摘　　要：目的观察产前超声检查对胎儿畸形的诊断作用及影像学特点分析。方法选取2017年7月至2018年7月我院接受产前超声检查孕妇1550例,胎儿上下肢长骨应用连续顺序追踪超声法(SCSA)检查,加用弧形扫查法检查胎儿手足,胎儿肢体形态、运动、姿势、结构等动态观察。完成系统性超声检查后,使用三维成像对胎儿畸形部位或可疑部位检查,分析产前超声胎儿畸形诊断结果。结果本组1550例产前超声孕妇中,经出生后或引产证实53例胎儿畸形;产前超声检出49例(92.45%),漏诊畸形儿4例(7.55%);4例漏胎儿畸形中,1例隐性脊柱裂、2例多指、1例足内翻;超声检查49例患儿中,肢体异常9例、腹壁裂5例、脐膨出4例、致死性侏儒3例、脊柱裂5例、无脑儿2例、唇裂5例、心脏畸形9例、消化道闭锁3例、单侧肾缺如4例。结论使用超声进行产前检查,具有可重复性高、无痛、安全、简便,且对胎儿畸形检出率高;但胎儿手足姿势、末端指(趾)数目易发生漏诊,产前应重点检查。Objective To observe the diagnostic value and imaging characteristics of prenatal ultrasound examination for fetal malformation.Methods From July 2017 to July 2018,1550 pregnant women underwent prenatal ultrasound examination.The long bones of fetal upper and lower limbs were examined by continuous sequential ultrasound(SCSA),and the shape and movement of fetal hands and feet,fetal limbs and limbs were examined by arc scanning.Posture,structure,etc dynamic observation.After systemic ultrasound examination,three-dimensional imaging was used to examine the fetal deformities or suspicious sites,and the results of prenatal sonographic diagnosis of fetal malformations were analyzed.Results Among the 1550 pregnant women with prenatal ultrasound,53 cases of fetal malformation were confirmed by postnatal or induced labor,49 cases(92.45%)were detected by prenatal ultrasound,4 cases(7.55%)were missed diagnosis of abnormal fetus,1 case of abdominal wall fissure,2 cases of multiple fingers and 1 case of foot varus were found in 4 cases of fetal leakage.There were 9 cases of abnormal limbs,5 cases of abdominal wall bifida,4 cases of umbilical cord protrusion,3 cases of fatal dwarfism,5 cases of spinal bifida,2 cases of anencephaly,5 cases of lip,9 cases of heart malformation,3 cases of alimentary tract atresia,4 cases of unilateral renal obstruction.Conclusion The prenatal examination with ultrasound is highly repeatable,painless,safe,simple,and has a high detection rate for fetal deformities,but fetal hands and feet.Posture,the number of terminal fingers(toes)easy to miss diagnosis,antenatal should focus on examination.
