摘要
目的：应用超声对晚孕期胎儿和新生儿透明隔腔（CSP）的监测,评价其临床意义。方法：随机选择晚孕期（35～38周）无异常发现孕妇80例,除常规超声检查胎儿外,重点观察胎儿头颅,取横断面,部分胎儿可观察到矢状面和冠状切面。出生后1～14天新生儿130例,新生儿缺血缺氧性脑病（HIE）或早产儿80例和正常足月新生儿50例,经超声或CT或MRI检查。结果：晚孕期（孕35～38周）超声测量CSP正常宽度为6±2.64,CSP的存在是胎儿脑中线结构发育良好的标志。正常足月新生儿出生后即闭合者占84%,只有16%可见CSP。而早产儿或足月儿伴发HIE者CSP发生率为85%。结论：CSP是胎儿的正常脑内结构,足月新生儿大部分闭合,而HIE或早产儿大部分CSP增宽,透明隔腔增宽是新生儿脑组织有病变或发育不全的佐证。
Objective：To evaluate the clinical value of the cavum sepri pellucidi（CSP） of the fetus fof the third trimester （ 35 ～ 38 weeks） and neonate using ultrasonography.Methods： In 80 randomized pregnant women （35 ～ 40 weeks）,the fetal heeds were observed onespeeiaUy transverse plane, partly on sagittal or coronary plane besides fetal routine ultrasonography. 80 cases with hypoxic ischemic encephalopathy （HIE） or premature and 50 cases of full-term nawbom infants were examined with US, CT or MRI in 130 neonates of 1 ～ 14 days.Results：The normal width of the CSP of the fetus was 6±2.64mm during 35 ～ 38 weeks gestation, the incidence rate of CSP inthe full-term newborn infant was 16%. line incidence rate of CSP of HIE or premature was 85%. Conclusion： The CSP is the fetal normalstructure in the brain, but in the most of full-term newborn it is dosed. The CSP in HIE or premature new born is widened, it is an evidence of brain pathological changes and underdevdopment.
