摘要
目的 探讨胎儿足内翻的声像图特征及其临床价值。方法 彩色多普勒超声检查 30 0 0例妊娠12～ 40周的胎儿。诊断足内翻畸形的标准为足底拇趾球和腓胫骨长轴切面在同一平面显示 ,不随胎儿下肢运动而改变。并将产前超声检查与胎儿尸体检查或分娩后新生儿科检查结果进行对照。结果 产前超声检查发现17例足内翻畸形 ,其中 14例合并其他复杂畸形 ,3例单纯足内翻畸形。 14例引产后尸体检查证实产前超声诊断 ,其中包括 1例胎死宫内后引产证实 ,1例产前诊断为双足内翻 ,引产后尸检为单足内翻 ;3例足月产后新生儿科检查证实 ,其中 2例假阳性。结论 胎儿足内翻畸形的声像图具有一定特征性 。
Objective To investigate prenatal ultrasound diagnosis of clubfoot and its clinical value.Methods Three thousands pregants ranging gestational age from 12 through 40 weeks were checked using Ascuson Sequoia 512 equipment.The diagnosis of clubfoot was made prospectively at the time of the scan by the following criteria: the ball of foot had to be visible in the same plane as the longitudinal section of bones of the lower leg,unchanging with fetal activity and reproducible for several images.All prenatal ultrasonographic dignoses of clubfoot were proved by autopsy or newborn physical examination.Results A total of 17 cases clubfoot fetuses were prenatal diagnosed by ultrasonography.Fourteen of 17 clubfoot fetuses had associated with complex abnormalities,three of them were isolated clubfoot.Fourteen of 17 cases with clubfoot prenatal diagnosed by ultrasound were proved by autopsy.Another three cases with clubfoot were proved by newborn physical examination,two of them were false positive diagnosis.Conclusions Prenatal diagnosis of clubfoot is reliable by ultrasound.It is helpful in diagnosis with other structural abnormalities associated with clubfoot.It can also provide direction for clinical obstetrical management.
