ANALYSIS OF DIAGNOSTIC ACCURACY OF ULTRASOUND (USG) IN PRENATAL DIAGNOSIS OF PLACENTA ACCRETA TAKING OPERATIVE FINDINGS AS GOLD STANDARDS

Introduction: Morbidly adherent placenta (MAP) is defined as abnormal placental adherence, either in whole or in part of the placenta to the underlying uterine wall. Aims and objectives: The basic aim of the study is to analyze the diagnostic accuracy of ultrasound (USG) in prenatal diagnosis of placenta accreta taking operative findings as gold standards. Material and methods: This descriptive study was conducted in Allama Iqbal Memorial Teaching Hospital, Sialkot during May 2018 to September 2019. The data was collected from 50 patients of placenta accrete and we take operative findings as a gold standards. All those patients were at a high risk of abnormal placentation (placenta accrete, increta and percreta) regarding their clinical history of either one or all of the following: placenta previa, previous uterine interventional procedures (e.g. cesarean sections, dilation & curettage and myomectomy, maternal age of 35 years or more and grand multiparity. Results: The data was collected from 50 patients. The mean age of the patients was 34.56±4.56 years. In our study HB-difference (HB-dC) between pre- and post-operative values and estimated blood loss were the most significant risks factors for abnormal placentation added to risk factors known for placenta accrete. Postpartum SICU admission, prolonged hospital stay and CS hysterectomy were more common in the cases of placenta accreta associated with abnormal placentation. However, they were statistically insignificant. Conclusion: It is concluded that doppler ultrasound is useful in detecting placenta accreta is patients with placenta previa. Doppler ultrasound fairly good diagnostic accuracy for diagnosis placenta accreta
