Placenta Circumvallata

Placenta circumvallata (PC) is a condition in which the placenta, that is, the organ that connects the mother and the fetus during pregnancy, is tightly attached to the wall of the uterus. This can lead to complications during pregnancy and childbirth, as well as various health problems for mother and baby.

The causes of PC can be different. One of the main reasons is a genetic predisposition to this condition. PC can also occur as a result of infection, hormonal disorders, abnormal position of the fetus in the uterus, multiple pregnancies and other factors.

Symptoms of PC may include abdominal pain, vaginal spotting, bleeding, and other symptoms associated with pregnancy. If PC is not treated properly, it can lead to serious complications such as premature birth, low birth weight, complications during childbirth and others.

Treatment for PC usually requires hospitalization. Depending on the severity of the condition, various treatments may be used, including medications, surgery, or other methods.

It is important to note that PC can only be diagnosed by a doctor based on medical examinations and tests. Therefore, if you suspect you have PC, consult a doctor for qualified help.

Placenta circumorum is a pathology in which the placenta does not completely surround and fill the uterine cavity. Instead, the placental tissue is located against the wall of the uterus, sometimes surrounded by a cushion or ring-like tissue. Although it is not considered dangerous to the health of the mother or baby during pregnancy, this type of placenta placement can cause complications associated with premature delivery and onset of labor. The definition of "placenta circumvalla" in the literature depends on the method of marking used to describe the position of the placenta. Some physicians use terms such as "placental lacunae", "placentoid lacunae", "circumcircular lacunae", "placentomegaly" and other similar ones to describe the shape and degree of deviation from the normal placenta during examination and abortion. uterine cavity during the first and second trimesters of pregnancy. Lacunal placentas can be detected both in the early stages of pregnancy and after complete attachment of the placenta in late pregnancy. They are a diagnostic reason for interest in ultrasound examination of fetuses with growth retardation due to lacunar placentas.

Determining the causes that lead to a placenta located very close to the uterine wall is difficult. This is believed to be due to blockages and obstruction of the blood vessels in preparing the placenta to absorb its oxygen. Placental attachment usually occurs within the endometrium with pronounced muscle tissue and a developed network of blood vessels. The same mechanisms determine the important role of the angle between the three layers of the myometrium, the wall of the uterus and placenta, their thickness and muscle tension. All of these factors are extremely important to ensure the flow of blood and oxygen through the placenta from the mother's blood to the umbilical cord, as well as to prevent reverse flow of blood, which can cause placental abruption and intrauterine infection. Unfortunately, at present there are no sufficiently effective methods for determining the risk of such conditions depending on the condition of the mother, the characteristics of the placenta, or the influence of extragenital risk factors.
