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)可作为临床辅助诊断及监测恶性滋养细胞肿瘤病情变化的重要手段
Objective: This article dynamically observed 26 cases of malignant trophoblastic tumor color Doppler flow imaging performance, aims to study the color Doppler flow imaging in the diagnosis and treatment of malignant trophoblastic tumor value. Results: Abundant color blood flow signals were observed inside and around the tumor area. After Doppler sampling, abnormal blood flow signals were observed. The resistance index (RI <0.5) was significantly lower than that of the uterine artery. Uterine artery in untreated patients had significantly higher maximum systolic velocity (PS) and minimum end-diastolic velocity (ED) and RI than those in clinically recovered group, both of which were statistically different. Therefore, the uterine artery hemodynamics Changes in learning and patient’s condition are closely related, color Doppler flow imaging (CDFI) can be used as clinical assistant diagnosis and monitoring of malignant trophoblastic tumor changes an important means
