Final answer:
The risk of placenta accreta increases with the number of previous cesarean sections a woman has undergone.
Step-by-step explanation:
The risk of placenta accreta increases with the number of previous cesarean sections (CS) a woman has undergone. The risk levels are as follows:
- a. No previous CS: Low risk
- b. 1 previous CS: Moderate risk
- c. 2 previous CS: Higher risk
- d. 3 or more previous CS: Very high risk
Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall. It can cause severe bleeding during delivery and may require a hysterectomy. The condition is more likely to occur in women who have had multiple cesarean sections.
