Abstract

Background: Maternal mortality from placenta accrete is estimated to be 6-7 % regardless of the type of the operation. Aim Of The Study :To evaluate the influence of transabdominal versus transvaginal ultrasound in assessing placental invasion in situations of placenta previa anterior wall with a prior uterine scar using the unified ultrasonographic characteristics proposed by "EW-AIP," as well as to assess the sensitivity and accuracy of each characteristic by evaluatingthem to the pregnancy''s end results. Patients and Methods: A sum of 100 pregnant female with persisting placenta previa (beyond 28 weeks of pregnancy) were included in this research. Transabdominal and transvaginal ultrasonography were conducted by two separate physicians who were unaware of each other''s findings. TAS and TVS applied and analyzed unified descriptors on the placenta in order to determine its precise location. Results: At the time of Cesarean delivery, 86 individuals had unusually invasive placentas and variations, which were subsequently validated by histological study. The reliability of diagnosis of the retroplacental clear zoneloss was 76 percent by TVS and 54 percent by TAS, while that of aberrant placental lacunae was 92 percent by TVS and 88 percent by TAS. The reliability of detecting myometrial thinning was 66 percent by TVS and 72 percent by TAS. Conclusion: Transabdominal and transvaginal ultrasound have been proven to be complimentary to each other, with transvaginal ultrasound having the upper hand. The safety of TVS has also been established, and the unified descriptors have been proven to be dependable in correct diagnosis.
