Variation in Doppler indices along the length of the cord from the intraabdominal to the placental insertion.


AIM The aim of this study was to assess the feasibility of obtaining umbilical artery Doppler waveforms from the intraabdominal portion (perivesical) of the umbilical arteries and to compare the indices from this site to those from the free loop (FL) of cord placental insertion (PL) and abdominal insertion (AI). METHODS A cross-sectional study of 71… (More)
