【摘要】：目的:探讨二维超声联合四维超声对不同孕周产前超声筛查胎儿畸形的临床价值。方法:选择本院2010年1月~2012年11月就诊的不同孕周孕妇进行阶段性超声筛查,分为孕早期(11~17+6周)、孕中期(18~27+6周)、孕晚期(28~40+6周)。对所有不同孕周的孕妇首先接受二维超声诊断检查,对初步怀疑胎儿畸形的孕妇再次实施二维超声联合四维超声检查,将不同孕周的二维超声检查结果以及联合四维超声检查与临床分娩结果分析比较。结果:2891例孕妇共分娩出2930例胎儿,经临床观察和随访发现124处畸形,其中泌尿生殖系统35处,消化系统31处,心脏23处,胸腹腔积液14处,胎儿肿瘤8处,皮肤水肿8处,四肢骨折5处。孕中期胎儿畸形检出率较高,且以泌尿生殖系统和消化系统为主,二维超声联合四维超声对不同孕期的胎儿畸形的临床诊断准确率显著高于单纯二维超声诊断准确率(P0.05)。结论:孕早期超声可对部分严重的胎儿畸形进行早期诊断,孕中期超声可筛查出部分胎儿结构异常,孕晚期超声则可提高迟发型胎儿畸形诊断检出率。超声检查时产前胎儿畸形检查的重要手段,二维超声联合四维超声检查可以显著提高胎儿畸形诊断率,是及时发现胎儿异常、降低出生缺陷的首选方法,应根据不同孕周的超声特点,提高检出率,为临床诊断提供可靠的参考。
[Abstract]:Objective: to investigate the clinical value of two-dimensional ultrasound combined with four-dimensional ultrasound in prenatal ultrasound screening of fetal malformation in different gestational weeks. Methods: the pregnant women with different gestational weeks in our hospital from January 2010 to November 2012 were selected for phase ultrasound screening, which were divided into early pregnancy (1117 weeks), middle pregnancy (1827 weeks), and late pregnancy (2840 6 weeks). All pregnant women of different gestational weeks were first examined by two-dimensional ultrasound, and pregnant women who were initially suspected of fetal malformation were again examined with two-dimensional ultrasound and four-dimensional ultrasound. The results of two-dimensional ultrasound and four-dimensional ultrasound in different gestational weeks were compared with the results of clinical delivery. Results 2930 fetuses were born to 1: 2891 pregnant women. Clinical observation and follow-up revealed 124 malformations, including 35 genitourinary system, 31 digestive system, 23 hearts, 14 hydrothorax and peritoneal effusion, 8 fetal tumors and 8 skin edema. Five fractures in the limbs. The detection rate of fetal malformation in the second trimester was higher than that in simple two-dimensional ultrasound (P0.05). Conclusion: early ultrasound can be used to diagnose some severe fetal malformations, second trimester ultrasound can screen out some fetal structural abnormalities, and late pregnancy ultrasound can improve the detection rate of delayed fetal malformation. Two-dimensional ultrasound combined with four-dimensional ultrasound can significantly improve the diagnostic rate of fetal malformation, which is the first choice to detect fetal abnormalities and reduce birth defects in time. According to the characteristics of different gestational weeks, we should improve the detection rate and provide reliable reference for clinical diagnosis.
