SUCCESS RATE OF CERVICAL CERCLAGE IN PREVENTING PRETERM LABOUR
Background: Cervical cerclage has been reported to improve cervical length and restore cervical anatomic relationships. Cerclage placement closer to internal os may be associated with improved perinatal outcome. This study was designed to determine the success rate of cervical cerclage in preventing preterm deliveries in patients having cervical incompetence. Methods: Seventy-five subjects were selected by consecutive (non-probability) sampling technique. All patients were having a history of two or more recurrent mid trimester abortions or preterm deliveries and were subjected to cervical cerclage. Age, gravidity, and parity of the patients, and gestational age at delivery, weight of the baby and Apgar score was recorded. Success rate of cervical cerclage was calculated. Results: The mean age of the patients was 28.35Â±3.96 year, gestation number was 5.33Â±2.36, and parity was 1.7Â±1.46. Most (65.3%) of the cases delivered at term (>37 weeks), 17.3% had preterm deliveries (28â€“37 weeks) and 17.3% had abortions (12â€“28 weeks). Sixty-four percent of babies had birth weight â‰¥2.5 Kg, and 36.0% had birth weight <2.5 Kg. Foetal survival rate (good Apgar score) was 76%. Overall success rate of cervical cerclage was 80%. Conclusion: Application of cervical cerclage in pregnant women with previous preterm delivery reduces the preterm delivery rate at a reasonable cost with no additional risk to the mother and the foetus.
