Abstract EN
Objective.
To elaborate curves of longitudinal reference intervals of pulsatility index (PI) and systolic velocity (SV) for uterine (UtA), umbilical (UA), and middle cerebral arteries (MCA), in low risk pregnancies.
Methods.
Doppler velocimetric measurements of PI and SV from 63 low risk pregnant women between 16 and 41 weeks of gestational age.
Means (±SD) for intervals of gestational age and percentiles 5, 50, and 95 were calculated for each parameter.
The Intraclass Correlation Coefficients (ICC) were also estimated for assessing intra- and intervariability of measurements.
Results.
Mean PI of UtA showed decreasing values during pregnancy, but no regular pattern was identified for mean SV.
For UA, PI decreased and SV increased along gestation.
MCA presented PI increasing values until 32–35 weeks.
SV showed higher levels with increasing gestation.
High ICC values indicated good reproducibility.
Conclusions.
Reference intervals for the assessment of SV and PI of UtA, UA, and MCA were established.
These reference intervals showed how a normal pregnancy is expected to progress regarding these Doppler velocimetric parameters and are useful to follow high risk pregnancies.
The comparison between results using different curves may provide insights about the best patterns to be used.
