Dual-source CT Angiography in the Diagnosis of Congenital Aortic Valve Leaf Malformation Dual-source CT Angiography in the Diagnosis of Congenital Aortic Valve Leaf Malformation

目的探究双源CT血管成像在先天性主动脉瓣叶畸形中的诊断价值。方法选取2013年4月-2015年4月期间在我院诊断为先天性主动脉瓣叶畸形的患者100例,采用随机数字表法随机分成两组,其中观察组患者50例,对照组患者50例,观察组采用双源CT血管成像进行检测,对照组采用经胸超声心动图检测,选取检测的CT原始图像数据皆上传到工作站。对检测的原始数据再进行矢状位,冠状位以及虚拟内镜的相关技术处理,对主动脉瓣叶畸形的表现类型,瓣膜增厚情况,是否有钙化,卷曲,左心室增大以及其他合并畸形等现象。对患者主动脉最大径,左心室的舒张末期以及主动脉瓣膜的厚度进行分析。结果研究结果发现,两组患者各项指标相比均无明显差异(P>0.05)。结论双源CT血管成像在先天性主动脉瓣叶畸形中的有着明显的诊断价值,其与超声心动图检测结果基本一致,临床上能够准确诊断先天性主动脉瓣叶畸形,因其操作简单,准确性高,对患者伤害小,可以推广普及使用。

Objective To explore the dual-source CT angiography in the diagnosis of congenital aortic valve leaf malformation. Methods 100 cases of patients were selected during April 2013-April 2015 in our hospital diagnosed as congenital aortic valve leaf malformation , randomly divided into two groups by random number table method, the team of 50 Cases of patients, 50 patients with the control group, the group USES the dual-source CT angiography for testing, control group adopts the thoracic echocardiography examination, selection test of CT data are uploaded to the original image workstation. For detection of original data and then to sagittal and coronal position and processing the relevant technology of the virtual endoscopy, the type, the performance of aortic valve leaf malformation valve thickening, calcification, curly, left ventricular enlargement, and other abnormal phenomenon such as merger. For patients with aortic maximum diameter, left ventricular end-diastolic and the thickness of the aortic valve is analyzed, Results The results showed that the two groups of patients compared the indicators are no significant difference（P〉0.05）. ConclusionDual-source CT angiography in congenital aortic valve leaf malformation has obvious diagnostic value, almost the same with the testing results of echocardiography, can accurately diagnose congenital aortic valve leaf malformation, clinically because of its simple operation, high accuracy, small damage to patients, to promote its widespread use.
