摘要
目的 通过对子宫动脉血流动力学的研究 ,探讨彩色多普勒超声在子宫动脉栓塞术治疗子宫肌瘤前后的血流动力学变化。方法 用彩超检测 2 1例子宫肌瘤的子宫动脉、肌瘤内及周边血流。并行双侧子宫动脉栓塞(UAE) ,于栓塞前 1周内和栓塞后 3～ 6d、3～ 6个月做彩色多普勒超声检查。结果 ①该组病例子宫动脉栓塞后 3～6d ,子宫动脉及肌瘤内无血流显示 ,3～ 6个月 ,子宫肌瘤内仍无血流显示 ,部分子宫动脉可探及血流信号 ,其阻力指数 (RI)、血流速度 (Vm)明显降低 (P <0 .0 1) ;②所有病例随访 3～ 64个月 ,瘤体体积缩小 40 %～ 90 %。结论 子宫动脉栓塞术治疗子宫肌瘤早期是有效的 ,其远期效果需进一步观察 。
Objective To study the blood flow characteristic of uterine myoma and to assess the hemodynamic change of uterine artery in hysteromyoma before and after uterine arterial embolization(UAE). Methods The uterine arteries, intratumor arteries and bilateral arteries were explored by color Doppler flow imaging(CDFI) at one week before UAE and 3～6 days, 3～6 months after UAE in 21 cases with hysteromyoma. Results ① The color images of all arteries were disappeared at 3～6 days after UAE, and part uterine arteries could be detected by CDFI at 3～6 months after UAE, but the RI and Vmax decreased markedly(P<0.01).② The size of tumor reduced 40%～90% as former at 3～64 months after UAE. Conclusions UAE can treat hysteromyoma effectively in the early stage, and CDFI provides a important method for evaluating the effect of UAE.
