【摘要】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。

【Abstract 】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.
【Key words】Conus medullaris; Spinal bifida; Tethered cord; Fetus在胎儿的发育过程中, 发育初期脊髓与椎管等长, 之后脊椎管的生长速度大于脊髓, 因此脊髓下端即脊髓圆锥相对于椎管下端逐渐升高, 到28周以前已经达到较稳定水平(L2~3水平) ［1］。若各种原因使脊髓圆锥受制于椎管的末端不能正常上升, 使其位置低于正常, 即可形成脊髓栓系［2］, 由此而导致的一系列临床表现即脊髓栓系综合征, 可表现为双下肢感觉运动功能障碍及大小便失禁等, 预后较差, 因此胎儿期对其定位具有重要意义。
国内对于新生儿及小儿的脊髓圆锥末端定位大多依赖于MRI, 对于胎儿期的脊髓圆锥观察较少。本文回顾性分析到本院产前超声检查共1030例胎儿, 均对脊髓圆锥进行定位, 探讨脊髓圆锥末端位置与脊柱区病变的相关性。
