目的建立不同孕周正常胎儿小脑蚓部的正常值,并探讨其在评估小脑蚓部发育不全中的临床价值.方法采用经腹超声测量111例20～40孕周正常胎儿小脑蚓部正中矢状面的前后径(AP)和顶尾径(CC).按照上述测值对15例枕大池扩张的胎儿进行评估.结果 ①小脑蚓部AP、CC随孕周(GA)增加而增大(P＜O.05),整个妊娠过程呈线性相关(AP=-5.406+O.761 GA,r=0.97;CC=-5.795+0.783GA,r=0.973);②正中矢状断面小脑蚓部的测值和原裂、次裂、第四脑室顶部的声像图解剖特征有助于确认小脑蚓部发育畸形.结论经腹超声是确认中晚期妊娠胎儿小脑蚓部发育异常的有效诊断方法.

Objective To detect the normal values of fetal cerebellar vermis using transabdominal ultrasonography and assess its clinical significance in the diagnosis of vermal hypoplasia(agenesis). Methods A total of 111 fetuses were evaluated by transabdominal sonography between 20 and 40 weeks of gestation.The mid-sagittal antero-posterior(AP) and cranio-caudal(CC) vermian diameters were measured. A second group of 15 fetuses with cisterns magna were assessed and compared with the value of normal fetuses.0.05) and correlated linearly with gestational age ( AP = - 5.406 + 0. 761 GA, r = 0.97 ; CC = - 5.795 +fissure, second fissure and fastigium may help identify developmental anomalies. Conclusions Transabdominal ultrasonography is a valuable tool in the study of fetal vermis during the second half of pregnancy.
