| 目的：使用三维超声探讨胎儿小脑蚓部生长发育与孕周的关系,并建立相关的参考值,旨在对胎儿的小脑蚓部发育准确诊断。研究方法:使用经腹三维超声对230例18-40周正常胎儿小脑蚓部矢状面上下径,前后径和总面积进行测量,分析其与孕周的关系并建立每个孕周的相关参考值。结果：①上下径,前后径和总面积均随着孕周的增加而增加(P<0.05),线性回归方程为小脑蚓部上下径(mm)=(0.888×孕周)-10.384、小脑蚓部前后径(mm)=(0.979×孕周)-9.977、小脑蚓部面积(cm )==(0.196×孕周)-3.433。②上下径,前后径和总面积等呈偏态分布,并建立了95%参考值上限和5%的参考值下限。结论:通过建立小脑蚓部与孕周的参考值,可以帮助评估胎儿小脑生长发育过程中小脑异常的诊断。 |

| Abstract: |
| Objective: through transabdominal 3D ultrasound, fetal cerebellar vermis to investigate the relation between growth and gestational age, and related reference values were established, we study on the development of fetal cerebellar vermis diagnosis. Methods: 230 cases of 18 to 40 weeks of normal fetal sagittal diameter, anteroposterior diameter and total area,by abdominal three-dimensional ultrasound,and its relationship with gestational weeks and establish the reference values and analysis of each gestational week.Results: ①the superoinferior diameter, anteroposterior diameter and total area increased with increasing gestational age (P<0.05), and the linear regression equation for cerebellar vermis superoinferior diameter (mm) = (0.888x weeks)-10.384 , cerebellar vermis superoinferior diameter (mm) = (0.979x weeks)-9.977, cerebellar vermis area (CM) = (0.196x weeks) -3.433.②Tthe superoinferior diameter, anteroposterior diameter and total area were skewed distribution, and established the 95% reference value and the lower limit of the reference value of 5%.Conclusion: through the establishment of cerebellar vermis with gestational age reference value. This can assist in the assessment of the diagnosis of cerebellar abnormalities in the development of fetal cerebellar growth. |
