What type of placenta previa is completely covering the cervical os?

Complete placenta previa is characterized by the abnormal placement of the placenta such that it entirely covers the cervical os, which is the opening of the cervix. This condition can pose significant risks during labor and delivery, as it can lead to severe bleeding, obstructing vaginal delivery and potentially endangering both the mother and the fetus.

Identifying complete placenta previa is crucial for managing pregnancies, as it often necessitates planning for a cesarean delivery to avoid complications that arise from attempting vaginal birth.

In contrast, low-lying placenta previa occurs when the placenta is located close to the cervix but does not cover it, marginal placenta previa refers to the placenta being at the edge of the cervical os, and increta involves abnormal placental attachment into the uterine wall rather than its position in relation to the cervical os. Understanding the precise type of placenta previa is essential for appropriate clinical intervention and ensuring the safety of both the mother and the baby.
