【摘要】 目的 探讨大脑前动脉(ACA)分叉形态学与前交通动脉瘤朝向的关系,分析血管内支架改变外侧角角度在临床防治动脉瘤中的作用。方法 对698例患者作DSA造影,其中171例前交通动脉瘤患者和527例无瘤患者。测量ACA分叉角度、动脉瘤朝向,通过动脉分叉顶端纵线和横线采线方法定量分析血流动力学应力(动态压力、总压力、剪切力、涡流强度和应变率)。结果 前交通动脉瘤多偏向小角度外侧角(P<0.001)。计算流体力学(CFD)分析40例ACA分叉顶端结果显示,与ACA- A1段形成小角度的分支血管管壁Peak位点血流动力学应力显著大于对侧分支血管(P<0.001)。结论 与主干血管形成小外侧角的分支血管管壁异常增大的血流动力学应力,可能促进动脉瘤形成。临床上采用弹簧圈结合支架治疗动脉瘤时选择将一字形支架植于小外侧角处,利用支架自身弹性回复扩大外侧角,可能是防治动脉瘤的有效方法。
