ANALYSIS OF DIAGNOSTIC ACCURACY OF ULTRASOUND (USG) IN PRENATAL DIAGNOSIS OF PLACENTA ACCRETA IN PAKISTAN

Introduction: Abnormally deep attachment of the placenta to the uterine wall is collectively called placenta accreta (PA).

Objectives of the study: The main objective of the study is to analyze the diagnostic accuracy of ultrasound (USG) in prenatal diagnosis of placenta accreta in Pakistan.

Material and methods: This cross-sectional study was conducted in Jinnah hospital, Lahore during November 2018 to April 2019. The data was collected from 100 patients. 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. All these patients were followed till delivery.

Results: The data was collected from 100 patients. The mean age of the patients was 39.56±5.56 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.

Conclusion: It is concluded that US is a good basic tool for investigation for suspected PA, and if the diagnosis remains unsettled, MRI is a useful back‐up measure.
