PURPOSE: to identify characteristics common to women who suffer from cervical incompetence (CI) allowing their early identification and helping in the follow-up of the gestational-postdelivery cycle. PATIENTS AND METHODS: fifty pregnant women suffering from CI and submitted to uterine cerclage according to modified McDonald's technique were analyzed in an observational descriptive study. The following variables of the medical records were evaluated: age, preceding obstetrical aspects, time of CI diagnosis, cerclage-related aspects and preterm delivery incidence. RESULTS: the average age of the mothers was 29.28 years and mean number of previous gestations was 3.76. As to the preceding obstetrical aspects, 189 gestations with a CI diagnosis were reported and cerclage had been applied to 18 of them, resulting in 18 babies who were born alive (8 preterm deliveries and 10 term deliveries). Of the 171 previous pregnancies in which CI diagnosis was not reported, 90 progressed to abortion, 68 were preterm and 13 were term deliveries. In 30 (60%) patients, CI was diagnosed during the intergestational interval, and 20 (40%) during gestation. The average gestational period in which patients were submitted to cerclage was 18.29 weeks; 40% of the cerclages were emergency procedures and 60% were elective. The incidence of prematurity was 30% (15/50). CONCLUSION: careful obstetrical evaluation of multiparous women, presenting recurrent miscarriages, during the intergestational interval and/or during the first trimester of pregnancy, may allow the early diagnosis and adequate treatment of CI, avoiding prematurity.
