背景与目的：血流分流支架治疗颅内分叉动脉瘤可导致远端血管在亚急性期的口径改变。本研究旨在评估分流支架引起的局部解剖和血流中断是否与颅内分叉血管口径改变有关。材料和方法：对25例接受分流支架治疗的分叉动脉瘤患者进行影像学和人口统计学分析。采用须状图和Mann-Whitney秩和检验来评估解剖数据和口径变化是否可以联系起来。对称/不对称定义为直径比1 =对称与直径比
BACKGROUND AND PURPOSE: Treatment of intracranial bifurcation aneurysms with flow-diverter stents can lead to caliber changes of the distal vessels in a subacute phase. This study aims to evaluate whether local anatomy and flow disruption induced by flow-diverter stents are associated with vessel caliber changes in intracranial bifurcations.MATERIALS AND METHODS: Radiologic images and demographic data were acquired for 25 patients with bifurcation aneurysms treated with flow-diverter stents. Whisker plots and Mann-Whitney rank sum tests were used to evaluate if anatomic data and caliber changes could be linked. Symmetry/asymmetry were defined as diameter ratio 1 = symmetric and diameter ratio
