Patients with suspected PAS underwent serial ultrasounds including transvaginal CL measurement every 4\u2009weeks. 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 102 patients, 21 (20.6%) had an unscheduled delivery.

CL was shorter (31.6 [SD 11.1] mm) among patients (n\u2009=\u200953) having a delivery &lt;34w0d than those (n\u2009=\u200949) delivering \u226534.0w0d (38.5 [SD 8.6] mm, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001).
