目的:探讨剖宫产后子宫瘢痕妊娠的超声检查方法和图像表现,并就其误诊的原因进行总结。方法:选用本院自2010年3月到2014年9月期间所收治的26例剖宫产后瘢痕子宫早期妊娠患者的确诊超声图像,分析相关的超声诊断方法及出现误诊问题的原因。结果:针对本次所观察的26例病患,首次超声诊断确诊病例为23例,诊断准确率为88.5%。首次单纯经阴道超声检查病例为6例,诊断准确率为83.3%;单纯经腹部超声检查病例为8,其中确诊病患为6例,诊断准确率为75%;经二者联合超声检查的病例为12例,诊断准确率高达100%。结论:在子宫瘢痕妊娠的早期诊断中应用超声检查具有非常重要的价值,并且膀胱充盈程度和超声检查的方法均会对超声诊断的准确性产生影响。
Objective: To investigate the method of ultrasound examination and imaging of uterine scar pregnancy after cesarean section, and to summarize the reasons of misdiagnosis. Methods: The ultrasound images of 26 patients with early uterine cesarean scar after cesarean section were selected from March 2010 to September 2014 in our hospital. The related ultrasonic diagnostic methods and the causes of misdiagnosis were analyzed. Results: For the 26 patients observed in this study, 23 cases were diagnosed by first ultrasonography and the diagnostic accuracy was 88.5%. The first simple transvaginal ultrasonography in 6 cases, the diagnostic accuracy rate was 83.3%; simple transabdominal ultrasound examination of 8 cases, of which 6 cases were diagnosed, the diagnostic accuracy rate of 75%; the two combined ultrasound examination of the cases For 12 cases, the diagnostic accuracy rate of up to 100%. Conclusion: It is very important to apply ultrasound in the early diagnosis of uterine scar pregnancy, and the degree of bladder filling and ultrasound examination will affect the accuracy of ultrasound diagnosis.
