Definition

Noun: A medical condition occurring during pregnancy where the placenta attaches to the lower part of the uterine wall, partially or completely covering the cervix. This abnormal implantation can cause severe bleeding, especially in the third trimester, and typically necessitates delivery by cesarean section for the safety of both the mother and the baby.

Usage

Placenta previa is used as a medical term to diagnose and describe a specific pregnancy complication. - It is a countable noun (e.g., a placenta previa, cases of placenta previa). - It is often used with verbs like diagnose, have, manage, and treat.

Examples
  • The ultrasound revealed placenta previa, so her doctor recommended bed rest.
  • Severe bleeding in the second trimester is a common symptom of placenta previa.
  • Because of the placenta previa, a vaginal delivery was too risky, and a cesarean section was scheduled.
Advanced Usage
  • Placenta Previa Accreta: A more severe condition where the placenta attaches too deeply into the uterine wall, often occurring in conjunction with placenta previa. This can lead to significant complications during delivery, such as hemorrhaging.
  • Marginal vs. Complete Placenta Previa: These are subtypes describing the degree to which the placenta covers the cervical opening. means the placenta is at the edge of the cervix, while means it fully covers it.
Variants and Related Words
  • Placental Abruption (n): A different complication where the placenta separates from the uterine lining before delivery, which is distinct from placenta previa.
  • Vasa Previa (n): A rare condition where fetal blood vessels run across the cervical opening, which also poses a risk of bleeding during labor.
Synonyms
  • Low-Lying Placenta: A general term sometimes used, especially in early pregnancy, before a definitive diagnosis of placenta previa is made.
Related Phrases and Medical Terminology
  • Cesarean Delivery/Section: The standard method of delivery for most cases of placenta previa to avoid life-threatening bleeding.
