Abstract:

Perinatal complications and comorbidities are significantly more common in triplets pregnancies than in single and twin pregnancies, the most significant of which are preterm and preterm birth morbidity and mortality. The risk of miscarriage or preterm birth increases if triplet pregnancies are combined with cervical incompetence. The paper reports two cases of dichorionic triamniotic triplet pregnancies conceived by assisted reproductive technology complicated with cervical incompetence. One case underwent preconception laparoscopic cervical cerclage, and the other underwent transvaginal cervical cerclage at 15⁺⁵ weeks of gestation. Regular vaginal ultrasound monitoring of cervical length and timely treatment to prevent premature birth were peformed during pregnancy. Three live babies were delivered by cesarean section at 33⁺² weeks and 33⁺³ weeks respectively. Cervical cerclage is a reliable treatment option, especially for those opting against fetal reduction. Regular follow-up is very important for preventing premature birth, guiding clinical medication, timely removal of cervical cerclage and improving the prognosis of mother and child.
