This report presents a case of DeBakey IIIb aortic dissection originating in a distal aortic arch fusiform aneurysm. The atherosclerotic change of the aneurysm was mild and the letter "C"-shaped intimal flap was turned over to obstruct the true lumen blood flow. A four-branched woven Dacron vascular prosthesis was implanted in a double barrel fashion. Although this case was successfully managed, an emergent operation should have been conducted.
