Placenta accreta and previa: what to know

How the structures involved in Placenta Accreta differ from normal
Illustration: How the structures involved in Placenta Accreta differ from normal

Short answer

Placenta accreta and placenta previa are different placental conditions that can overlap and need specialist birth planning.

This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

At a glance

Previa
A low placenta near or over the cervix.
Accreta
Placenta attached more deeply than usual.
Planning
Bleeding symptoms should be reported promptly.

What these terms mean

Placenta previa means the placenta lies low in the uterus and may cover or approach the cervix, the opening to the vagina. Placenta accreta spectrum means the placenta is attached more deeply than usual and may not separate normally after birth. The depth of attachment can vary. A low placenta does not by itself establish accreta, and an ultrasound concern is not the same as a confirmed diagnosis.

The combination matters because a placenta close to the cervix can bleed, while abnormally deep attachment can cause heavy bleeding when the placenta is disturbed. A previous caesarean birth can be relevant to placental attachment, so tell the maternity team about prior uterine procedures.

How care is planned

Keep scheduled antenatal scans and ask whether the placenta has moved away from the cervix as pregnancy progresses. If accreta is suspected, care is usually coordinated by an experienced obstetric team with access to blood products, anaesthesia, surgery and newborn support. The timing and method of birth depend on scan findings, bleeding, pregnancy progress and your individual history.

A planned caesarean section may be advised when placenta previa remains, and accreta planning may include avoiding an attempt to pull the placenta away. In some cases, hysterectomy is discussed after the baby is born; this means removing the uterus and ends the ability to carry a future pregnancy.

When to seek urgent care

Contact your maternity unit urgently for any vaginal bleeding during pregnancy, especially if it is fresh, heavy, recurrent or accompanied by cramps, contractions, dizziness or reduced fetal movement. Call emergency services if you feel faint, weak, short of breath or unwell, or if bleeding is heavy. Do not wait for a routine appointment to report bleeding.

Useful questions for your doctor

Ask where the placenta is in relation to the cervix, whether the scan shows signs of accreta, which hospital should provide your birth care, and what symptoms should trigger immediate attendance. You can also ask how a caesarean section or hysterectomy might fit into the plan.

Questions people ask

Can placenta previa and accreta occur together?

Yes. They are separate conditions, but a low placenta can coexist with abnormal placental attachment and may change birth planning.

Does every low placenta cause bleeding?

No. Some people have no bleeding, but any bleeding in pregnancy should be assessed by the maternity team.
