Placenta accreta spectrum (PAS) used to be a rare pregnancy condition, but it now affects roughly 14,000 pregnancies annually, posing a major cause of maternal death. Yet why it happens is still not well understood. Placenta accreta occurs when the placenta grows too deeply into the uterine wall, and doesn't detach after birth, often resulting in life-threatening bleeding and a need for a hysterectomy.
