Marginal placenta praevia- Symptoms, risks and care


During pregnancy, the placenta is one of the main organs that will accompany the fetus throughout its growth inside the uterus of the mother, and until the time of delivery. During the nine months of pregnancy that will last this period, the placenta will become the source of health and provider of nutrients and oxygen from the mother, vital to ensure the survival of the baby and promote a normal delivery instead of a cesarean section.

Such is the importance of the placenta for the health of the baby during pregnancy, which will become, like the uterus, one of the organs that specialists will control with more thoroughness to avoid problems arise during pregnancy and during delivery . One of them is the appearance of posterior placenta that indicates a bad position close to the cervix, and within it we find the marginal placenta praevia.

What is marginal placenta?

When we speak of marginal placenta praevia, we are talking about one of the degrees that can present posterior placenta in pregnancy, in this case we find a placenta that is located on one of the walls of the cervix but without getting to obstruct part of the opening of the uterus. This position occurs because the placenta has begun to grow at the base of the cervix.

Marginal placenta praevia is usually detected in the third trimester of pregnancy through an ultrasound that shows the position of the placenta in relation to the uterus.

Symptoms of the marginal placenta praevia

As in all other cases of placenta praevia , such as partial or total posterior placenta, the presence of a marginal posterior placenta in pregnancy may lead to vaginal bleeding that would indicate that the placenta has touched part of the neck opening uterine, this being the only symptom that can alert us.

Bleeding is completely painless during pregnancy and may be a bright red color that is alarming, although it may appear and disappear at various stages of pregnancy or in any week. In any case at the slightest incidence it is very necessary to go to a medical center to check the state of health of the baby and the position of the placenta with respect to the uterus before delivery.

Main risks

The risks of having a marginal placenta praevia are the following:
  • Risk during pregnancy and motherhood
  • Appearance of vaginal hemorrhages.
  • In any week of pregnancy, there may be a slowdown in the baby's normal growth rate.
  • Risk during delivery by placenta praevia
  • Preterm delivery is frequent before week 37 of pregnancy.
In some cases it is necessary to perform a cesarean delivery if the health of the fetus is threatened or the bleeding may alert to a detachment of the placenta. But usually, this diagnosis does not cover the cervix, so there may be a normal delivery.

In the case of a normal or vaginal delivery, this may be longer than normal, with a high risk of bleeding.

Care for a case of marginal placenta praevia

In the case that the doctor diagnoses that the woman has a marginal placenta praevia, it will be necessary to put into practice a series of cares and recommendations to protect the baby, which imply rest and efforts in order to avoid the obstruction of the cervix and in consequence, a premature birth especially and by cesarean section. Thus, the most important care during pregnancy are:

Control of pregnancy and placenta

As of week 28 of pregnancy, which is the period in which the marginal placenta praevia is usually detected in the walls of the cervix, it will be necessary to follow an exhaustive control by medical personnel in order to control their evolution. This will involve visits every week to check that the growth of the baby and his health progresses favorably.

Take rest

It is important to keep some rest throughout the pregnancy and avoid those activities that require a lot of effort such as: carrying weight, bending over many times or performing tasks that involve standing for a long time. This situation can cause hemorrhage and intervention by emergency cesarean section.

Avoid vaginal contact

You have to avoid vaginal touch, as this can cause bleeding.
Rest must also be maintained with regard to sexual intercourse involving penetration, including up to the date of delivery, as this could increase the risk of bleeding, causing an emergency caesarean section and putting the baby's health at risk.

Treatment for the baby in motherhood

In some cases steroid injections are recommended to accelerate the maturation of the baby's lungs during pregnancy and after birth.
