Introduction: increasing prematurity has occurred at the expense of extremely premature infants, increasing the level of neonatal risk, morbidity, and demanding for obstetric and perinatal health services.Objectives: to characterize a group of pregnant women with cervical changes and the use of vaginal pessary assisted at Ramón González Coro Teaching Hospital from 2008 to 2010.Methods: a descriptive, longitudinal study was conducted to determine the utility of vaginal pessary in pregnant women with cervical changes and who were assisted at Ramón González Coro Teaching Hospital, from 2008 to 2010. Results: 166 patients were the universe of our study. They were divided into two groups, the first group included those subjects with pessary, and the second group only underwent clinical follow up. The inclusion of these subjects in each group was performed randomly. Two out of ten pregnant women showed a normal measurement of the cervix. Almost half of the patients received the pessary cerclage, which was placed at 29- 33 weeks, 4 out of 10 women had it at 26 and 28 weeks; and only 14.6 % of patients received it before week 26.Conclusions: more than half of these pregnant women were nulliparous. The best represented risk factor was three or more induced abortions. Half of pregnant reached the end of gestation.
