Abstract
A 60-year-old male was transferred to a critical care medical center with a complaint of sudden back pain. He already had suffered severe back pain 22 years previously when he was 38-year-old), but was not diagnosed then. On admission thoracic CT scan revealed a three-channeled structure in the descending aorta. The preoperative diagnosis was an acute redissection of a DeBakey III b dissecting aortic aneurysm. An emergency graft replacement of the descending aorta confirmed the three-channeled structure of the aorta. The remaining of media of the aorta, which occurred in the re-dissected lumen, was thin and weak. The patient was alive and well twenty-five months following the operation.
