| 摘要 目的： 探讨胎儿肢体畸形超声特征及诊断价值。 方法： 采用连续顺序追踪法对 66342 例妊娠 12-40 周孕妇行胎儿四肢畸形筛
查。 将产前超声诊断结果与引产或产后结果进行对比分析。 结果： 发生肢体畸形 271 例， 发生率为 0.41% （ 271/66342 ） ,包括四肢短
小 5 例， 桡骨发育不全 1 例， 缺肢畸形 5 例， 足内翻 17 例， 手掌畸形 3 例， 指趾畸形 222 例及骨骼多发畸形 18 例。其中产前诊断
胎儿肢体畸形 49 例； 漏诊 222 例， 包括： 足内翻 3 例、 指趾畸形 218 例、 多发骨骼畸形 1 例。胎儿肢体畸形的出现率和产前检出率
分别为： 四肢短小 1.84% （5/271 ） 、 100% （ 5/5 ） ； 桡骨发育不全 0.36% （1/271 ） 、 100% （ 1/1 ） ； 缺肢畸形 1.84% （ 5/271 ） 、 100% （5/5 ） ；
足内翻 6.27% （ 17/271 ） 、 82.35% （ 14/17 ） ； 手掌畸形 1.10% （ 3/271 ） 、 100% （3/3 ） ； 指趾畸形 81.91% （ 222/217 ） 、 1. 8% （4/222 ） ； 多发
骨骼畸形 6.64% （18/271 ） 、 94.44% （17/18 ）。 结论： 超声对胎儿手掌、 脚掌部位以上畸形的检出率较高。 指趾畸形出现率最高， 但检
出率最低。 |

| ABSTRACT Objective:This study was to investigate the ultrasonic characteristics and its value for fetal limb deformities.
Methods:Systematic continuous sequence approach was performed to observe fetal limbs and fetal limb deformities for 66,342 cases of pregnancy
in 12-40 weeks. The prenatal diagnosis results were analyzed and compared with postnatal results. Results:Two hundred and seventy-one
cases in 66,342 fetuses occurred limb deformities (incidence rate as 0.41% ) including five cases of short limbs, one case of radial
hypoplasia, five cases of ectromelia, 17 cases of strephenopodia, 3 cases of palm deformities, 222 cases of fingers and toes deformities,
17 cases of multiple skeletal deformities. Forty-nine cases of fetal limb deformities were diagnosed by prenatal ultrasound and 222 cases
were missed including 3 cases of strephenopodia, 218 cases of fingers and toes deformities, 1 case of multiple skeletal deformities. The
frequency and prenatal detection rate of fetal limb deformities were: short limbs 1.84 % (5/271) and 100 % (5/5); radial hypoplasia 0.36
% (1/271) and 100 % (1/1); ectromelia 1.84 % (5/271) and 100 % (5/5); strephenopodia 6.27 % (17/271) and 82.35 % (14/17); palm
deformity 1.10 % (3/271) and 100 % (3/3); fingers and toes deformities 81.91 % (222/217) and 1.8 % (4/222); multiple skeletal
deformities 6.64 % (18/271) and 94.44 % (17/18).Conclusion: The detection rate of prenatal ultrasound was very high for the limb
deformities above fetal palms and soles. Fingers and toes deformities hada high incidence rate but a very low detection rate. |
