Overview
Diagnosis
If you have risk factors for placenta accreta during pregnancy, such as placenta previa or a history of uterine surgery, your healthcare provider will carefully assess how the placenta is implanted.
Imaging tests like ultrasound or magnetic resonance imaging (MRI) can help evaluate the depth of placental implantation in the uterine wall.
Treatment
When placenta accreta is suspected, your healthcare provider will create a plan to safely deliver your baby. Treatment options may include:
• Cesarean hysterectomy – In cases of extensive placenta accreta, a C-section followed by removal of the uterus may be necessary. This procedure prevents severe, potentially life-threatening bleeding.
• Hospitalization or pelvic rest – If vaginal bleeding occurs during the third trimester, your provider may recommend monitoring in the hospital or restricting activity.
Before surgery, your healthcare team may include:
• Obstetrician and gynecologist
• Pelvic surgery subspecialists
• Anesthesia team
• Pediatric team
Your provider will discuss potential risks, including the need for blood transfusions or intensive care admission due to severe bleeding.
During surgery, the baby is delivered through an abdominal and uterine incision, and the uterus with the placenta attached is removed to prevent major hemorrhage.
In rare cases, the uterus and placenta may be left intact to allow the placenta to dissolve naturally, but this can lead to:
• Severe vaginal bleeding
• Infection
• Possible need for a later hysterectomy
Avoiding a hysterectomy after placenta accreta may increase the risk of complications in future pregnancies, including recurrent placenta accreta.
