超声诊断单纯性羊水过多的临床意义

The clinical significance of ultrasonography in the diagnosis of simple polyhydramnios

目的探讨超声诊断单纯性羊水过多的临床意义。方法以二维半定量法将该院住院及门诊首次超声诊断单纯性羊水过多的186例单胎孕妇分为3组:单独羊水指数(AFI)≥20cm(A组)、单独最大羊水池深度(AFV)≥8cm(B组)、AFI≥20cm且AFV≥8cm(C组),并动态监测其变化。结果 C组中持续性羊水过多较其他两组发生率高,胎儿畸形发生率亦较其他两组发生率高,差异均有统计学意义(P<0.05);3组中未发现复发性羊水过多与胎儿畸形有相关性(P>0.05);84.4%的单纯性羊水过多未发现胎儿畸形。结论超声诊断单纯性羊水过多对评价胎儿畸形、宫内转归及预后具有一定的临床价值,利于产前咨询及处理。

Objective To investigate the clinical significance of ultrasonography in the diagnosis of simple polyhydramnios . Methods 186 singleton pregnancies cases of inpatient and outpatient diagnosed with simple polyhydramnios were divided into three groups with a two-dimensional semi-quantitative method ,separate amniotic fluid index （AFI）〉 20cm （A group） ,separate maxi-mum amnionic fluid volume（AFV）〉8 cm（B group） ,AFI≥20 cm and AFV≥8 cm（C group） ,and the changes were dynamically monitored .Results Occurrence rates of persistent polyhydramnios and fetal malformations in C group was higher than in the other two groups ,and the difference showed no statistical significance（P〈0.05）;No correlation was found between recurrent polyhydr-amnios and fetal malformation among these three groups（P〉0.05）;Among the 84 .4% of simple polyhydramnios ,no fetal malfor-mation was found .Conclusion Ultrasound diagnosis of simple polyhydramnios shows clinical value in assessment of fetal malfor-mation ,fetal outcome ,perinatal morbidity and prognosis ,and is good for prenatal counseling and treatment .
