摘要
目的:探讨连续顺序追踪超声检查法(systematic continuous sequence approach,SCSA)在产前胎儿畸形诊断中的价值。方法:应用多普勒超声仪,对16685例孕龄14周至40+3周的胎儿进行全身各系统的SCSA检测,观察胎儿整体结构、形态、姿势及运动等情况。结果:16627例胎儿进行SCSA检查获得满意的超声图像,占参检胎儿总数的99.65%。经产后证实的胎儿畸形514例,其中SCSA产前检出畸形胎儿498例(96.89%),漏诊16例(3.11%)。SCSA诊断胎儿畸形的敏感性、特异性、阳性预测值、阴性预测值分别为96.98%,99.96%,98.66%,99.90%。结论:SCSA是显示胎儿结构及诊断胎儿畸形的高效影像学诊断手段。
Objective To explore the value of uhrasonographic evaluation in fetal deformity in prenatal diagnosis by a systematic continuous sequence approach （SCSA）. Methods Successive prenatal uhrasonographic evaluation was performed to monitor the whole anatomic structure, form, posture and movement of 16 685 fetuses during gestation aging 14-40^＋3 weeks. Results Satisfactory ultrasonic images were obtained in 16 627 fetuses using the SCSA（99.65% ）. Of them, 514 abnormal fetuses were confirmed after subsequent labor or induced labor and 498 abnormal fetuses were correctly diagnosed using SCSA during prenatal stage （96.89%）. Whereas 16 fetuses missed recognition （3. 11% ）. Its sensitivity, specificity, positive and negative predictive value of diagnosis on fetal deformity were 96.98% , 99.96% , 98.66% , and 99.90 % , respectively. Conclusion SCSA in prenatal uhrasonographic evaluation of the fetal structure and malformation is reliable and accurate.
