目的:探讨多普勒超声子宫动脉血流参数联合凝血相关指标对易栓症所致复发性流产妊娠结局的预测价值.方法:选取2020年1月至2023年1月北京市海淀医院妇科门诊就诊的82例复发性流产患者,所有患者均进行相关治疗,并统计随访结果.所有患者于入院次日治疗前均进行子宫动脉搏动指数(PI)、阻力指数(RI)、收缩压最大血流速度(S)与舒张末期最大血流速度(D)比值(S/D),以及活化部分凝血活酶时间(APTT)、凝血酶原时间(PT)、纤维蛋白原(FIB)、凝血酶时间(TT)及D二聚体(D-D)检测.采用Pearson相关性分析PI、RI与S/D与APTT、PT、FIB、TT、D-D的相关性;采用受试者工作特征(ROC)曲线下面积(AUC)分析PI、RI、S/D、APTT、PT、FIB、TT及D-D单独检测及联合检测预测易栓症所致复发性流产妊娠结局的价值.结果:随访结果显示,82例复发性流产患者妊娠成功49例,妊娠丢失33例,妊娠成功孕妇的PI、RI与S/D均明显低于妊娠丢失孕妇,差异有统计学意义(t=10.598、6.693、3.059,P＜0.05);APTT、PT、FIB、TT、D-D水平均明显低于妊娠丢失孕妇,差异有统计学意义(t=9.552、96.462、22.767、5.100、95.805,P＜0.05);PI与APTT、PT、FIB、TT及D-D均存在正相关性(r=3.178,P＜0.05),RI与APTT、PT、FIB、D-D均存在正相关性(r=3.246,P＜0.05),S/D与PT、FIB、TT、D-D均存在正相关性(r=3.246,P＜0.05);PI、RI、S/D、APTT、PT、FIB、TT及D-D单独检测及联合检测预测易栓症所致复发性流产妊娠结局灵敏度分别为42.40%、48.50%、39.40%、48.50%、63.60%、72.70%、42.40%、39.40%、84.80%,特异性分别为98.00%、71.40%、55.10%、75.50%、59.20%、71.40%、77.60%、85.70%、98.80%,AUC分别为0.674、0.685、0.409、0.646、0.784、0.788、0.566、0.563和0.941.结论:PI、RI及S/D子宫动脉血流参数与APTT、PT、FIB、TT和D-D凝血相关指标单独及联合检测预测易栓症所致复发性流产妊娠结局均具有一定的价值,且联合检测的预测价值更高.
Abstract
Objective:To explore the predictive value of uterine artery blood flow parameters of Doppler ultrasound combined with coagulation related indicators on the pregnancy outcome of recurrent abortion caused by thrombophilia.Methods:A total of 82 patients with recurrent abortion who admitted to the department of gynecology outpatient of Beijing Haidian Hospital from January 2020 to January 2023 were selected.All patients received relevant treatment,and the follow-up results were calculated as statistic method.Before treatment on the day after admission,uterine artery pulse index(PI),resistance index(RI),the ratio of the maximum blood flow velocity of systolic pressure(S)to the maximum blood flow velocity of end-diastolic(D)(S/D),and activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(FIB),thrombin time(TT)and D-dimer(D-D)of all patients were detected.Pearson correlation analysis was adopted to analyze the correlations between PI,RI,S/D and each of APTT,PT,FIB,TT and D-D.Receiver operating characteristic(ROC)curve was used to analyze the values of single PI,RI,S/D,APTT,PT,FIB,TT and D-D,and the value of the combined detection of them in predicting the pregnancy outcome of recurrent abortion caused by thrombophilia.Results:Follow up results showed that 49 cases of 82 patients with recurrent abortion were successful pregnancy and 33 cases of them occurred pregnancy loss,and the PI,RI and S/D of pregnant women with successful pregnancy were significantly lower than those of pregnant women who occurred pregnancy loss,with statistical significance(t=10.598,6.693,3.059,P<0.05).The levels of APTT,PT,FIB,TT and D-D of pregnant women with successful pregnancy were significantly lower than those of pregnant women who occurred pregnancy loss,and the differences were statistically significant(t=9.552,96.462,22.767,5.100,95.805,P<0.05),respectively.PI appeared respectively positive correlation with APTT,PT,FIB,TT and D-D(r=3.178,P<0.05),and RI appeared respectively positive correlation with APTT,PT,FIB and D-D(r=3.246,P<0.05),and S/D also appeared respectively positive correlation with PT,FIB,TT and D-D(r=3.246,P<0.05).The sensitivities of single PI,RI,S/D,APTT,PT,FIB,TT and D-D detection,and the combined detection of them were respectively 42.40%,48.50%,39.40%,48.50%,63.60%,72.70%,42.40%,39.40%and 84.80%in predicting the pregnancy outcome of recurrent abortion caused by thrombophilia.The specificities of them were respectively 98.00%,71.40%,55.10%,75.50%,59.20%,71.40%,77.60%,85.70%and 98.80%,and the AUC values of them were respectively 0.674,0.685,0.409,0.646,0.784,0.788,0.566,0.563 and 0.941.Conclusion:Both single and combination of PI,RI and S/D of uterine artery blood flow parameters,as well as APTT,PT,FIB,TT and D-D of coagulation related indicators,have a certain value in predicting pregnancy outcome of recurrent abortion caused by thrombophilia,and the combined detection has higher predictive value.
