- Abstract
Objective: To investigate the value of ultrasound parameters in assessing the efficacy of transabdominal ultrasound (TAUS)‐guided suction curettage alone for cesarean scar pregnancy (CSP). Methods: Secondary retrospective analysis of a prospective study consisted of 137 women diagnosed with CSP who were performed TAUS‐guided suction curettage alone for the first time at Maternity and Child Health Care of Guangxi Zhuang Autonomous Region in China. Prior to surgery, an ultrasound examination was conducted. Based on the need for secondary intervention, the patients were categorized into failure group and success group, and the predictive factors for failure of TAUS‐guided suction curettage alone were analyzed. Results: Multivariate logistic regression showed that maximum diameter of the gestational sac>29 mm (odds ratio [OR] = 4.043, 95% CI: 1.100–14.862), residual myometrium thickness ≤1.8 mm (OR = 3.719, 95% CI: 1.148–12.048) and chorionic villi thickness at the scar >4.7 mm (OR = 15.327, 95% CI: 4.617–50.881) were independent predictors of failure in TAUS‐guided suction curettage alone for CSP. Furthermore, the logistic regression model that was jointly constructed by these three predictors demonstrated an area under the curve, sensitivity, specificity, and Youden index of 0.913, 0.912, 0.864, and 0.776, respectively. Conclusion: The maximum diameter of the gestational sac, residual myometrium thickness, and chorionic villi thickness at the scar has certain predictive efficacy of TAUS‐guided suction curettage alone for CSP. Nevertheless, it is more valuable to apply the model of this study, composed of the three ultrasound parameters, for this prediction purpose.
