摘要
目的:探讨双源64层CT(DSCT)在诊断复杂先天性心脏病(CCHD)中的应用价值,并与经胸超声心动图(TTE)进行对照研究。方法:对186例CCHD患者同期行DSCT和TTE检查,以手术结果为标准,在心内异常解剖、心外大血管畸形的诊断上进行回顾性分析。结果:手术证实心血管畸形共538处。DSCT检出506处,检出率为94.1%,TTE检出497处,检出率为92.4%,两者差异无统计学意义,但两者联合检查检出529处,检出率达98.3%,明显高于单项检查(P<0.01)。其中,①心脏部分畸形:共209处,DSCT检出190处,检出率为90.9%,TTE检出200处,检出率为95.7%,两者差异无统计学意义;②心脏-大血管连接部分异常:共103处,DSCT检出94处,检出率为91.3%,TTE检出91处,检出率为88.4%,两者差异无统计学意义;③大血管部分畸形:共226处,DSCT检出222处,检出率为98.2%,TTE检出206处,检出率为91.1%,两者差异有统计学意义(P<0.01),DSCT检出率显著高于TTE。结论:①DSCT诊断心外大血管畸形的检出率高于TTE,对可疑并发大血管畸形的复杂先天性心脏病应作为常规检查手段;②DSCT与TTE联合应用可提高CCHD术前诊断的检出率。
To evaluate the clinical value of dual-source computed tomography （DSCT） in diagnosis of complex congenital heart diseases （CCHD） using a control study with transthoracic ultrasound cardiogra- phy （UCG）. METHODS： DSCT and UCG were performed in 186 patients with CCHD and their diagnosis of cardiovascular anomalies was later surgically confirmed and compared. RESULTS： In all patients, 538 cardiovascular anomalies were confirmed. Accuracy of DSCT and UCG was 94. 1% and 92.4%, re- spectively, and diagnostic accuracy showed no statistical difference （P=0. 281 ）. Of the 209 confirmed intracardiac anomalies, DSCT detected 190 （90. 9% ） and UCG detected 200 （95.7%）, with no statistical difference in the diagnostic accuracy rate （P = 0. 052）. Of the 103 confirmed heart-vessel conjunction anomalies, DSCT detected 94 （91.3%） and UCG detected 91 （88.4%）, also with no statistical difference in the diagnostic accuracy rate （ P = 0. 629 ）. Of the 226 confirmed great vessel anomalies, statistical difference was observed in the diagnostic accuracy between the 222 （98.2%） detected by DSCT and the 206（91.1% ） detected by UCG （P 〈0. 01）, showing that DSCT was superior to UCG. CONCLUSION： DSCT is superior to transthoracic UCG in the diagnosis of great vessel anomalies and can be used as one
