An analysis of the related problems in uterine artery embolization for uterine fibroids and adenomyosis

Objective:To analyze the related problems in uterine artery embolization(UAE) for uterine fibroids and adenomyosis.Methods:The normal uterine artery of 28 females undergoing pelvic angiography and 14 patients with uterine fibroids (n=11) and adenomyosis (n=3) undergoing UAE were prospectively analyzed.Biopsy was performed in all cases by ultrasound guiding before operation.Results:The source of uterine artery was demonstrated in only 9.4% on the front projection, 86.21% of which was covered mostly by superior gluteal artery.The ideal demonstration of the uterine artery was on the projection of 25～30 degree toward left or right anterior obliquity with 15 degree at which the tube tilts the head.The rate of ultrasound diagnosis consistent with the result of pathology was 91%(10/11)in uterine fibroids and 100%(3/3)in adenomyosis,respectively.Following the unilateral ovarian branch embolization,the sexual hormone level, menstruation and the function of the overy was normal.Conclusion:Pathological biopsy is in favor of objective and scientific evaluation for interventional treatment for both the diseases.The best angle to reveal the opening of the uterine artery is 25～30 degree of left or right anterior obliquity with 15 degree at which the tube tilts the head.Moreover,a unilateral ovarian branch embolization of uterine artery doesn't affect the ovary function.
