| 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 .GEQ.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. (author abst.) |
