摘　　要：目的:探讨双源CT在复杂性先天性心脏病的诊断价值。方法:对20例经手术证实的复杂先心病患者的心脏双源CT(DSCT)和经胸壁超声心动图(TTE)检查资料进行回顾性分析。结果:20例患者中手术证实畸形84处,DSCT与TTE均检出69处,检出率为82.14%。其中,心脏部分畸形29处,DSCT检出率75.86%,TTE检出率93.10%,二者的检出率差异无显著性(P>0.05);心脏-大血管连接部畸形12处,DSCT检出率66.67%,TTE检出率83.33%,二者的检出率亦无显著差异(P>0.05);大血管部分畸形43处,DSCT检出率90.70%,TTE检出率74.42%,DSCT的检出率显著高于TTE(P<0.05)。结论:心脏双源CT对心外大血管畸形的检出率优于经胸壁超声心动图,可作为复杂性先心病的术前常规检查手段。Objective： To evaluate the clinical value of dual-source computed tomography （DSCT） in patients with complex congenital heart disease. Methods： Imaging data of DSCT and transthoracic echoeardiography （TTE） obtained in 20 patients before operatively were analyzed retrospectively. Results： In the 20 patients, their diagnosis of 84 deformities were confirmed by surgery. The accuracy of DSCT and TTE were same （82.14%）. There were 29 intracardiac deformities. 22 （75.86%） detected by DSCT, 27 （93. 10%） detected by TTE, the diagnosis accuracy between DSCT and TTE had no difference （P〉0. 05）. There were 12 heart-vessel conjunction deformities, 8 （66. 67 %） detected by DSCT and 10 （83.33%） detected by TTE, their diagnosis accuracy also had no difference （P〉0.05）. There were 43 great vessel deformities. 39 （90.70%） detected by DSCT and 32 （74. 420/oo） detected by TTE; diagnosis accuracy of DSCT was superior to TTE （90.70%： 74.42%, P〈0.05）. Conclusion： DSCT is superior to TTE in the diagnosis of great vessel deformities, may be one of the preoperative detection method of complex congenital heart disease.
