【摘要】 目的探讨产后胎盘滞留的实时灰阶超声造影声像表现及其临床指导意义。方法回顾性分析28例产后胎盘滞留(其中胎盘残留6例,粘连性胎盘6例,植入性胎盘16例)患者的常规超声表现及实时灰阶超声造影增强模式。结果产后胎盘滞留的超声造影增强模式分为快速高增强型、同步等或低增强型和无增强型。常规超声联合超声造影诊断胎盘残留、粘连性胎盘和植入性胎盘的符合率(25/28,89.29%)较常规超声(16/28,57.14%)高,差别有统计学意义(P<0.05)。结论实时灰阶超声造影有助于产后胎盘滞留原因的诊断与分析,为临床制定个性化治疗方案提供影像学依据。更多还原

【Abstract】 Objective To explore the image of contrast-enhanced ultrasound(CEUS) in postpartum placental retention and its clinical significance. Methods We performed a retrospective analysis on 28 cases of postpartum placental retention(6 cases of placenta residue, 6 cases of adherent placenta, 16 cases of placenta increta) patients with conventional ultrasonography findings and contrast-enhanced ultrasound enhanced mode. Results Postpartum retention of placenta ultrasound imaging enhancement pattern was divided into three types: high rapid enhancement, synchronous or low enhanced, and not-enhanced. The coincidence rate of conventional ultrasonic combined CEUS in the diagnosis of placenta residue, placenta adhesion and placenta increta(89.29%,25/28) was significantly higher than conventional ultrasound(57.14%, 16/28)(P<0.05). Conclusion CEUS is helpful in diagnose of postpartum placental retention, for better understanding of its courses, and it may help with providing personalized treatment options with imaging date.更多还原
