Recurrence risk for PAS in subsequent pregnancies is approximately what percent?

• A. Up to 25%
• B. Up to 5%
• C. Up to 50%
• D. Up to 75%

Answer: (A)

Recurrence of placenta accreta spectrum in a later pregnancy remains higher than in the general population, but it’s not overwhelmingly likely. After a prior PAS, the chance of PAS recurring in a subsequent pregnancy is up to about one in four, or roughly 25 percent. This reflects the enduring uterine scar and the tendency for placental tissue to invade abnormally near scarred areas in future pregnancies. The risk rises somewhat with additional factors such as more prior cesarean deliveries or placenta previa, but even with those factors the typical recurrence rate centers in the mid-20s rather than reaching 50% or 75%. When counseling, emphasize that a notable minority may face PAS again, so early prenatal imaging and planning for delivery at a specialized center are important.
