Cervical / Cervix Length Ultrasound Scans 14-36 weeks of pregnancy

  • We offer morning, evening and weekend appointments.
  • A Cervical Scan can help determine whether you are at risk of premature or early delivery.

 

If you are at risk of premature birth, it may be useful to have a scan to assess the length of the uterine cervix. A cervical scan is usually done after an abdominal scan. This can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.

How is this scan done?

A transvaginal approach is the clearest way to best visualize the cervix.

When is this scan done?

The scan can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.

What result can I expect?

In general a cervix should measure more than 25mm at 16-21 weeks. If the cervix measures less than 25mm you should discuss it with the person looking after your pregnancy. We may recommend a further cervical scan in 2-3 weeks. If the cervix is less than 25mm there may be options to use progesterone or insert a cervical suture.

What are the indications or reasons for having this scan?

  • Previous premature delivery
  •  Loss of amniotic fluid
  • Previous cervical surgical procedures

Patient Information

Some early pregnancy ultrasound scans are performed using a transvaginal probe technique. This technique is used to view the pelvic anatomy optimally, as the ultrasound probe can transmit safe ultrasound waves more directly to the pelvic area. In later stages of pregnancy, it may be advised to perform a transvaginal ultrasound scan to have a closer look at a baby’s anatomy, or to assess the maternal cervix.

There is no clinical risk associated with performing a transvaginal ultrasound scan. Transvaginal ultrasound scans can safely be performed during episodes of vaginal bleeding. 

It is important that you understand the procedure that is associated with this examination.

The ultrasound transducer will be placed in the vagina (the probe is prepared using high grade medical disinfectant)
The transducer will be introduced with a latex / non latex type covering and sterile ultrasound gel.
It will be necessary to move the transducer from side to side, up and down and may be swivelled to obtain ultrasound images of your pelvic anatomy.
If you prefer, you may insert the transducer yourself, otherwise the person conducting the examination will do this.
A third person may be present during the examination acting as a chaperone, if required by the sonographer or yourself.
You may request the examination to be stopped at any time during the procedure.   

Transvaginal Ultrasound Consent

Below is a link to our Transvaginal Ultrasound Consent Form. This must be completed ahead of your appointment to confirm whether you consent or do not consent to having your scan performed internally.

Contraindications 

If you are a virgin (Virgo intacta; hymen intact), guidance determines that transvaginal ultrasound scans are clinically contraindicated. If you have discussed this concern with your referrer and wish to proceed with a transvaginal ultrasound scan, this type of examination can be performed.
