64层螺旋CT诊断复杂先天性心脏病及与超声心动图和手术对照

目的探讨64层螺旋CT对复杂先天性心脏病(简称复杂先心病)的诊断价值。资料与方法对25例复杂先心病患者的心脏CT和超声心动图(TTE)进行回顾性分析,并与手术结果对照。全部病例均经手术证实。结果25例患者中手术证实畸形79处,64层螺旋CT与TTE诊断的准确率分别为96%和73%。其中,心脏部分畸形29处,64层螺旋CT漏误诊2处,TTE漏误诊4处,两种检查的诊断准确率差异无统计学意义。心脏-大血管连接部及大血管部分畸形50处,64层螺旋CT漏误诊1处,TTE漏误诊17处,两种检查的诊断准确率差异有统计学意义。结论64层螺旋CT在复杂先心病诊断中畸形的检出率优于TTE,诊断准确率达96%,特别是对主动脉、肺动脉及肺静脉畸形的显示具有明显优势。

The Clinical Application of 64 slice Computed Tomography in the Diagnosis of Complex Congenital Heart Disease

Objective To discuss the clinical value of 64 slice computed tomography (64 slice CT) in the assessment of deformities in patients with complex congenital heart disease. Materials and Methods Imaging data of 64 slice CT and transthoracic echocardiography (TTE) obtained in 25 preoperative patients were analyzed retrospectively. Results were confirmed and compared with surgery. Results In the 25 preoperative patients, there were 79 deformities confirmed by surgery. The accuracy of 64 slice CT and TTE were 96% and 73%. There were 29 intracardiac deformities, 2 missed by 64 slice CT, 4 missed by TTE. The diagnosis accuracy between 64 slice CT and TTE had no difference. There were 50 extracardiac deformities, 1 missed by 64 slice CT and 17 missed by TTE. 64 slice CT was superior to TTE in the detection of extracardiac deformities. Conclusion 64 slice CT is superior to TTE in the diagnosis of complex heart diseases, especially in displaying the aortic congenital disease, pulmonary artery development, anomalous pulmonary drainage and system pulmonary collateral circulation.
