目的通过观察胎儿脊髓圆锥末端位置,确定其与脊柱区病变的相关性。方法回顾性分析本院产前超声诊断胎儿显性脊柱裂10例,隐性脊柱裂3例,骶尾部畸胎瘤3例,腰骶管内囊肿1例及1013例正常胎儿的超声资料,均定位脊髓圆锥末端位置,并与产后超声对照。结果显性脊柱裂及腰骶管内囊肿均表现脊髓圆锥低位,隐性脊柱裂脊髓圆锥可以正常也可以低位,骶尾部畸胎瘤及正常对照组脊髓圆锥位置均正常。结论超声定位脊髓圆锥末端位置对诊断脊柱区病变能提供有价值的信息,具有重要临床价值。
Objective To observe the location of the conical tip of the fetal spinal cord and determine its correlation with the lesion in the spine. Methods We retrospectively analyzed the ultrasound data of 10 cases of fetal dominant spina bifida, 3 cases of recessive spina bifida, 3 cases of sacrococcygeal teratoma, 1 case of lumbosacral cyst and 1013 cases of normal fetus, Spinal conical end position, and post-natal ultrasound contrast. Results The dominant spina bifida and lumbosacral cysts showed low conus medullaris. The recessive spina bifida spinal cones could be normal or low, and sacrococcygeal teratoma and normal condyloma acuminatum were normal. Conclusion Ultrasound localization of the conical end of the spinal cord can provide valuable information for the diagnosis of spinal lesions, which has important clinical value.
