Parietococcygeal Length

The pariecoccygeal length (TCL) is the length of the human embryo from the crown (top of the head) to the coccyx (lower spine). TCD is an important indicator of fetal development and can be used to determine normal fetal development during pregnancy.

During fetal development, TCD increases in accordance with the growth and development of the fetus. At the beginning of pregnancy, the length of the fetus is about 2.5 cm, and at the end of pregnancy it is about 40 cm. However, TCD may vary depending on factors such as maternal nutrition, genetic factors, maternal health status, etc.

TCD measurement is carried out in the early stages of pregnancy, when there are no visible changes in the development of the fetus. This allows us to determine the presence of possible developmental problems, such as fetal growth restriction or the presence of hereditary diseases.

In addition, TCD measurements can be used to determine gestational age, which is important for making decisions about the need for additional testing or treatment.

Thus, TCD measurement is an important tool for assessing fetal development and identifying possible developmental problems.

Parietococcygeal size

When a baby is born, it is surrounded by an umbilical cord, which connects it to the placenta, which in turn connects to the wall of the uterus. Although this connection is physiological, it is potentially dangerous for new parents, as some components of the umbilical cord can harm their growing baby. Typically, the umbilical cord contains three blood vessels that supply the baby with oxygen and nutrients: one in the back of the heart and two in the front of the fetus. The umbilical end also has a sac called the amnion, which contains fluid that the doctor uses for testing. Although this liquid is rich in nutrients for the fetus, it is often considered a contaminant due to its unstable pH. If not removed, it may cause infection in the child due to unfavorable pH, which will be exposed to contamination from bacteria associated with a lack of sterility. The doctor may remove about 215 ml of fluid at one stage of pregnancy, as this is the average amount that can be safely removed during pregnancy.
