子宫肌瘤栓塞治疗前后CT动态扫描研究

Research Blood Supply Changes of Uterine and Fibroid with Dynamic Enhance CT Scan before and after Uterine Artery Embolization

目的 探讨子宫肌瘤 CT动态扫描方法 ,观察子宫肌瘤介入治疗前后子宫肌瘤血供状态及其大小的变化。 方法 2 6例单发症状性子宫肌瘤患者接受 U AE治疗 ,术前 ,术后 5～ 7d及术后 3～ 5月选择肌瘤最大层面进行 CT增强扫描 ,测量子宫肌瘤的 CT值及其大小 ,进行栓塞前后对比分析。 结果 2 6例患者每次均顺利完成动态增强 CT扫描 ,术前 ,术后 5～ 7d及术后 3～ 5月子宫组织动态增强曲线及 CT值无明显改变 ,而肌瘤则有明显变化 ,处于持续性缺血状态。 结论 子宫动脉栓塞术治疗子宫肌瘤是一种安全。

Objective To research the blood supply changes of uterine and fibroid before and after UAE for uterine fibroibs. Methods 16 cases with symptomatic uterine myoma were treated by Seldinger's bilateral uterine arteries embolization. The same level dynamic enhance CT scans underwent preoperation, 7 days and 3 months of postoperation. The CT values of uterine and fibroid were measured and analyzed. Result 16 cases finished the same level dynamic CT enhance scan successfully. The dynamic enhance curves and the CT values had no significant difference in uterine and had significant difference in fibroids. The fibroids were in a state of ischemic after postoperation. Conclusion Selective uterine artery embolization is a new safety and effective method for treatment of uterine myoma.
