Cardiac surgical procedure and catheter intervention of the aorta or its major branches have a potential risk for iatrogenic aortic dissection. This case demonstrates an iatrogenic type A aortic dissection after the elective balloon angioplasty for severe stenosis of the left subclavian artery orifice. The dissection retrospectively extended to the ascending aorta, and intramural hematoma was observed in the false lumen of the aorta. The ascending aorta was successfully replaced 14 days after the occurrence of dissection, using hypothermic circulatory arrest and antegrade selective cerebral perfusion. There were no outstanding complications.
