Description
Abstract
Aim: The aim of the present study was to investigate the diagnostic value of MCA/UA pulsatility index ratio for
the prediction of adverse perinatal outcome in patients with high-risk pregnancy.
Methods: The study group consisted of 200 women admitted to Department of Obstetrics & Gynaecology. All
patients had undergone serial color Doppler ultrasound. The Umbilical Artery color Doppler waveforms were
obtained from a free-floating portion of the umbilical cord during minimal fetal activity and the absence of fetal
breathing. All measurements were performed in the semi-recumbent positions with the head and chest slightly
elevated.
Results: 55% had vaginal delivery and remaining 45% had Caesarean delivery in the present study. 32% had
pregnancy induced hypertension followed by PIH+IUGR (25%). Our results suggested that the MCA/UA PI
Doppler ratio of less than 1 was a good predictive tool for neonatal outcome in preeclamptic and hypertensive
pregnant women and could be used to identify fetuses at risk of morbidity and mortality. Fetuses with abnormal
Doppler MCA/UA PI ratio in our study had a significantly lower birth weight, lower gestational age at delivery,
l significantly higher incidence of perinatal deaths, higher incidence of admission to NICU and longer duration
of treatment there, lower Apgar score at 5-minute.
Conclusion: Doppler study is a noninvasive method for assessing the hemodynamic function of the fetus and
mother. There is a direct correlation between high-risk pregnancy with abnormal Doppler findings in the
umbilical, middle cerebral artery, and CPR compared to non-high-risk pregnancies.
