胎儿隐性脊柱裂及超声诊断

作者:练丹;黎烨; 刊名:华夏医学 上传者:黄长祥

【摘要】隐性脊柱裂常无症状,它常伴发脊髓栓系综合征及局部皮肤异常,隐性脊柱裂是否伴发脊髓低位、脊髓栓系等畸形明显影响着疾病的预后.超声定位脊髓圆锥位置及有无半锥体有助于发现胎儿隐性脊柱裂.常规2维超声通常只对胎儿脊柱结构进行断面观察,但胎儿4维实时超声对定位胎儿脊髓圆锥可以作为发现和诊断隐性脊柱裂的重要信号标志.笔者对胎儿隐性脊柱裂的超声诊断进展进行综述.

It is often associated with tethered cord syndrome and local skin abnormalities,and whether occult spina bifida is associated with a low level of spinal cord or tethered spinal cord significantly affects the prognosis of the disease. Ultrasound positioning of the spinal cord cone and the presence of semi-conical is helpful for the discovery of the occult spina bifida. The conventional 2 dimensional ultrasound is usually only used to observe the structure of the fetal spine.However,the fetal 4 dimensional real time ultrasound can be used as an important signal sign for the diagnosis of spina bifida. In this paper,the progress of ultrasound diagnosis of fetal spina bifida is reviewed. Key words: occult spina bifida; ultrasound; spinal cord cone; 4 dimensional real time ultrasound 胎儿脊柱裂是胎儿神经系统的常见畸形之一, 其分类较
