Computed tomography is frequently used in the initial workup of patients with suspected aortic dissection to distinguish dissection involving the ascending aorta from dissection limited to the descending aorta. We reviewed CT of 19 patients who were proven by aortography to have normal ascending aortas. In eight patients the superior extension of the pericardium was visualized and thought to be a potential source of a false-positive diagnosis of type A aortic dissection.
计算机断层扫描常用于对疑似主动脉夹层患者进行初步检查，以区分累及升主动脉的夹层与局限于降主动脉的夹层。我们回顾了19例经主动脉造影证实升主动脉正常的患者的CT扫描结果。在8例患者中，心包的上延部分被可视化，被认为是A型主动脉夹层假阳性诊断的潜在来源。
