摘　　要：选取接受产前常规二级产检超声检查的300例孕妇,均于孕晚期(28~40周)行超高频纯净波超声检查,结果显示,300例胎儿第三脑室形态主要分为似单线征14例(4.67%)、平行线征265例(88.33%)、“V”形征21例(7.00%);第三脑室宽径、前后径与孕妇孕周、双顶径均呈正相关关系(P<0.05);300例孕妇第三脑室宽径、前后径95%参考值分别为1.21~1.64 mm、10.00~10.41 mm。提示采用超高频纯净波超声对孕晚期胎儿第三脑室进行测量,有助于获取更清晰脑室形态与测量数据,为临床产前中枢神经系统畸形诊断与筛查提供重要参考手段。A total of 300 pregnant women in our hospital who underwent routine antenatal secondary obstetric ultrasound examination were selected,all of whom underwent ultra-high frequency pure wave ultrasound examination at 28-40 weeks in the third trimester.The results showed that the morphology of the third ventricle of 300 fetuses was divided into 14 cases(4.67%)with similar single-line sign,265 cases with parallel line sign(88.33%),and 21 cases with“V”sign(7.00%).The width and anteroposterior diameter of the third ventricle were positively correlated with the gestational age and biparietal diameter of pregnant women(P<0.05).The 95%reference values of the width and anteroposterior diameters of the third ventricle of 300 pregnant women were 1.21-1.64 mm and 10.00-10.41 mm,respectively.It is suggested that the use of ultra-high frequency pure wave ultrasound to measure the third ventricle of the fetus in the third trimester of pregnancy is helpful to obtain clearer ventricle morphology and measurement data.It can also provide an important reference for clinical prenatal diagnosis and screening of central nervous system malformations.
