placenta is provided by nature specifically for growth and development of the fetus Fetal development - week after week .No wonder in Latin her name means "children's place."For normal pregnancy it is important not only the structure but also the location of the body.However, the diagnosis of "marginal placenta previa" - is not a reason to become despondent.It only means that the expectant mother should be closely concern the health.
How is placenta
brief appearance of the mechanism can be described as the placenta.Once in the uterus, the fertilized egg is immersed in her mucous membranes like a ball into a thick cream.By the ninth day of the embryo are formed on the surface of the villi, which grow in the uterine wall.Subsequently, one starts to develop and placenta.The final formation of the body comes to the 13-16 week of pregnancy.
The form the placenta is like a flat disk, which is attached to the center of the cord.Inside this disc is incredibly important for the baby's process
What is marginal placenta previa
Normally, the placenta is formed in the upper part (the "bottom") of the uterus along its back, side or less of the front wall.This provision protects it from accidental injury.
About previa Authority (placenta praevia) say, when it is formed in the lower part of the uterus near the outlet - shed.Literally this term translates from Latin as "the path to life", that is, the placenta becomes an obstacle to the emergence of the baby born.
There are three types of previa:
- total (placenta covers the mouth of 100%),
- side (hole blocked at 50-70%),
- edge (output is closed no more than 30%).
Of all the options considered marginal previa most prosperous, as in this case there is a high probability that the birth will take place naturally.Pathology is usually detected during a routine of ultrasound.
Who is at risk?
In most cases, the correct position of the placenta is associated with pathological changes of the inner layer of the uterus.Because of this, the fertilized egg can not "catch" the top of the endometrium and comes down.
causes of these states can be:
- surgeries that preceded the current pregnancy (curettage, cesarean section, removal of benign nodes),
- infections, sexually transmitted infections,
- inflammation of the cervix.
of pathology may also be due to congenital abnormalities of the uterus or fibroids that caused its deformation.
multiparous marginal previa is diagnosed three times more often than women, who will be the birth of first child.Perhaps this is due to the fact that my mother experienced at the time of the second and third delivery time to move a larger number of gynecological diseases.
risk of complications
The dangerous marginal placenta previa?In the early stages of nothing.The kid is growing and developing normally.Mom her pathology could not feel.
Problems can occur in the third trimester when the uterus is greatly increased in size.Placental tissue flexible enough, so she does not have time to stretch after the endometrium.In some places the body is peeled from the walls of the uterus, leading to vascular damage.The blood flows out through the cervical canal.
fruit at the same time does not suffer.However, too frequent bleeding starts to receive less oxygen, because loose particles placenta cease to function.
can provoke bleeding:
- sexual contact,
- hot procedures (bath, sauna),
- examination by a gynecologist,
- straining stomach.
At the regional allocation previa discharge in women when there is cause for concern not abundant, painless.Sometimes, for no reason, they appear at night.
Bleeding may begin in the last weeks of pregnancy.But in most cases they do not bother the woman up to the onset of labor, when sharply increased uterine activity.
Sometimes the boundary presentation is accompanied by malposition - oblique, pelvic or cross.In this case, the birth process may be complicated.
observation and treatment
In the early stages patients observed outpatients.No medical treatment is not carried out.Women recommends:
- avoid stress, exercise, sexual intercourse,
- comply competent diet,
- fully relax.
It should be noted that the final diagnosis only occurs closer to birth.Until that time there is likely that the situation will change to a normal placenta.It is connected with the same increase in the size of the uterus.Stretching, endometrium pulls the placenta, and the edges are shifted to the throat area.
When bleeding Spotting - it is important to rule out pathology patient hospitalized and further monitoring is carried out in a hospital.
What will happen at the regional delivery placenta previa, the doctor decides on the last weeks of gestation.In the presence of associated complications (polyhydramnios, narrow pelvis, kidney disease, scarring of the uterus) is performed a caesarean section.When well-being of women opt for the natural childbirth.If
before labor in a pregnant woman bleeding occurs, it reveal the fetal bladder.This is to prevent further detachment of the placenta, and helps stop discharge.If you can not stop the bleeding, childbirth is completed surgically.
prerequisite of delivery is a continuous monitoring of the woman and baby.On the abdomen the patient attached sensors, which detect the fetal heartbeat.
After the baby's birth and may develop severe bleeding.In this case, doctors have to resort to surgical removal of the placenta.
