Doppler ultrasound for antenatal detection of morbidly adherent placenta in patients presented with placenta previa major degree

Abstract

OBJECTIVE: To determine the diagnostic accuracy of Doppler ultrasound for antenatal detection of morbidly adherent placenta in patients presented with placenta previa major STUDY DESIGN: Cross sectional validation survey. SETTING: radiology and Gynecology department of Allied Hospital, Faisalabad. DURATION OF STUDY: Six month (31-05-2014 to 30-11-2014) after approval of synopsis. SUBJECTS AND METHODS:A total of 145 cases were included in this study. Doppler ultrasound was done to detect presence / absence of placenta accreta and patients were followed till delivery and per-operative findings were compared with   Doppler USG findings. RESULTS: Sensitivity was found to be 86.5%, specificity 90.4%, diagnostic accuracy 95%, positive predictive value 95.7% and negative predictive value 72.5%.CONCLUSION.Doppler ultrasound is useful in detecting placenta accreta is patients with placenta previa.
