[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.

MATERIALS AND

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.
