To assess the correlation between first-trimester uterine artery Doppler measurements and maternal serum levels of free beta-hCG and pregnancy-associated plasma protein A (PAPP-A).
Observational study.
Teaching hospital.
PATIENT(S): Four hundred thirty-three women at 10-14 weeks of gestation.
INTERVENTION(S): Doppler ultrasound of the uterine arteries. Fluorimetric immunoassays for free beta-hCG and PAPP-A.
MAIN OUTCOME MEASURE(S): Uterine artery mean resistance index (RI), pulsatility index (PI), and number of early diastolic notches. Maternal serum levels of free beta-hCG and PAPP-A.
RESULT(S): There were 401 uncomplicated pregnancies. In this group, free beta-hCG and PAPP-A did not significantly correlate with uterine artery RI or PI (r values between -0.089 and 0.029, all nonsignificant). Free beta-hCG and PAPP-A levels did not significantly change with the number of notches. Uterine artery resistance and PAPP-A levels were independently correlated with birth weight.
CONCLUSION(S): Preliminary evidence suggests that first-trimester uterine artery Doppler measurements do not correlate with maternal serum levels of free beta-hCG and PAPP-A. This may allow their combined use in multivariate screening for pregnancy complications.
评估孕早期子宫动脉多普勒测量值与母体血清游离β-人绒毛膜促性腺激素(β-hCG)及妊娠相关血浆蛋白A(PAPP-A)水平之间的相关性。
观察性研究。
教学医院。
433名妊娠10 - 14周的女性。
子宫动脉多普勒超声检查。游离β-hCG和PAPP-A的荧光免疫测定。
子宫动脉平均阻力指数(RI)、搏动指数(PI)及舒张早期切迹数量。母体血清游离β-hCG和PAPP-A水平。
有401例无并发症妊娠。在该组中,游离β-hCG和PAPP-A与子宫动脉RI或PI无显著相关性(r值在-0.089至0.029之间,均无统计学意义)。游离β-hCG和PAPP-A水平不会随切迹数量显著变化。子宫动脉阻力和PAPP-A水平与出生体重独立相关。
初步证据表明,孕早期子宫动脉多普勒测量值与母体血清游离β-hCG和PAPP-A水平无关。这可能使其可联合用于妊娠并发症的多变量筛查。
