目的探讨二维超声联合彩色多普勒超声对于瘢痕子宫合并前置胎盘、胎盘植入患者的诊断效果。方法 40例子宫瘢痕合并前置胎盘的患者,产前进行二维超声及彩色多普勒超声检查,并进行跟踪随访,探查孕妇胎盘、子宫、膀胱超声图像特征,判断有无胎盘植入,金标准为分娩时手术和病理结果。结果 40例入选产妇中,经手术和病理结果确诊有前置胎盘并植入7例,胎盘植入发生率为17.5%(7/40),彩色多普勒诊断瘢痕子宫患者合并前置胎盘植入的敏感性为85.7%(6/7),特异性为97.0%(32/33),假阳性率为3.0%,假阴性率为14.3%。结论运用超声诊断瘢痕子宫合并前置胎盘植入的临床特异性与灵敏度较高,效果较好,值得临床推广。
Objective To investigate the diagnostic value of two-dimensional ultrasonography combined with color Doppler ultrasound in the treatment of patients with scar uterus with placenta previa and placenta accreta. Methods Forty patients with uterine scar and placenta previa were examined with two-dimensional sonography and color Doppler sonography before and after follow-up to explore the characteristics of placenta, uterus and bladder ultrasound images of pregnant women to determine the presence or absence of placenta accreta, gold The standard for childbirth surgery and pathological results. Results Forty cases of selected mothers were diagnosed with placenta previa and pathological findings in 7 cases, the incidence of placenta accreta was 17.5% (7/40), color Doppler diagnosis of uterine scar patients with placenta previa The sensitivities were 85.7% (6/7), 97.0% (32/33), false positive rate 3.0% and false negative rate 14.3%. Conclusion Ultrasound diagnosis of uterus with placenta previa placenta accreta has a higher specificity and sensitivity, the effect is better, worthy of clinical promotion.
