title: A bidirectional closing aortic dissection from an atherosclerotic distal aortic arch aneurysm: report of a case.
abstract: We experienced one rare case of a 76-year-old male with a Stanford type A bidirectional closing aortic dissection from a coexisting atherosclerotic distal arch aneurysm. He showed a cardiac tamponade, and effective pericardial drainage allowed us to conservatively manage the patient. Both an increase in the size of the aneurysm and a recrudescent dissection in the descending aorta were identified 2 months after the onset. A scheduled surgical repair was successful. The coexistence of an acute aortic dissection and an atherosclerotic aneurysm increases the risk of an aortic rupture, particularly at the confluence of the two lesions. Meanwhile, the management of a closing aortic dissection remains controversial because its characteristics still are not well known. We studied not only the pathogenesis but also the management of these two forms of aortic disease and their complex relationships.
