Clinical study on hysteromyoma treated with uterine artery embolization / 介入放射学杂志

ABSTRACT

Objective To study the therapeutic effect, side-effect and safety of uterine artery embolization of hysteromyoma with pinyangmycin and lipiodol emulsion. Methods Embolization carried out selectively through uterine artery with pinyangmycin and lipiodol emulsion of 158 hysteromyoma was followed up for 3-18 months with observation of the size of hysteromyoma, the change of corpus uteri and the degree of reactions. Results All cases were embolized successfully including 150 cases of bilateral and 8 cases of unilateral uterine arterial embolization. The appearance of uterine arteries showed obvious arterial enlargement with spiral hypervasculature, tumor staining and prolonged opacification. Six patients underwent hysteroectomy 1 week after the embolization. The specimens demonstrated flaky necrosis with small bloody specks under pathologic examination. The alleviation rate of symptoms were 90.5% with recovery of normal menstrual cycle as 89.4%. The compressive symptoms of hypogastric pain and abdominal distention disasppeared in 91.3%. The reduction in size of hysteromyoma and corpus utei were 80% and 48% on average respectively. Conclusion The primary results demonstrates that uterine artery embolization of hysteromyoma is safe and effective, with low complication rate and more advantage over surgical approach.
