本文分析了120例经血管造影、磁共振成像和(或)手术、病理证实的主动脉夹层的X线平片征象及其诊断评价。全组X线平片诊断符合率为67.5%。Ⅰ和Ⅲ型为72%和71.3%,Ⅱ型为50%。急性和亚急性病例为69.2%,慢性病例为62.8%,慢性Ⅲ型夹层平片征象须与同样部位的主动脉瘤样扩张鉴别。升主动脉高度扩张。同为Ⅰ、Ⅱ型夹层和马凡氏征主动脉病变的基本征象,后者又常并发升主动脉夹层,X线平片对两者的鉴别很少帮助,确诊应作超声心动图和造影检查。本文提出慢性主动脉夹层的诊断进程是放射—临床,而急性和亚急性夹层的诊断进程是临床—放射。
This article analyzes the 120 cases of angiography, magnetic resonance imaging and (or) surgery, pathological evidence of aortic dissection X-ray findings and its diagnostic evaluation. The whole group of X-ray diagnosis coincidence rate of 67.5%. Types I and III are 72% and 71.3%, and Type II is 50%. Acute and subacute cases were 69.2%, 62.8% of chronic cases, chronic type III dissection signs must be the same site with aortic aneurysmal dilatation identification. Ascending aorta height expansion. With the type Ⅰ, type II sandwich and Marfan signs of aortic lesions of the basic signs, and the latter often complicated by the rise of the aortic dissection, X-ray of the differential between the two seldom help, diagnosis should be done for echocardiography and contrast an examination. This paper suggests that the diagnostic process of chronic aortic dissection is radiation-clinical, whereas the diagnostic process of acute and sub-acute dissection is clinical-radiation.
