[Usefulness of ultrasonography of the cervical canal in the screening of pregnant women at risk of premature labor].
BACKGROUND
Goal of the study is to evaluate the utility of cervical sonography in the second quarter as screening of pregnancies with risk of preterm labor.


METHODS
A.A. evaluate, by transvaginal sonography (TVS) of the uterine cervix, 75 pregnancies with history of preterm labor and 25 with risk of preterm labor between XXIV and XXXIII week of pregnancy. The uterine cervix length < 40 mm and width > 5 mm, funneling were pathological and predictive factors of preterm labor.


RESULTS
Eighty-five percent of pregnancies that have, at sonography TVG, abnormal values of length and width of uterine cervix, delivered before XXXVI week.


CONCLUSIONS
These results confirm the importance of the high frequency ultrasonography transvaginal, TVS, for its predictive value and for treatment in pregnancies with risk of preterm labor.
