Analysis of 56 CASES: 56 cases of polyhydramnios, which were diagnosed sonographically over a period of three years, were analysed retrospectively in this study. In 9334 births, the prevalence of this symptom was 0.6%. Malformations were the most common cause (26.7%) of polyhydramnios (p < 0.001). In comparison to our normal patient group gestational diabetes, twin pregnancies with elevated amniotic fluid of one twin, virus infections, fetal chromosome abnormalities were diagnosed at a significantly higher rate (p < 0.001). The perinatal mortality rate (28.5%) in comparison to our normal collective (1.6%) was also significantly higher. Because of the high mortality, polyhydramnios must be assessed precisely and treated if possible. Fetal karyotyping should be routinely performed in the second trimester.
56例病例分析：本研究回顾性分析了三年间超声诊断的56例羊水过多病例。在9334例分娩中，该症状的患病率为0.6%。畸形是羊水过多最常见的原因（26.7%）（p<0.001）。与我们的正常患者组相比，妊娠糖尿病、一个胎儿羊水过多的双胎妊娠、病毒感染、胎儿染色体异常的诊断率显著更高（p<0.001）。与我们的正常人群（1.6%）相比，围产期死亡率（28.5%）也显著更高。由于死亡率高，必须对羊水过多进行精确评估并尽可能进行治疗。孕中期应常规进行胎儿核型分析。
