5 Inredible Facts About Circumvallate Placenta: Cause, Treatment, Risks


Circumvallate Placenta

Circumvallate Placenta:

Circumvallate placenta is a condition in which variation occurs in placental morphology, due to the result of small chorionic plate and chorion fetal membranes doubling around the edges of the Placenta.

The Circumvallate placenta is a rare condition that arises when the placenta's chorion and amnion fetal membrane fold backward around the circumferences of the Placenta.

Ultrasound can reveal this condition, or else, it may not diagnose until delivery.

In this article, we will discuss the epidemiology, pathology, Radiographic features, symptoms, and treatment of a Circumvallate Placenta and explain how it may affect pregnancy and childbirth. 


The estimation of occurrence is 1-7% .


There is an internal inclusion of membrane from the edge toward the center of the Placenta (from a deep scion of the placenta into the deciduas). Due to this excessive implantation, the Placenta covers up more than half of the fetal sac. The Placenta decreases the excessive covering to the normal ¼ by separating from the uterine wall with the resulting back folding of the fetal membrane and the placenta towards the chorionic surface.

Warning Signs and Symptoms:

Typically, A Circulvallate Placenta doesn’t cause symptoms throughout the pregnancy. However, health experts may be able to see some signs, that a woman has Circumvallate Placenta.

Signs of Circumvallate Placenta are:

1. Vaginal Bleeding:

There are higher chances of constant vaginal bleeding during the first trimester (first three months of pregnancy).

In a study that employs 92 pregnant women with a Circumvallate Placenta, experts found that these women have higher vaginal bleeding than those in the control group during all three trimesters.

However, the experts noticed that the results may not be fully representative of the general public, as the study was run with a small number of women.

2. Slow downed Fetal Growth:

A woman with Circumvallate Placenta, her fetus may grow more slowly.

During routine checkups, if a health expert noticed, a fetus is not meeting expected growth points. Probably, he or she suggests trying to determine the underlying causes.

 3. Premature Rupture of Membranes (PROM)

Premature Rupture of Membrane happens when the amniotic sac breaks before the beginning of labor and it can impact up to 8% of pregnancies. If the rupture occurs in the first 37 weeks, health experts refer to this condition as Premature Rupture of Membranes (PROM).

What Causes Circumvallate Placenta?

Circumvallate Placenta is a morphological variation of placental development. Health experts don’t know exactly what causes it, but according to them it is not caused by anything you did or didn’t do. There is no measure by which you can prevent the Circumvallate placenta.

If you have been diagnosed with this condition, you need to be extra cautious about rest and try to take a healthy diet, and put off intrauterine growth limitation.

Radiographic Features:

Antenatal Ultrasound:

Antenatal Ultrasound may illustrate the rim of chorionic tissues as an echo-dense ridge (placental shelf).

On 3D ultrasound, its appearance is similar to s tire (the “tire sign”)  

Treatment and Prognosis:

Recognized Complications are:

  • Elevated Risks of IUGR

Differential Diagnosis:

For an increased placental edge on ultrasound:

  • Part of an amniotic band close to the placenta
  • Amniotic band  (amniotic sheet)
