BACKGROUND
Evaluation of the cerebellum and vermis is one of the integral parts of the fetal cranial anomaly screening.
OBJECTIVES
The aim of this study was to create a nomogram for fetal vermis measurements between 17 and 30 gestational weeks.
PATIENTS AND METHODS
This prospective study was conducted on 171 volunteer pregnant women between March 2013 and December 2014. Measurements of the fetal cerebellar vermis diameters in the sagittal plane were performed by two-dimensional transabdominal ultrasonography.
RESULTS
Optimal median planes were obtained in 117 of the cases. Vermian diameters as a function of gestational age were expressed by regression equations and the correlation coefficients were found to be highly statistically significant (P < 0.001). The normal mean (± standard deviation) for each gestational week was also defined.
CONCLUSION
This study presents the normal range of the two-dimensional fetal vermian measurements between 17 and 30 gestational weeks. In the absence of a three-dimensional ultrasonography, two-dimensional ultrasonography could also be used confidently with more time and effort.
背景
小脑和蚓部的评估是胎儿颅脑异常筛查的重要组成部分。
目的
本研究的目的是创建一个孕17至30周胎儿蚓部测量的列线图。
患者和方法
本前瞻性研究于2013年3月至2014年12月对171名志愿孕妇进行。通过二维经腹超声测量矢状面胎儿小脑蚓部直径。
结果
117例获得了最佳正中平面。通过回归方程表示蚓部直径与孕周的函数关系，发现相关系数具有高度统计学意义（P < 0.001）。还定义了每个孕周的正常均值（±标准差）。
结论
本研究给出了孕17至30周二维胎儿蚓部测量的正常范围。在没有三维超声的情况下，二维超声也可以通过更多的时间和精力来可靠地使用。
