目的 探讨CT及超声在剖宫产瘢 痕部位妊娠中的诊治价值。方法 选择56 例剖宫产瘢痕部位妊娠(CSP)患者，回顾 性分析CT及超声影像学资料，总结其影像 学分型及治疗方式的选择，评定CT、超 声在剖宫产瘢痕妊娠中的诊断价值。结 果 56例CSP中，单纯孕囊型40例，植入型 16例。超声诊断符合率为91.07%，CT诊断 符合率为87.50%，两者联合诊断准确率为 98.21%；单用超声诊断准确率与CT对比差 异无统计学意义(P>0.05)。结论 超声、 CT检查为CSP诊断的有效方式，CT对孕囊 植入及血供判断优势明显，可为术前评估 及手术方式的制定奠定影像学基础。

Objective To explore the diagnostic and therapeutic value of CT and ultrasound in cesarean scar pregnancy (CSP). Methods 56 patients with CSP were included in the study. The CT and ultrasound imaging data were retrospective analyzed. The imaging type and and selection of treatment were summarized. The diagnostic value of CT and ultrasound in CSP was evaluated. Results Among the 56 cases with CSP, 40 cases were simple gestational sac type and 16 cases were implantation type. The coincidence rate of ultrasound diagnosis was 91.07% while of CT diagnosis was 87.50%. The accuracy of combined diagnosis was 98.21%; There was no significant difference in accuracy of ultrasound diagnosis alone and CT (P>0.05). Conclusion Ultrasound and CT examination are the effective ways for the diagnosis of CSP. CT has more advantages in diagnosis of gestational sac implantation and blood supply, which can lay imaging foundation for preoperative evaluation and selection of surgical method.
