目的 探索胎儿脑-胎盘率(cerebro-placental ratioCPR)预测胎儿宫内发育迟缓(Intra uterine growth restrictionIUGR)胎儿不良妊娠结局的价值。方法 回顾分析201371日至201671日在广东省妇幼保健院超声诊断科行级产前超声检查诊断为胎儿宫内发育迟缓胎儿的CPR值,以CPR1.08为异常,探索其对IUGR胎儿围产期发病率、死亡率、出生体重、阿普加评分、新生儿并发症等不良妊娠结局预测价值。结果 211例研究对象中,共有111例(52.3%)研究对象表现出至少1种不良胎儿结局。CPR1.08预测小于胎龄儿(IUGR10%)的灵敏度为75%,特异度为63%,阳性预测值为69%,阴性预测值为69%ROC曲线AUC74%。对早发性IUGRCPR1.08预测小于胎龄儿(34)IUGR10%)的灵敏度为87%,特异度为43%,阳性预测值为83%,阴性预测值为50%ROC曲线AUC80%结论 CPR异常可作为IUGR高风险胎儿,尤其是早发性IUGR胎儿围产期结局的潜在指标,对IUGR胎儿不良妊娠结局有预测作用。

Objective The purpose of this study was to detect the impact of using the cerebro-placental Doppler ratio (CPR) in the prediction of adverse perinatal outcomes in growth-restricted pregnancies. Methods A retrospective cohort study of cases of intrauterine growth restriction over a 3-year period was conducted. The umbilical artery and middle cerebral artery pulsatility indices were converted to CPRs. The CPR of less than 1.08 was used in predicting adverse outcomes. Adverse perinatal outcomes evaluated included cesarean delivery for fetal distress, 5-minute Apgar scores less than 7.0, intraventricular hemorrhage, respiratory distress syndrome, and perinatal death. Results In 211 pregnancies meeting our inclusion criteria, there were111 with at least 1 adverse outcome. With the use of a CPR ratio less than 1.08, the sensitivity, specificity, and positive and negative predictive values for predicting an adverse outcome were 75%, 63%, 69%, and 69%, respectively; area under the receiver operating characteristic curve, 0.74). With a CPR threshold of less than 1.08 for cases with IUGR at less than 34weeks, the sensitivity, specificity, and positive and negative predictive values were 87%, 43%, 83%, and 50%; area under the receiver operating characteristic curve, 0.80).Conclusions An abnormal CPR is associated with adverse perinatal outcomes in growth-restricted fetuses, especially with IUGR at less than 34 weeks.
