摘要 目的探查妊娠24—26周宫颈长度及宫颈长度联合胎儿纤维连接蛋白(fFN)对早产的预测价值。方法选择1000例妊娠24—26周的孕妇,经腹部B超测量宫颈长度,其中500例联合fFN检测,对其妊娠结局进行随访。结果1000例中宫颈长度≤3cm者168例,发生早产111例(66.07%,111/168);宫颈长度〉3cm者832例,发生早产17例(2.04%,17/832),两者比较差异有统计学意义(X2=51.32,P〈0.05)。早产组宫颈长度为(2.65±0.16)cm,足月产组宫颈长度为(3.87±0.16)cm,两组比较差异有统计学意义(t=3.40,P=0.031)。只测宫颈长度的500例中宫颈长度≤3cm者87例,发生早产56例(64.37%,56/87);宫颈长度〉3cm者413例,发生早产10例(2.42%,10/413)。另500例除测量宫颈长度外,联合fFN检测,宫颈长度≤3cm者81例,其中fFN阳性者13例(均为先兆早产),发生早产55例,早产发生率为67.90%;宫颈长度〉3(3121者419例,其中fFN阳性者8例(均为先兆早产),发生早产7例,早产发生率为87.50%(7/8)。结论妊娠24—26周腹部B超测量宫颈长度对于筛选早产高危孕妇有一定的临床价值,宫颈长度≤3em者比〉3cm者更容易发生早产。对有先兆早产征象者做fFN检测非常重要,而对于无症状者做tFN检测没有必要。
