What is a risk associated with multiple cesarean sections?

Having multiple cesarean sections increases the risk of placenta previa, which is a condition where the placenta partially or completely covers the cervix. This complication is particularly concerning because it can lead to significant bleeding during delivery, necessitating careful management and often leading to planned cesarean delivery to avoid complications.

The risk of placenta previa rises with each subsequent cesarean, primarily due to the changes that occur in the uterine lining after surgical interventions. Scar tissue formation and alterations in the normal structure of the uterus can contribute to abnormal placentation, increasing the likelihood of previa.

The other options reflect outcomes that do not align with the established risks associated with multiple cesarean deliveries. For instance, there is no increase in the chance of vaginal delivery, nor is there a decreased risk of hemorrhage. In fact, the risk of hemorrhage generally increases with multiple cesareans due to factors such as uterine atony or the presence of abnormal placentation. The likelihood of ectopic pregnancy is unrelated to previous cesarean sections and is influenced more by factors such as prior pelvic surgery or existing tubal disease.
