摘要
目的探讨二维超声结合增强型血流成像技术诊断胎儿心脏畸形的应用价值。方法行胎儿超声心动图检查的1580例孕妇，应用二维超声结合增强型血流成像技术对胎儿心脏畸形进行筛查，与产后复查或引产后尸检对照。结果1580例中1286例获得完整随访资料，失访294例。二维超声结合增强型血流成像技术诊断胎儿心脏畸形的灵敏度为98．0％，特异度为99．3％，误诊率为2．0％，漏诊率为0．7％。二维超声结合增强型血流成像技术诊断胎儿心脏畸形的一致性评价Kappa值=0．970（P=0．000）。结论二维超声结合增强型血流成像技术是诊断胎儿心脏畸形的一种有效且可靠的方法，具有较高的灵敏度和特异度。
Objective To evaluate the diagnostic accuracy of two dimensional echocardiography combining with enhanced flow （e-flow） imaging for fetal heart malformation. Methods 1580 cases were screened for fetal heart malformation. The diagnostic accuracy was evaluated by comparing the results fetal echocardiography with those of postpartum echocardiography,surgery or autopsy. Results Antepartum and postpartum data were obtained in 1286 of the 1580 fetuses （81.39%）. Among the 1286 cases, the sensitivity, specificity, mistake diagnostic rate, omission diagnostic rate was 98.0 %, 99.30%, 2.0 %, 0.7 %, respectively. The consistency evaluation of fetal heart malformation by two dimensional echocardiography combining with e-flow concluded that the valve of Kappa was 0. 970 （ P = 0. 000）. Conclusions Two dimensional echocardiography combining with e-flow is an accurate and reliable method for diagnosing fetal heart malformation,it has a high sensitivity and specificity.
