目的:探讨超声对CSP异常的诊断价值及其在产前遗传咨询及围产儿结局中的临床意义.方法:纳入2009年3月至2012年6月在本院产前超声检查的胎儿,在丘脑水平横切面显示透明隔腔,测量其宽度,测量标准:≥10mm者为增宽,≤2mm者为偏小,未显示或显示不清者为缺如.检查确定为CSP异常者再对胎儿进行全面扫查,以仔细检测有无其他颅内结构异常,进行详细的记录.对透明隔腔异常者进行随访,比较不同类型的透明隔腔异常者的围产儿结局.结果:超声共诊断胎儿透明隔腔异常病例124例,发生率为0.3％.超声诊断透明隔腔缺如者59例,其中14例为胼胝体发育不全,12例为全前脑,均立即终止妊娠;8例为孤立性透明隔腔缺如,9例MRI显示透明隔腔及其它颅内结构正常,生后均未见明显异常;16例因伴发畸形引产未进一步检查.超声诊断透明隔腔增宽者43例,其中13例为第五、六脑室扩张,20例孤立性透明隔腔增宽,生后均未见明显异常;10例因伴发畸形引产未进一步检查;超声诊断透明隔腔偏小者22例,其中1例为胼胝体发育不全,立即终止妊娠;18例孤立性透明隔腔偏小者生后未见明显异常;3例因伴发畸形引产未进一步检查.
