目的探讨超声检查对妊娠早、中、晚期胎儿畸形筛查的临床应用价值。方法利用B型超声对1846例孕妇进行常规产前检查。结果胎儿的畸形发生率为4.9%,多数经由手术、引产、随访证实。结论产前的超声检查对妊娠早、中、晚期胎儿的畸形筛查有很重要的临床价值,但仍然有很多畸形病例不能准确查出。同时,胎儿畸形筛查与胎儿孕周及检测医师的操作技能有密切关系。
Objective To investigate the clinical value of ultrasound in the screening of fetal malformations in early, middle and late stages of pregnancy. Methods A total of 1846 pregnant women underwent prenatal examination with B ultrasound. Results The incidence of fetal malformations was 4.9%, mostly confirmed by surgery, induction of labor and follow-up. Conclusion Prenatal ultrasound has important clinical value in the screening of fetal malformations in early, middle and late stages of pregnancy. However, there are still many abnormal cases that can not be detected accurately. At the same time, fetal malformation screening and fetal gestational age and detection of the doctor’s operating skills are closely related.
