摘要
目的:探讨分析胎儿不同孕周透明隔腔宽度参考范围及其与孕周和双顶径的相关性,拟为临床提供参考依据。方法:选取2018年1月—2019年5月在郑州大学第三附属医院进行产前系统超声筛查中未发现异常的1546例不同孕周的单胎作为研究对象,采用Logistic回归分析透明隔腔宽度随孕周及双顶径的变化趋势,采用Spearman秩相关系数对透明隔腔宽度与孕周的相关性进行分析。结果:本研究透明隔腔宽度正常值参考范围为(4.64±1.32)mm;孕17~30周胎儿透明隔腔宽度与孕周存在正相关关系(r=0.63,P<0.001),孕30~37周胎儿透明隔腔宽度与孕周无显著相关性;孕19~30周胎儿双顶径与透明隔腔比值(Biparietal diameter-to-cavum septum pellucidum ratio,BCR)相对较恒定,参考范围为13.38±3.31。结论:孕17~30周胎儿透明隔腔宽度与孕周存在相关性;孕19~30周胎儿BCR较恒定。
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 2019,1546 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.
