【摘要】：目的探讨正常孕妇孕早期至孕中期子宫动脉血流参数的变化规律,为相关疾病的预测提供依据。方法孕11~14周及孕18~20周超声分别检测双侧子宫动脉搏动指数(PI)、阻力指数(RI),观察上述指标在早孕-中孕的变化情况。结果正常孕妇左侧子宫动脉PI、RI早孕期分别为(1.56±0.518)及(0.71±0.112),中孕期降至(1.13±0.424)及(0.61±0.109),右侧子宫动脉PI、RI早孕期(1.50±0.518)、(0.70±0.106),中孕期降至(1.01±0.391)、(0.57±0.117)。子宫动脉阻力参数PI、RI早孕期与中孕期比较差异有统计学意义(P0.05),孕11~14周子宫动脉阻力参数左右两侧比较差异无统计学意义(P0.05),孕18~20周子宫动脉阻力参数两侧比较差异有统计学意义(P0.05)。结论从早孕期至中孕期,正常孕妇子宫动脉阻力参数下降。
[Abstract]:Objective to investigate the changes of normal pregnant women in early pregnancy and uterine artery blood flow parameters, provide the basis for the prediction of related diseases. Bilateral uterine artery pulsatility index were measured at 11~14 weeks and methods 18~20 gestational weeks ultrasound (PI), resistance index (RI), observed the changes in the index pregnancy - pregnancy. Results the left uterine artery of normal pregnant women in early pregnancy were PI, RI (1.56 + 0.518) and (0.71 + 0.112), in the second trimester of pregnancy to (1.13 + 0.424) and (0.61 + 0.109), the right uterine artery PI, RI in early pregnancy (1.50 + 0.518), (0.70 + 0.106), to 1.01 (in the second trimester of pregnancy + 0.391), (0.57 + 0.117). Uterine artery resistance parameters of PI, RI had significant difference in early pregnancy and pregnancy (P0.05), no statistically significant 11~14 weeks pregnant uterine artery resistance parameters of left and right sides of the difference (P0.05), there were two 18~20 weeks pregnant uterine artery resistance parameter difference Significance (P0.05). Conclusion from the early pregnancy to the middle pregnancy, the uterine artery resistance parameters of normal pregnant women decreased.
