Prospective evaluation of the impact of post-cesarean section uterine scarification in the perinatal diagnosis of placenta accreta spectrum.

Remodelling of the lower uterine segment following CD scarification leads to abnormalities of the uterine contour on both ultrasound examination and intraoperatively, independently, of the presence of accreta villous tissue on microscopic examination. These anatomical changes are often reported as diagnostic of placenta percreta and our data suggest that this grade of PAS is much rarer than reported in the recent literature. Guided histological examination can improve the overall diagnosis of PAS and is essential to obtain evidence-based epidemiologic data. This article is protected by copyright. All rights reserved.
