摘要
目的 :本文动态观察 2 6例恶性滋养细胞肿瘤的彩色多普勒血流显像的表现 ,旨在研究彩色多普勒血流显像在恶性滋养细胞肿瘤诊断和治疗中的应用价值。结果 :患者肿瘤区内部及周边可见丰富的彩色血流信号 ,经多普勒取样后 ,可见异常血流信号 ,其阻力指数 (RI <0 .5 )明显低于子宫动脉。未经治疗患者的子宫动脉与临床已痊愈组相比 ,其最大收缩期速度 (PS)与最小舒张末期速度 (ED)明显增高而RI明显降低 ,均具有统计学差异 ,故子宫动脉的血液动力学变化与患者的病情变化密切相关 ,彩色多普勒血流显像 (CDFI)
Objective: To evaluate the application of color Doppler flow imaging (CDFI) in determination of the arterial blood flow of malignant trophoblastic tumor. Methods: Twenty six patients with malignant trophoblastic tumor (MTT) underwent color Doppler flow imaging examination. Results: There were signals of abundant color blood flow within or around MTT and abnormal blood flow signals were demonstrated on vascular territories by the pulsed Doppler. The RI of tumor vessels is much lower than that of normal uterine artery. Compared to clinically cured patients, the PS and ED of the uterine artery blood flow in untreated patients were much higher and RI much lower. Conclusions: There is a strong correlation between the hemodynamics of uterine artery and curative effects. Moreover, CDFI may be an important alternative method of choice in diagnosis and follow-up of MTT.
