Which of the following is the most important risk factor for placenta accreta spectrum?

• A Advanced maternal age
• B Hypertensive disorders of pregnancy
• C Multiparity
• D Previous cesarean section with placenta previa ✓

Explanation

The strongest risk factor for placenta accreta is placenta previa in a woman with a previous cesarean section. The combination of a scarred uterus and placenta implantation over the scar dramatically increases invasion risk. Advanced maternal age and multiparity are minor risk factors. Hypertensive disorders are not directly associated with accreta.
