子宫肌瘤栓塞术:子宫动脉卵巢支分析

目的：研究子宫肌瘤的供血特点和子宫动脉卵巢支造影表现。方法：164例子宫肌瘤，行选择性双侧子宫动脉插管造影,分析子宫肌瘤的供血特点和子宫动脉卵巢支的发现率以及血管造影表现。结果：所有病例的双侧子宫动脉均参与子宫肌瘤供血，79．9％的病例子宫动脉发出卵巢支，其中80．9％有双侧子宫动脉卵巢支。子宫动脉卵巢支与子宫肌瘤 血管共同起源于迂曲的子宫动脉子宫段，向外、上行供应卵巢。结论：子宫肌瘤由双侧子宫动脉供血，大多数子宫动脉发出卵巢支，子宫肌瘤栓塞术不能避免栓塞卵巢支。

Uterine fibroid embolization:uterine-ovarian anastomotic vessels

Objective:To investigate the angiographic features of the uterine arteries and uterine-ovarian anastomoses in uterine fibroids. Methods:Bilateral catheterization of the uterine arteries was carried out in 164 cases of symptomatic uterine fibroid. Uterine artery angiography was performed to demonstrate the vascular features of uterine fibroid and uterine-ovarian anastomoses. Results: All uterine fibroids were supplied by bilateral uterine arteries. Uterine-ovarian anastomoses were demonstrated in 79. 9% cases,and bilaterally in 80. 9% of them. Uterine-ovarian anastomoses originated with fibroid artery plexus from distal portion of the uterine artery,ascending to the ovary of the same side. Conclusion:The blood supply of the uterine fibroid is from bilateral uterine artery,most of which has uterine-ovarian anastomoses. The embolization of the anastomoses to some extent can not be avoided during uterine fibroid embolization.
