Abstract
Aim of the work
This study was aiming to compare changes in Doppler FVWs of fetal umbilical artery (UA), fetal middle cerebral artery (MCA) and utero-placental circulation in normal pregnancy and in pregnancy associated with reduced AFI.
Also this study was aimed to evaluate the role of Doppler FVWs in prediction of adverse perinatal outcome in pregnancies associated with reduced AFI.
CONCLUSIONS
The present study concluded that:
• In normal pregnancy, FVWs from the uterine artery, UA and MCA showed gradual increase in the EDF with subsequent decline in Doppler indices.
• Doppler indices of the uterine artery and UA are significantly higher in reduced AFI. However the fetal MCA give little information beyond that obtained from UA FVWs.
• Umbilical artery FVWs are useful diagnostic tool to assess fetal well being in reduced AFI. It should be a useful adjunct to the current methods of fetal surveillance.
• When reduced AFI is associated with abnormal Doppler waveform during third trimester, it carries an increased risk of adverse perinatal outcomes. Larger studies should be considered to find whether interventions according to abnormal Doppler indices may prevent some of the poor perinatal outcomes.
• No significant differences in adverse pregnancy outcome in pregnancy associated with borderline AFI and oligohydramnios.
