Abstract
Objective: To evaluate the role of umbilical Doppler velocimetry as a comprehensive test for the prediction of discordant twins. Methods: The sets of twins were studied with duplex Doppler velocimetry for umbilical artery in third trimester. A systolic/diastolic ratio was measured for each twin. The average difference in the ratios between each twin ≥ 0.4 was used to indicate abnormal test. Discordancy was identified when the birth weight difference of > 25%. Results: Among the 52 sets of twin pregnancies studied, 40 sets of twins fulfilled the study criteria. Eight sets of twins were discordant (20%). The mean gestational age at delivery was 37.15 ± 2.24 weeks (range 28 to 41 weeks). The test correctly identified 6 of the 8 growth discordant twins which had a sensitivity of 75%, specificity of 68.75%, and accuracy of 70%. Conclusion: Umbilical Doppler velocimetry is useful in prediction of discordant twins.
