CT血管成像对子宫动脉开口变异显示的临床价值

Value of the CT Angiography in Displaying the Anatomical Variations of the Origin of Uterus Artery

目的通过CT血管成像(CTA)研究子宫动脉开口位置的解剖学变异,为妇科手术或者介入治疗提供术前评估参考。方法回顾性收集112例曾接受过腹盆CTA检查患者的扫描图像,对其进行子宫动脉的三维重建,从而了解子宫动脉的开口变异情况。结果112例患者(224侧),平均年龄为(31.4±6.6)岁,平均子宫体积为(95.6±26.8)cm^3,其中144侧子宫动脉起自臀下动脉,占64.3%,51侧起自髂内动脉,占22.8%,29侧子宫动脉与臀上动脉、臀下动脉同时直接由髂内动脉发出,占12.9%。其中同一患者左右侧子宫动脉开口位置一致者有68例,占60.7%,不一致者有44例,占39.3%。结论CTA作为一种快捷、无创、经济的新检查方法,能较好地显示子宫动脉开口位置的变异情况,对介入治疗及盆腔手术有重要的指导意义。

Objective To study the anatomical variations of the origin of uterine artery(UA)by three-dimensional (3D)reconstructed computed tomography angiography(CTA)and facilitate the preoperative evaluation for gynecological surgeries or interventional therapies. Method The CTA findings of 112 patients with an average age of(31.4±6.6)years old who had received a pelvic CTA and undergone 3D reconstruction of the uterine artery were retrospectively analyzed. Results The average uterine volume was(95.6±26.8)cm 3 .Of the UA 224 sides,144 sides(64.3%)arose from the interior gluteal artery and 51(22.8%)from internal iliac artery;in 29 sides(12.9%),the uterine artery,the inferior gluteal and the superior gluteal arteries arising as a trifurcation.The origin of UA was consistent between left and right sides in 68 patients(60.7%)and not in 44 patients(39.3%). Conclusion As a rapid,noninvasive,and economic technique,CTA can effectively display the anatomical variations of the origin of UA and thus can be used to guide interventional therapies and gynaecological surgeries.
