320排CT在先天性心脏病诊断中的应用

目的:探讨320排CT对先天性心脏病的临床诊断价值。方法:回顾性分析15例先天性心脏病患者的320排CT扫描资料,并与经胸超声心动图(TTE)及手术结果进行对照研究。结果:15例经手术证实的心内外结构异常共72个,其中心内结构异常27个,心外结构异常45个。320排CT、TTE对心内畸形的诊断符合率分别为96.3%(26/27)和92.6%(25/27),差异无显著性意义(χ2=2.982,P>0.05)。320排CT对心脏大血管连接部位畸形及心外大血管畸形的诊断符合率100%(45/45)]明显高于TTE53.3%(24/45)],差异有显著性意义(χ2=31.28,P<0.05)。320排CT及TTE对先心病总的诊断符合率分别为98.6%和68.0%,差异有显著性意义(χ2=28.09,P<0.05)。结论:320排CT对心外大血管结构异常的检出显著优于TTE,对心内结构异常的检出也有良好的效果,320排CT结合TTE可显著提高对小儿先心病的诊断准确性。

Application of 320-detector row computed tomography in the diagnosis of congenital heart diseases

Objective：To study the value of 320-detector row computed tomography 320-CT in the clinical diagnosis of congenital heart diseases. Methods： The 320-CT materials of 15 cases with congenital heart diseases were analyzed retrospectively and correlated to the findings of transthoracic eehocardiography （TTE） and surgery. Results：Totally 72 intra-and extra-cardiac anomalies were diagnosed,including intra-cardiac （n= 27） and extra-cardiac anomalies （n= 45）. Of 27 intracardiac anomalies,26 （96.3%） were identified by 320-CT while 25 （92.6%） of them were detected by TTE,with no significant statistic difference （2= 2. 982, P〉0. 05）. All of the extra-cardiac anomalies were demonstrated by 320-CT, while only 24 （53.3%） were detected by TTE, with significant statistic difference （X^2 = 31.28, P〈0.05）. The overall diagnostic accuracy was 98.6 % for 320-CT and 68 V0 for TTE, with significant statistic difference （X^2 = 28.09, P〈0.05）. Conclusion： 320-CT is obviously superior to TTE in the detection of extra-cardiac structural anomalies in congenital heart diseases,the results of detecting intra-cardiac anomalies were good,320-CT in combination with TTE can significantly improve the diagnostic accuracy of congenital heart disease in children.
