| 摘 要： | 目的探讨经阴道彩色多普勒超声（CDFI）在恶性滋养细胞肿瘤的诊断及化疗监测中的应用价值。方法本文对36例恶性滋养细胞肿瘤患者、36例早孕及20例良性葡萄胎对照组采用经阴道彩色多普勒超声（CDFI）进行检测，对其子宫肌壁内血流信号、子宫动脉频谱、动静脉频谱等CDFI特征进行对比分析。记录病灶区及子宫动脉血流阻力指数（RI），并记录血绒毛膜促性腺激素（β-HCG）值。对36例恶性滋养细胞肿瘤化疗前后CDFI特征进行对比分析。结果恶性滋养细胞肿瘤子宫动脉RI值较低，为高速低阻力性动脉频谱；恶性滋养细胞肿瘤宫壁血流异常丰富，子宫肌层病灶内血管阻力指数RI〈0．4；恶性滋养细胞肿瘤患者全身化疗取得疗效后子宫肌层血流丰富区逐渐缩小，RI呈逐渐升高趋势，血β-HCG逐渐恢复正常。结论经阴道彩色多普勒超声有助于恶性滋养细胞肿瘤的早期诊断，对评价化疗效果、指导治疗、判断预后有重要参考价值。
