trans vaginal scan
| Your care provider may feel it is necessary to measure the length your cervix with ultrasound. This is done with an transvaginal scan, using a transducer which is specially shaped to fit inside the vagina. This measurement may be repeated during your pregnancy if there are any concerns about preterm labor or an incompetent cervix. A cervix is considered incompetent when it shortens considerably without contractions. Cervical lengths of 30mm to 40mm are normal. If your cervix is less then 20mm, it will need close watching, bedrest and maybe a stitch known as a cerclage. NEXT |
