Angle of progression measured using transperineal ultrasound for prediction of uncomplicated operative vaginal delivery : systematic review and meta‐analysis
ABSTRACT Objective To determine whether intrapartum transperineal ultrasound measurement of the angle of progression (AoP) during the second stage of labor can predict uncomplicated operative vaginal delivery (OVD) using vacuum or forceps extraction. Methods A systematic search in PubMed, EMBASE, Scopus, Web of Science and Google Scholar was performed from inception to February 2021. Studies assessing the predictive accuracy of AoP, measured using intrapartum transperineal ultrasound, for uncomplicated OVD, defined as successful vaginal delivery within three pulls using forceps or no more than two detachments of the vacuum extractor cup, were included. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies‐2 (QUADAS‐2) tool. Summary receiver‐operating‐characteristics (ROC) curves, pooled sensitivity and specificity, area under the ROC curve (AUC) and summary likelihood ratios (LRs) were calculated. Results Seven studies reporting on a total of 782 patients undergoing OVD were included in this systematic review and meta‐analysis. Second‐stage AoP measured during maternal rest had a pooled sensitivity of 80% (95% CI, 59–92%) and specificity of 89% (95% CI, 76–95%), with a LR+ of 7.3 (95% CI, 3.1–15.8) for uncomplicated OVD. AoP measured during active pushing had a sensitivity of 91% (95% CI, 85–94%) and specificity of 83% (95% CI, 69–92%), with a LR+ of 5.4 (95% CI, 2.7–10.6) for uncomplicated OVD. The performance of AoP measured at rest was particularly high in nulliparous women, with a sensitivity of 87% (95% CI, 75–94%) and specificity of 90% (95% CI, 82–94%) for uncomplicated OVD. Conclusion AoP may be a reliable predictor for uncomplicated OVD when measured during the second stage of labor, especially in nulliparous women. © 2022 International Society of Ultrasound in Obstetrics and Gynecology..
