Placenta Accreta
What is Placenta Accreta?
Placenta accreta is a rare condition where the placenta remains attached to the uterine wall, potentially causing complications during delivery. Receiving a diagnosis of placenta accreta can be overwhelming, but having the right care and resources can make a difference. With CHRISTUS maternal-fetal medicine doctors, you'll receive the advanced care and support you need to navigate this journey. By focusing on your health and your baby’s well-being, we’ll help you plan for a safe delivery and the best possible outcome.
Types of Placenta Accreta
Placenta Accreta is divided into three grades:
Grade I: The placenta attaches only to the endometrium or lining of the uterus.
Grade II: The placenta goes through the myometrium or muscle layer of the uterus.
Grade III: When the placenta penetrates tissues deeper than the myometrium.
What Causes Placenta Accreta?
Placenta Accreta is caused by the placenta abnormally attaching itself too deeply and firmly to the uterus.
It typically occurs when there are scar tissues in the uterus from prior C-sections, dilation and curettage, myomectomy, or other uterine surgery procedures.
Signs & Symptoms
The most common signs and symptoms of placenta accrete include:
- Vaginal bleeding
- Abdominal pain
- Increased uterine contractions
- Prolonged labor
- Inability to deliver the baby vaginally
- A sudden drop in blood pressure
Risk Factors
Risk factors for placenta accrete include a history of:
- Prior cesarean sections
- Uterine abnormalities
- Scarring from previous surgeries
- Advanced maternal age
- Multiple gestation pregnancies
Diagnosis
Discovering placenta accreta typically occurs during an ultrasound and then confirmed through a combination of imaging tests and evaluation. During pregnancy, your doctor may use ultrasound or an MRI to identify an abnormal attachment of the placenta to the uterine wall. These imaging tools provide detailed views to help confirm the diagnosis and evaluate its severity. Early and accurate diagnosis is important to plan your care and delivery to ensure the safest outcomes for you and your baby.
Treatment
Treatment depends on the disorder's severity of the condition and your preferences for delivery. This condition may require a C-section rather than attempting a vaginal birth, to ensure the safety of both mom and baby.
Your provider will help you understand your options, and can help you choose a delivery method that is best for you.
