Cervical Length in Patients With Placenta Accreta Spectrum and Its Association With Unscheduled Delivery.
Objectives: To evaluate the association between cervical length (CL) and unscheduled delivery in patients with placenta accreta spectrum (PAS).
Methods: Retrospective cohort study of patients with suspected PAS from January 2018 to June 2024. Patients with suspected PAS underwent serial ultrasounds including transvaginal CL measurement every 4 weeks. The final CL measurement prior to delivery was analyzed. Unscheduled delivery was defined as urgent delivery prior to the scheduled date due to either bleeding or preterm contractions. A receiver operating characteristics (ROC) curve was created, the optimal CL associated with unscheduled delivery was selected, and associations and prediction analyses were performed.
Results: Of 102 patients, 21 (20.6%) had an unscheduled delivery. Median gestational age at unscheduled delivery was 30w5d (IQR 29w0d-34w1d), and at scheduled delivery 34w0d (IQR 33w1d-34w4d, P = 0.001). CL was shorter in patients who had an unscheduled delivery compared to those with a scheduled delivery (mean [SD] 29.9 [10.2] mm versus 36.1 [10.3] mm, P = .02). CL was shorter (31.6 [SD 11.1] mm) among patients (n = 53) having a delivery <34w0d than those (n = 49) delivering ≥34.0w0d (38.5 [SD 8.6] mm, P < .001). ROC analysis showed a CL of 30 mm as the optimal cutoff for prediction of unscheduled delivery. A significant association between CL ≤30 mm with unscheduled delivery (adjusted relative risk [aRR] 2.33, 95% CI: 1.08-5.03, P = .03) was observed after adjusting for history of spontaneous preterm birth.
Conclusions: In patients with PAS, a CL ≤30 mm is associated with a higher rate of unscheduled delivery and delivery ≤34 weeks.
