分析子宫动脉起源及开口情况对栓塞治疗子宫肌瘤的意义

目的对子宫动脉起源及开口情况进行分析,提高栓塞治疗子宫肌瘤的成功率。资料与方法71例子宫肌瘤患者进行双侧髂内及子宫动脉造影,观察子宫动脉起源及开口情况,并比较用不同投照角度造影对子宫动脉的显示情况。结果40.8%子宫动脉起源于臀下阴部干;29.6%源于臀下动脉;18.3%源于阴部内动脉,8.5%源于脐动脉,2.8%髂内动脉主干。47.3%子宫动脉在正位造影显示较好,86.2%子宫动脉在10°~30°右斜位造影或10°~30°左斜位造影显示较好。结论多数患者子宫动脉发自髂内动脉分支;斜位造影显示子宫动脉优于正位造影。

The Role of Origin and Opening of Uterine Artery in the Embolization of Leiomyomas in the Uterine

Objective To analyze the origin and opening of the uterine artery in order to improve the success rate in the embolization of uterine leiomyomas. Materials and Methods Angiography of bilateral internal iliac arteries and the uterine artery was performed in 71 patients with uterine leiomyomas and the origin and opening of uterine artery were observed in different views. Results The uterine artery originated from the pudendal branch of inferior gluteal artery in 40.8% of 71 cases, from the inferior gluteal artery in 29.6%, from the internal pudendal artery in 18.3%, from the umbilical artery in 8.5%, and from internal iliac artery in 2.8%. Posterior-Anterior projection of the angiography showed the uterine artery well in 47.3% of all cases, whereas oblique projection identified the uterine artery well in 86.2%. Conclusion The majority of the uterine artery originated from the branches of the internal iliac artery. The oblique projection of the angiography displayed the origin and opening of uterine artery better than the front projection of the angiography.
