A median ternotomy was performed and the incision was extended for 10 cm. towards while crossing the left clavicle. A 12 mm. Dacron graft bypass was perform ed between arcus aorta and descending thoracic aorta. Later.the three outlets of the aneurysms were ligated with teflon bands . Another bypass with 6 mm. Gore­ Tex graft was performed between'the graft and left subclavian artery. There were no complication and the pat i ­ ents is doin@ well at two year follow up.
