RESUMO
A 38-year-old nulliparous woman was referred to our clinic because of cervical incompetence at 19 weeks of gestation. Trans-abdominal cervicoisthmic cerclage was performed after failure of modified Shirodkar cerclage operation in the patient at 21 weeks of gestation via a laparotomic approach. Another 38-year-old patient, who underwent loop electrosurgical excision procedure conization for treatment of cervical dysplasia 4 years ago, presented for cervical incompetence. At 18 weeks of gestation, we performed trans-abdominal laparotomic cervicoisthmic cerclage without any post-operative complications. During antenatal follow-up, there were no obstetrical co-morbidities and finally she gave birth to a healthy infant at full term by cesarean section. We report two cases of women who underwent trans-abdominal cervicoisthmic cerclage surgery because of cervical incompetence as they were not suitable for transvaginal cervical cerclage. Both patients successfully maintained their pregnancy until full term after undergoing transabdominal cervicoisthmic cerclage at more than 18 weeks of gestation.
