1、颅内交通动脉瘤的发生与Willis环变异的关系范晓1，吕发金1，罗天友1，彭娟1，方维东1，孙晓川2（重庆医科大学附属第一医院：1放射科，2神经外科，重庆400016）摘要：目的根据64层螺旋CT数字减影血管成像（volumecomputedtomographydigitalsubtractionangiography,VCTDSA）的表现探讨前交通动脉瘤（ACoAA）和后交通动脉瘤（PCoAA）的发生与Willis环变异的关系。方法分析204例脑血管VCTDSA资料，比较ACoAA、PCoAA患者的性别、年龄及动脉瘤瘤体长径与载瘤动脉的成角情况；探讨ACoAA、PCo
2、AA与Willis环分型的关系。结果结果部分应写明统计值。本组24例ACoAA、63例PCoAA患者无明显年龄差异；ACoAA以男性居多，PCoAA以女性居多；ACoAA、PCoAA瘤体长径与载瘤动脉的成角存在差异；ACoAA组存在Willis环变异的差异，而PCoAA组无明显Willis环变异的差异。结论ACoAA的形成与Willis环血流动力学相关，PCoAA的形成与Willis环血流动力学未见明显相关，ACoAA与PCoAA存在性别差异。关键词：动脉瘤；数字减影；体层摄影术，X线计算机；Willis环中图法分类号：R743.35;R814.43文献标识码：ARel
