Placenta Accreta: Understanding a Serious Pregnancy Complication
The placenta is a remarkable organ that develops during pregnancy to nourish and support your growing baby. In most pregnancies, the placenta attaches to the wall of the uterus and then separates cleanly after birth. In a condition known as placenta accreta, however, the placenta grows too deeply into the uterine wall and does not detach as it should. This can lead to serious bleeding during delivery and requires careful planning and expert medical care.
Placenta accreta has become more common in recent decades, largely because of the rise in cesarean deliveries and other uterine surgeries. While the diagnosis can feel frightening, knowledge and preparation make an enormous difference. When the condition is identified early and managed by an experienced team, outcomes for both mother and baby are far better.
This article will help you understand what placenta accreta is, how it is diagnosed, how it is treated, and the unique halachic considerations that may arise. If you or someone you love has received this diagnosis, please know that you do not have to navigate it alone.
What Is Placenta Accreta?
Placenta accreta is part of a group of conditions sometimes called the "placenta accreta spectrum." These conditions describe how deeply the placenta has invaded the uterine wall:
- Placenta accreta: The placenta attaches too firmly to the surface of the uterine muscle.
- Placenta increta: The placenta grows into the muscle of the uterus.
- Placenta percreta: The placenta grows all the way through the uterine wall and may reach nearby organs, such as the bladder.
In each of these situations, the placenta cannot separate normally after birth. Attempting to remove it can cause severe, sometimes life-threatening bleeding. For this reason, the condition demands specialized attention and advance planning.
Key Points to Know
- Placenta accreta is a leading cause of severe bleeding (hemorrhage) during childbirth.
- Prior cesarean delivery is the most significant risk factor.
- Early diagnosis through ultrasound allows for safer, planned delivery.
- Treatment often involves a planned cesarean delivery, sometimes combined with hysterectomy.
- Delivery at a hospital with experience in managing this condition greatly improves safety.
What Causes Placenta Accreta?
Placenta accreta usually develops where the lining of the uterus has been damaged or scarred. When the normal uterine lining is disrupted, the placenta can attach more deeply than it should. The most common cause of such scarring is previous surgery on the uterus.
Common Risk Factors
- Previous cesarean deliveries — the risk increases with each additional cesarean.
- Placenta previa — when the placenta covers or lies near the cervix, especially if there has been a prior cesarean.
- Previous uterine surgery, such as fibroid removal or certain procedures following miscarriage.
- Advanced maternal age.
- Multiple prior pregnancies.
Having one or more risk factors does not mean you will develop placenta accreta, but it does mean your care team should monitor you closely.
How Is Placenta Accreta Diagnosed?
In many cases, placenta accreta is identified before birth during a routine ultrasound, particularly in women who have had a prior cesarean or who have placenta previa. Detailed ultrasound imaging can often show signs that the placenta has grown too deeply.
When the ultrasound findings are unclear, an MRI may be used to give a more detailed picture, especially to determine whether the placenta has reached nearby organs. In some situations, the condition is only discovered at the time of delivery, which is why early prenatal care and thorough monitoring are so important.
How Is Placenta Accreta Treated?
The goal of treatment is to protect the mother from dangerous bleeding while ensuring the baby is delivered safely. The right approach depends on how deeply the placenta has invaded, the location of the placenta, and your own wishes regarding future pregnancies.
Planned Cesarean Delivery
Most women with placenta accreta deliver by a scheduled cesarean, usually somewhat earlier than the due date to reduce the risk of unexpected bleeding or early labor. Planning the delivery in advance allows the medical team to prepare blood products, surgical specialists, and intensive care support.
Hysterectomy
In many cases, the safest treatment is to remove the uterus (hysterectomy) at the time of cesarean delivery, leaving the placenta in place rather than trying to detach it. While this means that future pregnancies will not be possible, it is often the most effective way to prevent severe bleeding and protect the mother's life.
Uterus-Preserving Approaches
In carefully selected situations, specialized centers may attempt approaches that aim to preserve the uterus. These options carry their own risks and are not appropriate for every patient. They should be discussed in detail with an experienced maternal-fetal medicine specialist.
Halachic Perspective
A diagnosis of placenta accreta can raise deeply personal and weighty halachic questions. Because the condition may involve a planned hysterectomy, families often grapple with the loss of future fertility, the timing of an early delivery, and the prioritization of the mother's safety.
In Jewish law, the preservation of the mother's life (pikuach nefesh) is of paramount importance, and the protection of her health and safety is given the highest priority. When the medical team recommends an early delivery or a hysterectomy to prevent life-threatening hemorrhage, these recommendations are generally consistent with halachic values that place a mother's life above other considerations.
At the same time, decisions surrounding the timing of delivery, the choice between uterus-preserving and definitive surgery, and the emotional weight of ending one's childbearing years deserve careful, compassionate guidance. These are not questions to face alone. Bringing your rabbi and medical team together can help you make decisions that honor both your health and your values.
Specific questions should be discussed with a qualified rabbinic authority. Our team at PUAH is available to help you navigate these questions.
When to Speak With a Professional
If you have a history of cesarean delivery, uterine surgery, or have been told you have placenta previa, speak with your doctor about your risk for placenta accreta. Once a diagnosis is made, it is essential to arrange care at a hospital experienced in managing this condition.
Seek immediate medical attention if you experience vaginal bleeding during pregnancy, severe abdominal pain, or contractions before your scheduled delivery. These may be signs that require urgent evaluation.
Beyond the medical decisions, a diagnosis like this carries real emotional and spiritual weight. PUAH's team of doctors and rabbis specializes in exactly these situations — helping families coordinate expert medical care while addressing the halachic and emotional dimensions of their journey.

Summary
Placenta accreta is a serious condition in which the placenta attaches too deeply to the uterine wall, creating a risk of severe bleeding at delivery. With early diagnosis, careful planning, and an experienced medical team, outcomes for mother and baby are greatly improved. Combining trusted medical care with thoughtful halachic guidance can help you face this diagnosis with clarity, confidence, and support.
