We present a rare case of common carotid artery with acute type A aortic dissection. A 72-year-old woman underwent emergent aortic arch repair using Antegrade selective cerebral protection. Bottom-tapped cannulae were inserted into three orifices of arch vessels, however, regional cerebral oxygen saturation decreased after rewarming. We found that arch branches were in order from front to back, right subclavian artery, common carotid trunk, and left subcravian artery. The patient complicated stroke in the right middle cerebral artery.
