“…Although it is uncertain if the observers were blinded to the ultimate diagnosis, there were no cases without PAS and loss of clear zone was seen in every case. Kliewer et al 21 . recently reported kappa values of 0.77 for intraplacental vascular cluster and 0.59 for traversing vessel in a cohort of 32 patients at risk of PAS.…”

Kliewer et al 21 recently reported kappa values of 0.77 for intraplacental vascular cluster and 0.59 for traversing vessel in a cohort of 32 patients at risk of PAS. Most cohort studies do not describe the intraoperative and histopathologic findings at birth 13 , and it is therefore difficult to assess the accuracy of the diagnosis of PAS.…”

What are the novel findings of this work?Correlation of prenatal ultrasound assessment suggestive of placenta accreta spectrum (PAS) at birth with histopathologic confirmation is very strong. However, interobserver agreement of preoperative ultrasound assessment with histopathologic confirmation of PAS is only moderate. Morbidity is associated with both histopathologic diagnosis and antenatal assessment indicative of PAS. What are the clinical implications of this work?Concordance of ultrasound features and histopathology is not absolute. The most useful signs are placental lacunae and increased subplacental vascularity. Agreement was poor for myometrial thinning, loss of clear zone, bladder wall interruption, placental bulge and bridging vessels.
