18-三体综合征胎儿孕中期超声表现分析

目的:分析18-三体综合征胎儿的中孕期超声表现,探讨其在产前诊断中的作用。方法:对2006年1月～2011年3月在广西壮族自治区妇幼保健院经产前诊断发现的32例中孕期18-三体综合征胎儿进行回顾性分析。结果:32例18-三体综合征胎儿均具有各种不同的高危因素,其中31例有超声异常发现(96.9%),最多见的超声异常为:心脏畸形(50.0%)、肢体畸形(43.8%)、脉络丛囊肿(40.6%)、宫内发育迟缓(37.5%);29例(90.6%)18-三体综合征胎儿可检出两项及以上超声异常,18例(56.3%)可检出4项及以上超声异常。结论:绝大部分的18-三体综合征胎儿中孕期可发现超声异常并以多项异常为主,超声系统检查是最有效的18-三体综合征胎儿产前筛查方法,对胎儿进行中孕期超声系统检查并结合各种高危因素进行综合评价,可减少不必要的侵入性检查。
