目的探讨彩色多普勒超声在产前诊断胎儿先天性心脏复杂畸形中的应用价值。方法对1164例行产前检查的孕妇采用胎儿心脏彩色多普勒超声检查,其检查结果与经引产后的尸检及出生后胎儿检查结果进行对照。结果本研究检查的1164例胎儿中,产后胎儿检验结果或引产后胎儿尸检结果为192例单发心脏畸形,77例复杂畸形,另有8例单纯室间隔缺损、3例单纯肺动脉狭窄被漏诊。胎儿心脏彩超诊断心脏畸形的诊断符合率为99.05%(1153/1164),灵敏度为96.07%(269/280),特异度为100.00%(884/884),其中,诊断复杂心脏畸形的符合率为100.00%(77/77)。结论彩色多普勒超声诊断胎儿先天性心脏复杂畸形符合度高,其操作简便、无创,可为指导复杂先心的临床干预提供重要的技术支持。
Objective To explore the value of color Doppler sonography in prenatal diagnosis of fetal congenital heart defects. Methods A total of 1164 pregnant women undergoing prenatal examination were examined by color Doppler sonography of fetal heart. The results were compared with autopsy and postnatal fetal examination. Results Among the 1164 fetuses examined in this study, 192 cases of single heart malformation, 77 cases of complex deformity, 8 cases of simple ventricular septal defect and 3 cases of simple pulmonary artery stenosis were missed by the results of postnatal or postnatal fetal autopsy. The coincidence rate of fetal heart ultrasound diagnosis of cardiac malformation was 99.05% (1153/1164), the sensitivity was 96.07% (269/280) and the specificity was 100.00% (884/884). The coincidence rate of diagnosing complicated heart malformation was 100.00% (77/77). Conclusion Color Doppler ultrasound diagnosis of fetal congenital heart malformations with high compliance, its easy to operate, noninvasive, can provide guidance for the clinical intervention of complex heart provide important technical support.
