Study Notes
Risk Factors for Placenta Previa
- Previous cesarean deliveries elevate the risk of placenta previa due to scarring and altered uterine structure.
- Multiple pregnancies (twins or more) increase the likelihood of placenta previa.
- Maternal age over 35 is linked to a higher risk of developing this condition.
- History of uterine surgery or abnormalities raises susceptibility to placenta previa.
Symptoms During Pregnancy
- Painless vaginal bleeding during the first and second trimesters may indicate placenta previa.
- Bleeding associated with placenta previa can be sudden and is a cause for immediate medical attention.
Age Factors
- Women aged 35 and older are at a higher risk for developing placenta previa, in part due to biological changes associated with advanced maternal age.
Assisted Reproductive Technology
- Use of assisted reproductive technology (ART), such as in vitro fertilization (IVF), is associated with a greater chance of placenta previa due to the multiple embryos that may implant.
Causes of Bleeding
- The principal cause of bleeding in cases of placenta previa is the placenta's location near or over the cervix, which can lead to detachment or irritation.
Risks to the Baby
- A baby may be at risk for preterm birth in cases of placenta previa, potentially leading to complications related to prematurity.
Risks to the Mother
- Mothers can experience significant hemorrhaging, which may require blood transfusions or emergency medical intervention.
Placenta Invasion
- If the placenta invades deeply into the uterine wall, the condition known as placenta accreta can occur, complicating delivery and increasing the risk of severe hemorrhage.
Placenta Abruptio Concerns
- Placenta abruptio, or placental abruption, can be a serious concern when dealing with placenta previa, leading to heavy bleeding and requiring urgent care.
