经阴道彩色多普勒超声检查在剖宫产切口瘢痕妊娠诊断中的应用价值

Clinical value of transvaginal doppler color ultrasound in diagnosis of cesarean sear pregnancy

目的探讨经阴道彩色多普勒超声检查在剖宫产切口瘢痕妊娠诊断中的临床应用价值。方法回顾性分析本院术后确诊的41例瘢痕妊娠患者（观察组）及35例剖宫产术后正常妊娠患者（对照组）的临床资料及声像图特点。对比两组剖宫产切口处肌层厚度及妊娠囊下缘与宫颈内口的距离。结果观察组与对照组平均肌层厚度分别为（2．47±0．92）mm、（4．50±1．19）mm，差异有统计学意义（P=0．000）：观察组与对照组妊娠囊下缘与宫颈内口的距离分别为（6．09±1．45）mm、（16．3±3．93）mm，差异有统计学意义（P=0．000）。结论剖宫产切口处肌层厚度以及妊娠囊下缘与宫颈内口的距离是诊断剖宫产切口瘢痕妊娠的敏感指标。

Objective To investigate the clinical value of transvaginal doppler color ultrasound in the diagnosis of cesarean scar pregnancy （CSP）. Methods The ultrasonograhic features and clinical data of 41 patients diagnosed with CSP at our hospital （an observation group） and 35 women normally pregnant after cesarean section （a control group） were retrospectively analyzed. The residual muscular thickness and the distance between gestation sac and intracervical mouth were compared between these two groups. Results The average muscle layer thickness was （2.47±0.92） mm in the observation group and （4.50±1.19） mm in the control group, with a statistical difference （P=0.000）; The distance between gestation sac and intracervical mouth was （6.09±1.45） mm in the observation group and （16.3±3.93） mm in the control group, with a statistical difference （P=-0.000）. Conclusion Residual muscular thickness and the distance between gestation sac and intracervical mouth are sensitive indicators in the diagnosis of CSP.
