摘　　要：目的分析产前B超检测胎儿CSP对诊断CNS的诊断价值。方法选取324例孕周19~39周的正常胎儿为研究对象,B超测量胎儿透明隔腔(CSD)宽度,利用线性回归分析孕妇怀孕周期和CNS的关系。选取18例CSP缺如胎儿(甲组)和150例CSP正常胎儿(乙组)进行研究分析。结果由324例孕妇B超检测结果得出正常CSP宽度为(5.6±1.7)mm,线性回归分析显示胎儿CSP的宽度不受孕妇怀孕周期的影响(r=0.4,P>0.05);甲、乙2组CNS的发生率分别为100.00%、1.33%,差异有统计学意义(χ2=139.25,P<0.01)。结论 B超检测胎儿CSP宽度对产前诊断CNS具有重要诊断价值。Objective To study the clinical effect of prenatal ultrasound determining fetal cavity of septum pellucidum （CSP） on diagnosing malformations of central nervous system （CNS）.Methods A total of 324 women with gestational age between 19 and 39 weeks whose fetuses were normal were selected as study objects.We applied ultrasound to measure width of CSP and used linear-regression analysis to observe the correlation of gestational weeks with CNS malformation.We selected 18 cases with the absence of CSP as group A and selected 150 cases with normal CSP as group B to perform further study.Results Among 324 women,the normal width of CSP was defined as （5.6＆#177;1.7） mm.Linear-regression showed that the width of CSP was not affected by gestational weeks （r=0.4,P〉0.4）.The incidence rates of CNS malformation were 100% and 1.33% in group A and group B,and the difference was significant （χ2=139.25,P〈0.01）.Conclusion The width of CSP determined by ultrasound has a clinical effect on the diagnosis of CNS malformation.
