目的:探究并分析老年晕厥与主动脉弓凸显影像的相关性。方法选取自2004年11月~2011年11月我院收治的老年晕厥患者120例,将其作为观察组,另选取120例未出现晕厥的正常老年人,两组人员均进行胸部X线检查。观察两组患者X线胸片的影像学表现情况。结果观察组患者主动脉弓凸显影像的检出率为45.83%,主动脉弓影像凸显明显的检出率为21.67%,均明显高于对照组;观察组患者的主动脉直径明显小于对照组,且观察组患者的血压高于对照组、心输出量、射血分数明显低于对照组;X线胸片影像学结果显示,观察组患者双心室增大、肺血流瘀滞明显,肺动脉段瘤样突出的发生率分别为16.67%、15.83%,较对照组高,<0.05,具有统计学意义。结论主动脉弓凸显影像在老年性晕厥患者中的发生率较高,两者之间存在密切的关系。“,”Objective To study and analyze the correlation between elderly syncope and aortic arch highlight image. Methods 120 elderly patients with syncope treated in our hospital from November 2004 to November 2011 were selected as the observation group, and other normal elderly people without syncope were selected as the control group, and both the two groups received X ray examination on chest. Imaging manifestations of the X ray chest radiograph of patients in the two groups were observed. Results The relevance ratio of the aortic arch highlight image of patients in the observation group was 45.83%, while that of the obvious aortic arch highlight image of patients in the observation group was 21.67%, which were apparently higher than the control group; the aorta diameters of patients in the observation was less than those of the control group, when the blood pressure were higher than the control group, cardiac output, ejection fraction significantly lower than control group; the imaging manifestations of the X ray chest radiograph showed that the two ventricles of patients in the observation group enlarged, Pulmonary blood flow stasis is obvious,and the occurrence rates of the tumor highlighting of the pulmonary artery were respectively 16.67%, 15.83%, which were higher than those of the control group, with p<0.05, which is of statistical significance. Conclusion The occurrence rate of aortic arch highlight image is higher in the elderly patients with syncope, and they have a close relationship.
