Episode notes
PAS Rising with Cesarean Rates
- Placenta Accreta Spectrum (PAS) is increasing due to high cesarean delivery rates.
- This condition causes significant maternal and neonatal morbidity and mortality.
PAS Incidence and Risk Factors
- PAS incidence estimates vary widely from 0.01% to 1%, making it hard to define true prevalence.
- The main risk factor is prior cesarean delivery, making PAS largely an iatrogenic disease.
Critical Need for Early Diagnosis
- Up to 70% of accreta cases aren't diagnosed before delivery, causing missed opportunities for specialized care.
- Improving diagnostics and risk stratification in community settings is urgently needed.
