[Sonographic evaluation of cervical length and cervical canal width in 24th week of twin pregnancy in prediction of preterm delivery].
OBJECTIVE
Sonographic evaluation of the cervical length and cervical canal width in 24th week of twin pregnancy in prediction of preterm delivery.


METHODS
43 primiparous patients with twin pregnancy. Group I (n = 16, 37.2%) with spontaneous delivery before 36 of gestation; group II (n = 27, 62.8%) delivering in term. Sonographic measurements of the cervical length and cervical canal width were done in 24th week of gestation.


RESULTS
Mean values of cervical length in group I were: 25.6 mm (+/- 3.7 mm); and in group II--32.5 mm (+/- 6.0 mm). Corresponding values of canal width were: 14.6 mm (+/- 11.8 mm) and 6.2 mm (+/- 3.0 mm).


CONCLUSIONS
We suggest, that cervical length is more valuable parameter in predicting risk of preterm delivery in twin pregnancy.
