| 【】目的:分析不同年龄段孕妇产前超声筛查出的胎儿畸形差异性。 方法: 6119例进行产前超声筛查的孕妇,按年龄分成≤19岁、20～24岁、25～29岁、30～34岁、35～39岁以及≥40岁六组。选择经与产前诊断中心检查、引产后尸体检查或产后新生儿检查结果相比较,证实超声诊断正确的胎儿畸形,按组分析胎儿六大类严重畸形检出率、畸形数目及畸形类型。结果: 6119例孕妇共有胎儿畸形205例,超声诊断正确186例。≤19岁组六大类严重畸形检出率最高,差异有统计学意义(P＜0.05)。≥40岁组多发畸形发生率最高。畸形类型以先天性心脏畸形检出数最高,神经系统畸形、颜面部畸形次之。结论:孕妇年龄过小容易发生胎儿严重畸形,年龄过大容易发生胎儿多发畸形,且神经系统、先天性心脏畸形的机率增高,因此应加强对这类孕妇的产前超声检查,避免漏诊、误诊胎儿畸形。 |

| Abstract: |
| Objective: Analysis of the difference between fetal malformations and the age of pregnant women by the prenatal ultrasonography. Methods: 6119 cases of pregnant women were accepted prenatal ultrasonography, according to age into ≤19 years, 20 to 24 years, 25 to 29 years, 30 to 34 years, 35 to 39 years and ≥ 40 years six groups. The cases of fetal malformations which were compared with the results of prenatal diagnosis center’s examination, the postnatal newborn examination or necropsy specimens after termination of pregnancy were correct by the prenatal ultrasonography. They were analysed the six kinds of serious malformations, the number and types of fetal malformations according to various groups. Results: There were 205 cases fetal malformations in 6119 pregnant women, 186 cases were diagnosed correctly by Ultrasonography. The detection rate of six serious malformations of ≤ 19 years group was the highest. The difference was statistically significant (P< 0.05).The detection rate of Multiple malformations of ≥ 40 years was the highest. The congenital cardiac malformations was highest in the types of fetal malformations, followed by nervous system malformations, facial malformations. Conclusion: Women who are too small to be prone to be detected serious fetal malformations, women who are too old to be prone to be detected multiple malformations, and the probability of nervous system malformations and congenital cardiac malformations is higher than other pregnant women. Therefore the ultrasonic examiner should strengthen on this kind of pregnant women’s prenatal ultrasonography to avoid misdiagnosis and missed diagnosis of fetal malformations. |
