【摘要】 目的探讨产前胎儿颅脑超声检查中透明隔腔(CSP)的临床意义。方法采用双顶径切面对1 500例胎儿(孕龄18～40周)的CSP宽度进行测量,分析CSP宽度与孕周的相关性及检出的CSP异常胎儿的声像图表现。结果 CSP的显示率为94.73%(1 421/1 500),CSP宽度为(0.65±0.17)cm,与胎儿孕周无显著相关性(P>0.05)。CSP异常胎儿包括胼胝体缺失合并单心室1例、前脑无裂畸形1例、重度脑积水2例。结论 CSP是胎儿颅脑超声检查的常规内容,对检出畸形具有重要意义。CSP缺如常伴发一些胎儿颅脑畸形;CSP异常扩张与透明隔囊肿、透明隔血肿等相关。更多还原

【Abstract】 Objective To evaluate the clinical significance of cavum septum pellucidum(CSP)with prenatal fetal brain ultrasonography.Methods The width of CSP in 1500 fetus(gestational ages from 18 weeks to 40 weeks)was measured in bipareital diameter view.The correlation between CSP width and gestational ages was analyzed.The ultrasonographic appearance of fetus with abnormal CSP was analyzed.Results CSP could not be visualized in 79 fetus and the visualization rate of CSP was 94.73%(1421/1500).The width of CSP was(0.65+0.17)cm.There was no significant correlation between CSP width and gestational ages (P>0.05).4 cases with abnormal CSP were detected,which included 1 agenesis of the corpus callosum and single ventricle,1 holoprosencephaly and 2 severe hydrocephalus. Conclusions CSP is a routine index in fetal brain uhrasonography,which is of great importance in scanning fetal deformities.The absence of CSP is often accompanied with some brain abnormalies.Some fetal brain abnormities,such as CSP cyst and hematoma in CSP,are often correlated with enlarged CSP.更多还原
