| 目的 应用彩色多普勒超声观察正常孕妇中孕期子宫动脉及髂内动脉血流频谱的变化，分析其在不良妊娠结局预测中的价值。方法 收集我院中孕期子宫动脉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孕妇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），以及髂内动脉收缩期峰值血流加速时间（IIA-AT）、内径及血流量（IIA-Q），比较两组上述血流参数的差异，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均明显升高，IIA-AT明显延长，差异均有统计学意义（均P＜0.05）。子宫动脉舒张早期切迹联合IIA-AT、IIA-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%），尤其对子痫前期检出价值更大，差异均有统计学意义（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更好地检出不良妊娠结局的发生，可为临床及早诊疗提供客观依据。 |

| Abstract: |
| Objective To investigate the value of the Doppler flow spectrum of uterine artery and internal iliac artery in the second trimester of normal pregnancy in predicting adverse pregnant outcome. Methods Forty-six pregnant women with bilateral notch uterine arterial blood flow otherwise normal who were performed fetal echocardiography in Tangdu Hospital from May 2020 to December 2021 in the second trimester were collected as the case group and 51 normal pregnant women as the control group. The ratio of systolic to diastolic peak blood flow velocity (S/D), pulsatility index (PI), resistance index (RI), and peak systolic blood flow acceleration time (IIA-AT), internal diameter, and blood flow volume (IIA-Q) of the uterine artery and internal iliac artery in pregnant women were obtained by color Doppler ultrasound.To compare the difference of the above blood flow parameters between the two groups and analyze the detection rate of uterine artery and internal iliac artery blood flow parameters for adverse pregnancy outcomes.Results Compared with the control group, uterine artery S/D, PI, RI in the notch group were significantly increased, IIA-AT was significantly prolonged, and the difference was statistically significant (all P<0.05). The detection rate of the early diastolic notch of uterine artery combined with IIA-AT and IIA-S/D for adverse pregnancy outcomes (50.0%) was higher than that of the early diastolic notch of uterine artery alone (19.6%), especially for preeclampsia, the difference was statistically significant (P<0.05).Conclusion The early diastolic notch of uterine artery combined with the blood flow spectrum parameters of internal iliac artery in the middle pregnancy period can better detect the occurrence of adverse pregnancy outcomes, which can provide an objective basis for early clinical diagnosis and treatment. |
