【摘要】：目的探究应用新技术对早孕期胎儿严重肢体畸形产前超声诊断价值。方法选择早孕期检查的孕妇5 843例初步筛选出147例疑似胎儿畸形,依次应用常规超声检查和连续顺序追踪超声法进行检查,并将常规超声检查结果记为对照组,连续顺序追踪超声法检查结果记为观察组。对比两种方法对早孕期胎儿肢体畸形的诊断结果,包括准确率、敏感性、特异性以及阳性预测值、阴性预测值等。结果经产后或临床结果得到肢体畸形胎儿为40例,占27.21%。观察组在对肢体缺失和其他肢体畸形检出率达到100%(14/14)和65.00%(13/20),显著高于对照组的50.00%(7/14)和5.00%(1/20)。但观察组在对手指畸形的检查未表现出优势。观察组检查的准确度、敏感性与阴性预测值为91.84%、70.00%、89.92%,均高于对照组的78.91%、22.50%、77.54%,差异均有统计学意义(P0.05)。结论应用连续顺序追踪超声法对早孕期胎儿肢体畸形的检查准确度高,为产前诊断以及后期胎儿处理提供了充足的时间。
[Abstract]:Objective to explore the value of new technique in prenatal ultrasound diagnosis of severe fetal limb malformations in early pregnancy. Methods 5843 pregnant women with early pregnancy were selected and 147 suspected fetal deformities were selected. The results of routine ultrasound examination and continuous sequential tracking ultrasound were recorded as the control group. The results of continuous sequential tracking ultrasound were recorded as observation group. The diagnostic results of the two methods for fetal limb deformity in early pregnancy were compared, including accuracy, sensitivity, specificity and positive predictive value. Results by postpartum or clinical results, 40 cases of extremity malformation were obtained. 27.21. The detectable rate of missing limbs and other deformities in the observation group was 100% 14 / 14) and 65.00% 13 / 20%, which was significantly higher than that in the control group (50.007 / 14) and 5.00% 20%. However, the observation group had no advantage in the examination of finger deformities. The accuracy of the observation group was higher than that of the control group. The predictive value of sensitivity and negative value was 91.84 and 70.00000 / 89.92, which was higher than that of the control group (78.91 / 22.50g / 77.54), and the difference was statistically significant (P 0.05). Conclusion the accuracy of continuous sequential tracing ultrasound in the detection of fetal limb deformity in early pregnancy is higher than that in the control group (P < 0.05). It provides sufficient time for prenatal diagnosis and post-fetal treatment.
