应用彩色多普勒血流显像(CDFI)对34例恶性滋养细胞肿瘤的声像表现进行分析研究,旨在探讨CDFI在恶性滋养细胞肿瘤诊断、判断化疗效果,预测病变转归等方面的临床价值.结果发现恶性组子宫动脉血流参数与良性组、早孕组、非孕组对比均有显著性差异(P<0.01),恶性组子宫肌壁血流丰富,肿瘤区显示大小不等的血窦,呈低阻特性,以RI<0.46作为诊断恶性肿瘤的界定指标具有可行性.应用CDFI动态观察化疗患者,这对预测疾病转归有实际应用意义.
Color Doppler flow imaging (CDFI) in 34 cases of malignant trophoblastic tumors were analyzed to explore the CDFI in the diagnosis of malignant trophoblastic tumor, to determine the effect of chemotherapy, predictive prognosis and other aspects of the clinical The results showed that there were significant differences between uterine arterial blood flow parameters in malignant group and those in benign group, early pregnancy group and non-pregnant group (P <0.01), the uterine wall blood flow was rich in malignant group, Sinus, showed low resistance, RI <0.46 as a definitive indicator of malignancy feasibility.Using CDFI dynamic observation of patients with chemotherapy, which predict the prognosis of the disease has practical significance.
