What is the term for abnormal placenta development that covers the cervix?

The term for abnormal placenta development that covers the cervix is placenta previa. This condition occurs when the placenta is implanted in the lower segment of the uterus and extends over the internal cervical os. This can lead to complications during pregnancy and delivery, including increased risk of hemorrhage. In cases of placenta previa, vaginal delivery may not be possible, and a cesarean section is often required to ensure the safety of both the mother and the baby.

Understanding placenta previa is crucial for managing pregnancies in which this condition is diagnosed, as it requires careful monitoring and planning for delivery. Other related conditions, such as placenta accreta and placenta increta, involve abnormal adhesion of the placenta to the uterine wall but do not specifically pertain to the location of the placenta covering the cervix.
