本文报道应用彩色多普勒超声系统动态观察１３９例子宫动脉的血流动力学变化。其中７９例为经超声诊断、手术病理证实的子宫肿瘤，另６０例为正常子宫动脉的血流测值。结果：１３９例子宫动脉的彩色多普勒血流显像（ＣＤＦＩ）清晰、色彩明亮、鲜艳、脉冲多普勒（ＰＷ）收缩期呈单峰频谱，上升较快、下降较慢，舒张期有持续血流信号。正常子宫动脉血流量为１９０．９０±８５．７６ｍｌ／ｍｉｎ；良性病变子宫肌瘤值为３７６．４３±９２．３６ｍｌ／ｍｉｎ；恶性病变中以绒毛膜上皮癌值最高，为１４８０．２１±１８０．６２ｍｌ／ｍｉｎ，此值明显高于正常及良性肿瘤。因此，ＣＤＦＩ和ＰＷ可对子宫肿瘤的良、恶性，为临床提供一定的科学依据。
This article reports the use of color Doppler ultrasound system dynamic observation of 139 cases of uterine artery hemodynamic changes. Among them, 79 cases were diagnosed as uterine tumors by ultrasound and the other 60 cases were normal uterine artery. Results: The color Doppler flow imaging (CDFI) of 139 cases of uterine arteries was clear, bright and bright. The pulse wave Doppler (PW) showed a single peak spectrum during systole, rising rapidly, decreasing slowly, and diastolic Continuous blood flow signal. Normal uterine artery blood flow was 190.90 ± 85.76ml / min; benign lesion uterine fibroids value was 376.43 ± 92.36ml / min; malignant lesions in the highest value of choriocarcinoma, 1480.21 ± 180 .62ml / min, this value was significantly higher than normal and benign tumors. Therefore, CDFI and PW can uterine tumor of benign and malignant, provide a scientific basis for clinical.
