The cervical length scan, also known as cervical ultrasound, is typically conducted in the second and third trimesters of pregnancy. It helps assess the length and condition of the cervix, which is the lower part of the uterus that connects to the birth canal.

The scan is performed using ultrasound technology. A healthcare professional will use a transvaginal ultrasound probe to obtain images of the cervix. By measuring the length of the cervix, they can determine if it is within the normal range or if there is a risk of cervical insufficiency or premature cervical shortening.

The assessment of cervical length is important because a short or weakened cervix can increase the risk of premature labor or preterm birth. If a shortened cervix is detected, additional monitoring or interventions may be recommended to prevent or manage preterm labor, such as cervical cerclage (a surgical procedure to reinforce the cervix) or progesterone supplementation.

It’s worth noting that the cervical length scan is not a routine screening test for all pregnancies but may be suggested based on certain risk factors or previous obstetric history. It is typically recommended for women who have a history of preterm birth, previous cervical procedures, or other risk factors that may predispose them to cervical insufficiency.

If you have specific concerns or questions about cervical health during pregnancy, it is best to consult with your healthcare provider or obstetrician who can provide personalized guidance and address any concerns you may have.
