Our study sought to obtain data which assess the diagnostic value of transvaginal three-dimensional ultrasound (3D-US) combined with color Doppler ultrasound (US) for early cesarean scar pregnancy (CSP).
All participants were randomly divided into a Control group diagnosed using 3D-US and a Combination group diagnosed using 3D-US combined with color Doppler US. The preoperative US results were compared with postoperative pathological results. The diagnostic coincidence rate, sensitivity, and specificity of these two examination methods were compared, and their diagnostic results for different types of CSP were analyzed. Finally, the diagnostic effects of both methods were compared and analyzed, and the imaging of CSP was summarized.
The diagnostic accuracy of transvaginal 3D-US combined with color Doppler US (92.96%) was significantly higher than that of transvaginal 3D-US (71.83%). For different types of CSP, the diagnostic rate of CSP with mixed echogenic mass and partial implantation of gestational sac in the Combination group was markedly higher than that in the Control group.
Additionally, the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC) in the Combination group were higher than those in the Control group. Transvaginal 3D-US combined with color Doppler US can improve the sensitivity, specificity, and accuracy of diagnosis of early CSP, and has important reference value for clinical condition evaluation and treatment options.
本研究旨在获取数据，评估经阴道三维超声（3D-US）联合彩色多普勒超声（US）对早期剖宫产瘢痕妊娠（CSP）的诊断价值。
所有参与者均随机分为经 3D-US 诊断的对照组和经 3D-US 联合彩色多普勒 US 诊断的联合组。将术前 US 结果与术后病理结果进行比较。比较两种检查方法的诊断符合率、灵敏度和特异度，并分析其对不同类型 CSP 的诊断结果。最后比较分析两种方法的诊断效果，总结 CSP 的影像学特征。
经阴道 3D-US 联合彩色多普勒 US 的诊断准确率（92.96%）明显高于经阴道 3D-US（71.83%）。对于不同类型的 CSP，联合组中混合回声团块和部分孕囊着床的 CSP 诊断率明显高于对照组。
此外，联合组的敏感性、特异性和受试者工作特征（ROC）曲线下面积（AUC）均高于对照组。经阴道 3D-US 联合彩色多普勒 US 可提高早期 CSP 的诊断灵敏度、特异性和准确性，对临床病情评估和治疗方案选择具有重要参考价值。
