Objective:
Doppler studies of the fetal circulation have demonstrated the importance of ductus venosus velocimetry in the monitoring abnormal course of pregnancy.
Design:
Estimation of the ductus venosus Doppler reference ranges between 10-19th week of pregnancy.
Material And Methods:
The ductus venosus blood flow has been studied in 140 consecutive fetuses between 10 and 19 week of pregnancy. When a midsagittal view of the fetus was obtained, color Doppler was used to visualize the ductus venosus. The pulsed Doppler sample volume was then placed on it, in the isthmic portion.
Results:
The mean PIV ranged from 1.09 in the first trimester of pregnancy to 0.96 in the second trimester.
Conclusion:
A decrease in mean PIV values was observed in the course of pregnancy. In the normal course of pregnancy A-wave was observed.
