Abstract
A 76-year-old man was involved in a high speed motor vehicle accident, and brought to the emergency department. Computed tomography showed local type A aortic dissection with sternal fracture and splenic injury. We performed graft replacement of the ascending aorta 16 hours after admission under cardiopulmonary bypass with hypothermic circularory arrest. Intimal tear of the aorta was just above the aortic valve, and it involved the right lateral aortic wall. The postoperative course was uneventful.
