The diagnostic value of color Doppler ultrasound combined with placental volume measurement for fetal growth restriction
目的:探究彩色多普勒超声联合胎盘体积(PV)检测对胎儿生长受限(FGR)的诊断价值.方法:回顾性选取2023年3月—2025年2月我院收治的105例单胎产妇为研究对象,根据是否发生FGR分为FGR组(n=46)与非FGR组(n=59),比较两组产妇临床资料,收集产妇超声参数与PV资料,采用多因素Logistic回归分析FGR的影响因素,并采用ROC曲线分析超声参数与PV对FGR的诊断价值.结果:两组产妇年龄、BMI、孕周、孕次、产次均无统计学差异(P＞0.05),但FGR组新生儿体质量明显低于非FGR组(P＜0.05).FGR组胎儿脐动脉(UA)血流参数收缩期末流速与舒张期末流速比值(S/D)、阻力指数(RI)以及搏动指数(PI)均明显更高;且FGR组PV明显小于非FGR组(P＜0.05).FGR组胎儿大脑中动脉(MCA)血流参数RI、PI均明显低于非FGR组(P＜0.05);但两组胎儿血流参数收缩期末流速(PSV)的差异无统计学意义(P＞0.05).S/D(UA)、RI(UA)、PI(UA)、RI(MCA)、PI(MCA)以及 PV 诊断 FGR 的 AUC 分别为 0.768、0.801、0.729、0.763、0.819、0.741,联合诊断的 AUC 为 0.924.结论:UA和MCA血流参数以及PV对于FGR均有较高的诊断效能,且三者联合诊断效能最高.
Objective:Exploring the diagnostic value of color Doppler ultrasound combined with placental volume(PV)detection for fetal growth restriction(FGR).Methods:A retrospective selection of 105 singleton pregnant women admitted to our hospital from March 2023 to February 2025 was conducted as the study subjects.Based on the occurrence of FGR,they were divided into the FGR group(n=46)and the non-FGR group(n=59).The clinical data of the two groups of pregnant women were compared,and the ultrasound parameters and PV data of the pregnant women were collected.Multivariate Logistic regression analysis was used to analyze the influencing factors of fetal growth restriction,and ROC curve analysis was performed to evaluate the diagnostic value of ultrasound parameters and PV for fetal FGR.Results:There were no statistically significant differences in maternal age,BMI,gestational age,gravidity,and parity between the two groups(P＞0.05),but the neonatal birth weight in the FGR group was significantly lower than that in the non-FGR group(P＜0.05).The fetal umbilical artery(UA)blood flow parameters,including the systolic-to-diastolic velocity ratio(S/D),resistance index(RI),and pulsatility index(PI),were significantly higher in the FGR group;moreover,the PV in the FGR group was significantly smaller than that in the non-FGR group(P＜0.05).The fetal middle cerebral artery(MCA)blood flow parameters RI and PI were significantly lower in the FGR group compared to the non-FGR group(P＜0.05);however,there was no statistically significant difference in the peak systolic velocity(PSV)of fetal blood flow parameters between the two groups(P＞0.05).The AUC values for S/D(UA),RI(UA),PI(UA),RI(MCA),PI(MCA),and PV in diagnosing fetal FGR were 0.768,0.801,0.729,0.763,0.819,and 0.741,respectively,with a combined diagnostic AUC of 0.924.Conclusion:The blood flow parameters of UA and MCA,as well as PV,all exhibit high diagnostic efficacy for the occurrence of FGR in fetuses,with the highest diagnostic efficacy observed when these three factors are combined.
