Abstract

The clinical and radiologic findings of 255 patients with AcomA aneurysms treated with coil embolization between January 2005 and March 2014 were retrospectively reviewed We performed univariate and multivariate analyses to evaluate the associations between morphological variables and rupture statusThe number of patients with AcomA fenestration was 17 out of 255 66  There were no statistically significant differences between the fenestration group and nonfenestration group in clinical and morphological characteristics Multivariate logistic regression tests showed that superior direction of aneurysm dome OR 2802 p = 0023 presence of a bleb OR 5998 p  0001 high aspect ratio OR 3138 p = 0009 size greater than 7 mm OR 3356 p = 0013 and AcomA fenestration OR 4135 p = 0026 were significantly associated with AcomA aneurysm ruptureThe results of this study demonstrated that a fenestrated AcomA is associated with risk of aneurysm rupture Therefore AcomA fenestration can be considered as an important morphological risk factor for rupture along with other known risk factors such as the direction of aneurysm dome a bleb high aspect ratio and size
