Rescue Cervical Cerclage for Previable Birth Prevention: A Comprehensive Review of Indications, Techniques, and Outcomes.

Cervical cerclage is a surgical intervention aimed at preventing previable birth by providing mechanical support to the cervix through the placement of a suture. This procedure is primarily indicated for cases of cervical incompetence, where the cervix is prone to premature dilation and can lead to early miscarriage or preterm birth. This review seeks to comprehensively analyze rescue cervical cerclage (RCC), focusing on its indications, techniques, and outcomes. The goal is to offer an in-depth understanding of its effectiveness in preventing previable birth and to guide clinical decision-making in managing pregnancies at risk of premature delivery. A thorough literature review examined recent studies and clinical data on RCC. Key aspects evaluated include the criteria for intervention, various surgical techniques employed, and the associated maternal and fetal outcomes. Comparative analysis was also performed with other preventive measures, such as progesterone therapy and bed rest. RCC has demonstrated efficacy in reducing the incidence of previable births, particularly when performed in cases of identified cervical incompetence or shortening. The review highlights variations in the technique, such as McDonald and Shirodkar cerclage, and discusses their relative success rates and potential complications. The procedure is associated with improved pregnancy outcomes and reduced risk of previable birth, though it carries some risks, including infection and cervical laceration. RCC remains a valuable intervention for preventing previable births in selected patients. This review underscores its importance in managing pregnancies at risk due to cervical incompetence and provides a detailed evaluation of its indications, techniques, and outcomes. Future research should optimize criteria for cerclage placement and explore novel strategies to enhance its effectiveness and safety.
