Relationship between Body Mass Index and Ductus Venosus Doppler Measurements at 11-14 Gestational Weeks

Özet

Introduction: In this study, we aimed to investigate the possible causative relationship between maternal obesity and flow patterns of ductus venosus. Methods: One hundred twenty three pregnant women with a body mass index of 25 or higher and 83 pregnant women with body mass index lower than 25 in gestational weeks between 11-14, were included in the present study. Results: The findings showed that there was no statistically significant difference between the two groups for a combined test, three-component antenatal tests, second-level ultrasonography. In 12% of the women, loss of a wave and/or inverse a wave was noted. In the rest of the women, there were no pathological waves. In 4.8% of women with a BMI less than 25, there was an abnormality in ductus venosus flow pattern, whereas this ratio was 17% in the other group consisted of women with BMI higher than 25; and the difference was statistically significant (p=0.008). Discussion and Conclusion: We concluded that maternal hyperglycemia and high body mass index might cause abnormal flow patterns in ductus venosus in pregnancies with normal first-trimester scanning and abnormal flow patterns of ductus venosus.
