摘　　要：目的探讨超声筛查诊断胎儿肢体畸形的价值。方法超声筛查8 368名孕16-34周的孕妇,运用二维连续顺序追踪超声检测法（SCSA）结合三维超声表面及透明成像模式检查胎儿肢体。结果引产后胎儿肢体畸形22例,产前超声检出21例[9例双足内翻,1例一足外翻,2例四肢短小畸形,1例左小腿缺如,1例双上肢前臂缺如,3例肢体姿势异常,1例双侧桡骨缺失,3例多指（趾）]。其中19例合并其他畸形,1例漏诊及3例部分漏诊。结论二维超声连续顺序追踪检测法结合三维超声表面及透明成像法是产前检出胎儿肢体畸形的有效方法。Objective To evaluate the effectiveness of ultrasound screening and diagnosis of fetal limb defor-mities. Methods Ultrasound screening of 8 368 cases of pregnancy 16 to 34 weeks pregnant , focus on detection of fetus′limbs by using systematic continuous sequence approach （SCSA） combined with three-dimensional ultrasound. Results After development of fetal limb deformity in 22 cases, prenatal ultrasound detected 21 cases, including 9 cases of varus feet,1 case of valgus foot , 2 cases of short limb deformity, 1 case with left leg absent,1 case of upper forearm absent, 1 cases of pairs of limb posture abnormalities, 3 cases of pairs of limb posture abnormalities, 1 case of Congenital radiu deficiency ,and 3 cases of multiple fingers （toes）, with 19 cases complicate with other malformations,1 case of missed diagnosis and missed parts of 3 cases. Conclusion The method of systematic continuous sequence ap-proach （SCSA） in two-dimensional ultrasound combined with three-dimensional ultrasound screening are effective tools for use in prenatal identification ofetal limb deformities.
