A 67-year-old woman developed a transient paraplegia as the initial manifestation of acute aortic dissection. Chest or abdominal pain was not present. Magnetic resonance imaging of the thorax demonstrated dissection of the aortic root, aortic arch, and descending aorta as well as pericardial effusion. Ultrasonography of the abdomen revealed an intimal flap in the region of the artery of Adamkiewicz. During aortic dissection, temporary obstruction of spinal arteries may result in transient paraplegia. Painless aortic dissection should be considered in patients who present with transient myelopathy.
一名67岁女性出现短暂性截瘫，作为急性主动脉夹层的初始表现。当时并无胸痛或腹痛症状。胸部磁共振成像显示主动脉根部、主动脉弓及降主动脉夹层，以及心包积液。腹部超声检查发现Adamkiewicz动脉区域存在内膜瓣。在主动脉夹层期间，脊髓动脉的暂时阻塞可能导致短暂性截瘫。对于出现短暂性脊髓病的患者，应考虑无痛性主动脉夹层。
