Association of adherence to guidelines for cervical cerclage with perinatal outcomes and placental inflammation in women with cervical length ≥2.0 cm.
OBJECTIVES: Cerclage operation is one of the most common obstetric controversies. The aim of this study was to compare the perinatal outcomes and placental inflammation of cerclage performed adherent and non-adherent to international guidelines.
MATERIAL AND METHODS: This study included all consecutive women with singleton deliveries who underwent cerclage. According to the current American College of Obstetricians and Gynecologists (ACOG) guideline, we designated our study population into two groups: the adherent-to-guideline and non-adherent groups. Each group was categorized into two groups according to cervical length (CL) at the time of cerclage (<2.0 cm vs. ≥2.0 cm). We evaluated the reasons for cerclage, maternal characteristics, perioperative variables, pregnancy and neonatal outcomes, and placental inflammatory pathology according to the criteria proposed by the Society of Pediatric Pathology.
RESULTS: Among 310 women with cerclage, we excluded patients (n = 21) with indicated preterm delivery (PTD), major fetal anomaly, fetal death in-utero, and missing information for reason of cerclage. We also excluded patients who underwent physical examination-indicated cerclage (n = 53) and with missing information of CL at the time of cerclage (n = 52). A total of 184 women were eventually analyzed. In women with CL < 2.0 cm, the non-adherent group showed similar PTD (<28 weeks, <34 weeks) and neonatal composite morbidity rates compared to the adherent-to-guideline group. However, in women with CL ≥ 2.0 cm, the non-adherent group manifested significantly higher PTD (<28 weeks; 16.7% vs. 4.4%, p = 0.04, <34 weeks; 23.8% vs. 5.8%, p = 0.006) and neonatal composite morbidity (20.5% vs. 5.9%, p = 0.028) rates than the adherent-to-guideline group despite similar perioperative variables and lower PTD history rates. The non-adherent group with CL ≥ 2 cm at the time of cerclage was also associated with severe histologic chorioamnionitis (p = 0.033).
CONCLUSION: Cerclage performed beyond the current guidelines in pregnant women with CL ≥ 2.0 cm may confer an additional risk of perinatal complications in association with severe placental inflammation.
