Abstract
Objectives:
to evaluate the relationship between the ductus venosus (DV) and the variables of fetal growth in the first trimester in a Colombian pregnant population.
Methods:
a descriptive cross-sectional study was carried out with secondary data obtained from a multicenter study.526 patients were included between weeks 11 and 14 for gestational ultrasound follow-up attended in three health care institutions in Bogotá, Colombia, between May 2014 and October 2018. A bivariate descriptive analysis was carried out where the relationship between the characteristics of the DV in the first trimester and ultrasound findings.
Results:
the flow wave of the DV in the first trimester was normal in the entire sample, with a pulsatility index of the ductus venosus (DVPI) of 0.96±0.18. In addition, a negative correlation was found between the crown-rump length (CRL) and the DVPI (p<0.05).
Conclusion:
there is a relationship between the DVPI regarding the CRL, indicating an interest in this early marker in relation to fetal growth alterations; however, more studies are required to determine the usefulness of this variable with respect to fetal growth.
