超声定位胎儿脊髓圆锥对脊柱区病变的诊断价值

摘要

Objective To determine correlation of conus medullaris in fetuses and spinal lesions through observation.Methods Retrospectively analyzing ultrasonic data of prenatal ultrasound diagnosis of fetal spina bifida(10 cases), occult cleft spine(3 cases), sacrococcygeal teratoma(3 cases), lumbar and sacral canal cyst(1 case) and 1013 cases of normal fetal, all locating conus medullaris, summarizing the sonographic features and comparing with postpartum ultrasonic.Results Spina bifida and lumbar and sacral canal cyst showed low conus medullaris position, occult cleft spine showed normal or low conus medullaris position, in cases of sacrococcygeal teratoma and the normal control group, the level of conus medullaris were normal. Conclusion Ultrasonic locating conus medullaris can provide valuable information for the diagnosis of spinal lesions, so it has important clinical value.%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。
