What Is Circumvallate Placenta? Everything You Need To Know

Expert validation


The circumvallate placenta is an abnormal problem in the shape of the placenta. It can lead to an absence of nutrients for the fetus. The placenta plays an essential role during pregnancy.

The placenta forms during pregnancy and attaches itself to the uterus wall around 6 to 10 days after conception. It offers a growing child oxygen and nutrients. A healthy placenta is essential for a healthy pregnancy.

If the placenta does not create properly, then it could impact the child’s growth. Placental problems such as circumvallate placenta can influence the health of the growing baby.

Circumvallate placenta is very rare and can be identified in an ultrasound. Continue reading to understand more concerning this condition.

The chorionic plate, which is the part of the placenta on the fetal side, is too small. That causes the membranes to double back on the fetal side and around the edges.

The condition can be spotted by ultrasound and is generally detected around the 20th week of pregnancy. Nevertheless, diagnosis during pregnancy can be difficult as well as the condition is often not spotted up until the placenta is detected following delivery.

Circumvallate placenta is very uncommon, occurring in around 1 to 7 percent of pregnancies.

What Is Circumvallate Placenta?

When the growth of the placenta results in an abnormal shape, it is called the circumvallate placenta. Below, the chorionic plate of the placenta is too small. When the chorionic plate is small, the membrane layers of the fetal side double back throughout growth. It happens around the sides of the placenta. This will occasionally cause the unborn child to obtain fewer nutrients.

There are times when doctors don’t observe this problem during pregnancy and would certainly see it just after the delivery. The diagnosis is challenging, and the problem can be detected throughout ultrasound scans, around 20 weeks of pregnancy.

Are there symptoms or warning signs of Circumvallate Placenta?

There aren’t any type of indications or symptoms of the circumvallate placenta. The condition can trigger a decreased supply of blood and nutrients to the unborn child. This may trigger your baby to grow at a slower pace than anticipated. There are lots of possible reasons for delayed fetal development or growth retardation, consisting of:

  • Chronic conditions in the mother, such as persistent kidney condition or diabetic issues.
  • Chromosome irregularities in the infant.
  • Expecting multiple babies at the same time.
  • Infection in the mother.

If your healthcare provider notices that your child is not progressing as expected, they will run additional examinations to determine a hidden reason, including ultrasound and blood tests.

What Causes Circumvallate Placenta?

The exact factor for why it takes place and what creates it is not yet known to doctors. If you’ve been diagnosed with this problem, the least you can do is take a rest and eat healthily.

Who Can Get Circumvallate Placenta?

The Circumvallate placenta has been located in women of every age, race, and geographical place. There is no real defining element of who is more likely to get it. It has been seen that around 1% of expecting ladies are likely to create it.

Circumvallate Placenta Signs and Symptoms.

While circumvallate placenta does not always create signs and symptoms, some women experience some pregnancy issues that lead their doctors to feel like circumvallate placenta may be possible. Below are a few signs that you may have circumvallate placenta:

Slow-moving Foetal Growth.

When a mother has a circumvallate placenta, the development of the fetus often tends to be slower. You will certainly need to do the testing to determine why your baby does not reach the growth milestones during your regular check-ups. Usually, your doctor may try to rule out circumvallate placenta via an ultrasound. With a closer look, it can be verified if you have it or not.

Bleeding From the Vagina.

Throughout the initial trimester, some ladies experience even more bleeding from the vaginal area than is typical. A research study was conducted that concluded that vaginal bleeding was more common in females who had circumvallate than in others.

The research study was performed taking into account the data of a small number of women, so this might not be an excellent representation of all women that create circumvallate placenta.

Premature Rupture of Membranes.

Premature Rupture of Membranes (PROM) is another possible indication of the circumvallate placenta. PROM takes place with the early rupture of the amniotic sac. When this occurs prior to labour or when a woman has gotten to 37 weeks of pregnancy, it is referred to as the preterm premature rupture of membranes (PPROM).

When PROM takes place together with vaginal blood loss, it is a possibility that a mother has developed a circumvallate placenta.

How Does Circumvallate Placenta Affect Pregnancy?

The circumvallate placenta can complicate your pregnancy in several of the following means:

Losing The Unborn Baby and Premature Labour

If the circumvallate placenta is extreme and not dealt with, the mother might lose the baby or go into early labor.

Placental Abruption

When the placenta is divided from the cellular lining of the womb prematurely, it is known as placental abruption. This can create a lot of blood loss and can put the mother and the baby at risk.

Reduced Birth Weight

Among the most common troubles faced by mothers who develop circumvallate placenta is that their children are born with low weight at birth. This happens due to the limited nutrition or slow growth of the fetus due to the abnormal shape of the placenta.


When there is a reduction in the amount of amniotic liquid, it is known as oligohydramnios. The amniotic fluid is helpful to the baby as it develops a pillow around it.

Fetal development also takes advantage of the liquid. The ever-important umbilical cable is protected against obtaining crushed because of the amniotic liquid. Without the umbilical cable in peak problem, your baby will not get proper nutrients or oxygen.

The circumvallate placenta is hard to identify. Nonetheless, there are times when doctors may discover that the placenta has actually been created extraordinarily during routine exams and ultrasounds. This is actually the only way to diagnose circumvallate placenta.

In some cases, if a mother reveals some of the signs and symptoms, the doctor may check for the signs of the circumvallate placenta. At other times, no one knows that they have a circumvallate placenta, and also, delivery is the only time it is made known.

Treating Circumvallate Placental Complications

If you develop a circumvallate placenta, doctors can not fix your placenta. But they can help with handling it. Here are some ways in which your doctor can aid you to cope with the difficulties that can occur out of the circumvallate placenta:

Placental Abruption

If you lose blood as an outcome of the fractured placenta, IV fluids that help boost blood stress may need to be given. If it is not time for your baby to be born, bed rest is recommended.

Sadly, some women have very severe blood loss, causing them to deliver the baby right away. If either the child or the mother’s life is at risk, it results in an emergency C-Section.

Intrauterine Restricted Growth

There is no therapy for this, yet your doctors will be able to aid you in managing this problem. Your child’s growth will surely need to be kept an eye on a lot more than normal. You will certainly be advised to ensure that your diet plan is effectively balanced and packed with nutrients, and will be asked to relax well and also live a much healthier lifestyle. You will need to stop the consumption of tobacco if you are a smoker.


Women that have low amniotic acid will require even more monitoring. There is a therapy that will require to be taken on referred to as “Amnioinfusion.” Here, the liquid is put inside the amniotic cavity to make sure that the liquid lost can be replaced. By doing this, the risk of the umbilical cord getting crushed or the risk of the lungs being underdeveloped may decrease.

Is Vaginal Delivery Possible in Case of Circumvallate Placenta?

There are plenty of circumstances when a mother might require to go through an emergency C-Section in the case of the circumvallate placenta; this is not always the situation. Circumvallate placenta outcomes vary from person to person as well as from case to case.

Many mothers have actually been able to have a normal delivery. The first thing that will surely happen is that you will be very closely monitored if you are diagnosed with the circumvallate placenta. Your baby’s progress will be checked. This is all to guarantee that every little thing is going smoothly.

Doctors will only intervene if they think they are needed. Trying and taking care of the case to help things move efficiently so that a normal vaginal birth can take place is always the first option.

Can It Be Prevented?

There is currently no actual way to stop circumvallate placenta as the reason is not yet known. The only thing that can be done is to make sure that moms that have actually been diagnosed take good care and follow the instructions provided to them by their doctor.


Circumvallate placenta is a very unusual condition. Fortunately, many moms have actually handled having their kids with no real issues, despite the problem. In the much less lucky instances, the problem leads to other difficulties that make normal delivery impossible.

Circumvallate placenta risks the life of the mother and the baby if not managed well. So if you have been detected, simply keep in mind to seek advice from your physician routinely and follow all the guidelines.

Following your physician’s advice is the very best option that you can do for your baby’s wellness and your health. There is absolutely nothing known that develops circumvallate placenta; there is no way to suggest exactly how to avoid it from happening.

Your child needs you, so make sure to maintain your health and wellness in check. This is the one way pregnant ladies can wish for a problem-free pregnancy that results in a smooth delivery.

The Bottom Line

Circumvallate placenta is connected with a greater risk of some pregnancy complications and also, sometimes, can lead to the loss of your baby. This problem is extremely rare and does not always result in the loss of a baby. Proper management, treatment, and therapy will significantly improve results.
