Abstract Objective: To investigate the reference range of the width of fetal cavum septum pellucidum(CSP) at different gestational age and its correlation with gestational age and biparietal diameter, intending to provide a reference basis for clinic. Methods: From January 2018 to May 2019, 1 546 cases of singleton pregnancy without abnormality were collected from the third affiliated hospital of Zhengzhou university for the prenatal ultrasound screening at different gestational age. Logistic regression analysis was used to analyze the change trend of the width of CSP with gestational age and biparietal diameter, Spearman rank correlation coefficient was used to analyze the correlation between the width of CSP and gestational age. Results: In this study, the normal reference range of CSP width was (4.64±1.32) mm, there was a positive correlation(r=0.63, P<0.001) between CSP width and gestational age at 17 to 30 weeks, and there was no significant correlation between CSP width and gestational age at 31 to 37 weeks, the fetal biparietal diameter-to-cavum septum pellucidum ratio(BCR) at 19 to 30 weeks was relatively constant and the reference range was 13.38±3.31. Conclusion: The CSP width is related to the gestational age at 17 to 30 weeks, the BCR is relatively constant at 19 to 30 weeks.
