What is the term for the abnormal development of the placenta covering the cervix?

The term for the abnormal development of the placenta covering the cervix is placenta previa. This condition occurs when the placenta is implanted low in the uterus, either partially or completely covering the cervix. This can lead to complications during pregnancy and delivery, as the presence of the placenta over the cervix can obstruct the birth canal.

In cases of placenta previa, healthcare providers closely monitor the pregnancy, and delivery methods may be adjusted based on the degree of placental coverage and any symptoms experienced by the mother. Depending on the specific circumstances, a cesarean section may be necessary to ensure the safety of both the mother and the baby during delivery.

Other terms listed refer to different conditions. Placenta accreta is associated with abnormal adherence of the placenta to the uterine wall, often leading to severe bleeding at delivery. Placenta abruption involves the premature separation of the placenta from the uterine wall, which is a different complication with distinct symptoms and risks. Placenta infarct refers to areas of ischemic necrosis within the placenta due to inadequate blood supply. Each of these conditions has unique features and management needs, which is important for understanding the various issues related to placental health in pregnancy.
