背景：我们在低风险人群中评估了基于胎盘血管超声活检（PVS）的18-22周妊娠胎盘灌注，以预测胎儿生长受限（FGR）或妊娠高血压综合征[PIH;方法对226例妊娠[FGR，二十五岁;在妊娠18-22周时，适合胎龄（阿加）191例;大于胎龄（LGA）10例] [PIH 13例（GH 7例，PE 6例）和非PIH 213例]。结果FGR、阿加、LGA孕妇的血管指数（VI）、血流指数（FI）、血管血流指数（VFI）无显著性差异。妊高征和非妊高征孕妇的VI、FI或VFI值无显著差异。GH和PE妊娠之间的VI、FI或VFI值也没有显着差异。结论18-22周的3D能量多普勒胎盘血管指数不能用于预测低风险人群中发生FGR或PIH的高危妊娠。
Background We assessed placental perfusion based on placental vascular sonobiopsy (PVS) at 18-22 weeks of gestation in a low-risk population to predict fetal growth restriction (FGR) or pregnancy-induced hypertension [PIH; gestational hypertension (GH) and preeclampsia (PE)].Methods PVS using three-dimensional (3D) power Doppler ultrasound with the VOCAL imaging analysis program was performed in 226 pregnancies [FGR, 25; appropriate-for-gestational age (AGA) 191; and large-for-gestational age (LGA), 10] [PIH, 13 (GH, 7 and PE, 6) and non-PIH, 213] at 18-22 weeks of gestation. 3D power Doppler indices such as the vascularization index (VI), flow index (FI), and vascularization flow index (VFI) using PVS were calculated in each placenta.Results There were no significant differences in VI, FI, or VFI values among FGR, AGA, and LGA pregnancies. No significant differences in VI, FI, or VFI values between PHI and non-PIH pregnancies were noted. There were also no significant differences in VI, FI, or VFI values between GH and PE pregnancies.Conclusions 3D power Doppler placental vascular indices at 18-22 weeks could not be used to predict high-risk pregnancies that develop FGR or PIH in a low-risk population.
