常规超声联合超声造影在诊断产后胎盘滞留中的应用观察

Observation on Application of Conventional Ultrasound Combined with Contrast-enhanced Ultrasound in the Diagnosis of Postpartum Placental Retention

目的:探究常规超声联合超声造影在诊断产后胎盘滞留中的应用价值。方法:回顾性分析经临床综合诊断或手术病理诊断确诊的65例产后胎盘残留患者产后临床资料及影像学资料,分析常规超声、超声造影及二者联合诊断产后胎盘滞留的诊断价值。结果:65例产后胎盘滞留患者进行超声造影分为同步或低增强型、快速高增强型、无增强型三种超声造影增强模式,65例患者病理诊断胎盘植入38例,胎盘粘连15例,胎盘残留12例,常规超声与病理诊断一致44例,超声造影与病理诊断结果一致57例,常规超声联合超声造影诊断与病理诊断结果一致61例,常规超声诊断、超声造影及二者联合诊断胎盘植入、胎盘粘连、胎盘残留准确率对应为65.79%和84.21%和92.11%、66.67%和86.67%和93.33%、66.67%和100.00%和100.00%,诊断产后胎盘滞留的准确率对应为66.15%和87.69%和93.85%。结论:常规超声联合超声造影在诊断产后胎盘滞留中较单一检查具有更高的诊断效能,能够提供更多的影像学资料,为患者治疗提供依据。

Objective:To explore the application value of conventional ultrasound combined with contrast-enhanced ultrasound in the diagnosis of postpartum placental retention.Methods:A retrospective analysis was performed on postpartum clinical data and imaging data of 65 patients with postpartum placental retention confirmed by clinical comprehensive diagnosis or surgical pathological diagnosis,and the diagnostic value of conventional ultrasound,contrast-enhanced ultrasound and the combination of the two was analyzed in the diagnosis of postpartum placental retention.Results:65 patients with postpartum placental retention underwent contrast-enhanced ultrasound which were divided into three contrast-enhanced ultrasound enhancement modes of synchronous or low-enhanced mode,fast high-enhanced mode and non-enhanced mode.65 patients with pathological diagnosis showed 38 cases of placental implantation,15 cases of placental adhesion and 12 cases of placental residual,and 44 cases were consistent with conventional ultrasound and pathological diagnosis,and 57 cases were consistent with contrast-enhanced ultrasound and pathological diagnosis,and 61 cases were consistent with conventional ultrasound combined with contrast-enhanced ultrasound diagnosis and pathological diagnosis,and the accuracy rates of conventional ultrasound diagnosis,contrast-enhanced ultrasound and the combined diagnosis of placental implantation,placenta adhesion,placental adhesion and placental residual were 65.79%and 84.21%and 92.11%,66.67%and 86.67%and 93.33%,and 66.67%and 100.00%and 100.00%respectively,and the accuracy rates of diagnosis of postpartum placental retention were 66.15%and 87.69%and 93.85%.Conclusion:Conventional ultrasound combined with contrast-enhanced ultrasound has high diagnostic efficacy than single examination in the diagnosis of postpartum placental retention,and it can provide more imaging data and provide a basis for patient treatment.
