目的：通过对子宫肌瘤血液动力学的研究，以探讨其在子宫肿瘤鉴别诊断中的意义。方法：用彩超经腹对53例子宫肌瘤及40例正常人的子宫动脉、肌瘤内及周边血流作检测。结果：（1）肌瘤患者子宫动脉阻力指数（RI）明显低于正常人（P＜0．01）；（2）肌瘤周边动脉RI低于其子宫动脉，而肌瘤内RI低于周边动脉，其差异具有显著意义（P＜0．05）。结论：肌瘤病灶内的血流分布特征与肌瘤的大小、数目及有无变性等密切相关。
Objective: To study the hemodynamic study of uterine fibroids to explore its significance in the differential diagnosis of uterine tumors. Methods: Fifty-three uterine fibroids and 40 normal human uterine fibroids were detected by color Doppler ultrasonography in the uterine artery, myoma and peripheral blood. Results: (1) The uterine artery resistance index (RI) of fibroid patients was significantly lower than that of normal people (P <0.01); (2) RI of myoma was lower than that of uterine artery Artery, the difference was significant (P <0.05). CONCLUSION: The distribution of blood flow in fibroids is closely related to the size, number and presence or absence of fibroids.
