超声连续顺序追踪法在胎儿肢体畸形中的诊断价值

The ultrasonographic effectiveness of SCSA in the prenatal diagnosis of fetal limb deformities

目的探讨超声连续顺序追踪法（SCSA）诊断胎儿肢体畸形的价值。方法运用彩色超声多普勒诊断仪对2008年1月至2012年4月期间的41460例中晚孕行SCSA检查胎儿肢体，并与出生或引产后胎儿肢体畸形的大体标本相对照。结果41460例胎儿中有肢体畸形99例，其中常规超声检查股骨异常者31例，SCSA发现胎儿肢体畸形92例。19～〈27孕周SCSA共检出胎儿肢体畸形68例，占所有检出肢体畸形的73．91％。肢体畸形种类繁多，其中足内翻畸形最为常见（27例），其次为四肢短小畸形（24例），之后依次为肢体复合畸形（11例）、肢体姿势异常（10例）、部分截肢（10例）、多指／趾畸形（7例）。结论SCSA是产前筛查胎儿肢体畸形的有效方法，能及早发现胎儿肢体畸形及其类型。

Objective To explore the value of ultrasonographic on fetal limb deformities in prenatal diagnosis by using systemat- ic continuous sequence approach（SCSA） Methods During the period of January 2008 to April 2012,SCSA with color doppler ultra- sonography was used to screen 41 460 pregnant women in order to observe the four limbs of the fetus. And compared with the linabs of the fetus after birth or induction of labor. Results There were 99 cases of fetal limb deformities in 41,460 pregnancy,of which 31 cases of femoral abnormalities were found by routine ultrasound, 92 cases of fetal limb deformities were found by SCSA. 68 cases of fetal limb deformities were detected by SCSA in 19--~27 weeks of gestation, accounting for 73.91 ~ of detection limb deformi ties. In the 99 cases of fetal limb deformities,varus feet were the most was（27 cases） ,followed by short limbs deformity（24 cases）, limbs compound malformations（11 cases）,limb posture abnormalities（10 cases）, part of the amputation（10 cases） and multiple fin- gers/toes（7 cases）. Conclusion SCSA with color doppler ultrasonography is an effective method for prenata screening of fetal limb deformities.
