目的 探讨经阴道彩色多普勒 (CDFI)及脉冲多普勒 (PD)超声对绒毛膜癌的诊断 ,疗效观察及判断疾病转归的应用价值。方法 对 1 4例绒毛膜癌患者进行经阴道彩色多普勒及脉冲多普勒 (PD)超声检查 ,并记录病灶及子宫动脉血流阻力指数 ,同时记录血清绒毛膜促性腺激素 (β- HCG)值。结果 1 4例绒毛膜癌患者中 ,2例为附件区包块型 ,2例为阴道壁包块型 ,1例为子宫颈包块型 ,9例为子宫肌壁肿瘤型 ,不同类型的二维声像图特征不同 ,超声图像、病灶及子宫动脉血流阻力指数、血清绒毛膜促性腺激素值三者呈正相关关系。结论 经阴道彩色多普勒超声显示病灶异常血流图像和脉冲多普勒 (PD)检测病灶及子宫动脉低 RI值是诊断绒毛膜癌的重要指标 ,对监测化疗效果、选择治疗方案均有十分重要的价值
Objective To investigate the diagnosis and curative effect of choriocarcinoma by transvaginal color Doppler (CDFI) and pulsed Doppler (PD) ultrasonography and to evaluate the value of prognosis of choriocarcinoma. Methods Totally 14 cases of choriocarcinoma were examined by transvaginal color Doppler and pulsed Doppler (PD) ultrasonography. The indexes of blood flow resistance of lesions and uterine artery were recorded. Meanwhile, the serum levels of chorionic gonadotropin (β-HCG )value. Results Among the 14 cases of choriocarcinoma, 2 were in the annexing area, 2 were vaginal wall mass, 1 was cervical mass, 9 were uterine muscular wall tumor type, and 2 There were positive correlations between the features of the three dimensions of the ultrasonography, lesion, uterine artery blood flow resistance index and serum chorionic gonadotropin. Conclusion Transvaginal color Doppler ultrasound imaging of abnormal blood flow and pulse Doppler (PD) detection of lesions and uterine artery low RI value is an important indicator of diagnosis of choriocarcinoma, the monitoring of chemotherapy, the choice of treatment are very Important value
