目的探讨高频超声在评价晚孕子宫瘢痕愈合中的价值。方法对65例晚孕子宫瘢痕,经腹低频、高频超声分别检查后,测量瘢痕厚度并观察回声的变化,其结果与手术诊断相对照。结果手术诊断为子宫切口愈合良好孕妇中。超声低频诊断符合率为74.4%,高频诊断符合率为97.4%,差异有统计学意义(P<0.05)。手术诊断为子宫瘢痕缺陷孕妇中,超声低频诊断符合率为69.2%,高频诊断符合率为92.3%,差异有统计学意义(P<0.05)。结论经腹高频超声检查安全、简便,能更客观地反映子宫瘢痕的愈合情况,使诊断准确率明显提高,是诊断子宫瘢痕愈合情况的首选方法,值得推广应用。
Objective To investigate the value of high frequency ultrasound in evaluating uterine scar healing in late pregnancy. Methods 65 cases of late pregnancy uterine scar, abdomen low frequency, high frequency ultrasound were examined, the scar thickness was measured and observed changes in echo, the results of surgery and surgery in contrast. Results The surgical diagnosis of uterine incision healed well in pregnant women. The coincidence rate of ultrasonic low frequency diagnosis was 74.4%, high frequency diagnosis coincidence rate was 97.4%, the difference was statistically significant (P <0.05). Among the pregnant women diagnosed as uterine scar defect, the coincidence rate of ultrasonic low frequency diagnosis was 69.2% and high frequency diagnosis rate was 92.3%, the difference was statistically significant (P <0.05). Conclusion Abdominal ultrasonography is safe and simple, and can reflect the healing of uterine scar more objectively. The accuracy of diagnosis is significantly improved. It is the first choice to diagnose the healing of uterine scar, which is worth popularizing and applying.
