目的:分析产前超声筛查五步检查法对胎儿心脏畸形的诊断价值。方法:选取2016年5月至2017年4月收治100例产前产检孕妇为研究对象,随后对产妇进行超声筛查的五步检查法,最后分析此项检查方式在胎儿心脏畸形筛查中的重要性和价值性。结果:产前超声筛查五步检查法右心室双出口诊断正确率为100.00%,法洛四联症诊断正确率为100.00%,单心房单心室诊断正确率为80.00%,心内膜垫缺损诊断正确率为66.67%,房间隔缺损诊断正确率为100.00%,室间隔缺损诊断正确率为90.00%,其诊断结果和产后检查比较,差异均无统计学意义(P>0.05)。同时产前超声筛查五步检查法在胎儿心脏畸形诊断正确率、敏感度、特异度、误诊率、漏诊率分别为90.00%、90.00%、97.50%、2.50%、10.00%。结论:超声筛查五步检查法具有无创性、个性化、操作简单等优势,用于胎儿心脏畸形检查中,能够及时发现异常之处,利于早期干预。
Objective: To analyze the diagnostic value of five-step prenatal ultrasound screening for fetal cardiac malformations. Methods: From May 2016 to April 2017, 100 prenatal and postnatal pregnant women were enrolled in this study. Five-step ultrasound examination was performed on the pregnant women. The final screening method was used to screen fetal malformations Importance and value. Results: The correct rate of double-outlet right ventricle diagnosed by prenatal ultrasound screening was 100.00%, the correct rate of tetralogy of Fallot was 100.00%, the accuracy rate of single ventricle single ventricle diagnosis was 80.00%, endocardial cushion defect The diagnostic correct rate was 66.67%, the diagnostic accuracy of atrial septal defect was 100.00%, and the diagnostic accuracy of septal defect was 90.00%. There was no significant difference between the diagnosis and the postpartum examination (P> 0.05). At the same time, the correct rate, sensitivity, specificity, misdiagnosis rate and misdiagnosis rate of prenatal ultrasound screening five-step examination in fetal cardiac malformation were 90.00%, 90.00%, 97.50%, 2.50% and 10.00% respectively. Conclusion: Ultrasound screening five-step examination has the advantages of non-invasive, personalized, easy to operate and so on. It can be used in fetal malformation examination to detect abnormalities in time and facilitate early intervention.
