Abstract:
Objective To discuss the diagnostic value of 3D-ultrasound for cord entanglement in monoam-niotic twins. Methods From November 2013 to March 2016,a total of 65 monoamniotic twinsunderwent routine obstetric ultrasonography to screen fetal abnormalities in our hospital. The cord was meticulously observedusing a systematic continuous sequence approach. Fetuses who showed cord entanglement by 2-D ultrasound or 3-D flow Doppler were all recruited. The gestational weeks,fetal malformation,ultrasonic image feature of cord entangle-ment,and clinicaloutcome were recorded and analyzed retrospectively. Results 4 monoamniotic twins showed cord entanglement. Three-dimensional color Doppler clearly delineated thefeatures of entanglement. At following-up of 8 fetuses,3 fetuses were found intrauterine fetal death and 3 fetuses with structural abnormalities except for 2 well infants.Conclusion Cord entanglement may threaten the safety of fetusesin monoamniotic pregnancies.In aid of 2-D ultrasound or 3-D flow Doppler in monoamniotic twins can help to find it in time ,monitor it carefully and provide evidence for obstetric treatment .
