Arabin Pessary -Assuring to Solve the Misery: A Case Series

Abstract

Background: Preterm birth remains a leading cause of perinatal morbidity and mortality. Cervical insufficiency contributes significantly, and its treatment strategies remain debated. The Arabin pessary, a non-invasive device, is emerging as a potential adjunct to cerclage. Methods: We retrospectively reviewed three singleton pregnancies at Sri Ramachandra Hospital, Chennai, who underwent combined cerclage and Arabin pessary placement due to persistent cervical shortening (<25 mm) after cerclage. Outcomes were compared with evidence from existing literature. Results: All three patients delivered at term without major complications. One patient had vaginal discharge, which resolved with conservative management. Neonatal outcomes were favorable. Conclusion: Arabin pessary may provide additional mechanical support in selected women with cervical shortening despite cerclage. While our series suggests safety and potential benefit, larger randomized controlled trials are required to define its role.
