Transabdominal and Transvaginal Ultrasound Findings Help to Guide the Clinical Management of Placenta Accreta Spectrum Cases

( Acta Obstet Gynecol Scand. 2024;103(1):93–102. doi: 10.1111/aogs.14715) In recent years, the incidence of placenta accreta spectrum (PAS) has risen while there is no current treatment defined as the standard. The favored conservative surgery options include 1-step conservative surgery (OSCS) and triple-P surgery. Diagnosis of PAS is often accomplished through ultrasound due to ease of use, availability, and low cost. During ultrasound screening many different signs are used to examine the uteroplacental interface, abnormal lacunae, and hypervascularity. Previous studies have sought to link ultrasound signs with histopathology, but the relationship remains unclear. This study aimed to link ultrasound signs and OSCS success, in order to understand how the signs could be used as predictors.
