  • ...As the vast majority of placenta accreta spectrum are now the consequence of low placentation into a previous caesarean section scar, TVS has an important role in the early diagnosis, follow-up, differential diagnosis between adherent and invasive accreta placentation, and management of placenta accreta spectrum.(143) Evidence level 4...

  • ...Placental lacunae give the placenta a ‘moth-eaten’ appearance on greyscale imaging and the increased vascularity of the placental bed with large feeder vessels entering the lacunae are the most common ultrasound signs associated with placenta accreta spectrum.(16,17,142,143)...

TL;DR: Maternal mortality and morbidity are reduced when women with PAS disorders, particularly the invasive forms—placenta increta or percreta—deliver in a center of excellence by a multidisciplinary care team with experience in managing the surgical risks and perioperative challenges presented by these disorders.

TL;DR: The QUADAS-2 tool will allow for more transparent rating of bias and applicability of primary diagnostic accuracy studies.
Abstract: In 2003, the QUADAS tool for systematic reviews of diagnostic accuracy studies was developed. Experience, anecdotal reports, and feedback suggested areas for improvement; therefore, QUADAS-2 was developed. This tool comprises 4 domains: patient selection, index test, reference standard, and flow and timing. Each domain is assessed in terms of risk of bias, and the first 3 domains are also assessed in terms of concerns regarding applicability. Signalling questions are included to help judge risk of bias. The QUADAS-2 tool is applied in 4 phases: summarize the review question, tailor the tool and produce review-specific guidance, construct a flow diagram for the primary study, and judge bias and applicability. This tool will allow for more transparent rating of bias and applicability of primary diagnostic accuracy studies.
