【摘要】：目的探讨胎盘植入相关超声图像特征在产前诊断中的价值。方法以70例在我院行产前超声检查疑似胎盘植入并在我院生产的孕妇为研究对象,回顾性分析患者病例、超声报告及图像。确诊以生产中所见及病理结果为准。结果在胎盘植入的产前诊断中,各图像特征(胎盘后方间隙消失、胎盘内广泛腔隙、胎盘内局灶腔隙、胎盘后方血流丰富、子宫膀胱壁界面毛糙)的灵敏度(特异度)分别为71.2%(18.2%)、35.6%(100%)、33.9%(36.4%)、42.4%(81.8%)、18.6%(90.9%)。在对产后子宫切除的预测中,各图像特征的灵敏度(特异度)分别为63.2%(23.5%)、63.2%(82.4%)、21.1%(54.9%)、68.4%(72.5%)、36.8%(90.2%)。结论胎盘植入各图像特征中,胎盘后方间隙消失灵敏度高而特异度低,容易造成误诊,而胎盘内广泛腔隙特异度高,且对预测产后子宫切除灵敏度高,在胎盘植入的产前诊断中具有重要价值。
[Abstract]:Objective to evaluate the value of placental accreta associated ultrasound imaging in prenatal diagnosis. Methods 70 pregnant women with suspected placenta accreta who were examined by prenatal ultrasound in our hospital were studied. The cases, ultrasonic reports and images were analyzed retrospectively. The diagnosis is based on the clinical and pathological findings. Results in the prenatal diagnosis of placenta accreta, the sensitivity (specificity) of all the imaging features (disappearance of posterior placenta space, extensive space in placenta, focal space in placenta, abundant blood flow behind placenta, rough interface of uterine bladder wall) were 71.2, 36.44.41.81.81.81.81.80.The sensitivity (specificity) was 90.9. In the prediction of postpartum hysterectomy, the sensitivity (specificity) of each image feature was 63.2 and 63.2, respectively. There were 54.9and 68.4and 54.9and 68.4and 90.2respectively. Conclusion among the features of placenta accreta, the disappearance of the posterior placenta space is sensitive and the specificity is low, it is easy to cause misdiagnosis, while the wide space in the placenta is highly specific, and it is highly sensitive to predict postpartum hysterectomy. It has important value in prenatal diagnosis of placenta accreta.
