Placenta accreta spectrum ultrasound: what it can show

A sonographer or specialist may assess the placenta’s position, its border with the uterus, blood flow, and the appearance of the muscle behind it. They may also look at the area near the cervix and bladder when percreta is a concern. A transabdominal scan is common; a transvaginal scan may provide a closer view when appropriate. A report can describe signs that are reassuring, suspicious, or unclear. A normal-looking scan does not replace clinical review when other features or pregnancy history raise concern.

Take the written report to your obstetric team and ask what each finding means for your pregnancy. Further expert imaging may be suggested if the placenta is difficult to assess or the result is uncertain. The team may coordinate a caesarean section at a hospital with surgical, anaesthetic, blood-bank, and neonatal support. They can also explain why a hysterectomy might be planned and what alternatives, if any, fit your circumstances. Keep scheduled reviews even when you feel well.

Seek urgent maternity assessment for any vaginal bleeding, painful tightening, leaking fluid, severe abdominal pain, faintness, or reduced fetal movement. Heavy bleeding or feeling as though you may collapse requires emergency help. Mention the ultrasound concern immediately when contacting the hospital so the right team can be alerted.

Ask whether the placenta overlaps the cervix or a uterine scar, which ultrasound signs were seen, whether specialist review is needed, and whether magnetic resonance imaging would change planning. Ask when and where birth is recommended and what symptoms should bring you to hospital.
