Objective: to correlate the importance of late second trimester uterine artery doppler indices and waveform with the probabilities of adverse outcomes.
Study Design: Correlation study.
Place and Duration of Study: The study was conducted at the Department of Radiology, in collaboration with Department of Gynecology and Obstetrics at Pakistan Institute of Medical Sciences hospital, Islamabad, Pakistan, from Jan 2018 to Dec 2018.
Methodology: Fifty Patients labeled with pregnancy induced hypertension were included in the study. Doppler ultrasound assessments were performed at 20 -2 4weeks of gestation. Pulsitility Index, Resistive Index and Systolic Diastolic radio were calculated.
Results: Out of 50 patients, 36(72%) had normal and 16(28%) had abnormal Pulsitility index on right side, 34(68%) had normal and 16(32%) abnormal on left side, collectively 27(54%) normal, 13(26%) unilaterally abnormal and 10(20%) bilaterally abnormal. Among the patients with raised Pulsitility Index, 23(74%) had poor fetal outcome, whereas among those with normal Pulsitility Index 22(81.4%) patients had normal fetal outcome and only 5(18.5%) had poor fetal outcome. Results of current study show highly significant correlation between abnormal Pulsitility index and poor fetal outcome (r=0.56, p-value<0.001). Also significant association (OR-8.25 and p=0.001) was seen between abnormal pulsitility index and abnormal fetal outcome.
Conclusion: The uterine artery Doppler velocimetry should be used as a primary tool for fetomaternal surveillance in hypertensive pregnancies because the changes in uterine circulation strongly correlate with pregnancy outcome.
