Diagnostic accuracy of color doppler ultrasound in antenatal diagnosis of morbidly adherent placenta,taking operative findings of caesarean section as gold standard

Background: our ability to diagnose morbidly adherent placenta has changed over the last decade. ultrasound (usg),magnetic resonance imaging (mri) or a combination of these modalities are now-a-days utilized depending on the availability of expertise and equipment. ultrasound imaging is popular due to its low cost and accessibility and widely used for the screening of placental location and potential abnormal development. methods: a total of 69 booked gravid females in third trimester (diagnosed on early ultrasound) having diagnosed placenta previa on ultrasound in current pregnancy were selected. primigravida females and women having pregnancies complicated by hypertension,diabetes mellitus and cardiac disease were excluded. all the subjects were underwent colour doppler usg and the presence or absence of morbidly adherent placenta previa was noted. colour doppler ultrasonography findings were correlated with operative findings (taking as gold standard). results: mean age was 27.78±2.65 years. usg detected the morbidly adherent placenta in 8(11.59%) women. in usg positive patients,07 were true positive and 01 was false positive. among 61,usg negative patients,01 was false negative where as 60 were true negative (p=1.000). sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of color doppler ultrasound in antenatal diagnosis of map was calculated as 87.5%,98.36 %,87.5%,98.36% and 97.10% respectively. conclusion: this study concluded a higher diagnostic accuracy of color doppler ultrasound for antenatal diagnosis of morbidly adherent placenta in gravid females having placenta previa.
