Morphometric predictors of posterior circulation aneurysms risk rupture.
Intracranial aneurysms (IAs) of the posterior circulation (PC) rupture more frequently and their morbidity and mortality rates are higher compared to anterior circulation. Morphological parameters such as size ratio (SR), inflow angle and parent artery geometry are believed to contribute significantly in determining IA risk rupture. The aim of this study is to establish angiography-based morphometric predictors of PC IA risk rupture. ⋯ The SR and inflow angle proved to be relevant predictors in estimating the aneurysm risk rupture of the posterior cerebral circulation.
