OBJECTIVES: The objective of this study is to examine the performance of Ductus venosus (DV) Doppler done at the routine first trimester screening (11-13 + 6 weeks) in predicting the adverse fetal outcomes in Indian population.
METHODS: This observational study was conducted between 2013 and 2019, on 4340 singleton pregnancies. Ductus Doppler were considered abnormal if DV pulsatility index values were >95th centile for that gestation or with a reversed "a" wave. Anatomical survey was done to rule out other abnormalities. Women were followed up till delivery and outcomes were divided into 4 groups: 1) aneuploidies; 2) cardiac defects; 3) non-cardiac structural abnormalities; and 4) miscarriages before 24 weeks or fetal deaths after 24 weeks.
RESULTS: Prevalence of abnormal DV Doppler is 5.12% (205/4004). There were significantly higher number of fetal losses (4.4 versus 0.3%), aneuploidies (10.2 versus 1.7%), fetal cardiac defects (5.9 versus 1.4%), and non-cardiac structural defects (5.4 versus 1.4%) among the pregnancies with abnormal DV Doppler in comparison to those with normal flow (P < .001). Logistic regression analysis has shown that significant contribution to fetal chromosomal abnormalities and cardiac defects was associated with abnormal DV. Other factors which were found to have a significant association with adverse fetal outcome were increased nuchal translucency and increased body mass index (BMI).
CONCLUSION: DV Doppler in first trimester can be used as a screening tool for cardiac defects and fetal deaths. Women with abnormal DV Dopplers should be offered fetal echocardiography at 18-22 weeks and third trimester growth scans with Dopplers.
