彩色多普勒超声检测孕早期先兆流产患者子宫动脉血流参数对预后的预测价值

Prognostic Vabue of Uterine Artery Blood Flow Parameters Detected by Color Doppler Ultrasound in Patients with Threat.ened Abortion in the Early Stage of Pregnancy

目的分析孕早期先兆流产(TA)患者子宫动脉血流参数对预后的预测价值。方法纳入82例孕早期TA患者为研究组,同期健康妊娠人群102例为对照组,两组均采用彩色多普勒超声检测子宫动脉血流参数,比较不同分组孕妇的血流参数,分析S/D、RI、PI单独与联合检测预测孕早期TA患者预后的效能。结果对照组、保胎成功组、保胎失败组的S/D、RI、PI水平呈升高趋势(P<0.05)。ROC曲线显示,S/D、RI、PI联合检测对孕早期TA预后的预测价值最高(AUC为0.923,P<0.01)。结论孕早期TA患者的子宫动脉血流参数S/D、RI、PI均较高,联合检测子宫动脉血流参数对预后具有较高的预测价值。

Objective To analyze the prognostic value of uterine artery blood flow parameters in patients with threatened abortion(TA)in the early stage of pregnancy.Methods 82 patients with TA in the early stage of pregnancy were selected as the study group,and 102 healthy pregnant women in the same period were selected as the control group.Color Doppler ultrasound was used to detect uterine artery blood flow parameters in both groups.The blood flow parameters of pregnant women in different groups were compared,and the efficacies of single and combined detection of S/D,RI and PI in predicting the prognosis of TA patients in the early stage of pregnancy were analyzed.Results The levels of S/D,RI and PI in the control group,the success fetal preservation group and the failure fetal preservation group showed increasing trends(P<0.05).The ROC curve showed that the combined detection of S/D,RI and PI had the highest predictive value for the prognosis of TA in the early stage of pregnancy(A UC=0.923,P<0.01).Conclusions The uterine artery blood flow parameters including S/D,RI and PI of TA patients in the early stage of pregnancy are high,and the combined detection of uterine artery blood flow parameters have high predictive value for prognosis.
