【摘要】：目的建立超声检测不同孕期胎儿脊髓圆锥末端至最末尾骨远端距离的正常值,评估其在脊髓拴系诊断中的价值。方法研究对象包括400例正常胎儿及8例脊髓拴系的胎儿。随机选择40例胎儿,进行医师内及医师间测量结果的信度分析。建立胎儿脊髓圆锥末端至最末尾骨远端距离的正常值范围,比较正常组及脊髓拴系组的差别。结果 (1)400例胎儿中,脊髓圆锥末端至最末尾骨远端的显示率为91%。(2)相同及不同医师测量的重复性良好(ICC:0.990~0.998),其95%一致性界限分别为:-2.2~2.6mm和-3.7~3.1mm。(3)胎儿脊髓圆锥末端至最末尾骨远端距离与孕周呈线性正相关关系,相关方程为:脊髓圆锥末端至最末尾骨远端距离=-23.09+2.39孕周(r=0.965,P0.001)。(4)8例脊髓拴系组的脊髓圆锥末端至最末尾骨远端距离与正常组相比明显缩短(P0.001)。结论超声测量胎儿脊髓圆锥末端至最末尾骨远端距离简便可行,这一参数有助于产前诊断胎儿脊髓拴系。
[Abstract]:Objective to establish a normal value of the distance from the end of the spinal cord cone to the distal end of the tail bone in fetuses during different pregnancy by ultrasound. Methods the study included 400 normal fetuses and 8 cord tethered fetuses. Forty fetuses were randomly selected. To establish the normal range of the distance from the end of the fetal spinal cord cone to the distal end of the tail bone, and to compare the difference between the normal group and the tethered cord group. The display rate of the end of the spinal cone to the distal end of the tail bone was 91. 2) the reproducibility measured by the same and different doctors was good. The 95% consistency limit of ICC: 0. 990 and -3. 710. 6 mm and-3. 731 mm. 3 respectively) the distance from the end of the spinal cord cone to the distal end of the tail bone was positively correlated with the gestational week, and the correlation between the distance between the end of the spinal cord cone and the distal end of the tail bone was positively correlated with the gestational age. The correlation equation is as follows: the distance from the end of the spinal cord cone to the distal end of the tail bone is 23.09 2.39 weeks of gestational age 0.965U 0.965g P 0.001N. The distance from the end of the spinal cord cone to the distal end of the tail bone in the tethered cord group is significantly shorter than that of the normal group. Conclusion Ultrasound measurement of fetal spinal cord circle is a significant reduction of the distance from the distal end of the cone to the distal end of the tail bone compared with the normal group. The distance from the end of the cone to the distal end of the tail bone is simple and feasible. This parameter is helpful for prenatal diagnosis of fetal tethered cord.
