摘要
目的评价实时三维超声在诊断胎儿体表畸形中的价值。方法采用表面成像及透明成像法对50例常规产前二维超声检查疑为胎儿体表畸形的患者行实时三维超声成像,并与引产后病理尸解结果对照,比较二维与三维超声检查与病理诊断符合率。结果50例中检出12种体表畸形,其中头颈及颜面部畸形28例,包括无脑儿4例,颈部淋巴囊肿4例,脑膜膨出3例,唇裂15例,耳畸形2例;内脏及躯干畸形9例,包括脐膨出4例,开放性脊柱裂5例;四肢畸形13例,包括四肢短小畸形5例,足内翻5例,前臂畸形1例,手畸形1例,重叠指1例。50例中48例成功获得病变部位三维立体图像,漏诊耳畸形2例。产前二维及三维超声对胎儿体表畸形判断准确率分别为70.0%(35/50)和96.0%(48/50)。结论实时三维超声成像可获得胎儿体表畸形立体图像,还可显示胎儿运动,是二维超声的重要补充,且在胎儿畸形检出率和准确性上均优于二维超声。
Objective To evaluate the diagnostic value of real-time three-dimensional ultrasound （3D-US） in the fetal surface dysplasia. Methods The fifty pregnant women suspected diagnosed with fetal surface dysplasla by routine prenatal two-dimensional ultrasound （2D-US） were examined with 3D-US by using surface and trans-maximum mode. The consistent accuracy of 2D or 3D diagnosis and pathological out- comes were compared. Results Of all, 48 cases showed successful 3D images of 12 types of surface dyspla- sia and headneck and face dysplasia 28 cases involved. Two cases of abnormal ears were misdiagnosed including 4 cases of aneneephaly, 4 cases of cystic lymphatic need, 3 cases of meningoeeles, 15 cases of clefilip, 2 cases of abnormal ears, 9 cases of viscus and trunk dysplasia including 4 omphaloeele and 5 open spinal segmentation defects and 13 cases of four-limbs dysplasia including 5 short limbs, 5 clubfoot, 1 abnor- mal forearm, 1 abnormal hand and 1 double finger . The diagnosis accuracy of the fetus surface dysplasia with prenatal 2D-US and 3D-US were 70.0% （35/50） and 96.0 % （48/50） , respectively. Conclusions The real-time 3D-US showed an fetal movement in 3D images of the fetus surface dysplasia, which is very im- portant supplement to 2D-US and superior to 2D-US in the diagnosis and fetals dysplasia with high accuracy.
