分时段系统超声检查对筛查胎儿畸形的临床意义

Clinical significance of the stage system ultrasonography for screening the fetal deformity

目的探讨分时段系统超声检查对筛查胎儿畸形的临床价值。方法根据胎儿生长发育特点,对12380例孕11～40周的胎儿进行分时段系统超声筛查,对畸形胎儿作出诊断。结果12380例胎儿中,经产后证实胎儿畸形223例,产前超声筛查诊断胎儿畸形212例,检出率95.07%,漏诊11例,漏诊率4.93%。结论分时段系统产前超声筛查,能较清晰地显示胎儿各时期的形态结构,是产前及时发现胎儿畸形,及时终止妊娠,确保出生质量的重要手段。

Objective To determine the clinical significance of the stage system ultrasonography（SSUS） for screening the fetal de- formity. Methods According to the prenatal growth and development characteristics of the fetus, 12,380 pregnant women with gestational age of 11-40 weeks underwent SSUS. Results Among 12,380 fetus whose mother underwent SSUS during different periods of the gestation, total 223 fetus were demonstrated to have various deformities after birth, of whom, 212 fetus with deformity were detected by prenatal SSUS. The detection rate of fetal deformity in the group was 95.07 % but 11 cases were leak-diagnosed, thus the leak-diagnostic rate was 4.93 %. Conclusion The prenatal SSUS can clearly visualize the fetal shape and strueture at different periods and therefore it is an important means for timely find the fetal deformity, timely terminate the pregnancy and precisely ensure the birth quality.
