates. We report herein the case of a 45-year-old man who presented with facial anhidrosis that developed several years after blunt thoracic trauma, in whom an aneurysm involving the innominate and subclavian arteries was revealed by preoperative examinations. Resection of the aneurysm and reconstruction from the ascending aorta to both the subclavian and common carotid arteries using a bifurcated graft was successfully performed without brain perfusion. Although the left posterior cerebral artery, which was not manipulated during surgery, became occluded, it was recanalized by thrombolysis. The patient was discharged in good health and has remained well since.
