Abstract

Objective: To assess the diagnostic accurateness of grey ultrasound in the antenatal diagnosis of morbidly adherent placenta, taking per- operative findings of caesarean section as gold standard.

Study Design: Cross sectional study.

Place and Duration of Study: Radiology Department in collaboration with Obstetrics and Gynecology Department, Pak Emirates Military Hospital, Rawalpindi Pakistan, from Aug 2019 to Aug 2020.

Methodology: 89 pregnant women registered with diagnosis of placenta Previa in present pregnancy were included. Primi-gravida and females with pregnancies complicated by diabetes, heart disease and hypertension were omitted from study. All patients endured grey ultrasound examination and revealed absence or presence of morbidly adherent placenta Previa. Grey ultrasound results were associated with surgical per-operative findings.

Results: The mean age of the patients was 27.78±2.65 years. In patients with positive ultrasound results, 01 was false positive and 10 were true positive. Of the 78 ultrasound negative results, true negative were 70 patients and 02 were false negative (p=1000). Of the 78 ultrasound negative results, true negative were 70 patients and 02 were false negative (p=1000). Specificity, sensitivity, negative predictive value, positive predictive value and diagnostic accurateness of grey ultrasound in the antenatal analysis of morbidly adherent placenta are 98.36%, 87.5%, 98.36%, 87.5% and 97.10%, respectively.

Conclusion: In this study, the grey ultrasonography showed greater diagnostic accuracy in the prenatal detection of the morbidly adherent placenta in pregnant women with placenta previa.
