PVA微粒子宫动脉栓塞治疗子宫肌瘤(附16例分析)

目的 探讨子宫动脉栓塞术（UAE）治疗子宫肌瘤的技术方法并评价临床疗效。方法 用直径为350－500μm的PVA微粒及自制大小1mm左右的明胶海绵颗粒对16例诊断明确的子宫肌瘤患者进行双侧子宫动脉栓塞，术后随访至少6个月，观察其临床症状及肌瘤大小变化。结果 所有以月经量增多为主要症状的患者术后月经量基本恢复正常；术后子宫体积平均缩小48.9%，肌瘤体积平均缩小49.2%，无严重并发症发生。结论 UAE能有效地消除临床症状，缩小肿瘤体积，是一种较好的治疗手段，易被患者所接受。

Uterine arterial embolizaton with PVA particles as a the treatment of uterine leiomyomas (with the analysis of 16 cases)

Objective To investigate the technic and the clinical effect of uterine arterial embolization as the treatment of uterine leiomyoma. Methods Bilateral uterine arterial embolization was performed in 16 patients with uterine leiomyoms. The embolic agents were polyinyl alcohol (PVA) particles sized 350um - 500 um in diameter and gelfoam. The clinical manifestations and the size of tumors were investigated in a 6 - month post - procedure follow -up. Results In all patients with hypermenorrhea was relieved, in average the uterine size was reduced by 48. 9% and the size of tumor was reduced by 49. 2% after the intervention. No serious complication occurred. Conclusion Uterine arterial embolizaton is effective in relieving the clinical symptoms and debulking the leiomyoma. It is a valuable technique, and easily accepted by patients.
