摘要
目的探讨运用超声检查的二维模式结合三维成像的骨骼模式、VCI模式观察胎儿脊髓圆锥的位置及其形态对胎儿隐性脊柱裂的诊断价值。方法选取2013年1月至2015年12月行产前系统筛查孕妇51 896例,运用多模式超声成像技术分析产前超声提示隐性脊柱裂胎儿6例的脊髓圆锥位置及其形态的变化声像图,且经产后高频超声检查或出生后MRI证实。结果 6例隐性脊柱裂胎儿中产前超声均发现其脊髓圆锥位置明显低于肾盂水平,失去正常的"鼠尾状"形态,其中1例合并软腭裂(产前漏诊)。产前超声胎儿脊髓圆锥位置及其形态100%可以显示。结论产前多模式超声成像技术是观察胎儿脊髓圆锥位置及其形态的首选方法,它能够提供重要的有价值的信息。
Objective To analyze two-dimensional ultrasonography and three-dimensional ultrasound with skeletal pattern and VCI pattern in the observation of position of conus medullaris as well as diagnostic value of their shapes on fetal spina bifida occulta.Methods 51 896 gravidas who underwent prenatal screening during January,2013 to December,2015 were selected,and multi-mode ultrasound imaging technique was used to analyze changes of the position and morphology of conus medullaris in 6 cases of fetal spina bifida occulta which showed by prenatal ultrasound,and they were confirmed by high fre-quency ultrasonography or MRI after delivery.Results Prenatal ultrasound showed that position of conus medullaris of the 6 cases of fetal spina bifida occulta were all significantly lower than pelvis level,losing the normal form of“rat tail”,and one cases was complicated with soft palate cleft（missed prenatal diagnosis）.The position and morphology of the conus medullaris could be showed by prenatal ultrasound in 100%.Conclusion Prenatal multi-mode ultrasound imaging is the first choice for the observation of the position and the shape of the conus medullaris,it can provide valuable information.
