Cerclage Placement in Patients with Amniotic Fluid Sludge

Clinical Implications and Management Recommendations

  • The Society for Maternal-Fetal Medicine (SMFM) notes that cerclage management after preterm premature rupture of membranes (PPROM) is controversial with limited evidence 1, 2
  • Cerclage retention after PPROM does not significantly prolong pregnancy compared to removal (45.8% vs 56.2% had 1-week prolongation) 1, 2
  • No significant differences in rates of chorioamnionitis (41.6% vs 25.0%), postpartum endometritis (12.5% vs 3.1%), or neonatal outcomes with cerclage retention vs removal 1, 2
