摘要
目的应用彩色多普勒超声观测中孕期子宫动脉及髂内动脉血流频谱的变化,分析其预测不良妊娠结局的价值。方法收集我院中孕期子宫动脉血流频谱出现舒张早期切迹的孕妇46例(切迹组)和子宫动脉舒张早期无切迹的正常孕妇51例(对照组),应用彩色多普勒超声获得子宫动脉及髂内动脉的收缩期与舒张期峰值血流速度比值(S/D)、搏动指数(PI)、阻力指数(RI),以及髂内动脉峰值血流加速时间(IIA-AT)、内径及血流量,比较两组上述参数的差异,分析子宫动脉及髂内动脉血流参数对不良妊娠结局的检出率。结果与对照组比较,切迹组子宫动脉S/D、PI、RI和髂内动脉S/D均升高,IIA-AT延长,差异均有统计学意义(均P<0.05)。切迹组发生不良妊娠结局9例;对照组发生不良妊娠结局1例。子宫动脉舒张早期切迹联合IIA-AT、髂内动脉S/D对不良妊娠结局的检出率(50.0%)高于子宫动脉舒张早期切迹单独应用(19.6%),尤其对子痫前期的检出价值更高(40.0%vs.10.9%),差异均有统计学意义(均P<0.05)。结论中孕期子宫动脉舒张早期切迹联合髂内动脉血流频谱参数可以预测不良妊娠结局的发生,为临床及早诊疗提供客观依据。
Objective To observe the changes of the blood flow spectrum of the uterine artery and internal iliac artery in the mid-trimester of normal pregnancy by color Doppler ultrasound,and to analyse the value of it in predicting adverse pregnancy outcomes.Methods A tatal of 46 pregnant women with a diastolic cut in the flow spectrum of the uterine artery during mid-pregnancy(cut group)and 51 pregnant women without a diastolic cut at mid-pregnancy(control group)were collected.The systolic to diastolic peak flow velocity ratio(S/D),the pulsatility index(PI),the resistance index(RI),the peak internal iliac artery(IIA-AT),the internal diameter and flow rate of the internal iliac artery were obtained by color Doppler ultrasound.The differences of above flow parameters between the two groups were compared,and the detection rate of adverse pregnancy outcomes by uterine artery and internal iliac artery flow parameters were analyzed.Results Compared with the control group,uterine artery S/D,PI,RI and internal iliac artery S/D were significantly increased,and IIA-AT was significantly prolonged in the cut group,there were statistically significant differences(all P<0.05).9 cases of abverse pregnancy outcomes in cut group,and 1 case of abverse pregnancy outcomes in control group.The detection rate of adverse pregnancy outcomes was higher in early diastolic uterine artery notching combined with IIA-AT and internal iliac artery S/D(50.0%)than that of early diastolic uterine artery notching alone(19.6%),especially for the detection value of preeclampsia(40.0%vs.10.9%),with statistically significant differences(all P<0.05).Conclusion The combination of early diastolic uterine artery notching with internal iliac artery flow spectral parameters in mid-trimester can predict the occurrence of adverse pregnancy outcomes and provide objective basis for early clinical management.
