ZILIANTI, Mario  and  AVILAN ROVIRA, J. M. Monitoreo del borrado del cuello uterino con sonografía transperineal. Posible significancia pronóstica. Rev Obstet Ginecol Venez [online]. 2010, vol.70, n.1, pp. 4-10. ISSN 0048-7732.

Objective: To monitor uterine cervix’ length, wide and form with transperineal sonography in the last six weeks of pregnancy and their prognostic significance. Methods: In 97 normal pregnant women attending routine antenatal care at 34-40 gestational weeks, we performed 173 measurements of the length and wide of the cervix, by transperineal sonography. Setting: Grupo Médico Nova Cecil, La Trinidad. Results: Out of the 97 pregnant women 82 delivered vaginally and 15 were operated due to pelvic stenosis. In the normal deliveries, on the average, for every increase in the cervix width of 1 mm, the cervix length decreases 0,37 over the range of measurements made. Besides, the slope was statistically significant from zero. On the contrary, in the caesarean cases these changes did not were statistically significant. Conclusions: While correlation between length and wide was statistically significant in normal deliveries, this relationship was absent in the caesarean cases. These changes have prognostic significance.
