Resultados gestacionais e perinatais de gesta？？es com insuficiência cervical submetidas a circlagem eletiva

purpose: to describe the pregnancy outcome of women submitted to cervical cerclage during pregnancy. methods: a series of 123 pregnancies in 116 women submitted to elective cervical cerclage by espinosa-bahamondes, palmer and macdonald techniques and followed at the high-risk antenatal care unit at caism/unicamp is described. variables were analyzed through frequency, mean and standard deviation, comparisons were made using c2 or fisher exact tests. results: 73% had at least one previous abortion, 17.9% had had 3 prior abortions, and 48% had prior preterm deliveries. the mean gestational age at cerclage was 16 weeks. cerclage by the espinosa-bahamondes technique predominated (94.3%). the overall complication rate was 69%, with preterm labor as the most frequent (31.7%), followed by vaginitis (26%), preterm premature rupture of membranes (10.5%) and fetal death (8.7%). other clinical complications were less common and included urinary tract infections (5.6%), hypertensive disorders (4%) and gestational diabetes (2.4%). fetal loss occurred in 8.9% of pregnancies (11 stillbirths). premature deliveries were present in 18%. history of previous premature deliveries was associated with the occurrence of premature deliveries. conclusion: obstetrical history compatible with cervical incompetence was frequent, and prior preterm delivery was associated with a preterm delivery in the pregnancy under analysis. the use of cerclage by the espinosa-bahamondes technique resulted in 18% of premature newborns, and 104 per thousand rate of perinatal death. prospective, controlled trials are needed to evaluate the real benefits of cervical cerclage performed during pregnancy.
