Abstract
This cross sectional study was carried out on 60 pregnant Bangladeshi women in the department of Radiology and Imaging, BIRDEM for measurement of Pulsatility Index (PI) of umbilical artery of their fetuses by duplex colour Doppler sonography during 2nd and 3rd trimester of pregnancies. Considering total 2nd and 3rd trimesters the mean PI value of umbilical artery was 1.24 (SD +/- 0.27). While considering the gestational in separate trimesters, study showed that the value of PI in 2nd trimester was 1.33 (SD +/- 0.29) and in 3rd trimester PI was 1.18 (SD +/- 0.25). Paired t test shows there was a highly significant (t = 35.79, df = 59, Level of significance = 0.001) difference between mean values of PI in different gestational ages. It was observed that there was gradual decrease of PI value with increase of gestational age (r = -0.207) but this decrease of PI was not statistically significant (p = 0.113). Regression analysis between dependent PI value and independent gestational age showed linear negative relationship but this was not statistically significant (p = 0.11). This study revealed that the Pulsatility index of umbilical artery was decreased with increase of gestational age from 2nd to 3rd trimester.
Highlights
Duplex color Doppler sonography is one of the popular imaging modalities in the department of radiology and imaging as well as to the physian to assay the condition of blood vessel and flow pattern in various diseases
Like Pulsatility Index (PI) value, Resistance Index (RI) value was reduced from 0.75(±0.06) to 0.69(±0.7) while pregnancy was running from 2nd to 3rd trimester
Regression analysis between dependent PI value and independent gestational age showed linear negative relationship existed between value of PI and gestational age but this was not statistically significant (p=0.11)
Summary
Doppler ultrasound in 2nd and 3rd trimester play vital role in determining foetal outcome as Doppler wave form shows increased resistant to flow in 2nd and 3rd trimesters which are associated with poor pregnancy outcome[3]. For this continuous wave Doppler, pulse Doppler, color flow, power Doppler are utilized to measure PSV, EDV, PI, RI, and S/D ratio. Among all those parameters PI is the most important predictor of normal pregnancy outcome[4,5]
