Perioperative complications of history-indicated and ultrasound-indicated cervical cerclage.

Abstract

To evaluate perioperative complications of history- and ultrasound-indicated cerclage. We performed a retrospective observational study of a cohort of patients who underwent history- (n = 198) or ultrasound-indicated (n = 89) cerclage procedures. We evaluated the rates of perioperative complications based on indication for cerclage. The χ(2) was used for categorical variables and Student t test for continuous data. One patient (0.35%) had an intraoperative complication (unsuccessful regional anesthesia) and 1 patient (0.35%) had a postoperative complication (contractions and bleeding 2 weeks after cerclage placement, delivered a nonviable infant). Peripartum complications included chorioamnionitis (6.2%), preterm premature rupture of membranes (11%), preterm delivery (20%), and delivery before 32 weeks' gestational age (8%), and they were similar in the history-indicated and ultrasound-indicated groups. History- and ultrasound-indicated cerclages are associated with a 0.6%; 95% confidence interval, -0.26 to 1.66 risk of perioperative complications. There was no difference in perioperative complications or outcome between the 2 groups.
