子宫肌瘤介入治疗前后CT动态扫描血供变化的研究

目的 研究子宫肌瘤介入治疗前后子宫与肌瘤血供变化。方法 16例单发症状性子宫肌瘤患者接受子宫动脉栓塞治疗,术前、术后7d及术后3个月选择同层面进行CT动态增强扫描,测量正常子宫及肌瘤的CT值,进行栓塞前后对比分析。结果 16例患者每次均顺利完成CT动态增强扫描,术前、术后7d及术后3个月正常子宫组织动态增强曲线及CT值无明显改变,而肌瘤动态增强曲线及CT值有明显改变,肌瘤栓塞后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,有效的新疗法,子宫动脉栓塞后非肌瘤子宫组织血供不受影响。

Evaluation of uterine and fibroid blood supplies before and after uterine artery embolization with dynamic enhanced CT scan

Objective To research the blood supply changes of uterine and fibroid before and after UAE for uterine fibroids.Methods Sixteen patients with symptomatic uterine myoma were treated by Seldinger's bilateral uterine arteries embolization.The same level dynamic enhanced CT scans were undertaken 7 days before and after the procedure with another one 3 months later.The CT values of uterine and fibroid were measured and analyzed. Results 16 cases finished the same level dynamic CT enhancement scans successfully. The dynamic enhanced curves and the CT values showed no significant difference in uterine but had significant difference in fibroids. The fibroids were in a state of ischemia after the procedure.Conclusions Selective uterine arterial embolization is a new safety and effective method for treatment of uterine myoma.
