Cervical length estimation and assessment of premature labour risk

One of the most essential pregnancy complications is childbirth before the 32nd week of pregnancy. Most babies born before the 24th week of pregnancy die, and most babies born after the 32nd week of pregnancy survive. To assess the risk of premature birth necessary to measure the length of the cervix through the vagina. The shorter a woman's cervix, the greater the chance of premature birth.

It is possible to measure the length of the cervix:

• In the first trimester, as an addition to the OSCAR test in the 12th-14nd gestational week
• In the II trimester, as an ultrasound examination supplement for developmental disorders of the fetus in the 19th-22nd gestational week
