A 78-year-old female was referred to our hospital with a diagnosis of type A acute aortic dissection. There was a history of thrombosed aortic dissection six months prior and conservative management has been performed.

Emergency hemiarch replacement was performed under mild hypothermic circulatory arrest and selective antegrade cerebral perfusion. Due to preoperative paralytic ileus, oral intake was initiated postoperative day four. Postoperative computed tomography revealed improvement of paralytic ileus
