Abstract

Objectives: To assess the diagnostic accuracy of color Doppler ultrasound in antenatal diagnosis of placenta accreta taking histopathology as gold standard. Study Design: Prospective study. Setting: Department of Obstetrics and Gynaecology, Gambat Institute of Medical Sciences Gambat, Khairpur Sindh. Period: 1st December 2018 to 30th June 2019. Material & Methods: Women aged 20-45 years with previous history of placenta accrete and uterine scar were selected for the study. Informed consent was taken from women with placenta Previa and previous scar to undergo Doppler ultrasound. Results: A total of 115 patients participated in this study during one year time period. The mean age of e participants was found to be 33.71±5.61 years. The mean gestational age was 35.24±2.7weeks. Out of total 115 cases, previous cesarean section was found in 48 (41.7%) cases and previous history of placenta accreta was found in 9 (7.8%) cases. Sensitivity of Color Doppler ultrasound in diagnosis of placenta accreta was 85.7% and specificity 96.6%. Conclusion: There has always been a debate about the use of different modalities in detection of placenta accreta and its surgical management. Our study shows high sensitivity and specificity of color Doppler ultrasound in detection of placenta accreta. Large scale studies must be carried out on government level comparing the results of color Doppler and MRI and their outcomes.
