Placenta Previa

Placenta previa is a complication of pregnancy that is very dangerous to the baby and to the mother.  Placenta previa usually occurs during the second and third trimesters of pregnancy and is a primary cause of vaginal bleeding in the second and third trimesters.  Placenta previa occurs when the placenta implants over or close to the internal cervical os.  The cervical os refers to the opening of the cervix.  The cervix is shaped like a funnel.  The internal cervical os is opening of the cervix next to the placenta. When the cervix dilates, the placenta may tear causing bleeding or hemorrhage.

There are different types of placenta previa.  Total placenta previa occurs when the internal cervical os is completely covered by the placenta. Partial placenta previa and marginal placenta previa occur when the internal os is partially covered or when the placenta is located at the margin of the cervical os.

Placenta previa is very dangerous because of the risk of uterine bleeding and disruption of blood flow to the baby.  It can cause maternal hemorrhage, hypotension (low blood pressure), and tachycardia.  Placenta previa must be carefully managed by medical providers to avoid potentially deadly complications to the mother and the baby.
