Abstract:
In recent years, through the measurement and analysis of size ratio(SR), inflow angle (IFA), volume-to-ostium ratio(VOR), flow angle(FA), parent-daughter angle(PDA), A1- A2 diameter ratio(A1/A2), a ratio of aneurysm volume to bounding sphere volume(AVSV), a ratio of aneurysm surface to bounding sphere surface (AASA), some international scholars assessed aneurysm rupture risk, and had made some preliminary progress. Research showed that the geometry parameters had the objective significance for the evaluation of the risk of aneurysm rupture, and the bigger the SR, IFA, VOR, FA, A1/A2, AVSV, AASA, the easier the rupture of aneurysms. The smaller the PDA, the easier the rupture of the aneurysms.
