In this study, the purpose was to investigate the relationship between morphology and hemodynamics of IA. Flow_avg-APA and Flow_max-IA was positive correlated with IA size and was negatively correlated with mWT. Flow_avg-APA was positive correlated with IA size when excluding mWT dependence. And no indices were correlated with mWT when excluding IA size dependence. As blood flows into IA, the volume of aneurysm is enlarged, resulting in the reduction of WT. IA size correlated stronger with blood flow than mWT. This study suggests that mWT and hemodynamics may provide additional information other than size, thus improve current IA risk standard.
