Early pregnancy screening using uterine artery pulsatility index (Pi) can identify women at high risk for preeclampsia (PE). This method aids in targeted antenatal care for better maternal and neonatal outcomes.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Diagnostic Imaging in Pregnancy
Background:
- Preeclampsia (PE) is a severe pregnancy complication associated with significant maternal and neonatal mortality.
- Accurate risk assessment in early pregnancy is crucial for timely intervention and improved antenatal care.
- Identifying predictive markers for PE can optimize management strategies and reduce adverse outcomes.
Purpose of the Study:
- To determine if early pregnancy ultrasound markers can predict the risk of developing preeclampsia.
- To identify pregnant women at higher risk for preeclampsia for targeted antenatal care.
- To evaluate the prognostic importance of Doppler ultrasound indices in early gestation.
Main Methods:
- Prospective study involving 205 pregnant women undergoing screening at 11-13 weeks of gestation.
- Data collection included questionnaires and transabdominal Doppler ultrasound of the uterine artery.
- Pulsatility index (Pi) and resistance index (Ri) were measured and converted to multiples of the median (MoM).
Main Results:
- Nine out of 205 women with high Pi values at 12-13 weeks gestation subsequently developed preeclampsia or pregnancy-induced hypertension.
- Elevated Pi values demonstrated a correlation with the development of PE/PIH.
- Resistance index (Ri) values showed no significant importance in forecasting preeclampsia development.
Conclusions:
- Measurement of the uterine artery pulsatility index (Pi) at 12-13 weeks gestation is a valuable prognostic marker for preeclampsia.
- The presence of diastolic incisures in Doppler waveforms also holds prognostic importance for PE.
- Doppler ultrasound indices, particularly Pi, can aid in early risk stratification for preeclampsia.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
