Abstract：Objective To identify morphological parameters associated with intracranial aneurysms (IAs) rupture.Methods Seven morphological parameters were evaluated in 114 patients with saccular IAs (61 unruptured,53 ruptured),including the ratio of aneurysmal diameter to parent artery diameter (size ratio,SR),ratio of aneurysmal height to parent artery height,ratio of aneurysmal height to aneurysmal neck width,ratio of aneurysmal height to width,angle between the parent artery longitudinal axis and aneurysmal diameter (incidence angle of blood flow) and angle between the plane where the aneurysmal neck was and the parent artery (aneurysmal inclination angle) and angle between the directions in which blood flew into and from the aneurysm (parent artery angle).The relationship of these factors with the aneurysm rupture was statistically analyzed.Results The multivariate Logistic regression analysis showed that small length of aneurysm (OR=0.470,95％ CI 0.286～0.771,P=0.003),high SR (OR=18.998,95％ CI 2.851～126.607,P=0.002) and big aneurysm inclination angle (OR=1.073,95％ CI 1.023～1.125,P=0.004) were independent risk factors related to the rupture of intracranial aneurysms.Conclusions It is suggested that the SR,aneurysmal inclination angle and length of aneurysms may be important factors related to the rupture of the intracranial aneurysms.
