Effectiveness of contingent screening for placenta accreta spectrum disorders based on persistent low‐lying placenta and previous uterine surgery

A contingent screening strategy for PAS is both feasible and effective in a routine healthcare setting.

However, larger prospective studies are necessary before implementing this screening strategy into routine clinical practice. © 2020 The Authors.
