摘　　要：目的了解胎盘提前老化的超声征象与妊娠结局的关系。方法回顾性分析30例妊娠37周前超声观察到Ⅲ级胎盘成熟度的单胎妊娠产妇的妊娠结局,并随机抽取同期154例足月后观察到Ⅲ级胎盘成熟度的单胎产妇的资料作为对照。结果胎盘提前老化组的孕龄为(37.38±2.10)周,新生儿出生体质量为(2 802.00±502.99)g,显著小于对照组[(39.48±2.44)周和(3 324.35±411.34)g,P<0.001],羊水过少发生率(26.67%)和择期剖宫产率(96.67%)显著高于对照组(6.49%和48.36%,P<0.05)。结论胎盘提前老化的超声征象与羊水过少和新生儿低出生体质量,可能提示胎盘功能减退,应密切监护。Objective To explore the association between placental premature aging observed ultrasonographically and the pregnancy outcome. Method The perinatal outcome of 30 pregnant women with grade III placenta observed ultrasonographically before 37 weeks of gestation were analyzed retrospectively, with 154 pregnant women with grade Ⅲ placenta at full term (>37 weeks) selected at random to serve as the control. Result The gestational age at delivery (37.38±2.10 weeks) and newborn birth weight (2 802.00±502.99 g) in cases of placental premature aging were significantly lower than those in the control group (39.48±2.44 weeks and 3 324.35±411.34 g, P<0.001), and the incidence of oligohydramnios (26.67%) and rate of cesarean delivery (96.67%) were significantly higher than those in the control group (6.49% and 48.36%, P<0.05). Conclusion The ultrasonographic signs grade Ⅲ placenta maturation before 37 weeks of gestation is associated with oligohydramnios and low birth weight and might help predict placental dysfunction, which needs close monitoring for the benefits of the mother and fetus.
