[Cervix length measured by transvaginal ultrasonography in women with twin pregnancy--prospective study].
OBJECTIVE
To evaluate cervical length in twin pregnancies measured by transvaginal ultrasonography.


METHODS
A prospective clinical study.


METHODS
Department of Obstetrics and Gynecology, Medical Faculty of Palacky, Olomouc, Czech republic.


METHODS
Clinical data of cervical length in twin pregnancies measured by transvaginal ultrasonography were summarized.


RESULTS
69% of patients delivered after 36th week of gestation, mean gestational age at the time of delivery was 35.5 week. Mean cervical length measured bi-weekly from the 16th till 34th week was 34.9, 34.6, 33.8, 33.2, 29.7, 28.7, 29.1, 28.4, 23.6, 22.8 mm. The creation of the funneling was recorded in more than 80% of patients with preterm delivery at the mean gestational age 23 week. Mean cervical length in patients delivered before 36th week was in the 23rd week of gestation 21.5 mm, while in woman delivered near term was average cervical length 33.1 mm. Genital infection in patients with preterm labours was present in 27%.


CONCLUSIONS
Transvaginal ultrasonography seems to be a useful method in antenatal care of risk pregnancies with twins.
