The term "chorion" is used by obstetricians-gynecologists to refer to the placenta in the first trimester of pregnancy. Chorionic presentation is a pathological condition that can lead to undesirable consequences.
What is chorionic presentation
Chorion is the villous membrane of the ovum, which ensures its growth and development. During the normal course of pregnancy, it is implanted into the inner lining of the fundus of the uterus, and then into the anterior, posterior and lateral walls. Chorionic presentation implies its incorrect location. It does not attach to the body of the uterus, but captures its lower segment. Sometimes there is a complete or partial overlap of the internal os of the cervical canal coming from the uterus. This diagnosis is most dangerous in the early stages of pregnancy. Usually, as the fetus grows, the placenta rises up, but in some cases this does not happen.
When presentation occurs
The reasons for the development of this pathological condition are not fully understood. However, several factors have been identified that contribute to the incorrect location of the chorion. Among them are chronic inflammatory diseases of the uterus, postoperative scars, fibroids, abnormalities in the development of the uterus and a large number of births in the anamnesis.
Symptoms of the wrong location of the chorion
As a rule, this pathology is diagnosed during a routine ultrasound scan in the absence of any complaints from the woman. There are cases when presentation is accompanied by bleeding from the genital tract against the background of complete well-being. Usually, external factors such as excessive physical activity, intercourse and taking a hot bath contribute to their development.
Possible complications
Chorionic presentation is one of the most serious obstetric problems that can lead to a number of complications from the fetus and mother. These include termination of pregnancy, intrauterine growth retardation and fetal death, severe anemia in a woman with frequent bleeding.
Chorionic presentation treatment
There is no specific treatment for this pathology. Therapeutic measures are aimed at preventing abortion and treating possible complications. When diagnosing chorionic presentation during an ultrasound scan, a woman is offered a complex of therapeutic measures in a hospital setting. She is recommended strict bed rest, ultrasound control, taking medications to reduce the tone of the uterus and vitamins for pregnant women. When discharging home, a pregnant woman should exclude physical activity, stressful situations and sexual intercourse. The appearance of bloody discharge is the reason for an emergency appeal to the gynecological department and the appointment of hemostatic drugs. With massive bleeding that threatens the condition of a woman, an abortion is performed.
