双源CT诊断复杂先天性心脏病的价值

目的：探讨双源 CT(DSCT)诊断复杂先天性心脏病(CCHD)的价值。方法对46例 CCHD 患者、共107处畸形的DSCT血管图像与经胸壁超声心动图(TTE)及手术结果进行回顾性对照研究。结果手术证实心内畸形49处,心外畸形58处；DSCT与TTE诊断心内畸形准确率为81.63%(40/49)、93.88%(46/49),心外畸形准确率为94.83%(55/58)、58.62%(34/58),心内、外畸形总准确率为88.79%(95/107)和74.77%(80/107),两者差异有统计学意义；DSCT与TTE结合对心内、外畸形诊断准确率达到94.39%(101/107),高于单一DSCT、TTE,差异有统计学意义。结论 DSCT联合TTE提高CCHD的诊断准确率。

Application of dual-source CT in the diagnosis of complex congenital heart disease

Objective To analyze the value of dual-source computed tomography (DSCT)in the diagnosis of complex congenital heart disease(CCHD).Methods DSCT angiography and transthoracic echocardiography (TTE)were retrospectively assessed in 46 patients who were confirmed by surgery with 107 deformities.Results There were 49 intracardiac deformities and 58 extracardiac deformities.The diagnostic accuracies in detection of intracardiac malformation were 81.63%(40/49)on DSCT and 93.88%(46/49) on TTE,those in detection of extracardiac malformation were 94.83%(55/58)on DSCT and 58.62%(34/58)on TTE,and the overall accuracies of cardiovascular malformations were 88.79%(95/107)on DSCT and 74.77%(80/107)on TTE,respectively,exhibting statistical differences.The diagnostic accuracy of DSCT in combination with TTE in detection of intracardiac and extracardiac malformation was 94.39%(101/107),which was higher than DSCT or TTE with statistical differences.Conclusion The combination of TTE and DSCT is helpful to improve the diagnostic accuracy of CCHD.
