Circulating Angiogenic Factors and Abnormal Uterine Artery Doppler Velocimetry in the Second Trimester

Abstract

Concentrations of maternal soluble Flt-1 and free PlGF in the second trimester do not appear to be altered in women with abnormal UAD. This suggests that these biochemical markers are independent of the increased placental resistance seen with abnormal uterine artery Doppler.
