目的分析并探讨彩色多普勒超声应用于11~14周胎儿筛查的价值。方法选取2012年3月~2014年9月收治于我院的2060例孕周为11~14周的孕妇作为研究对象,应用彩色多普勒超声对其进行胎儿筛查,记录检查数据,进行统计学分析。结果果胎儿总数为2060例,单胎1980例,双胎80例,对2060例胎儿进行彩色多普勒超声筛查,胎儿疑似异常例数为20例,其中6例胎儿颈项透明层(NT)≥3.0mm;7例胎儿NT≥3.0mm合并其他异常;1例胎儿静脉导管血流频谱异常;6例胎儿单纯解剖结构异常,具体为2例胎儿出现中枢神经系统畸形(无脑儿1例,露脑畸形1例),1例胎儿出现脉络丛囊肿,1例胎儿出现胎盘部分性葡萄胎,1例脐带膨出,1例多发畸形。结论对11~14周胎儿行高清彩色多普勒超声检测,可及时发现胎儿异常,提供重要的遗传学信息,为临床诊疗提供可靠依据。
Objective To analyze and discuss the value of color Doppler ultrasonography in fetal screening for 11-14 weeks. Methods From March 2012 to September 2014, 2060 pregnant women with gestational weeks of 11 to 14 weeks who were admitted to our hospital from March 2012 to September 2014 were enrolled in this study. Their fetuses were screened by color Doppler sonography and their data were recorded and statistically analyzed Analysis. Results The total number of fetuses was 2060, 1980 singletons and 80 twins. 2060 fetuses were screened by color Doppler ultrasonography. There were 20 fetuses with suspected anomalies, of which 6 were fetal NT, 7 cases fetus NT≥3.0mm with other abnormalities; 1 case of fetal venous catheter blood flow abnormalities; 6 cases of simple anatomy of the fetus, specifically 2 cases of fetal central nervous system malformations (no brain anemia in 1 case, 1 case of dendritic deformity), one case had choroid plexus cyst, one case had partial placental mole, one case had umbilical cord bulging and one case had multiple deformities. Conclusion High-definition color Doppler ultrasound examination of fetuses from 11 to 14 weeks can detect fetal abnormalities in time, provide important genetic information and provide reliable evidences for clinical diagnosis and treatment.
