Predictive value of cervical length in placenta previa totalis: a single-center experience

Abstract

Aims: In our study, we aimed to scientifically assess the utility of measuring cervical length in predicting the risk of postpartum hemorrhage and the necessity for emergency preterm cesarean delivery in women diagnosed with placenta previa totalis. Methods: We conducted a retrospective study at a single medical center, comprising 48 pregnant women diagnosed with placenta previa totalis. Cervical length was precisely measured through transvaginal ultrasound. Patients were categorized based on cervical length (CL): CL >30mm, CL 25-30 mm, and CL <25 mm. Primary outcomes included preterm birth, postpartum hemorrhage, and emergency cesarean section. Results: Women with CL <25 mm exhibited a notably elevated risk of postpartum hemorrhage (60%) and emergency cesarean section (80%). While preterm birth rates displayed variations among groups, statistical significance remained elusive. APGAR scores demonstrated consistency across cervical length categories. Conclusion: Evaluation of cervical length holds promise as a valuable tool in the comprehensive management of placenta previa totalis. Women presenting with a cervical length less than 25 mm may warrant intensified monitoring and targeted interventions to mitigate adverse perinatal outcomes. Further research endeavors are imperative to corroborate these findings and advance the care provided for these intricate pregnancies.
