SUMMARY
OBERVATION OF CHANGE I N DUCTUS VENOSUS DOPPLER INDICES I N INTRAUTERINE GROWTH RESTRICnON COMPARED TO NORMAL FETUSES
AT 32 TO 33 WEEKS' GRESTATION The ductus venosus Doppler ultrasound plays an important role in evaluation of fetal circulatioi^
Objectives: To obsen/e a change in the DV Dopplq indices In intrautenne growth restriction compared ra normal fetuses at 32 to 33 weeks' gestation!
T^P CHi Y HOC VIET NAM TAP 463 - THANG 2 - SO 1 - 2018 Subjects and method: Subjects: 125 pregnant
including 85 normal fetuses and 40 intrautenne growth restrictions at 32 to 33 weeks' gestation were treated with an ultrasound to measure ductus venosus Doppler indices. Method: A cross-sectional descriptive study used in the study. Results: In normal fetuses, a mean value of pulsatility Index: 0,73
± 0,13; Resistive Index: 0,68±0,16 and S/a was: 2,21
± 0,6. In intrautenne growth restriction, a mean value of pulsatility Index: 1,14±0,29; Resistive Index:
0,73±0,13 and S/a was: 3,75±1,15. Conclusions:
The pulsatility Index, Resistive Index and S/a in the intrauterine growth restriction were significantly higher than those in normal fetuses.
Keywords: Ductus venosus, Doppler ultrasound, Doppler indices, fetus, intrauterine gnawth restriction.
