腔内探头经腹探查诊断剖宫产瘢痕妊娠的应用价值

Value and Application of Intracavitary Probe Transabdominal Ultrasound in Diagnosis of Cesarean Scar Pregnancy

目的探讨腔内探头经腹探查诊断子宫瘢痕妊娠的临床应用价值。方法收集我院已确诊的剖宫产瘢痕妊娠患者46例,行经腹、经阴道超声及腔内探头经腹3种不同超声检查方式进行对比分析。结果常规经阴道超声及腔内探头经腹超声与常规经腹超声检查确诊率比较有统计学意义(P<0.05);用常规经阴道及腔内探头经腹超声探查子宫瘢痕处肌层厚度比用常规经腹超声图像更加清晰,用腔内探头经腹超声探查瘢痕处滋养层血流阻力指数比较常规经腹及经阴道超声更加敏感。结论腔内探头经腹超声是对常规经腹及经阴道超声的重要补充,对临床的诊断及治疗有重要指导价值。

Objective To evaluate the clinical effectiveness of ITAS（Intracavitary Probe Transabdominal Ultrasound） in diagnosis of CSP（Cesarean Scar Pregnancy）. Methods Conventional TAS（Transabdominal Ultrasound）, conventional TVS（Transvaginal Ultrasound） and ITAS were performed respectively in 46 patients who were confirmed as sufferers from cesarean scar pregnancy in our hospital, based on which comparative analysis was made. Results Comparisons of the definite diagnosis rate were drawn among TAS, TVS and ITAS, which was of great statistical signifieanee（P〈0.05）. Ultrasound images obtained through conventional TVS and ITAS were sharper than that through conventional TAS in displaying the thickness of the muscular layer in the uterine scar. As for exploration of blood flow RI（Resistance Index） in the trophoblast of the scar, ITAS was more sensitive than TAS and TVS. Conclusion As a supplemental diagnostic technique to conventional TAS and conventional TVS, ITAS is of great value in guiding the clinical diagnosis and treatment of CSP.
