[Aortic dissection presenting with neurologic sign; report of a case].

A 59-year-old man was admitted to our hospital for neurological deficit and left hemiplegia, presenting remission in the short time. Computed tomography(CT) of the brain was normal. CT of the chest showed a thoracoabdominal aortic dissection from the ascending aorta to the bilateral femoral artery, that involved all cervical arteries. The intimal flap separated the false and true lumens and there was flow in both lumens. That phenomenon can be due to the extension of the dissection along the aorta, occluding the origin of the cervical arteries and the change of the flow by the intimal flap. He was amputated his left leg below knee on the 1 postoperative day (POD), but discharged at 70 POD without neurologic complications.
