What is the primary purpose of prophylactic cervical cerclage during pregnancy?

The primary purpose of prophylactic cervical cerclage during pregnancy is to prevent premature cervical dilation. This procedure involves placing a stitch around the cervix to provide additional support, particularly in cases where there is a risk of cervical incompetence. Cervical incompetence can lead to premature birth due to the inability of the cervix to remain closed as the pregnancy progresses.

By placing a cerclage, healthcare providers aim to stabilize the cervix and prevent it from opening too early, thus reducing the risk of preterm labor and improving outcomes for both the mother and the developing fetus. This intervention is especially beneficial for women who have a history of cervical insufficiency or have had previous preterm deliveries.

Enhancing fetal nutrition, inducing labor, or monitoring fetal heart rate do not align with the primary intent of the cerclage, making them less relevant in the context of this procedure.
