目的评价不同切面超声心动图检查在胎儿心血管畸形筛查中的诊断价值。方法通过对3000例20-28周的孕妇进行不同切面超声心动图检查及部分染色体核型检查及尸检结果,统计分析不同切面超声心动图检查对各种胎儿心脏畸形的检出率及敏感性。结果诊断先天性心脏病34例,发病率为1.1%,其中明确诊断27例,漏诊6例,误诊1例,标准三切面筛查的诊断敏感性为77.8%。结论标准三个切面超声心动图检查对胎心血管畸形筛查有较高的敏感性及特异性,是胎儿心脏心血管畸形筛查的首选方法。
Objective To evaluate the diagnostic value of echocardiography with different aspects in the screening of fetal cardiovascular malformations. Methods 3000 pregnant women of 20-28 weeks were examined by different section echocardiography and some karyotypes and autopsy results. The detection rate and sensitivity of various fetal echocardiography were statistically analyzed. Results The diagnosis of congenital heart disease in 34 cases, the incidence was 1.1%, of which 27 cases of definite diagnosis, 6 cases of missed diagnosis, 1 case of misdiagnosis, the diagnostic sensitivity of the standard tripartite screen was 77.8%. Conclusion The standard three-section echocardiography has a high sensitivity and specificity for the screening of fetal cardiovascular malformations, and is the preferred method of screening for fetal cardiovascular malformations.
