      【摘要】 目的 探讨X线电子计算机断层扫描血管成像(CTA)检查对研究女性髂内动脉分型和子宫动脉起
源及角度的意义。方法 选取 2011年 7月至 2012年 12月因各种盆腔病变在我院行盆腔CTA检查的 108例患
者，通过StartVitrea2工作站对图像进行后处理，参照Adachi等的分型标准对髂内动脉进行分型及对比分析，并对
子宫动脉的起源及角度进行研究。结果 髂内动脉分型情况：Ⅰ型占61.2% (132/216)、Ⅱ型占9.7% (21/216)、Ⅲ
型24.1% (52/216)、Ⅳ型4.7% (10/216)、V型占0.5% (1/216)。此外，子宫动脉起源以臀下阴部干最常见(40.1%)，其
次是髂内动脉主干和阴部内动脉，所占比例分别为19.3%和18.4%；子宫动脉的夹角小于30°约占62.3%，其开口
显像的最佳角度多常见于15°~30°。结论 术前行CTA检查可以清楚地了解髂内动脉分型和子宫动脉起源及角
度，对介入治疗及盆腔手术有重要的指导意义。

【Abstract】 Objective To explore the significance of computed tomography angiography (CTA) examina-
tion in studying classification of the internal iliac artery as well as the uterine artery origin and angle of females.
Methods The original CTA datasets of 108 patients with all sorts of pelvic lesions were collected in the Panyu Cen-
tral Hospital from July 2011 to December 2012. The datasets were input into StartVitrea2 workstation for reconstruct-
ing. The internal iliac arteries were classified according to Adachi et al and analyzed comparatively. The origin and an-
gle of the uterine artery were studied. Results All of the internal iliac arteries (n=216) were classificated. TypeⅠ ac-
counted for 61.1% (132/216), typeⅡ accounted for 9.7% (21/216), with typeⅢ for 24.1% (52/216), typeⅣ for 4.6%
(10/216), type V for 0.5% (1/216). In addition, most of the uterine arteries were originated from the trunk of inferior
gluteal and main pudenda artery (40.1%), and less from the internal iliac artery (19.3%) and internal pudendal artery
(18.4%). The angle of uterine artery less than 30° accounted for 62.2%, and the opening angle of best display more
common was 15°~30°. Conclusion Preoperative CTA examination can clearly display the classification of the inter-
nal iliac artery and origin and angle of the uterine artery, which has important guiding significance to interventional
therapy and pelvic surgery.
