摘　　要：目的探讨产前超声检查对胎儿肢体异常的诊断价值。方法收集在我院接受孕期超声检查,并筛出胎儿肢体畸形56胎,对异常部位行三维超声检查并存储图像。结果产前超声诊断56胎肢体畸形,其中5胎失访,余51胎经引产或生产后证实共有72处畸形,其中产前超声检出64处、漏诊8处。51胎(64处)肢体异常发生的部位为:手指部分缺失4处、尺或桡骨缺失6处、裂手(足)1处、下肢羊膜和脐带缠绕致缩环1处、短肢畸形6处、左下肢完全缺如1处、下肢胫、腓骨发育不全2处,足内翻36处,双手姿势异常6处,多指(趾)1处。产前超声准确率为88.89%(64/72),漏诊率11.11%(8/72)。结论三维超声的表面成像和骨骼成像模式可明显提高胎儿肢体异常的诊断率。Objective To explore the diagnostic value of prenatal ultrasound in diagnosis of fetal limb abnormalities.Methods Totally 56 fetues with fetal limb deformities were screened out in our hospital during system screening and targeted ultrasound examination,and the images were stored.Results Among 56 fetuses with abnormal limb in pregnant women,5fetuses were lost of follow-up,and a total of 72 limb deformities were confirmed by induced labor or postpartum in 51 fetuses.Sixty tour limb deformities were diagnosed by prenatal ultrasound,and 8were missed diagnosis.A total of51 fetuses had follow-up results,which found 64 abnormal body parts：partial deficiency of finger in 4,ulnar or radial deletion in 6,crack hand（foot）in 1,a shrink ring caused by the amniotic membrane of low limb and umbilical cord winding in1,short limb malformations in 6,left leg completely absent in 1,double limbs shortness and tibia and fibula aplasia in 2,strephenopodia in 36,hands abnormal posture in 6,multi finger in 1.The accurate rate of prenatal ultrasound was 88.89%（64/72）,and the misdiagnosis rate was 11.11%（8/72）.Conclusion Three-dimensional ultrasonic surface imaging and bone imaging mode can be used to improve the diagnostic rate of fetal limb deformities.
