DATASET DV study.sav

Prospective observational study in singleton uncomplicated pregnancies between 24 and 34 weeks gestation . AIm: To compare the ductus venosus (DV) pulsatility index for veins (PIV) obtained in a mid-sagittal plane with that obtained in an oblique transverse plane of the fetal abdomen
Methods: Two consecutive recordings of DV Doppler waveform were obtained in each woman: one in a mid-sagittal plane, and the other in an oblique transverse plane of the fetal abdomen. The paired t-test was used to compare results obtained with the two approaches. A change of the DV-PIV of 0.10 or more was considered clinically relevant.
RESULTS: The mean DV-PIV was 0.57 (± 0.16 SD) in the sagittal plane and 0.53 (± 0.16 SD) in the transverse plane. The mean difference (0.03) was statistically significant (p=0.04), but not clinically relevant
conclusions: The difference in the DV-PIV obtained in a mid-sagittal plane compared to a transverse plane of the fetal abdomen is small and not clinically significant
