Abstract

Study objective To describe a novel technique of transvaginal cervicoisthmic cerclage with a polypropylene sling in prevention of preterm labor in pregnant women at high risk. Design Retrospective study (Canadian Task Force classification: III). Setting University hospital (department of obstetrics and gynecology). Patients Twenty-one women showing symptoms of high risk of preterm delivery: histories of pregnancy losses in the second trimester and prior failure of MacDonald’s cerclage or absent portio vaginalis of the cervix. The median age of the patients was 32.8 years (range 22–39 years). Interventions Cerclage was performed between 12 and 16 weeks’ gestation. A polypropylene tape was placed at the cervicoisthmic junction by vaginal route. Caesarean delivery was systematically performed in all patients because the cerclage was considered to be definitive. Measurements and main results No intraoperative complications occurred. The mean operating time was 36 ± 6 minutes (range 30–45 minutes). The mean length of stay was 1.4 ± 0.5 days. Mean gestational age and birth weight at delivery were respectively 37.1 ± 1.8 weeks (CI 95%: 36.4–37.9) and 2850 ± 745 g (CI 95%: 2531–3168). The preterm birth rate was 19% (4/21). One neonatal death occurred after amniotic fluid infection at 34 weeks. Birth at less than 32 weeks occurred in one patient (4%). Conclusion Transvaginal cervicoisthmic cerclage with polypropylene sling may be considered as an effective and minimally invasive alternative to the transabdominal cervicoisthmic cerclage in women presenting with high risk of preterm delivery.
