Comparison of cervical length measurement in the 3rd trimester using transvaginal or transperineal ultrasound
ثبت نشده
چکیده
Objective Cervical length is often measured during the third trimester, especially in cases of threatened preterm labour. The gold standard is the transvaginal (TV) approach. A transabdominal approach is an alternative but it is often difficult to achieve a satisfactory image of the cervix in the third trimester. Transperineal (TP) ultrasound is considered less invasive and could offer a reliable alternative but has never been compared to the TV approach. The aim of this study was to compare the cervical length measurement obtained with the TV or the TP approach.

To establish reference values for the cervical length (CL) measurement by transvaginal ultrasound between 20 and 24+6 weeks of gestation in a large Brazilian population. A retrospective cross-sectional study was performed with 996 singleton pregnancies.

متن کاملCervical length for predicting preterm birth and a comparison of ultrasonic measurement techniques
Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality not attributable to congenital anomalies or aneuploidy. It has been shown that a shortened cervix is a powerful indicator of preterm births in women with singleton and twin gestations - the shorter the cervical length, the higher the risk of spontaneous preterm birth. Ultrasound measurements of the cervix are a...
