Abstract

Objective: To compare Doppler evaluation of the ductus venosus and contraction stress test (CST) in the prediction of adverse perinatal outcome in growth-restricted fetuses with evidence of hemodynamic redistribution and a non- reactive non-stress test (NST). Methods: A prospective study involving 252 patients were treated in the National Hospital of Gynecology and Obstetrics from January, 2011 to December 2014. Data were collected from all singleton pregnancies who underwent antenatal monitoring for fetal growth restriction, non-reactive NST, CST and ductus venosus waveform results. Peri-natal outcome was evaluated by means of four variables: an umbilical artery pH ≤ 7.15 and significant neonatal morbidity. Outcome was compared among fetuses delivered of their antenatal test. Logistic regression analysis was usedto analyze the relation between predictive and outcome variables. Results: 252 women met the inclusion criteria for the study. The sensitivity, spesifivity positive values, negative predictive values of abnormal ductus venosus waveform and CST results were 90.9%, 68.5%, 33.3%, 98%. Conclusion In growth-restricted fetuses with hemody-namic redistribution and a non-reassuring NST, Doppler assessment of the ductus venosus correlates with adverse perinatal outcome.
