目的:探讨经阴道彩色多普勒超声在恶性滋养细胞肿瘤诊断和治疗中的应用价值。方法:对21例恶性滋养细胞肿瘤的子宫动脉及肿瘤内的血流进行了检测,30例正常早孕组作为对照组。结果:恶性滋养细胞肿瘤的子宫动脉及肿瘤内血管的阻力指数明显低于正常早孕组,化疗前病变区血流异常丰富,呈现低阻性血流,化疗后病变区血流信号明显减少,化疗前后砌值明显有差异(P<0.05);监测化疗效果与血β-HCG相关性好。结论:经阴道彩色多普勒超声在滋养细胞肿瘤良、恶性的判断及化疗效果的监测上是一个很有价值的方法。
Objective: To investigate the value of transvaginal color Doppler ultrasound in the diagnosis and treatment of malignant trophoblastic tumor. Methods: Twenty-one cases of malignant trophoblastic tumor with uterine artery and tumor blood flow were detected, and 30 cases of normal pregnancy group as control group. Results: The resistance index of uterine artery and tumor in malignant trophoblastic tumor was significantly lower than that in normal pregnancy group. The pre-chemotherapy area had abnormally high blood flow and low resistive blood flow. After chemotherapy, the signal of blood flow in the diseased area was significantly reduced. Before and after the puzzle value was significantly different (P <0.05); monitoring of chemotherapy and blood β-HCG correlation is good. Conclusion: Transvaginal color Doppler ultrasonography is a valuable method in judging benign and malignant tumors of trophoblastic tumor and monitoring the effect of chemotherapy.
