ABSTRACT
Background: Pregnancy during adolescence has been rising in the past
years, and it is well known that preeclampsia affects teenagers,
because maternal age and primigravida are risk factors. There
are different ways and methods to predict preeclampsia, for example
doppler velocimetry.
Objective: Determine S/D ratio of uterine artery in pregnant teenagers
between 24-28 weeks and correlation with preeclampsia.
Material and Method: Observational study in 50 pregnant teenagers
(14-19 years) obtaining uterine artery waveform at 24-28 weeks gestation
recording S/D ratio.
Results: Sensitivity and specificity of 90% with a positive predictive
value of 69.23% and negative predictive value of 97.3%. 13 patients
had S/D ratio greater than 2.6, of which 5 had gestational hypertension,
3 with preeclampsia, 1 with Fetal Growth Restriction, 4 with normal
pregnancy. Relative Risk was 25.62 (3.58-183.13) with odds ratio of
81.00 (6.83-2260.88) and
p value 0.00002.
Conclusion: analysis of uterine artery flow velocity waveforms is a
method to predict preeclampsia.
